Abstract

Penelitian ini bertujuan mengetahui prestasi mahasiswa penggunaan strategi pembelajaran aktif tipe the power of two pada mata kuliah microteaching Tahun akademik 2017/2018.Sampel dalam penelitian ini diambil dengan menggunakan teknik  Cluster Random Sampling yaitu pada penelitian ini adalah mahasiswasemesterVIIA sebagai kelas eksperimen dan VIIB  sebagai kelas kontrol  dan jumlah setiap semester adalah 30 mahasiswa. Jenis penelitian yang digunakan pada penelitian ini adalah quasi eksperimen (eksperimen semu) dan  menggunakan tes yang berbentuk  uraian 5  soal. Dari hasil perhitungan pretes dan protes, data tersebut  diuji kedalam pengujian normalitas dan homogenitas dari kedua kelas, dinyatakan berdistribusi normal  dan homogen. Selanjutnya dilakukan pengujian hipotesis diperoleh    thitung = 4,53 dan ttabel = 2,002 dengan dk = 30 + 30 – 2 = 58 dan a = 0,05 maka thitung>  ttabel yaitu 4,53 > 2,002, sehingga hipotesis nol ditolak,sekaligus menerima hipotesis alternatif. Sehingga dapat disimpulkan bahwa adapengaruh strategi pembelajaran aktif  tipe The Power Of Two terhadap prestasi akademik mahasiswa pada mata kuliah microteaching.

Abstract

The research aims to develop a valid, practical, and effective Think Talk Write (TTW)-based e-LKPD assisted by the Liveworksheets application to improve students' mathematical communication skills in trigonometry. The research is motivated by students' low mathematical communication skills in conveying mathematical ideas, using symbols and notation appropriately, and presenting mathematical representations in problem solving. This study uses the Research and Development (R&D) method with a 4D development model consisting of the Define, Design, Develop, and Disseminate stages. The research subjects are 33 students at Xth-2 class of SMK SMK Swasta Al-Ma'shum Sidodadi. The research instruments consisted of a validation sheet, a teacher and student response questionnaire, and a mathematical communication skills test. The results showed that the developed e-LKPD met the criteria for validity based on the validator's assessment, practicality based on teacher and student responses, and effectiveness with a classical completion rate of 82%. Thus, the TTW-based e-LKPD assisted by Liveworksheets is suitable for use in mathematics learning to help improve students' mathematical communication skills.

Abstract

This study aims to create innovation in LKPD through the development of LKPD using the PjBL model assisted by the Assemblr Edu application. The 4D development model which includes: (1) definition, (2) design, (3) development, and (4) dissemination. The subjects of this are Xth class students of SMAN 1 Tanjung Tiram. The LKPD validation sheet, ability test, teacher and student response surveys, and learning activity observation sheet are some of the research tools used. The validation test is carried out by 3 validators, the practicality test is carried out by teachers, and 36 experimental students are used to evaluate the feasibility of LKPD, while the effectiveness test is carried out by 36 experimental class students and 36 control classes. Considering the findings of the data analysis, the LKPD validity test obtained a validity percentage of 88%, categorized as "very valid". Thus, the LKPD made is considered valid. Due to the test of student responses, 85% of respondents were classified as "practical", and the findings of the teacher response analysis resulted in a classification 83% as “practical". Meanwhile, 83% of the ability test results fell into the "effective" category, and the "very effective" category with an average percentage of 94% in the activity observation analysis results. Therefore, the LKPD with the help of the Assemblr Edu application can be used at Xth Class Students of SMA Negeri 1 Tanjung Tiram in 2024/2025 Academic Year. Keywords: Student worksheets, PjBL model, Concept understanding
