Nativist and constructivist approaches to the study of development share a common emphasis on characterizing beginning and end states in development. This focus has highlighted the question of preservation and transformation—whether core aspects of the adult end state are present in the earliest manifestations during infancy. In contrast, a developmental systems approach emphasizes the process of developmental change. This perspective eschews the notions of objective starting and ending points in a developmental progression and rejects the idea that any particular factor should enjoy a privileged status in explaining developmental change. Using examples from motor development and animal behavior, we show how a developmental systems framework can avoid the pitfalls of the long and contentious debate about continuity versus qualitative change. 相似文献
Childcare within Australia has undergone significant reform as a result of the implementation of the nationally mandated Belonging, Being and Becoming: The Early Years Learning Framework [EYLF] (Department for Education, Employment and Workplace Relations [DEEWR]. 2009. Belonging, Being and Becoming. The Early Years Learning Framework for Australia. Canberra: Australian Government Department of Education, Employment and Workplace Relations). The EYLF articulates contemporary perspectives of the child through its principles, practices and learning outcomes. Educators are required to promote these principles, practices and learning outcomes with children aged from birth to 5 years. This paper reports the findings from a research project that sought to investigate how educators applied their understanding of learning outcome two of the EYLF (children are connected with and contribute to their world). The focus of this research was educators working with children aged two to three years within childcare centres operating on school sites, in metropolitan Western Australian. The research design was qualitative and situated within the interpretivist paradigm. Observations were used as the method for gathering data and these were analysed through a process of coding. This paper presents the observational findings of educators’ practices within learning outcome two. Composite vignettes from the voice of the child are included to present the observational findings. In centralising the voice of the child, contemporary perspectives are made explicit. 相似文献
In 5 investigations we examined a new procedure for assessing children's understanding that messages arise from speakers' internal representations. 3- and 4-year-olds watched the enactment of a message-desire discrepant story in which a speaker doll, who believed wrongly that bag A was in location 1 and that bag B was in location 2, gave a message referring to the bag in location 1. In a message-desire consistent control condition, the speaker had a correct belief about the bags' locations. Children frequently judged correctly in the discrepant story that the speaker (who specified location 1) wanted the bag in location 2, and judged correctly in the consistent story that the speaker wanted the bag in location 1. That is, young children attended to the speaker's internal representations, and not just the real-world referent of the message, when judging what the speaker wanted. In one of the investigations, children performed better on the message-desire discrepant task than on a false belief task. We discuss why they might find it particularly easy to take into account false belief when inferring desire on the basis of behavior. 相似文献
Bellman's dynamic programming equation for the optimal index and control law for stochastic control problems is a parabolic or elliptic partial differential equation frequently defined in an unbounded domain. Existing methods of solution require bounded domain approximations, the application of singular perturbation techniques or Monte Carlo simulation procedures.In this paper, using the fact that Poisson impulse noise tends to a Gaussian process under certain limiting conditions, a method which achieves an arbitrarily good approximate solution to the stochastic control problem is given. The method uses the two iterative techniques of successive approximation and quasi-linearization and is inherently more efficient than existing methods of solution. 相似文献
Girls’ attitudes towards mathematics can impact their achievement and career choices in STEM fields. Can the introduction of inquiry-based learning (IBL) in mathematics classes generate positive associations between girls’ perceptions of the learning environment and their attitudes towards mathematics? Based in the United Arab Emirates, this study provided important information about the relationships between learning environment factors central to an inquiry method and student engagement. Data collection involved administering two surveys to female mathematics students (N?=?291) in four schools: one to assess students’ perceptions of the learning environment and another to assess students’ attitudes towards mathematics. Positive and statistically-significant (p?<?.01) associations emerged between learning environment factors important to an inquiry approach and students’ attitudes. These findings provide important information about how IBL might improve girls’ attitudes towards mathematics classes and whether IBL environments are related to their attitudes.
Among contemporary means of enhancing student learning, formative assessment is perhaps one of the most important and effective. While formative assessment ideas and practices have been shown to have a proven record enhancing student learning, these practices are slow to be fully integrated into teachers’ day-to-day classroom practices. This study describes a collaborative effort among university faculty and public school partners to train teachers in the skills and practices of formative assessment. Regarding teachers’ involvement in the formative assessment professional development, findings highlight that 1) teachers’ participation in the professional development efforts did strengthen their understanding of both general knowledge of formative assessment and the use of formative assessment practices, 2) teachers’ plans to use the strategies in the future were related to their understanding of these strategies, and 3) in-depth and comprehensive understanding of formative assessment practices were critical to concrete applications of such practices in their classrooms. With respect to the impact on student learning, an overall effect size of .41 was found for teachers who utilized a formative assessment strategy compared with district averages for similar learning objectives when the practices were not used. 相似文献
This study investigated whether children's inversion shortcut use (i.e., reasoning that no calculations are required for the problem 4 × 8 ÷ 8, as the answer is the first number) is related to their analogical reasoning ability, short-term memory capacity, and working memory capacity. Children from Grades 6 and 8 solved multiplication and division inversion problems and classical analogy word problems and completed memory tasks. Analogical reasoning ability and working memory functioning both accounted for individual variance in inversion shortcut use. These findings suggest that the ability to understand relationships and executive functioning may enable children to internally represent and manipulate mathematical problems, facilitating the application of conceptual mathematical knowledge to generate the inversion shortcut. 相似文献
In the literature, little research has hitherto been conducted to examine the implementation of integrated speaking test tasks.
This study, in response, set out to compare the anxiety induced by a reading-to-speak task and the anxiety produced by a speaking-only
task and to explore students’ experiences of taking the reading-to-speak task. Forty-seven Taiwanese EFL learners completed
a reading-to-speak task and a speaking-only task, filled out a state anxiety inventory twice, and responded to an open-ended
questionnaire. The paired t-test revealed that the reading-to-speak task produced a statistically comparable degree of anxiety as the speaking-only task,
possibly owing to the additional anxiety inflicted by its reading component. The qualitative analysis disclosed that students
preferred the reading-to-speak task to the speaking-only task, even though it provoked additional anxiety, featured additional
challenges, and entailed different response strategies. In light of these findings, implications are proposed for oral assessment
research and EFL oral assessment practices. 相似文献
