Abstract

Higher-order thinking skills (HOTS) are crucial in science education, yet students often struggle to master them, particularly in complex topics such as vibrations and waves. This study aimed to evaluate the HOTS performance of 165 eighth-grade students from five schools in Purbolinggo Sub-district, East Lampung, using a two-tier multiple-choice test analyzed through the Rasch Measurement Model. The test consisted of 12 items, each with a content question and a reasoning tier, adapted from Treagust (1988) and validated through expert judgment. Rasch analysis indicated that most students demonstrated low HOTS ability, especially in the creating domain (C6), involving generating novel ideas or solutions. In contrast, analyzing (C4) and evaluating (C5) were relatively easier but still reflected limited mastery. The highest difficulty appeared in questions requiring divergent thinking and complex synthesis. Item fit statistics showed good instrument validity (person reliability = 0.93; item reliability = 0.83). These findings highlight the importance of implementing learning strategies that foster creativity and synthesis, such as problem-based learning or project-based approaches. The study was limited to one geographic area, which may restrict generalizability. Future research should explore broader contexts and incorporate qualitative data to deepen understanding of HOTS development in science.

Abstract

This study aimed to identify mycorrhizal fungi, primarily from the genera Rhizoctonia and Tulasnella, on orchid roots and develop leaflet-based teaching materials using the Research and Development (R&D) model with the 4D approach (Define, Design, Develop, Disseminate). Fungal identification was conducted through microscopic examination and molecular techniques (ITS rDNA sequencing) to ensure accurate classification. The 4D model involved defining student needs, designing leaflet content focused on fungal symbiosis, developing draft materials, and disseminating the final leaflet for classroom use. The effectiveness of the leaflet was evaluated with 40 students through pre- and post-tests measuring knowledge of fungal roles in orchid growth. Results showed the average pre-test score increased from 48.5 to 85.2 in the post-test, with an N-Gain score of 0.722 (72.29%), indicating moderate effectiveness. Improvements were most notable in students’ understanding of fungal identification and symbiotic functions. These findings demonstrate that leaflet-based teaching materials developed from precise fungal identification can significantly enhance student comprehension of Kingdom Fungi concepts.

Abstract

This research explores the implementation and management of the teaching factory (TEFA) models at Vocational High School (SMK) St. Mikael, Surakarta, Indonesia. The research focuses on the management of production units owned by the school and how the school collaborated in industrial cooperation with relevant enterprises. A qualitative approach with a case study method was employed, collecting data through documentation, interviews, and observation. The findings reveal that the teaching factory is implemented through block schedules and job sheets to enhance student skills, with professional management of the production unit. Additionally, the industrial cooperation bridged by the school and its business partners has involved apprenticeships, product marketing, worker deployment, and industrial work visits. Among these four programs, apprenticeships are believed to be the most effective in enhancing students' vocational competencies. Implementing the TEFA model has assisted the school in equipping its students with competencies aligned with the industrial demands for qualified and competent workers. The study suggests that other vocational schools implementing TEFA might consider managing their production unit by employing block schedules and job sheets in the production unit, and building industrial partnerships to address the demand of the current industry trends.
