Relationships between computational thinking and the quality of computer programs

Assessment criteria for competency-based education: a study in nursing education

This study examined the effects of type of assessment criteria (performance-based vs. competency-based), the relevance of assessment criteria (relevant criteria vs. all criteria), and their interaction on secondary vocational education students’ performance and assessment skills. Students on three programmes in the domain of nursing and care (N = 93) participated in the study. Results show that students who were given the relevant criteria made more accurate assessments of an expert model, performed better on a test and achieved higher instructional efficiency (defined as the relationship between performance and mental effort) compared to students who were given all criteria. Students who were given performance-based assessment criteria made more accurate assessments of an expert model and scored higher on task performance during practice compared to students who were given competency-based assessment criteria. They invested less mental effort in the assessments, resulting in higher instructional efficiency. An interaction effect for the concreteness of answers shows that the combination of performance-based and relevant criteria leads to superior analysis of worked examples compared to the other combinations of criteria.     

Boys: Getting it right: The ‘New’ disadvantaged or ‘disadvantage’ redefined?

Over recent years there has been widespread concern for masculinity and the education of boys in Australia. In the policy arena, this has involved a federal parliamentary inquiry into the education of boys (Boys: Getting it Right: Report on the inquiry into the education of boys, October 2002) and a federal government response to this inquiry (June 2003). This was followed by a review of the current education policy directed at gender, the Gender Equity Framework, and the development of strategies to increase the number of men going into teacher training. The way in whichGetting it Right and the federal government talk about boys and disadvantage is important. This paper argues that there is a particular understanding of disadvantage at work in this policy arena. It is an understanding of disadvantage extracted from a wider gendered power order.     

Training for reflective expertise: A four-component instructional design model for complex cognitive skills

This article presents a four-component instructional design model for the training of complex cognitive skills. In the analysis phase, the skill is decomposed into a set of recurrent skills that remain consistent over problem situations and a set of nonrecurrent skills that require variable performance over situations. In the design phase, two components relate to the design of practice; they pertain to the conditions under which practice leads either to rule automation during the performance of recurrent skills or to schema acquisition during the performance of nonrecurrent skills. The other two components relate to the design of information presentation; they pertain to the presentation of information that supports the performance of either recurrent or nonrecurrent skills. The basic prediction of the model is that its application leads to “reflective expertise” and increased performance on transfer tasks. Applications of the model that support this prediction are briefly discussed for the training of fault management in process industry, computer programming, and statistical analysis.     

Process-Oriented Worked Examples: Improving Transfer Performance Through Enhanced Understanding

The research on worked examples has shown thatfor novices, studying worked examples is oftena more effective and efficient way of learningthan solving conventional problems. Thistheoretical paper argues that addingprocess-oriented information to worked examplescan further enhance transfer performance,especially for complex cognitive skills withmultiple possible solution paths.Process-oriented information refers to theprincipled (``why'') and strategic (``how'')information that experts use when solvingproblems. From a cognitive load perspective,studying the expert's ``why'' and ``how''information can be seen as constituting agermane cognitive load, which can fosterstudents' understanding of the principles of adomain and the rationale behind the selectedoperators, and their knowledge about howexperts select a strategy, respectively. Issueswith regard to the design, implementation, andassessment of effects of process-orientedworked examples are discussed, as well as thequestions they raise for future research.     

Facebook class groups of high school students: their role in establishing social dynamics and learning experiences

The study’s main aim was to explore the role of Facebook class groups, created and managed by high-school students, in facilitating social dynamics and learning experiences. Fourteen Facebook class groups were observed online and students were subsequently questioned through focus-group interviews. Our findings show that Facebook class groups can promote both bonding and learning. Bonding can be enhanced because Facebook class groups foster a sense of solidarity and unity among students. Also, Facebook can stimulate (social) learning because students gain more insights in the subject matter and are challenged to carry out an evaluation of their own study methods and progress. Therefore, drawing on the theories of seamless learning and affinity spaces, we conclude that Facebook class groups are important for social affiliation and effective learning.

     

Walking the tightrope with an e-portfolio: imbalance between support and autonomy hampers self-directed learning

Teacher coaching is essential to support self-directed learning, but requires a lot of time and energy. This mixed-methods study investigated the effects of using an e-portfolio with a self-coaching protocol and limited teacher coaching on the development of self-directed learning skills and motivation. With regard to self-directed learning, students’ overestimation of performance on learning tasks grew over time, while their ability to formulate points for improvement did not change significantly. With regard to motivation, students’ controlled (i.e. largely extrinsic) motivation increased while their autonomous (i.e. largely intrinsic) motivation decreased. Thematic analysis of interviews demonstrated students needed more support and feedback from their teacher. The use of suboptimal cues for performance assessment and an imperfect balance between autonomy and support hampered self-directed learning and motivation. We recommend providing just-in-time feedback about performance on learning tasks and giving students some autonomy over the choice of learning tasks, to enhance reflection and motivation.     

Socio‐economic background,parental involvement and teacher perceptions of these in relation to pupil achievement

Parental involvement and teacher perceptions of parental involvement in the education of children were studied in relation to level of parental education and pupil achievement. A questionnaire was administered to 218 parents and 60 teachers. Correlational analyses and paired‐sample analyses showed teacher perceptions to be weakly related to parental reports of their own involvement and to operate at a different level. Regression analyses and analyses of variance showed teacher perceptions of parental involvement to affect pupil achievement more strongly than parental reports. The results suggest that teacher perceptions of parents may be stereotyped and that such stereotypes can clearly affect academic results.     

Back to the future: A methodology for comparing old A-level and new AS standards

Curriculum 2000 has meant significant change for the post-16 sector. New qualifications have been introduced (e.g. the new Advanced Subsidiary examination) and the number of students involved in education and training post-16 has increased. In this scenario how can the standards of new qualifications, particularly the new Advanced Subsidiary examinations, be compared with those of previous qualifications? One method is to use the prior achievement of candidates (i.e. GCSE results) as a basis for comparison of their results on subsequent qualifications (i.e. A levels and AS). This method of comparability and its limitations will be explored using examples with actual data.
