Digital Teaching Materials Development Containing Environmental Education Using Task Based Language Learning (TBLL)

The Covid-19 pandemic results in unavoidable changes in all aspects of life, including education. This pandemic has led to the opportunity to enter digital learning. This study aims to develop digital learning materials based on Task-Based Language Teaching (TBLT) which contains environmental education for senior high school students. This Research & Development (R&D) was based on Plomp’s development model. Digital learning materials were developed using the i-Spring application and integrated with the LMS Edmodo. The instruments used were questionnaires, observation sheets, and tests. The results of the study showed that digital learning materials were valid, practical, and effective for use in language learning. Besides, the developed model was validated with a self-validation value of 93.12% and an expert validation value of 93.18%. The developed model was tested for its practicality with a teacher practicality value of 93.54% and student validity of 80.62% with the category of very practical. The learning activity score reached 93.33% with the category of very active learning. Based on statistical data analysis, the developed digital learning materials were effective in improving learning outcomes.
