Epistemology,situated cognition,and mental models: 'Like a bridge over troubled water'

Over the past two decades important educational implications have beendrawn mainly from two movements of epistemology: Constructivismand situated cognition. Aside from a meta-theoretical use ofconstructivism, the concept 'situated cognition' refers to a conceptionof situational context bound to a historically and socially determinedsituational logic. Focusing on educational processes, situated cognitionis considered to be a central construct for instruction, as is theclosely related concept of the construction of mental models.There are various kinds of the construction and change of mental modelsin a situational context: self-guided inductive construction is oneexample; another is the processing of a conceptual model providedto the learner. An emerging question is how the preconception changesand if the effects of such a model transition are stable. An exploratorystudy will be sketched which investigates the significance of aconceptual model provided at the beginning of the learning process;it has been hypothesized, that such a conceptual model significantlyimpacts the stability (i.e. the successful reconstruction) of mentalmodels built in the course of learning. Also considerableintraindividual differences and changes between two points of assessingthe learners' causal explanations were found. Similarities of theindividuals' reconstructions could be explained with regard tosimilarities of the structures of the learning situations and therelated instructional intervention. In general, the results of thisexploratory study support the assumption that mental models areconstructed in dependence on the demands of learning situations.     

A longitudinal perspective on inductive reasoning tasks. Illuminating the probability of change

Cognitive scientists have studied internal cognitive structures, processes, and systems for decades in order to understand how they function in human learning. Nevertheless, questions concerning the diagnosis of changes in these cognitive structures while solving inductive reasoning tasks are still being scrutinized. This paper reports findings from an experimental study in which 64 participants in three experimental groups solved tasks at ten measurement points. We were able to illuminate changes of cognitive structures and found significant differences between the treatments. The results also indicate that supportive information is an important aid for developing cognitive structures while solving inductive reasoning tasks.     

Die schulpraktische Ausbildung im Rahmen der Lehrerausbildung an den Österreichischen Universitäten

In the course of the fundamental reform of studies at the Austrian universities the education of grammar school teachers was renewed in 1971. In a long tradition (since 1855) teachers for upper secondary education, especially for grammar schools (which lead pupils to the matriculation qualification for university education) were prepared for their teacher admission examination by studies at the universities which comprised besides of subject matters theoretically introducing courses in pedagogy and psychology. Their practical training was organised in a guided probationary year at schools (apprenticeship‐type).

Since 1982 a new integrated (concurrent) preservice teacher education programme is realised at the Austrian universities, which combines subject studies (in two fields) with teachers’ professional preparation (comprising theoretical studies and practical activities and experiences in education and teaching). The new teacher education programme takes 4#fr1/2> years and leads to the academic degree of a master of arts or science, which gives full professional teacher qualification. The profession‐oriented parts include studies in education and psychology (10 semester course units: 150 hours), subject teaching studies (12‐24 semesters course units: 180‐360 hours) and a 12‐week period of practical teaching experience. Each university designs within this framework a specific study programme. An overview is given in the paper; the programme of the university of Graz is shown in more detail as an example.

At present the introduction of a one‐year‐lasting induction period as a second phase of teacher education is discussed and planned, which should be established in 1988‐89.
