This study confirms the correlation model constructed among organizational abilities variables of secondary school teachers. The organizational abilities variables are: organizational commitment, and professional commitment, job satisfaction, and job performance. The samples are secondary school teachers selected using purposive sampling techniques. Data were collected through a rating scale questionnaire (1-5) and analyzed using Lisrel 8.0 program. The results show that professional commitment has a significant effect on organizational commitment and job satisfaction with values of 2.72 and 2.60. Other findings that organizational commitment and job satisfaction have an effect on job performance with values of 2.36 and 2.02. Empirically, the results concluded that the correlation among the variables theoretically fulfilled the fit criteria.

Teachers’ diagnostic practice on students-difficulties is one of the important steps in designing and managing classroom lessons. The purpose of this study was to explore teachers’ perception and practices regarding diagnosing students’ learning difficulties. The participants of the study were 28 Indonesian mathematics teachers of Junior High School. The data was collected through a Focus Group Discussion and a teacher questionnaire. The data were analyzed qualitatively to describe how the teachers perceive learning difficulties and how the teachers diagnosed students’ learning difficulties. The results of the analysis reveal that the teachers do not yet perform an in-depth diagnosis of students’ difficulties in learning mathematics. The teachers only focus on the mathematics topics and non-mathematical issues, instead of on students’ thinking process. The teachers also do not differentiate the diagnosis, evaluation, and prediction test. With regard to the strategies used by the teachers to diagnose students’ difficulties, analyzing students’ responses to tests was the majority. In this respect, observing students’ learning process during classroom activities is rarely done by the teachers in the purpose of diagnosing students’ learning difficulties. The results of the diagnosis are mainly used as the basis for remedial and drill and practices. The results imply that more support is needed for teachers to improve their competences particularly in diagnosing students’ thinking process difficulties when learning mathematics.

This quasi-experimental study aims to determine the impact of realistic mathematics education (RME) on increasing Mathematical Problem-Solving Abilities (MPSA). The research design used was the non-equivalent control group with the subject population of all junior high school students in the city of Yogyakarta originating from low (C), moderate (B), and high (A) levels. From each school level, one school was taken then from each school taken an experimental class that received RME and one class of control who received regular learning (PB). The instrument used is in the form of two sets of equivalent MPSA tests. Data analysis uses the t-test and Anava. The results of the research were: (1) an increase in the MPSA of RME students was higher than the increase in the MPSA of PB students for all students and all levels of the school; (2) the highest increase in MPSA for RME students occurs at level A schools; and (3) there is no interaction between learning at school level in increasing MPSA.

The purpose of this study is to develop a scale to measure honesty characters of students on mathematics learning using sucject scaling model. This development research is carried out in several steps namely: preparing initial scales, trials, and interpretation of trials result. The research is conducted on students of SMP N 5 Yogyakarta, SMP Muhammadiyah 2 Yogyakarta, and SMPIT Abu Bakar Yogyakarta. The first trial involves 688 students and the second trial involves 696 students. Content validity is obtained through expert judgment. The construct validity is determined by Lisrel’s second order CFA. Reliability coefficients include Omega coefficients (ω) and Alpha coefficients from Cronbach. Based on the results of this research, the scale to measure of student’s honesty characters consists of 15 items that theoretically and empirically proved to be of good quality. The scale has good content validity supported by V Aiken index of 0.88-0.92. The scale has good construct validity. Reliability of the scale is also good supported by both the Omega coefficient of 0.86.

The purpose of this study was to see how self-efficacy of students towards the learning process online amid the Covid-19 outbreak. This research is a descriptive study that describes self-efficacy based on the dimensions that exist in self-efficacy and is summarized and used as a measurement tool or instrument, namely the level (magnitude) associated with task difficulties, strength related to the effort made by students, and energy-related to space. the scope of student beliefs. The instrument used was a non-test in the form of a questionnaire self-efficacy consisting of 30 statements with 4 choices and 616 respondents. The result is that the dimensions of the level of Indonesian SMP / MTs students are in the medium category with a percentage of 55.04%, which means that when students are faced with difficult tasks during learning online, students can overcome them. The dimension strength is in the medium category with a percentage of 56.82%, this shows that the efforts and resilience of Indonesian SMP / MTs students in doing assignments in learning are online quite persistent and do not give up easily. The dimension generality is in the medium category with a percentage of 45.94%, which means that Indonesian SMP / MTs students' confidence in completing different tasks is quite good. In general, the self-efficacy of Indonesian SMP / MTs students in learning online is quite good.
