Student Learning Through Participation in Inquiry Activities: Two Case Studies in Teacher and Computer Engineering Education

The two case studies reported in this article contribute to a better understanding of how inquiry tasks and activities are employed as resourceful means for learning in higher professional education. An observation-based approach was used to explore characteristics of and challenges in students’ participation in collaborative inquiry activities in two first-year introductory courses in teacher and computer engineering education. The findings highlight that the students’ activities varied with regard to focus and structure and were shaped by the types of inquiry tasks, i.e. case analysis and project-based work, by how the inquiry process was guided and supported and the way the domain-specific knowledge resources and practices were introduced. An exploratory strategy and rather confined use of resources characterised the teacher education students’ inquiry, while collaborative programming, a trial-and-error approach and extensive use of external resources that of the engineering education students’. For the teacher students, the main challenge was to construct meaning of conceptual knowledge and to integrate different forms of knowledge as a lens for analysing practice. The computer engineering students experienced challenges with unpacking the underlying principles and knowledge black-boxed in the widely available resources. The article suggests that future research and curriculum designs should depart from a more refined understanding of inquiry as a learning means, by connecting inquiry activities to the specific knowledge domains, the type of tasks most suited to explore each of this domains and the challenges that may arise for students.

Improving Prospective Teachers’ Counseling Competence in Parent-Teacher Talks: Effects of Training and Feedback

Counseling parents concerning students’ learning processes is considered to be an increasingly important competence area of teachers. However, few educational programs exist specifically focusing on improving this essential teacher competence, particularly in early teacher education. The current study, which took place at a German university, describes the evaluation of a corresponding training program for prospective teachers as well as a process-oriented feedback intervention. We conducted a quasi-experimental study with three treatment groups (training group, training + feedback group, control group) combining pre-, post-, and follow-up test measures with time–series data. By means of multivariate repeated measures MANOVAs and time-series analyses, we were able to demonstrate that prospective teachers’ counseling competence can be successfully fostered by training and individual process-oriented feedback. Our results provide several practical implications concerning the improvement of teachers’ counseling competence within the context of teacher education.     

Comparative analysis of delayed alternation learning in cats,mice, and guinea pigs

The performance of cats, guinea pigs, and mice in a delayed alternation paradigm was compared both during initial learning and following a 10-day retention interval. The testing situation (a modified T-maze), the length of the delay period (10 sec), and the amount of training per session and per week were kept identical for all three species. The results indicated that (1) animals of all three species acquired the task within similar time spans, (2) a considerable variance was apparent in the performance of individual animals independent of their species, and (3) guinea pigs, as a group, appeared to need a somewhat longer time to acquire delayed alternation than did mice and cats. Relearning of the task following the 10-day interval seemed to follow similar laws in all three species.     

Understanding teachers’ professional learning goals from their current professional concerns

In the day-to-day workplace teachers direct their own learning, but little is known about what drives their decisions about what they would like to learn. These decisions are assumed to be influenced by teachers’ current professional concerns. Also, teachers in different professional life phases have different reasons for engaging in professional learning. In this study, we explored the professional concerns underlying teachers’ learning goals in order to understand variation in professional learning over a teacher’s career. In this qualitative study, we administered a semi-structured interview and a card sorting task to 15 secondary school teachers to elicit teachers’ learning goals and current professional concerns. By conceptually combining teachers’ learning goals with professional concerns in concern-goal pairs, we sought to understand the different reasons for teachers’ learning. These concern-goal pairs were characterized in three different types of reasons: continuous, growth and improvement, and work-management. The results showed that early career teachers have mainly growth and improvement concerns, whereas mid- and late-career teachers have both continuous and growth and improvement concerns. Work-management concerns differ for early- and late-career teachers. Results are further discussed in terms of professional life phase models and teachers’ developmental tasks throughout their career.     

Definitions of bullying: a comparison of terms used,and age and gender differences,in a fourteen-country international comparison

The study of school bullying has recently assumed an international dimension, but is faced with difficulties in finding terms in different languages to correspond to the English word bullying. To investigate the meanings given to various terms, a set of 25 stick-figure cartoons was devised, covering a range of social situations between peers. These cartoons were shown to samples of 8- and 14-year-old pupils (N = 1,245; n = 604 at 8 years, n = 641 at 14 years) in schools in 14 different countries, who judged whether various native terms cognate to bullying, applied to them. Terms from 10 Indo-European languages and three Asian languages were sampled. Multidimensional scaling showed that 8-year-olds primarily discriminated nonaggressive and aggressive cartoon situations; however, 14-year-olds discriminated fighting from physical bullying, and also discriminated verbal bullying and social exclusion. Gender differences were less appreciable than age differences. Based on the 14-year-old data, profiles of 67 words were then constructed across the five major cartoon clusters. The main types of terms used fell into six groups: bullying (of all kinds), verbal plus physical bullying, solely verbal bullying, social exclusion, solely physical aggression, and mainly physical aggression. The findings are discussed in relation to developmental trends in how children understand bullying, the inferences that can be made from cross-national studies, and the design of such studies.     

Knowledge practices and relations in professional education

ABSTRACT

The dynamics of knowledge in society have transformed the conditions of professional work and learning. Professional expertise has become increasingly specialised, and practitioners are challenged to keep up with rapid developments in their fields. At the same time, the complexity of professional work requires the integration of different forms of knowledge and knowing. Against this background, the knowledge settings in which learners engage and the practices and resources these offer are of vital importance. This article addresses professional education as embedded in profession-specific ‘machineries of knowledge construction’, that is, the set of practices and arrangements through which knowledge and ways of knowing in a profession are generated. It is argued that such machineries span settings in education and work. Examples from research in three professional programmes are used to discuss how students are introduced to epistemic practices and resources in selected knowledge settings. Analytical attention is given to the dynamic interplay between people, practices, knowledge resources and educational arrangements as well as to how connections to work and the epistemic machinery are made. Taking these linkages into account is important for our understanding of what learning entails in different areas of expertise and how this may change over time.     

Understanding perspectives and emotions in contract violation: development of deontic and moral reasoning

Children between the ages of 3 and 10 years were presented with a set of pictures representing a contract with bilateral cheating options between a parent and child (Study 1) and between 2 peers (Study 2). The children had to (a) evaluate which situations violated the contract when the relevant information was presented, (b) anticipate the feelings of the violator and the victim, and (c) infer possible contract violation from 2 different perspectives when relevant information was covered. Results show that logical inferences about contract violation differ according to the type of task. Negative feelings attributed to the violator were dependent on age and type of relationship, revealing a content-sensitive codevelopment of cognitive abilities and moral reasoning in young children.
