Twenty-four-hour movement behaviours and fundamental movement skills in preschool children: A compositional and isotemporal substitution analysis

ABSTRACT

Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r² = 0.31), object control (r² = 0.19), and total motor score (r² = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood.     

Pre-service teachers' use of problem-solving in primary science

The use of problem-solving in science instruction implies a change in the teacher's role from dispensing content information to encouraging critical reflective thinking in the student. For problem-solving to become an integral part of the science curriculum, teachers must make it the focus of their instruction. This study investigated the extent to which pre-service primary teachers used the problem-solving approach in their science instruction. It also identified the factors affecting their efforts to teach science using this approach. The issues considered are important in whether problem-solving becomes part of the science curriculum, as teaching behaviour influences student learning outcomes.

Teacher professional development: Which aspects of inservice do teachers believe influence their classroom practice?

Research into teacher inservice in primary science generally focuses on evaluating the objectives of each program in terms of the immediate outcomes. Little research appears to have been conducted into the long term effects of interactive inservice programs on the classroom practice of the participants. During 1993 the long term effects of participation in the Primary Science/Technology Project (Sci-Tec), as perceived by the teacher participants, were investigated. Focus teachers who had participated in Sci-Tec between 1988–1991 were asked to provide information about their current science teaching practice, and about the influence that Sci-Tec had had on their current practice. Six of these teachers were then interviewed to determine which specific aspects of the project they believed had most influenced the development of their current classroom practice in teaching science.

Development of an instrument for measuring attitudes of early childhood educators towards science

The attitude towards science of first year early childhood education students was explored using an instrument developed for the purpose. The instrument comprises four Likert-type scales, biographical items and two open-ended attitude items. The four scales, characterised as ‘confidence’, ‘enjoyment’, ‘usefulness’ and ‘appropriateness of science for young children’, were supported by varimax factor analysis and had reliabilities from 0.83 to 0.88. Use of the combined scales as a general ‘attitude towards science’ scale was supported by principal components analysis; reliability for the combined scale was 0.94. Comments made in response to the open-ended items supported the validity of the scales. For the student group as a whole, mean scores on all scales were slightly to moderately positive, with the highest mean being for the ‘science for young children’ scale. Students who had studied at least one science subject at Year 12 level had significantly higher scores on all scales than students who had not studied science at senior level.

Formative Interventions for Expansive Learning and Transformative Agency

This article examines formative interventions as we understand them in cultural-historical activity theory and reflects on key differences between this intervention research tradition and design-based research as it is conceived in the learning sciences tradition. Three projects, including 2 Change Laboratories, are analyzed with the help of conceptual lenses derived from basic epistemological principles for intervention research in activity theory. In all 3 interventions, learners expansively transformed the object of their activity. The Change Laboratory cases, however, show that this learning process included productive deviations from the researchers’ instructional intentions, leading to significant outcomes, both practical and theoretical, that were not anticipated by the interventionists. Together these cases illustrate that an activity-theoretical formative intervention approach differs from design-based research in the following ways: (a) formative interventions are based on design done by the learners; (b) the collective design effort is seen as part of an expansive learning process including participatory analyses and implementation phases; (c) rather than aiming at transferable and scalable solutions, formative interventions aim at generative solutions developing over lengthy periods of time both in the researched activities and in the research community.     

Educational technology as a key to educational innovation:

Instructional technology, especially the use of computers and the Internet has been lagging behind in the German educational system in comparison to other European countries. When this lack was realized in the second half of the 1990s it had quite a “shock-effect” but one of the healthy kind: Since then numerous public and private initiatives have been started to advance the use of technology in schools, higher education, and in vocational training. At the college and university level, there is a trend towards connecting online and offline courses. Also, it was understood that it is not enough to just provide schools and universities with the technology needed but that the introduction of technology has to be accompanied by profound systemic and structural changes. Thus, there is great hope that the use of technology in education will fuel educational innovations at all levels needed for educating and training pupils and students to act as responsible and media-literate citizens in a modern world.
