Learners' Approaches to Solving Mathematical Tasks: Does Specialisation Matter?

This article emerged from an analysis of learners’ responses to a task presented to learners studying Mathematics and Mathematical Literacy (ML) in Gauteng, South Africa. Officially, Mathematics and ML are two separate learning areas. Learners from Grade 10 onwards are supposed to take either one or the other, but not both. This means that by Grade 11, learners would have acquired different kinds of knowledge and problem solving skills depending on which of these they take. The article demonstrates that this possibility may not necessarily happen. Grade 11 learners from both learning areas appeared to have acquired sufficient knowledge and skills and were able to solve similar Mathematics tasks in similar ways, with similar adequacy. We argue that, contrary to common perceptions in the field of Mathematics education (particularly in South Africa), engaging in ML does not and should not make one less mathematically advanced than engagement in pure Mathematics.     

Public and private higher education institutions in Serbia: Legal regulations,current status and opinion survey

This article provides insight into the state of higher education in Serbia, particularly in the context of reform processes based on European Higher Education Area principles. A multidimensional approach was taken, encompassing (a) a review and analysis of legal regulations relevant to the historical context of Serbia, (b) an examination of current working conditions at accredited state and private higher education institutions, (c) and a pilot survey of attitudes among the main participants in higher education teaching. The research gauged attitudes of university professors and students with work or study experiences, respectively, at both state and private higher education institutions. Specific instruments for measuring attitudes were constructed for this study. Professors' attitudes toward state and private higher education were compared through the assessment of aspects of organisational culture including work organisation, stimulating atmosphere, innovation, and creativity. Students expressed their attitudes toward state and private higher education in terms of general atmosphere, curricula, grading criteria, and student status. The results indicate that private higher education was appreciated slightly more than state higher education; both professors and students held more positive attitudes of private higher education for all dimensions investigated.     

The combined effect of self-efficacy and academic integration on higher education students studying IT majors in Taiwan

The purpose of this study is to examine the combined effect of self-efficacy and academic integration on higher education students studying IT (Information Technology) majors in Taiwan. We introduced self-efficacy, which is a psychological factor that affects students’ academic outcomes, as a new factor in Tinto’ theory, a well-known framework in student retention research. Academic integration is the main proposition of Tinto’s theory affecting students’ decision to dropout. Students from different populations have various reasons from dropping out of their studies. An examination of the relationship between self-efficacy and academic integration is useful to understand the effect of self-efficacy on academic outcomes on the IT student population in Taiwan. Data from a Taiwanese national survey database conducted in 2005 was used to achieve the research objective. A total of 2,895 records were extracted from 75,084 students in public and private institutions studying in two IT-related Majors, namely Information Management (IM) and Computer Science (CS). MANOVA was used to analyze the interaction effects between academic integration and self-efficacy. The independent variables were institution types and students’ majors. The results showed that students from public institutions have higher levels of self-efficacy than students from private ones. Another finding is that IM students seem to have better study strategies and habits than CS students. However, CS students were found to have better collaboration and satisfaction with their institutions than IM students. Team projects, counselling services, and flexible teaching and learning strategy are suggested to enhance students’ academic integration and self-efficacy.     

The Role of Life-Space,Social Activity,and Depression on the Subjective Memory Complaints of Community-Dwelling Filipino Elderly: A Structural Equation Model

Subjective memory complaints are one of the major concerns of the elderly and remain a challenging area in gerontology. There are previous studies that identify different factors affecting subjective memory complaints. However, an extended model that correlates life-space on subjective memory complaints remains a blank spot. The objective of this study is to investigate the role of life-space, social activity and depression on subjective memory complaints among the selective group of Filipino elderly in the community. To test the factors affecting subjective memory complaints, a structural equation modeling was employed among all parameters. One hundred eighty-nine Filipino elderly aged 60 years and above located in Parañaque City, Makati City and Malabon City were given a multiaspect questionnaire consisting of a robotfoto, Life-Space Assessment (LSA), Research and Development (RAND) Social Health Battery, Geriatric Depression Scale (GDS), and Subjective Memory Questionnaire (SMQ). Results revealed that life-space and social activity inversely affect depression while subjective memory complaints are directly affected by depression. New pathways emerged suggesting the interrelationship between life-space and social activity. Additionally, social activity directly affects subjective memory complaints. This study provides a confirmation of the impact of the factors affecting subjective memory complaints. Incorporation of these factors into the existing practice can help the health care providers in optimizing the quality of care rendered and quality of life of the elderly.     

Biotechnology teaching models: what is their role in technology education?

The introduction of technology education in New Zealand provided an opportunity to teach biotechnology from a technological perspective. Biotechnology teaching models were developed during a professional development programme. The role of these teaching models has been described and analysed according to the definitions identified by the 'Models in Science and Technology: Research in Education' (MISTRE) group and classified according to Grosslight et al.'s analysis of models in order to identify and analyse the role of biotechnology teaching models in technology education. These teaching models fulfilled a variety of roles that included providing a focus to understanding the factors influencing a biotechnological outcome to providing a technique for collaborative evaluation of manipulative skills in microbial plating exercises.     

An analysis of role conflict and role ambiguity within the cancer information service's communication network

This research examines the relationship between individuals' positions in a communication network and their corresponding levels of role conflict and role ambiguity. As part of a larger research program, the data for this study were collected at two points in time from members within the Cancer Information Service (N = 56), an award winning information service of the National Cancer Institute. In general, findings suggest lower levels of role conflict and ambiguity experienced by members of the CIS. In addition, neither the role conflict model nor the role ambiguity model were consistent with the data. Revised models, however, did suggest that experiencing role conflict and role ambiguity may lead to a decrease in the perception that a person is powerful within one's network. In addition, as members' interpersonal contacts increased, levels of role conflict and role ambiguity between regional offices and the National Cancer Institute decreased. The implications of these results for the CIS and other organizations are discussed.     

Changing Perspectives: Exploring a pedagogy to examine other perspectives about stem cell research

This study explores how teachers developed and critically evaluated a range of teaching strategies that could support the discussion of a socio-scientific issue (SSI) that had the potential to be controversial. The issue was stem cell research and six New Zealand teachers of senior biology students (grades 12/13) took part in an action research project that was situational, collaborative and self-evaluative. The focus of the research was to identify communication barriers that interfered with classroom discussion and how teachers could help students cross cultural borders when they discussed SSIs that were outside their life worlds. The barriers to communication were access to relevant science knowledge, religion, language, an inability to question issues and cultural expectations of girls. Teachers trialled and adapted two discussion strategies, ‘Drawing the Line’ and ‘Diamond Ranking’ that provided a vehicle for their students to explore and discuss this issue from a range of perspectives. These discussion strategies enabled their students to take part in a dialogue where reciprocal conversation could occur because they had opportunities not only to explore their own perspectives but also other people's viewpoints.
