Development And Validation Of An Instrument To Measure Science Teachers' Understanding Of Fink's Taxonomy

Abstract

Fink's Taxonomy, emerging as an alternative to Bloom's Taxonomy, presents a valuable framework due to its circular and interconnected nature, emphasizing affective aspects. However, there is a lack of clarity in measuring teachers' understanding levels of Fink's Taxonomy in the teaching and learning process. This study aims to develop items and measure the content validity of an instrument to assess science teachers' understanding levels of Fink's Taxonomy. The instrument development in this study involves two main phases: instrument construction phase and instrument content validation phase. The instrument construction phase in this study involves a literature review to conceptualize and operationalize the measurement instrument of Fink's Taxonomy. The instrument used in this study is a Likert scale questionnaire with 4 points. The content validation phase involves four steps: construction of expert review forms, selection of expert review panels, expert validation assessment, and analysis of content validity data. Content validity data analysis in this study uses Content Validity Ratio (CVR) with eight experts, resulting in a critical CVR value of 0.75. Fink's Taxonomy instrument comprises six constructs and 95 items. The analysis findings indicate that 88 out of 95 items are categorized as appropriate items with CVR values ranging from 0.75 to 1.00. Seven items showing values below the critical CVR require refinement and are retained in the instrument for pilot testing. The implication of this study lies in the ability to develop a Fink's Taxonomy instrument with high content validity. Further research on content validity can be conducted using CVI analysis, which can provide better item screening results and assess the validity of each domain and the entire instrument.
