Abstract

The results of observations on April 15, 2019, at SMP Negeri 1 Peureulak, East Aceh District, and the 2017/2018 National Examinations showed that students experienced difficulties in geometry, so there was a need for teaching materials in the form of LAS (Student Activity Sheets). This development aims to determine that teaching materials in the form of LAS based on Acehnese local wisdom are valid, practical, and effective, and also determine student learning outcomes. This research is a development research using the ADDIE model (Analyze, Design, Development, Implementation, and Evaluation). The subject of the trial in this study was grade VII-1 students of SMP Negeri 1 Peureulak, East Aceh District. Questionnaires, observations, interviews, and tests are used as data collection techniques and instruments in this research. The data analysis in this study is descriptive analysis using the preparation/development of the LAS product variable and the resulting LAS quality variable. As for student learning outcomes in using LAS can be seen from the results of the LAS analysis, which includes student learning outcomes as one of the effectiveness aspect of LAS and test data on learning outcomes. Based on the results of the analysis, it can be concluded that the teaching materials in the form of LAS based on Acehnese local wisdom in mathematics learning especially geometry material in Junior High Schools are categorized as valid, practical, and effective. Student learning outcomes using the LAS have a mastery score with a score of 86.43.

Abstract

This research aimed to describe errors done by students in solving HOTS typed linear equation of two variables problem seen from the cognitive style in a Covid-19 pandemic era. This research uses a qualitative approach. Research subjects consist of 4 students selected among 31 students from class IX Junior High School 1 Petarukan, grouped into two students with cognitive style field-dependent (FD) and two students with cognitive style field-independent (FI). Subjects cognitive style was determined by Group Embedded Figures Test (GEFT) score, while errors in problem-solving were determined through TKPS and interviews. Field-dependent subjects tend to make errors in transformation and encoding with low or fair fallacy rate. On the other side, field-independent subjects tend to make errors in understanding the problems with low fallacy rate. The causes of errors made by field-dependent subjects are not being able to make complete mathematical models and not showing what they had searched. Meanwhile, field-independent subjects were incapable of making sketches perfectly. Other researchers' recommendation explains only errors in reading, transformation, processing capability, and encoding of students with cognitive style FD and FI. In this context, there are still a lot of other errors done by students. Therefore, the next researcher needs to conduct further research with better execution.

Abstract

The learning of addition and subtraction that usually be done in sequence impact students’ tendency to separate type of the strategies employ to solve the related problems. In fact, there are a number of situations that can be observed and solved through both lenses. Therefore, in this study we designed a simultaneous addition and subtraction of two-digit numbers learning trajectory. The learning activities were constructed based on Realistic Mathematics Education (RME) Approach. This design study was conducted in three steps consist of preliminary study, teaching experiments, and retrospective analysis. The teaching experiments were done in two cycle, the first was done with four students and the second was done with 33 students in two classes of an elementary school located in Singaraja, Bali. The data related to number sense ability were gathered from observation and students’ written work in solving worksheet and post-test. The collected data were analyzed using constant comparative method. From the results, we found that a simultaneous learning of two-digit numbers addition and subtraction were effectively develop the students’ number sense and encourage the students to develop efficient counting strategies.

Abstract

The spread of the disease that occurs throughout the world, namely the Covid-19 pandemic, has made changes to learning methods. The learning method is now carried out with online learning, which previously used the face-to-face method. However, there are many shortcomings occurred when using online learning method. One thing that is most highlighted regarding the shortcomings of online learning is the inability of students to understand the material, including learning mathematics. This study used a qualitative approach with the aim of describing the effect of giving face-to face concept reinforcement via zoom meetings on the success of online learning. The research instrument was the researcher and the interview guideline sheet. The subjects of the research are the 3rd semester students of Tadris Matematika UIN STS Jambi in the academic year of 2020/2021. The results showed that strengthening the concept via zoom meetings could be done through systematic dialogue so that the concept can be fully understood. The dialogue is an open dialogue and is very dependent on the response of students. Face-to-face strengthening of concepts in online learning through systematic dialogue via zoom meetings is proven able to make students understand the concepts being taught even though learning is done with online learning.

Abstract

This research aims to describe secondary-level students' thinking processes in terms of their attitude toward mathematics in constructing proof by mathematical induction. This qualitative research involved two students who were selected from 30 students of second grade of senior high school that categorized into two groups, namely the students who have a positive and negative attitude toward mathematics by using Attitude Toward Mathematics Inventory (ATMI) questionnaire. One student from each category was selected to be given a proving test and interviewed. Students’ process of proving test and interview recording were collected and analyzed to identify their thinking process. This research points out that both students who have positive and negative attitudes towards mathematics can recall the information in their memory regarding the characteristics and steps to prove using mathematical induction. However, the student who has negative attitudes towards mathematics tends to experience some difficulties in processing information, especially in the induction step, caused by panic, depression, and insecurity. The student who has a positive attitude towards mathematics also experiences some difficulties in the proving process, namely understanding what to prove and compiling the induction steps. However, she keeps trying and believes that she would be able to solve it. Hence, she can solve the proof completely.
