STEM education at junior high school mathematics course for improving the mathematical critical thinking skills

Abstract

The development of learning models based on integrated STEM lower secondary education projects has not yet been carried out. The integration of STEM into education is necessary because the high demand for human resources in 21st century STEM mastery-based learning provides space for students to choose activities to be carried out during learning, it also presents great opportunities for teachers to observe activity in developing student abilities. Quantitatively, an integrated project-based STEM learning model can improve students' critical thinking skills in mathematics in junior high school.In this regard, this study aims to develop project-based teaching materials that present mathematical topics combined with other STEM field teachers. The research method used is research and development. In this study only carried out at the stage of testing the validity of teaching materials that have been developed. Data collected during the study are material content validity evaluation sheets, advance validity, and construct validity, as well as conclusions on the feasibility of teaching materials. The data obtained were tested using Q-Cochran. The results showed that the integrated Project-Based Learning STEM teaching materials had passed the pace of development, an examination by judicial experts, and expert media testing to validate teaching materials. The validation results show that the face validity and the content validity of the teaching materials are valid and feasible. Then the results of construct validity are included in the validity of very good to very good. Then the validity of each item on the evaluation shows the high validity of the dominant values. It can be concluded from this study that the teaching materials developed have high flexibility, the instructions contained in the teaching materials are easily understood by students, and are suitable for use in a limited scope.

Mathematical Modeling and Simulation of Online Teaching Effect Evaluation Based on Decision Tree Algorithm

“…Teaching effect evaluation is one of the links of teaching quality management and supervision, which can ensure the effectiveness of teaching methods [6]. Whether the teaching effect is perfect needs to be further reflected in the evaluation indicators [7].…”

Efektivitas LKS Berbasis Etnomatematika dengan Pendekatan STEM terhadap Kemampuan Berpikir Kritis

“…Berpikir kritis menjadi salah satu kemampuan penting yang harus siswa miliki selain kemampuan memecahkan masalah matematika (Priatna et al, 2020;Saputra, 2020). Kemampuan berpikir kritis berguna untuk pembuatan keputusan, menganalisis masalah, dan pemecahan masalah yang diterapkan dalam kehidupan.…”

Pedesaan Pengembangan Model Project-Based Learning Terintegrasi STEM untuk Meningkatkan Kemampuan Berpikir Kritis Matematis Siswa SMP

“…Dalam pembelajaran matematika tidak semua topik pembelajaran dapat menggunakan teknologi, menjadi tantangan untuk mengemas pembelajaran matematika dengan berbasis project dan melibatkan STEM seperti yang diungkapkan oleh Priatna et al (2020) pembelajaran berbasis project lebih umum digunakan pada pembelajaran sains dari pada pembelajaran matematika, sehingga menjadi tantangan untuk menggunakan pembelajaran berbasis project pada pada topik-topik matematika. Owens & Hite (2020) pembelajaran PjBL dengan STEM dan berkolaborasi melaksankan pembelajaran secara virtual pada beberapa negara yang dapat meningkatkan kemampuan matematis yaitu kemampuan komunkasi matematis siswa.…”

“…PjBL termasuk ke dalam salah satu model yang disarankan dalam kurikulum 2013 untuk digunakan selama proses pembelajaran. Model pembelajaran harus melibatkan pengalaman siswa, sehingga siswa dilatih untuk berpikir kritis dan mampu mengemukakan gagasan melalui aktivitas berbasis project, seperti yang diungkapkan oleh Priatna et al (2020) pembelajaran berbasis proyek dinilai mampu meningkatkan kemampuan memecahkan masalah matematika, meningkatkan kemampuan berpikir siswa, dan minat siswa. Bukan hanya PjBL, integrasi STEM dalam pembelajaran di sekolah-sekolah Indonesia belum gencar dilakukan.…”
