Using a random sample of 389 grade 11 science students, the factor structure of the Longeot test (a measure of logical thinking) is investigated and some psychometric properties of the test items are determined. Varimax rotation on six principal component factors resulted in a simple structure. An attempt is made to interpret the obtained orthogonal factors. Implications of the findings on the “unity hypothesis” of the Piagetian construct of logical thinking and, consequently, on grade 11 science education are discussed. 相似文献

Gifted girls of color represent a potentially untapped resource for increasing and sustaining a diverse science, technology, engineering, and mathematics (STEM) workforce. Girls of color possess unique mathematics and science gifts and talents that can remain unrealized if not addressed before middle school. Culturally responsive STEM out-of-school-time (OST) activities can be an effective means to develop STEM capacity in gifted girls of color. The researchers present three considerations to support the implementation of STEM OST. First, they offer a rationale for culturally relevant STEM enrichment activities for gifted girls of color. Next, the researchers consider how culturally relevant STEM OST activities can help to close the achievement gap. Finally, they explain how professional mentorship opportunities within OST activities can help gifted girls of color navigate the STEM pipeline. 相似文献

Instructional design is not a linear process: designers have to weigh the advantages and disadvantages of alternative solutions,
taking into account different kinds of conflicting and changing constraints. To make sure that they eventually choose the
most optimal one, they have to keep on collecting information, reconsidering continuously whether their own decisions are
still justified in the light of the latest insights. We have studied the role of iteration during instructional design. For
our research, we have used an ISD-based method for the specification of training simulators. During our empirical evaluation
study, we introduced five events that are likely to cause iteration. The results show that the quality of the designs is not
directly related to the amount of iteration. We conclude that there are different kinds of iteration, triggered by different
kinds of actions and events. We propose a list of triggers for iteration some of which originate from outside (new information,
new opinions/arguments and acquisition procedures); others are caused by, or evolve from interaction with the design process
itself (discovery of missing input, need to repair errors, new insights based on work later on in the design process, and
new ideas of the designers).

The study examined whether schools for the deaf were providing services to assist parents in communicating with their children about sexuality (including sexual signs) and whether parents were involved in the sexuality education curriculum within their child's school. The Sexuality Curriculum Questionnaire for Educators of Students Who Are Deaf (Getch & Gabriel, 1998) was completed by 71 educators teaching sexuality curricula in schools for the deaf across the United States. Results indicated that parents were more likely to be involved in approval and development of their children's sexuality education than to receive assistance with sexuality education from the schools. Although the level of parental participation in curriculum development and approval is encouraging, the number of parents actually participating in curriculum development and approval remains low. 相似文献

This paper seeks to question what impact education vouchers have on the process of school choice. The context examined in the paper is the Pre-primary Education Voucher Scheme (‘Voucher Scheme’) introduced in 2007 in Hong Kong. Using a Straussian grounded theory method, data collected from 40 parent interviews are coded, analysed and developed into categories. The paper analytically situates the findings within a model, derived from the data, which is based on two properties: orientation and time. Orientation differentiates and emphasises the significance of choice factors in relation to the school versus the family, and time is related to focus on the present versus the future. The paper subsequently presents the data related to these properties and reflects on the intricate dynamic of parents’ school choice decisions under the Voucher Scheme. 相似文献

Early intervention professionals have implemented natural environment practices for over a decade, despite the continued debate
on how to interpret and implement this practice. This article reviews several theoretical frameworks for understanding natural
environment practice, and also summarizes different approaches for implementation. The authors present a model for rethinking
and redefining natural environment practice in the context of recent approaches. 相似文献

Research Findings: The present study examined associations between children’s classroom interactions and teachers’ perceptions of teacher–child relationships during 1 year of preschool. Teachers (n = 223) reported their perceptions of closeness and conflict in their teacher–child relationships in the fall and spring. Children’s (n = 895) positive classroom interactions with teachers, peers, and learning activities and their negative interactions were observed midyear. Children’s positive interactions with teachers and learning activities predicted teachers’ perceptions of more closeness in the spring when we accounted for fall closeness. Children’s negative interactions predicted teachers’ perceptions of more relational conflict in the spring when we accounted for fall conflict. Children’s positive peer interactions did not predict spring closeness or conflict. Implications regarding teachers’ perceptions of teacher–child relationships and children’s independently observed classroom interactions are discussed. Practice or Policy: Findings provide empirical evidence for an aspect of Pianta, Hamre, and Stuhlman’s (2003) conceptual model of teacher–child relationships. Results indicate that children’s classroom interactions may be a factor related to how teachers report on their relationships with children across 1 year of preschool. Findings point to links between a range of children’s positive and negative interactions during typical instruction and teachers’ relationship perceptions. 相似文献

The present study investigated preservice teachers’ self‐efficacy in classroom management involving students with symptoms of Attention Deficit/Hyperactivity Disorder (ADHD). A total of 137 Chinese preservice teachers were randomly presented with one of four vignettes involving a student character with ADHD symptoms, with manipulations including the character’s gender and diagnostic label of ADHD. Upon reading the vignette, participants responded to questions concerning their self‐efficacy in inclusive classroom management involving the character. Findings based on analysis of covariance indicated an interaction effect of the vignette character’s gender and label on teachers’ self‐efficacy. Specifically, teachers perceived greater self‐efficacy in a classroom involving a girl with an ADHD label than in a classroom involving a girl with no label or a boy with a label. Findings enriched the literature concerning the roles of gender and label in preservice teachers’ self‐efficacy toward inclusive classroom management. 相似文献
