Chemical bonding is central to explaining many phenomena. Research in chemical education and the Framework for K-12 Science Education (the "Framework") argue for new approaches to learning chemical bonding grounded in (1) using ideas of the balance of electric forces and energy minimization to explain bond formation, (2) using learning…

As a representative catabolic reaction that widely exists in nature, anaerobic digestion (AD) exhibits great value regarding the global carbon cycle, renewable energy development, and environmental protection. Such an important biochemical reaction was ignored before and should be introduced into the teaching and textbooks of undergraduate…

This study was aimed at eliminating the difficulties in teaching the concepts and the students' conceptual understanding in the "Force and Energy" unit through semantic mapping. The study was conducted using the action research method. This study was conducted in the control group using the existing learning method in the science…

The aims of the study were analyzing students' understanding and skills to make concept mapping in work energy matter through C-Map application software. True experimental method with randomized control group pre-test and post-test design was utilized in the research method. The research involved 72 public high school students from second…
