Abstract

This study aims to determine the relationship between self-efficacy and the learning difficulties experienced by Grade XI students at SMAN 1 Telaga regarding Higher Order Thinking Skills (HOTS) in the context of the "Cell" topic. Learning difficulties in this study are indicated by students' performance on HOTS tasks, which encompass the abilities to analyze (C4), evaluate (C5), and create (C6). The study employs a quantitative approach using a correlational method. The population consisted of 312 Grade XI students across 10 classes, with a sample of 34 students selected via cluster random sampling. Research instruments included a self-efficacy questionnaire and a HOTS test on the "Cell" topic. Data were analyzed using descriptive statistics and the Spearman Rank correlation test. The results indicate that student self-efficacy falls into the moderate category (67% average), while HOTS proficiency averaged 58%, indicating a moderate level of learning difficulty. The Spearman Rank test yielded a correlation coefficient of 0.387 with a significance value of 0.024 (p < 0.05). These results demonstrate a significant relationship between self-efficacy and learning difficulties regarding HOTS in the "Cell" topic. The findings suggest that students with higher self-efficacy tend to possess better HOTS capabilities, thereby experiencing fewer learning difficulties. However, the low strength of the relationship indicates that learning difficulties regarding HOTS are also influenced by factors other than self-efficacy.

Abstract

This study aims to describe the learning outcomes of grade XI.9 students at SMA Negeri 2 Gorontalo after participating in an integrated e-module on the digestive system, covering malnutrition and local food, based on Project Based Learning (PjBL). The study employed a quantitative approach with a descriptive method and a one-shot case study design. Thirty-five students were selected using purposive sampling. Data were collected through a posttest and observations of learning implementation, then analyzed using descriptive statistics. The results showed that student learning outcomes were in the high category, with an average posttest score of 79.29. Most students achieved learning outcomes in the high and very high categories. The implementation of the learning was in the very good category, as indicated by the high level of teacher and student activity during the learning process. Students were also able to complete projects and produce local food-based products related to the digestive system and malnutrition.

Abstract

The digestive system is a biology material that has abstract characteristics, so it often causes learning difficulties in students. One effort that can be done to improve student learning outcomes is through the use of audio-visual learning media associated with local food education. This study aims to determine the differences in learning outcomes of grade XI students after the application of audio-visual media based on local food education on the digestive system material. The study used a quantitative approach with a quasi-experimental method and a post-test only control design. The study was conducted at SMA Negeri 1 Suwawa with a sample of two classes consisting of an experimental class and a control class. Learning outcome data were collected through tests that had been tested for validity and reliability. Data were analyzed using normality, homogeneity, and independent samples t-test. The results showed that there was a significant difference between the learning outcomes of students who used audio-visual media based on local food education and students who used audio-visual media without local food education. The average score of the experimental class was 77.10, higher than the control class at 56.62. The results of the independent samples t-test showed a significance value of 0.000 < 0.05, thus rejecting H₀ and accepting H₁. These findings indicate that audio-visual media based on local food education is more effective than audio-visual media without local food education in improving student learning outcomes on the digestive system.

Abstract

This study aims to develop and validate digital comic learning media based on research findings regarding microplastics, serving as a learning resource on plastic pollution in aquatic environments. The resulting product presents microplastic-related content through a contextual and engaging illustrated story, with the expectation of enhancing students' understanding of the issue of microplastic pollution. The study employs the Research and Development (R&D) method using the Plomp model, which comprises three stages: 1) preliminary research; 2) prototyping; and 3) assessment. Validation was conducted by subject matter and media experts, yielding validity scores of 91.66% and 91%, respectively. Based on these validation results, digital comic possesses a validity level of 91.33% and is categorized as highly valid, making it suitable for use as a learning resource regarding microplastic pollution.
