Background: As part of a study to investigate the influence of the mode of presentation of a laboratory instruction, the cognitive load, and the self-efficacy for experimenting on learning performance a workshop was developed about visible and infrared optics.
Purpose: The workshop named “(Invisible) Light – Discovered with the Smartphone” was structured according to the basis-model “Concept Building” from Oser. The lesson planning for the workshop will be shown in the article and its suitability will be theoretically justified.
Design and Method: The theoretical contribution is devoted to the following question: How could a 90-minutes lesson be structured so that students can successfully integrate a new concept into their existing knowledge structure? Empirically founded theories for structuring lessons on the sight structure (processing of teaching) and basis-model (processing of learning) are explained, with a special focus on the basis-models of teaching. The explanation about the chain of necessary steps in the basis-model “concept building” takes place through the description of the planned teaching phases of the workshop.
Results: The presented workshop was piloted with seven classes from junior high school and, after minor changes, carried out forty-nine times in this form. The learning effect of the workshop could be proven by means of quantitative statistical evaluations. However, the learners failed in transferring the newly acquired knowledge to other contexts.
Implications for classroom practice and future research: The explanations on the lesson planning of the workshop can be viewed as an example of a possible structuring of lessons when acquiring new concepts in physics lessons. The workshop is suitable as a framework for the above-mentioned study, whereby the focus can be placed on the mode of presentation of laboratory instruction.
