In this column, the authors reprise recent selections from the Lamaze International research blog, Science & Sensibility. Each selection discusses shortcomings in the news media coverage of childbirth issues. The authors demonstrate how to identify misleading claims in the media and highlight how childbirth educators can apply a common-sense approach and careful fact checking to help women understand the whole story. 相似文献

The purpose of this pilot study was to assess the potential for computer-assisted instruction (CAI) to enhance number combination skill among children with concurrent risk for math disability and reading disability. A secondary purpose was to examine the effects of CAI on spelling. At-risk students were assigned randomly to math or spelling CAI, which they received in 50 sessions over 18 weeks. Acquisition and transfer effects were assessed. The results indicated that math CAI was effective in promoting addition but not subtraction number combination skill and that transfer to arithmetic story problems did not occur. Spelling CAI effects were reliable on acquisition and transfer spelling measures, with small to moderate effect sizes on transfer to reading measures. These results provide the basis for additional work with larger samples. 相似文献

Person reliability parameters (PRPs) model temporary changes in individuals’ attribute level perceptions when responding to self‐report items (higher levels of PRPs represent less fluctuation). PRPs could be useful in measuring careless responding and traitedness. However, it is unclear how well current procedures for estimating PRPs can recover parameter estimates. This study assesses these procedures in terms of mean error (ME), average absolute difference (AAD), and reliability using simulated data with known values. Several prior distributions for PRPs were compared across a number of conditions. Overall, our results revealed little differences between using the χ or lognormal distributions as priors for estimated PRPs. Both distributions produced estimates with reasonable levels of ME; however, the AAD of the estimates was high. AAD did improve slightly as the number of items increased, suggesting that increasing the number of items would ameliorate this problem. Similarly, a larger number of items were necessary to produce reasonable levels of reliability. Based on our results, several conclusions are drawn and implications for future research are discussed. 相似文献

We believe that the ideas associated with the Maker Movement have profound implications for teacher education. We have isolated the pedagogical principles of hack, adapt, design, and create as central to exploring how they work with teacher candidate participants in a maker pedagogy lab. We frame these ideas as Maker Pedagogy, which is the enactment of the principles inspired by the maker movement in the classroom to foster learners who operate as innovators, creators, sharers and givers of knowledge, tools and technologies. The purpose of our self-study research is to describe, interpret and analyze how our pedagogies of teacher education and our critical friendship have changed and developed as a result of providing experiences for teacher candidates in our maker pedagogy lab. In this project we use self-study methodology to investigate our teaching and practices, and we dialogue about our tacit and personal knowledge as it contributes to the knowledge and understanding of our teaching through Maker Pedagogy. In particular, the emphasis is on critical collaborative inquiry through critical friends and on dialogue as a valued component of our research. Of particular interest were data in the video recordings of each lab that indicated that one or both of us had reframed our understanding of maker pedagogy. The findings are framed as three themes that document what we are learning about Maker Pedagogy through teaching teacher candidates. These are (1) the value of self-study methodology, (2) Maker Pedagogy as distinct and (3) deepening our pedagogies of teacher education. 相似文献

To maximize the advantages of the tablet personal computer (TPC) at school, this technology needs to be accepted by students as new tool for learning. With reference to the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology, the aims of this study were (a) to analyze factors influencing high school students' acceptance of TPCs and (b) to detect any difference in this influence considering the frequency of TPC use, students' gender, and school grade. Two hundred and ninety-six students from six high schools in the Milan area participated in the study. Data were collected using an online survey. The results showed that empowerment in learning, perceived usefulness, and support conditions affect learning use, and empowerment in learning and affect influence communicative use of TPCs. The implications of these results are discussed. (Keywords: tablets, acceptance, digital technologies, high school, path analysis) 相似文献

This study examined the physical differences in adult male basketball players of different competitive level and playing position using a large cohort. In the middle of the regular season, 129 players from four different Divisions completed a Yo-YoIR1 and, after 3-to-8 days, they performed a 6-min continuous running test (Mognoni’s test), a counter-movement jump (CMJ) test and a 5-min High-intensity Intermittent running test (HIT). Magnitude-based inferences revealed that differences in HIT were very likely moderate between Division I and II and likely small between Division II and III. The differences in absolute peak power and force produced during CMJs between Division I and II and between Division II and III were possibly small. Differences in Yo-YoIR1 and Mognoni’s test were very likely-to-almost certain moderate/large between Division III and VI. We observed possibly-to-likely small differences in HIT and Mognoni’s test between guards and forwards and almost certainly moderate differences in absolute peak power and force during CMJs between guards and centres. The ability to sustain high-intensity intermittent efforts (i.e. HIT) and strength/power characteristics can differentiate between competitive level, while strength/power characteristics discriminate guards from forwards/centres. These findings inform practitioners on the development of identification programs and training activities in basketball. 相似文献

Despite the growing interest, Open Innovation (OI) in Intangible Assets (IAs) research is still fragmented and displays a limited contextual focus. This paper aims to provide a clearer view of these issues and represents a first step toward filling such research gap. A systematic literature review and a synthesis of high-quality contributions with a focus on a general overview of research on OI and IAs in OI processes have been carried out. By critically evaluating the current body of literature and definitions, we have moved a step further toward comprehending the multiple facets of existing research and highlight several promising areas for future development. In particular, we have analyzed the role of IAs in OI practices by selecting a synthesis and a critical review of their different exploitations. We have combined multiple algorithms to produce a clear topical taxonomy of the multiple strands of research lying at the interface of OI and IAs. 相似文献
