This study focuses on the development of the understanding of historical time of pupils in primary school. We present a developmental model with three stages: emergent, initial and continued understanding of historical time. Based on this model, we constructed an instrument to measure how pupils aged 6–12 perform. The participants were 1457 pupils from 7 Dutch primary schools. The analysis of the data showed that in all three stages pupils in higher grades significantly outperformed pupils in lower grades and that pupils’ performances were influenced by the variables gender and parents’ education. In all grades, there seemed to be room for improvement, especially in the lower grades (ages 6–9) where pupils have hardly had any teaching on the understanding of historical time. However, in the higher grades as well (ages 10–12), pupils could improve on the level of continued understanding of historical time. 相似文献

This paper describes the development and evaluation of a course in physiotherapy whereby the physics fundamental to the modalities
of cold, heat and ultrasound therapies was integrated in lectures and actual physiotherapy activities. The design of the course
is described together with the perceptions of physiotherapy students regarding the organisation of the course, safety aspects
and how well the integration contributed to their understanding of the physics involved in electrotherapy.

The aims of this study were to determine the underlying conceptual structure of the thermal concept evaluation (TCE) questionnaire, a pencil-and-paper instrument about everyday contexts of heat, temperature, and heat transfer, to investigate students’ conceptual understanding of thermal concepts in everyday contexts across several school years and to analyse the variables—school year, science subjects currently being studied, and science subjects previously studied in thermal energy—that influence students’ thermal conceptual understanding. The TCE, which was administered to 515 Korean students from years 10–12, was developed in Australia, using students’ alternative conceptions derived from the research literature. The conceptual structure comprised four groups—heat transfer and temperature changes, boiling, heat conductivity and equilibrium, and freezing and melting—using 19 of the 26 items in the original questionnaire. Depending on the year group, 25–55% of students experienced difficulties in applying scientific concepts in everyday contexts. Years of schooling, science subjects currently studied and physics topics previously studied correlated with development of students’ conceptual understanding, especially in topics relating to heat transfer, temperature scales, specific heat capacity, homeostasis, and thermodynamics. Although students did improve their conceptual understandings in later years of schooling, they still had difficulties in relating the scientific concepts to their experiences in everyday contexts. The study illustrates the utility of using a pencil-and-paper questionnaire to identify students’ understanding of thermal concepts in everyday situations and provides a baseline for Korean students’ achievement in terms of physics in everyday contexts, one of the objectives of the Korean national curriculum reforms. 相似文献

Why teachers use digital learning materials: The role of self-efficacy, subjective norm and attitude

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

Historic parchment is a complex biological material, and due to various methods of production or inks used, unknown environmental histories of objects and heterogeneous nature of animal skin, it represents a particular analytical challenge. Due to the number of variables it is likely that patterns in degradation of these historic objects can only be revealed by surveying the material properties of a significant number of real objects. In this work, a sacrificial collection of ca. 100 historic parchments (fifteenth to twentieth century) was characterized using a range of techniques available to conservation practitioners that can usefully be used to reliably and rapidly characterize parchment. We focused on micro-destructive methods, such as shrinkage temperature (Ts), as the most widely used indicator of parchment degradation. Lipid content, roughness, and ink pH were additionally measured, while a limited number of samples containing iron gall ink were also examined using scanning electron microscopy (SEM) and SEM-EDX, to explore the distribution of ink components. Even in the absence of detailed environmental histories, it is possible to acknowledge the significance of the effect of iron gall ink and its acidity, and of lipids on parchment degradation, as measured using Ts. This research reports valuable reference data, while the collection remains accessible for further research. 相似文献

The amount of data available in the context of educational measurement has vastly increased in recent years. Such data are often incomplete, involve tests administered at different time points and during the course of many years, and can therefore be quite challenging to model. In addition, intermediate results like grades or report cards being available to pupils, teachers, parents, and policy makers might influence future performance, which adds to the modeling difficulties. We propose the use of simple data filters to obtain a reduced set of relevant data, which allows for simple checks on the relative development of persons, items, or both. 相似文献

ABSTRACT The use of written knowledge tests in (medical) education is widespread. Only few of them are thoroughly validated. Usually, validity studies are restricted to establishing ‘face‐validity’, the apparent similarity between test‐material and real life problems. Reliability studies are usually restricted to estimation of the coefficient alpha, representing the reproducibility of rank‐ordering of students at repeated test administration. This study addresses reliability from a broader perspective, using generalizability theory. The approach enables faculty to gain insight into the suitability of the test to serve different educational goals. A written knowledge test was examined, applied in postgraduate training for general practice in the Netherlands. Test‐reliability was approached from different perspectives: the norm‐oriented perspective, aiming at rank‐ordering (groups of) students, the domain‐oriented perspective, aiming at determining the absolute score level of (groups of) students and the decision‐oriented perspective, aiming at taking pass‐fail decisions. Reliability estimates differed for the different perspectives. The implication of the results and feasible options to increase reliability are discussed. 相似文献

Many innovations in education are not completed, even if they are well thought out in advance. One of the main causes is the organization’s lack of learning ability, combined with a shortage of teachers’ and students’ ownership with respect to the renewal of ideas and design. In communities of learners, teachers and students collaborate and learn together in order to shape innovations in their daily practice. Their ability to learn collectively is a key factor in developing a learning organization. So far, insights into how processes of collective learning can be designed effectively, and which critical factors play a role, have been based on limited empirical research. This article’s goal is to contribute to the development of these insights, using the results of a study based on 48 cases of collective learning in communities of learners in primary schools and teacher education institutes. The results suggest that although collective learning rarely takes place in most cases, many outcomes are created that affect all community members. This leads to the conclusion that some participants create outcomes, not only on behalf of themselves but also on behalf of others. 相似文献

Assessment innovations require explicitly challenging teachers’ assessment conceptions. In changing towards outcome-based curricula, aligning formative to new summative assessments is a challenge. This study, conducted in Dutch Agricultural Vocational Education and its new outcome-based summative assessments, aims to provide concrete insights into what teacher conceptions hinder the development of aligned formative assessment practices. In a structured collaborative action research, practitioners, researchers and consultants analyse teachers’ formative practices, identify underlying current conceptions and their misalignment to the new summative assessment system. An iterative process resulted in an overview of current conceptions versus required conceptions, showing required conceptual changes that are prerequisite for teachers to change towards formative assessment practices that are aligned to the new outcome-based summative assessment system. 相似文献
