The jump from junior high to grade 10 in Phase E
Grade 10 is Phase E of Indonesia's Kurikulum Merdeka. Students still take the full set of general subjects, yet the material becomes far more abstract. Quadratic functions in maths, the basic laws of chemistry in chemistry, expository writing in Indonesian: each asks students to understand why a rule holds, and memorised formulas stall as soon as a question is phrased a little differently.
More teachers set work, too. Assignments arrive from several directions in the same week, and clubs or student organisations begin to ask for real commitment. Many students carry over their junior high routine of rereading notes the night before a test and highlighting the textbook. It feels productive, yet the 2013 review by Dunlosky and colleagues of ten learning techniques rated both rereading and highlighting as low utility.
There is a practical reason to adjust early. Report card marks from the first semester of grade 10 already feed the average used for SNBP, the admission route based on school records, together with semesters 2 to 5. Grade 10 is also when guidance on elective subjects begins, so the first semester doubles as a time to notice which fields feel interesting. Students who spend their opening weeks trying out a new way of studying tend to start the second semester at a calmer pace.
Report cards count from the first semester of grade 10, so the cheapest time to build new study habits is the first few weeks.
