Compiling an evidence-based improvement plan for the support of distance-education students at a southern African university

This article illustrates how an event guide can be used to organise, systematise and prioritise the large amount of findings from an extensive study. The study aimed to enhance student support at a distance-education institute in a Southern African country (Lesotho). In this case study an improvement-oriented evaluation of the strengths, weaknesses and constraints of the current situation at this University was undertaken. Data collection resembled a triangulation mixed-methods design which included questionnaire surveys and focus-group discussions among the students and lecturers in a distance-education programme. A resource inventory was also drawn up. Based on the merged findings, a strengths-weaknesses-opportunities-threats (SWOT) table was drawn up. The findings clearly depicted the difficulties associated with the provision of quality support for distance learners in a developing country with relatively weak infrastructure and few resources. The main purpose of the article, however, is to describe how the findings and the implicated actions needed for improvement were organised to compile an improvement plan by means of an event guide which consists of a series of event tracks. The article not only shares valuable perspectives about improving the support for distance learners in a developing environment, but also introduces a practical way of organising key findings from research in a way that potentially encourages action and implementation, particularly in an area and context where improvement is of critical importance.

Developing Self-Efficacy in Teaching Mathematics: Pre-Service Teachers’ Perceptions of the Role of Subject Knowledge

ABSTRACT

Two major concerns in mathematics teacher education are the role of subject matter knowledge and the development of self-efficacy in pre-service teachers. This article brings these issues together in an exploration of the interaction between pre-service teachers’ perceptions of their subject matter knowledge and their accounts of university and placement experiences as potential sources of self-efficacy. Reporting on a group of ten pre-service teachers in Norway, we explore variations in the ways in which they perceived the role of subject knowledge in relation to experience, particularly “mastery experiences”, over a period of nearly two years. We suggest that recognition of the role of “understanding why” in mathematics is crucial in the experience of mastery, and that there is a need to focus more on the role of subject matter knowledge in all sources of self-efficacy in teaching mathematics.     

Computer Simulations Improve University Instructional Laboratories

Laboratory classes are commonplace and essential in biology departments but can sometimes be cumbersome, unreliable, and a drain on time and resources. As university intakes increase, pressure on budgets and staff time can often lead to reduction in practical class provision. Frequently, the ability to use laboratory equipment, mix solutions, and manipulate test animals are essential learning outcomes, and “wet” laboratory classes are thus appropriate. In others, however, interpretation and manipulation of the data are the primary learning outcomes, and here, computer-based simulations can provide a cheaper, easier, and less time- and labor-intensive alternative. We report the evaluation of two computer-based simulations of practical exercises: the first in chromosome analysis, the second in bioinformatics. Simulations can provide significant time savings to students (by a factor of four in our first case study) without affecting learning, as measured by performance in assessment. Moreover, under certain circumstances, performance can be improved by the use of simulations (by 7% in our second case study). We concluded that the introduction of these simulations can significantly enhance student learning where consideration of the learning outcomes indicates that it might be appropriate. In addition, they can offer significant benefits to teaching staff.     

Using three levels in design of effective teacher-education tasks: The case of promoting conflicts with intuitive understandings in probability

This paper describes a three-level framework (technical, domain, and generic) which enables some generalisability across mathematics topics for effective teacher–education (TE) task design. It argues that TE tasks which encompass these levels increase preservice and inservice teachers’ interest because they transcend the particular mathematical focus and pedagogical activity within the TE tasks and enable translation to classrooms (technical), enhance the success of student learning (domain), and facilitate transfer to other topics (generic). The paper then uses the levels to analyse an effective probability task (based on circular spinners) which involves cognitive conflict between formal and intuitive probability at all three levels, namely, with regard to facilitating non-random results (technical), differences between probabilistic and deterministic mathematics and area and set models (domain), and non-prototypic exemplars and validation in probability experiments (generic). The paper concludes with reference to the power of effective TE tasks in showing how connectivity of mathematics (e.g., fractions and probability) requires similar connectivity in pedagogy.     

Contacts with classmates: the social position of pupils with Down's syndrome in Dutch mainstream education

ABSTRACT

An important aspect of integrating special needs pupils in mainstream education is social integration. Parents of Down's syndrome children and their teachers in regular education regard contact with peers as of utmost importance for these children's development. Until recently, there was little research in The Netherlands on social contact between mainstream Down's syndrome children and their classmates. The study addresses the number and type of contacts in the regular classroom and the position occupied by the pupils involved within their peer group in regular education.     

A cross-disciplinary approach to teaching data literacy and proportionality

The Thinking with Data project (TWD) expands on current notions of data literacy by (1) focusing on proportional reasoning as key to data literacy and (2) leveraging the non-mathematics disciplines to engage students in deep thinking about the context of data and the application of proportionality. A set of four 2-week, sequential modules for cross-disciplinary implementation in seventh-grade classrooms was designed and evaluated. Using a quasi-experimental approach, we found that student data literacy was increased through the focused integration of social studies, mathematics, science, and English language arts. In this article, we describe our theoretical approach to designing and implementing the modules, report on student learning gains in mathematics, and describe teacher reactions to the materials. In sum, our study provides evidence that the TWD approach has the potential to build data literacy while also allowing students to learn core discipline-based content standards.     

Reconstructing Iconic Experiments in Electrochemistry: Experiences from a History of Science Course

The decomposition of water by electricity, and the voltaic pile as a means of generating electricity, have both held an iconic status in the history of science as well as in the history of science teaching. These experiments featured in chemistry and physics textbooks, as well as in classroom teaching, throughout the nineteenth and twentieth centuries. This paper deals with our experiences in restaging the decomposition of water as part of a history of science course at the Norwegian University of Science and Technology, Trondheim, Norway. For the experiment we used an apparatus from our historical teaching collection and built a replica of a voltaic pile. We also traced the uses and meanings of decomposition of water within science and science teaching in schools and higher education in local institutions. Building the pile, and carrying out the experiments, held a few surprises that we did not anticipate through our study of written sources. The exercise gave us valuable insight into the nature of the devices and the experiment, and our students appreciated an experience of a different kind in a history of science course.
