Abstract :

The present study sought to investigate the effects of face-to-face and web-based group dynamic assessment (GDA) on the speaking skills of Iranian intermediate EFL learners. A total of 100 participants from Ariana Institute in Rasht were involved in the study, with 36 introverted and 36 extroverted learners selected based on their scores on the Oxford Placement Test (OPT) and Eysenck’s Personality test. These participants were then divided into experimental and control groups. Each experimental group, comprising 12 participants, underwent either face-to-face or web-based GDA sessions, while the control groups received traditional instruction. The research design included a pretest, 15 treatment sessions, and a posttest to assess the progress of speaking abilities among the learners. The statistical analysis, which included paired samples t-test and one-way ANOVA, indicated significant enhancements in speaking skills among the learners who participated in the experimental GDA sessions compared to those in the control groups. Notably, introverted learners in the web-based GDA group exhibited superior speaking abilities, whereas extroverted learners showed more improvement in face-to-face GDA sessions. These results have important implications for English language educators and researchers in Iran, highlighting the significant influence of GDA delivery mode on the speaking proficiency of EFL learners, particularly in relation to their introverted or extroverted traits. Such findings can offer valuable insights for pedagogical approaches and theoretical frameworks in English language teaching in Iran.

Introduction

The aspiration to achieve fluency in spoken English is a common objective among the majority of EFL learners, as highlighted by Kazemi and Tavassoli (2020) and Teferi (2023). This goal has consistently been a primary focus for language learners, given that speaking is considered a productive skill that educators strive to enhance. By empowering EFL learners to produce meaningful statements during interactions, speaking encourages the active use of language (Azizi et al., 2020). Furthermore, speaking is acknowledged as an interactive, social, and contextualized form of communication. It plays a crucial role in establishing and nurturing social connections, expressing emotions, and conveying personal identities (Tridinanti, 2018). As noted by Mardiah (2022), achieving proficiency in speaking is often deemed the most critical aspect of learning a second or foreign language, with proficiency assessed by the ability to engage in discussions in the target language. However, speaking presents challenges for students as it requires proficiency in various aspects, such as pronunciation, grammar, vocabulary, fluency, and comprehension (Ghafar & Raheem, 2023).

Additionally, to evaluate students' speaking skills in a specific instructional program, teachers can employ various methods. These methods include formative assessment, dynamic assessment, diagnostic assessment, performance assessment, and so on (Kazemi & Tavassoli, 2020). In this study, the preferred method was dynamic assessment (DA) involved a blend of instruction and assessment of the learners' speaking skills. Through the implementation of this educational system, teachers can accurately assess the overall abilities of the learners, thus obtaining a comprehensive understanding of their capabilities.

According to Özturan and Gürdal (2023), DA is a method that combines intervention with psychological or psychoeducational assessments to create an interactive assessment process. Its main objective is to evaluate a student's current performance level, known as the Zone of Actual Development, as well as their potential for learning with support, referred to as the Zone of Proximal Development (ZPD). As highlighted by Infante and Poehner (2019), by incorporating intervention during the assessment, DA aims to provide a comprehensive understanding of a student's abilities and their capacity to progress with assistance.

In the present study two types of DA has been utilized, face-to-face and web-based GDA. Ahmadi̇ and Besharati̇ (2017) defines face-to face GDA as an interactive and scaffolded evaluation process that surpasses the mere measurement of a student's individual performance. This methodology encompasses a pretest, instructional or intervention phase, and a posttest, which allows the evaluator to observe the student's reaction to the intervention (Şükür et al., 2023). As highlighted by Annandale et al. (2021), by classifying students into those who can independently solve a problem, those who can solve it with assistance, and those who are unable to solve it at all, face-to-face DA provides a more comprehensive understanding of the student's progress compared to solely assessing their independent performance. Similarly, Sarabi Asl et al. (2024) state that this assessment method proves particularly advantageous for students facing learning difficulties, cultural or linguistic diversity, or exhibiting poor performance on conventional tests. It empowers evaluators to identify specific cognitive or non-intellectual factors that may impede the student's performance and evaluate their responsiveness to targeted instruction (Annandale et al., 2021).

The notion of web-based GDA involves the amalgamation of DA principles with online group instruction and assessment to enhance language learners' language proficiency by providing interactive feedback within their ZPD in a digital setting (Fathi et al., 2023). Web-based GDA fosters collaborative and interactive feedback opportunities for learners to collaboratively construct new knowledge within their ZPD, diverging from the more direct corrective feedback commonly associated with non-GDA approaches (Alemi et al. 2019). The incorporation of web-based GDA into language instruction provides practical advantages for educators aiming to enhance their online teaching methodologies with interactive and scaffolded assessment strategies. The automated features of online systems enable efficient and personalized delivery of feedback to learners (Ahmadi̇ & Besharati̇, 2017).

Moreover, the integration of DA methods encompasses a combination of instructional and evaluative elements. Employing this pedagogical strategy can support educators in acquiring a thorough comprehension of students' capacities (Davin, 2013). In particular, administering assessments within ZPD allows teachers to understand learners' skills and facilitate their advancement through suitable guidance (Alsaadi, 2021).

Despite the existing body of research on dynamic assessment in various areas such as reading (Kushki & Nassaji, 2024; Kao & Wu, 2022; Mustiah et al., 2024) writing (Rezai et al., 2024; Shrestha & Shrestha, 2020), and listening skills (Zarei & Shishegarha, 2024; Zhang, 2023) there seems to be a limited focus on utilizing DA to enhance students' speaking proficiency (Ebadi & Asakereh, 2017; Son & Kim, 2017; Şükür et al., 2023). Furthermore, according to Shafipoor and Latif (2020), the effect of learners' personality traits on DA remains unexplored, despite its potential importance in both educational instruction and assessment. Estaji and Farahanynia (2019) stated that processes of teaching and assessment among these differences, the introversion-extroversion spectrum emerges as a significant characteristic that may necessitate further exploration within the realm of DA. Given that learners demonstrate diverse learning styles and preferences, recognizing these diversities within the context of DA could enhance evaluators' capacity to address DA in a more comprehensive manner (Radić-Bojanić, 2020; Shafipoor & Latif, 2020).

Consequently, this research gap has motivated the current study to explore this aspect further considering face-to-face and web-based GDA focusing on introversion and extroversion factors which has been rarely studied in the domain of speaking and DA.

Literature Review

Initially introduced to Western educators and researchers by Lurii︠A (1966) who was influenced by Vygotsky's ZPD (Sharafi & Sardareh, 2016), DA has its roots in the concept of ZPD, which represents the gap between a learner's independent abilities and what they can achieve with assistance, in both assessment and educational contexts (kurt, 2022). Originally utilized in studies involving children experiencing learning challenges, DA has evolved over time to encompass broader educational settings, including general education and adult learners. It has been integrated into a comprehensive framework for second language pedagogy, suggesting that the principles of DA offer a systematic approach to engaging with second language learners, providing valuable insights into their language skills, and supporting their ongoing development (Le et al., 2023; Poehner et al., 2019).

Vygotsky (1978) posited that in DA research, teaching and assessment should be integrated rather than separated. The primary focus should be on facilitating the learning of students, which can be enhanced through student engagement in activities, peer interactions, and teacher guidance. By utilizing mediators, learners can attain greater independence in completing tasks (Abassy & Mashhadi Heidar, 2020). Meanwhile, Özturan and Gürdal (2023) state that dynamic testing is a method that considers individual characteristics and their impact on education, emphasizing the role of mediation in the assessment process. These approaches prioritize the learning process over the final learning outcomes.

Despite the limited number of studies focusing on the comparison between face-to-face and web-based GDA in EFL speaking classes concerning introversion/extroversion, there has been a significant increase in research dedicated to investigating the implementation and benefits of DA in educational settings. The impact of DA on diverse student groups has been found to differ across various research studies. For example, Son and Kim (2017) explore the potential of DA in EFL speaking classes inspired by Vygotsky’s (1978) theory. The results suggest that the feedback provided by the mediator and the learner's reactions progressed in harmony, leading to a decrease in direct guidance from the mediator and an increase in self-initiated actions by the learner. Furthermore, a detailed examination reveals a significant relationship between the learner's advancing language skills, the dynamic interactions, and the cognitive and collaborative strategies used in sense-making.

Similarly, Ahmadi Safa et al. (2016) conducted a study to examine the impact of different models of DA on the speaking abilities of Iranian EFL learners. The researchers recruited three groups of advanced English language learners who were exposed to interventionist DA, interactionist DA, and non-DA approaches. The results revealed that participants who received interactionist DA exhibited superior performance compared to those in the other groups. However, the study's reliance on purely quantitative data limited the depth of understanding regarding the cognitive processes of the participants. DA aims to capture the cognitive development of learners, necessitating a qualitative approach for a more comprehensive interpretation of the results.

Using a mixed-method design, Estaji and Farahanynia (2019) studied on the impact of two main methods of DA, namely the interventionist and interactionist, on learners' oral narrative performance and anxiety levels. The results, derived from analyzing the collected data after administering a posttest, indicated a significant improvement in the oral performance of both groups, along with a reduction in their anxiety levels. Additionally, a semi-structured interview was carried out, revealing that the Interactionist Group experienced increased anxiety levels, mainly attributed to feelings of disruption and loss of face.

Shafipoor and Latif (2020) carried out a research study focusing on investigating the impact of interventionist DA on the academic essay writing of introverted and extroverted English language translation students. Although the study's findings revealed a significant statistical influence of DA on the academic writing performance of both introverted and extroverted learners, extroverted learners showed higher scores in their posttests compared to their introverted peers, indicating a distinct response to the intervention. Furthermore, the results from the attitude questionnaire revealed that extroverted students had a more positive attitude towards the use of DA in academic writing tasks compared to introverted students. This difference in attitude towards the application of DA further emphasized the varying perceptions and responses of extroverts and introverts in the context of academic writing interventions.

In an explanatory sequential mixed-methods study, Fathi et al. (2023) investigated if web-based DA had any effect on the grammatical accuracy, autonomy, and attitudes of 60 male EFL learners. The outcomes of the ANCOVA and Mann-Whitney U test demonstrated a notable rise in the average scores for grammar accuracy and autonomy among the learners in the web-based DA group in comparison to those in the control group. Moreover, the outcomes of the interviews with the participants displayed a favorable perception towards the web-based dynamic assessment intervention. The qualitative information gathered from the semi-structured interviews with the experimental group supported the quantitative results, offering a comprehensive insight into the impacts of web-based DA on the language skills and attitudes of the learners.

In their research, Kazemi and Tavassoli (2020) explored how dynamic and diagnostic assessments influenced the development of speaking abilities among Iranian EFL intermediate students. Two assessors evaluated both the speaking pretest and posttest, with the data being analyzed through a two-way ANOVA. The results showed an improvement in performance for all three groups from the initial test to the final one. Interestingly, while both the diagnostic and dynamic assessment groups showed significant progress, the difference in their advancements was not deemed statistically significant. Furthermore, Sarabi Asl et al. (2024) studied four sub-skills related to speaking proficiency in EFL learners: grammatical range and accuracy, vocabulary, fluency, and pronunciation. The results showed that both interactionist and interventionist DA models had a positive effect on speaking proficiency, with varying impacts on different sub-skills. The interactionist DA was more effective in improving grammatical range and accuracy, pronunciation, and vocabulary depth, while the interventionist DA was better at enhancing fluency and vocabulary breadth.

The Problem

In the past, there was a prevailing belief that teaching and assessment were distinct entities, with an emphasis on maintaining their separation to accurately evaluate learners' abilities without any form of support (Quay et al., 2023). However, Vygotsky (1978) challenged this conventional perspective by introducing the novel concept that learning is a collaborative process occurring within a sociocultural framework (Kusmawan, 2023).

Despite participating in various speaking courses, Iranian EFL learners continue to express apprehensions regarding their spoken English proficiency, particularly in authentic language settings. English instructors have been urged to explore alternative pedagogical approaches to enhance students' speaking abilities in the classroom; however, these endeavors have often yielded unsatisfactory results (Bavandi-Savadkouhi & Mostafaei-Alaei, 2023; Kardoust & Saeedian, 2021, Salimi & Khazaee Kouhpar, 2024). The amalgamation of institutional, teacher-related, and learner-related factors such as their personalities, taking into account their individual characteristics, poses significant obstacles to the development of robust speaking skills among Iranian EFL students within the existing educational framework. Addressing these multifaceted challenges is imperative for enhancing speaking instruction and outcomes (Laila et al., 2023; Nasri et al., 2021; Omar, 2023).

Purpose of the Study

The purpose of this study was to investigate how face-to-face and web-based GDA impact the speaking proficiency of Iranian intermediate EFL learners, while considering their introverted and extroverted personality characteristics. The researchers were driven by the need to address the existing gap in the literature and offer a viable solution to the challenges associated with teaching and learning speaking skills through the utilization of these underexplored GDA formats within the speaking domain.

Research Questions

RQ1. Can the utilization of face-to-face interactionist GDA significantly affect the speaking abilities of Iranian intermediate EFL learners?

RQ2. Does web-based interactionist GDA impact the speaking ability of Iranian intermediate EFL learners?

RQ3. Are there any variations in the effects of face-to-face GDA compared to web-based GDA based on the introverted/extroverted traits of Iranian intermediate EFL learners?

Method

Design of the Study

The current investigation utilized a pre-test and post-test research design that was quantitative in nature, adhering to the scientific method by employing deductive reasoning to examine hypotheses and derive conclusions from the gathered data. The primary aim was to gather numerical data that could be objectively analyzed to reveal patterns, correlations, and cause-and-effect relationships (Creswell & Creswell, 2018). In this study, the dependent variable (DV) under scrutiny was the speaking proficiency of intermediate EFL learners, with the objective of determining whether it could be influenced by the implementation of the independent variable (IV), which encompassed face-to-face and web-based GDA.

Participants

The participants of the study, 72 out of 100 male and female students were selected from among Iranian intermediate EFL learners with the age range of 16-18 in Ariana institute in Rasht, Gilan, Iran.

Material

The American English File 3rd Edition

The primary resource employed in this investigation was American English File 3. The selection of this educational material was based on its appropriateness for the research being conducted. Published in 2008 by Oxford University Press, the book authored by Christina Latham-Koenig, Clive Oxenden, and Jerry Lambert includes the Student Book, Work Book, Student’s DVD, Mp3 CD, and Multi Rom DVD. Specifically designed for intermediate level learners in accordance with the CEFR international standard, American English File 3 consists of 7 lessons, concluding with a comprehensive review after the seventh lesson.

An Eysenck’s Personality Inventory (EPI)

The Eysenck Personality Inventory (EPI) was created by Hans and Sybil Eysenck as a psychological evaluation tool. It focuses on measuring two fundamental traits outlined in Hans Eysenck's personality theory, namely extraversion and neuroticism. To address potential response biases, a 9-item Lie scale was added to the original 24-item measures. These traits are considered temperamental aspects of personality that are believed to be inherited and present from birth. As per the EPQ scoring guidelines, an E score falling within the range of 13-24 is labeled as extraverted, whereas a score below 12 is categorized as introverted. Those who score 12 are positioned in the intermediary range between extraversion and introversion (Heinemann, Corrigan & Moore, 2004).

Speaking Pretest and Posttest

The speaking skills assessments utilized in this research were sourced from the review sections of American English File 3 consisting of 10 questions. To ensure uniformity, a separate group of participants with a comparable level of English proficiency to the primary participants were enlisted to undertake the tests. The tests' reliability was assessed through the application of the KR-21 formula, yielding coefficients of 0.81 and 0.83, signifying adequate reliability for the study's objectives. Furthermore, the validity of the tests was scrutinized by experts, including two university lecturers. These experts meticulously analyzed various aspects of the tests, such as the test format, scoring system, distribution of choices, and item selection, affirming the content validity of the tests.

Skyroom Software

The platform is equipped with essential features such as live audio and video communication, presentation tools, a digital whiteboard, screen sharing capabilities, file transfer options, advanced chat features, and the ability to record sessions for future reference.

Group Dynamic Assessment (GDA)

Dynamic Assessment is of great importance in Vygotsky's Sociocultural Theory (SCT), as emphasized by Poehner et al. (2024) who stressed the incorporation of testing and instruction rooted in Vygotsky's principles. Poehner (2009) elaborated on this by introducing the notion of GDA, underscoring the significance of incremental feedback from educators at the communal level to enrich learners' ZPD and enhance their proficiency.

Data Collection Procedure

In order to gather data, an OPT was administered to 100 learners. Subsequently, 72 learners who scored one standard deviation below the mean were chosen. Following this, Eysenck’s Personality Inventory Questionnaires were given to the selected 72 learners, who were then divided into two groups: 36 introverted intermediate learners and 36 extroverted intermediate learners. These learners were further categorized into 6 classes, each consisting of 12 learners. Among these classes, four were designated as experimental groups while the remaining two were control groups. Prior to commencing the teaching sessions, a pretest was conducted. One introverted and one extroverted experimental group were taught speaking skills through face-to-face GDA, while another introverted and extroverted experimental group were taught speaking skills through web-based GDA over a span of 15 sessions. The two control groups received conventional teaching methods for speaking skills.

During GDA classes, the learners engaged in the following procedures: Initially, they conducted research on the assigned topic prior to the class session. Subsequently, they were organized into 3 groups and collaborated in groups of 4 for a speaking activity. Following this, all learners in each group took turns discussing the topic while the others listened attentively. In instances where they encountered difficulty with a word, they were permitted to consult a dictionary, seek assistance from other group members, or request help from the teacher. Each group then posed a question related to the topic, to which the other groups provided answers. If there was any confusion regarding the question, the other groups clarified it, after which the teacher provided further explanation for better understanding. The teacher then validated their correct responses. The teacher documented the errors made by each group on a piece of paper to display on the board for further elaboration. Subsequently, the learners' mistakes were highlighted on the board to delve deeper into pronunciation, grammar, or other errors. The learners assisted the teacher in explaining the mistakes or errors, expressing their thoughts without any pressure. Finally, the teacher summarized and presented key information about the topic on the board for the learners.

The intervention consisted of 15 sessions, with each session lasting approximately 90 minutes. Following the 15 sessions, all participants engaged in a speaking posttest, which included 10 speaking questions. The learners' responses were recorded and assessed using IELTS speaking band scores, focusing on pronunciation, grammatical range and accuracy, lexical usage, and fluency and coherence. Subsequently, the study's hypotheses were compared and analyzed based on the results.

Data Analysis Procedure

Given the quantitative nature of the current investigation, it is imperative to adhere to both descriptive and inferential statistical methods in order to address the research inquiries. In order to tackle the first and second research questions, as well as evaluate the speaking abilities of the learners, paired samples t-test was implemented to compare the pretest and posttest of experimental and control groups. Furthermore, to address the third research question, a one-way ANOVA was utilized to examine the mean variances between groups categorized based on two independent variables across all posttests.

Results

To maintain consistency in the proficiency level of the participants included in the research, the researchers conducted the OPT. Subsequently, the results of the test were evaluated based on the standards outlined in the OPT guidelines. The statistical overview of the groups' achievements in the proficiency evaluation is presented in Table 1.

According to the findings reported in Table 12, the analysis of Scheffe multiple comparisons reveals a significant disparity in the average scores between the experimental groups and the control groups (p = .000). The results also indicated extrovert groups displayed a notable enhancement in posttest results in face-to-face GDA classes and the introvert groups outperformed all other groups in web-based GDA classes.

Discussion

The objective of this research was to investigate the impact of face-to-face versus web-based interactionist group dynamic assessment on the speaking proficiency of Iranian EFL learners at an intermediate level, categorized based on their introverted and extroverted personality traits. The results of conducting paired samples t-tests indicated a significant and noteworthy enhancement in speaking abilities from pretest to posttest for participants who underwent face-to-face or web-based GDA, as opposed to those in the control groups. Moreover, the comparison of the impact of independent variables, introversion, and extroversion, was conducted through one-way Anova analysis, revealing that the introverted experimental group outperformed in web-based and the extrovert group outperformed in face-to-face classes in terms of speaking ability improvement.

Consequently, it is evident that the students demonstrated improvements in their speaking abilities as a result of integrating GDA into the research. The results indicate that the use of these techniques was advantageous for both introverted and extroverted individuals, with only a slight variance in favor of extroverted students in terms of surpassing expectations, ultimately enhancing their speaking proficiency.

The results of the investigation align with the conclusions drawn by Harahap et al. (2024), indicating that the implementation of DA can have a significant positive impact on the speaking proficiency of EFL university students in Indonesia. Furthermore, the study conducted by Petersen et al. (2020) on the influence of DA on language accuracy in EFL settings corroborates the findings of the current research, highlighting the effectiveness of DA in evaluating language skills across diverse learner populations. Similarly, the outcomes of this study are consistent with the research conducted by Sohrabi and Safa (2020), illustrating that the integration of group dynamic assessment in EFL classrooms can enhance learners' oral production skills, boost their motivation, and reduce speaking-related anxiety. Additionally, the findings of QU and LIU (2022) support the notion that interactionist DA shows promise in enhancing oral communication abilities among EFL learners with low proficiency levels, when combined with regular EFL instruction. Moreover, the results of the present study are in agreement with the research by Ghahderijani et al. (2021), indicating that both group-based and computerized DA methods can improve the speaking proficiency of Iranian upper-intermediate EFL learners, with computerized dynamic assessment showing superiority in enhancing specific aspects of speaking such as complexity and accuracy. Lastly, the study conducted by Sarabi Asl, et al. (2022) further supports the findings of the current research, suggesting that while both interactionist and interventionist dynamic assessment approaches can enhance Iranian EFL learners' speaking skills, the interactionist model may be more effective in improving fluency and complexity, whereas the interventionist model could lead to greater gains in accuracy. Additionally, learners expressed more positive perceptions towards the interactionist dynamic assessment approach.

The current study's findings align with prior research on the same topic (Ebadi & Bashir, 2021; Fathi et al., 2024; Makhachashvili & Semenist, 2022; Mustiah et al., 2023). However, there are studies that have presented conflicting results regarding specific models of team-teaching. For example, Kazemi and Tavassoli's (2020) investigation revealed that both web-based/mobile-mediated and face-to-face dynamic assessment methods were effective in enhancing the speaking skills of EFL learners compared to a control group. Nonetheless, the study did not find a significant difference in the effectiveness of these two assessment approaches. Furthermore, it was revealed that the use of both web-based and face-to-face interactionist dynamic assessment methods resulted in similar success in enhancing the argumentative essay writing skills of EFL learners. Both approaches showed positive outcomes when compared to a control group. Conversely, mobile-mediated dynamic assessment was determined to be more effective than face-to-face dynamic assessment in improving the writing fluency and strategy awareness of EFL learners (Kaveh & Rassaei, 2022).

Conclusions

The study examined the effectiveness of face-to-face and web-based GDA in improving the speaking skills of introverted and extroverted students. The findings indicated that GDA had a significant impact on the speaking performance of both groups, with introverted students demonstrating better results in web-based while extroverted students performed better in face-to-face GDA classes. Face-to-face assessment provides a more holistic view of student progress compared to evaluating individual performance in isolation. The incorporation of web-based GDA in language teaching offers practical advantages for educators seeking to enhance their online instructional techniques with interactive assessment tools. The automated functions of online platforms enable prompt and personalized feedback delivery to learners.

Moreover, the integration of assessment methods merges instructional and evaluative aspects. Adopting this educational approach can aid educators in gaining a deeper insight into students' capabilities. Additionally, the research underscores the importance of offering tailored support to introverted and extroverted students based on their learning preferences and strengths in speaking abilities. By considering students' personality traits and the characteristics of speaking evaluations, instructors can tailor teaching strategies to effectively boost students' speaking skills in EFL settings.

Implications

The outcomes of the current research can be advantageous for both students and teachers. The utilization of interventionist face-to-face and web-based GDA techniques can effectively cater to the diverse learning styles and preferences of introverted and extroverted EFL learners. Educators must recognize the significance of employing a variety of assessment methods to address the individual needs of each student (Rashidi & Bahadori Nejad, 2018). Additionally, online GDA tools can be particularly helpful for introverted learners, as they may feel more comfortable expressing themselves through written or digital mediums (Fathi, et al., 2023). By integrating these tools, teachers can assist introverted students in boosting their confidence in speaking and promoting active participation in classroom activities. Conversely, extroverted learners typically thrive in social and collaborative environments. GDA approaches can play a crucial role in leveraging the strengths of these students by encouraging them to assume leadership roles during group assessments (Shafipoor & Latif, 2020). This method can enhance their speaking abilities and instill a sense of empowerment (Poehner & Leontjev, 2023). Offering personalized feedback and assistance to both introverted and extroverted learners is vital throughout the assessment process (Abdulaal, 2022). Educators should aim to establish a supportive and inclusive learning atmosphere that inspires students to step out of their comfort zones and enhance their speaking skills. By combining face-to-face interventionist techniques with web-based group dynamic assessment, teachers can create a more engaging and interactive learning setting for all EFL learners. This holistic approach can effectively foster the development of speaking skills in students with diverse personality traits and learning preferences (Ahmadi̇ & Besharati̇, 2017; Şükür et al., 2023).

Suggestions for Further Research

The research findings suggest that web-based and face-to-face GDA can have a positive impact on language skills like writing and grammar, but there is a lack of direct evidence comparing their effects on speaking abilities (Kuhi et al., 2023). Further investigation is necessary to determine which GDA type is more effective in enhancing the speaking abilities of EFL learners. Future studies can explore various forms of GDA to evaluate the speaking skills of introverted and extroverted EFL learners, including a comparison of collaborative and competitive assessment strategies and their influence on oral proficiency. The current research adopted a quantitative methodology, while upcoming researches can utilize qualitative or mixed-method approaches to analyze how individual learner characteristics such as attitudes, motivation, anxiety, and learning style affect the efficacy of interventionist GDA in improving speaking abilities among EFL learners.

While the present study concentrated on one semester of teaching speaking skills, future investigations can investigate the lasting impacts of interventionist GDA on speaking proficiency and overall language skills, considering learners' personalities to determine the enduring implications of face-to-face and web-based assessment methods. Moreover, forthcoming research can identify any barriers or facilitators to the implementation of these methods. The current study contrasted face-to-face and web-based GDA, but future investigations can explore the advantages of integrating interventionist face-to-face and web-based GDA with other instructional methods to improve speaking skills among Iranian EFL learners with diverse personality traits. Furthermore, subsequent studies can concentrate on the potential synergies between these assessment methods and other pedagogical approaches like task-based learning and content-based instruction to enhance language skills effectively.
