In this article, we report on a study that investigated the motivational (e.g. intrinsic motivation) and dispositional variables (e.g. attitudes) that determine teachers’ intention to use or not to use digital learning materials (DLMs). To understand the direct and indirect relationships between these variables, we replicated a study in which self-determination theory (SDT) and the theory of planned behaviour/integrated model of behaviour prediction (IMBP) are combined and a distinction was made between global level psychological needs, and contextual level as well as situational level motivational constructs. Using a sample of 1273 teachers, our preliminary findings support the findings of the previous study. The combined model potentially provides us with a more comprehensive explanation of teachers’ volitional behaviour regarding their use of DLMs in their pedagogical practices than would be possible on the basis of SDT or IMBP alone. 相似文献

This study investigated the effects of feedback providing improvement strategies and a reflection assignment on students’ writing motivation, process, and performance. Students in the experimental feedback condition (n = 41) received feedback including improvement strategies, whereas students in the control feedback condition (n = 41) received feedback without improvement strategies. Within each feedback condition, half of the students received a reflection assignment on feedback use and the revision (experimental reflection condition), while the other half received a reflection assignment on feedback perception (control reflection condition). Results indicated that in the experimental feedback condition writing performance gained from the control reflection assignment, while in the control feedback condition it gained from the experimental reflection assignment. Improvement strategies negatively predicted self-efficacy beliefs, especially when initial self-efficacy beliefs were low, and positively predicted planning/revising. Reflections on feedback use and the revision positively predicted mastery goal when mastery goal initially was low or moderate. 相似文献

After graduation, it is essential for teachers to continue working on their professional development since they need to be prepared for the requirements of tomorrow's knowledge- and technology-based society, a more varied student and pupil population creating new responsibilities, and higher social expectations from schools and the society as a whole. Although attention for teachers’ professional development at work is increasing, the availability of valid survey instruments that measure their participation in professional development at work is still limited. Based on a literature review, such an instrument was designed. This 21-item self-report measure, using a 4-point rating scale, makes an inventory of teachers’ participation in activities contributing to professional development. The purpose of the instrument is to make teachers, school leaders and other stakeholders aware of whether, and to what degree, teachers engage in learning at work. This is important because ultimately the quality of education depends on it. A survey was administered in 9 Dutch primary schools and 15 Dutch secondary schools. Exploratory and Confirmatory Factor Analysis confirmed a six-factor structure, and augments earlier findings in the field. The reliabilities of the six subscales were sufficient to good. 相似文献

ABSTRACTResearch on the use of Massive Open Online Courses (MOOCs) for teacher professional development (TPD) and the characteristics of their participants is scarce. This article presents a case of a MOOC initiative supported by the Spanish Ministry of Education aiming at teachers’ professional development on the use of ICT for teaching and learning. The analysis is focused on (a) the sociodemographic and school characteristics of the teachers participating in MOOCs; (b) their experience and beliefs about lifelong learning; and (c) the relevance of MOOCs for their work. By contrasting the characteristics of the participants in this initiative with the characteristics of the whole population of teachers in Spain, and a sample of Spanish participants in MOOCs not aimed at TPD, the article sheds light on the specificities of the teachers who use this way of TPD. The results have implications for the design of programmes aimed to develop MOOCs for TPD. 相似文献

Why teachers use digital learning materials: The role of self-efficacy, subjective norm and attitude
Frederik Van Acker Hans van Buuren Karel Kreijns Marjan Vermeulen 《Education and Information Technologies》2013,18(3):495-514
Although Information and Communication Technology (ICT) seems a promising tool in an educational context, many teachers are reluctant to integrate it in their daily practice. A large scale survey was undertaken amongst primary and secondary school teachers in the Netherlands to explore possible determinants of the educational use of digital learning materials (DLMs) in order to develop interventions to reduce teachers’ reluctance to use ICT and more specifically to stimulate the use of DLMs. Basing on the Integrative Model of Behaviour Prediction it was conjectured that self-efficacy, attitude and subjective norm would take a central role in explaining the intention to use DLMs. Several other predictors were added to the conceptual model whose effects were hypothesized to be mediated by the three central variables. All conjectured relationships were found using mediation analysis on survey data from 1,484 teachers. Intention to use DLMs was most strongly determined by attitude, followed by self-efficacy. ICT skills was in its turn the strongest predictor of self-efficacy. Subjective norm played only a limited role in the intention to use DLMs. Basing on the outcome of this study, persuasive communication focusing on positive outcomes and skills based training seem appropriate interventions to promote a positive attitude towards DLM and improve self-efficacy in using DLMs. 相似文献

Introduction
Although prostatitis is a common male urinary tract infection, clinical diagnosis of prostatitis is difficult. The developmental mechanism of prostatitis is not yet unraveled which led to the elaboration of various biomarkers. As changes in asparagine-linked-(N-)-glycosylation were observed between healthy volunteers (HV), patients with benign prostate hyperplasia and prostate cancer patients, a difference could exist in biochemical parameters and urinary N-glycosylation between HV and prostatitis patients. We therefore investigated if prostatic protein glycosylation could improve the diagnosis of prostatitis.Materials and methods
Differences in serum and urine biochemical markers and in total urine N-glycosylation profile of prostatic proteins were determined between HV (N = 66) and prostatitis patients (N = 36). Additionally, diagnostic accuracy of significant biochemical markers and changes in N-glycosylation was assessed.Results
Urinary white blood cell (WBC) count enabled discrimination of HV from prostatitis patients (P < 0.001). Urinary bacteria count allowed for discriminating prostatitis patients from HV (P < 0.001). Total amount of biantennary structures (urinary 2A/MA marker) was significantly lower in prostatitis patients compared to HV (P < 0.001). Combining the urinary 2A/MA marker and urinary WBC count resulted in an AUC of 0.79, 95% confidence interval (CI) = (0.70–0.89) which was significantly better than urinary WBC count (AUC = 0.70, 95% CI = [0.59–0.82], P = 0.042) as isolated test.Conclusions
We have demonstrated the diagnostic value of urinary N-glycosylation profiling, which shows great potential as biomarker for prostatitis. Further research is required to unravel the developmental course of prostatic inflammation.Key words: diagnostic marker, prostatitis, urinary asparagine-linked glycosylation 相似文献20.
