Designing Instructional Examples to Reduce Intrinsic Cognitive Load: Molar versus Modular Presentation of Solution Procedures

It is usually assumed that successful problemsolving in knowledge-rich domains depends onthe availability of abstract problem-typeschemas whose acquisition can be supported bypresenting students with worked examples.Conventionally designed worked examples oftenfocus on information that is related to themain components of problem-type schemas, namelyon information related to problem-categorymembership, structural task features, andcategory-specific solution procedures. However,studying these examples might be cognitivelydemanding because it requires learners tosimultaneously hold active a substantial amountof information in working memory. In ourresearch, we try to reduce intrinsic cognitiveload in example-based learning by shifting thelevel of presenting and explaining solutionprocedures from a `molar' view – that focuseson problem categories and their associatedoverall solution procedures – to a more`modular' view where complex solutions arebroken down into smaller meaningful solutionelements that can be conveyed separately. Wereview findings from five of our own studiesthat yield evidence for the fact thatprocessing modular examples is associated witha lower degree of intrinsic cognitive load andthus, improves learning.     

Towards Research-based Innovation and Reform: Singapore schooling in transition

The challenges facing the Singapore education system in the new millennium are unique and unprecedented in Asia. Demands for new skills, knowledges, and flexible competencies for globalised economies and cosmopolitan cultures will require system-wide innovation and reform. But there is a dearth of international benchmarks and prototypes for such reforms. This paper describes the current Core Research Program underway at the National Institute of Education in Singapore, a multilevel analysis of Singaporean schooling, pedagogy, youth and educational outcomes. It describes student background, performance, classroom practices, student artefacts and outcomes, and student longitudinal life pathways. The case is made that a systematic focus on teachers' and students' work in everyday classroom contexts is the necessary starting point for pedagogical innovation and change. This, it is argued, can constitute a rich multidisciplinary evidence base for educational policy.     

The changing pattern of higher education in England and Wales — The end of an era?

During the past twenty years great changes have taken place in British higher education. During the 1980s these changes have been even more noticeable, so that by the middle of the 1990s the pattern and the ethos of British higher education will be very different from that prevailing in the 1970s. Not only have there been structural changes but there have also been concerns about autonomy and freedom, accountability and appraisal in the face of government demands for improved management efficiency, restrictions on tenure and alternative forms of finance. This paper analyses these changes in universities, polytechnics and teacher education colleges and traces the growing intervention on the part of government. It also seeks to draw out implications for other education systems facing the same pressures. A glossary of abbreviations and acronyms appears on p. 301.

Zusammenfassung Während der vergangenen zwanzig Jahre gab es in der britischen Hochschulbildung große Veränderungen. Im Laufe der 80er Jahre sind diese Veränderungen besonders deutlich geworden, und bis zur Mitte der 90er Jahre werden sich die Struktur und das Ethos der britischen Hochschulbildung von den in den 70er Jahren vorherrschenden stark unterscheiden. Es hat nicht nur strukturelle Veränderungen gegeben, sondern auch besorgte Überlegungen zu Fragen der Autonomie und Freiheit, Verantwortlichkeit und Beurteilung angesichts der Forderungen seitens der Regierung nach verbesserter Wirtschaftlichkeit der Verwaltung, Begrenzung der Amtszeiten und alternativen Finanzierungsformen. Im vorliegenden Artikel werden diese Veränderungen an Universitäten, Technischen Hochschulen und Pädagogischen Hochschulen analysiert, und es wird den zunehmenden Eingriffen durch die Regierung nachgegangen. Darüberhinaus wird versucht, Auswirkungen auf andere Bildungssysteme aufzuzeigen, die mit denselben Zwängen konfrontiert sind. Ein Glossar der Abkürzungen und Akronyme erscheint auf S. 301.

Résumé Au cours des vingt dernières années, de grands changements sont intervenus dans l'enseignement supérieur en Grande Bretagne. Ces changements sont devenus encore plus sensibles durant les années 1980, si bien que, vers le milieu des années 1990, la structure et l'éthos de l'enseignement supérieur britannique seront très différents de ceux qui prévalaient dans les années 1970. Non seulement il y a eu des changements structuraux, mais on s'est également préoccupé d'autonomie et de liberté, de responsabilité et d'appréciation en dépit des exigences gouvernementales à l'égard d'une gestion plus efficace, d'une réduction de la période d'exercice des fonctions, et de nouvelles formes de financement. Le présent article analyse ces changements dans les universités, les collèges polytechniques et les écoles normales et décrit le rôle grandissant de l'Etat. Il s'efforce également d'en dégager les leçons pour d'autres systèmes éducatifs qui font face aux même pressions. Un glossaire d'abbréviations et d'acronymes apparaît à la page 301.

Revealing future research capacity from an analysis of a national database of discipline-coded Australian PhD thesis records

This article reports how statistical analyses of PhD thesis records can reveal future research capacities for disciplines beyond their primary fields. The previous research showed that most theses contributed to and/or used methodologies from more than one discipline. In Australia, there was a concern for declining mathematical teaching and research capacity. We decided to investigate the ‘hidden’ mathematics research capacity in PhDs outside of mathematics. Australian PhD records were re-coded with up to three fields. Records with mathematics as one of their codes were selected and analysed for their relationships to disciplines in their other codes. Triple-coding revealed ‘hidden’ mathematical research capacity that had previously been single-coded in another field had mathematics as one of their subsequent fields. Our findings have implications for policy and planning for mathematics in Australia, and multiple coding of PhD theses records enables analyses for other disciplines to be undertaken to show their research capacities.     

Analysis of instruction for critical thinking in distance learning materials

This paper discusses procedures for the analysis of instructional strategies incorporated into distance learning materials, especially with regard to the development of the higher order cognitive ability—critical thinking. It examines the function of task analysis as an integral part of the instructional design process, analysing three different approaches available to the instructional designer towards the analysis of tasks required of distance learners. Comparing the learning hierarchy, the concept hierarchy, and the information processing approaches, it was found that the latter was the only one suitable for this current study because of the requirement that critical thinking be linked with domain‐specific knowledge, rather than be learned as an independent ability. Different algorithms for both the student and the designer/analyst are included as part of the information processing approach, and, although these methods are yet to be validated, they seem to offer sufficient promise, while allowing the analyst to make further decisions during the analysis.     

Using Representations: Comprehension and Production of Actions with Imagined Objects

Previous research suggests that young children have difficulty producing actions with imagined objects (pantomimes): They frequently substitute a body part to represent the object involved in the action. This response has also been observed in neurologically impaired adults. Study 1 examined the comprehension and production of pantomimes in 3- and 5-year-old children and normal adults to explore further this aspect of representational ability. Results indicate that young children not only have difficulty producing imaginary object representations in contrast to normal adults, they also have difficulty comprehending imaginary object representations and are better at comprehending pantomimes with a body part representation. The results from the pantomime comprehension task were replicated in Study 2 with 3- and 4-year-olds. These findings are discussed in the context of the development of representational ability as children demonstrate increasing independence from concrete environmental support in their knowledge about actions.     

Research of technical knowledge and creativity development of children in pre-primary education through interactive whiteboard

The introduced study represents methodology and results of research focused on utilization of interactive whiteboard as didactic technology mediating information through multimedia worksheets applied in education process in pre-primary education. Its aim was to determine whether it can significantly increase the level of children’s acquired knowledge in the field of technical skills education and whether it can positively influence the development of children’s creative skills as a sign of their motivation. We observe that this issue in the way it is theoretically and practically established in this study can contribute by proposing education standards and set of multimedia worksheets in the technical field in Slovak pre-primary education.
