Abstract

Coastal ecosystem degradation in Pagimana District, combined with science instruction that remains largely theoretical, underscores to the need for a learning model that can foster students’ environmental awareness more comprehensively. This study examined the effectiveness of the PjBL-STEAM-IC model in improving students’ environmental awareness in coastal schools across the four KABS dimensions: knowledge, attitude, behavior, and skills. The study was part of a Research and Development project and specifically reports the field-testing phase, which included limited trials, wider trials, and operational implementation. Participants were 150 seventh-grade students from four coastal junior high schools in Pagimana District. Data were collected using an environmental awareness questionnaire and analyzed using descriptive statistics, N-gain, the Wilcoxon Signed-Rank Test, and the Kruskal-Wallis Test. The results showed that the PjBL-STEAM-IC model effectively improved students’ environmental awareness across all four dimensions. The mean score increased from 67.41 before implementation to 86.81 after implementation, with N-gain values ranging from 0.62 to 0.64, and all dimensions showed significant differences (p < 0.001). These findings suggest that the PjBL-STEAM-IC model is a promising contextual science learning alternative for strengthening environmental awareness in coastal schools.

Abstract

Coastal science learning in Pagimana, Central Sulawesi, has not adequately connected local environmental problems with students’ thinking development and environmental awareness. This study aimed to develop and examine the expert validity of the PjBL-STEAM-IC model, in which IC denotes Innovation and Creativity, for SOLO-based thinking skills and environmental awareness in coastal schools. Using an adapted Borg and Gall research and development procedure, this article reports the needs analysis, hypothetical model design, development of instructional materials and research instruments, expert validation, and Product Revision I. Three validators evaluated the model and its supporting products; their ratings were analysed using Aiken’s V, and their written recommendations were examined descriptively. The developed model comprises six phases linking coastal environmental problems, STEAM-IC project activities, SOLO-based reasoning, and four dimensions of environmental awareness: knowledge, attitude, behaviour, and skills. All validated components were classified as very valid, with Aiken’s V coefficients ranging from 0.902 to 0.961. Expert feedback led to clearer operational syntax, stronger theoretical mapping, more explicit STEAM-IC integration, improved alignment with SOLO-based thinking and environmental awareness, and refinement of the student response questionnaire. The model and its supporting products were therefore considered sufficiently valid to proceed to subsequent classroom field testing.
