Improving middle school students’ aspects of practice related to designing solutions through lessons about forces based on "three-dimensional learning" approach
Abstract
This study investigates the impact of a sequence of lessons about forces on middle school students’ aspects of practice related to designing solutions. Instructional materials about forces based on the "three-dimensional learning" approach were developed and applied to 20 students of the 2nd grade of Gymnasium. Data collection was carried out through questionnaires and students’ worksheets. From the analysis of the data, it emerged that, through this sequence of lessons, it is possible to improve the following aspects of practice related to designing solutions: defining a problem to be solved, specifying criteria and constraints that the final product must meet, designing and making a model/prototype to meet a criteria or constraint, and deciding to accept or reject a model/prototype.
