Abstract
The research is a pretest-posttest experimental design that integrated peer instruction into the dialogical argumentative instruction to investigate the authentic learning experience among College students. The participants were pre-service physics students of a College of Education in Nigeria. The mixed-method approach was adopted to obtain data for the study. The research instruments were Electromagnetism Physics Test (EPT) and Semi-structured interviews. The ANOVA and thematic coding were used to analyse the data obtained. The outcome of the research shows that students' authentic learning was enhanced with the integration of PI into the dialogical argumentation instruction. It also shows that the gender difference in academic performance was not significant. The study makes some recommendations; one of them is further studies on PIDAM because this is the first study on PIDAM in a College.
