Constructivism and empiricism: An incomplete divorce

The paper outlines the significant influence of constructivism in contemporary science and mathematics education, and emphasises the central role that epistemology plays in constructivist theory and practice. It is claimed that despite the anti-empiricism of much constructivist writing, in most forms its epistemology is nevertheless firmly empiricist. In particular it is subject-centered and experience-based. It is argued that its relativist, if not skeptical conclusions, only follow given these empiricist assumptions. Further it is suggested that such assumptions belong to Aristotelian science, and were effectively overthrown with the modern science of Galileo and Newton. Thus constructivism cannot provide understanding of post-Aristotelian science. Specializations: history, philosophy and science teaching.

Reducing the length of questionnaires through structurally incomplete designs: An illustration

This paper serves as an illustration of the usefulness of structurally incomplete designs as an approach to reduce the length of educational questionnaires. In structurally incomplete test designs, respondents only fill out a subset of the total item set, while all items are still provided to the whole sample. The scores on the unadministered items are subsequently dealt with by using methods for the estimation of missing data. Two structurally incomplete test designs — one recording two thirds, and the other recording a half of the potentially complete data — were applied to the complete item scores on 8 educational psychology scales. The incomplete item scores were estimated with missing data method Data Augmentation. Complete and estimated test data were compared at the estimates of total scores, reliability, and predictive validity of an external criterion. The reconstructed data yielded estimates that were very close to the values in the complete data. As expected the statistical uncertainty was higher in the design that recorded fewer item scores. It was concluded that the procedure of applying incomplete test designs and subsequently dealing with the missing values is very fruitful for reducing questionnaire length.     

Module Development Through Peer-assisted Student Support: An initial evaluation

The importance of effective module development in terms of content and delivery is becoming increasingly significant within higher education. The majority of evaluation exercises are relatively static and reactive, predominantly utilising standardised evaluation questionnaires. This paper examines the effectiveness of utilising peer-assisted student support, a form of student-centred learning to provide module feedback that cannot be easily identified through traditional methods. Data from meeting logs, observations, interviews and questionnaires demonstrates that student-centred learning feedback can enhance module development, identifying and prompting effective remedial action in shorter timescales. The paper therefore concludes that feedback from student-centred learning initiatives is a viable and dynamic alternative to traditional modes of module development that requires further consideration .     

Infantile Amnesia: Through a Glass Darkly

Memory for former preschool classmates was examined in 9-and 10-year-old children using measures of both explicit and implicit memory. Yes-no recognition of faces was at low levels but was significantly above chance. Skin conductance data showed similarly low but above-chance differentiation between classmates and controls. A median split of children based on their recognition memory scores showed that children with little evidence of explicit memory for classmates were as likely to show differential skin conductance responding to faces of former classmates as were children with higher recognition scores. Infantile amnesia, like the clinical syndrome for which it is named, may not always involve complete loss of encoded information.     

Conceptualizing impact in academic development: finding a way through

This paper explores the notion of impact in the context of academic development programs and considers how it can be described and understood. We argue that impact has a range of meanings and academic development programs such as graduate certificates have a broad group of stakeholders and hence the impact is different for each group depending on how the program aims and objectives are defined and understood. In finding a way through the difficulties of evaluating impact in academic development we point to the importance of clearly conceptualizing the notion of impact, a careful identification of the assumptions underpinning any program and an understanding of who academic development will benefit and how. We suggest that impact in academic development cannot be understood without taking account of the range of possible impacts and the difficulty of attributing simple cause and effect to a complex environment.

Team Hyena Puppet: An Interdisciplinary Approach to Making and Teaching Science Through Art

In 2016, professors representing Biology, Dance, Music, and Theatre and dance program students created Dunes, a performance piece that depicts the ecological succession of Michigan's sand dunes. The process used to make this work is a direct representation of the steps that Team Hyena Puppet, a collective of teaching artists and scientists, takes in their science-based art collaborations, which are used to reflect on and depict scientific research and simultaneously teach student participants and audience members science through the performing arts.     

Canadian Teaching and Learning Centres on Facebook and Twitter: An Exploration Through Social Media

Teaching and Learning Centres (TLCs) play a role in the professional development of faculty, staff and teaching assistants in higher education institutions. One of the functions of many TLCs is that of outreach, not only to the individuals within their institutions who are their primary clientele but also to the greater higher education community. This paper presents an introductory review of Canadian TLCs’ use of social media, seeking to address questions regarding the extent to which Canadian TLCs use social media and the ways in which these are used. Based on frequency of accounts, and on the content of posts in these accounts, the authors found that social media are used by nearly half of all Canadian TLCs to a wide range of purposes. Areas for further inquiry are suggested.     

Democracy Through Learner-Centered Education: a Turkish Perspective

Aimed at documenting the problems and constraints confronting learner-centered instruction in Turkey, this article first explains the link between democracy and education and the role of learner-centered instruction in realizing democratic ends. By drawing on John Dewey’s ideas and Turkish scholars’ perspectives on Turkish education, the article then presents the problems and constraints that pose threats to the implementation of learner-centered instruction in Turkey. The author also explains the problems within the Turkish educational system and teacher education programmes, and the challenges that in-service teachers and students may experience with learner-centered instruction.     

Improving the CBT Development Process Through Knowledge Sharing: An Empirical Study

In this paper, techniques from the research field of knowledge management are used to improve the maturity of the Computer Based Training (CBT) development process at an IT-oriented organization involved in producing courseware. The project team is facilitated with a knowledge-sharing solution that enables them to unambiguously define their project process, and link templates and best practices to the activities in that process. In addition, a virtual discussion room is provided for them to share new insights. Results from measurement experiments indicate more positive project experiences with projects that used the knowledge-sharing solution.

Acute pancreatitis associated left-sided portal hypertension with severe gastrointestinal bleeding treated by transcatheter splenic artery embolization: a case report and literature review

Left-sided portal hypertension (LSPH) followed by acute pancreatitis is a rare condition with most patients being asymptomatic. In cases where gastrointestinal (GI) bleeding is present, however, the condition is more complicated and the mortality is very high because of the difficulty in diagnosing and selecting optimal treatment. A successfully treated case with severe GI bleeding by transcatheter splenic artery embolization is reported in this article. The patient exhibited severe uncontrollable GI bleeding and was confirmed as gastric varices secondary to LSPH by enhanced computed tomography (CT) scan and CT-angiography. After embolization, the bleeding stopped and stabilized for the entire follow-up period without any severe complications. In conclusion, embolization of the splenic artery is a simple, safe, and effective method of controlling gastric variceal bleeding caused by LSPH in acute pancreatitis.     

Secondary-Task Effects on Learning With Multimedia: An Investigation Through Eye-Movement Analysis

This study investigates secondary-task interference on eye movements through learning with multimedia. We focus on the relationship between the influence of the secondary task on the eye movements of learners, and the learning outcomes as measured by retention, matching, and transfer. Half of the participants performed a spatial tapping task while studying the instructional materials, whereas the other half studied the materials, without spatial tapping. The results revealed suboptimal learning outcomes under the secondary task, which was accompanied by fewer transitions of gaze between the text and the figure. We propose that the suboptimal learning outcomes might be due to the disrupted processing of pictures, and possibly due to the less efficient integration, of the information gathered from the text and figures.
