Flipped classroom(FC) and problem-based learning(PBL) are well-known education methods that can be integrated into ophthalmology education to improve students' competence level and promote active learning. Methods: We used a mixed teaching methodology that integrated a FC and PBL into a 1-week ophthalmology clerkship for 72 fourth-year medical students. The course includes two major sessions: FC session and PBL session, relying on clinical and real-patient cases. Written examinations were set up to assess students' academic performance and questionnaires were designed to evaluate their perceptions. Results: The post-course examination results were higher than the pre-course results, and many students gained ophthalmic knowledge and learning skills to varying levels. Comparison of pre-and post-course questionnaires indicated that interests in ophthalmology increased and more students expressed desires to be eye doctors. Most students were satisfied with the new method, while some suggested the process should be slower and the communication with their teacher needed to strengthen.Conclusions: FC and PBL are complementary methodologies. Utilizing the mixed teaching meth of FC and PBL was successful in enhancing academic performance, student satisfactions and promoting active learning.展开更多

The respondents of this research were the two sections comparable with each other who was enrolled in the subject Navigation 3. There were 60 student respondents composed of 30 in the experimental group and 30 in the control group. A validated three item teacher-made problem solving test with 10 points for each correct answer was used as an instrument. The dependent variable was the scores in Navigation 3 and independent variable was the PBL approach. The statistical tools used were mean, standard deviation, Mann-Whitney test, and Wilcoxon-Signed ranks test set at 0.05 level of significance. The effect size was computed to determine the effectiveness of the PBL approach in terms of students＇ performance in Navigation 3. Results showed that in the pretest, though the experimental group had a higher mean than the control group, the Mann-Whitney test showed that the mean scores of the two groups were comparable because the significant value was greater than 0.05. When the treatment was introduced, findings showed that there were significant differences in the Navigation 3 performance in the pretest and posttest of experimental and control groups as well as in the posttests of both groups. It could be inferred that the better performance of the experimental group could be attributed to the intervention where the students were actively involved in the learning process.展开更多

Methods: This study was a one group pre- and post-test design. Twenty five students received a 5-hour SIM-PBL program focused on nursing care of clients with hypertension. A newly developed self-report questionnaire was used to assess SE in four areas of the nursing process with a scale of 0 (not at all confident) to 10 (totally confident). The four areas were subjective data assessment, physical examination, prioritizing nursing care and health promotion advices. Results: At baseline, students’ SE ranged from 5.5 ± 1.4 (prioritizing nursing care) to 7.6 ± 1.4 (subjective data assessment). After SIM-PBL education, all areas of nursing process presented statistically significant improvements of SE. The improvements were most noticeable in prioritizing nursing care. Conclusion: The SIM-PBL module was effective in improving the students’ self-efficacy in the nursing process for patients with hypertension. Further studies are recommended in developing SIM-PBL modules for diverse nursing topics and evaluating their effectiveness in various aspects of students’ competency.展开更多

When the treatment was introduced, findings showed that there were significant differences in the Navigation 3 performance in the pretest and posttest of experimental and control groups as well as in the posttests of both groups. It could be inferred that the better performance of the experimental group could be attributed to the intervention where the students were actively involved in the learning process.

文摘Mathematical modeling course has been one of the fast development courses in China since 1992,which mainly trains students’innovation ability.However,the teaching of mathematical modeling course is quite difficult since it requires students to have a strong mathematical foundation,good ability to design algorithms,and programming skills.Besides,limited class hours and lack of interest in learning are the other reasons.To address these problems,according to the outcome-based education,we adopt the problem-based learning combined with a seminar mode in teaching.We customize cases related to computer and software engineering,start from simple problems in daily life,step by step deepen the difficulty,and finally refer to the professional application in computer and software engineering.Also,we focus on ability training rather than mathematical theory or programming language learning.Initially,we prepare the problem,related mathematic theory,and core code for students.Furtherly,we train them how to find the problem,and how to search the related mathematic theory and software tools by references for modeling and analysis.Moreover,we solve the problem of limited class hours by constructing an online resource learning library.After a semester of practical teaching,it has been shown that the interest and learning effectiveness of students have been increased and our reform plan has achieved good results.
文摘Introduction: The purposes of this study were to describe the simulation integrated with problem-based learning (SIM-PBL) module to educate the nursing process for clients with hypertension and to evaluate its effectiveness on nursing students’ self-efficacy (SE). Methods: This study was a one group pre- and post-test design. Twenty five students received a 5-hour SIM-PBL program focused on nursing care of clients with hypertension. A newly developed self-report questionnaire was used to assess SE in four areas of the nursing process with a scale of 0 (not at all confident) to 10 (totally confident). The four areas were subjective data assessment, physical examination, prioritizing nursing care and health promotion advices. Results: At baseline, students’ SE ranged from 5.5 ± 1.4 (prioritizing nursing care) to 7.6 ± 1.4 (subjective data assessment). After SIM-PBL education, all areas of nursing process presented statistically significant improvements of SE. The improvements were most noticeable in prioritizing nursing care. Conclusion: The SIM-PBL module was effective in improving the students’ self-efficacy in the nursing process for patients with hypertension. Further studies are recommended in developing SIM-PBL modules for diverse nursing topics and evaluating their effectiveness in various aspects of students’ competency.
文摘This thesis took students from Grade one of Xuancheng No.3 Middle High School as the research objects,mainly employing the classroom observation,the questionnaire,and test to investigate the effect of problem-based learning method in English grammar teaching.The findings are as follows:(a)the scores of students in the experimental class obviously improved;and(b)compared with the traditional teaching method,the application of problem-based learning method in grammar teaching can stimulate students’interest in learning.To sum up,this method can improve students’English competence and learning interest significantly,which suggests it can be applied in grammar teaching.
文摘Problem-based Learning has been implemented in schools in China for nearly ten years, but there are still some problems in its implementation, especially in English Problem-based Learning, its management and the requirements of English teachers. This paper puts forward rational cognition on these problems.
文摘Objectives: The study’s aims to determine and assess the application of problem-based learning to undergraduate nursing students. Background: Nursing students are the upcoming health care delivery system;according to their standard of learning, it will affect their clinical training. Method: The study design is a case study review, the data was collected using many articles related to problem-based learning collected from E-books and E-journals websites like CINAHEL, Google Scholar, etc. After that, the data was analyzed and evaluated related to the application of problem-based learning on undergraduate nursing students. Result: The result appeared that most of the research proved and supported that the application of problem-based learning is effective for undergraduate nursing students, and students can solve patients’ problems in a better way. Conclusion: In conclusion, problem-based learning is an essential part of the nursing diagnosis process that will increase knowledge, and performance, and merge it with the nursing concepts.
