As hypermedia, online teacher professional development (TPD) should ideally support diverse learners to work with online content
effectively because it involves multiple representations and a nonlinear format. Differences among participants in motivation
and learning provide challenges for design. The present study is a use-inspired, mixed-method study of 164 teachers’ motivation
and learning in an unmoderated online workshop. It addresses participants’ demographic and motivational profiles, participation
in this type of workshop (e.g., the frequency, duration, and focus, as well as their work with technology-enhanced, nonroutine
challenge problems and journal assignments), the predictive value of the initial questionnaire, and implications for design.
Findings indicate that while three clusters of motivational profiles could be identified (low interest, low self-efficacy,
and less math; low interest, high self-efficacy, and more math; high interest, high self-efficacy, and more math), whether
the teachers continue to participate appears to be related to the structure and content of the workshop, not just these profiles.
Findings are interpreted as suggesting that the potential of hypermedia lies in its designers’ abilities to support participant
stake by providing for multiple ways into thinking and working with disciplinary content—design that both accommodates and
supports those with differing strengths and needs. Implications for studying motivation and learning online are also discussed. 相似文献

Genetic and environmental influences on prereading skills in preschool and on early reading and spelling development at the
end of kindergarten were compared among samples of identical and fraternal twins from the U.S. (Colorado), Australia, and
Scandinavia. Mean comparisons revealed significantly lower preschool print knowledge in Scandinavia, consistent with the relatively
lower amount of shared book reading and letter-based activities with parents, and lack of emphasis on print knowledge in Scandinavian
preschools. The patterns of correlations between all preschool environment measures and prereading skills within the samples
were remarkably similar, as were the patterns of genetic, shared environment, and non-shared environment estimates: in all
samples, genetic influence was substantial and shared environment influence was relatively weak for phonological awareness,
rapid naming, and verbal memory; genetic influence was weak, and shared environment influence was relatively strong for vocabulary
and print knowledge. In contrast, for reading and spelling assessed at the end of kindergarten in the Australian and U.S.
samples, there was some preliminary evidence for country differences in the magnitude of genetic and environmental influences.
We argue that the apparently higher genetic and lower shared environment influence in the Australian sample was related to
a greater emphasis on formal reading instruction, resulting in more advanced reading and spelling skills at the end of kindergarten,
and thus there was greater opportunity to observe genetic influences on response to systematic reading instruction among the
Australian twins. 相似文献

This study investigated what 13 secondary science teachers at various nature of science (NOS) instruction implementation levels talked about when they reflected on their teaching. We then determined if differences exist in the quality of those reflections between high, medium, and low NOS implementers. This study sought to answer the following questions: (1) What do teachers talk about when asked general questions about their pedagogy and NOS pedagogy and (2) what qualitative differences, if any, exist within variables across teachers of varying NOS implementation levels? Evidence derived from these teachers’ reflections indicated that self-efficacy and perceptions of general importance for NOS instruction were poor indicators of NOS implementation. However, several factors were associated with the extent that these teachers implemented NOS instruction, including the utility value they hold for NOS teaching, considerations of how people learn, understanding of NOS pedagogy, and their ability to accurately and deeply self-reflect about teaching. Notably, those teachers who effectively implemented the NOS at higher levels value NOS instruction for reasons that transcend immediate instructional objectives. That is, they value teaching NOS for achieving compelling ends realized long after formal schooling (e.g., lifelong socioscientific decision-making for civic reasons), and they deeply reflect about how to teach NOS by drawing from research about how people learn. Low NOS implementers’ simplistic notions and reflections about teaching and learning appeared to be impeding factors to accurate and consistent NOS implementation. This study has implications for science teacher education efforts that promote NOS instruction. 相似文献

The assertion that general reform-based science teaching practices (GRBSTPs) can facilitate nature of science (NOS) instruction has been mentioned in the literature, but rigorous and transparent empirical substantiation for this claim has not been made. This investigation empirically demonstrates an association between thirteen experienced teachers’ NOS implementation practices and their GRBSTPs. While effectively implementing GRBSTPs does not ensure the NOS will be taught, the findings show that these practices are associated with high levels of NOS instruction. In this study, teachers who implemented higher levels of reform-based practices were also observed to enact more instances of planned and spontaneous effective NOS instruction. Furthermore, these teachers were more likely to recognize and capitalize on NOS teaching opportunities when they unexpectedly arose in the context of their GRBSTPs. Just as NOS understanding must be assessed when determining factors associated with teachers’ NOS implementation, teachers’ GRBSTPs should also be empirically and transparently established to ensure they do not mask or confound other factors associated with NOS implementation. 相似文献
