Purpose of the study: This study aims to analyze the validity and readability of a deep learning–based electronic module (e-module) designed to improve students’ critical thinking skills on global warming material. Methodology: The research employed a Research and Development (R&D) approach using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The developed e-module integrates deep learning principles—mindful, meaningful, and joyful learning—into a Google Sites platform and is enriched with multimedia elements, including videos, animations, interactive worksheets, Padlet, and a carbon footprint calculator. The validity of the e-module was evaluated by six experts, including media experts, subject matter experts, and linguists, using Aiken’s V formula. Main Findings: The results showed that all validation aspects achieved Aiken’s V values ranging from 0.83 to 1.00, exceeding the minimum validity threshold (V > 0.78), indicating that the e-module is highly valid. Readability testing involved ten junior high school students and two science teachers and was analyzed using percentage-based criteria. The readability scores ranged from 88% to 100%, categorized as excellent across content, format, presentation, and language aspects. These findings indicate that the deep learning–based e-module is not only valid but also highly readable and user-friendly. Novelty/Originality of this study: The developed e-module has strong potential to be implemented as an innovative digital teaching material to support science learning and foster students’ critical thinking skills, particularly in addressing contextual and global environmental issues such as global warming.

Abstract

In the era of 21st-century education, mastery of Technological Pedagogical Content Knowledge (TPACK) is not enough without having higher-order thinking skills (HOTS). This study aimed to analyze HOTS-based TPACK ability in the field of Elementary School Teacher Education (ESTE). This study employed a quantitative descriptive approach with a survey design and data collection through self-assessment instruments. 1644 ESTE students of Teacher Professional Education (TPE) who filled out the instrument from various regions in Indonesia. The students consisted of 94 prospective teachers (Pre-service teachers of TPE) and 1550 TPE students who had become teachers (In-service teachers of TPE). The results showed that ESTE students of TPE showed very good mastery of HOTS-based TPACK. In the Content Knowledge aspect, 90% of students were categorized as having a high level of competence, indicating strong mastery. The ability to solve problems (53.7%) and evaluate student understanding (55.3%) were categorized as medium. In the Pedagogical Knowledge domain, the ability to manage classrooms (69.2%) and select appropriate learning strategies (66.5%) fell into the high category. For Technological Knowledge, 76.2% of students demonstrated a high ability to utilize technology effectively, although 16.9% still had difficulties in evaluating software, which was classified as low. Meanwhile, in the integrative TPACK aspect, 62.8% of students were in the high category in assessing student learning outcomes using a HOTS-based approach. In conclusion, ESTE students of TPE showed very good mastery of HOTS-based TPACK competencies, with high abilities in content knowledge, pedagogy, and technology even though challenges in evaluating software remain to exist. This study implies the need to strengthen training in technology evaluation and the application of higher-order thinking skills to ensure comprehensive and sustainable TPACK competence in teacher education programs.
