Hybrid sliding mode observer for switched linear systems with unknown inputs

This paper addresses the state observation and unknown input estimation of a class of switched linear systems with unknown inputs. This class of systems may have modes in which the state is not fully observable. A state transformation allows implementing two suitable reduced-order observers. The first one, based on second order sliding mode techniques, is proposed to reconstruct the discrete state in the presence of unknown inputs. The second one, based on gathering partial information from individual modes of the switched system and on higher order sliding mode techniques, is introduced to estimate the continuous state. Then, the observer injection signal of the first second order sliding mode observer is used to estimate the unknown inputs. Simulation results highlight the efficiency of the proposed method.     

Student and novice teachers’ stories about collaborative learning implementation

Despite the research evidence on the effectiveness of collaborative learning (CL), the implementation of this teaching strategy has not yet found a profound place in teaching practice. As a consequence, several studies have investigated teachers’ motives regarding and experiences with the use of CL. Most of these studies concern however senior teachers, whereas new generations of teachers are important actors in the process of educational innovation. Hence, it is crucial to explore novice teachers’ stories about CL implementation: what motivates them to implement this teaching strategy, what hinders them and how do they handle the challenges they are confronted with? The answers to these questions may provide useful information for improving the teacher education curriculum regarding CL. In this respect, the present study intends to study pre-service and beginning teachers’ experiences with CL in classroom practice, after a formal training pertaining to CL as part of their teacher education programme. The aim is to identify the main challenges student and novice teachers encounter when they want to implement CL in their teaching practice, and how they position themselves in these challenges. A qualitative case study design with in-depth interviews in the Flemish context (Belgium) was used to gain access to the particular experiences of each teacher, and to the processes of interpretation and meaning-making that go with those experiences. Participants were interviewed individually one week before graduation (n?=?15). After at least half a year of experience in the teaching profession, 10 participants were interviewed for a second time. In the present study, we present the results from a cross-case analysis, using the method of constant comparative analysis to identify similarities or differences, and to capture recurring patterns within the data. The findings reveal several dilemmas that illustrate the conflicting options teachers are facing in relation to their colleagues, their pupils, the curriculum and in the classroom context when they intend to implement CL. In particular, the following dilemmas were identified: two dilemmas related to professional autonomy (student teachers: teacher autonomy vs. pre-service performance assessment; novice teachers: teacher autonomy vs. institutional conformity), further dilemmas related to teachers’ beliefs about pupils’ readiness for CL vs. evidence about pupils’ readiness for CL, investing in innovation vs. curriculum and job pressure, and pedagogical intentions vs. contextual constraints. In most conflicting situations, student and novice teachers position themselves in the challenge by opting for non-implementation.     

Clustering teachers' motivations for teaching

The motivation to teach is a powerful, yet neglected, force in teaching at institutes of higher education. A better understanding of academics' motivations for teaching is necessary. The aim of this mixed-method study was to identify groups with distinctively different motivations for teaching. Six clusters were identified: expertise, duty, subject, passion, reluctance and incompetence. The teachers in these groups differed in perceived personal effectiveness, interest and effort towards teaching. Interview data revealed the competitive function of research and the importance of the subject matter taught. The clusters containing teachers who prioritise the teaching process over the teaching content were the ones with the highest overall motivation scores.     

Perspectives on teaching and regulation of learning: a comparison of secondary and university teachers

Many factors play a role in the successful transition of students from secondary to university education: one of them is the (university) teacher. In this study the similarities and differences in the perspectives on teaching and learning of secondary and university teachers were investigated. A survey was performed among 675 teachers. Three perspectives on teaching and learning could be distinguished: (1) a development orientation with shared regulation, (2) a knowledge orientation with strong regulation, and (3) an opinion orientation with loose regulation. Secondary teachers scored higher on the first perspective than university teachers who scored higher on the third perspective. These findings have implications for the transition of students from pre-university to university education and especially for teachers' roles.     

Realising graduate attributes in the research degree: the role of peer support groups

This paper discusses the role of peer support groups (PSGs) in realising graduate attributes in the research degree. The literature indicates that top-down embedding of graduate attributes has met with only limited success. By taking a bottom-up approach, this paper shows that PSGs offer an opportunity to improve the graduate attribute outcomes of universities. This paper presents the experiences of research students in three PSGs in New Zealand, Australia and Malaysia, and the results of an exploratory opinion survey that required past and present PSG members to share their learning experiences about the development of graduate attributes. The participants favoured five attributes: communication, critical thinking, self-motivation, research organisation and teamwork. Viewing the development of graduate attributes through the lens of the students adds to our understanding of how PSGs help them to develop graduate attributes and contribute to university efforts to instil these attributes by taking into account experiential learning.     

The Effectiveness of a Faculty Training Programme: Long‐term and institutional impact

Long‐term influences of educational development initiatives for novice faculty members are seldom studied in a systematic way. In this exploratory study the long‐term individual and institutional impact of a novice faculty training programme at the University of Antwerp (Belgium) was evaluated, using a written survey with open questions. The results revealed that 2 years after finishing the programme the respondents still referred to the programme as a means of explaining changes in their day‐to‐day teaching practice. No firm relationship could be established between the strength of individual impact and the extent to which respondents also felt inclined to change things at the institutional level. The data suggests that the long‐term impact of the programme depends mainly on contextual elements. The article further discusses implications for the design of faculty training as well as perspectives for further research.

Onderzoek naar de invloed op lange termijn van onderwijskundige professionalisering voor beginnende docenten is schaars. Dit artikel bespreekt de resultaten van een exploratieve studie over de lange termijn invloed van een opleiding voor beginnende docenten aan de universiteit van Antwerpen (België). Met behulp van een schriftelijke vragenlijst met open vragen werd de invloed van de opleiding op individueel en institutioneel niveau nagegaan. De resultaten tonen aan dat de respondenten twee jaar na datum nog steeds naar de opleiding verwijzen wanneer zij veranderingen in hun dagelijkse onderwijspraktijk duiden. Vastgesteld werd dat docenten die getuigen van sterke veranderingen in hun onderwijsopvattingen, ook meer omvattende veranderingen in hun praktijk beschrijven. Er werd geen verband gevonden tussen de sterkte van de veranderingen op individueel niveau en de mate waarin docenten zich geroepen voelden om veranderingen op institutioneel niveau teweeg te brengen. De resultaten laten vermoeden dat de lange termijn invloed van de opleiding vooral afhangt van contextfactoren. Het artikel gaat in op de implicaties van de bevindingen voor het ontwerp van onderwijskundige professionalisering en op de uitdagingen voor verder onderzoek.

L'influence à long terme des initiatives de développement pédagogique destinées aux enseignants universitaires en début de carrière est rarement étudiée de façon systématique. Dans le cadre de cette étude exploratoire, l'impact à long terme et pour l'institution d'un programme de formation pour les nouveaux enseignants donné à l'Université d'Anvers (Belgique) a été évalué à l'aide d'un questionnaire écrit comportant des questions ouvertes. Les résultats tendent à démontrer que, même deux ans après avoir complété le programme, les répondants faisaient toujours référence au programme pour expliquer les changements survenus dans leur pratique quotidienne d'enseignement. Bien que les changements comportementaux correspondent à l'étendue du changement en matière de conceptions de l'enseignement, aucune relation nette n'a pu être établie entre l'impact institutionnel et la vigueur de l'impact individuel. Les données tendent à démontrer que l'impact à long terme du programme dépend principalement d'éléments contextuels. L'article présente aussi des éléments de discussion relatifs au design d'activités de formation pour les enseignants, de même que de nouvelles perspectives de recherche.     

Supports for children with disabilities in regular education classrooms: an account of different perspectives in Flanders

This paper presents the experiences and interpretations of children, parents, teachers and support persons concerning the implementation of supports in regular school environments in Flanders, Belgium. The data were gathered through observations, interviews and focus group meetings. Those multiple perspectives provide insights into the complexity of implementing supports in a regular education context. The conclusions offer some possibilities for debate and alternative ways of thinking about supports that facilitate inclusive school communities by tapping into resources such as the children, the environment, creativity and courage to leave the beaten path.     

The influence of closing poor performing primary schools on the educational attainment of students

This paper examines whether the closure of poor performing primary schools improved students' educational attainment. It is believed that school closure affects children's educational outcomes positively because children switch to better primary schools. At the same time, school closure creates a social disturbance such that educational outcomes may be affected negatively. There is no previous literature on the effect of this type of school closure on student performance. The empirical results indicate that student test scores are not affected by the school closure. Children are, however, tracked into higher secondary education levels after the school closure if they received more education years at the new primary school. This effect fades out and eventually becomes negative for children who received more than one education year at the new primary school. The results further suggest that there are no detrimental effects of a school closure in terms of educational performance.     

Improving the Entrepreneurial Competencies of Dutch Dairy Farmers through the Use of Study Groups

Abstract

The objective of this paper is to describe and analyse the role that study groups might play in improving the entrepreneurial competencies of farmers. The most important competencies are described. Emphasis is placed on group learning processes and participatory approaches. Theories of adult learning and extension paradigms in relation to our experiences in the ‘Innovative Entrepreneurship’ study are addressed. We conclude that in our research, participatory approaches and using study groups are an aid to gaining explicit and implicit knowledge. Consequently, they are effective methods for training entrepreneurial competencies and creating an environment in which participants are able to learn effectively.     

Learning Styles of Chinese and Dutch Students Compared within the Context of Dutch Higher Education in Life Sciences

Abstract

This study investigated the extent to which the learning styles of Chinese students differ from those of Dutch students. The study was conducted within the context of Englishlanguage Bachelor of Science programmes thatWageningen University offers together with China Agricultural University to Dutch and Chinese students. Sixteen Dutch students and 25 Chinese students completed the Inventory of Learning Styles. The Chinese students have several of the characteristics that reflect a reproduction-directed and an undirected learning style, while the Dutch students as a group do not demonstrate any one particular learning style. It would be useful and desirable to show the Chinese students, by means of specific instructions and exercises, how to use strategies directed towards deep processing and how to regulate their own learning processes more in the direction of deep processing.
