Abstract

This represents an advanced Research and Development (R&D) study designed to evaluate the practicality and effectiveness of an e-encyclopedia which has been built and validated with very valid results. The fourteen students who formed up the research subjects. Pre-test and post-test questionnaires, observation sheets, and student response questionnaires were used as the study instruments. The study data analysis technique was descriptive quantitative through three stages, namely calculating the percentage value of practicality and effectiveness tests, Mann-Whitney U non-parametric test, and N-Gain (g) test. An average percentage value of 85.63% was attained with a very practical category in the practicality test analysis findings. With a percentage score of 81.13%, the effectiveness test analysis revealed a very strong response from the students. In contrast, there was a significant difference between the pre-test and post-test findings in terms of raising CTS by 0.78 with a high category, according to the effectiveness test analysis results using the Mann-Whitney U test and the N-Gain (g) test. The conclusion shows that Canvaflipedia to improve CTS is proven to be practical and effective, so it is suitable for use.

Abstract

Background: The need for e-encyclopedia development due to the low utilization of ICT in developing e-encyclopedias makes students lazy and less interested in studying the morphological diversity of Pteridophyta based on local potential. Therefore, the development of Canvaflipedia addresses the above problems as a learning medium that is more interactive and easily accessible to students, and can be applied in the PBL model of learning. This study aims to design and test the validity of an electronic encyclopedia related to the morphological diversity of Pteridophyta based on local potential in PBL learning. Methods: The type of research used is an R&D study with a 4D (Define, Design, Develop, and Disseminate) model, but the research only reached the development stage, which focused on validity testing by three validators using a validation sheet as a research instrument. Data was collected by compiling the results of the validation sheet and analyzed descriptively and quantitatively to interpret the validity results obtained. Results: The findings of the material expert validation test analysis showed a very valid category with an average value of 91.11%. By contrast, the results of the media expert validation test analysis showed a very valid category with an average value of 87.70%. Conclusions: Based on these results, the Canvaflipedia developed is very valid for application in PBL learning.

Abstract

Research that discusses and examines the role of Telegram in developing science process skills (SPS) in low plant botany (LPB) learning in depth is still minimal. Therefore, the research aims to determine the level of SPS of students in LPB online learning through Telegram. The research method used a quantitative descriptive study of students' SPS levels after LPB learning through Telegram. The research was conducted with 60 students, using a questionnaire as the research instrument, followed by quantitative analysis. Results showed that students had a deep understanding and an adequate level of SPS in LPB online learning through Telegram, as evidenced by the average SPS score of 72.91% in the high category. Thus, Telegram has been proven to help develop students' SPS in LPB online learning. The study provides implications for educators by utilizing Telegram as a platform for online learning methods to develop students' SPS skills.

Abstract

The urgent need for a structured instructional framework that elevates creative problem-solving efficacy necessitates the integration of a pedagogical deep learning approach focused on emotional and cognitive engagement, with the group investigation model. The research aims to examine the effects, effectiveness, and student perceptions regarding the implementation of a group investigation learning model based on a deep learning approach on students' creative problem-solving skills in natural science. Utilizing a quasi-experimental research design with a nonequivalent control group, this research evaluated a sample of 60 students (N = 30 per class). Data collection utilized pretests, posttests, rubrics, and response questionnaires, which were subsequently analyzed using descriptive percentages, hypothesis testing, N-Gain scores, and effect size values. The results showed a notable difference in creative problem-solving skills between the experimental and control groups (p = 0.001 < 0.05), with a high N-Gain score (0.71) and a very high effect size (1.85). Additionally, student responses were in the highly positive category (83.40%). It can be concluded that integrating deep learning into the group investigation model effectively improves creative problem-solving skills in natural science. The study implies that this innovative learning framework can be adopted as an alternative strategy to foster creative problem-solving skills.
