This study explores the spontaneous explanatory models children construct, critique, and revise in the context of tasks in which children need to predict, observe, and explain phenomena involving magnetism. It further investigates what conceptual resources students use, and in what ways they use them, to construct explanatory models, and the…

As biotechnology-related scientific advances, such as stem cell research (SCR), are increasingly permeating the popular media, it has become ever more important to understand students' ideas about this issue. Very few studies have investigated learners' ideas about biotechnology. Our study was designed to understand the types of alternative…

Whilst sex is considered to be one of the most significant factors influencing attitudes towards science, previous research seems to suggest that, at least in non-science classes, there is no correlation between sex and motivation to learn science. The present study investigates a mixed group of science and non-science students of upper secondary…

We have analysed the processes of argumentation of three university student groups (A: six students, C: five students, and J: seven students) while making a decision about an environmental problem (selection of a heating system). The discussions took place in three 1 1/2-hour sessions that were audio-taped and transcribed. For the analysis of the…

How do external visual representations (e.g., graph, diagram) promote or constrain students' ability to identify system components and their interrelations, to reinforce a systemic view through the application of the STS approach? University students (N = 150) received information cards describing cellphones' communication system and its subsystem…

This study proposes a multi-dimensional approach to investigate, represent, and categorize students' in-depth understanding of complex physics concepts. Clinical interviews were conducted with 30 undergraduate physics students to probe their understanding of heat conduction. Based on the data analysis, six aspects of the participants' responses…

The study examines the nature, conditions, and outcomes of student learning from an organised guided tour in the Deutsches Museum in Munich. The instructional methods that best support students' cognitive and affective learning as well as how students' motivational and emotional states influence their achievement were investigated. A sample of 96…

The mini-CEX is widely used to rate directly observed resident-patient encounters. Although several studies have explored the reliability of mini-CEX scores, the dimensionality of mini-CEX scores is incompletely understood. Objective: Explore the dimensionality of mini-CEX scores through factor analysis and generalizability analysis. Design:…

Problem based learning (PBL) is often introduced in curricula in form of short segments. In the literature the value of these PBL-islands is doubted. In order to gain more insight in this curricular approach, we compared student generated learning issues, from a 7-week PBL-island introduced in a traditional curriculum (PBL-I), with the gold…

Reviewers of research reports frequently criticize the choice of statistical methods. While some of these criticisms are well-founded, frequently the use of various parametric methods such as analysis of variance, regression, correlation are faulted because: (a) the sample size is too small, (b) the data may not be normally distributed, or (c) The…

It has become axiomatic that assessment impacts powerfully on student learning, but there is a surprising dearth of research on how. This study explored the mechanism of impact of summative assessment on the process of learning of theory in higher education. Individual, in-depth interviews were conducted with medical students and analyzed…

Effective mentoring has an invaluable role in the development of surgeons at various levels and is frequently perceived vital in achieving career success. Its role therefore is only second to credentialing. However, the formal role of mentoring and learner support in surgical training remains non-existent. This is reflected in a paucity of…

Authors have claimed that Internet-based instruction promotes greater learning efficiency than non-computer methods. Objectives Determine, through a systematic synthesis of evidence in health professions education, how Internet-based instruction compares with non-computer instruction in time spent learning, and what features of Internet-based…

During in-training assessment students are frequently assessed over a longer period of time and therefore it can be expected that their performance will improve. We studied whether there really is a measurable performance improvement when students are assessed over an extended period of time and how this improvement affects the reliability of the…

Teaching clinic managers struggle to convert performance data into meaningful behavioral change in their trainees, and quality improvement measures in medicine have had modest results. This may be due to several factors including clinical performance being based more on team function than individual action, models of best practice that are…
