Abstract

Tujuan penelitian ini adalah mengetahui: (1) validitas produk berupa tes pengetahuan hakikat sains, (2) karakteristik tes pengetahuan hakikat sains. Populasi dalam penelitian ini adalah keseluruhan siswa SMP Negeri 3 Talang. Sampel dalam penelitian ini adalah kelas VIII tahun ajaran 2022/2023 SMP Negeri 3 Talang. Penelitian ini menggunakan model ADDIE yang dibatasi hanya sampai tahap Development. Teknik pengumpulan data dengan metode wawancara, tes, dan angket. Butir-butir tes pengetahuan hakikat sains telah memenuhi validitas ditinjau dari aspek isi, aspek psikometri, dan aspek konstrak. Validasi aspek konstrak memberikan hasil: (a) item fit tes pengetahuan hakikat sains dinyatakan fit atau dapat berfungsi dengan baik, (b) person fit menghasilkan sebanyak 100 respon peserta tes dikatakan fit atau sesuai dengan model, (c) tes pengetahuan hakikat sains bersifat unidimensi. Karakteristik butir soal dilihat dari tingkat kesukaran butir tes dengan hasil 30 % soal mudah, 60 % soal sedang, dan 10% soal sukar.

Abstract

The purpose of this study is to determine the application of the Problem Based Learning (PBL) learning model affects the ability in learning chemistry in high school. The research was conducted through a literature review from various reliable sources published in 2020-2024. Compared to the traditional learning model, the application of PBL improves students' argumentation skills consistently. This improvement can be seen from the increase in post-test mean scores, N-Gain scores, and mastery of argumentation metrics such as claims, justifications, and refutations. In addition, the PBL model showed better results when used together with learning media, STEM approaches, or group discussions. Therefore, PBL helps students in problem-solving, critical thinking, and scientific communication skills in chemistry learning.

Abstract

Students are required to be flexible and responsive learners in the midst of uncertainty and changes in global situations. Learning agility in college students allows new students to adapt and create new values when they are in ambiguous situations. Therefore, a valid learning agility instrument is needed so that the adaptation of the measuring instrument to the instrument proposed by Gravett and Caldwell (2016) is carried out to test the learning agility measuring instrument for new students by implying four dimensions, namely people agility, change agility, results agility, and mental agility. The participants of this study were 222 new students of the Faculty of Psychology, Syarif Hidayatullah Islamic State University Jakarta. Confirmatory Factor Analysis (CFA) was used as a data processing method with the help of Lisrel 8.80 software. Based on CFA analysis, it can be concluded that there are two items dropped because they are not significant in measuring the dimensions of learning agility. Keywords : learning agility, CFA, adaptation, learning
