Exploring Conceptual Integration in Student Thinking: Evidence from a case study

Two reasons are suggested for studying the degree of conceptual integration in student thinking. The linking of new material to existing knowledge is an important aspect of meaningful learning. It is also argued that conceptual coherence is a characteristic of scientific knowledge and a criterion used in evaluating new theories. Appreciating this ‘scientific value’ should be one objective when students learn about the nature of science. These considerations imply that students should not only learn individual scientific models and principles, but should be taught to see how they are linked together. The present paper describes the use of an interview protocol designed to explore conceptual integration across two college‐level subjects (chemistry and physics). The novelty here is that a single interview is used to elicit explanations of a wide range of phenomena. The potential of this approach is demonstrated through an account of one student's scientific thinking, showing both how she applied fundamental ideas widely, and also where conceptual integration was lacking. The value and limitations of using this type of interview as one means for researching conceptual integration in students' thinking are discussed.     

Students’ Conceptions of Ionisation Energy: A Cross‐cultural Study

Previous studies have indicated that A‐level students in the UK and Singapore have difficulty learning the topic of ionisation energy. A two‐tier multiple‐choice instrument developed in Singapore in an earlier study, the Ionisation Energy Diagnostic Instrument, was administered to A‐level students in the UK, advanced placement high school students in the USA, and first‐year university students in China, New Zealand, and Spain to determine whether the students from different countries and educational systems had similar conceptions and difficulties as the students in Singapore with the concepts assessed in the instrument. The results showed that, in general, the students in all six samples had similar alternative conceptions, which were grouped under the categories of octet rule framework, stable fully‐filled and half‐filled subshell conceptions, and conservation of force thinking. The students also resorted to relation‐based thinking when answering items involving the trend of ionisation energies across Period 3. Implications for teaching and further research are discussed.     

Strategies for improving communication between teachers and school students about learning: a university/school collaborative research project

The research reported here is the result of a collaborative project between a group of teachers in a secondary school and two university lecturers. The group has been meeting for several years and the issue of trying to improve communication arose as a result of findings from a previous study in the school. After reviewing the literature, we were able to identify actions for teachers to trial in the school and, following data collection and analysis, we were able to refine those actions for widespread adoption in the school. We were also able to identify issues that required further exploration. The research exemplifies a way in which university and school staff can engage in collaborative, high quality research. It also identifies some of the complexities involved for schools and teachers as they try to improve practice.     

The Impact of Relational Characteristics and Reasons for Topic Avoidance on Relational Closeness

Although research suggests that the act of topic avoidance itself has consequences for romantic partners, it seems equally likely that the antecedent conditions underlying these decisions to avoid certain topics also lead to important relational outcomes. Framed by communication boundary management theory, relationship characteristics, motivation for topic avoidance, and implications for relational closeness were examined. Findings indicate that relational commitment characteristics and individuals' reported rationale for topic avoidance are related to perceptions of relational closeness. These results illustrate the importance of understanding the underlying factors that motivate the decision to engage in topic avoidance and their impact on romantic relationships.     

Secondary School Students’ Epistemic Insight into the Relationships Between Science and Religion—A Preliminary Enquiry

A number of previous studies have shown that there is a widespread view among young people that science and religion are opposed. In this paper, we suggest that it requires a significant level of what can be termed “epistemic insight” to access the idea that some people see science and religion as compatible while others do not. To explore this further, we draw on previous work to devise a methodology to discover students’ thinking about apparent contradictions between scientific and religious explanations of the origins of the universe. In our discussion of the findings, we highlight that students’ epistemic insight in this context does seem in many cases to be limited and we outline some of the issues emerging from the study that seem to boost or limit students’ progress in this area.     

A Theoretical and Empirical Exploration of Intrinsic Problems in Designing Inquiry Activities

A central concern in science education is promoting inquiry activities, and a significant amount of research in science education has addressed what inhibits this goal. However, this research has tended to be focused on implementation issues. Levels of implementation are correlated with extrinsic barriers such as time, resources and teacher knowledge, but the internal structure of inquiry remains unexamined. However, are there also some ways in which inquiry based instruction is intrinsically difficult? That is, given perfect conditions for implementation, is devising inquiry activities a non-trivial matter, and are there patterns to the difficulties in doing so? The aim of this paper is to provide both a theoretical and empirical basis for the intrinsic problems associated with the construction of inquiry activities. We present a theoretical framework that connects contemporary studies of science to the classroom context. We then examine a case study of teacher education students designing inquiry-based instruction to demonstrate empirical evidence of intrinsic problems. Our ultimate goal is to improve our ability as teacher educators to guide science teachers in fulfilling this central task of their work.     

School drop out in Bangladesh: Insights using panel data

This paper examines the relative strength of different factors associated with school drop out using data collected between 2007 and 2009 in Bangladesh. A sample of 9046 children, aged 4–15, was selected across six districts for a household survey focusing on children's school access and experiences. Two groups of children were identified: those who were enrolled in school in both 2007 and 2009 and those who dropped out by 2009. Using a multivariate logit model, results show age and gender, together with financial constraints, such as lack of income and school expenditure, as the top predictors of school drop out. Two other important predictors are lack of parental support for children's school work and school absenteeism. This paper identifies some possible interventions that could reduce school drop out. These include campaigns to reduce late entry and overage enrolment, reductions in direct costs of schooling, and more support for low achieving children to compensate for lack of educational support at home.     

Cost Analysis of a Distance Education MSW Program

The use of technology to facilitate education and the provision of an entire higher education degree has exploded in the last two decades. Social work educators have been a part of that trend and have started to utilize distance education (DE) technologies. There is a growing literature regarding the efficacy of DE instruction in social work, and scholars are actively developing best practices. However, there is little research in general to support the cost of DE, no cost studies in social work, and none comparing costs of DE delivery to costs associated with a face-to-face program. This study hopes to fill this gap by providing an analysis of the direct costs of an MSW DE program in comparison to similar costs of a face-to-face program.     

Using the Repertory Grid as a Complementary Probe in Eliciting Student Understanding and Attitudes towards Science

Abstract

In previous research, participation in science studies in senior secondary school has been related to both background characteristics of students and to earlier achievements and interests. This paper reports an investigation of participation in combinations of subjects in senior secondary schools in Australia which embody different science orientations. It shows that different combinations of factors shape participation in physical science’ and ‘biological and other science’ types of course. Both are favoured by investigative interest but participation in a physical science course type is strongly associated with high levels of earlier school achievement in numeracy and gender whereas participation in a biological and other science course type is more strongly associated with social background and curriculum influences. In addition the paper suggests that the low participation by females in physical science courses should be interpreted in terms of an interactive influence of gender, earlier achievement and socio‐economic background.     

Gender Differences in Science Preferences on Starting Secondary School

Pupils in their first weeks of secondary school were asked to select from a list those topics they would be interested in studying in science. Gender differences were found supporting the pattern previously reported in the literature: in particular that boys predominantly selected topics with a mechanical connection, whilst girls predominantly selected topics related to human biology.
