Application of CBL Combined with Blended Learning Method Based on Ebbinghaus Forgetting Curve Theory in Hematology Internship Teaching for Eight-Year Undergraduate Students
Objectives This study aims to explore the application effect of the hybrid teaching method based on the Ebbinghaus forgetting curve law combined with case-based learning(CBL)in the internship teaching of hematology for eight-year clinical undergraduate students in the context of the organ system integration course.Methods A total of 38 eight-year clinical undergraduate students who entered the hematology department of a hospital of Peking University from March 1 to October 31,2023 were selected and randomly divided into an experimental group and a control group,with 19 people in each group.All students learned the same content.The experimental group used a hybrid teaching method that combines the Ebbinghaus forgetting curve law and CBL,while the control group used traditional teaching methods.After class,students in the experimental group were subjected to review sessions and question answering by the teacher via an online application at specific time points,in accordance with the Ebbinghaus forgetting curve theory.In contrast,students in the control group conducted their reviews independently,with teachers available to answer questions throughout the internship period.Following the internship,both groups of students underwent a unified rotation examination to compare their theoretical test scores.Additionally,a questionnaire was administered via an online platform to gather feedback on the current teaching model from both student groups.Results The median score on the theoretical examination for the experimental group was 100.00(94.50,100.00),while that of the control group was 94.50(89.50,97.50).Independent sample non-parametric testing revealed that the results of the experimental group were significantly higher than those of the control group,with a statistically significant difference(P＜0.05).In terms of teaching feedback,students in the experimental group rated the teaching model significantly higher than those in the control group in subjective quantitative scores for stimulating learning interest,improving learning initiative,cultivating pioneering thinking and innovative abilities,enhancing mastery of basic theories,and refining clinical thinking ability(P＜0.05).Conclusions The application of CBL combined with blended learning method based on Ebbinghaus forgetting curve theory shows promising feasibility in the clinical internship training of medical students.This approach contributes to enhancing the proficiency in both basic and clinical theoretical knowledge of hematology among eight-year undergraduate students in a clinical setting,ultimately leading to improved teaching outcomes.
