Designing Physics Experiment and Assessment of Inquiry-Based Laboratory to Exercise Higher Order Thinking Skills

This work aims to design the inquiry-based laboratory as well as the cookbook laboratory model to train student’s high order thinking. The investigation train how scientists invented standard quantities of length, time, and mass through the inquiry activity approach. The model is a part of the experiment assessment models under the revised 2013 Indonesian curriculum. The model was successfully applied to K-10 in a Senior High School. The result shows that the best attainment of the model is very high with (0.90) item validity as much as its reliability, good (0.50) discrimination power, and medium (0.62) difficulty index. Average students achieve 74% of the experiment process test including investigating problems, tools, method, procedure, data, analysis, and conclusion. We have found that students can elaborate their facts and theory to synthesize, generalize, explain, hypothesize, or reach some conclusion or interpretation through applying inquiry-based laboratory and training their high order thinking skills.
