Making agency matter: rethinking infant and toddler agency in educational discourse

This article engages critically with the concept of agency in infant and toddler educational discourse. It is argued that agency, when conceptualised with emphasis on individuality and the autonomous self, poses a conceptual ‘dead end’ for those who are not-yet-in-language, such as babies and toddlers. In considering agency as an aspect of becoming that is inherent in all matter, the article seeks to explore new pathways for conceptualising agency in infant and toddler education. Methodologically, the article aims to generate complex questions and, following Nigel Thrift's call, ‘wild ideas’, rather than solutions by addressing the relationship between discourse and matter to open up new spaces for thinking and doing ‘agency’ in education, for babies and toddlers and beyond.     

Evaluating the Responsiveness of Accelerometry to Detect Change in Physical Activity

The responsiveness to change of the Actical and ActiGraph accelerometers was assessed in children and adolescents. Participants (N = 208) aged 6 to 16 years completed two simulated free-living protocols, one with primarily light-to-moderate physical activity (PA) and one with mostly moderate-to-vigorous PA. Time in sedentary, light, moderate, and vigorous PA was estimated using 8 previously developed cut-points (4 for Actical and 4 for ActiGraph) and 5-sec, 15-sec, and 30-sec epochs. Accelerometer responsiveness for detecting differences in PA between protocols was assessed using standardized response means (SRMs). SRM values ≥.8 represented high responsiveness to change. Both accelerometers showed high responsiveness for all PA intensities (SRMs = 1.2–4.7 for Actical and 1.1–3.3 for ActiGraph). All cut-points and epoch lengths yielded high responsiveness, and choice of cut-points and epoch length had little effect on responsiveness. Thus, both the Actical and ActiGraph can detect change in PA in a simulated free-living setting, irrespective of cut-point selection or epoch length.     

Mother–child joint writing in Chinese kindergarteners: metalinguistic awareness,maternal mediation and literacy acquisition

The present study examined the relations of Chinese word reading and writing to both maternal mediation of writing and a number of metalinguistic and cognitive skills in 63 Hong Kong Chinese kindergarteners. The whole process of maternal mediation of writing, in which mothers individually facilitated their children's writing of 12 two‐character words in their own ways, was videotaped. This study replicated and extended previous work on the cognitive strategies mothers use to help children in writing Chinese words. Mothers' typical mediation strategies were positively and significantly associated with both children's independent word reading and writing. In addition, maternal mediation of writing was uniquely associated with Chinese word reading, but not word writing, even with metalinguistic and cognitive skills, including phonological awareness, morphological awareness, orthographic processing and visual knowledge, statistically controlled. Findings underscore the importance of mothers' early scaffolding in facilitating children's literacy acquisition.     

世代特征，信息环境变迁与大学生信息素养教育创新

当前世代大学生偏好的教育活动是个性化服务,电子媒介交互式学习,任务参与型学习甚至自主的学习;他们具备一定的信息素养能力,但差异巨大。本文指出:随着Internet技术及应用的深入发展,大学生信息素养能力包括三个层次,低层次是信息检索技能,然后是批判性思维能力和与自己专业密切相关的IT能力,更高层次是独立思考、认识论认知能力,最终达到解决实际问题的目的;高校图书馆已经不能独立满足学生多层次信息素养能力的要求及当前世代大学生对教育培训的偏好。本文提出信息素养教育五分策略:培养目标分层,教学内容分级,学科专业分类,培养过程分段,学生管理分流,并建议从网络课堂、图书馆、学院、学校、教育部、第三方平台等多个层面,共同推动我国大学生信息素养教育。图3。表3。参考文献63。     

Systematic Comparison of Decision Accuracy of Complex Compensatory Decision Rules Combining Multiple Tests in a Higher Education Context

This real‐data‐guided simulation study systematically evaluated the decision accuracy of complex decision rules combining multiple tests within different realistic curricula. Specifically, complex decision rules combining conjunctive aspects and compensatory aspects were evaluated. A conjunctive aspect requires a minimum level of performance, whereas a compensatory aspect requires an average level of performance. Simulations were performed to obtain students' true and observed score distributions and to manipulate several factors relevant to a higher education curriculum in practice. The results showed that the decision accuracy depends on the conjunctive (required minimum grade) and compensatory (required grade point average) aspects and their combination. Overall, within a complex compensatory decision rule the false negative rate is lower and the false positive rate higher compared to a conjunctive decision rule. For a conjunctive decision rule the reverse is true. Which rule is more accurate also depends on the average test reliability, average test correlation, and the number of reexaminations. This comparison highlights the importance of evaluating decision accuracy in high‐stake decisions, considering both the specific rule as well as the selected measures.
