Linking teaching and research in an undergraduate course and exploring student learning experiences

ABSTRACT

In this case study, we first describe how teaching and research are linked in a master’s course on tissue engineering. A central component of the course is an authentic research project that the students carry out in smaller groups and in collaboration with faculty. We then explore how the students experience learning in this kind of discovery-oriented environment. Data were collected through a survey, reflective writing, and interviews. Using a general inductive approach for qualitative analysis, we identified three themes related to the students’ learning experiences: learning to navigate the field, learning to do real research, and learning to work with others. Overall, the students strongly valued learning in a discovery-oriented environment and three aspects of the course contributed to much of its success: taking a holistic approach to linking teaching and research, engaging students in the whole inquiry process, and situating authentic problems in an authentic physical and social context.     

Impact on student teachers' conception of learning and teaching from studying a course in educational psychology

This study investigates changes in the conceptions of learning and teaching among undergraduate student teachers. A qualitative content analysis of essays using metaphors to describe learning and teaching written by 256 students at the beginning and end of an educational psychology course was used as the main research procedure. It was found that there was an increase in the share of students that see learning and teaching from a cognitive-constructivist perspective and a decrease in the share that see learning and teaching from a behaviourist perspective by the end of the course. In addition, the study revealed that the coherence in the nature of the metaphors describing learning and teaching increased by the end of the course. However, there was practically no increase in the number of essays describing learning from a socio-constructivist perspective, a fact that points to a need to pay more attention to the manifestations of learning in different communities of students, that is, to a relevant knowledge that teachers need in their everyday work.     

Improved learning efficiency and increased student collaboration through use of virtual microscopy in the teaching of human pathology

The implementation of virtual microscopy in the teaching of pathology at the Bloomington, Indiana extension of the Indiana University School of Medicine permitted the assessment of student attitudes, use and academic performance with respect to this new technology. A gradual and integrated approach allowed the parallel assessment with respect to both the virtual and optical microscopes. Student survey data indicated that the virtual imaging technology was enthusiastically received, and aggregate grade comparisons with the previous classes showed no decrease in content mastery. Survey questions assessing a variety of parameters reveal improved time and resource utilization, as well as increased student collaboration. Even so, 50% of the respondents indicated having both optical and virtual microscopes available was preferable. Anat Sci Ed 1:240–246, 2008. © 2008 American Association of Anatomists.     

Intelligent design: student perceptions of teaching and learning in large social work classes

Research into the effects of large classes demonstrates that students are disadvantaged in terms of higher order learning because interactions between teachers and students occur at lower cognitive levels. This has significance for social work education, with its emphasis on the development of critical thinking and problem solving, both higher order cognitive skills. This paper reports on quantitative and qualitative research that explored social work students’ perceptions of different teaching and learning strategies in a large mental health course designed with reference to principles of student‐centred learning and constructive alignment. Findings revealed that well‐integrated design, relevance to the real world and teacher enthusiasm were seen as most useful by students, rather than particular learning strategies per se. Higher satisfaction ratings and grades were also associated with this student‐centred course compared with an earlier traditional lecture‐style course. The paper concludes that design based on the interplay between diverse learning activities, including lecture input, strengthened the student‐centred orientation of learning and recommends further research that compares learning outcomes associated with these contrasting approaches to professional education.     

Application of experiential learning to improve student engagement and experience in a mechanical engineering course

ABSTRACT

This paper introduced how a mechanical engineering course was redesigned by applying experiential learning theory to improve student engagement and learning experience. Design of machine elements has been considered by students to be a difficult course. Traditional teaching methods tend not to be effective in engaging students. Experiential learning is a philosophy of learning by doing. In applying an experiential learning approach to the course, the design project and workshop activities were restructured in such a way that students were engaged in direct experience and focused reflection to construct knowledge. By exploring a physical gearbox model, working on subtasks for the design project, having group discussions, raising questions, getting feedback, and moving forward for next subtasks, students experienced the learning cycles of ‘DO, OBSERVE, THINK, and PLAN’ many times. Course survey results showed that application of experiential learning helped to improve student engagement and learning experience significantly.     

A detailed research study of learning and teaching core chemical engineering to a high standard in a mixed-ability small class in industry

A detailed study of learning and teaching (L&;T) of chemical engineering distillation to a mixed-ability small class of 13 students who are ordinarily full-time in-house employees in industry is reported. The course consisted of 9?×?2-h lectures (18 hours) and 9?×?2-h tutorials (18 hours). It was delivered over nine business days in situ in an established distillery. The purpose was to (re)learn core distillation of ethanol–water mixes at the level of higher education of a bachelor programme. There was 90% broad agreement that the course encouraged more learning. Students (40%) felt the course was too mathematical, however. Pointedly, there was good agreement (63%) that the course stimulated communication with each other professionally, and customers of the distillery. Results overall provide good evidence that students valued their L&;T. The experimental design(s) could be readily applied to a range of fields of knowledge.     

Paradoxical tensions in creating a teaching and learning space within a graduate education course on spirituality

Much has been written recently about inclusive learning environments in higher education. Most of this writing has unproblematically assumed a simple link between inclusion and access to institutions. In this paper I suggest that inclusive learning environments need to be reconceptualised as contexts within which a 'democratisation of knowledge' occurs. I draw upon my experience as a tutor on a professional development course for university lecturers to explore this reconceptualisation, looking in particular at issues to do with experiential knowledge, gender and sexuality.     

An experiment for teaching chamical kinetics in chemical education

Conclusion In this study, it was found that 70% of the students understood the meaning of chemical kinetics, and it helped them analyse the data. The experimental yield of CO₂(g) obtained by the students and the yield calculated were found to match. The exercise is a good example for constructive teaching of several aspects of chemical kinetics.     

Integrator element as a promoter of active learning in engineering teaching

In this paper, we present a teaching proposal used in an Introductory Physics course to civil engineering students from Porto's Engineering Institute/Instituto Superior de Engenharia do Porto (ISEP). The proposal was born from the need to change students’ perception and motivation for learning physics. It consists in the use of an integrator element, called the physics elevator project. This integrator element allows us to use, in a single project, all the content taught in the course and uses several active learning strategies. In this paper, we analyse this project as: (i) a clarifying element of the contents covered in the course; (ii) a promoter element of motivation and active participation in class and finally and (iii) a link between the contents covered in the course and the ‘real world’. The data were collected by a questionnaire and interviews to students. From the data collected, it seems that the integrator element improves students’ motivation towards physics and develops several skills that they consider to be important to their professional future. It also acts as a clarifying element and makes the connection between the physics that is taught and the ‘real world’.

Applying web-based co-regulated learning to develop students' learning and involvement in a blended computing course

This research investigated, via quasi-experiments, the effects of web-based co-regulated learning (CRL) on developing students' computing skills. Two classes of 68 undergraduates in a one-semester course titled “Applied Information Technology: Data Processing” were chosen for this research. The first class (CRL group, n = 38) received the intervention of web-based CRL teaching methods, while the second one (control group, n = 30) received a traditional teaching method for computing education. The results in this study show that students who received the web-based CRL attained significantly better computing skills than those who received the traditional teaching method. This study provides a design and illustration of web-based CRL for teachers, educators, and schools which place importance on improving students' computing skills and pay attention to development of online courses.     

Cooperative learning in a Soil Mechanics course at undergraduate level

The implementation of the Bologna Process enforced a significant change on traditional learning models, which were focused mainly on the transmission of knowledge. The results obtained in a first attempt at implementation of a cooperative learning model in the Soil Mechanics I course of the Department of Civil Engineering of the University of Aveiro, Portugal, are presented and discussed. The students were confronted with situations recreating a professional atmosphere in Geotechnics. Mandatory project team assignments to be prepared in groups were implemented, where each student had to fulfil specific and rotational roles, namely, laboratory/informatics technician, analyst, reporter and coordinator. To assess the implemented model, several strategies were used: students’ feedback; marks monitoring; questionnaires.     

The relationship between student engagement with online content and achievement in a blended learning anatomy course

Blended learning has become increasingly common in higher education. Recent findings suggest that blended learning achieves better student outcomes than traditional face‐to‐face teaching in gross anatomy courses. While face‐to‐face content is perceived as important to learning there is less evidence for the significance of online content in improving student outcomes. Students enrolled in a second‐year anatomy course from the physiotherapy (PT), exercise physiology (EP), and exercise science (ES) programs across two campuses were included (n = 500). A structural equation model was used to evaluate the relationship of prior student ability (represented by grade in prerequisite anatomy course) and final course grade and whether the relationship was mediated by program, campus or engagement with the online elements of the learning management system (LMS; proportion of documents and video segments viewed and number of interactions with discussion forums). PT students obtained higher grades and were more likely to engage with online course materials than EP and ES students. Prerequisite grade made a direct contribution to course final grade (P < 0.001) but was also mediated by engagement with LMS videos and discussion forums (P < 0.001). Student learning outcomes in a blended anatomy course can be predicted the by level of engagement with online content. Anat Sci Educ 11: 471–477. © 2017 American Association of Anatomists.     

The design and implementation of learning paths in a learning management system

Learning paths have the potential to play an important role in the way educators serve their learners. Empirical research about learning paths is scarce, particularly in a secondary education setting. The present quasi-experimental study took place in the context of a biology course involving 360 secondary school students. A 2?×?2 factorial research design was adopted. Learners were engaged in learning activities in a learning path. These learning activities (1) differed in design and (2) were either undertaken individually or collaboratively. Gender was considered as a critical co-variable, given the focus on science learning. All learning paths were developed on the basis of visual representations, but in the experimental design conditions, learners worked with learning paths designed according to Mayer's multimedia guidelines (2003). Multilevel analyses were applied to study the impact on learning outcomes according to the design of learning paths, the individual/collaborative setting, and the co-variable gender. The study provides empirical evidence that both the design and the group setting (collaborative versus individual) have an impact on learning outcomes. Although there was no main effect, several significant interaction effects with gender were found. The results are helpful to direct research about the design and implementation of learning paths in a secondary school setting and underpin the relevance of representation modes in science learning.     

Effects of image‐based and text‐based active learning exercises on student examination performance in a musculoskeletal anatomy course

Research on the benefits of visual learning has relied primarily on lecture‐based pedagogy, but the potential benefits of combining active learning strategies with visual and verbal materials on learning anatomy has not yet been explored. In this study, the differential effects of text‐based and image‐based active learning exercises on examination performance were investigated in a functional anatomy course. Each class session was punctuated with an average of 12 text‐based and image‐based active learning exercises. Participation data from 231 students were compared with their examination performance on 262 questions associated with the in‐class exercises. Students also rated the helpfulness and difficulty of the in‐class exercises on a survey. Participation in the active learning exercises was positively correlated with examination performance (r = 0.63, P < 0.001). When controlling for other key demographics (gender, underrepresented minority status) and prior grade point average, participation in the image‐based exercises was significantly correlated with performance on examination questions associated with image‐based exercises (P < 0.001) and text‐based exercises (P < 0.01), while participation in text‐based exercises was not. Additionally, students reported that the active learning exercises were helpful for seeing images of key ideas (94%) and clarifying key course concepts (80%), and that the image‐based exercises were significantly less demanding, less hard and required less effort than text‐based exercises (P < 0.05). The findings confirm the positive effect of using images and active learning strategies on student learning, and suggest that integrating them may be especially beneficial for learning anatomy.

The effects of passive and active learning on student preference and performance in an undergraduate basic science course

Active learning is based on self-directed and autonomous teaching methods, whereas passive learning is grounded in instructor taught lectures. An animal physiology course was studied over a two-year period (Year 1, n = 42 students; Year 2, n = 30 students) to determine the effects of student-led seminar (andragogical) and lecture (pedagogical) teaching methods on students' retention of information and performance. For each year of the study, the course was divided into two time periods. The first half was dedicated to instructor-led lectures, followed by a control survey in which the students rated the efficiency of pedagogical learning on a five-point Likert scale from one (strongly disagree) to five (strongly agree). During the second period, students engaged in andragogical learning via peer-led seminars. An experimental survey was then administered to students using the same scale as above to determine students' preferred teaching method. Raw examination scores and survey results from both halves of the course were statistically analyzed by ANOVA with Newman-Keuls multiple comparison test. By the end of the study, student preference for peer-led seminars increased [mean ± SD: (2.47 ± 0.94)/(4.03 ± 1.36), P < 0.04], and examination scores significantly increased [mean ± SD: (73.91% ± 13.18)/(85.77 ± 5.22), P < 0.001]. A majority of students (68.8%) preferred a method that contained peer-led seminars and instructor-led lectures. These results may indicate that integration of active and passive learning into undergraduate courses may have greater benefit in terms of student preference and performance than either method alone.
