Can learning style predict student satisfaction with different instruction methods and academic achievement in medical education?

The curriculum of our medical school has a hybrid structure including both traditional training (lectures) and problem-based learning (PBL) applications. The purpose of this study was to determine the learning styles of our medical students and investigate the relation of learning styles with each of satisfaction with different instruction methods and academic achievement in them. This study was carried out with the participation of 170 first-year medical students (the participation rate was 91.4%). The researchers prepared sociodemographic and satisfaction questionnaires to determine the characteristics of the participants and their satisfaction levels with traditional training and PBL. The Kolb learning styles inventory was used to explore the learning styles of the study group. The participants completed all forms at the end of the first year of medical education. Indicators of academic achievement were scores of five theoretical block exams and five PBL exams performed throughout the academic year of 2008-2009. The majority of the participants took part in the "diverging" (n = 84, 47.7%) and "assimilating" (n = 73, 41.5%) groups. Numbers of students in the "converging" and "accommodating" groups were 11 (6.3%) and 8 (4.5%), respectively. In all learning style groups, PBL satisfaction scores were significantly higher than those of traditional training. Exam scores for "PBL and traditional training" did not differ among the four learning styles. In logistic regression analysis, learning style (assimilating) predicted student satisfaction with traditional training and success in theoretical block exams. Nothing predicted PBL satisfaction and success. This is the first study conducted among medical students evaluating the relation of learning style with student satisfaction and academic achievement. More research with larger groups is needed to generalize our results. Some learning styles may relate to satisfaction with and achievement in some instruction methods.     

The effects of discovery learning in a lower-division biology course

This study investigated discovery learning pedagogy and its effects on students' achievement and attitudes toward instruction in a lower-division biology course, entitled Structure and Function of Organisms. Instruction was primarily lecture-based but included four discovery learning activities. Results indicate that students had greater achievement on content learned through discovery methods than lecture-based instruction. Findings regarding students' attitudes toward discovery-based instruction suggest that students enjoyed active, discovery-based problems, believed that discovery helped them gain an understanding of the material and helped them to develop skills that could be used in other courses. The study presented here shows that a moderate amount of discovery learning used in combination with traditional methods of instruction may be an effective means for promoting students' achievement.     

Ways of coping as predictors of satisfaction with curriculum and academic success in medical school

The purpose of the present study was to determine the coping strategies of medical students and to investigate the effects of coping strategies on student satisfaction and academic achievement with different instruction methods. A total of 152 medical students was followed throughout the first 2 yr of medical education between 2008 and 2010. Students completed a sociodemographic questionnaire and revised form of the Ways of Coping questionnaire both at the beginning of the first year and at the end of the second year. These forms provided data about the characteristics and main coping strategies (problem focused or emotion focused) of the students and revealed the change over time. At the end of the second year, participants also completed a satisfaction questionnaire asking their satisfaction with lectures, problem-based learning, and practicals. The authors used block, problem-based learning, and practical exam scores of the students attained in the past 2 yr as academic achievement indicators. No sociodemographic variable was related to coping strategy. The majority of students (80.9%) adopted problem-focused coping. A shift occurred in the main coping strategies of some students in both sides. Problem-focused coping scores decreased over time. Problem-focused coping positively correlated with satisfaction with practicals and practical exam scores, whereas emotion-focused coping showed the same correlation negatively. The main coping strategy also predicted satisfaction and exam success in practicals. In conclusion, a main coping strategy may be helpful to predict student satisfaction and academic achievement with some student-centered instruction methods. Determining undesired coping strategies may provide an opportunity for intervention to prevent relevant dissatisfaction and failure.     

Teaching biology students to think divergently

A group of first-year biology students (N = 16) at a tertiary institution was instructed in techniques designed to increase their divergent thinking skills and thus their ability to generate ideas about issues in biology. A comparison was made between the performance of this group and a control group (N = 15) who had not received any training. The experimental group obtained significantly higher scores than the controls on post-test measures of divergent thinking for both general and biological topics. These differences in the biology measures were maintained in a delayed post-test. Results were interpreted as supporting the need for, and effectiveness of, simple techniques designed to improve thinking skills, specifically in biology.

Metacognitive inquiry activities for instructing the central dogma concept: ‘button code’ and ‘beaded bracelet making’

ABSTRACT

The central dogma of biology is difficult to learn because its microscopic processes cannot be visualized. This study aimed to devise two inquiry activities: ‘Button Code’ and ‘Beaded Bracelet Making,’ involving the concepts of DNA replication and protein synthesis based on the Metacognitive Learning Cycle (MLC) for students, and to explore the effectiveness of concept learning of the central dogma, how students’ metacognition may be expressed, and students’ perceptions of their inquiry performance. We developed a ‘Concept journal’ including metacognitive scaffolds, and employed the ‘Central Dogma Achievement Test’ as a tool for the above purpose. A total of 18 junior high school students participated in this inquiry course instructed by two of the authors. The results showed that students’ achievement performance was significantly improved on the whole, the students’ metacognition was expressed during the process of inquiry with scaffolding, and most students gave positive responses about their learning performance. According to the results, this inquiry course could develop students’ comprehension of the central dogma concept, and give students opportunities to practice metacognition that might lead to effective learning in inquiry activities. The implications and expandability of this course are discussed.     

Peer-Assisted Learning in a Gross Anatomy Dissection Course

Peer-assisted learning encourages students to participate more actively in the dissection process and promotes thoughtful dissection. We implemented peer-assisted dissection in 2012 and compared its effects on students’ self-assessments of learning and their academic achievement with those of faculty-led dissection. All subjects performed dissections after a lecture about upper-limb gross anatomy. Experimental group (n = 134) dissected a cadaver while guided by peer tutors who had prepared for the dissection in advance, and control group (n = 71) dissected a cadaver after the introduction by a faculty via prosection. Self-assessment scores regarding the learning objectives related to upper limbs were significantly higher in experimental group than in control group. Additionally, experimental group received significantly higher academic scores than did control group. The students in peer-assisted learning perceived themselves as having a better understanding of course content and achieved better academic results compared with those who participated in faculty-led dissection. Peer-assisted dissection contributed to self-perception and to the ability to retain and explain anatomical knowledge.

Teaching Tree Thinking to College Students: It’s Not as Easy as You Think

The ability to understand and reason with tree-of-life diagrams (i.e., cladograms), referred to as tree thinking, is an essential skill for biology students. Yet, recent findings indicate that cladograms are cognitively opaque to many college students, leading them to misinterpret the information depicted. The current studies address the impact of prior biological background and instruction in phylogenetics on students?? competence at two foundational tree-thinking skills. In Study 1, college students with stronger (N?=?52) and weaker (N?=?60) backgrounds in biology were asked to (a) identify all the nested clades in two cladograms and (b) evaluate evolutionary relatedness among taxa positioned at different hierarchical levels (two questions) and included in a polytomy (two questions). Stronger-background students were more successful than weaker-background students. In Study 2, a subset of the stronger-background students (N?=?41) who were enrolled in an evolution class subsequently received two days of instruction on phylogenetics. As expected, these students?? tree-thinking skills generally improved with instruction. However, although these students did very well at marking the nested clades, fundamental misinterpretations of relative evolutionary relatedness remained. The latter was especially, although not exclusively, the case for taxa included in a polytomy. These results highlight the importance of teaching cladistics, as well as the need to tailor such instruction to the difficulties students have learning key macroevolutionary concepts.     

PBL教学法在医学寄生虫学教学中的几点体会

目前全国高等医学院校医学寄生虫学学时大大减少,有的院校列为考查课,有的列为选修课。在此情况下,医学寄生虫学实验所占学时更是少之又少,如何利用好有限课时,使学生最大限度地吸收、掌握教学内容,已成为摆在高校师生面前的一道难题。传统的教学方法以讲授为主,容易忽视学生学习的主动性和积极性。而应用了PBL(problem based learning)教学法,其基本要点是以学生为中心、基于问题、综合地、相互合作和交互式地学习,有助于培养和提高学生在自学、实验技术、团队合作、分析问题和解决问题等方面的能力,激发学生学习的积极性和主动性。     

Pre-academic and early academic achievement in children with velocardiofacial syndrome (del22q11.2) of borderline or normal intelligence

School-aged children with del22q11.2 tend to show a typical learning and neuropsychological profile, which is characterised by a VIQ-PIQ discrepancy (in favour of the VIQ) and significantly better scores for reading (decoding) and spelling compared to mathematics. To the best of our knowledge, there exists no systematic research on the pre-academic and early academic skills that might underpin these learning difficulties. The purpose of the current study was to investigate more systematically these pre-academic and early academic skills in borderline to normal intelligent (FSIQ > 70) children with del22q11.2 in the last year of kindergarten and first grade of primary school in Flanders. In the kindergarten group, meta-linguistic awareness and counting skills were examined. In the group of first graders, children were tested on reading, spelling and mathematics. Thirteen children (mean age: 6 years 4 months (SD = 0.84); 9 boys, 4 girls) participated in this study. In the present study, there were no differences in intelligence and academic outcomes between boys and girls, and no differences in IQ and academic achievement between children with cardiac defects or severe velopharyngeal insufficiency (VPI) and children without these deficits. With regard to pre-academic achievement in general, a characteristic profile with clearly better results for meta-linguistic awareness in comparison to counting skills was found, but this difference is not statistically significant. Concerning early academic achievement, children with del22q11.2, as a group, perform (despite their somewhat lower general intelligence) on average compared with their age-related peers. However, at an individual level--especially within the domain of counting skills and mathematics--there is a wide variability, with some children showing remarkable learning difficulties already at an early age.     

PBL结合CBL教学法在神经病学教学中的应用

目的:探讨"以问题为基础"(problem-based learning,PBL)教学法结合"以病例为基础"(case-based learning,CBL)教学法在神经病学教学中的应用效果。方法:选取第四军医大学临床医学专业5年制学生180人,随机分为观察组(90人)和对照组(90人)。观察组采取PBL结合CBL教学法完成神经病学教学任务,对照组采取传统的授课式教学法完成教学任务,采用调查问卷和理论考试评估教学效果。用SPSS16.0软件进行统计学分析,计量资料采用均数±标准差表示,组间比较采用单因素方差分析;计数资料的组间比较采用卡方检验,以P0.05为差异有统计学意义。结果:观察组在学习积极性、自学能力、临床思维培养、分析和解决问题能力、语言表达和沟通能力、团队协作能力及学习效率等方面的培养均明显优于对照组;前者的考试成绩(87.2±6.4分)亦明显高于后者(77.4±7.8分),组间差异均有统计学意义(P0.05)。结论:PBL结合CBL教学法可激发学生的学习兴趣,提高考试成绩,对提升临床神经病学的教学质量具有积极意义。     

Using Team-Based Learning to Teach Grade 7 Biology: Student satisfaction and improved performance

Team-based learning (TBL) is an innovative form of collaborative learning. The purpose of this study was to evaluate TBL’s effect on the performance and satisfaction of grade 7 students in biology in a private school in Lebanon, as well as teachers’ willingness to implement this new methodology. An exploratory study was performed whereby two biology units were taught to two groups of students using either TBL (60 students) or traditional lecture-based instruction (30 students). Later, a summative test was administered to evaluate students’ performance. Students’ attitudes were evaluated using a questionnaire and teachers’ classroom observations. Finally, science teachers’ willingness to try TBL in their classes was assessed using a questionnaire (14 teachers). Results showed that underachievers taught according to TBL did better than underachievers taught with the lecture-based approach. The majority of students enjoyed TBL and found it useful and fun. Finally, science teachers agreed that TBL is a good alternative to the traditional lecture-based method.     

How Health Behaviors Relate to Academic Performance via Affect: An Intensive Longitudinal Study

Objective

This intensive longitudinal study examined how sleep and physical activity relate to university students’ affect and academic performance during a stressful examination period.

Methods

On 32 consecutive days, 72 first-year students answered online questionnaires on their sleep quality, physical activity, positive and negative affect, learning goal achievement, and examination grades. First-year university students are particularly well-suited to test our hypotheses: They represent a relatively homogeneous population in a natural, but controlled setting, and simultaneously deal with similar stressors, such as examinations. Data were analyzed using multilevel structural equation models.

Results

Over the examination period, better average sleep quality but not physical activity predicted better learning goal achievement. Better learning goal achievement was associated with increased probability of passing all examinations. Relations of average sleep quality and average physical activity with learning goal achievement were mediated by experienced positive affect. In terms of day-to-day dynamics, on days with better sleep quality, participants reported better learning goal achievement. Day-to-day physical activity was not related to daily learning goal achievement. Daily positive and negative affect both mediated the effect of day-to-day sleep quality and physical activity on daily learning goal achievement.

Conclusion

Health behaviors such as sleep quality and physical activity seem important for both academic performance and affect experience, an indicator of mental health, during a stressful examination period. These results are a first step toward a better understanding of between- and within-person variations in health behaviors, affect, and academic performance, and could inform prevention and intervention programs for university students.     

CBL联合PBL教学方法在创伤外科学教学中的初步探究

Peer instruction enhanced meaningful learning: ability to solve novel problems

Students must be able to interpret, relate, and incorporate new information with existing knowledge and apply the new information to solve novel problems. Peer instruction is a cooperative learning technique that promotes critical thinking, problem solving, and decision-making skills. Therefore, we tested the hypothesis that peer instruction enhances meaningful learning or transfer, defined as the student's ability to solve novel problems or the ability to extend what has been learned in one context to new contexts. To test this hypothesis, our undergraduate exercise physiology class of 38 students was randomly divided into two groups: group A (n = 19) and group B (n = 19). A randomized crossover design in which students either answered questions individually or during peer instruction was used to control for time and order effects. The first factor that influences meaningful learning is the degree of mastery of the original material. Importantly, peer instruction significantly enhanced mastery of the original material. Furthermore, the student's ability to solve novel problems was significantly enhanced following peer instruction. Thus pausing two to three times during a 50-min class to allow peer instruction enhanced the mastery of the original material and enhanced meaningful learning, i.e., the student's ability to solve novel problems.     

Evaluation of the teaching strategy of cardiovascular system in a problem-based curriculum: student perception

It is generally acknowledged that an integrated approach to teaching cardiovascular system (CVS) is clinically relevant. However, very little attention has been paid with respect to student perception of teaching CVS in an integrated problem-based curriculum. A questionnaire on the feedback and perception of medical students (n = 60) to their learning experience of CVS exposed early in the problem-based integrated curriculum at the Arabian Gulf University (AGU) was used. The average percentage scores of positive student responses to items related to knowledge was 62.7%, to integration was 87.3%, and to skills was 77.1%. A significant positive correlation was observed among skills and knowledge (r = 0.408, P = 0.002), skills and integration (r = 0.506, P < 0.000), and integration and knowledge (r = 0.294, P = 0.028). The lowest individual percentage score related to knowledge items was given to the role of resource sessions in understanding difficult concepts (32.7%). Interestingly, 90.7% of the students were aware of the presence of gaps in their knowledge. On the other hand, 92.7% of students expressed their satisfaction with the study experience of CVS in the integrated problem-based approach. These results indicate that students overall achieved satisfactory learning outcome during the study of CVS in the problem-based integrated curriculum at AGU. The study also points out issues where improvement and fine tuning of the educational system can take place.     

Effects of different forms of physiology instruction on the development of students' conceptions of and approaches to science learning

The purpose of this study was to investigate students' conceptions of and approaches to learning science in two different forms: internet-assisted instruction and traditional (face-to-face only) instruction. The participants who took part in the study were 79 college students enrolled in a physiology class in north Taiwan. In all, 46 of the participants were from one class and 33 were from another class. Using a quasi-experimental research approach, the class of 46 students was assigned to be the "internet-assisted instruction group," whereas the class of 33 students was assigned to be the "traditional instruction group." The treatment consisted of a series of online inquiry activities. To explore the effects of different forms of instruction on students' conceptions of and approaches to learning science, two questionnaires were administered before and after the instruction: the Conceptions of Learning Science Questionnaire and the Approaches to Learning Science Questionnaire. Analysis of covariance results revealed that the students in the internet-assisted instruction group showed less agreement than the traditional instruction group in the less advanced conceptions of learning science (such as learning as memorizing and testing). In addition, the internet-assisted instruction group displayed significantly more agreement than the traditional instruction group in more sophisticated conceptions (such as learning as seeing in a new way). Moreover, the internet-assisted instruction group expressed more orientation toward the approaches of deep motive and deep strategy than the traditional instruction group. However, the students in the internet-assisted instruction group also showed more surface motive than the traditional instruction group did.     

What Do Secondary Students Really Learn during Investigations with Living Animals? Parameters for Effective Learning with Social Insects

Exemplary for social insects, Temnothorax ants allow for various hands-on investigations in biology classes. The aim of this study was to provide a quantitative and qualitative analysis of secondary school students’ learning achievement after teaching units with ants lasting between one and six weeks. The questionnaires included transfer and factual knowledge tasks divided into eight fields of knowledge. Students (N = 459) from 22 classes participated in the study and received different treatments: The experimental group (n = 366) started their investigations by initial observation using stereo microscopes, while the control group (n = 93) conducted ant research without this introductory teaching unit. We investigated the influence of class level, gender and time period of participation on knowledge acquisition. Independent of class level, factual learning achievement was observed for all fields of knowledge except ecology. We did not find a positive correlation between time period of participation and basic ant knowledge acquisition. The findings suggest that ant research may be implemented within the framework of a progressive curriculum for all secondary school students. However, attentive and detailed observation of ant colonies with stereo microscopes and continuous repetition of technical terms seem to be inevitable preconditions for learning achievement.
