Virtual Laboratory Based Online Learning: Improving Environmental Literacy in High School Students

Oftentimes the increase in industrial development is the cause of environmental problems. Environmental problems can be overcome by the presence of humans who care about the environment or have environmental literacy skills. Environmental literacy skills can be instilled from an early age, for example through practicum learning in schools. However, considering that the Covid-19 pandemic is one of the obstacles in carrying out the practice, virtual laboratory-based online learning is carried out. This study was aimed to improve students' environmental literacy through virtual laboratory-based online learning that has been developed. This research is quasi experiment with pre-test and post-test research design Control Group Design. The total sample of the study was 70 students of class X of state senior high school. The research instrument used was in the form of test questions about environmental changes material and environmental literacy questionnaires. The results showed that the N-gain value of environmental literacy in the experimental class was 29% high, 60% moderate, 11.42% low with the percentage of attitudes 66.62% and 63.43% behavior. Meanwhile, for the control class, the N-gain value was 9% high, 48.57% moderate, 42.85% low and 68% attitude and 67% behavior. This shows that virtual laboratory-based online learning contributes to increasing environmental literacy skills.

E-Learning in New Normal COVID-19 Era: Measure HOTS and Pro-Environmental Behavior about Environmental Pollution

Current environmental learning amid the COVID-19 new normal situation requires an innovation. This is due to students needing various skills to solve environmental pollution issues using Higher Order Thinking Skills (HOTS) and is implemented in the form of Pro-Environmental Behavior (PEB). The innovation is aimed at supporting e-learning utilization. This study aims to delineate university students' HOTS and PEB and examine the e-learning utilization. Method used in the study is descriptive method using survey technique. Samples involved in the research are 265 university students. The study results indicate that the students' HOTS score is, overall, in a very low category (31.37). The students' PEB score, however, is already in a very high position (89.88) as a form to prevent COVID-19 in their surrounding environment. The result of e-learning description suggests that there are still some obstacles in terms of e-learning implementation. The research concludes that the HOTS score is relatively low, whereas the PEB score must be maintained. Suggestions proposed from this study is that to develop teaching materials or learning media, in this context book or supplementary book can be develop, related to environmental pollution as a disaster mitigation effort amid the COVID-19 new normal situation.
