Abstract This research investigated the effect of problem-based learning (PBL) for the topic of energy metabolism in a biochemistry course on the academic achievements of students studying in the healthcare field in a nursing department. The study had a one-group pre-test and post-test research design. The study group consisted of firstyear students studying at the Department of Nursing in the Faculty of Health Sciences at Bulent Ecevit University (N = 210). The scenario, entitled BEmre’s Sports Life: Is It True or False? You Decide!^ and consisting of five educational sessions was developed and implemented after taking into account the opinions of two biochemistry and pedagogical experts. The BEnergy Metabolism Achievement Test^ (EMAT) and a structured interview form were used as data collection tools. The content analysis of the EMAT post-test indicated that PBL increased students’ responses in the sound and partial understanding categories and the Wilcoxon signed rank test result revealed that there was a significant difference between EMAT pre- and post-test scores in favor of post-test scores (z = − 12.567, p < .05). In addition, content analysis of the structured interview indicated that the majority of students expressed positive opinions about the PBL approach, including that it was memorable, interesting, and related to daily life.

Introduction Biochemistry is one of the branches of science and is also a common branch of chemistry, biology, medicine, and nursing fields. In other words, biochemistry is an interdisciplinary field and it includes the application of chemistry to biological processes at cellular and molecular levels (Kulak and Newton 2014; Narad et al. 2016; Ouyang et al. 2007). Metabolism, a broad topic in biochemistry courses in the field of healthcare, includes the metabolic pathways involving a number of biochemical reactions catalyzed by enzymes (Dixon and Webb 1979; Karp and Mavrovouniotis 1994; Lehninger 1982). The most important metabolic pathways include glycolysis, gluconeogenesis, lipolysis, the tricarboxylic acid cycle (Krebs cycle = citric acid cycle = TCA), and amino acid metabolism. These metabolic pathways are particularly important in providing a balance between nutrition and energy consumption. They are among the complex issues that students particularly struggle to learn, since a product that is a result of a biochemical reactio
