There Have been many attempts to discover what has happened to the Germans and Germany during the last decade. All these attempts have been more or less successful. The impossibility of giving a satisfactory explanation is due to the complexity of the “German Soul” and the conflicts within it; hardly any other people have the same significance inthat respect. This, perhaps, is also the best explanation for the apparently entire success of Hitler and his theories. 相似文献
Alkaline haemoglobin electrophoresis is a useful tool in diagnosing β-thalassemia and sickle-cell anaemia. In this report,
using this simple technique, β-thalassemia associated with sickle-cell anaemia is diagnosed. This is the first case we have
diagnosed in our laboratory using agarose gel electrophoresis. 相似文献
As teachers' knowledge determines to a large extent how they respond to educational innovation, it is necessary for innovators
to take this knowledge into account when implementing educational changes. This study aimed at identifying patterns in the
content and the structure of science teachers' knowledge, at a point in time when they still had little experience in teaching
a new subject, that is, Public Understanding of Science. We investigated three domains of teacher knowledge: Teachers' pedagogical
content knowledge (PCK), subject-matter knowledge, and general pedagogical knowledge. A semi-structured interview and a questionnaire
were used. From the analysis of the data, two types of teacher knowledge emerged. One of the types was more integrated and
more extended in terms of PCK. Teachers who represented this type of knowledge had developed PCK that connected the various
programme domains of the new science subject. In both types, PCK was found to be consistent with general pedagogical knowledge.
In both types, however, subject-matter knowledge was similar, and not directly related to the other knowledge domains. Implications
for the implementation of the new subject are discussed. 相似文献
The intersection of teacher beliefs with writing achievement in schooling is a key concern of this paper. The paper reports part of a two‐year Australian study that set out to examine in detail how it is that teachers judge Year 5 students' literacy achievement using writing as the case instance. In what follows, we examine the data in the form of concept maps that the teachers them selves made available showing their beliefs about, and insights into the factors that affect student writing achievement. Drawing on these maps, we highlight the range of teacher‐identified factors, including those relating to in‐class behaviour, motivation, attitudes to school learning, social and cultural backgrounds, oracy and even life circumstances. Additionally, we address how the identified factors function, operating either as standalone elements or within a dynamic network of inter‐relationships. 相似文献
Research and design activities are important focus points in international policies for secondary Science, Technology, Engineering and Mathematics (STEM) education. It is up to school teachers to implement and supervise these activities in the STEM classroom. However, not much is known about the attitudes teachers hold towards supervising research projects or design projects. In this study, a questionnaire to measure teacher attitudes towards supervising research activities and design activities in secondary school was completed by 130 Dutch teachers who taught the relatively new Dutch STEM subjects O&O (research and design) and NLT (nature, life, and technology). These integrated STEM subjects are project and context based and are taught in a limited number of schools. Important differences between these integrated STEM subjects are their student and teacher populations: NLT is taught in grades 10–12 by teachers with a qualification in a science subject, while O&O is taught in grades 7–12 and can be given by any teacher in secondary school. The results showed that on average, both O&O and NLT teachers had high self-efficacy scores on supervising research and design projects even when they had received no special education in doing so. Furthermore, the teachers in general viewed supervising research projects as a more relevant activity than supervising design. Since research and design activities are becoming more important in (inter)national curriculum standards, STEM teacher education and subsequent professional development should not only familiarize teachers with supervising research projects, but with design projects as well.
The current study investigates whether embedding support may provide a solution to sub optimal use of support and whether
this is related to learners’ self-regulation skills and goal orientation. Sixty students were divided in a condition where
support was embedded and a condition where support was non-embedded. Results reveal that the embedded group used more and
spent more time on the use of support. Quality of use differed for one support device only, with quality being higher in the
non-embedded group. An interaction with self-regulation was found. High self-regulators use the support devices less optimal
when support is embedded. No conclusions could be drawn with respect to goal orientation. Quality of usage and proportional
time spent on support influenced learning outcomes. 相似文献
School playgrounds offer everyday opportunities for physically active and social play that combats obesity, develops skills, and promotes well‐being. However, teachers’ fear of the legal consequences of injury can elicit over‐zealous risk reduction with the result that playgrounds lack challenge, and the potential benefits of play become limited. In this research, we trialled a simple, cost‐effective strategy to encourage children to be more active and social on a school playground. Over 11 weeks, we made available materials with no fixed purpose (e.g. car tires, boxes) to a playground of children aged five to seven. Accelerometers showed children became significantly more active. Interviews with teachers suggested children also became more social, creative, and resilient. However, despite no incidence of injuries, teachers perceived an increased risk and encountered dilemmas regarding duty of care. We conclude that future interventions should address issues of ‘surplus safety’ at individual, school, system, and policy levels. 相似文献
