Designing an ice cream making device: An attempt to combine science learning with engineering
2017 (English)Conference paper, Abstract (Refereed)
In the current study, lower secondary school students’ problem-solving was explored while using a design-based science learning (DBSL) approach. A learning module was developed within which students were expected to design an ice cream making device. The goal of the study was to introduce the DBSL module and to explore how student design products can be characterised and eventually, assessed. Data were gathered by students’ written reports and video recorded classroom observations. As a result of the study, a set of assessment criteria was developed which covered the functional, structural, safety and feasibility aspects of the device. According to the criteria, it was found that amongst the initial individual design projects (N=23), only eight could be classified as realistic, nine as realistic with reservations while seven were classified as unrealistic. The initial difficulties, though, were overcome by peer support, teacher guidance, and some trial and error experiences resulting in five mostly realistic group designs.
