Process evaluation of implementing knowledge management tools in public health

Translating formal and informal knowledge into public health (PH) action is essential given that PH professionals rely on up-to-date and context-specific information for effective programme planning, implementation, and evaluation. Knowledge management (KM) provides possible solutions to this challenge. We conducted an evaluation of a pilot implementation of four KM tools: (1) After Action Review; (2) Communities of Practice; (3) Peer Assist and; (4) Organizational Yellow Pages. The evaluation focused on fidelity, feasibility, and acceptability of the tools. Three main messages emerged from the study findings: (1) KM tools can be implemented in a PH context for the sharing of explicit and tacit knowledge, (2) enabling organizational environments were important for implementation, and (3) the provision of a facilitator during the implementation period was also important and appreciated by study participants.     

Classroom dialogue: a systematic review across four decades of research

Recognizing that empirical research into classroom dialogue has been conducted for about 40?years, a review is reported of 225 studies published between 1972 and 2011. The studies were identified through systematic search of electronic databases and scrutiny of publication reference lists. They focus on classroom dialogue in primary and secondary classrooms, covering the full age range of compulsory schooling. The methods of data collection and analysis used in the studies are described and discussed, with changes and continuities over time highlighted. Study results are then summarized and integrated to present a succinct picture of what is currently known and where future research might profitably be directed. One key message is that much more is known about how classroom dialogue is organized than about whether certain modes of organization are more beneficial than others. Moreover, epistemological and methodological change may be required if the situation is to be remedied.     

我国高校辅导员专业化发展中的问题与对策研究

随着社会分工的不断细化,高校辅导员职业逐渐呈现出专业化的发展趋势。它要求辅导员从事务性工作中提升出来,成长为学生思想政治教育与管理工作的理论研究者和方法论探索者。这符合新形势下高校学生思想政治教育与管理工作发展的新要求。本文客观分析了我国高校辅导员专业化发展的背景与现状,总结了其中还存在的一些问题,并在此基础上从教育政策、高校资源以及辅导员自身三个层面有针对性地提出了问题突破的对策。     

Socioeconomic status, parental investments, and the cognitive and behavioral outcomes of low-income children from immigrant and native households

The current study examines the effects of socioeconomic status (SES) on preschool children's cognitive and behavioral outcomes and if these relations are mediated by the quality of children's home environment and moderated by family nativity status. Data come from 1459 low-income families (n = 257 and 1202 immigrant and native families, respectively). Results indicated that among both immigrant and native households, maternal education, as compared to household income or welfare receipt, was the strongest predictor of a composite of SES. Path analyses estimated direct and indirect effects of SES and revealed greater similarity than difference in the processes by which SES influences immigrant and native children's preschool outcomes. Language/literacy stimulation and maternal supportiveness mediated the relations of SES to children's cognitive outcomes among both immigrant and native families. In contrast, parenting stress mediated the effects of SES on children's aggressive behavior among native, but not immigrant, households.

Supporting Conceptual Change in School Science: A possible role for tacit understanding

When students reason during school science, they often refer to conceptions that are derived from out-of-school experiences and are poor proxies for science orthodoxy. However, for some areas of science, these conceptions represent only a proportion of students' full conceptual knowledge, for tacit understanding exists that is superior to the understanding displayed when reasoning. Noting that tacit understanding is engaged when events are judged as natural or non-natural, the paper is concerned with software that: (a) requires direction and speed of falling objects to be predicted, i.e. a typical science reasoning task that engages conceptual knowledge; (b) presents simulations of predicted motion in the expectation that its naturalness or non-naturalness would be recognised. An evaluation study is reported where children aged 8–12 years worked with the software in contexts that typify computer use in classrooms, i.e. individually under adult guidance (n =? 44 children) or in pairs with a classmate (n = 48 children). They were observed while they did this. Reasoning about object fall was assessed via change from individual pre-tests administered prior to software usage to individual post-tests administered a few weeks afterwards. The children who worked with the software showed greater pre- to post-test gains in conceptual understanding than control children (n =? 47 children), who lacked software experience. The gains were especially marked for the children who worked in pairs. The approach taken is contrasted with traditional approaches to conceptual change in school science, e.g. strategies that rely upon classroom experiments.     

Hands-on Activities and Their Influence on Students’ Interest

This study investigates the influence of hands-on activities on students’ interest. We researched whether students with experience in specific hands-on activities show higher interest in these activities than students without experience. Furthermore, the relationship between the quality of the hands-on experience and interest in the respective activity was examined. In total, 28 typical hands-on activities of biology education were considered. The activities were divided into the categories experimentation, dissection, work with microscopes, and classification. A total of 141 students from the 11th grade completed questionnaires on interest in the hands-on activities, their experience with each activity, and the quality of the respective experience. Students’ interest in experimenting, working with microscopes, dissecting and classifying tends to benefit from performing hands-on activities. However, findings indicated that the performance of various hands-on activities can influence students’ interest differently. For seven hands-on activities, we identified a positive effect of hands-on experience on interest, while in one case, practical work appeared to have influenced students’ interest negatively. However, for most hands-on activities, no effect of experience on interest was found. The quality of hands-on experiences showed positive correlations with interest in the respective hands-on activities. Therefore, this paper argues in favour of designing biology lessons that allow for experiences with hands-on activities that also interest students. Our findings underline the necessity of investigating the effects of various hands-on activities in a differentiated manner.     

Dopamine Receptor D2 Polymorphism Moderates the Effect of Parental Education on Adolescents' School Performance

ABSTRACT— High parental socioeconomic status is known to have a positive effect on students' academic achievement. We examined whether variation in the dopamine receptor gene (DRD2 polymorphism, rs 1800497) modifies the association between parental educational level and school performance in adolescence. The participants were a randomly selected subsample of individuals participating in the Cardiovascular Risk in Young Finns study (921 girls and 742 boys) aged 12–15 years at the time school performance was assessed. The genotyping was performed using TaqMan 5'-nuclease assay. A significant interaction was found between childhood parental educational level and students' DRD2 polymorphism on academic achievement after adjustment for age, gender, household income, parental occupation, maternal nurturance, hyperactivity, and sociability. Parental educational level was significantly positively associated with school achievement in the A2/A2 ( n  = 1,061) and the A1/A2 ( n  = 529) genotype groups, but was negative and statistically insignificant in participants carrying the A1/A1 ( n  = 73) genotype. It is concluded that the extent to which parental education status affects an individual's academic achievement may be dependent on the individual's genetic constitution. The findings may increase an acceptance of genetic influence in education, and, consequently, may increase accurateness of educational interventions.
