Some examples of tasks which have been exploited in this way are presented with comments about some of the difficulties encountered.隼鹰 发表于 2025-3-28 21:42:10
Zusammenfassung und Implikationen,t which is normally expected in algebra, we can get a better understanding of the fundamental changes required of pupils in the passage from one mode of treatment to the other (conflicts, necessary adjustments, new constructions). Any didactic setting (choice of appropriate situations and interventions) necessarily relies upon this knowledge.鞭打 发表于 2025-3-28 23:13:58
