The aim of the present study was to understand the nature of teaching efficacy beliefs related to a socioscientific issue (SSI). We investigated Turkish preservice science teachers’ teaching efficacy beliefs about genetically modified (GM) foods using a belief system approach. We assumed that preservice teachers’ beliefs about GM foods (content knowledge, risk perceptions, moral beliefs, and religious beliefs) and their teaching efficacy beliefs about this topic constitute a belief system, and these beliefs are interrelated due to core educational beliefs. We used an exploratory mixed design to test this model. We developed and administered specific questionnaires to probe the belief system model. The sample for the quantitative part of this study included 441 preservice science teachers from eight universities. We randomly selected eight participants in this group for follow-up interviews. The results showed that preservice science teachers held moderately high teaching efficacy beliefs. Learning and teaching experiences, communication skills, vicarious experiences, emotional states, and interest in the topic were sources of this efficacy. In addition, content knowledge and risk perceptions were predictors of teaching efficacy. We believe that epistemologies based on traditional teaching and the values attached to science teaching are the core beliefs that affect the relationship between predictor variables and teaching efficacy. 相似文献

ABSTRACTThis study was conducted to propose and examine a comprehensive model embracing prospective teachers’ beliefs about self, teaching and learning conceptions, and attitudes towards using instructional technologies. Prospective or inservice teachers’ beliefs (from central to peripheral) and attitudes may empower the support of teacher training related to using instructional technologies. Participants were 1208 Turkish prospective teachers from five different universities who participated voluntarily and were selected using convenience sampling. Structural equation modelling analysis showed that prospective teachers’ beliefs about the autonomous self and autonomous–related self positively related to both their constructivist beliefs about teaching and learning and attitudes towards using instructional technologies, whereas the same beliefs negatively related to traditional conceptions of teaching and learning. Moreover, participants’ constructivist beliefs about teaching and learning positively predicted their attitudes towards using instructional technologies. Furthermore, their beliefs about related self positively and unexpectedly predicted their constructivist conceptions and attitudes. Implications are presented considering these results. 相似文献

ABSTRACTMouth rinsing has been proposed as a strategy to minimize performance decrements during Ramadan. We investigated the effect of 4 weeks of Ramadan on kicking performance in 27 Taekwondo athletes performing weekly Taekwondo Anaerobic Intermittent Kick Tests (TAIKT). The effects of a placebo, 6.4% glucose and 6-mg/kg caffeine mouth rinses on TAIKT performance and perceived exertion were investigated before, during weekly training sessions, and after Ramadan in a counterbalanced, crossover design. Ramadan had a significant negative impact on the percentage of successful kicks in Week 1 of Ramadan (pre: 76.7±0.4%, Week 1: 69.9±3.2%). The percentage of successful kicks was significantly greater in the caffeine mouth rinse condition compared to the glucose and placebo conditions during the first 3 weeks of Ramadan (caffeine: 38.3±6.8%, glucose: 36.4±6.9%, placebo: 36.0±6.5%). Caffeine decreased perceived exertion during Ramadan (0.74-1.15 AU, p>0.05). Our results showed that Ramadan had a significant negative effect on repeated high-intensity kicking efforts that should be considered when training and competing. Additionally, there were significant positive effects of a caffeine mouth rinse in a sport-specific test. These data suggest that athletes can consider mouth rinsing as a strategy to enhance performance when undertaking training or competition during a period of privation. 相似文献

One of the fundamental purposes of educational research is to provide evidence to facilitate effective practice. However, the evidence itself does not have much value for practitioners unless key information about the context from which the evidence was generated is also provided. In this paper, we use the word ‘context’ to refer to factors that are relevant for learning, including the interactions that learners experience with multiple people, artefacts, and environments. Unfortunately, in many educational research studies, either these factors do not get the required attention or information about them is presented in an incoherent structure. The resultant lack of information leads to two significant drawbacks. First, it creates confusion among practitioners who want to apply research evidence in their practice. Second, it leads to research studies that on the face of it are similar, but that in reality have resulted from evidence that has been collected in significantly different contexts being included under the same categories in reviews, meta-reviews, and best-evidence syntheses. In this paper, we draw on the concept of ‘relatability’ of evidence and present taxonomy for collaborative problem-solving (CPS) that can be used to provide the valuable information against which research evidence can be indexed. By addressing the need for more detailed information about the contextual factors from which the evidence is generated to bridge the gap between research and practice in CPS research, we aim to exemplify the approach that is needed in educational research more generally. 相似文献

The question: “What is an appropriate role for AI?” is the subject of much discussion and interest. Arguments about whether AI should be a human replacing technology or a human assisting technology frequently take centre stage. Education is no exception when it comes to questions about the role that AI should play, and as with many other professional areas, the exact role of AI in education is not easy to predict. Here, we argue that one potential role for AI in education is to provide opportunities for human intelligence augmentation, with AI supporting us in decision-making processes, rather than replacing us through automation. To provide empirical evidence to support our argument, we present a case study in the context of debate tutoring, in which we use prediction and classification models to increase the transparency of the intuitive decision-making processes of expert tutors for advanced reflections and feedback. Furthermore, we compare the accuracy of unimodal and multimodal classification models of expert human tutors' decisions about the social and emotional aspects of tutoring while evaluating trainees. Our results show that multimodal data leads to more accurate classification models in the context we studied. 相似文献

Background: Recently, there is a growing interest in independent learning approaches globally. This is, at least in part, due to an increased demand for so-called ‘21st century skills’ and the potential of independent learning to improve student skills to better prepare them for the future.
Purpose: This paper reports a study that explored the effectiveness of two different independent learning approaches: (i) guided independent learning and (ii) unguided independent learning with independent research, in enabling students in an undergraduate Macromolecules course to acquire knowledge in one chemistry context and apply it successfully in another.
Sample: The study involved 144 chemistry students commencing their first term of undergraduate study at a northern university in England. Students completed pre- and post-intervention tests containing 10 diagnostic questions, of which 4 measured students’ knowledge acquisition in one context and 6 measured their ability to apply it in another.
Design and methods: Diagnostic questions had been identified using a Delphi approach. Paired t-tests and chi-square tests were used to analyse the significance of any change in students’ responses to the diagnostic questions and the number of responses evidencing misconceptions, respectively.
Results: Whilst guided independent learning settings were found to improve students’ knowledge and ability to apply that knowledge in novel situations, unguided independent learning had no statistically significant effect. Unguided independent learning was also linked to a statistically significant increase in the number of student misconceptions in one of the diagnostic questions.
Conclusions: The results of this study show that guidance in independent learning activities is a key necessity for effective learning in higher education. This paper has strong relevance and high significance to tertiary STEM education, especially in the light of increased importance of teaching, such as the Teaching Excellence Framework in the UK, and shifts to more independent learning activities. 相似文献

EDUCATE is a London-based programme that supports the development of research-informed educational technology (EdTech), allowing entrepreneurs and start-ups to create their products and services, and simultaneously grow their companies in a more evidence-informed manner. The programme partners businesses with researchers who mentor, guide and support this research journey, a key aspect of which is the evaluation of the company’s EdTech product or service. However, conducting impact evaluations of technology in education is challenging, particularly for early stage technologies, as rapid cycles of innovation and change are part of their essence. Here, we present the pragmatic approach to evidence-informed education technology design and impact evaluation, as developed and adopted by the EDUCATE programme. The research process is shaped by the core principles of evidence-informed decision making detailed in the paper. The contributions of the paper are threefold. First, it defines and details an academia-industry-education collaboration model centred on a research training programme. Second, it presents emerging impact results of the programme. Third, it provides clear reflections on the challenges encountered during the implementation of the model in the EdTech ecosystem of London, which should be addressed if we are to move towards evidence-informed EdTech globally. 相似文献
