Development and Validation of a Four-Tier Test for the Assessment of Secondary School Students' Conceptual Understanding of Amino Acids, Proteins, and Enzymes.

ABSTRACT: Previous studies noted the scantiness of diagnostic instruments for the assessment of students' understanding of fundamental biochemistry concepts. Consequently, within this study, a four-tier test for the examination of secondary school students' conceptual understanding of amino acids, proteins, and enzymes has been developed. Items in the test consist of the answer tier, the reason tier, and a confidence rating for each of these tiers. Following the three-phase development process, the final version of the test, comprising eight items, was administered to 123 students in the main study. The internal consistency of both cognitive scores and confidence ratings proved to be adequate (Cronbach's alpha values were 0.76 and 0.87, respectively) and the test-retest reliability was also satisfac
