An important task of science teachers should be to take pupils’ (pre)conceptions and learning difficulties into account and to negotiate about the meanings of specific concepts. In this context, teachers’ pedagogical content knowledge plays an important role. This article presents an international study of Dutch, Finnish, English and Greek pre-service teachers’ conceptions and concerns of how to teach the concept of combustion. The prospective science teachers were invited to prepare a lesson about this concept for pupils of junior secondary school level. The prospective teachers were not allowed to consult any textbook. Research data were obtained from audio-taped semi-structured interviews with the prospective teachers. In addition, their written lesson plans and their answers to an accompanying questionnaire were collected and analysed. The results reveal a number of important characteristics of prospective teachers’ views and concerns regarding the teaching of combustion. The implications of the study for science teacher education will be presented. 相似文献

Richard Rose, Senior Lecturer at University College, Northampton, and Will Fletcher and Gaynor Goodwin, Watling View School, St Albans, argue that although many schools have attempted to enable pupils with special educational needs to play an active part in their own planning procedures and assessment, few have identified and analysed the skills required by both pupils and teachers. Theydescribe a one-year small-scale action-research project, in a school for children with severe learning difficulties, which resulted in the development of procedures for the assessment of 'pupil readiness' for full involvement in the target-setting process. 相似文献

A meta-analysis of morphological interventions: effects on literacy achievement of children with literacy difficulties 总被引:2,自引:0,他引:2
This study synthesizes 79 standardized mean-change differences between control and treatment groups from 17 independent studies,
investigating the effect of morphological interventions on literacy outcomes for students with literacy difficulties. Average
total sample size ranged from 15 to 261 from a wide range of grade levels. Overall, morphological instruction showed a significant
improvement on literacy achievement ([`(d)] \overline d = 0.33). Specifically, its effect was significant on several literacy outcomes such as phonological awareness ([`(d)] \overline d = 0.49), morphological awareness ([`(d)] \overline d = 0.40), vocabulary ([`(d)] \overline d = 0.40), reading comprehension ([`(d)] \overline d = 0.24), and spelling ([`(d)] \overline d = 0.20). Morphological instruction was particularly effective for children with reading, learning, or speech and language
disabilities, English language learners, and struggling readers, suggesting the possibility that morphological instruction
can remediate phonological processing challenges. Other moderators were also explored to explain differences in morphological
intervention effects. These findings suggest students with literacy difficulties would benefit from morphological instruction. 相似文献

Delivering public services through the SMS channel is popular in developed and developing countries, and it has demonstrated its benefits. However, citizens' acceptance of the services is still an issue. This paper presents a study on user acceptance of SMS-based e-government services. Constructs of the proposed model were derived from a survey on citizens' motivations for using SMS-based e-government services (142 respondents from 25 countries), prominent theories on individual acceptance of technologies, and current studies on user acceptance of SMS and e-government services. The model was validated using data from 589 citizens in three cities in Indonesia, who are non-adopters. The relationships between the factors then were compared with data from 80 adopters of SMS-based e-government services in Australia. The proposed model explains what factors influence non-adopters to accept SMS-based e-government services, and the comparison explains the relative importance of the factors for the adopters. The findings are promising for governments who wish to evaluate a new SMS-based e-government system very early in its development in order to assess potential acceptability and for governments who would like to diagnose the reasons why an existing SMS-based e-government service is not fully acceptable to citizens and to take corrective action to increase the acceptability of the service. 相似文献

A controlled experiment was conducted in forty-four fifth-grade classrooms to investigate the extent to which creativity and problem-solving skills of children could be nurtured through a series of self-instructional programmed lessons. Also studied was the relationship of such skills to (1) learner characteristics (IQ and sex) and (2) classroom “environment” as it may have facilitated creative thinking. Significant differences were found favoring the experimental group (which received the programmed lessons). Improvement in productive thinking skills was found for both boys and girls of both higher and lower IQ. Greater gains were found in classrooms providing relatively little support and encouragement for productive thinking. Also the performance of girls on the productive thinking measures exceeded that of boys and there was a strong positive relationship to IQ. 相似文献

While prior meta-analyses in anatomy education have explored the effects of laboratory pedagogies and histology media on learner performance, the effects of student-centered learning (SCL) and computer-aided instruction (CAI) have not been broadly evaluated. This research sought to answer the question, “How effective are student-centered pedagogies and CAI at increasing student knowledge gains in anatomy compared to traditional didactic approaches?” Relevant studies published within the past 51 years were searched using five databases. Predetermined eligibility criteria were applied to the screening of titles and abstracts to discern their appropriateness for study inclusion. A summary effect size was estimated to determine the effects of SCL and CAI on anatomy performance outcomes. A moderator analysis of study features was also performed. Of the 3,035 records screened, 327 underwent full-text review. Seven studies, which comprised 1,564 participants, were included in the SCL analysis. An additional 19 studies analyzed the effects of CAI in the context of 2,570 participants. Upon comparing SCL to traditional instruction, a small positive effect on learner performance was detected (standardized mean difference (SMD = 0.24; [CI = 0.07, 0.42]; P = 0.006). Likewise, students with CAI exposure moderately outscored those with limited or no access to CAI (SMD = 0.59; [CI = 0.20, 0.98]; P = 0.003). Further analysis of CAI studies identified effects (P ≤ 0.001) for learner population, publication period, interventional approach, and intervention frequency. Overall, learners exposed to SCL and supplemental CAI outperformed their more classically-trained peers as evidenced by increases in short-term knowledge gains.

Validity of the VmaxST portable metabolic measurement system 总被引:1,自引:0,他引:1
Laurent CM Meyers MC Robinson CA Strong LR Chase C Goodwin B 《Journal of sports sciences》2008,26(7):709-716
The aim of this study was to assess and compare the validity of the portable VmaxST telemetry metabolic measurement device with that of a standard measurement system (Vmax29). Thirty asymptomatic, moderately active males provided written, informed consent and completed two maximal graded treadmill exercise tests (Bruce) using the VmaxST and the Vmax29 metabolic measurement systems. Tests were performed in random order on separate days to obtain peak values for time to exhaustion, heart rate, systolic and diastolic blood pressure, oxygen consumption (VO2), carbon dioxide production (VCO2), ventilation (VE), and respiratory exchange ratio (RER). Multivariate analysis of variance revealed no significant main effect (P = 0.88) between the two systems across any variable, suggesting similar measurement capabilities between the two systems. Linear regression analyses revealed moderate to high coefficients of determination for VO2 (r2 = 0.99), VCO2 (r2 = 0.99), VE r2 = 0.99), and RER (r2 = 0.89). Furthermore, Bland-Altman analyses demonstrated that the VmaxST yielded similar values to the Vmax29, suggesting good agreement between the two systems. Agreement was confirmed when the differences between the methods resulted in a small range as identified by the 95% limits of agreement. Findings from the current study confirm that the VmaxST is a valid device for measuring metabolic and physiological variables during exercise within a controlled laboratory setting. 相似文献
