  Decimal numbers are one of the basic issue in school mathematics. After introducing Decimal numbers to students in elementary course, they are usually used as one of the important concept as generalizable tool in upper grades and they play important role in mathematics. In this research, inferential (contingency table) and descriptive statistics are used for analyzing data.The aim of this research is to study, categorization and comparing the students’ misconceptions in comparing decimal numbers. The sample in this research consists of 103 students in 6th, 7th and 8th grade, chosen from the available statistical population. The data were collected by using “Decimal comparison tests” and answers were analyzed in accordance with the assigned criteria. According to the achieved results relating to the misconceptions of Decimal numbers comparison, the 8th grade students had the most amount of misconception in comparison with the 6th and 7th grade students and statistically there was a meaningful deference between the results. Showed that most discovered misconceptions in other research works, also showed themselves in this research. Meanwhile, misconception expands as the student’s progression the course. In addition, a pattern is introduced for discovering misconceptions of Decimal numbers comparison by the help of previous research conducted by others mentioned in the literature. Manuscript profile

    Abstract: The purpose of this study was validating the Mathematics Teaching Efficacy Beliefs Instrument (MTEBI) in pre-service teachers in primary schools. The population of this research included all college students in the field of primary education in South Khorasan province (N=186). To study reliability and validity of the questionnaire, 140 pre-service teachers were chosen by cluster sampling method from Teaching Training Center of Birjand. Then, Mathematics Teaching Efficacy Beliefs Instrument (MTEBI) was administered. The instrument validity was measured using factor analysis methods and Cronbach's alpha was used to evaluate the reliability. The results of factor analysis showed that this questionnaire include two fundamental underlying factors  since all the items were loaded under two factors which are self-efficacy and expected results of teaching. The results also showed that the reliability of MTEBI was in acceptable level with the overall reliability index of 0.73 and the reliability index of self-efficacy subscales as 0.80, and the reliability index of the expected results of teaching mathematics as 0.66.
