This study employs narrative methods to give a holistic view of the experiences of five mature age preservice teachers in
a semester unit of science education. The unit was designed to help teachers examine and make explicit their ideas about science
and science teaching and consider ways in which they might put those ideas into practice. The pivotal theme, around which
the teachers' experiences could be organised, was found to be learning science. The preservice teachers expressed a need for
a supportive learning environment in which concepts were built gradually and introduced using concrete examples. Previous
science experience was found to be a major influence on the attitudes the participants brought to the present course. A lack
of previous experience or negative past experiences were a major cause of anxiety. Gender was also important as it had limited
the science experiences available to some participants in the past and continued to influence the way they participated in
classes during the semester.

In an effort to understand the role of interhemispheric transfer in numerical development, we investigated the relationship between children's developing knowledge of numbers and the integrity of their white matter connections between the cerebral hemispheres (the corpus callosum). We used diffusion tensor imaging (DTI) tractography analyses to test the link between the development of the corpus callosum and performance on symbolic and non-symbolic numerical judgment tasks. We were especially interested in the interhemispheric connections of parietal cortex in 6-year-old children, because regions of parietal cortex have been implicated in the development of numerical skills by several prior studies. Our results revealed significant structural differences between children and adults in the fibers of the corpus callosum connecting the left and right parietal lobes. Importantly, these structural differences were predictive of individual differences among children in performance on numerical judgment tasks: children with poor numerical performance relative to their peers exhibited reduced white matter coherence in the fibers passing through the isthmus of the corpus callosum, which connects the parietal hemispheres. 相似文献

Researchers have proposed that the act of postponing academic work may be divided into a traditional definition of procrastination, viewed as maladaptive, and adaptive forms of delay. Adaptive forms of delay may be more consistent with certain facets of self-regulated learning. The current study investigated this issue by examining whether the relations between aspects of self-regulated learning and active delay may be distinct from the relations these aspects of self-regulated learning have with procrastination. Among 206 undergraduates, procrastination was positively predicted by mastery-avoidance goals and negatively by metacognitive strategy usage, whereas active delay was negatively predicted by avoidance goals and positively by self-efficacy. Furthermore, students who reported higher levels of active delay also received better grades. These findings provide support that active delay is a distinct form of delay from procrastination that may be more positive due to its associations with some adaptive self-regulatory processes and academic achievement. 相似文献

Lamaze breathing historically is considered the hallmark of Lamaze preparation for childbirth. This column discusses breathing in the larger context of contemporary Lamaze. Controlled breathing enhances relaxation and decreases perception of pain. It is one of many comfort strategies taught in Lamaze classes. In restricted birthing environments, breathing may be the only nonpharmacological comfort strategy available to women. Conscious breathing and relaxation, especially in combination with a wide variety of comfort strategies, can help women avoid unnecessary medical intervention and have a safe, healthy birth. 相似文献

Part II of “Reclaiming Kindergarten” continues the discussion related to responding to the crisis in today’s kindergarten.
In Part II, two policy questions are posed, the answers to which seek to respond to this continuing crisis. The questions
center on issues related to engaging families in kindergarten and the need to consider a new early childhood paradigm where
kindergarten is part of a continuous and seamless educational experience spanning prekindergarten through third grade. As
in Part I, examples of classroom practice are used to illustrate the effective implementation of these principles in a kindergarten
classroom. 相似文献

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2
classrooms in rural school districts. The research specifically examined changes in (a) teachers’ content knowledge in science;
(b) teachers’ self-efficacy related to teaching science; (c) classroom instructional time allotted to science; and (d) instructional
strategies used in science. The study also investigated contextual factors contributing to or hindering changes in science
instruction. Data sources included a teacher survey, a self-efficacy assessment, content knowledge tests, interviews, and
classroom observations. After one year in the program, teachers showed increased content knowledge and self-efficacy in teaching
science; they spent more instructional time on science and began using different instructional strategies. Key contextual
factors included curricular demands, resources, administrative support, and support from other teachers. 相似文献

The rapid development of ICT (information technology and communication) in the last two decades has changed society substantially as a whole. For higher education institutions, the external environment pressure to incorporate ICT in their educational and administrative processes has forced them to invest in resources for infrastructure and training. In addition, teachers have found that they can use technology in their teaching, but lack of full knowledge of how to use it effectively from a pedagogical point of view. The incorporation of new education modalities depends largely on the contextual variables prevailing in the institution and teachers. In UABC (Autonomous University of Baja California), the early days of online education go hack to 1996, so the study period was from 1996 to 2009. An online survey was designed to fmd out the teachers' backgrounds and involvement in online education, their experience as online teachers, and the tools and practices used. Of 97 teachers who were identified with some experience in online teaching, 70% responded to the Survey (68). It was found that the highest percentage (33%) of teachers who responded the survey started teaching online between 2003 and 2006. 56% of teachers have been teaching between one and five online courses. On the other hand, most teachers recognized that 30%-79% of the content of their courses were online based. The most popular learning management system used is moodle followed by blackboard in teachers' preference. In general, teachers expressed using the three main communication tools of online education: forums, chat and e-mail, favoring the use of e-mail. The communication slrategies teachers often use in their courses promoted student-student and student-teacher interaction. In their evaluation strategies, most said that they used self-assessment, rubrics and to a lesser extent online exams and co-evaluation. The results show that most teachers who have been involved in online education in UABC campus have expressed havi 相似文献

Context-based science courses stimulate students to reconstruct the information presented by connecting to their prior knowledge and experiences. However, students need support. Formative assessments inform both teacher and students about students’ knowledge deficiencies and misconceptions and how students can be supported. Research on formative assessments suggests a positive impact on students’ science achievement, although its success depends on how the formative assessment is implemented in class. The aim of this study was to provide insights into the effects of formative assessments on achievement during a context-based chemistry course on lactic acid. In a classroom action research setting, a pre-test/post-test control group design with switching replications was applied. Student achievement was measured in two pre-tests, two post-tests and a retention test. Participants were Grade 9 students from one secondary school in the Netherlands. Repeated-measures analysis showed a significant effect of formative assessments on students’ achievement. During the implementation of the formative assessments, intriguing discussions emerged between students, between students and teacher, and between teachers. Adding formative assessments to context-based approaches reinforces their strength to meet with the current challenges of chemistry education. Formative assessments affect students’ achievement positively and stimulate feedback between students and teacher(s). 相似文献
