In this paper, we describe the structure, development, and validation process of customized pedagogical kits (CPKs) for differentiated instruction (DI) in chemistry. The CPKs rely on the DI approach, comprising varied pedagogical activities (e.g., games, inquiry activities, puzzles, simulations, models) designed as treatments, to help chemistry teachers personalize their teaching according to students’ misconceptions. The kits are based on the response to intervention (RTI) model, where the teacher applies an ongoing evaluation to meet the individual student’s needs within an evolutionary flexible process of learning. Each kit includes a diagnostic task, its characterization, pedagogical treatments for diagnosed misconceptions, and an assessment task, to evaluate the effectiveness of the treatments implemented in the classroom. The kits are developed along relevant literature criteria for using DI strategies and are based on constant validation and ongoing assessment, as demonstrated in the Redox-reaction CPK development. The validation and impact of the CPK on students’ achievements are supported by 25 chemistry teachers that implemented the full kit in their classrooms. Furthermore, the CPKs developed in the present research have succeeded in resolving many of the difficulties and challenges mentioned in the literature as obstructing the implementation of DI. |
