GTravels towards Problem Based Learning in Medical Education (VPBL)

This paper reports the results and insights ofan exploratory investigation of theeffectiveness of a prototypic virtualproblem-based learning (VPBL) exercisedelivered via the WWW, that uses HypermediaAssisted Instructional Technologies (HAIT). The study targeted all first year medicalstudents at a south-central University Schoolof Medicine who were enrolled in the humanphysiology course during the Spring 2000 (n =150). A quasi-experimental, post-test onlyresearch design compared the VPBL and atext-based version of the same PBL exercise onstudents' achievement, as measured by a set ofselected physiology examination items, andtheir perceptions of the learning environment,as measured by the Teaching and LearningEnvironment Questionnaire (TLEQ) (Chauvin &Bowdish, 1998). Findings suggest that the VPBLis equally as effective as the text-basedversion for enhancing students' learning andtheir learning environment in small group, PBLsessions. In this paper, we examine theevidence supporting the VPBL innovation andexplore what constitutes necessary andsufficient evidence that an educationalinnovation should be incorporated appropriatelyinto the medical educational practice of aschool. We examine instructional design issuessuch as learner control, instructional control,and teacher and learner roles as related toinstructional development for the WWW, bycomparing and contrasting our observations ofthe VPBL design experiment with theprofessional literature.     

Science education and affect

Thought experiments are tools often used by physicists. Learning authentic physics then also means that students need to develop a familiarity with the reasoning processes of thought experiments. This study examines the nature of learning processes that involve communication about image‐based micro‐worlds in optics. The results of this study show that students’ investigations often have the structure of thought experiments. Thought experiments that use computer‐based microworlds are powerful because they capitalize on the human capability for imagery that allow learners to ‘see’ the physical processes and construct qualitative understandings. In this study, the structure of students’ activities as thought experiments arose from their collective efforts which started with the construction of an optics simulation. In the course of the activities, students’ understanding evolved from fragmented views of optical situations to system views that included multiple components. Collaborative thought experiments are therefore emergent phenomena, triggered by the events as a whole rather than being pre‐designed. In the course of the activities, students who participated in collective problem solving gradually adopted shared graphical representations and meanings.     

The Complementary roles of the Headteacher,the Mentor and the Advisory Teacher in Induction and School‐based Teacher Training

This article reports on the findings of a two year research project on the management of new teacher induction in five LEAs (Turner, 1992). Headteachers, mentors and newly qualified teachers in twelve schools were interviewed as were LEA officers, Inspectors and advisory teachers. The analysis showed the key roles of headteacher, mentor and advisory teacher to be different but complementary. The conclusions are drawn from a detailed analysis of some 180 interviews.     

Sustainable Procurement: Integrating Classroom Learning with University Sustainability Programs

Organizations are facing increased pressure from various stakeholders to address issues of sustainability, resulting in a growing demand for sustainability education and training. Procurement groups remain the key drivers of many sustainability‐related strategies, placing pressure on universities to integrate sustainability concepts into the business curriculum. This article describes a replicable educational model that allows students to learn about sustainable procurement while concurrently promoting sustainability within the university community.     

Evaluating a Classroom Multimedia Programme in the Teaching of Literacy

This paper explores classroom interventions using a particular form of multimedia ICT, and looks to study pupil learning gains which accrue from its use. Work within the Literacy Hour in eight schools was detailed in order to evaluate the effectiveness of this communication system and the research data include pre- and post-test assessments, along with interviews with classroom teachers and pupils. The children are presented with a series of journalistic tasks and classroom activities which they resolve through the use of a compact and coordinated information system. The outcomes demonstrate that children can become self-directive and very active, exploratory, learners in a very short period of time. They quickly enjoy the freedom and control which the system permits, and through which they can be shown to enhance particular literacy skills. The lessons to be learned here relate to the management and organisation of classroom teaching in the face of systems which promote rapid devolution of learning to the learner.     

The Politically and Culturally One-Sided Campus: Causes, Consequences, Remedies: Pernicious Politicization in Academe: Victims of the One-Sided Campus: Advocacy in the College Classroom

The three papers that follow were delivered on 22 April 2006 at a conference of the California Association of Scholars at the Annenberg School on the campus of the University of Southern California in Los Angeles. The aim of the panelists was to diagnose the political and cultural imbalance in higher education, to analyze its causes and consequences, and to look for remedies. Other essays from that conference may appear later in AQ.     

Implementing Restricted Maximum Likelihood Estimation in Structural Equation Models

Structural equation modeling (SEM) is now a generic modeling framework for many multivariate techniques applied in the social and behavioral sciences. Many statistical models can be considered either as special cases of SEM or as part of the latent variable modeling framework. One popular extension is the use of SEM to conduct linear mixed-effects modeling (LMM) such as cross-sectional multilevel modeling and latent growth modeling. It is well known that LMM can be formulated as structural equation models. However, one main difference between the implementations in SEM and LMM is that maximum likelihood (ML) estimation is usually used in SEM, whereas restricted (or residual) maximum likelihood (REML) estimation is the default method in most LMM packages. This article shows how REML estimation can be implemented in SEM. Two empirical examples on latent growth model and meta-analysis are used to illustrate the procedures implemented in OpenMx. Issues related to implementing REML in SEM are discussed.     

Comparing Models of Nature of Science Dimensionality Based on the Next Generation Science Standards

Instruments measuring understanding of the nature of science (NOS) are required if educational institutions intend to use benchmarks or examine the effects of interventions targeting students’ NOS development. Compared to other constructs, NOS understanding is complex, having been the subject of debate among scholars in both its substance and its dimensionality. This complexity invites challenges in defining what is to be measured. Drawing from the perspective that policy reform documents provide pragmatic consensus-based definitions of NOS, this study investigated how well the dimensionality described in the NOS component of the Next Generation Science Standards (NGSS) framework matched the empirical structure of data collected from a set of secondary-school students’ responses to an NOS instrument comprising multiple-choice and Likert-scale items. Using multidimensional item response modeling to compare structures of NOS dimensionality, we found that treating NOS as comprising multiple dimensions—as defined by the themes in the NGSS NOS framework—resulted in a better fitting model than when treating NOS as a single dimension. The multidimensional model also had fewer poorly functioning items and revealed NOS profiles that otherwise would have been masked in a model treating NOS as a single dimension. These results provide support for the NOS NGSS framework and contribute to the ongoing discussion about the dimensionality of NOS.     

A different view of literacy

The Equals Formal Curriculum English Scheme of Work has been designed for that very small percentage of the school population, perhaps as low as one or two per cent, who have global learning difficulties (GLD) to such a degree that they are consistently working at levels significantly below their age-related peers for all of their academic lives. The term GLD includes all those in England currently ascribed as having severe learning difficulties (SLD) and many if not most, currently ascribed as having moderate learning difficulties (MLD). Evidence of the difficulties faced by such pupils will become increasingly obvious beyond Year 1 at age 6, because the difficulties are global rather than specific. That is, they are likely to affect all learning, but will be particularly apparent in numeracy and literacy. This paper, the first of two, seeks to clarify why reading and writing are so extraordinarily difficult for this population and posits that the answers lie in challenging perceived wisdoms within the education system’s predilections towards (i) regarding phonics as the only solution to reading difficulties (ii) persisting over time (and in the face of evidence to the contrary) with the view that children, young people and adults with GLD can make sufficient progress within phonics teaching and (iii) the use of differentiation of a standardised national curriculum model as being a sufficient answer to global learning difficulties. Clearly the main language used in England is English, but the principles and ideas outlined in this paper should apply in any language which uses a phonic structure when teaching language.
