Abstract

Algebraic thinking is an important element in mathematics thinking and reasoning. All students experience a transition to algebraic thinking. It happens from elementary school grade V until junior high school grade VII. This study aims to describe the differences in algebraic thinking ability from the beginning of transition period, elementary school grade V, until the end of the transition period, junior high school grade VII. This research was a cross-sectional research using mixed method approach. The results showed that students' algebraic thinking ability at the beginning of the transition period and at the end of the transition period was in moderate criteria. The average score in algebraic thinking test at the end of the transition period, junior high school grade VII, was higher than the students in junior high school grade V, but the algebraic thinking ability of students in elementary school grade V did not have much different with the students of junior high school grade VII, that was in the moderate criteria.

Abstract

This research aimed to describe: 1) the effectiveness of the use of Problem Posing Learning by CTL orientation, 2) the effectiveness of the use of CTL lessons viewed from knowledge, skills, and students’ attitude, and 3) to compare which one is more effective between Problem Posing Learning by CTL orientation and CTL lessons viewed from knowledge, skills, and students’ attitude. The kind of this research was quasi experiment by using pretest-posttest control group design. The population of this research was the eleventh grade students of MA NW Pancor, Lombok Timur, NTB. The sample of this research was already chosen randomly. Techniques of collecting the data were test and non-test by using research instrument of knowledge test, skills test, and students’ attitude questionnaires. One sample t-test used to test the effectiveness of learning which was already used in each variable. The result of the research showed that: 1) Problem Posing Learning by CTL orientation was effective viewed from knowledge, skills and attitude students’ attitude, 2) CTL was effective viewed from knowledge, skills, and students’ attitude, and 3) there was no effectiveness difference between Problem Posing Learning by CTL orientation and CTL lessons viewed from knowledge, skills, and students’ attitude.

Abstract

This study aims to produce a mathematics enrichment book to facilitate problem-solving ability based on the aspects of validity, practicality, and effectiveness. The research method used is research and development using the ADDIE model which includes the analysis, design, development, implementation, and evaluation stages. The research instruments used consisted of validation sheets, practicality assessment sheets, and test questions for mathematical problem-solving abilities. Validity and practicality data analysis was carried out by converting the total score of quantitative data obtained into five-scale qualitative data. Effectiveness of data analysis is done by determining the percentage of the number of accomplished students and the average test scores of mathematical problem-solving ability. The result of the research is a valid, practical, and effective mathematics enrichment book to facilitate problem-solving ability. The mathematics enrichment book developed has met validity criteria based on the validators’ assessment with the average score in the high category, fulfills the practicality criteria based on the teachers’ assessment with the excellent category, and meets the effective criteria based on the results of the mathematical problem-solving ability with the percentage of students accomplishment of 79.5% and the average score of the test results of 79.

Abstract

Link and match antara sektor pendidikan dan dunia usaha dan dunia industri (DUDI) juga menjadi tuntutan untuk menghasilkan lulusan SMK yang berdaya saing global. Untuk mewujudkan ekosistem pendidikan vokasi yang  tepat dan berkelanjutan, salah satu langkah strategis yang dapat ditempuh adalah penguatan kompetensi guru dalam mengintegrasikan dunia usaha dalam pembelajaran berbasis proyek (PjBL). Implementasi kurikulum merdeka menuntut guru dapat menyelenggarakan PjBL untuk dapat meningkatkan kolaborasi dan kemandirian peserta didik, serta mendukung terbentuknya lulusan dengan hardskills, softskills dan karakter yang kuat. Namun, dalam pembelajaran di SMK, integrasi Lembar Kerja Peserta Didik (LKPD) yang mendukung implementasi PjBL belum dilakukan dengan optimal. Kegiatan ini berupaya mengoptimalkan kompetensi guru dalam penyusunan LKPD beorientasi PjBL. Tidak hanya mendukung kompetensi guru, kegiatan ini diharapkan dapat menjadi inovasi dalam pembelajaran dan menjadikan pembelajaran lebih aplikatif. Kegiatan dilakukan dalam bentuk pelatihan dan pendampingan dalam penyusunan LKPD berorentasi PjBL secara luring dan asinkronus. Kegiatan dibagi menjadi dua sesi, yakni sosialisasi model PjBL dan pemanfaatan LKPD berorientasi PjBL, dan sesi kedua berupa peningkatan kompetensi guru dalam penyusunan LKPD berorientasi PjBL. Sesi pertama dilakukan secara luring melalui sosialisasi dan pelatihan, sedangkan sesi kedua dilakukan secara asinkronus dalam penyusunan LKPD berorientasi PjBL sesuai mata pelajaran masing-masing. Pada akhir kegiatan ini, 98.39% guru SMK menyatakan berminat dan siap mengimplementasikan PjBL dalam pembelajarannya.
