A recursive techniques editor for Prolog

We describe an editor geared to recursive Prolog procedures. It is similar to the structure editors built for many programming languages, except that instead of just ensuring the correctness of the syntax of the procedures built by the editor, the editor also ensures the correct use of recursion. By correct here we mean that the recursive procedure is guaranteed to terminate and to be well-defined. Within these constraints we have tried to ensure that the range of procedures that can be built is as complete as possible.     

Negotiating power and redefining literacy expertise: Buddy Reading in a dual‐immersion programme

This paper reports on a case study of face‐to‐face interaction around and about texts between a second grade dyad in a dual‐immersion programme. Through the lenses of Vygotskian situated cognition and Literacy Studies, classroom observations were conducted, both holistic and focused. Daily peer reading sessions between a dyad were tape recorded, and informal interviews with the teacher and the participating dyad were conducted. The analysis of participants' verbal exchanges revealed multiple pedagogical scaffolds, few of which were unexpected. As meaning making became more salient to the various collaborative literacy tasks, the roles of tutor and tutee were blurred. The shift in power also impacted the direction of language switches. Buddy Reading encouraged the peer readers to acknowledge and draw upon each other's expertise, as they redefined what it meant to be ‘a good reader’.     

Enriching Professional Learning Networks: A Framework for Identification,Reflection, and Intention

Many educators in the 21st century utilize social media platforms to enrich professional learning networks (PLNs). PLNs are uniquely personalized networks that can support participatory and continuous learning. Social media services can mediate professional engagements with a wide variety of people, spaces and tools that might not otherwise be available. Teachers who once might have had access to only a handful of colleagues can now employ Facebook, Twitter and other mediums to learn from peers across the globe at any time. However, educators face numerous challenges building and enhancing their PLNs for professional growth. To support educators in the development of their PLNs, we present a framework for PLN enrichment. Rooted in our research and experiences with PLNs, this flexible framework is designed to help educators reflect upon how they might continuously improve their PLN experiences and outcomes.     

Disruptive Behaviour in School,Personality Characteristics and Heart Rate (HR) Levels in 7‐ to 9‐year‐old Boys

Disruptive behaviour, as assessed by teachers, is reported as being consistently related to low base heart rates and low reactivity to mild stress. To date, most investigations have used mainstream school samples of boys within the 11‐16 age range approximately. It has been suggested that the predicted low base heart rates for antisocial children may be reversed in younger children. Present findings do not confirm such a trend in boys aged 7 to 9 years. Their responses were similar to those of older children. The implications for further research and the management of children in school are discussed.     

AN EXPERIENTIALLY‐BASED TRAINING PROGRAMME IN CIVIL ENGINEERING

An innovative training programme providing second year students with a real taste of civil engineering practice through the construction of full‐size structures was introduced at the Nanyang Technological Institute, Singapore. Students are divided into companies, each responsible for executing the construction project for a profit, and in accordance with contract requirements in the forms of specifications and design drawings. Each company is sub‐divided into management, office and field groups. Thus the students, through a mandatory rotation of the role play, gain valuable experience in the field, office and management functions through personal involvement in such a real‐life project. To reflect the objectives of the programme, a system of assessment was developed based on the student performance at the team, group and individual levels. Due to the short history of the programme and since a true test of the effectiveness of this type of training is through the performance of the graduates, a summative evaluation is difficult to make at the present time. However, some interim feedback from the students, staff members and industrialists on students’ performance subsequent to their second year course work suggest that the programme has served well in achieving its intended objectives.     

Implementing microcomputers in science teaching

Conclusion The most important finding from this study is that if one adheres to the guidelines from the literature on staff development and educational change, teachers can and will change their teaching behaviors. It is very easy, however, to underestimate the time and resources required to implement change in schools. Even a seemingly simple change such as increasing use of educational computing, which teachers can implement in their individual classrooms without an overhaul of schools, is immensely complex and difficult. Helping teachers and schools change requires a systematic effort, with intensive on-going support over a period of three or more years. Science educators, school leaders, and the public must learn that school improvement is not an event but a continual process of renewal and refinement. This study demonstrates the importance of allocating resources to staff development and implementation along with those for curriculum development. Fortunately, the National Science Foundation has recognized the importance of implementation in school improvement by requiring that implementation be an integral part of all curriculum development projects it funds. As Hall (1986) said, “It is not enough to build pretty boxes; what is important is to get the boxes used.” This article is based on work supported by the National Science Foundation under Grant No. MDR-8470061. Any opionions, findings, and conclusions or recommendations expressed in this publication are those of the authors and do not necessarily reflect the views of the National Science Foundation.     

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.     

Developing an empirically based typology of attitudes of entering students toward participation in learning communities

Learning communities (LC) seek to strengthen and enrich students’ connections to each other, their teachers, and the subject matter they are studying. Their success depends on the nature of the learning community program, the learning styles of the students who participate and the reasons why students entered the program. This study uses a combination of factor and cluster analysis to develop a typology of student experiences that is used to examine the efficacy of the Learning Community program at Temple University, Philadelphia. The findings identify distinctive types of learning community experience and show that not all types match well with all students. The study questions the common assumption that learning communities are always helpful to student learning and development, and cautions against the belief that benefits will inevitably accrue. The variation in the value and impact on students of this long‐standing learning community program suggests that the evaluative burden of proof is for administrators to clearly demonstrate and not assume a uniformly positive impact of learning communities.     

Does early reading failure decrease children's reading motivation?

The authors used a pretest-posttest control group design with random assignment to evaluate whether early reading failure decreases children's motivation to practice reading. First, they investigated whether 60 first-grade children would report substantially different levels of interest in reading as a function of their relative success or failure in learning to read. Second, they evaluated whether increasing the word reading ability of 15 at-risk children would lead to gains in their motivation to read. Multivariate analyses of variance suggest marked differences in both motivation and reading practice between skilled and unskilled readers. However, bolstering at-risk children's word reading ability did not yield evidence of a causal relationship between early reading failure and decreased motivation to engage in reading activities. Instead, hierarchical regression analyses indicate a covarying relationship among early reading failure, poor motivation, and avoidance of reading.
