Abstract

Instrumen penilaian yang berkualitas diperlukan untuk mengukur hasil belajar peserta didik secara akurat dan dapat dipertanggungjawabkan. Penelitian ini bertujuan menguji secara empiris kualitas achievement test pada materi sistem peredaran darah dalam pembelajaran IPA terintegrasi Augmented Reality. Uji empiris dilakukan pada satu kelas dengan jumlah peserta didik sesuai kondisi lapangan. Sebanyak 50 butir soal dianalisis menggunakan SPSS untuk mengetahui validitas, reliabilitas, tingkat kesukaran, dan daya pembeda. Hasil analisis menunjukkan bahwa sebagian besar butir soal memiliki nilai korelasi di atas r-tabel dan reliabilitas KR-20 berada pada kategori tinggi. Mayoritas butir juga berada pada tingkat kesukaran sedang serta memiliki daya pembeda yang baik. Dengan demikian, achievement test yang dikembangkan dinyatakan layak digunakan sebagai instrumen evaluasi pembelajaran IPA. Instrumen ini diharapkan dapat mendukung evaluasi pembelajaran berbasis teknologi serta menjadi acuan dalam penelitian lanjutan terkait pembelajaran IPA terintegrasi AR.

Abstract

This study aimed to investigate the influence of the Student Teams Achievement Division (STAD) cooperative learning model supported by Mocheclay media on students’ conceptual understanding in science. A quasi-experimental method was employed, utilizing a non-equivalent group design. Participants were selected through purposive sampling, with class VIII F (30 students) assigned as the experimental group taught using the STAD model assisted by Mocheclay, and class VIII H (30 students) as the control group taught through direct instruction. The calculated effect size was 1.23, indicating a strong influence of the STAD model supported by Mocheclay media on students’ scientific conceptual understanding. The experimental group's normalized gain score reached 64%, whereas the control group achieved only 33%. Independent sample t-test results revealed a significant difference in conceptual understanding between students exposed to the STAD-Mocheclay approach and those taught with direct instruction.

Abstract

Initial conditions of plant anatomy practical learning at Wiralodra University indicate a lack of training in students' kinesthetic bodily intelligence. This is evident as students do not feel proficient in operating microscopes and determining microscope magnification, indicating a lack of trained kinesthetic bodily intelligence. Based on this issue, a digital microscope is needed to train students' kinesthetic bodily intelligence in plant anatomy practicals. The innovation of digital microscope technology is necessary as a supporting tool for plant anatomy practicals. The objective of this study is to develop an Online Microscope Viewer to enhance students' multiple intelligences in plant anatomy practicals. Considering the nature of the study as the development of an Online Microscope Viewer, the research design used is Research and Development. The study subjects consist of 185 second-semester biology education students from the Biology Education program at Wiralodra University, divided into five classes. The sampling method used is cluster random sampling, with two classes, Bio B (experimental group) and Bio D (control group), selected under the condition that the populations are homogeneous. The results indicate that the developed Online Microscope Viewer used in plant anatomy practicals is highly valid. The developed Online Microscope Viewer can significantly enhance students' kinesthetic bodily intelligence in plant anatomy practicals, categorized as high. There is a significant difference in the improvement of students' kinesthetic bodily intelligence between the class using the Online Microscope Viewer and the class using binocular light microscopes.
