Visual statistical learning in children with and without DLD and its relation to literacy in children with DLD

Reading and Writing - Visual statistical learning (VSL) has been proposed to underlie literacy development in typically developing (TD) children. A deficit in VSL may thus contribute to the...     

Developing the ability to recontextualise cellular respiration: an explorative study in recontextualising biological concepts

In many science education practices, students are expected to develop an understanding of scientific knowledge without being allowed a view of the practices and cultures that have developed and use this knowledge. Therefore, students should be allowed to develop scientific concepts in relation to the contexts in which those concepts are used. Since many concepts are used in a variety of contexts, students need to be able to recontextualise and transfer their understanding of a concept from one context to another. This study aims to develop a learning and teaching strategy for recontextualising cellular respiration. This article focuses on students’ ability to recontextualise cellular respiration. The strategy allowed students to develop their understanding of cellular respiration by exploring its use and meaning in different contexts. A pre- and post-test design was used to test students’ understanding of cellular respiration. The results indicate that while students did develop an acceptable understanding of cellular respiration, they still had difficulty with recontextualising the concept to other contexts. Possible explanations for this ack of understanding are students’ familiarity with the biological object of focus in a context, the manner in which this object is used in a context and students’ understanding of specific elements of cellular respiration during the lessons. Although students did develop an adequate understanding of the concept, they do need more opportunities to practice recontextualising the concept in different contexts. Further research should focus on improving the strategy presented here and developing strategies for other core concepts in science.     

Systems Modelling and the Development of Coherent Understanding of Cell Biology

This article reports on educational design research concerning a learning and teaching strategy for cell biology in upper‐secondary education introducing systems modelling as a key competence. The strategy consists of four modelling phases in which students subsequently develop models of free‐living cells, a general two‐dimensional model of cells, a three‐dimensional model of plant cells, and finally they are engaged in formal thinking by modelling life phenomena to a hierarchical systems model. The strategy was thought out, elaborated, and tested in classrooms in several research cycles. Throughout the field‐tests, research data were collected by means of classroom observations, interviews, audio‐taped discussions, completed worksheets, written tests, and questionnaires. Reflection on the research findings eventuated in reshaping and formalizing the learning and teaching strategy, which is presented here. The results show that although acquiring systems thinking competence at the metacognitive level needs more effort, our strategy contributed to improving learning outcomes; that is, acquisition of a coherent conceptual understanding of cell biology and acquisition of initial systems thinking competence, with modelling being the key activity.     

Designing innovative learning environments to foster communities of learners for students in initial vocational education

In this study, the concept of ‘community of learners’ was used to improve initial vocational education. The framework of a ‘community of learners for vocational orientation’ that we present offers both a theoretical understanding of teaching–learning processes in initial vocational education and heuristics for the design of innovative learning environments for optimising these processes. In a design research study, we investigated if, and how, learning environments designed on the basis of these heuristics fostered communities of learners for vocational orientation, in which students experience to learn in a shared, meaningful, reflective and transfer-oriented way. We examined students’ perceptions of the learning environment and their learning activities during eight curriculum units specifically designed to foster the communities of learners. During almost all of the units that we designed, students found themselves learning in a more shared, meaningful, reflective and transfer-oriented way than during regular units. We conclude that the proposed heuristics had been useful starting points for the design of innovative learning environments that foster communities of learners for vocational orientation. In addition, we show how the heuristics can be elaborated for a particular school, based on practical and pedagogical content knowledge of teachers, as well as students’ perceptions of the learning environment and their learning activities.     

Academic self-concept in elementary learning disabled children: Study with the student's perception of ability scale

Academic self-concept as measured by the Student's Perception of Ability Scale (SPAS) was compared for 81 learning disabled (LD) and 81 normally-achieving control children in grades three to six. The results show that LD children hold significantly more negative self-perceptions of ability in reading, spelling, and arithmetic than do the control children. Further, these negative school subject-related attitudes in the LD children had generalized to lower self-perceptions of ability in general, to expressions of less confidence in school, and more negative attitudes toward school. No grade level or sex effects were observed. It was concluded that the SPAS is able to discriminate between normally-achieving children and those experiencing problems in school, and, accordingly, that the SPAS has good external validity. The results were discussed in terms of using the SPAS for evaluating affective components of remediation, and for identifying high-risk elementary school children. Continuing external validity studies being undertaken by the authors also were noted.     

Objective and subjective knowledge and higher education in agriculture

Abstract

The way of thinking about nature and the relation between man and nature is considered as a basis for the current problems in agriculture and environment. Distinctive features of this way of thinking are rationalism, empiricism, reductionism and objectivism.

Education, especially higher education, is very much aiming at rational and disciplinary development. The intuitive and subjective knowledge does not get a chance to be linked with the rational, objective knowledge. As teachers we try to realise this connection within a subject for students at the Agricultural Teacher Training Institute (STOAS) in Den Bosch and within a subject for students at the Wageningen Agricultural University (WAU). In this subject we have the students learn to be aware of their own attitude towards the environment and to get hold of their own instruments for evaluating agricultural systems and agricultural research. The way in which the environment is perceived is an important part of the training.

The ordinary methods used in higher education are not very suitable for teaching subjective knowledge. With our methods we try to stimulate the students to use their intuitive and creative capacities. We experienced that the students liked working in a way that demands more of their personal capacities beyond the rational ones. Most of them were enthusiastic, even those who were at first critical and reserved. As result of the training the students had become more aware of their own views, of the value of intuition and feeling, and of the limitations of the western world view and scientific thinking.

We found that it is not possible to make a fixed programme. It depends on the group how it will exactly be filled in. So, as a teacher you have to be flexible and you need to have an open eye and ear for the questions and possibilities of the students.     

Organizing the University-Industry Relationship: A case study of research policy and curriculum restructuring at the North-West University in South Africa

A major requirement for transformation contained in the new education policy in South Africa is that the graduate outputs of the higher education system should match the needs of a modernizing economy. This paper addresses the organizational aspect of university-industry relationships that is an element of the transformation. In empirical terms, it reflects upon the policy of the North-West University in South Africa, as embodied by means of the introduction of the Business Mathematics and Informatics (BMI) curriculum and research. Empirical results indicate that the number of students who opted for mathematics had increased dramatically. The majority of graduates delivered by the BMI programme are employed in the financial sector, both nationally and internationally. This paper indicates that the organization of university-industry relationships enforces a difficult institutional balancing act that attempts, on the one hand, to meet the benchmark of international scientific indicators, and on the other hand, “fitness for purpose” in the local context.
