In recent years, studies by education researchers indicate that, despite various instructional methods to enhance the conceptual understanding of seasons, the reasons for the formation of seasons and the processes involved are still not fully grasped. This research aims to investigate the fundamental reasons for the difficulties in comprehending the formation of seasons and to develop possible solutions. To achieve this goal, a physical model based on the “Change in the Amount of Energy Falling onto a Unit Surface (CAEFUS)” of parallel beams of sunlight as Earth orbits around the Sun with a tilted axis of approximately 23.5 degrees was developed and applied to participants, and data were collected. These instructional processes were applied to experimental and control groups. The research was conducted on 148 eighth-grade students in a state school in Samsun (the city in Turkey) province. Exploratory factor analysis was used to analyze students' drawings and separate them into their most prominent elements. The quantitative data analysis, consisting of multiple-choice questions, utilized the SPSS 22.0 statistical program. According to ANOVA Results for SEMAT Achievement Scores, a significant difference was determined between the experimental and control groups (F = 7.625, p < 0.05). In addition, the control group mean in the pre-test fell below the experimental group mean in the pre-test. However, the mean of the experimental group in the post-test exceeded that of the control group (Pre-test‘e’ = 1.54, Pre-test‘c’ = 1.82; Post-test‘e’ = 3.21, Post-test‘c’ = 2.86). The data analysis revealed that the CAEFUS-based model significantly impacted the meaningful teaching of the nature of seasons. These results were thoroughly evaluated through a detailed comparison with the literature.

Teacher education is a critical component of the educational system, as it provides the skills and knowledge necessary for effective instruction in science and other related subjects. The purpose of this research is to enhance the incomplete and incorrect knowledge and skills of science teachers related to the formation of seasons by using a physical model that reveals the “change in the amount of energy per unit surface (CAEUS)”. Twenty-nine teachers from different regions of the country conducted experimental studies with physical models related to the formation of seasons, as part of a 5-day training program that included topics on astronomy. In this study, in which descriptive statistics, inferential statistics, and thematic analysis were used, it was observed that the comprehension of the causes and effects of the change in the amount of energy per unit surface was very successful in the development of mental models for understanding the seasons. Furthermore, the teachers reported that they were able to use the knowledge and skills they gained from the program in their teaching practice. The results obtained were compared with the literature and interpreted accordingly.
