Teachers’ beliefs about inquiry-based learning and its impact on formative assessment practice

ABSTRACT

Background

Inquiry pedagogy has been advocated as means to engage and motivate students to learn science. The development of teacher formative assessment practice in inquiry is key for a successful implementation of student-centred inquiry pedagogy in the classroom.     

Reflections on knowledge management from a critical systems perspective

This paper considers some significant aspects of knowledge management (KM) from a critical systems thinking (CST) point of view. CST prides itself on theoretical awareness and methodological sophistication, and these are the traits brought to bear in analysing the organisational models and well-known concepts used in KM. The results call into question the idea that the Japanese version of KM is best seen as resting upon an organic model and the notion that the Eastern tradition of thought has a monopoly on recognising the significance of tacit knowledge. The need for a prolonged dialectical debate between KM and CST is established.     

Assessing the relative performance of U.K. university technology transfer offices: parametric and non-parametric evidence

We present evidence on the relative performance of U.K. university technology transfer offices (TTOs) using data envelopment analysis (DEA) and stochastic frontier estimation (SFE). U.K. TTOs are found to exhibit low-levels of absolute efficiency. There also appear to be decreasing returns to scale, implying that TTOs may need to be reconfigured into smaller units. The development of regionally-based sector focused TTOs is also advised. Consistent with qualitative evidence from U.S. TTOs, we find that there is a need to upgrade the business skills and capabilities of U.K. TTO managers and licensing officers.     

Mitigation of Blast Effects on Aluminum Foam Protected Masonry Walls

Terrorist attacks using improvised explosive devices (IED) can result in unreinforced ma-sonry (URM) wall collapse. Protecting URM wall from IED attack is very complicated. An effective solution to mitigate blast effects on URM wall is to retrofit URM walls with metallic foam sheets to absorb blast energy. However, mitigation of blast effects on metallic foam protected URM walls is currently in their infancy in the world. In this paper, numerical models are used to simulate the per-formance of aluminum foam protected URM walls subjected to blast loads. A distinctive model, in which mortar and brick units of masonry are discritized individually, is used to model the perform-ance of masonry and the contact between the masonry and steel face-sheet of aluminum foam is modelled using the interface element model. The aluminum foam is modelled by a nonlinear elas-toplastic material model. The material models for masonry, aluminum foam and interface are then coded into a finite element program LS-DYNA3D to perform the numerical calculations of response and damage of aluminum foam protected URM walls under airblast loads. Discussion is made on the effectiveness of the aluminum foam protected system for URM wall against blast loads.     

Problem solving and classical genetics: Successful versus unsuccessful performance

Expert-novice problem-solving research is extended in this study to include classical genetics. Eleven undergraduates (novices) and nine graduate students and instructors (experts) were videotaped as they solved moderately complex genetics problems. Detailed analysis of these “think aloud” protocols resulted in 32 common tendencies that could be used to differentiate between successful and unsuccessful problem solvers. Experts perceive a problem as a task requiring analysis and reasoning and they tend to use a knowledge-development (forward-working) approach. They make frequent checks on the correctness of their work, use accurate and detailed bookkeeping procedures, and have a broader range of heuristics to apply to the problem. It is clear that studying problem solving using the expert/novice design requires that the problems be difficult enough to require more than more recall and yet simple enough to allow novices a chance for solution. Applying elementary probability concepts seemed to be the most difficult aspect of many of the genetics problems, even for the experts.     

Teachers developing assessment for learning: impact on student achievement

While it is generally acknowledged that increased use of formative assessment (or assessment for learning) leads to higher quality learning, it is often claimed that the pressure in schools to improve the results achieved by students in externally‐set tests and examinations precludes its use. This paper reports on the achievement of secondary school students who worked in classrooms where teachers made time to develop formative assessment strategies. A total of 24 teachers (2 science and 2 mathematics teachers, in each of six schools in two LEAs) were supported over a six‐month period in exploring and planning their approach to formative assessment, and then, beginning in September 1999, the teachers put these plans into action with selected classes. In order to compute effect sizes, a measure of prior attainment and at least one comparison group was established for each class (typically either an equivalent class taught in the previous year by the same teacher, or a parallel class taught by another teacher). The mean effect size in favour of the intervention was 0.32.     

The degree to which students and teachers are involved in second-level school processes and participation in decision-making: an Irish Case Study

The Education Act (1998 Education Act. 1998. Dublin: Government Publications. [Google Scholar]) is a key policy document in Irish education, emphasising the rights, roles and responsibilities of key stakeholders, including parents, teachers and pupils in schools. Since 1998 the Department of Education and Skills (DES) has stressed the need to introduce an increased role for teachers and pupils in decision-making. It is therefore timely to explore the response of teachers and students to such a collaborative school environment in a rural second-level school of approximately 600 students. Transition year (TY) students (ages about 15–16) and their teachers were surveyed by questionnaire and interviewed. It finds that while the school is proactive in involving students and teachers in decision-making, a source of social, personal and professional empowerment, experienced teachers, and students in particular, want a more substantial voice. For example, most students want more say. They want class discussions or a vote, not just Student Council (SC) representation, on important and not just trivial issues. They want involvement before decisions are taken, with more feedback. Overall, participation is considered important by all stakeholders.
