Validity of The Abtract Algebra Teaching Book

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%)

Students’ Achievement Levels, Gender, and Learning Styles on Abstract Algebra: A Profile of Evidence Developing Ability

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

Instrument and evaluation of students’ involvement in learning Mathematics in 21-century skills at senior high schools of Riau province

Student engagement is the most crucial factor in learning activities because it is the main factor in improving student learning outcomes in class. This study aims to develop instruments and evaluate student involvement in learning mathematics to achieve maximum learning outcomes at school. The population in this study was all high school students in Riau Province. The sample is 150 high school students selected by multiple-stage random sampling based on high, medium, and low student achievement levels. Data analysis in this study was carried out four times: (1) data analysis based on the results of expert assessment of the instrument with the Aiken formula; (2) small-scale validity data analysis with first-order CFA; (3) large-scale data analysis with second-order CFA analysis; (4) descriptive analysis to see the categorization of student learning engagement in Riau Province whether in very good, good, not good and very not good. The analysis using the Aiken formula shows that 24 out of 27 items developed are valid. The first-order CFA analysis shows that the 24 items distributed are valid. The second-order analysis shows that the construct validity of the learning involvement variable is valid and reliable. The analysis of learning involvement results shows that students' involvement in learning mathematics is in the not-good category. The Riau provincial government needs to maximize student learning engagement which can be done by regulating students' effective study hours at school and home. Collaboration between parents and schools must be improved so parents can control student learning outside of school

Workshop Penyusunan Kisi-Kisi Soal Bagi Guru-Guru SMA PGRI Pekanbaru

In order to measure the achievement of students’ competencies, a teacher needs to have the skills to develop various forms of good instruments. One form of the instruments is a test with questions.
