It is well established that technological education is not just about the development of technical expertise. A socially constructed view of technology aims to recognise the culture of technology. Technology education as expressed in the New Zealand curriculum provides an opportunity for societal issues to have equal space with technological capability and technological knowledge. However, when technological activities focus on solutions it is all too easy for stakeholders' positions to be ignored. There is a need for a teaching approach to engage in a liberating technological literacy discourse where values and beliefs of all participants directly and indirectly involved in the activity, are examined. This research monitored a professional development programme where identification of the values represented in a familiar object provided a model for discussion and the development of a teaching environment that promoted consideration of values during problem-solving. The data have been collected from primary school teachers who developed teaching programmes for Years 1 to 8 (5–12 years).  相似文献

The aim of the study was to investigate progress in reasoning capacity and knowledge base appraisal in a longitudinal analysis of data from summative evaluation throughout a medical problem-based learning curriculum. The scores in multidisciplinary discussion of a clinical case and multiple choice questionnaires (MCQs) were studied longitudinally for 213 students from years 2 to 5. The capacity of core knowledge delimitation was calculated as the difference between the levels of average ascertainment degrees given for correct and incorrect answers at MCQ. For both multidisciplinary discussion of a clinical case evaluation and self-estimation of core knowledge, the capacity increases throughout the curriculum. The reasoning capacity assessed through multidisciplinary discussion of a clinical case is positively correlated with MCQ scores and the capacity to discriminate the mastered core knowledge. In conclusion, this study indicates that self-estimation of core knowledge is associated with an increase in reasoning performance through a well-organised knowledge base. Since that ability is related to success or failure, it is suggested that student awareness about delimitation of mastered core knowledge is considered as part of learning.  相似文献

This paper demonstrates and discusses the use of think aloud protocols (TAPs) as an approach for examining and confirming sources of differential item functioning (DIF). The TAPs are used to investigate to what extent surface characteristics of the items that are identified by expert reviews as sources of DIF are supported by empirical evidence from examinee thinking processes in the English and French versions of a Canadian national assessment. In this research, the TAPs confirmed sources of DIF identified by expert reviews for 10 out of 20 DIF items. The moderate agreement between TAPs and expert reviews indicates that evidence from expert reviews cannot be considered sufficient in deciding whether DIF items are biased and such judgments need to include evidence from examinee thinking processes.  相似文献

The purpose of this study was to evaluate the impact of the Gaining Early Awareness and Readiness for Undergraduate Program (GEAR UP) on college readiness outcomes using a quasi-experimental design. GEAR UP is designed to increase the number of low-income students who are prepared to enter and succeed in postsecondary education by providing 6-year grants to states and district partnerships to provide services at high-poverty middle and high schools. Specifically, this study sought to evaluate whether 173 schools that participated in GEAR UP showed increases in the percentages of students who were prepared to enter and succeed in postsecondary education, as compared to students from similar, non-GEAR UP schools. Seven years (2003–2009) of matched cohort data were compiled to include all regular (e.g., nonspecial education) high schools with grade 12 enrollment as documented by the National Center for Educational Statistics. Participation in and performance on three College Board assessments that measure college readiness at the high school level (SAT, PSAT/NMSQT, and AP) as well as percent free/reduced-price lunch were used to identify comparable schools. Results showed that, overall, the GEAR UP program showed positive evidence of improving college readiness outcomes for low income students using a variety of college readiness measures.  相似文献

This study compared private speech of children with ADHD and normal controls during problem solving and inhibition tasks. Thirty-two children (16 children with ADHD and 16 matched controls) aged 6–11 years participated. Consistent with previous studies, children with ADHD produced more task-irrelevant and task-relevant external private speech than control children during problem-solving tasks, but did not differ in their use of task-relevant internal private speech. During the inhibition/attention task (Continuous Performance Test-II), children with ADHD produced more task-relevant external and more task-relevant internal private speech, suggesting that they may have employed a less mature strategy to aid in self-regulation. The educational implications of the current study are that there should be an increased awareness of the developmental nature and functional significance of private speech and how private speech usage may differ in children with ADHD.  相似文献

The aim of this pilot study is to analyse the discourse of fathers of toddlers concerning fatherhood and the link between some particularities in the discourse and family alliance. The sample consists of 13 Swiss first time fathers (5 fathers of girls and 8 of boys). In order to evaluate the paternal discourse, the fathers were given a semistructured interview, which was later analysed using the research package Alceste. The family alliance, i.e., the degree of coordination among the partners when executing a task together, was assessed through the Lausanne Trilogue Play (Fivaz-Depeursinge & Corboz-Warnery, 1999). The main results indicated an interesting link between classes of paternal discourse grouped around the following themes “affective relationship”, “daily routine” and “educational goals”, and the family alliance (defined in two major categories; functional and problematic alliances). Finally, clinical perspectives on links between paternal representations and family functioning at an interactive level are discussed.  相似文献

A group of preservice primary teachers (46) in their third year of a Bachelor of Education degree were overtly taught the nature of science (NOS) and nature of technology (NOT) within an authentic context of the issues of UV radiation. The research question asked was, ‘What characteristics of NOS and NOT are identified, illustrated and justified within an authentic context by the preservice teachers?’ This context was accessed via a web-based resource, ‘You, Me and UV’ (www.sciencelearn.org.nz), which provided preservice teachers with virtual access to the science research community. The goal of this research was to explore the potential of providing a virtual authentic resource, accompanied by explicit teaching of NOS and NOT, to develop preservice teachers' understandings of NOS and NOT. A data collection instrument where preservice teachers were required not only to identify examples of NOS and NOT, but also to justify and contextualise them from this context, was able to capture their level of understanding. It also showed the potential of an authentic context and the possibilities of a virtual resource to provide access to communities of practice of science and technology research.  相似文献
