<![CDATA[The phenomenon of boarding school has evolved since the 1990s. In addition to having advantages, the school also has barriers in the learning process. Therefore, the need to explore some information directly related to the reasons why boarding school is developed, students’ life in school together and the learning process that occurred. The research method is used a qualitative approach. Schools in this study are limited to Islamic boarding schools at junior high school level in grade VII. The research procedure is undertaken to find the phenomenon of research subjects that occurred at boarding schools. The validity of data in this research uses source and method triangulation techniques, namely by checking phenomena obtained from observations, interviews with parents, interviews with students, interviews with teachers, and interviews with teachers dormitories. The general conclusion regarding Islamic-based boarding schools is that the school has become the choice of parents in educating their children to gain abilities in the religious and academic fields. In mathematics learning, the teachers prefer direct approach learning rather than indirect learning, and also most of them do not use a lesson plan as teaching guides. Therefore, the school must be able to choose and apply a learning approach oriented to the conditions of diversity that occur in boarding schools so that students have no difficulty in receiving the subject matter. ]]>

<![CDATA[This research describes the knowledge and beliefs of pre-service teachers about mathematics. Data collection of this research using written test of 143 mathematics pre-service teachers who have taken six semesters at Universitas PGRI Semarang, and interviewing of three pre-service teachers who are not consistent between knowledge and belief. The data are presented in the form of descriptive quantitative and analyzed qualitatively, including data reduction, data display, and conclusions drawing/verification. The results show that most of the knowledge of pre-service teachers are consistent with their beliefs. It is indicated that pre-service teachers’ knowledge has been internalized into a strong belief that affect their words and behaviors. The belief of almost half of pre-service teachers who become respondents changes because of lecturer activity effect. It can say that belief changes at any time, both the process of alteration and the formation of new beliefs as well as the reinforcement of the beliefs they have. ]]>

<![CDATA[The aims of this study are to (1) determine the level of mathematics anxiety (MA) of pre-service elementary school teachers, (2) compare the MA among pre-service elementary school teachers in terms of gender, and (3) compare the MA among pre-service elementary school teachers in terms of the semester. This research employed a quantitative approach with comparative research design. In addition, the samples were 498 pre-service elementary school teachers. The instrument used is the Revised-Mathematics Anxiety Survey (R-MANX) developed by Bursal and Paznokas (2006). R-MANX consists of 30 statement of a 5-point Likert scale. The data analysis was processed using one-way ANOVA assisted by SPSS version 23. The findings reveal that the MA of pre-service elementary school teachers is high. Further, it is revealed that there is no significant MA difference between male and female pre-service elementary school teachers. Also, there is no significance of MA difference among pre-service elementary school teachers who are in 2nd semester, 4th semester, and 6th semester. Therefore, the results of this research imply that MA can affect pedagogical competence of a teacher and it could have an impact on the way the teacher manages the class.]]>
