Dear Ms. Indah Sari, Thank you for your question.
I want to try to answer your question:
1. The contextual problems given are phenomena about the reaction rate found in
the surrounding environment or daily life. For example, on the topic of factors
affecting the rate of reaction, students are given a contextual problem about
surface area factors, for example, the use of antacids which is recommended to
chew before swallowing because it will be more effective in reducing stomach acid,
and then students will be guided to formulate questions and hypotheses about the
problem related to the reaction rate.
2. Yes, each group was given the same contextual problem. The difference is
students in the control group are not guided to formulate hypotheses from the
questions they make.
3. The instrument used was essay questions that contained 3 indicators of
analytical thinking ability, namely differentiating, attributing, organizing. For
example, in question with differentiating indicators, there are experimental data
and experimental results graphs, students are expected to be able to organize the
experimental data provided to determine the right graph.
Thank you
