We conducted a descriptive study among first-year engineering students at the Anton de Kom University of Suriname. We analyzed students’ errors regarding necessary prior knowledge in a calculus A exam. We found that the stage of the solution in which prior knowledge is required impacts the importance of prior knowledge. We also found that many errors concerned basic algebra and trigonometry concepts and skills. We concluded that even though the required prior knowledge concerns basic algebra and trigonometry, the stage of the solution in which prior knowledge is needed is of great importance.

© 2014 Springer Science+Business Media New York Video is increasingly used as an instructional tool. It is therefore becoming more important to improve learning of students from video. We investigated whether student learning effects are influenced through an instruction about other viewing behaviours, and whether these learning effects depend on their prior knowledge. In a controlled environment, 115 students watched a number of instructional videos about the technical equipment needed in a course on digital photography. Every second student was instructed about other possible viewing behaviours. A pre-post-retention test was carried out to calculate learning effects. The differences with respect to the learning effects of students who received an awareness instruction on an alternative viewing strategy were not significantly different. The differences as observed in our earlier experiment however could not be reproduced. Students with a broad viewing repertoire showed higher learning effects than students with a narrow repertoire. Furthermore, students with a strategic viewing approach also showed higher learning effects. Certain conditions have to be met: the technical and didactical quality of the video must be good, the integration in a learning task must be apparent, students must be aware of their viewing behaviour, and teachers must be aware of their students’ viewing behaviour in order to enrich the viewing repertoire of students when they have at least some basic knowledge e.g. after several lessons on the topics at hand. In future research, this study should be replicated using more complex video episodes than the instruction videos we used in our experiments that were only on the factual knowledge level of the taxonomy of Bloom. Moreover, replication of this study with a larger sample size could yield a significant improvement in learning effects. This is plausible because students need an amount of prior knowledge beyond a certain threshold value in order to be able to expand their knowledge network in their long term memory. Finally, additional media player functionality, facilitating effective student learning from video, can be described based on the results of this study.

A case study and method development research of online simulation gaming to enhance youth care knowlegde exchange. Youth care professionals affirm that the application used has enough relevance as an additional tool for knowledge construction about complex cases. They state that the usability of the application is suitable, however some remarks are given to adapt the virtual environment to the special needs of youth care knowledge exchange. The method of online simulation gaming appears to be useful to improve network competences and to explore the hidden professional capacities of the participant as to the construction of situational cognition, discourse participation and the accountability of intervention choices.

BACKGROUND: Malnutrition is an important risk factor for adverse post-operative outcomes. The prevalence of risk for malnutrition is unknown in patients prior to vascular surgery. We aimed to assess prevalence and associated factors of risk for malnutrition in this patient group.METHODS: Patients were assessed for risk for malnutrition by the Patient-Generated Subjective Global Assessment Short Form. Demographics and medical history were retrieved from the hospital registry. Uni- and multivariate analyses were performed to identify associated factors of risk for malnutrition.RESULTS: Of 236 patients, 57 (24%) were categorized as medium/high risk for malnutrition. In the multivariate analyses, current smoking (P = 0.032), female sex (P = 0.031), and being scheduled for amputation (P = 0.001) were significantly associated with medium/high risk for malnutrition.CONCLUSIONS: A substantial proportion (24%) of patients prior to vascular surgery is at risk for malnutrition, specifically smokers, females and patients awaiting amputation. Knowledge of these associated factors may help to appoint patients for screening.

The focus of the thesis is an exploration into students’ vocational knowledge in the context of Dutch vocational education and training (VET). The reason students’ vocational knowledge requires exploration is because there is no consensus among scholars in the field of VET about how to theorise the nature of students’ vocational knowledge; most (not all) scholars rely on dichotomous conceptualisations, such as theory versus practice, general versus specific or explicit versus implicit. However, such commonly used dichotomies are not very helpful to understand the complex nature of vocational knowledge. Vocational knowledge is more than putting bits of theoretical and practical knowledge together, it is characterised by sometimes-intimate relationships between knowledge and actions. As a result of the above-mentioned gap in the VET literature, there is little empirical research on how VET students develop vocational knowledge and the extent to which this is occupation-specific knowledge. To understand students’ vocational knowledge, four different aims are formulated and carried out in four studies. The aim of the first study is to identify powerful vocational learning environments to enable the selection of a case that represents high quality vocational learning and teaching. With an eye on analysing students’ vocational knowledge, the second study aims to conceptualise the nature of vocational knowledge that avoids dichotomies. Therefore, two conceptual frameworks are integrated; the idea of contextualising is introduced which is based on cultural-historical theory to highlight the crucial role activity plays in knowledge development and to understand the relationships between the mind (i.e., what people think (and feel)), and action (i.e., what people do). Secondly, the theory is supplemented with ideas from inferentialism, a philosophical semantic theory of meaning to provide a useful way to focus on students’ processes of knowing and to reveal students’ vocational knowledge in terms of ongoing reasoning processes. The third study uses the conceptualisation of vocational knowledge to explore how students develop vocational knowledge in occupational practice, and to illustrate the process of contextualising. The forth study aims to describe what characterises students’ vocational knowledge using an analytic framework that distinguishes between occupation-specific knowledge components and qualities. This thesis contributes to research scholarship in the field of VET and an understanding of students’ vocational knowledge in practice. The theoretical framework of contextualising supplemented with inferentialism provides an alternative way to focus on students’ processes of knowing and helps to reveal students’ vocational knowledge in terms of reasoning processes. The empirical explorations and illustrations of students’ vocational knowledge contribute to the scholarly literature and practice on understanding the nature of vocational knowledge, how students develop vocational knowledge and what characterises their vocational knowledge. The intention to introduce the idea of contextualising is not about reinventing the wheel but rather an attempt to understand how it turns and how it functions. The intention of this thesis is to encourage dialogue and move the debate about the nature of vocational knowledge further, and hence, to provide some “food for thought”.

PCK is seen as the transformation of content knowledge and pedagogical knowledge into a different type of knowledge that is used to develop and carry out teaching strategies. To gain more insight into the extent to which PCK is content specific, the PCK about more topics or concepts should be compared. However, researchers have rarely compared teachers’ concrete PCK about more than one topic. To examine the content dependency of PCK, we captured the PCK of sixteen experienced Dutch history teachers about two historical contexts (i.e. topics) using interviews and Content Representation questionnaires. Analysis reveals that all history teachers’ PCK about the two contexts overlaps, although the degree of overlap differs. Teachers with relatively more overlap are driven by their overarching subject related goals and less by the historical context they teach. We discuss the significance of these outcomes for the role of teaching orientation as a part of PCK.

The importance of PCK to quality teaching is widely recognized. However, an overview of research about geography teachers’ PCK is missing. To fill this gap, we conducted a systematic review. We analyzed 43 empirical studies, but only 9 used PCK as a framework. Most studies addressed instructional strategies or teaching orientations. The studies were too diverse to draw conclusions on geography teachers’ PCK in general. But portraits of 16 geography teachers emphasized the necessity of geographical knowledge and teaching experience for PCK-quality.

In general, people are poorly protected against cyberthreats, with the main reason being user behaviour. For the study described in this paper, a ques-tionnaire was developed in order to understand how people’s knowledge of and attitude towards both cyberthreats and cyber security controls affect in-tention to adopt cybersecure behaviour. The study divides attitude into a cog-nitive and an affective component. Although only the cognitive component of attitude is usually studied, the results from a questionnaire of 300 respond-ents show that both the affective and cognitive components of attitude have a clearly positive, albeit varying, influence on behavioural intention, with the affective component having an even greater effect on attitude than the cog-nitive aspect. No correlation was found between knowledge and behavioural intention. The results indicate that attitude is an important factor to include when developing behavioural interventions, but also that different kinds of attitude should be addressed differently in interventions.

Orthography is considered to be a major problem in Dutch education, since many pupils don’t seem to be able to master orthographic rules, even after years of education. In educational literature it is argued that the problems related to spelling are caused by approaches that focus more on rules of thumb than on linguistic insights. This is somewhat remarkable, since a good understanding of the Dutch orthographic system requires a fair amount of morphological knowledge. In order to effectively implement this knowledge, the development of a morphological awareness (MA) seems to be required. Therefore, a short intervention was designed for the upper levels of secondary schools (4 havo) which aimed to foster MA and, subsequently, improve orthographic skills. Results of this quasi-experimental study indicate that a short intervention can significantly boost MA, but that students don’t seem to be able to use MA effectively to enhance spelling performance.

BACKGROUND AND OBJECTIVE: High-velocity low-amplitude thrust spinal manipulation (SM) is a recommended and commonly used manual therapy intervention in physiotherapy. Beliefs surrounding the safety and effectiveness of SM have challenged its use, and even advocated for its abandonment. Our study aimed to investigate the knowledge and beliefs surrounding SM by Italian physiotherapists compared with similar practitioners in other countries.METHODS: An online survey with 41 questions was adapted from previous surveys and was distributed via a mailing list of the Italian Physiotherapists Association (March 22-26, 2020). The questionnaire was divided into 4 sections to capture information on participant demographics, utilization, potential barriers, and knowledge about SM. Questions were differentiated between spinal regions. Attitudes towards different spinal regions, attributes associated with beliefs, and the influence of previous educational background were each evaluated.RESULTS: Of the 7398 registered physiotherapists, 575 (7.8%) completed the survey and were included for analysis. The majority of respondents perceived SM as safe and effective when applied to the thoracic (74.1%) and lumbar (72.2%) spines; whereas, a smaller proportion viewed SM to the upper cervical spine (56.8%) as safe and effective. Respondents reported they were less likely to provide and feel comfortable with upper cervical SM (respectively, 27.5% and 48.5%) compared to the thoracic (respectively, 52.2% and 74.8%) and lumbar spines (respectively, 46.3% and 74.3%). Most physiotherapists (70.4%) agreed they would perform additional screening prior to upper cervical SM compared to other spinal regions. Respondents who were aware of clinical prediction rules were more likely to report being comfortable with SM (OR 2.38-3.69) and to perceive it as safe (OR 1.75-3.12). Finally, physiotherapists without musculoskeletal specialization, especially those with a traditional manual therapy background, were more likely to perform additional screening prior to SM, use SM less frequently, report being less comfortable performing SM, and report upper cervical SM as less safe (p < 0.001).DISCUSSION: The beliefs and attitudes of physiotherapists surrounding the use of SM are significantly different when comparing the upper cervical spine to other spinal regions. An educational background in traditional manual therapy significantly influences beliefs and attitudes. We propose an updated framework on evidence-based SM.
