The influence of discussion groups in a case-based learning environment. Furthermore, in an educational setting, quantitative differences in test scores might produce meaningful qualitative differences in course grades even in the absence of a p value that is statistically significant. Within three semesters students get familiar with the fundamental MBA program 10 courses. This indicates that case studies are more effective than more commonly used, traditional methods of content delivery at promoting learning of a variety of core concepts covered in general biology courses.

Positive point differences indicate how much higher the mean scores on case study-related questions were than the mean scores on paired control questions. Teaching grade 5 life science with a case study approach. C Improve your ability to communicate your knowledge of scientific concepts orally? Instruction related to control lessons was delivered using minimal slide-based lectures, with emphasis on textbook reading assignments accompanied by worksheets completed by students in and out of the classroom, and small and large group discussion of key points. Published online May 1. A recent survey of teachers who use case studies found that the topics most often covered in general biology courses included genetics and heredity, cell structure, cells and energy, chemistry of life, and cell cycle and cancer, suggesting that these topics should be of particular interest in studies that examine the effectiveness of the case study teaching method 8.
Presently, it is recommended that the use of case studies in teaching undergraduate general biology and other science courses be expanded, syudy for the teaching of capacious issues with real-world applications and in classes where development of written and oral communication skills are key objectives. Even when considering the inherent qualitative differences of course grades, these differences are negligible.
At the start of this study, relevant existing case studies were freely available from the National Center for Case Study Teaching in Science NCCSTS to address mitosis and meiosis and DNA structure and replication, but published case studies that appropriately addressed chemical bonds and osmosis and diffusion were not available.
Case studies also increased overall student perceptions of learning gains sz,o perceptions of learning gains specifically related to written and oral communication skills and the ability to grasp connections between scientific topics and their real-world applications.
All assessment questions were scored using a standardized, pre-determined rubric. Creating a better mousetrap: Completion of activities and discussion related to all case studies and control topics that were analyzed was conducted in the classroom, with the exception of the take-home portion of the osmosis and diffusion case study.
Three remaining courses are introduced during the fourth semester according to a previously indicated specialization. Student learning gains were assessed using a modified version of the SALG course evaluation szok.
The lack of a difference observed in the use of case studies from different sources should be interpreted with some degree of caution since only two sources were represented in this study, and each by only two cases.

Additionally, performance on quantitative learning assessments and student perceptions of learning gains were analyzed to determine whether reported perceptions of learning gains accurately reflect academic performance. Teaching science with case studies: Bonding with the tutor: Yee W, Bonney KM. This indicates that case studies are more effective than more commonly used, traditional s of content delivery at promoting learning of a variety of core concepts covered in general biology courses.
This study tested the hypothesis that case studies are more effective than classroom discussions and textbook reading at promoting learning of key biological concepts, development of written and oral communication skills, and comprehension of the relevance of biological concepts to everyday life. By the conclusion of this study, all four case studies had been peer-reviewed and accepted for publication by the NCCSTS http: RESULTS Teaching with case studies improves performance on learning assessments, independent of case study origin To evaluate the effectiveness of the dtudy study teaching method at promoting learning, student performance on examination questions related to material covered by case studies was compared with performance on questions that covered material addressed through classroom discussions and textbook reading.

Student perceptions of learning gains were assessed using a modified version of the Student Assessment of Learning Gains SALG course evaluation tool http: Szjo by the American Society for Microbiology.
In terms of examination performance, no significant difference between case studies produced by the instructor of the course chemical bonds and osmosis and diffusion and those produced by unaffiliated instructors mitosis and meiosis and DNA structure and replication was indicated by the Kruskal-Wallis one-way analysis of variance.

The results reported herein indicate that teaching with case studies results in significantly higher performance on examination questions about chemical bonds, osmosis and diffusion, mitosis and meiosis, and DNA structure and replication than that achieved by class discussions and textbook reading for topics of similar complexity. Additionally, faculty from a number of institutions have reported that using case studies promotes critical thinking, learning, and participation among students, especially in terms of the ability to view an issue from multiple perspectives and to grasp the practical application of core course concepts Dori YJ, Herscovitz O.
This article has been cited by other articles in PMC. To test the hypothesis that case studies produced specifically for this course by the instructor were more effective at promoting learning gains than topically relevant case studies published by authors not associated with this course, perceptions of learning gains were compared for each of the case studies.
This study also tested the hypothesis that the case study teaching method is more effective than class discussions and textbook reading at promoting learning gains associated with four of the most commonly taught topics in undergraduate general biology courses: The lack of a statistical difference between case studies therefore suggests that the effectiveness of a case study at promoting learning gains is not directly proportional to the difficulty of the concept covered.
A taxonomy for learning, teaching, and assessing: Importantly, there was no statistical difference in student performance on examinations attributed to the two case studies produced by the instructor of the course compared with the two case studies produced by unaffiliated instructors.

Compared with equivalent control questions about topics of similar complexity taught using class discussions and textbook readings, all four case studies produced statistically significant increases in the mean score on examination questions Fig.
