Integral calculus is a course where students tend to have difficulties in problem-solving. This study examines differences in mathematical beliefs in students' problem-solving skills based on mathematics prior knowledge. This study's subjects were 120 students of the Mathematics Education study program from UPH Faculty of Education. The independent variable is mathematical beliefs, the moderator variable is prior mathematics knowledge, and the dependent variable is students' problem-solving skills. This study is an ex post facto quantitative research with instruments in a Likert scale questionnaire for mathematical beliefs, problem-solving, and mathematics prior knowledge test scores. Hypotheses were tested statistically with a two-way Anova test using SPSS 16.0. The results of the study were: (1) students' problem-solving of logical consistency beliefs is higher than memorized and procedural beliefs, (2) there is an interaction between mathematical beliefs and mathematics prior knowledge on problem-solving, (3) students' problem-solving in high mathematics prior knowledge group of logical consistency beliefs is higher than memorized, and procedural beliefs, and (4) students' problem-solving in low mathematics prior knowledge group of logical consistency beliefs is lower than memorized and procedural beliefs.

The emergence of the Covid-19 pandemic has transformed the learning system into an online mode, where students' anxiety became the spotlight for educators to create a learning environment that actively engages them. Many educators are competing in maximizing the use of technology to ensure students are engaged in the learning process. The study aims to explore students’ perception of math anxiety through the implementation of Screencast-O-Matic in calculus learning. This study involves 41 students at the university level and is conducted in mixed methods, using statistics and narrative descriptives. Questionnaires and open-ended questions are used to investigate students’ testimonies about the video made by Screencast-O-Matic and their perceptions of math anxiety after learning with the video given. The results showed that the implementation of Screencast-O-Matic video gradually reduces students’ mathematics anxiety during online calculus learning. Screencast-O-Matic offers educators the opportunity to build a web-based lecture learning system in audio-visual media to minimize students' anxiety levels. Furthermore, the most important things to consider while creating an educational video are clarity of message, user-friendliness, good visualization, and easy access to students anytime and anywhere.

Studies that highlight the scope of mathematics learning still become continuous discussion topics. Numerous findings have the potential to be a discussion for further research. In mathematics learning, there are many problems in the form of mathematical errors made by learners in solving problems. This descriptive qualitative research aims to review mathematical errors made by students in Linear Algebra courses. Error analysis model using Kastolan stages that focus on 3 types of errors namely conceptual, procedural, and technical errors. A total of 30 students of Mathematics Education study program from Pelita Harapan University were given question to analyze their mistakes. Data analysis was performed using Miles and Huberman technique which included data collection, data presentation, and conclusion. The results showed that as many as 50% of students underwent conceptual errors, 20% of students underwent procedural errors, 3.33% of students underwent technical errors, and 26.67% of students underwent no errors. These findings provide an opportunity for researchers to analyze other mathematical learning with Kastolan stages as well as encourage researchers to develop learning models to minimize mathematical errors made by students.

The number theory is the first mathematics content course in the UPH FIP Mathematics Education study program, which does not have a response class. The response class was conducted as a companion to four content subjects with close relations with school mathematics content, namely Calculus 1, Calculus 2, Geometry, and Linear Algebra. Based on the questionnaire that has been distributed, prospective mathematics teachers consider that the response class is beneficial for them in attending lectures and in exploring related mathematical concepts. However, on the other hand, students inevitably have to go back to learning to be determined with the response class. The implication is that students' self-regulated learning will not develop optimally. However, self-regulated learning is an essential aspect that prospective teachers need to have. This research was conducted to see how self-regulated learning of future mathematics teachers in number theory courses. The research instruments used are questionnaires, the scale of self-regulated learning, and interviews. This research is a qualitative descriptive study. The results of this study are that most students have a moderate level of learning independence. The aspects or indicators of learning independence that need special attention are setting learning goals/targets. Prospective teacher students need to continue to train and develop their learning independence to become professional teachers who continue to develop along with the times.

This research aims to uncover the role of teachers in efforts to build a responsive attitude of students by using the Among system from the teaching of Ki Hajar Dewantara in online learning. This research method uses descriptive methods with a qualitative approach. The subjects in this study were students of class XI MIPA 2 which consisted of 34 students. Data collection techniques are class observation, RPP, and reflection. This research data analysis technique uses qualitative descriptive analysis by describing each phase of the system among mathematical learning in relation to students’ responsive attitude. The results of this study show that the among system is able to build a student's responsive attitude that is seen through increasing student awareness of their duties and responsibilities and active involvement in the classroom as measured through students asking questions, answering, arguing in discussions, entering classes, and doing tasks on time. This result is due to the implementation of phases in learning, namely the planning phase, the independent atmospheric phase, the among phase, the accountability phase, and the closing phase. In each phase there is a concept that is 3N, the principle of independence and family to the guidelines that are the role of teachers in the educational trilogy. In this educational trilogy, the teacher plays as: Ing ngarsa sung tuladha, Ing madya mangun karsa, and Tut wuri handayani.
