The Computer in Secondary Education

In this context we do not mean the production of educational films by various institutes, publishers, and professional film-makers because they have to follow a given standard in technique, theme and reference to the school curriculum.     

SOCIAL DETERMINANTS AND POTENTIALS OF EDUCATION IN LATER LIFE: THE CASE OF AUSTRIA

Various theoretical concepts such as plasticity, competence, and potential have recently been applied to underline the possibility of later‐life development and change. Value and limitations of these concepts are discussed in view of learning in later life. A review of the special case of Austria and the educational attainments of its elderly indicates that social reality is slow in its transformation and that the disadvantageous educational achievements credited to today's older people hardly encourage them in pursuing later‐life studies. The paper reports results obtained by means of two questionnaires filled out by older students and teachers. This empirical investigation examines the influence of societal norms, social setting in institution‐related learning situations (age‐homogeneity vs. age‐heterogeneity), and instructors’ attitudes toward older students. The results demonstrate that permanent education and proper stimulation of the learning processes depend on a complex relationship between (competent) individuals, their social surroundings, and learning conditions that often prove unfavorable.     

Effect of chainring ovality on joint power during cycling at different workloads and cadences

Non-circular chainrings theoretically enhance cycling performance by increasing effective chainring diameter and varying crank velocity, but research has failed to consistently reproduce the benefits in cycling trials. The aim of this study was (1) to investigate the effect of different chainring shapes on sagittal knee joint moment and sagittal lower limb joint powers and (2) to investigate whether alterations are affected by cadence and workload. Fourteen elite cyclists cycled in six conditions (70, 90 and 110 rpm, each at 180 and 300 W), for 2 min each, using three chainrings of different ovalities (1.0–1.215). Kinematic data and pedal forces were collected. For most conditions, only the chainring with the highest ovality (1.215) was characterised by smaller sagittal knee joint moments, smaller relative sagittal knee joint power contribution and larger relative sagittal hip joint power contribution, which suggests a change from maximising efficiency to maximising power production. Effect sizes increased with higher cadences, but not with higher workload. This study has application for athletes, clinicians and sports equipment industry as a non-circular chainring can change joint-specific power generation and decrease knee joint moment, but certain ovality seems to be necessary to provoke this effect.     

A New Two-Step Approach for Hands-On Teaching of Gene Technology: Effects on Students’ Activities During Experimentation in an Outreach Gene Technology Lab

Emphasis on improving higher level biology education continues. A new two-step approach to the experimental phases within an outreach gene technology lab, derived from cognitive load theory, is presented. We compared our approach using a quasi-experimental design with the conventional one-step mode. The difference consisted of additional focused discussions combined with students writing down their ideas (step one) prior to starting any experimental procedure (step two). We monitored students’ activities during the experimental phases by continuously videotaping 20 work groups within each approach (N = 131). Subsequent classification of students’ activities yielded 10 categories (with well-fitting intra- and inter-observer scores with respect to reliability). Based on the students’ individual time budgets, we evaluated students’ roles during experimentation from their prevalent activities (by independently using two cluster analysis methods). Independently of the approach, two common clusters emerged, which we labeled as ‘all-rounders’ and as ‘passive students’, and two clusters specific to each approach: ‘observers’ as well as ‘high-experimenters’ were identified only within the one-step approach whereas under the two-step conditions ‘managers’ and ‘scribes’ were identified. Potential changes in group-leadership style during experimentation are discussed, and conclusions for optimizing science teaching are drawn.

Analyse und Förderung effektiver Lehr-Lernprozesse unter dem Anspruch evidenzbasierter Bildungsreform

The performance of education systems is significantly influenced by the quality of teaching/learning processes. On the basis of empirical research, the programme for evidence-based educational research also contributes to improving the quality of teaching/learning processes. Hereby, new requirements for the insight of educational research as well as for the accelerated transfer of research findings into politics and practice have been formulated. Currently, the programme is strongly criticised by political and scientific stakeholders with regard to both its desirability and its feasibility. This report traces the debate on evidence-based educational reforms, systematically outlines the central topics of discussion, and views the current state of research on the contribution of empirical educational research to political and practical reforms. Particular attention is paid to the effects on teaching/learning processes.
