One of the strategies to respond the formative assessment results is corrective feedback. Through corrective feedback, it can be verified and elaborated the part of each items where an error occurs which must be reviewed and corrected by students based on the signs given. The purpose of this research is to review the effect of corrective feedback on formative evaluation and mathematics self-esteem on student’s mathematics learning outcome on junior high school by controlling the prior mathematics knowledge of students. The samples were 120 seventh grade students in junior high school on first semester chosen by using random sampling. The method in this research is quasi experiment by using the design of treatment by level 2 × 2. Data were analyzed by using analysis of covariance (ANCOVA). After controlling the prior mathematics knowledge of students, in general, direct corrective feedback was more suited to increase mathematics learning outcomes on junior high school student than indirect corrective feedback. There was an interaction effect on providing corrective feedback and self-esteem on the mathematics learning outcomes. For the student who have high self-esteem, indirect corrective feedback is more suitable to increase mathematics learning outcomes while for the students who have low self-esteem, direct corrective feedback is more suitable to increase mathematics learning outcomes. It is recommended to the mathematics teachers to provide corrective feedback after provision of formative assessment in their class.

This study aimed to examine students' mathematical lateral thinking skills in creative problem-solving, differences in subjects' answers based on the level of their study period, and factors that affect students' lateral thinking skills. The descriptive method was used in the form of an educational survey. The sampling technique used in this research was stratified random sampling. The research subjects were first, third, and fifth-semester students of Mathematics Education at FKIP Tanjungpura University in 2019. The data collection technique used was the "Paper-and-pencil Assessment," with the written test sheet adopted from the Mathematical Lateral Logic Test by Bruce Woodcock. The results showed that students' lateral mathematical thinking skills in creative problem-solving were in the poor category, with an average score of 9.39 out of 25. The results of statistical tests with a value of χ2 indicated that the answers to the subjects were different based on the level of study. The ability to recognize dominant ideas and the polarization of perception of the problem, and the ability to use other ideas are the dominant factors affecting the level of students' mathematical lateral thinking skills in all subject groups. In general, the way of thinking with formal logic or thinking vertically affected students' lateral thinking patterns.

Background: This study stems from the necessity to explore the proficiency in algebraic change and relationship among sixth-semester pre-service mathematics teachers, considering they have comprehensively encountered most mathematics content subjects. Aim: The primary aim is to delineate the ability of change and relationship in algebraic material and identify common errors, thereby contributing insights to enhance the overall quality of mathematics education.Method: Employing a qualitative descriptive approach, this research involved eight students selected based on their responses to instrument questions. The instrument utilized high-level essay questions, validated with a PISA orientation and developed in alignment with the assimilation of new knowledge specific to local students. Data were analyzed descriptively using Miles and Huberman’s model.Result: Findings revealed that when confronted with PISA-level questions equivalent to junior high school level, participants exhibited difficulties, making errors in calculations, concepts, information accuracy, and in connecting or converting the given information.Conclusion: The study underscores the imperative for holistic guidance on high-level questions like PISA for aspiring mathematics teachers, serving as a catalyst for educational innovation, particularly in mathematics education.
