In the study, data collection tools included, a 17-item Newton's Law of Motion ConceptAchievement Test (pre assessed for validity and reliability by the researchers).Moreover a 5-item, open-ended questionnaire developed by the researchers was usedas post test. In addition, 16-item self-evaluation form (developed by Akçınar et al,2017) indicating the experimental group participants’ opinions and evaluationsregarding the process were collected to obtain supporting / supplementary data. TheNewton's Law of Motion Concept Achievement Test was designed based on the worksof Şalgam (2009) and Atasoy and Akdeniz (2007).Before the beginning of the main applications 81 10th grade students were given theNewton's Law of Motion Concept Achievement Test to approve reliability. Thereliability coefficient was calculated as 0.69 in the pilot study. The open-endedquestionnaire and the test questions were reviewed by experts in physics, educationalassessment and evaluation, as well as linguists to ensure the validity and reliability.
