The relation between prior knowledge and students' collaborative discovery learning processes
In this study we investigate how prior knowledge influences knowledge development during collaborative discovery learning. Fifteen dyads of students (pre-university education, 15-16 years old) worked on a discovery learning task in the physics field of kinematics. The (face-to-face) communication between students was recorded and the interaction with the environment was logged. Based on students' individual judgments of the truth-value and testability of a series of domain-specific propositions, a detailed description of the knowledge configuration for each dyad was created before they entered the learning environment. Qualitative analyses of two dialogues illustrated that prior knowledge influences the discovery learning processes, and knowledge development in a pair of students. Assessments of student and dyad definitional (domain-specific) knowledge, generic (mathematical and graph) knowledge, and generic (discovery) skills were related to the students' dialogue in different discovery learning processes. Results show that a high level of definitional prior knowledge is positively related to the proportion of communication regarding the interpretation of results. Heterogeneity with respect to generic prior knowledge was positively related to the number of utterances made in the discovery process categories hypotheses generation and experimentation. Results of the qualitative analyses indicated that collaboration between extremely heterogeneous dyads is difficult when the high achiever is not willing to scaffold information and work in the low achiever's zone of proximal development
Cognitive Structures of Good and Poor Novice Problem Solvers in Physics
The way knowledge is organized in memory is generally expected to relate to the degree of success in problem solving. In the present study, we investigated whether good novice problem solvers have their knowledge arranged around problem types to a greater extent than poor problem solvers have. In the subject of physics (electricity and magnetism), 12 problem types were distinguished according to their underlying physics principles. For each problem type, a set of elements of knowledge containing characteristics of the problem situation, declarative knowledge, and procedural knowledge was constructed. All of the resulting 65 elements were printed on cards, and first-year university students in physics ( N = 47) were asked to sort these cards into coherent piles shortly after they had taken an examination on electricity and magnetism. Essentially, good novice problem solvers sorted the cards according to problem types; the sorting by the poor problem solvers seemed to be determined to a greater extent by the surface characteristics of the elements. We concluded than an organization of knowledge around problem types might be highly conducive to good performance in problem solving by novice problem solvers

Poistions takens vary from a preference for direct, expository, teacher-led instruction (Kirschner, Sweller, & Clark, 2006) to fully open student-centered approaches that can be called pure discovery methods (e.g., Papert, 1980), with intermediate positions represented by more or less guided discovery methods (e.g., Mayer, 2004). This discussion also is a recurring theme in this chapter."

The effects of screen captures in manuals: A textual and two visual manuals compared.
The study examines the use of screen captures in manuals. Three designs of manuals were compared, one textual and two visual manuals. The two visual manuals differed in the type of screen capture that was used. One had screen captures that showed only the relevant part of the screen, whereas the other consisted of captures of the full screen. All manuals contained exactly the same textual information. We examined the time used on carrying out procedures (manual used as a job aid) and the results on retention tests (manual used for learning). We expected to find a trade-off between gain in time and learning effects. That is, we expected that higher scores on the retention tests involved an increase in time used and, vice versa, that gains in time would lead to lower retention test scores. We also explored the influence of manual design on user motivation. For job-aid purposes, there were no differences between manuals. For learning, the full-screen captures manual and the textual manual were significantly better than the partial-screen captures manual. There was no proof for the expected trade-off. More learning was not caused by an increase in time used. We found no effects on user motivation. This study does not yield convincing evidence to support the presence of screen captures in manuals. However, if one wants to include screen captures, this study gives clarity for the type of screen capture to choose. The use of full-screen captures is preferable to partial ones. Finally, we conclude that documentation designed to expedite the execution of tasks does not necessarily hamper the learning that may resul
"Do screen captures in manuals make a difference?": a comparison between textual and visual manuals
Examines the use of screen captures in manuals. Three types of manuals were compared: one textual and two visual. The two visual manuals differed in the type of screen capture that was used. One had screen captures that showed only the relevant part of the screen, whereas the other consisted of captures of the full screen. All manuals contained exactly the same textual information. We examined immediate use on time (use as a job aid) and on learning (use as a teacher). For job-aid purposes, there was no difference between the manuals. The visual manual with full-screen captures and the textual manual were both better for learning than the visual manual with partial screen captures. We found no effect on user motivation. The tentative conclusion of this study is that screen captures seem not to be vital for learning or immediate use. If one opts for including screen captures, then the conclusion is that full-screen captures are better than partial one
Effects of planning on task load, knowledge, and tool preference:A comparison of two tools
Self-regulated learners are expected to plan their own learning. Because planning is a complex task, it is not self-evident that all learners can perform this task successfully. In this study, we examined the effects of two planning support tools on the quality of created plans, planning behavior, task load, and acquired knowledge. Sixty-five participants each worked with two versions of a planning tool. In one version, learning plans were actively constructed by the learners themselves; the other version provided learners with an adaptable computer-generated plan. The results indicated that the quality of learner-created plans was lower than computer-generated plans. Furthermore, participants reported a higher task load when they constructed the plans by themselves. However, participants gained more structural knowledge about the learning domain when they actively created plans. There was not an apparent preference for one of the tools if participants were to create a plan for someone else. However, if they were to use the plan for their own learning, participants preferred to actively create their own plans
Opleiding bedrijfseconomie:Integratie van duurzaamheid in de opleiding tot bedrijfsecononoom
Hoe integreer je Maatschappelijk Verantwoord Ondernemen (MVO) in het vakgebied van de bedrijfseconoom en wat betekent dit voor de opleiding? Dit is een centrale vraag van het lectoraat Duurzaam Financieel Management – de kenniswerkplaats van de Hanzehogeschool Groningen. In de afgelopen jaren heeft het lectoraat kennis verworven over de mogelijkheden om MVO en het beroep van de controller met elkaar te verbinden. Deze kennis wordt hierbij gedeeld om als basis te dienen voor verdere ontwikkeling
The ZAP project:designing interactive computer tools for learning psychology
In the ZAP project, a set of interactive computer programs called 'ZAPs' was developed. The programs were designed in such a way that first-year students experience psychological phenomena in a vivid and self-explanatory way. Students can either take the role of participant in a psychological experiment, they can experience phenomena themselves, or they can take the role of researcher and learn by discovery. ZAPs provide added value to existing learning materials about psychological topics and can elicit experiential and discovery learning activities. This article discusses the practical and theoretical considerations that underlie the design and structure of ZAPs and provides guidelines for their practical application in different educational settings.
