Objectives: In order to cope with the severe situation of the current COVID-19 epidemic and to provide better quality medical staffs for the Chinese medical system, as well as to promote the continuous development of clinical laboratory medicine towards standardization, normalization and technical automation. The application value of the lecture-based learning (LBL) and team-based learning (TBL) dual-track mode for internship in the clinical immunology subgroup of the laboratory department was evaluated in conjunction with the current undergraduate education mode of clinical laboratory technology in China, to provide a more efficient method for enhancing the comprehensive ability of interns in the laboratory department. Methods: A total of 61 laboratory interns from the grade 2017 of Southwest Medical University in China were collected and randomly divided into two groups: A and B. The group A adopted the traditional LBL teaching mode, and group B used the LBL-TBL dual-track teaching mode. The students' comprehensive abilities such as theoretical knowledge and experimental skills under the teaching models were compared. And finally the teaching effect was evaluated by theoretical assessment and questionnaire. Results: The satisfaction rate of group B was remarkably higher than that of group A in terms of analyzing skills, problems-solving ability and clinical operation (P < 0.05). There was no significant difference between the two groups involving in theoretical achievement levels (P > 0.05), but group B had a greater satisfaction rate than group A for enhancing theoretical knowledge acquisition. Conclusions: The LBL-TBL dual-track teaching mode plays a positive role for the internship in the laboratory department, which helps to improve the independent learning capability, analyzing skills and problems-solving ability. The LBL-TBL dual-track teaching method is worth further promotion in clinical immunology practice of the laboratory department.

BackgroundThis meta-analysis was conducted to systematically evaluate the impact of problem-based learning (PBL) and lecture-based learning (LBL) teaching models on students’ learning in surgical education.MethodsWe systematically searched the publications related to the application of PBL and LBL in surgical courses in PubMed, Embase, Web of Science and Cochrane Library databases, the last retrieval time is September 20, 2022. After screening the literature according to the inclusion and exclusion criteria, extracting data and evaluating the methodological treatment of the included studies, Stata 17.0 software was used to perform meta-analysis.ResultsNine studies were included totally. The results showed that compared with LBL, PBL was superior in clinical competence (SMD = 0.81, 95% CI: 0.12 ~ 1.49, P = 0.020) and student satisfaction (SMD = 2.13, 95% CI: 1.11 ~ 3.15, P < 0.0001) with significant differences. But the comprehensive scores (SMD = 0.26, 95% CI: -0.37 ~ 0.89, P = 0.421) and theoretical knowledge (SMD=−0.19, 95% CI: −0.71 ~ 0.33, P = 0.482) to PBL and LBL had no significant difference.ConclusionThis study showed that the PBL teaching model is more effective than the LBL teaching model in surgical education on the aspects of enhancing clinical competence and student satisfaction. However, further well-designed studies are needed to confirm our findings.

Simulation-Based Learning Combined with Case and Problem-Based Learning in the Clinical Education of Joint Surgery

Traditional education of clinical training mainly relies on a single mode of lecture-based learning (LBL), in which the teacher lectures and the students listen, and the teaching effect is often unsatisfactory. This study aims to explore the effect of simulation-based learning (SBL) combined with case and problem-based learning (CPBL) teaching mode in the clinical education of joint surgery. Through objective evaluation of joint surgery students' theoretical knowledge and clinical skills, and subjective evaluation of teaching quality by anonymous questionnaire, the teaching effects of LBL teaching mode, CPBL teaching mode and SBL combined with CPBL teaching mode in clinical teaching of joint surgery were compared. Sixty students who participated in the standardized training of residents in the Center for Joint Surgery, Southwest Hospital, Army University, China from March 2020 to September 2021 were selected and randomly divided into groups A, B, and C, with 20 students in each group. Group A adopted traditional LBL mode, group B adopted CPBL mode, and group C adopted SBL combined with CPBL mode. The scores of theoretical knowledge, clinical skills and total score of group C were (86.40 ± 9.76), (92.15 ± 4.49), (88.70 ± 5.75) points respectively, which were significantly higher than (78.80 ± 10.50), (86.60 ± 8.79), (81.92 ± 6.97) points in group B, and (80.50 ± 6.64), (85.35 ± 7.99), (82.44 ± 5.97) points in group A, the difference was statistically significant (p < 0.05). The scores of 5 self-evaluation items, i.e., learning interest, self-learning ability, problem-solving ability, clinical skills and comprehensive competency were (18.90 ± 1.22), (18.85 ± 1.01), (18.75 ± 1.13), (18.90 ± 1.22), (18.50 ± 1.02), (18.80 ± 0.81) points in group C, which were higher than (15.90 ± 1.41), (14.30 ± 2.47), (13.95 ± 2.01), (14.50 ± 1.63), (14.70 ± 1.38) points in group B, and (11.65 ± 2.90), (10.05 ± 1.69), (9.75 ± 1.67), (14.35 ± 1.90), (12.75 ± 2.12) points in group A, the difference was statistically significant (p <0.05). The satisfaction of students in group C (95.00%) was significantly better than that in group B (80.00%) and group A (65.00%), and the difference was statistically significant (p < 0.05). SBL combined with CPBL teaching mode can effectively improve the theoretical knowledge and clinical skills of the students, which could improve self-assessment and teaching satisfaction rate, and is worthy of application and promotion in the clinical teaching of joint surgery.

Online flipped classroom with team-based learning promoted learning activity in a clinical laboratory immunology class: response to the COVID-19 pandemic

BackgroundGiven the rapid development of clinical immunology technologies, students majoring in laboratory medicine should master the technological principles and application of clinical laboratory immunology. However, many are required to take online courses due to COVID-19 restrictions, which highlights the need to revisit teaching strategies. Recently, various medical education courses (such as Biochemistry, Physiology, etc.) have implemented the flipped classroom (FC) and team-based learning (TBL) methods, resulting in more positive teaching evaluations. To promote the students' mastery of the difficult knowledge effectively during the online teaching work, we evaluated the performance of online FC-TBL in a clinical laboratory immunology course.Methods Sixty-two third-year students from two classes majoring in Laboratory Medicine were recruited and divided into two groups, including one group with traditional lecture-based learning teaching strategy (LBL group) and the other group with LBL or online FC combined with TBL teaching strategy (FC-TBL group). We selected three chapters to conduct FC-TBL teaching in class. All participants took in-class quizzes and final examinations that targeted the same knowledge points. Finally, all participants completed anonymous questionnaires asking for their perceptions of the respective teaching models. In addition, we conducted a survey of teaching suggestions by a FC-TBL class of students majoring in Laboratory Medicine.ResultsThe FC-TBL group (vs LBL group) had significantly higher scores on the in-class quizzes and final examinations, and also reported high satisfaction with the FC-TBL model. These findings indicate that FC-TBL is suitable for clinical laboratory immunology, as the participants quickly gained essential knowledge. Specifically, FC-TBL helped to “increase learning motivation,” “promote self-directed learning skills,” “extend more related knowledge,” “enhance problem-solving abilities,” “enhance clinical reasoning abilities,” and “enhance communication skills.” For participants’ suggestions, 48.38% (15/31) students held positive attitude to FC-TBL teaching strategy compared to 25.81% (8/31) students who considered FC-TBL teaching strategy still needs continuous improvement, and 25.81% (8/31) students reported that they believed FC-TBL teaching strategy was perfect and no further suggestions.ConclusionsOnline FC-TBL effectively enhanced learning activity among students of a clinical laboratory immunology course. This is particularly useful in the COVID-19 context.

Application of symptom-based mind mapping combined with PBL teaching method in emergency trauma standardized resident training in MDT model.

Explore the feasibility and effectiveness of accepting mind mapping combined with problem-based learning (PBL) teaching method in the standardized training of emergency surgery residents in the multi-disciplinary team (MDT) model of emergency trauma. Eighty-nine doctors under training who rotated in the Department of Emergency Surgery of the First Affiliated Hospital of Anhui Medical University from January 2021 to January 2022 were selected as the study subjects, and randomly divided into a group receiving mind mapping combined with PBL teaching and a group receiving traditional lecture-based learning teaching. Mini-clinical evaluation exercise (Mini-CEX), direct observation of procedural skills (DOPS), teaching adherence, and satisfaction assessments were completed at the time of discharge from the department. There were no significant differences between the observation and control group trainees in terms of gender, age, education, and entry grades. Both groups of doctors were better able to participate in their respective teaching modes and made significant progress. The participants in the observation group had significantly higher Mini-CEX, DOPS, and teaching satisfaction scores than the control group (P < .05). Under the MDT model of emergency trauma, the combination of mind mapping and PBL teaching can improve the comprehensive clinical ability of the trainees more than participating in the traditional lecture-based learning teaching, which is worth promoting and implementing in the clinical standardized training.

Classroom Resource Optimization of the English Four-Step Model Based on Deep Learning

The existing LBL (lecture-based learning) and CBL (case-based learning) teaching modes of English majors in colleges and universities do not contribute to cultivating students’ inquisitive thinking and independent learning ability, whereas the problem-centered PBL (problem-based learning) teaching mode can precisely make up for these shortcomings. This study firstly constructed a PBL “four-step” teaching mode and then realized the innovative application of PBL teaching model in the teaching of English majors in new universities. Then, we designed a method of English classroom resource optimization based on IMOCS-BP neural network, and then, the classroom resource optimization reconstructs the teaching process with unique connotation essence. The experiments show that the BL “four-step” teaching model is designed to achieve the four key elements of “flexible English learning environment, transformed learning the culture, customized content and professional educators”; the designed neural network has optimized the English classroom resources.

Flipped classroom improves nursing students' theoretical learning in China: A meta-analysis.

ObjectiveAt present, current didactic teaching delivery method help nursing students apply theory to clinical situations in an inefficient way. The flipped classroom (FC), a novel teaching mode emphasizing self-study and critical thinking, has generated interest in nursing education in China. However, there are a gap in the literature and no consistent outcomes of current studies which compared FC and lecture-based learning (LBL), and no systematic review has comprehensively compared theoretical scores as an affected outcome in FC versus LBL modes.MethodsIn this review, we analyze flipped-learning nursing students’ scores, and aim to assess the efficacy and provide a deeper understanding of the FC in nursing education. Following the inclusion criteria, articles were obtained by searching PubMed, Embase and Chinese data, including the China National Knowledge Infrastructure, Wanfang Data, and VIP database until 3 January 2020. Data were extracted from eligible articles and quality was assessed. A meta-analysis was then performed using a random effects model with a standardized mean value (SMD) and a 95% confidence interval (CI).32 studies were included after reviewing 2,439 citations. All studies were randomized controlled trials (RCTs). The FC theoretical knowledge scores in FC were significantly positively affected compared to those of the traditional classroom (SMD = 1.33, 95% CI: 1.02–1.64; P < 0.001). In addition, 23 studies reported skill scores, indicating significant difference between the FC mode and LBL mode (SMD = 1.58, 95%CI: 1.23–1.93; P < 0.001).ConclusionsThe results of this meta-analysis suggest that compared to the LBL teaching method, the FC mode dose significantly improve Chinese nursing students’ theoretical scores. However, the problems of heterogeneity and publication bias in this study need to be remedied high-quality future studies.

Exploration of Dermato-venereology Teaching Combining the Problem-oriented Teaching Method with Computer Technology

The problem-oriented teaching approach (PTM) is a teaching approach that focuses on problem-oriented study and teaching through identification and solving of problems. Since the 1990s with teh development of computer, some medical schools and colleges in China and Southeast Asia have started to apply the problem-based teaching approach and computer technology gradually. Currently, it is still in the initial and exploratory stage in China, and the lecture-based learning (LBL) plays a leading role in medical teaching. PTM is distinctly different from the traditional LBL teaching model where the teachers give lectures and the students are spoon-fed in classes. It has broken through the traditional teaching confinement based on explanations by teachers, and students can take the initiative to analyze and solve problems pertinently in teaching.

Practice and exploration of lecture-based learning combined with problem-based learning in pathophysiology teaching

Objective To explore the application of lecture-based learning (LBL) combined with problem-based learning (PBL) in the teaching of pathophysiology case analysis. Methods The subjects were 62 preventive medicine majors of Grade 2015 and 68 stomatology majors of Grade 2015, and the course content was case analysis. PBL teaching was implemented in the preventive medicine major group and LBL+PBL teaching was implemented in the stomatology major group. Both groups received 6 class hours, among which the LBL+PBL teaching hours were allocated 2 class hours for LBL and 4 class hours for PBL. In addition, the questionnaire was used to evaluate the teaching effects between the two groups, and the descriptive analysis was used to evaluate relevant data lines. Results Eleven students (17.742%) from the preventive medicine major group chose PBL teaching, while 38 students (92.647%) in the stomatology major group held a very positive attitude towards LBL+PBL teaching. It can be seen that the recognition degree of LBL+PBL teaching in the stomatology major group was higher than that of PBL teaching in the preventive medicine major group. Conclusion Since students have received LBL teaching mode for a long time, it is difficult to accept and adapt to PBL teaching in terms of thinking and teamwork. Therefore, in the course of pathophysiology case analysis, LBL+PBL teaching shows a good effect, which is worthy of further exploration.

Using integrated problem- and lecture-based learning teaching modes for imaging diagnosis education

BackgroundThere are two parts included in traditional imaging diagnosis teaching: theoretical lessons and experimental lessons. Most of the time, the experimental lesson is a review of the theoretical lesson. The teacher is the centre of the course and students are passive learners. Thus, in this study we included the patient problem of the imaging centre in our imaging diagnosis education. The traditional theoretical lessen was used to discuss prior knowledge, the discussion and analysis of patient problems was arranged under class, and the experimental lesson was used to synthesize and test the newly acquired information. The aim of this study is to determine whether or not integration of problem- and lecture-based learning teaching modes in imaging diagnosis education was associated with a good teaching effect. Forty-six of sixty students (76.7%) like integrated problem- and lecture-based learning teaching mode and 53 of 60 students (88.3%) think that integrated problem- and lecture-based learning teaching mode can make their ability of self-study be improved.MethodsSixty students participated in a prospective study with a two-phase cross-over design. All of the students were divided into 2 groups of 30 each. In the first term, the first group participated in an integration of the problem- and lecture-based learning teaching mode, whereas students in the second group underwent the lecture-based learning teaching mode alone. During the second term, the teaching modes were exchanged between the two groups. A close-exam and survey were used to evaluate the teaching effect, and the data were analysed means of analysis of variance with a two-phase cross-over design and a χ2 test with a 2-tailed α of 0.05.ResultsThere was a statistically significant difference in the test scores between the integration of the problem- and lecture-based learning teaching mode and the lecture-based learning teaching mode alone (P < 0.05). The integration of problem- and lecture-based learning teaching mode was well-appraised.ConclusionIntegration of the problem- and lecture-based learning teaching modes in teaching imaging diagnosis education resulted in a good teaching effect.
