College chemistry and piaget: The relationship of aptitude and achievement measures

Cognitive performance on “An Inventory of Piaget's Developmental Tasks” (IPDT) was related to the Scholastic Aptitude Tests and performance in both college chemistry lecture and laboratory classes. The IPDT is a valid and reliable 72-item, untimed, multiple-choice paper-and-pencil inventory. It has 18 subtests grouped into five problem areas representing different Piagetian tasks. Subjects (n = 225) from two different levels of introductory chemistry courses participated. IPDT scores were significantly correlated with SAT and placement data. In overall Piagetian development, “A” students rated higher than others. Performance in classification and proportional reasoning problem areas correlated with course achievement, particularly for higher-level students. Weakest areas of development were indicated by subtest scores and are described with implications for course performance. Finally, Piagetian tasks were related to learning and instructional activities in introductory chemistry classes and are discussed.     

Inclusive educational leadership to establish a co-operative school cluster trust? Exploring perspectives and making links with leadership for learning

ABSTRACT

One remarkable feature of the contemporary school landscape in England is the number of schools that have chosen the co-operative framework to shape their work and relationships. When a group of schools decides to become a co-operative trust, leadership challenges arise both in the process of establishing an inclusive collaborative cluster and in living out co-operative values. To add to the limited literature on co-operative school leadership, a study in a school cluster trust explored headteachers’, governors’ and teachers’ perspectives and beliefs through interviews, group discussions and questionnaires. These data sources revealed some of the motivations for, benefits of, and strategies to support inter-school collaboration guided by the co-operative values of democracy, solidarity, equality, equity, self-help and self-responsibility. Importantly, a range of perspectives on the extent to which leadership was viewed as, and appeared to be, an inclusive practice undertaken by all members of the cluster was identified. A particular contribution of this work is that it exemplifies resonances between the values and principles of the co-operative movement and those of the Leadership for Learning framework. Since these two models are being increasingly adopted and integrated into a variety of educational settings, the research findings may inform leadership practice more widely.     

Peer versus staff tutoring in problem-based learning

Effects of student versus staff tutoring on student learning in a problem-based, health sciences curriculum were studied. Academic achievement of 334 tutorial groups guided by staff tutors was compared with achievement of 400 groups guided by student tutors. In addition, students rated their tutor's performance on four behaviors considered critical to facilitating student learning. Overall, students guided by a staff tutor achieved somewhat better. In terms of practical significance, the difference was, however, fairly small. Staff tutors were rated as more knowledgeable and their contributions as more relevant. In addition, they asked stimulating questions to a larger extent. However, an interaction effect was found between the ratings and the year of study: Peer tutors displayed the supportive behaviors more extensively in the first year, whereas staff tutors' ratings were higher as the curriculum advanced. These results were interpreted in terms of the cognitive congruence framework.Parts of this article have been presented to the Annual Meeting of the American Educational Research Association, Atlanta, GA, April, 1993.     

Public Identity and Collective Memory in U.S. Iconic Photography: The Image of "Accidental Napalm"

Thirty years after the fact, the Vietnam War continues to haunt the collective memory of the United States. One of the primary embodiments of that haunting is the image of a naked girl running down a road toward the camera, screaming in pain and terror from the napalm burns on her back and arms. The photograph, often dubbed “accidental napalm,” provides a complex construction of viewer response that was uniquely suited to the conditions of representation in the Vietnam era, while it reflects a continuing struggle within public culture since that time. In this essay, we offer a close reading of the photograph as a performance of public judgment, and we explore its subsequent history of appropriation. We argue that the photograph functions as a powerful emotional and inventional resource for animating moral deliberation and democratic dissent as it mediates the “stranger relationality” central to public engagement. At the same time, the image also motivates dominant narrative responses that reinscribe liberal ideology to inhibit collective memory and public accountability. This ambivalence in the circulation of the iconic image is grounded in fundamental affinities between photographic representation, public culture, and mass media.     

The effectiveness of simulated robots for supporting the learning of introductory programming: a multi-case case study

This work investigates the effectiveness of simulated robots as tools to support the learning of programming. After the completion of a systematic review and exploratory research, a multi-case case study was undertaken. A simulator, named Kebot, was developed and used to run four 10-hour programming workshops. Twenty-three student participants (aged 16–18) in addition to 23 pre-service, and 3 in-service, teachers took part. The effectiveness of this intervention was determined by considering opinions, attitudes, and motivation as well as by analysing students’ programming performance. Pre- and post-questionnaires, in- and post-workshop exercises, and interviews were used. Participants enjoyed learning using the simulator and believed the approach to be valuable and engaging. The performance of students indicates that the simulator aids learning as most completed tasks to a satisfactory standard. Evidence suggests robot simulators can offer an effective means of introducing programming. Recommendations to support the development of other simulators are provided.     

Beyond ‘Managed Change’: Rethinking How Schools Improve 1

The following paper argues that existing model of change management in education are more appropriate for understanding small scale innovations than larger reforms. Results from two studies of schools engaged in major transformations are used to illustrate some of the differences between previous and current findings. A model of organizational learning as an alternative is presented, and some implications for both practice and theory in school improvement are discussed.
