Study of Moroccan Pupils’ Skills in Solving Chemistry Problems at First Year of High-School

Summary/Abstract: This study purpose to analyze the macro-skills (assimilate, analyze, and achieve) that Moroccan pupils (16 – 17 years) of high-school (first-year classes) master to solve chemistry problems involving chemical concepts such as equation of reaction, complete reaction, molar mass, amount, volume, concentration, RICE table, and dilution. The pupils were asked to provide answers on problems’ questions including implicit tasks, which are arranged from the simple to the complexe at the problems’ end. The pupils’ answers are analyzed in terms of macro-skills with regard to the (1st, 2nd, 3rd degree) skills, which pupils would master to succeed the different tasks relevant for the problems, and discussed in terms of novice/expert problems solvers taking considering conceptual understanding and algorithms that pupils could master to solve correctly the problems’ tasks. The findings show that pupils succeed tasks, which require mastering of assimilate skills (1st degree skills) more easily than those requiring others skills, especially achieve skills (3rd degree skills), needed to solve the complexe tasks.
