Abstract

Low enthusiasm and student learning outcomes during the online learning process are influenced by several factors, one of which is the self-efficacy factor. The reality on the ground shows that teachers have not been able to measure students' self-efficacy level during the online learning process, so this research was conducted to develop and validate items that assess four sources of self-efficacy in online learning. This research belongs to the type of development research carried out through the literature review stage, deriving instrument items, testing instruments on samples, selecting instrument items, and analyzing the reliability and validity of the instrument. The subjects involved in this research were one expert in educational evaluation, one in online learning, and 176 students. Data collection in the study was carried out using the non-test method, with research instruments in the form of instrument validity sheets and student self-efficacy questionnaires. The data obtained in the study were then analyzed by testing the validity and reliability of the instrument items using partial least squares (PLS) analysis. The research analysis results show that the instrument developed has achieved valid and reliable values for thirteen items on self-efficacy measurement in online learning, so this instrument can be used in research involving self-efficacy as a variable that has shown four sources/dimensions of self-efficacy.

Abstract

Pembelajaran matematika di sekolah dasar sering menghadapi kendala berupa rendahnya aktivitas belajar siswa dan kurang optimalnya kemampuan pemahaman konsep matematis. Salah satu alternatif solusi adalah penggunaan model pembelajaran Guided Discovery yang dipadukan dengan media PhET Arithmetic untuk menciptakan pembelajaran yang lebih interaktif dan bermakna. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan model pembelajaran Guided Discovery berbantuan PhET Arithmetic terhadap aktivitas belajar dan kemampuan pemahaman konsep matematis siswa sekolah dasar. Metode penelitian yang digunakan adalah kuantitatif dengan desain kuasi eksperimen Nonequivalent Control Group Design. Sampel penelitian berjumlah 172 siswa kelas IV yang dibagi menjadi dua kelompok, yaitu kelompok eksperimen dan kelompok kontrol, masing-masing 86 siswa. Instrumen yang digunakan berupa lembar observasi aktivitas belajar dan tes pemahaman konsep. Analisis data dilakukan melalui uji normalitas, homogenitas, paired sample t-test, independent sample t-test, dan MANOVA. Hasil penelitian menunjukkan bahwa penggunaan model pembelajaran Guided Discovery berbantuan PhET Arithmetic berpengaruh signifikan terhadap aktivitas belajar dengan peningkatan rata-rata 15,105 dan perbedaan posttest sebesar 9,198 (Sig. = 0,000 < 0,05). Selain itu, terdapat pengaruh signifikan terhadap kemampuan pemahaman konsep matematis dengan peningkatan rata-rata 53,477 dan perbedaan posttest sebesar 28,965 (Sig. = 0,000 < 0,05). Secara simultan, hasil uji MANOVA juga menunjukkan pengaruh yang signifikan (Sig. = 0,000 < 0,05). Dengan demikian, model pembelajaran Guided Discovery berbantuan PhET Arithmetic efektif dalam meningkatkan aktivitas belajar dan kemampuan pemahaman konsep matematis siswa sekolah dasar.

Abstract

This study developed an Android-based mathematics learning media for three-dimensional geometry, focusing on distance concepts using Plomp’s (Plomp & Nieveen, 2013) educational design research framework. The development involved preliminary research and prototyping, including expert review, one-to-one evaluation (5 students), small group evaluation (10 students), and a field test with 30 twelfth-grade students in a one-case study. Data were collected through expert review, practicality questionnaires, classroom observations, interview, and pretest–posttest spatial assessments. The expert review confirmed the validity of the content, linguistic, instructional design, and instructional media communication aspects, while practicality evaluation showed that the media was easy to use and engaging. Field test results indicated positive trends in students’ spatial abilities, with improvements in spatial visualization (+32.22%), spatial relations (+15.11%), and spatial orientation (+12.78%), and a significant pretest–posttest difference (t(29) = 7.22, p < 0.001), which supported the media’s potential to scaffold spatial reasoning within the design research context. Although the normalized gain was modest (0.24), this result underscores the gradual nature of spatial development and provides formative input for design refinement. Two design principles were identified: (1) integrating interactive three-dimensional visualization to bridge iconic and abstract representations, and (2) implementing active scaffolding to connect visual intuition with precise mathematical procedures.
