Abstract
This study aimed to investigate the effect of problem based learning (PBL) blended e learning on the higher order thinking skills (HOTS) of seventh grade students in environmental pollution and their environmental care attitudes. The study was conducted using a quasi experimental design. The participants of the study were 68 students, divided into two groups, one an experimental group (34 students) and the other a control group (34 students). HOTS test (15 multiple choices) and questionnaire (hands on activity) were designed to confirm the study validity and reliability. SPSS was used to analyse the data. The finding revealed that there were statistically significant differences between the experimental and the control group. The results of post test data processing (One Way ANOVA with alpha 0.05) show that Fcount more than Ftable then H0 is rejected and Ha is accepted. This shows that there is a significant effect of PBL blended e learning on the higher order thinking skills of seventh grade students in environmental pollution and their environmental care attitudes. The study is recommended to use in Indonesia education system after covid 19 pandemic end to increase education quality. This study showed increasing students environmental care awareness attitudes.
