Developing digital learning resources for the topic “Substances and their changes” based on the flipped classroom model in grade 7 Natural Science teaching

Abstract

The study confirmed that digital learning materials are a crucial component in implementing the flipped classroom model for the topic "Matter and its Transformation" in 7th grade Natural Science curriculum. This approach contributes to increased learning interest, seft-learning ability,and the effectiveness of teaching activities organized by teacher. The study employs methods of document analysis and synthesis, surveying the current situation, designing digital learning materials, conducting pedagogical experiments, and processing data using mathematical statistics. The digital learning materials system includes video lectures, digital worksheets, interactive exercises, virtual experiments, and mind maps, organized under the pre-, while-, post-stages in the flipped classroom model. The pedagogical experiment was conducted on two groups of 7th grade students: an experimental group and a control group. The results showed that the average scores of the experimental group were 7.30 and 7.12, higher than the control group's scores of 6.40 and 6.47, respectively; the standard deviation ranged from 1.32 to 1.41. The proportion of students achieving a "good" or "excellent" grade in the experimental group was significantly higher than in the control group. Statistical testing showed that the difference between the two groups was statistically significant with p = 0.00430 and p = 0.02103 (p < 0.05). These results confirm that digital learning materials built under the flipped classroom model are feasible and effective in improving learning outcomes, developing self-learning abilities, and enhancing student initiative in teaching the topic "Substances and their changes" at the lower secondary level.
