Validity of block start performance without arm forces or by kinematics-only methods

The purpose of this study was to validate the calculation of reaction time (RT) and normalised power in block starts without considering arm ground reaction forces (GRFs) or using two kinematics-only methods. The RT and normalised power in the action phase were calculated using four different methods: using GRFs of arms and legs by force plates (whole F-based method), which can be regarded as the most valid method, using GRFs of legs captured by force plates (legs F-based method), using position of the centre of mass of the entire body captured by high-speed cameras (whole P-based method), and using only a partial subset of segment position (partial P-based method). Bland–Altman plots demonstrated that the RT of the legs F-based method was not similar to that of the whole F-based method: the mean difference was 7.4 ms and the 95% limits of agreement was?45.1 to 59.8 ms, and it was the least valid method for the calculation among the four methods. In contrast, the normalised power was more valid in the legs F-based method, followed by whole and partial P-based methods. This information will help researchers and practitioners to decide upon their analysis methods when analysing block start performance.     

Situation-orientated recognition of tactical patterns in volleyball

One important factor for effective operations in team sports is the team tactical behaviour. Many suggestions about appropriate players' positions in different attack or defence situations have been made. The aims of this study were to develop a classification of offensive and defensive behaviours and to identify team-specific tactical patterns in international women's volleyball. Both the classification and identification of tactical patterns is done by means of a hierarchical cluster analysis. Clusters are formed on the basis of similarities in the players' positions on the court. Time continuous data of the movements, including the start and end points during a pass from the setter, are analysed. Results show team-specific patterns of defensive moves with assessment rates of up to 80%. Furthermore, the recognition of match situations illustrates a clear classification of attack and defence situations and even within different defence conditions (approximately 100%). Thus, this approach to team tactical analysis yields classifications of selected offensive and defensive strategies as well as an identification of tactical patterns of different national teams in standardized situations. The results lead us to question training concepts that assume a team-independent optimal strategy with respect to the players' positions in team sports.     

Audio-Visual Media in the Kindergarten

In October 1972 the sound of hammers could be heard in an isolated corner of the Library Complex at what was to become known as the Alvan Ikoku College of Education, Owerri. The area under construction was to be the new Micro–teaching Laboratory, fully equipped with the latest videotape equipment. In June, 1973, the Microteaching Laboratory was officially opened. The College was now prepared to undertake the development of a full scale microteaching programme.     

Foot strike patterns of recreational and sub-elite runners in a long-distance road race

Although the biomechanical properties of the various types of running foot strike (rearfoot, midfoot, and forefoot) have been studied extensively in the laboratory, only a few studies have attempted to quantify the frequency of running foot strike variants among runners in competitive road races. We classified the left and right foot strike patterns of 936 distance runners, most of whom would be considered of recreational or sub-elite ability, at the 10 km point of a half-marathon/marathon road race. We classified 88.9% of runners at the 10 km point as rearfoot strikers, 3.4% as midfoot strikers, 1.8% as forefoot strikers, and 5.9% of runners exhibited discrete foot strike asymmetry. Rearfoot striking was more common among our sample of mostly recreational distance runners than has been previously reported for samples of faster runners. We also compared foot strike patterns of 286 individual marathon runners between the 10 km and 32 km race locations and observed increased frequency of rearfoot striking at 32 km. A large percentage of runners switched from midfoot and forefoot foot strikes at 10 km to rearfoot strikes at 32 km. The frequency of discrete foot strike asymmetry declined from the 10 km to the 32 km location. Among marathon runners, we found no significant relationship between foot strike patterns and race times.     

Education for Democracy: reasons and strategies

According to social scientists Herfried Münkler in Germany and Colin Crouch in England, major developments in Western industrial societies — individualism, increasing social complexity, globalisation — present serious threats to basic requirements of stable societies and expose democracy to the corrosion of its socio-moral resources such as social trust and civic commitment to the public good. In order to grow and to flourish, the competences and capabilities that constitute these resources require systematic cultivation through educational processes.The school is the only institution that can provide the appropriate experience of a democratic life to all members of society. At present, however, schools are generally far from this goal. This article describes strategies for providing the experience of schools as democratic lifeworlds from an early age: classroom councils as tools for democratic self government and sites for sociomoral learning; projects of service learning in the community which can be successfully organized by these councils; and early experiences of civic engagement in community contexts as part of democratic classroom practice.     

Fifth graders metacognitive knowledge: general or domain-specific?

The purpose of the present study was to investigate the structure of metacognitive knowledge in fifth grade pupils and its relation to school achievement. Since the structure of metacognitive knowledge is controversially discussed with little empirical evidence for either its domain specificity or its domain transferability, the debate remains somewhat hypothetical up to date. In theory it is assumed that the development of metacognitive knowledge begins highly domain and situation-specific and becomes more flexible and domain-transcending with practice and experience (Borkowski et al. 2000). As standardized measures to assess metacognitive knowledge of students in the age group under investigation were missing, newly developed instruments were applied to assess the domain-specific metacognitive knowledge in reading and mathematics as well as domain-transcending metacognitive knowledge. The influences of domain-specific and general metacognitive knowledge on school achievement in the two domains were analyzed. While findings on the structure of metacognitive knowledge indicate some degree of domain specificity, they also point out a strong relation between general metacognitive knowledge and domain-specific metacognitive knowledge. The cross-sectional relation between metacognitive knowledge and academic achievement were relatively low. Implications for future research will be discussed.     

Teachers’ beliefs, instructional behaviors, and students’ engagement in learning from texts with instructional pictures

This study investigated the relations between teachers’ pedagogical beliefs and students’ self-reported engagement in learning from texts with instructional pictures. Participants were the biology, geography, and German teachers of 46 classes (Grades 5-8) and their students. Teachers’ instructional behaviors and students’ engagement in learning from texts with instructional pictures were assessed by means of student ratings. Teachers’ beliefs about using texts with instructional pictures in their teaching were assessed by a self-report questionnaire. Results showed that the more teachers believed that students should be taught clear strategies on how to learn from texts with instructional pictures the more engagement was reported by their students. A multilevel mediation model showed that the association between teachers’ beliefs and students’ self-reported engagement was mediated by teachers’ perceived instructional behavior.     

Discipline orientations of pre‐service teachers before and after student teaching

This study examined the classroom discipline orientations of pre‐service elementary teachers both before and after the student teaching experience. Prior to beginning and immediately after completing their full‐time student teaching experience, pre‐service teachers (N = 220) from three southeastern universities in the USA completed a discipline belief instrument which identified their preferred model of classroom discipline. The results showed that the student teaching experience significantly increased beginning teachers’ preferences toward a more assertive discipline model (Rules and Consequences) and decreased their preferences toward the humanistic discipline model (Relationship–Listening). These results demonstrate that the student teaching experience may be creating a dissonance in prior knowledge and beliefs, and experiences of pre‐service teachers in classrooms. The results of the study suggest that teacher education programs can help pre‐service teachers transition more smoothly into classroom teaching by providing a school–university partnership as well as more lessons and advice on handling specific classroom management situations.     

Student-Centered Practice in the 21st Century Community College

This article reflects how the student development theories of William Perry and Robert Kegan are useful in understanding the student behaviors in community and technical colleges. Leaders of these organizations must incorporate theory-based practices in order to promote a student-centered culture. Examples are given as illustrations of how community colleges can put student development theories into practice to facilitate student success in the 21st century.
