Abstract

This research aims to create a tool for assessing students' computational thinking (CT) skills in relation to biology concepts. The study followed a research and development approach, utilizing a modified 4D design model, with the dissemination phase excluded. Various data collection techniques were employed, including observations, literature reviews, documentation, surveys, interviews, and tests. The findings showed that the developed instrument was valid, having been evaluated by three experts. The material expert rated it at 95%, the assessment and evaluation expert at 88%, and the linguist at 90%. In terms of readability, the instrument scored 75%, indicating a "good" rating. The overall validity of the instrument was found to be 0.70, placing it in the high validity range, while its reliability score was 0.82, reflecting a very high level of dependability. The assessment of students' computational thinking skills in biology revealed that 25% of students scored in the low range, 28% in the medium range, and 57% in the high range. From these findings, it can be concluded that the CT test tool is both valid and appropriate for evaluating students' computational thinking skills.

Abstract

Student engagement in biology learning remains a significant challenge, particularly when students are required to understand abstract concepts such as plant anatomy, cell biology, and the nervous system. Virtual Reality (VR) offers immersive and interactive learning environment that has potential to enhance students’ learning experiences and engagement. This study aimed to develop and evaluate MilleaLab-based Virtual Reality learning media for teaching plant anatomy, cell biology, and the nervous system. The study employed the ADDIE development model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The feasibility of the developed media was assessed by subject matter expert and VR media expert using validation sheets, while student engagement was measured through a student engagement questionnaire. The result indicated that the VR-based learning media achieved feasibility scores above 80%, demonstrating that the media is highly feasible for biology learning. Furthermore, the findings revealed that the VR media contributed positively to students’ behavioral and psychological engagement, with average score above 3.0, while cognitive engagement showed a lower average score below 3.0. These findings suggests that MilleaLab-based VR media can serve as innovative learning alternative for teaching complex biology concepts by promoting active participation and positive learning experiences among students.
