Educational Histories and Academic Potential: can tests deliver?

Matriculation results for applicants from the turbulent and under‐resourced South African Department of Education and Training system have consistently proved to be an unreliable indicator of future academic performance, particularly in the lower pass ranges. While urgent attention is being paid to the improvement of education in the country, the legacy of apartheid divisions and inequities will remain for some time. The Alternative Admissions Research Project at the University of Cape Town has developed, and performs research on, tests that indicate ability to cope with English‐medium academic education. These tests are used to provide additional access opportunities for students from disadvantaged educational backgrounds. In order to avoid developing tests that in effect only predict the past, the project has embarked upon an innovative approach designed to take seriously the effects of educational disadvantage, and to minimise reliance on content‐based secondary school experiences. This approach incorporates central principles from constructivist learning theories, most centrally that learning is an active, constructive process. In the tests being used and developed by the project, these principles take shape in an increased focus on the role played by questions and tasks within tests in terms of the provision of opportunities for learning to take place. The paper reports preliminary results from this testing approach.     

Pre-service Teachers' Preferred Strategies for Solving Arithmetic and Algebra Word Problems

In this study we investigate the arithmetic andalgebra word problem-solving skills andstrategies of future primary and secondaryschool teachers in Flanders (Belgium).Moreover, we describe the evolution of theseskills and strategies from the beginning to theend of their teacher education. The resultsshow that future secondary school mathematicsteachers preferred the use of algebra, evenwhen an arithmetic solution was morestraightforward. The solutions of futureprimary school teachers were more diverse: onesubgroup tended to apply exclusively arithmeticmethods (which led to failures on the mostdifficult word problems), whereas anothersubgroup was more adaptive in its strategychoices. Finally, student teachers evolved intheir problem-solving skills during theirteacher education, but not in their strategypreferences. The research findings indicatethat, in the education of pre-service primaryand secondary school teachers, there is a needfor an explicit treatment of pupils' transitionfrom arithmetical to algebraic thinking.     

Firm-related training tracks: a random effects ordered probit model

A random effects ordered response model of training is estimated to analyze the existence of training tracks and time varying coefficients in training frequency. Two waves of a Dutch panel survey of workers are used covering the period 1992–1996. The amount of training received by workers increased during the period 1994–1996 compared to 1992–1994. Evidence is found for the existence of training tracks in the amount of training courses taken. It is further found that the effects of individual characteristics such as education, age and gender on training should be treated as individual varying coefficients.     

Stimulating pre-service teachers’ content and pedagogical content knowledge on rational numbers

This study explored the perspectives of mathematics teacher educator-researchers (MTE-Rs) on the use of theory in facilitating teacher growth. We adopted the framework of the theory-centered scholarship triangle (Silver & Herbst, 2007) to probe the underlying meanings of perspectives on theory use expressed by MTE-Rs. Qualitative analysis revealed three distinct types of perspectives: a perspective focusing on research, a perspective focusing on practice, and a perspective on the connection between research and practice. For the perspective on the connection between research and practice, two sub-categories were identified: connection with consideration of context and that without consideration of context. Different perspectives that MTE-Rs possess may influence their actions taken in professional development and consequently influence teachers’ learning of theory. Specifically, the cyclic process of decontextualizing and recontextualizing theory between research and practice domains is the key to the development of MTE-Rs’ educative power so that they can better facilitate teachers in learning theory.     

Refutational text and multiple external representations as a method to remediate the misinterpretation of box plots

The ability to interpret graphs is highly important in modern society, but has proven to be a challenge for many people. In this paper, two teaching methods were used to remediate one specific misinterpretation: the area misinterpretation of box plots. First, we used refutational text to explicitly state and invalidate the area misinterpretation of box plots. Second, we used multiple external representations (MERs): Histograms were used as an overlay on box plots in order to give students a better insight in the way box plots represent data distributions. Third, we combined refutational text and MERs. We found that refutational text was successful in improving students’ interpretation of box plots, but that the use of MERs did not improve students’ interpretation of box plots. The addition of MERs also did not increase the effect of refutational text.     

How do high school students solve probability problems? A mixed methods study on probabilistic reasoning

When studying a complex research phenomenon, a mixed methods design allows to answer a broader set of research questions and to tap into different aspects of this phenomenon, compared to a monomethod design. This paper reports on how a sequential equal status design (QUAN → QUAL) was used to examine students’ reasoning processes when solving probability problems. A select clustered sampling resulted in the inclusion of 168 high school students in a first, quantitative phase, in which a questionnaire was used to assess how they solved probability problems. This questionnaire included probability items that were based on the outcome orientation, the representativeness misconception, and the equiprobability bias. In a second, qualitative phase, 18 students who were purposefully sampled from the first research phase were interviewed in order to conduct an in-depth study of their probabilistic reasoning processes. In this paper, we illustrate and discuss how several mixed methods research purposes were realized throughout our study: development, expansion, and initiation.     

Mode of acquisition as a factor in deaf children's reading comprehension

This article examines the role of mode of acquisition (MoA) of word meanings in reading comprehension: children acquire word meanings using perceptual information (e.g., hearing, seeing, or smelling the referent) and/or linguistic information (e.g., verbal explanations). A total of 72 deaf and 99 hearing children between 7 and 15 years of age performed a self-paced reading task. Comprehension scores increased with age in both groups, but reading speed increased over age only for the hearing participants. For both groups, reading times on linguistically acquired words were longer than on perceptually acquired words. Although deaf children scored lower than hearing children in both conditions, comprehension scores for both groups were lower on linguistic items than on perceptual items. Thus, MoA influences reading comprehension, but the deaf show difficulty on both the perceptual and the linguistic items.     

Community Schools As An Educational Alternative In Africa: A Critique

With a view to basic formal education, this study explores actual experiences and potential values of current community-school initiatives in Africa. Using data from different programmes around the continent, it examines their dynamics in terms of various conceptions about alternative provisions for basic education. The wider policy question posed is whether community schools can respond in a meaningful and viable manner to the interests of learners and their communities, meet social-policy goals of equity and social justice, and foster reform. While its conclusions remain tentative, the study explores effective but problematic approaches supported by communities, non-governmental organizations and governments. It gives particular attention to those elements promoting empowerment and transforming educational provision and local socio-economic conditions. It also raises fundamental questions about sustainability and equity as well as the responsiveness of schools to community needs and their ability to assist learners in overcoming disadvantage and marginality.     

Foreign Students in Engineering Education

Institutions for higher engineering education encourage the admission of foreign students, mostly for economic reasons. Data from the situation of foreign students at Delft University of Technology, however, show that admitting foreign students will be profitable only if the students are carefully selected in the country of origin. Furthermore, language proficiency must play an important role in the procedure of admission in the host country. Foreign students' academic achievement has proven to be sufficient although the students appear to suffer from starting problems. Offering social and educational support at the beginning of their stay abroad may help to overcome problems of adjustment. As yet, any possible positive effects of the presence of foreign students on the quality of education or on the general education of regular students in the host country have not been empirically established. They seem to depend highly upon the amount of interaction between foreign and regular students.     

Simulating serious games: a discrete-time computational model based on cognitive flow theory

This paper presents a computational model for simulating how people learn from serious games. While avoiding the combinatorial explosion of a games micro-states, the model offers a meso-level pathfinding approach, which is guided by cognitive flow theory and various concepts from learning sciences. It extends a basic, existing model by exposing discrete-time evolution, allowing for failure, drop-out, and revisiting of activities, and accounting for efforts made and time spent on tasks, all of which are indispensable elements of gaming. Three extensive simulation studies are presented involving over 10,000 iterations across a wide range of game instances and player profiles for demonstrating model stability and empirical admissibility. The model can be used for investigating quantitative dependences between relevant game variables, gain deeper understanding of how people learn from games, and develop approaches to improving serious game design.
