Abstract

This research is based on the results of a preliminary study which identified students' learning barriers in algebraic multiplication and division material in elementary schools. Students do not fully understand the concept of algebraic multiplication and division due to learning obstacles related to limited didactic designs made by teachers. Learning obstacles experienced by students must be anticipated through a learning process that is able to overcome these problems. The researcher developed a didactic learning design using a Realistic Mathematics Education (PMR) approach. The aim of this research is to determine the learning obstacles experienced by students, develop didactical designs for algebraic multiplication and division, describe, test, and describe the designs that have been created. The research method used in this research is Didactical Design Research (DDR). This method consists of three stages, namely didactic situation analysis before learning in the form of Hypothetical Learning Trajectory (HLT) and Pedagogical Didactic Anticipation (ADP), metapedadidactic analysis and retrospective analysis. The data collection technique used is triangulation which combines observation, interviews and documentation. The design development process was carried out in class V with a total of 18 students, and the preliminary study stage was carried out in class IV at SDN 1 Sukamanah with a total of 22 students, and class IV at SDN Sukamulya with a total of 16 students. This research produces data regarding student barriers to multiplication and division material, didactical design in the form of teaching materials, student worksheets (LKPD), to minimize students' learning barriers to multiplication and division material in algebra.

Abstract

This study aims to determine the effectiveness of the STAD cooperative learning model in terms of students' self-efficacy towards mathematics learning outcomes, particularly in the topics of Least Common Multiple (KPK) and Greatest Common Divisor (FPB), for fourth-grade students at SD Negeri Manyaran 02, divided into two learning groups: Class IV.A with 25 students and Class IV.B with 24 students. The research design employed in this study is quasi-experimental. Quasi-experimental research is conducted under conditions that do not allow for full control. Data collection utilized questionnaire and test techniques, followed by data analysis using a two-way ANOVA and further post hoc tests (multiple comparisons). Based on the tests, the test instrument was declared valid, with difficulty index reaching ???? < 0.30 for difficult criteria and ???? > 0.70 for easy criteria, as well as a reliability index of ????11 > 0.70. The study findings indicate that there is no significant effect of the STAD cooperative learning model on mathematics learning outcomes when viewed from the self-efficacy of fourth-grade students. However, the relationship between the STAD model and self-efficacy in mathematics learning outcomes shows positive results. Students with higher self-efficacy indices are proven to have better learning outcomes compared to those with lower self-efficacy levels.

Abstract

The students have difference in cognitive style. This research aimed to describe and analyze students’ communication skills and creative thinking skill level in view of field dependent and independent cognitive style on algebraic concept. Algebra communication skill is essential skill needed for solving mathematical problems. Algebra must be mastered by the students because related to other materials. Algebra topic analyzed in this study is quadratic equation word problems. The indicators of communication skill include (1) able to state the situation into mathematical notations, structures or symbols, (2) able to demonstrate and describe unique algorithms in problem solving, and 3) able to construct and explain real-world phenomena in graph, sentence, equation, table or other presentation. The student level of creative thinking skill can be seen from fluency, flexibility and novelty. This research used a mixed-method. The object were 16 students of junior high school in Tangerang. The data collection techniques used test and interview. Cognitive styles are grouped using the Group Embedded Figure Test (GEFT) which divide the students into field dependent (FD) and field independent (FI). The results of the study indicated that algebra communication skill of students with FD and FI were not different significantly in problem solving. Both are able to understand the problems into mathematical expressions, but not all groups state the correct mathematical equations. The students used different strategy to solve the problems. FD students used less detailed strategy, incomplete analysis, think generally, and not quite precise in writing mathematical equations, while FI students provided detailed explanations, better accuracy, think more flexibly, and state mathematical equation precisely. In general, they have same creative level.
