Abstract

Biophysics is an introduction-level course in the field of Biomedical Sciences were learning difficulties have been observed. Because the perception of difficulty is subjective, its quantification depends on transforming an individual’s subjective perception into an objective reality. Our study aimed at developing an instrument that could measure the perception of difficulty for the course of Biophysics. For this purpose, the course learning difficulty perception instrument (IPDAB) was designed, and it contained nine items based on a Likert scale scoring from 1 to 5. The sample consisted of 155 students from the Faculty of Medicine of the University of Panama. The instrument’s internal consistency was performed with a Cronbach’s alpha test and an exploratory factor analysis by the principal component’s method with Promax oblique rotation. Descriptive statistics indicated that, on average, students perceive module R2 (? = 3.79), where concepts of biopotentials, neurotransmitters, and synapses are studied, with greater difficulty. The Kaiser-Meyer-Olkin test showed a value of 0.682. The Cronbach’s alpha statistic was 0.719. IPDAB allows us to elucidate the issues that represent the most significant difficulties for students. The result is an instrument with acceptable psychometric properties that are valid, reliable, and easy-to-apply and interpret in samples of Panamanian university students.
