Development of Motivation Scale towards Context-Based Biology (MSCBB): A Study on Reliability and Validity

Purpose: The aim of this study is to develop a valid and reliable scale determining the students’ motivations towards context-based biology. Design & Methodology: In the study, survey method has been used. For this aim, previously literature was examined by the research and the 40 item-draft scale was prepared by taking the expert opinion for these initial items. This draft scale, which was a five-point Likert type, applied to totally 209 (102 female, 107 male) students attended to a secondary school in Kocaeli. The validity and reliability analysis of the scale was done in the light of the data obtained after the treatment. Findings: In the result of the item analysis and the exploratory factor analysis, it was found that the scale had a construct of 3 factors with 34 items and the total variance explained was 50.718%. Additionally, Cronbach Alpha internal consistency was calculated for the reliability analyzes of the scale and it was found as .943 for the whole scale. Implications & Suggestions: In line with your research results, it was implied that this scale is a valid and reliable measurement tool for determining the students’ motivations towards context-based biology
