PROBLEM TO BE SOLVED: To accurately judge lacking points in a learning process of an individual pupil and to accurately extract an optimum teaching material for learning the lacking points. SOLUTION: When a return code of a small unit 'written problem (2) for simultaneous equations' is (1), small units directly under the unit concerned are two units 'written problem (2) for equation' and 'complicated simultaneous equations' and respective return codes are (1.1) and (1.2). Small units directly under the small unit 'written problem (2) for equation' are four small units 'expression (4) based on literal expression', 'equation (3)', 'equation (4)', and 'written problem (1) of equatmon' and their return codes are (1.1.1), (1.1.2), (1.1.3), and (1.1.4). Namely the return code of an optional small unit includes all the return codes of small units arranged on its high school year side. |
