This study aims to identify common misconceptions about photosynthesis and plant respiration among Form Four (Grade 10) students by developing two-tier multiple-choice test questions. This descriptive survey research was carried out using a quantitative approach, with 500 study samples. The items in Photosynthesis and Plant Respiration Diagnostic Test (PRDT) was designed in two parts; Part One tested the students’ knowledge of concepts, and Part Two tested the students’ understanding and reasoning. Rasch analysis was used to obtain the option probability curves for each item. The option probability curves present a visual image of the distribution of correct answers and misconceptions across the spectrum of student knowledge. The findings showed that students had 43 common misconceptions, which can be categorised into the inability to trace matter, energy as well as scale and location. The findings brought significant implications on the progress of the teaching and learning of Biology.
