Thought structures of modelling task solutions and their connection to the level of difficulty
(2015)
Although efforts have been made to integrate the concept of mathematical modelling in school, among others PISA and TIMSS revealed weaknesses of not only German students in the field of mathematical modelling. There may be various reasons starting from educational policy via curricular issues to practical instructional concerns. Studies show that mathematical modelling has not been arrived yet in everyday school class (Blum &BorromeoFerri, 2009, p. 47). Thus, the proportion of mathematical modelling in everyday school classes is low (Jordan et al., 2006). When focusing on the teachers’ point of view there are difficulties which may contribute to avoid modelling tasks in class. The development of reasonable modelling tasks, estimating the task space, valuating the task difficulty and assessing the student solutions are difficulties which occur to an increasing degree compared to ordinary mathematics tasks.The project MokiMaS (transl.: modeling competency in math classes of secondary education) aims at providing inter-year modelling tasks, whose task space and level of difficulty is known, together with an evaluation scheme. In particular a theory based method has been developed to determine the level of difficulty of modelling tasks on the basis of thought structures, representing the cognitive load of solution approaches. The current question is whether this method leads to a realistic rating. To go further into that question an evaluation scheme has been developed which is guided by the daily assessment work of teachers, to investigate the relation of task difficulty and student performance.
Worldwide, in Africa and in South Africa, the importance of the doctorate has increased disproportionately in relation to its share of the overall graduate output over the past decade. This heightened attention has not only been concerned with the traditional role of the PhD, namely the provision of future academics; rather, it has focused on the increasingly important role that higher education - and, particularly, high-level skills - is perceived to play in national development and the knowledge economy. This book is unique in the area of research into doctoral studies because it draws on a large number of studies conducted by the Centre of Higher Education Trust (CHET) and the Centre for Research on Evaluation, Science and Technology (CREST), as well as on studies from the rest of Africa and the world. In addition to the historical studies, new quantitative and qualitative research was undertaken to produce the evidence base for the analyses presented in the book. The findings presented in Doctoral Education in South Africa pose anew at least six tough policy questions that the country has struggled with since 1994, and continues to struggle with, if it wishes to gear up the system to meet the target of 5 000 new doctorates a year by 2030. Discourses framed around the single imperatives of growth, efficiency, transformation or quality will not, however, generate the kind of policy discourses required to resolve these tough policy questions effectively. What is needed is a change in approach that accommodates multiple imperatives and allows for these to be addressed simultaneously.
The search for answers to the issue of global sustainability has become increasingly urgent. In the context of higher education, many universities and academics are seeking new insights that can shift our dependence on ways of living that rely on the exploitation of so many and the degradation of so much of our planet. This is the vision that drives SANORD and many of the researchers and institutions within its network. Although much of the research is on a relatively small scale, the vision is steadily gaining momentum, forging dynamic collaborations and pathways to new knowledge. The contributors to this book cover a variety of subject areas and offer fresh insights about chronically under-researched parts of the world. Others document and critically reflect on innovative approaches to cross-continental teaching and research collaborations. This book will be of interest to anyone involved in the transformation of higher education or the practicalities of cross-continental and cross-disciplinary academic collaboration. The Southern African-Nordic Centre (SANORD) is a network of higher education institutions from Denmark, Finland, Iceland, Norway, Sweden, Botswana, Namibia, Malawi, South Africa, Zambia and Zimbabwe. Universities in the southern African and Nordic regions that are not yet members are encouraged to join.
There has been a resurgence of interest in training programmes for higher education leaders and management (HELM) at African universities in recent times. Although there have been a few cases of evaluation studies of such programmes in Africa, a more systematic review of the lessons learnt through these programmes has not been done. This book aims to document and reflect on the learnings from intervention programmes at three African higher education councils. It is clear that university leaders face many leadership and management challenges. This is the starting point of the book.
'This volume brings together excellent scholarship and innovative policy discussion to demonstrate the essential role of higher education in the development of Africa and of the world at large. Based on deep knowledge of the university system in several African countries, this book will reshape the debate on development in the global information economy for years to come. It should be mandatory reading for academics, policy-makers and concerned citizens, in Africa and elsewhere. - Manuel Castells, Professor Emeritus, University of California at Berkeley, Laureate of the Holberg Prize 2012 and of the Balzan Prize 2013.
Twenty Years of Education Transformation in Gauteng 1994 to 2014: An Independent Review presents a collection of 15 important essays on different aspects of education in Gauteng since the advent of democracy in 1994. These essays talk to what a provincial education department does and how and why it does these things - whether it be about policy, resourcing or implementing projects. Each essay is written by one or more specialist in the relevant focus area. The book is written to be accessible to the general reader as well as being informative and an essential resource for the specialist reader. It sheds light on aspects of how a provincial department operates and why and with what consequences certain decisions have been made in education over the last 20 turbulent years, both nationally and provincially. There has been no attempt to fi t the book's chapters into a particular ideological or educational paradigm, and as a result the reader will find differing views on various aspects of the Gauteng Department of Education's present and past. We leave the reader to decide to what extent the GDE has fulfilled its educational mandate over the last 20 years.
The title of this study is applying team teaching to improve student ability in understanding English narrative texts. The purposes of this study are to identify the advantages and to find out the strategies of applying team teaching to improve students ability in understanding English narrative texts. The population of this study is the first year students of SMAN 4 Banda Aceh, and the sample are an experimental class (X IA 2) and a control class (X IA 6). The total numbers of the samples are 66 students. This research was conducted on April, 2010. In collecting data, several techniques were used namely; observation, test, questionnaire and interview. According to data analysis, team teaching gave more advantages to improve students’ ability in understanding English narrative texts. Some advantages of team teaching to the first year students of SMAN 4 Banda Aceh; (1) Team teaching directed the students to focus on material, the method was not tedious and learning motivation had been increased by using it, so that their ability in understanding English narrative text had been increased. (2) The students who studied by using team teaching obtained higher score than the students who studied without using team teaching. It means the students who studied by using team teaching could improve their abilities in understanding English narrative text. (3) The students should focus on the study because the teachers observed what they do in the class comprehensively. The student also could receive knowledge not only from the main teacher, but also from the co-teacher and they could ask both teachers if they found some problems. Some advantages of team teaching to the teachers of SMAN 4 Banda Aceh are; team teaching could be effective while teaching and learning process was underway because the teachers could remind each other and they also could plan good materials. In applying team teaching to improve students’ ability in understanding English narrative texts, the teachers used many strategies. One of the general strategies to apply team teaching in SMAN 4 Banda Aceh was by excercising the so called semi team teaching. The special strategies that conducted by teachers were; (1) Presenting an interesting and understandable topic in every meeting for students. (2) Making group discussion, reading the legend and translating it, giving regularly the test and games. (3) Asking the students to comprehend the generic structure of the text before coming to the class.
Previous research on working memory (WM) in children with poor mathematical skills has yielded heterogeneous results, possibly due to inconsistent consideration of the IQ-achievement discrepancy and additional reading and spelling difficulties. To examine the impact of both, the WM of 68 average-achieving and 68 low-achieving third-graders in mathematics was assessed. Preliminary analyses showed that poor mathematical skills were associated with poor WM. Afterwards, children with isolated mathematical difficulties were separated from those with additional reading and spelling difficulties. Half of each group fulfilled the IQ-achievement discrepancy, resulting in a 2 (additional reading and spelling difficulties: yes/no) by 2 (IQ-achievement discrepancy: yes/no) factorial design. Analyses revealed that not fulfilling the IQ achievement discrepancy was associated with poor visual WM, whereas additional reading and spelling difficulties were associated with poor central executive functioning in children fulfilling the IQ-achievement discrepancy. Therefore, WM in children with poor mathematical skills differs according to the IQ-achievement discrepancy and additional reading and spelling difficulties.
