Integrated STEM in secondary education: A case study

Despite many opportunities to study STEM (Science, Technology, Engineering & Mathematics) in Flemish secondary education, only a minority of pupils are actually pursuing STEM fields in higher education and jobs. One reason could be that they do not see the relevance of science and mathematics. In order to draw their pupils’ interest in STEM, a Belgian school started a brand new initiative: the school set up and implemented a first year course that integrates various STEM disciplines, hoping to provide an answer to the question pupils often ask themselves about the need to study math and science. The integrated curriculum was developed by the school’s teachers and a STEM education research group of the University of Leuven. To examine the pupils’ attitude towards STEM and STEM professions and their notion of relevance of STEM at the end of this one-year course, a post-test was administered to the group of pupils who attended the integrated STEM course (the experimental group) and to a group of pupils that took traditional, non-integrated STEM courses (the control group). The results reveal that attending the integrated STEM course is significantly related to pupils’ interest in STEM and notion of relevance of STEM. Another post-test was administered only to the experimental group to investigate pupils’ understanding of math and physics concepts and their relation when taught in an integrated way. The results reveal that the pupils have some conceptual understanding and can, to a certain extent, make a transfer of concepts across different STEM disciplines. However, the test results did point out that some additional introductory training in pure math context is needed

The effect of the eHealth intervention ‘MyPlan 1.0’ on physical activity in adults who visit general practice : a quasi-experimental trial

Physical inactivity is one of the major risk factors for poor health in the world. Therefore, effective interventions that promote physical activity are needed. Hence, we developed an eHealth intervention for adults, i.e., ‘MyPlan 1.0’, which includes self-regulation techniques for behaviour change. This study examined the effect of ‘MyPlan 1.0’ on physical activity (PA) levels in general practice. 615 adults (≥18 years) were recruited in 19 Flemish general practices, for the intervention group (n = 328) or for the wait-list control group (n = 183). Participants in the intervention group received the web-based intervention ‘MyPlan 1.0’ and were prompted to discuss their personal advice/action plan with their general practitioner. Participants in the wait-list control group only received general advice from the website. Self-reported physical activity was assessed with the International Physical Activity Questionnaire (IPAQ) at baseline and after one month. A three-level (general practice, adults, time) regression analysis was conducted in MLwiN. Significant intervention effects were found for total PA and moderate to vigorous PA with an increase for the intervention group compared to a decrease in the control condition. However, there was a high dropout rate in the intervention group (76%) and the wait-list control group (57%). Our self-regulation intervention was effective in increasing physical activity levels in adults. Future studies should consider strategies to prevent the large dropout from participants

A genome-wide search for epigenetically regulated genes in zebra finch using MethylCap-seq and RNA-seq

Learning and memory formation are known to require dynamic CpG (de)methylation and gene expression changes. Here, we aimed at establishing a genome-wide DNA methylation map of the zebra finch genome, a model organism in neuroscience, as well as identifying putatively epigenetically regulated genes. RNA-and MethylCap-seq experiments were performed on two zebra finch cell lines in presence or absence of 5-aza-2'-deoxycytidine induced demethylation. First, the MethylCap-seq methodology was validated in zebra finch by comparison with RRBS-generated data. To assess the influence of (variable) methylation on gene expression, RNA-seq experiments were performed as well. Comparison of RNA-seq and MethylCap-seq results showed that at least 357 of the 3,457 AZA-upregulated genes are putatively regulated by methylation in the promoter region, for which a pathway analysis showed remarkable enrichment for neurological networks. A subset of genes was validated using Exon Arrays, quantitative RT-PCR and CpG pyrosequencing on bisulfite-treated samples. To our knowledge, this study provides the first genome-wide DNA methylation map of the zebra finch genome as well as a comprehensive set of genes of which transcription is under putative methylation control

Een exploratieve studie naar de relatie tussen geïntegreerd STEM-onderwijs en STEM-attitude op secundair niveau

Hoewel de groeiende economie nood heeft aan ingenieurs, technici en wetenschappers, m.a.w. mensen met een STEM-profiel (STEM = Science, Technology, Engineering & Mathematics), verlaten slechts 43% van de leerlingen in Vlaanderen het secundair onderwijs en 19% van de studenten het hoger onderwijs met een STEM-diploma. Bovendien kiezen de STEM-gediplomeerden niet noodzakelijk voor een STEM-beroep. In het masterplan voor de hervormingen van het secundair onderwijs in Vlaanderen wordt daarom ook het belang van techniek en wetenschap in het curriculum benadrukt. Wetenschaps- en techniekonderwijs vergen echter niet alleen meer aandacht in het curriculum, maar ook een geïntegreerd aanbod van de verschillende STEM-componenten in het wetenschaps- en techniekonderwijs is belangrijk. Volgens de literatuur maakt geïntegreerd STEM-onderwijs leerlingen bewuster van de relevantie van wetenschappen en wiskunde voor hun eigen leefwereld of voor de maatschappij, wat zou kunnen leiden tot een positievere houding ten opzichte van STEM (cf. Breiner et al., 2012; Sjøberg & Schreiner, 2010). In deze paper gaan we na in welke mate leerlingen die geïntegreerd STEM-onderwijs hebben gevolgd verschillen in hun houding ten opzichte van STEM van leerlingen die geen geïntegreerd STEM-onderwijs hebben gevolgd.status: publishe

Een nieuwe didactiek, richting abstract geïntegreerd STEM-onderwijs

Aan het begin van dit artikel wordt de aanleiding besproken: de te lage uitstroom uit STEM-richtingen in het Secundair Onderwijs. De resultaten van de ROSE-studie, die in het tweede deel besproken worden, reiken hiervoor een duidelijke reden aan: het feit dat jongeren de relevantie van wetenschappen en wiskunde niet inzien. In het derde deel wordt onze visie op de didactiek van geïntegreerd STEM-onderwijs uit de doeken gedaan aan de hand van de verschillende principes waarop ze stoelt. Om de ontwikkeling en uitrol van deze nieuwe didactiek, zoals ze voorgesteld wordt in dit artikel, te ondersteunen en te valideren, is het project ‘STEM@school’ opgezet door verschillende partners. Het artikel sluit af met de objectieven, het samenwerkingsconcept, de invulling en de planning op langere termijn van dit nieuwe project in het kader van Strategisch Basisonderzoek (SBO).status: publishe

Measuring and Activating iSTEM Key Principles among Student Teachers in STEM

Graduates with a STEM profile are in great demand, yet the outflow from these fields of study is highly insufficient. This is partly due to the fragmented way STEM learning content is taught in secondary education. Although the problem can be mitigated with the use of integrated STEM education (i.e., iSTEM), teachers are often unfamiliar with this type of education. To support teachers in implementing high-quality iSTEM education, a digital collaborative learning environment called “CODEM for iSTEM” was created. This study examined to what extent student teachers were immersed in six key principles of iSTEM education through cooperative design of iSTEM learning tools in multidisciplinary teams, namely “problem-centered learning”, “integration of different STEM disciplines”, “modeling”, “inquiry-based learning”, “design-based learning”, and “cooperative learning”
