Title

Students’ Achievement Levels, Gender, and Learning Styles on Abstract Algebra: A Profile of Evidence Developing Ability Leo Adhar Effendi; Sindi Amelia
Mathematics Research and Education Journal Vol. 4 No. 1 (2020)
Publisher : UIR PRESS

Mathematics education students’ ability on developing evidence needs to be reviewed by lecturers. 50% of the subjects in the mathematics education departement require students' accuracy in analyzing mathematical statements. This is increasingly important because the Indonesian National Qualifications Framework (KKNI) for the Bachelor level requires graduates to become technicians / analysts. The diversity of levels of students’ ability, gender, and learning styles are assumsed to be the discrepancy abilities to develop evidence. This study aims to describe the evidence developing ability based on the levels of achievement, gender, and student learning styles. The subjects of this study were abstact algebra students in the mathematics education department. Type of this research was descriptive qualitative with data collection techniques using test and non-test techniques. Students were given five questions about abstact algebra that demanded the evidence developing ability. The achivement levels and gender were obtained from students’ academic achievement data. The learning styles were attained from questionnaires. The results of the study is higher the students’ academic achievement, better the evidence developing ability on Abstract Algebra. The gender does not affect the evidence developing ability on Abstact Algebra. Students with visual learning styles have the ability to develop evidence better than students with other learning styles.

Validity of The Abtract Algebra Teaching Book Sindi Amelia; Leo Adhar Effendi

Publisher : UIR PRESS

The Abstract Algebra is one of the most difficult subjects for students. In this course, students are required to have several textbooks as their reading source. However, the existing textbooks do not guide students in carrying out the process of preparing evidence and tend to speak non-Indonesian languages. The purpose of this research is to design and develop textbooks on abstract algebra courses which contain proofs in full step by step that can improve the ability to organize evidence. This type of research is development research with formative evaluation design consisting of self-evaluation, prototyping (expert reviews, one-to-one, and small groups), and field tests. The validity of the development of abstract algebra textbook is passed through the stages of self-evaluation and expert reviews. The results showed that the prototype of abstract algebra teaching books had a very high level of validity (89.29%).

This study aimed to produce learning tools based on a valid CRH type of cooperative learning model. The learning tools developed are in the form of a Learning Implementation Plan (RPP) and Student Worksheets (LKPD). The development model used in this research is the Plomp model, which is modified into four stages, namely: (1) Initial investigation, (2) Design, (3) Realization/construction, (4) Test, evaluation, and revision. The data analysis technique used is descriptive statistical analysis. From the research results, the average total validation of the RPP is 88.67%, with very valid criteria. This means that the RPP made by the researcher is suitable for use or trial. Then, the average total validation of LKPD is 84.98%, with quite valid criteria. This means that the LKPD made by the researcher is feasible to use but requires a small revision. Based on the results of these studies, it can be concluded that the development of learning tools based on the CRH type cooperative model on the material of compositional and inverse functions whose validity has been tested is feasible to use

This research is motivated by the need for evaluation instruments because at SMKN 3 Pekanbaru does not hold school exams so that student assessments are taken from daily exercises at the end of learning. This study aims to determine the validity, practicality and learning outcomes of students using wordwall-based evaluation instruments. This type of development research uses the R&D (Reasearch and Development) model which has been modified into 8 stages, namely potential problems, data collection, product design, design validation, design revision, product trials, product revision and trial use. The data collection techniques used in this study were validation sheets, student and teacher response sheets and student learning outcomes tests using wordwall-based evaluation instruments. The research subjects were E phase students of SMKN 3 Pekanbaru. The results of the wordwall-based evaluation instrument validation test were 88.29% with a very valid category. The results of the practicality test of wordwall-based evaluation instruments based on teacher and learner response sheets were 91.75% with a very practical category. The learning outcomes of students using wordwall-based evaluation instruments were 92.59% with a very good category.
