This study aims to determine the factors that influence academic achievement and student study period. The method used in this research is ex-post facto qualitative research, with a comparative model that compares several similar variables. The sample involved was 398 students from five State Islamic Universities in Central Java. Samples were selected using the random sampling method. Data collection techniques used are observation and documentation. The data obtained were analyzed using one-way ANOVA and multiple linear regression. The results showed that: (a) Only two of the six factors had a significant effect on student achievement, that was gender and the new student’s admission way. (b) There were four of the seven factors that significantly affected the study period, that was gender, type of high school, GPA, and PMB wayway. (c) There was a significant difference in student achievement in terms of the new student’s admission way. The highest academic achievement (GPA) was achieved by students who are accepted through the National Academic Achievement Selection Wayway of State Islamic Religious Colleges with an average of 3.61. d) There was a significant difference in the study period in terms of the wayway for new students. The fastest study period was reached by students who were accepted through the State Islamic Religious College Entrance Examination way with an average of 8.5 semesters. (e) There was a very significant negative correlation (sig. = 0,000) between the GPA and the study period, which means that the higher the student GPA, the faster the study period.

Mathematics is an important field of study that is taught at various levels, one of them is college. To become a Bachelor of Mathematics Education, one of students' mathematics skills can be seen in the ability to solve problems. This study aimed to find out the error of Mathematics Education students in solving Differential Equation problems based on Watson's criteria, and find out the factors causing the error to occur. This research is important to do to find out the errors in solving Differential Equation problems and the factors causing the error to occur. The research design and approach of this research was Descriptive Qualitative. Data was obtained through written test instruments, interviews and documentation. The analysis technique used to analyze student error was based on Watson's 8 criteria, while the research data analysis were data reduction, data presentation and drawing conclusion. The results found that the percentageof inappropiate data (28.11%), inappropiate procedure (24.32%), omitted data (27.57%%), omitted conclusion (84.86%), response level conflict(2.16%%), undirected manipulation (4.86%), skill hierarchy problems (6.49%), and above others (64.32%). The percentage of error that occurred in 37 students from all questions based on Watson's 8 criteria was 30.34%. Factors that cause errors are: (1) internal factors,students do not fully remember the material being tested, they have not mastered the material tested properly and are not thorough when doing the test; (2) external factors, students do not focus when doing the test, work together with friends, and incomplete notes.Keywords: Error Analysis, Cause Factors, Watson Categories, Differential Equations.

Mathematics is a discipline that can improve thinking skills. However, in reality, the mathematics thinking skills of elementary school students are still low. This is because the mathematics learning used is not optimal and still uses conventional learning. In the process of mathematics learning, there is an integration of character values with mathematics material. Character building through mathematics learning has not been done relatively. The current mathematical concept can be related to cultural activities called ethnomathematics. Through ethnomathematics, mathematics learning becomes more realistic. The purpose of this research is to build students’ character and improve student’s mathematic learning achievement through developing student worksheets with a mathematical approach based on ethnomathematics. The methods of the research were research and development by using steps including preliminary study, design, development, and dissemination. The result of the research is student's worksheets fulfill valid, practical, and effective criteria. The result of the validity of teaching media shows that the average number is 96 % with very good criteria. The effectiveness test shows that there is a distinction of student’s achievement before and after the treatment and the student’s achievement on average is increased. Based on the analysis of student's answers on student worksheets, four characters are built through the learning process with a realistic mathematic approach based on ethnomathematics, such as creativity, independence, curiosity, and nationality. Keywords: character building, realistic mathematics learning, ethnomathematics.

This research aims to evaluate the effect of implementing differentiated learning using the Open-Ended Problem Based Learning model on students' computational thinking abilities at the Batang State Tsanawiyah Madrasah. The research used mixed methods with a concurrent embedded model, which combines quantitative and qualitative approaches. Data was collected through computational thinking ability tests, interviews, and observations during the research period. The research results show a significant increase in students' computational thinking abilities after implementing differentiated learning. Quantitative data analysis shows significant differences between before and after learning, with visible improvements in aspects of computational thinking capabilities such as abstraction, algorithms, decomposition, and pattern recognition. These findings show that differentiated learning using the Open-Ended Problem Based Learning model can improve students' abilities in computational thinking and solving problems effectively.
