Effects of Manipulative Instruction on Solving Area and Perimeter Problems by Students with Learning Disabilities

Abstract. A multiple baseline design was employed to test the effect of manipulative instruction on the perimeter and area problem‐solving performance of middle and high school students who had been diagnosed with LD in the area of mathematics. Modeling, prompting/guided practice, and independent practice in conjunction with manipulative training were employed to teach both perimeter and area problem‐solving skills. Analysis of data revealed that the students rapidly acquired the problem‐solving‐skills, maintained these skills over a two‐month period, and transferred these skills to a paper and pencil problem‐solving format. This research extends previous findings by revealing that use of concrete manipulatives promotes the long‐term maintenance of skills.

Effects of a Teacher‐Designed and Teacher‐Led Numerical Board Game Intervention: A Randomized Controlled Study with 4‐ to 6‐Year‐Olds

The purpose of the current pilot study was to examine the effects of a teacher‐designed and teacher‐led numerical board game intervention. Fifty‐four 4‐ to 6‐year‐olds were randomly assigned to either the number board game intervention or an active control group. Relative to the control group, children who received the number game intervention demonstrated significant improvements on a numeral identification task. This finding is significant in so far as numeral identification skills play a critical role in more advanced numerical and mathematical reasoning. There was no evidence of training‐related improvements on any of the other tasks. In addition to the intervention effects, the present study provides an example of a successful teacher‐researcher collaboration, providing new insights into the making of bidirectional relations between research and practice.     

Metacognition and Self-Regulation in James,Piaget, and Vygotsky

This article investigates the intertwined constructs of metacognition and self-regulation as they emerge in the works and theories of James, Piaget, and Vygotsky. To coordinate this exploration, we use an interpretive framework based on the relation of subject and object. In this framework, James’s perspective on metacognition and self-regulation is aligned with the Self, Piaget’s with the other and object, and Vygotsky’s with the medium or agency of language. We explore how metacognition and self-regulation function within the realm of human behavior and development as described in the works of each of these theorists. Key questions or issues that emerge for current research are outlined, and the limitations and benefits of each theorist’s perspective vis-à-vis metacognition and self-regulation are discussed.     

Teachers’ perceptions of assessments of their mathematical knowledge in a professional development course

The purpose of the project reported in this article was to evaluate how assessing teachers’ mathematical knowledge within a professional development course impacted from the teachers’ perspective their learning and their experience with the course. The professional development course consisted of a 2-week summer institute and the content focus was geometry. We had decided to assess the mathematical learning of the teachers during this professional development course for various accountability reasons, but were concerned about possible negative by-products of this decision on the teachers and their participation. Thus, we worked to design assessment in ways that we hoped would minimize negative impacts and maintain a supportive learning environment. In addition, we undertook this evaluation to examine the impacts of the assessment, which included homework, quizzes, various projects, and an examination for program evaluation. Seventeen grade 5–9 teachers enrolled in the course participated in the study by completing written reflections and by describing their experiences in interviews. We learned that while our original intent was “to do no harm,” the teachers reported that their learning was enhanced by the assessment. The article concludes by describing the various properties of the assessments that the teachers identified as contributing to their learning of the geometry content, many of which align with current recommendations for assessing and evaluating grade K-16 mathematics students.

Shunning the Bird’s Eye View: General Science in the Schools of Ontario and Quebec

This paper considers the adoption of general science courses in two Canadian provinces, Ontario and Quebec, during the 1930s. In Ontario, a few science teachers had followed the early general science movements in the United States and Britain with interest. During the 1930s, several developments made the cross-disciplinary, applied thrust of general science particularly appealing to Ontario educationists. These developments included a new demand for vocational education, renewed reservations about pedagogical rationales based on transfer of training, and a growing professional divide between high school science teachers and university scientists. Around the same time, scientists in the Quebec’s French-language universities were engaged in a concerted campaign to expand the place of science in the province’s francophone secondary schools. The province’s prestigious classical colleges, which were the scientists’ principal target for reform, privileged an inductive view of science that had little in common with the applied, cross-disciplinary emphasis of the general science courses gaining support in English-speaking school systems. In 1934, however, a popular American general science textbook was adopted in a workers’ cooperative devoted to adult education. Comparing the fate of general science within these two education systems draws attention to the fact that general science made inroads in francophone Quebec but had little influence in public and private schools. In light of the growing support general science enjoyed elsewhere, we are led to explore why general science met with little overt interest by Quebec scientists pushing for school science reform during the 1930s.     

澳门特区免费幼儿教育政策研究

澳门特区自2007～2008学年开始实施15年免费教育,即9年义务教育、3年高中教育和3年学前教育免费.研究者运用网络调查及访谈法,对澳门特区免费幼儿教育政策进行研究,结果发现:(1)免费幼儿教育政策只适用于6家公办幼儿园和42家加入免费教育学校系统的私立幼儿园.(2)7家未加入免费教育学校系统的私立幼儿园需缴学费、补充服务费和选择性服务费,但可获政府发放的学费津贴和书簿费.家长很满意这一政策,并表示愿意继续送孩子上收费的私立幼儿园.(3)受访园(校)长、家长及教师对澳门的免费幼儿教育政策都很满意,教师特别满意政府推出的幼儿园教师津贴.(4)免费幼儿教育政策对私立园所的影响有所不同:有些私立园所为了生存而选择加入免费教育学校系统,有些私立园所则为了校政自主而选择不加入免费教育学校系统.客观上,高收费门槛令不同阶层家庭的幼儿自然分流.
