This research is motivated by the low ability to understand mathematical concepts possessed by prospective elementary school teacher students. This study aims to see the achievement and improvement of students' mathematical understanding abilities that use Microsoft Excel-based VBA teaching materials with those using conventional learning. This study uses a quasi-experimental method with a non-equivalent pre-test and post-test control group design. This study's population were all second-semester elementary school teacher candidates in one private university in West Java, Indonesia. The sample in this study was 70 prospective 2nd-grade elementary school teacher candidates. The instrument used in this study was a test of understanding mathematical concepts. The results showed: 1) learning using VBA Microsoft Excel as a teaching material was able to improve students' ability to understand mathematical concepts; 2) learning using Microsoft Excel VBA as teaching material is better than conventional learning; and 3) students can be enthusiastic, active and motivated in learning mathematics with VBA Microsoft Excel.
The purpose of this study is to analyze the role of mathematics realistic education (RME) approach on students’ mathematical critical thinking and resiliency. This study is an experiment with pre test-post test control group design and involves 62 eleventh grade students, a mathematical critical thinking test, a mathematical resiliency scale, and a perception on RME approach scale. The study found, on mathematical critical thinking ability (MCTA), its N Gain, and mathematical resiliency (MR) students getting treatment with RME approach attained better grades than the grades of students taught by conventional teaching. The first group students attained at medium grade level on MCTA and fairly good grade level on MR, while the second group students obtained at low grade level on MCTA, medium grade level on MR, and they realized difficulties in some items of mathematical critical thinking tasks. The other findings, there was no association between MCTA and MR, and students learned actively, thought critically and creatively, were unafraid to pose their opinion and performed to be self confident during RME approach.
The background of this research is that thinking skills and awareness of the importance of mathematics need to be taught and trained to students from an early age because in everyday life many things are related to thinking skills and awareness of the importance of mathematics. The purpose of this study was to determine the effectiveness of teaching materials using the RME approach in the perspective of elementary school students' multiple intelligences. The method used is descriptive qualitative research with the study population is all elementary schools in the city of Cimahi. The instruments used in this study were written tests, observation, and documentation which were carried out at the pretest and posttest stages. The results of the research achieved were an increase in thinking skills and awareness of elementary students in learning mathematics and the availability of teaching materials using the RME approach.

Certification means to improve the quality of teacher competence. Certification allowances still raise questions about low teacher competency and student learning achievement. Based on this, a study was conducted on the effect of certification (x) benefits on teacher competency (y) and their implications for student learning achievement (z). The research aims: 1) Effect of certification benefits on teacher competence. 2) Effect of teacher competence on student learning achievement. 3) Efforts need to be made to improve teacher competency and student learning achievement. Research uses descriptive methods with quantitative approache. The sampling technique used is saturated sampling technique. The sample consisted of 33 teachers. Samples were selected with nonprobability sampling technique. Data collection using questionnaires, interviews, and student test results. Validity test using product moment formula, and reliability testing using the alpha coefficient formula. Data analysis techniques used product moment correlation, path analysis and t test with SPSS version 21. Research results: 1) Teacher certification allowance (x) has a positive effect on teacher competence (y). This is evidenced by the results of the correlation coefficient (r) of 0.586 and the strength of the influence of 0.443. 2) Teacher competency (y) has a positive effect on student learning achievement (z). This is proven by the results of the correlation coefficient (r) is 0.708 and the power of influence is 0.501
