Dutch teachers’ beliefs on linguistic concepts and reflective judgement in grammar teaching

Teacher beliefs have been shown to play a major role in shaping educational practice, especially in the area of grammar teaching―an area of language education that teachers have particularly strong views on. Traditional grammar education is regularly criticized for its focus on rules-of-thumb rather than on insights from modern linguistics, and for its focus on lower order thinking. A growing body of literature on grammar teaching promotes the opposite, arguing for more linguistic conceptual knowledge and reflective or higher order thinking in grammar pedagogy. In the Netherlands, this discussion plays an important role in the national development of a new curriculum. This study explores current Dutch teachers’ beliefs on the use of modern linguistic concepts and reflective judgment in grammar teaching. To this end, we conducted a questionnaire among 110 Dutch language teachers from secondary education and analyzed contemporary school textbooks likely to reflect existing teachers’ beliefs. Results indicate that teachers generally appear to favor stimulating reflective judgement in grammar teaching, although implementing activities aimed at fostering reflective thinking seems to be difficult for two reasons: (1) existing textbooks fail to implement sufficient concepts from modern linguistics, nor do they stimulate reflective thinking; (2) teachers lack sufficient conceptual knowledge from linguistics necessary to adequately address reflective thinking.

Bestuurlijke informatievoorziening met EIS

De bestuurlijke informatievoorziening voor het tactische en strategische management kan tegenwoordig tot stand komen op basis geavanceerde Executive Information Systems (EIS). Maar 'bestuurlijke informatievoorziening met EIS' vraagt om essentiele basiskennis omtrent besturen en bestuurlijke informatie binnen organisaties. In dit artikel staan met name de toepassing van de tools centraal.

Management of LBP at primary care level in South Africa: up to standards?

BACKGROUND: Primary Health Care (PHC) is well suited for management of low back pain (LBP). Prevalence of (chronic) LBP is suspected to be high among visitors of the South African primary care centers, but currently no information exists on prevalence or guideline adherence.OBJECTIVES: To establish if treatment received for LBP in public PHC in the Cape Town area compares with international evidence based guidelines.METHODS: Cluster randomization determined the 8 community health centres where the study took place. A measurement tool was developed and validated for this population. Descriptive analysis and logistic regression analytical techniques were applied.RESULTS: 489 participants (mean age: 44.8) were included in this study. Lifetime prevalence was 73.2% and 26.3% suffered from chronic low back pain (CLBP) . Pain medication was the only form of treatment received by 90% of the sample. Interventions received seemed to be unrelated to type of LBP (acute, sub acute and chronic). Referral to physiotherapy, education and advice to stay active were rarely done. Participants expressed low satisfaction with treatment.CONCLUSIONS: Current management of LBP at PHC level appears to be ineffective and not conform guidelines. Further South African research should focus on barriers as well as measures to be taken for implementation of LBP guidelines.

Switching Power Supplies in DC Grids

The Smart Current Limiter is a switching DC to DC converter that provides a digitally pre-set input current control for inrush limiting and power management. Being able to digitally adjust the current level in combination with external feedback can be used for control systems like temperature control in high power DC appliances. Traditionally inrush current limiting is done using a passive resistance whose resistance changes depending on the current level. Bypassing this inrush limiting resister with a Mosfet improves efficiency and controllability, but footprint and losses remain large. A switched current mode controlled inrush limiter can limit inrush currents and even control the amount of current passing to the application. This enables power management and inrush current limitation in a single device. To reduce footprint and costs a balance between losses and cost-price on one side and electromagnetic interference on the other side is sought and an optimum switching frequency is chosen. To reduce cost and copper usage, switching happens on a high frequency of 300kHz. This increases the switching losses but greatly reduces the inductor size and cost compared to switching supplies running on lower frequencies. Additional filter circuits like snubbers are necessary to keep the control signals and therefore the output current stable.

Verbinding als sleutel tot binnenstedelijke kwaliteit

Deze publicatie bevat de belangrijkste bevindingen van een verkenning van de kansen die de inzet van retail en cultuur bieden voor de ontwikkeling van kwaliteit in binnensteden. Een groot aantal gemeenten wordt geconfronteerd met vraagstukken over de herinrichting van zowel hun kernen als de omliggende wijken en gebieden. Tegelijkertijd geldt dat zowel retail als cultuur zich voor belangrijke uitdagingen gesteld zien in het postcorona tijdperk. In ‘Verbinding als sleutel tot stedelijke kwaliteit’ wordt de problematiek uiteengezet, de kansen en mogelijkheden van een ontwerpbenadering toegelicht en een tweetal cases behandeld: Hart van Zuid in Rotterdam en Osdorpplein in Amsterdam.
