Search for the roots of ratio: Some thoughts on the long term learning process (towards ... a theory)

According to the view of several experts which have been reported in part I, (Streefland, 1984) ratio requires a long term learning process. In the present part features and tools to outline and shape the longer term learning process for ratio are exhibited and elucidated by examples. Particularly instigating ratio-anticipating activities and creating visual models and schemes. The search for sources of the concept of ratio results in what might be called germs for a theory of teaching and learning ratio.     

Changes in cultural representations on Indonesian children's television from the 1980s to the 2000s

This study describes the changes over time in the portrayal of socio-cultural characteristics; namely gender, age, ethnicity, religious outlook, family unit, violence experienced, living conditions, and cultural values in Indonesian children's television programs. Using systematic-quantitative content analysis of popular locally produced Indonesian children's television programs in the 1980s and the 2000s, this study found that all socio-cultural characteristics changed over time, except for gender representation with male actors consistently outnumbering female actors. There were some predominant socio-cultural characteristics in the 1980s, the era of authoritarian broadcasting system in Indonesia: most of the major characters were children and preteens, from Western Indonesia, not showing religious symbols or practices, having more than one sibling, and the majority of the adult characters were married. In the 2000s, the era of liberal broadcasting system, major characters were children and teens, showing certain religious symbols, having no or only one sibling, and the majority of the adult characters were single. Indonesian children's television brought certain cultural values to the fore for their young audiences to identify themselves with: self-direction and benevolence.     

Different combinations of perceived autonomy support and control: identifying the most optimal motivating style

Background: According to Self-Determination Theory, teachers and sport coaches can differ in the motivating style they rely upon to motivate young people. When endorsing an autonomy-supportive motivating style, instructors try to identify, vitalize, and nurture youngsters’ inner motivational resources. In contrast, instructors with a dominant controlling motivating style rather pressure youngsters to think, feel, or behave in prescribed ways. While the dimensions of autonomy support and control can be conceptually differentiated, in reality both dimensions may co-occur to different degrees.

Purpose: The present study investigates to what extent perceived autonomy support and control can be combined and which motivating style then yields the most optimal pattern of outcomes.

Research design: Multi-Study with Cross-Sectional Design.

Findings: In two studies, conducted among elite athletes (N?=?202; M_age?=?15.63; SD?=?1.70) and students in physical education (N?=?647; M_age?=?13.27; SD?=?0.68) reporting on their instructor’s motivating style, cluster analyses systematically pointed towards the extraction of four motivating profiles. Two of these groups were characterized by the dominant presence of either autonomy support (i.e. high-autonomy support) or control (i.e. high control), while the two dimensions were found to be equally present in the two remaining groups (i.e. high–high or low–low). Results revealed that the high-autonomy support group showed to the most optimal pattern of outcomes (e.g. need satisfaction, autonomous motivation), while the high-control group yielded the least optimal pattern of outcomes. Results further showed that perceiving one’s instructor as high on control is detrimental (e.g. higher need frustration, amotivation) even when the instructor is additionally perceived to be autonomy-supportive. Finally, it appeared better to be relatively uninvolved than to be perceived as exclusively high on control.

Conclusions: When coaches or teachers are perceived to be high on autonomy support and low on control, this is likely to benefit youngsters’ motivation and well-being. Also, while some instructors, particularly those who are functioning in a more competitive context where pressure is considered more normative, may endorse the belief that the combination of autonomy support and control yields the most effective cocktail to motivate young people (e.g. using competitive and game-based activities to make it fun, while treating ‘the losers’ with punishments such as push-ups or humiliating comments), this perspective is not supported by the findings of the current study. Apart, from its theoretical relevance, the findings of the present study are valuable for future intervention development.     

Begin-of-school-year perceived autonomy-support and structure as predictors of end-of-school-year study efforts and procrastination: the mediating role of autonomous and controlled motivation

In this prospective study, we recruited a sample of Belgian adolescents (N = 886) to investigate to what extent perceived teachers’ motivating style relates to quality of motivation in the beginning of the school year and, in turn, changes in study effort and procrastination by the end of the school year. After controlling for initial levels of study effort and procrastination and for a shared variance due to classroom membership, we found, through path analysis, perceived autonomy support and structure to relate positively to autonomous motivation, which in turn predicted increased study effort and decreased procrastination at the end of the school year. The findings are discussed from a theoretical and practical standpoint.     

Development and optimization of an injury prevention intervention for physical education teachers

Background: Injury prevention is highly needed in physically active populations, such as pre-service and in-service physical education teachers (PETs). As a lack of adherence to preventive strategies is problematic in injury, it seems crucial to develop and optimize interventions that correspond to the specific needs and wishes of PETs.

Aim: The purpose of the present study was fourfold. Specifically, we aimed at (1) systematically optimizing an injury prevention intervention for PETs, based on teachers’ qualitative evaluation of the intervention, (2) quantitatively investigating whether the appreciation of the injury prevention intervention was higher after optimization, (3) examining whether participation in the intervention resulted in positive changes in teachers’ perceived utility of, and confidence to apply the proposed preventive strategies, as well as their knowledge about these strategies, and (4) describing teachers’ adherence to the proposed preventive strategies while they were engaging in the intervention.

Participants: Twenty PETs (13 men, Mage = 42.1 ± 12.17 years) from nine different secondary schools in Flanders (Belgium) voluntarily participated in this study. The intervention, based on findings from the continuing professional development (CPD) literature, and the principles of the self-determination theory, took place on two different training days (Training A and Training B) and consisted of seven intrinsic injury prevention strategies.

Data collection and analysis: Qualitative data on teachers’ appreciation of the intervention were collected by means of focus group interviews, which were used to optimize the intervention (Aim 1). Quantitative data on teachers’ appreciation were collected directly after they had engaged in the intervention and were used to compare the appreciation from the initial to more optimized versions of the trainings (Aim 2). Further, by means of repeated measures ANOVAs positive evolutions in teachers’ belief in the utility of, confidence to apply and knowledge about the provided strategies across time were examined (Aim 3). Finally, teachers’ adherence was evaluated by relying on weekly online registrations of minutes and types of preventive strategies teachers had practised during the past week (Aim 4).

Findings: Despite the relatively high initial appreciation scores (4.2 out of 5), the optimized versions of the trainings scored better on interaction, intelligibility, innovation, practical usefulness, and recommendation (Aims 1 and 2). Significant differences were found over time in terms of within-teacher changes in perceived utility of (4.05–4.73–4.48; p?p?p?Conclusions: The present study developed an intervention that optimally fulfils the wishes and needs of the target population, namely PETs, and can readily be implemented in PET education programmes or CPD programmes for in-service PETs. Results of this pilot study are promising because teachers displayed increases in several relevant outcomes. Various suggestions are formulated on how to increase PETs’ appreciation of CPD programmes.     

Musculoskeletal injuries in physical education versus non-physical education teachers: a prospective study

Physical education (PE) teachers have a physically demanding job, putting them at a considerable risk for musculoskeletal injuries. To structurally develop tailored injury prevention programmes for PE teachers, a clear understanding of the extent, characteristics and underlying factors of their musculoskeletal injuries compared to referents is necessary. Therefore, the current study prospectively followed 103 PE teachers and 58 non-PE teachers, who registered musculoskeletal injuries and time of exposure to sports participation during one school year. Pearson χ²-tests and independent samples t-tests determined significant differences between PE and non-PE teachers regarding demographics and variables possibly related to injury occurrence. PE teachers had 1.23 and non-PE teachers 0.78 injuries/teacher/school year. This difference was significantly different after adjustment for hours spent weekly on intracurricular teaching during the career and for injury history during the preceding six months (P = 0.009; OR = 0.511; 95% CI = 0.308–0.846). PE teachers’ most affected body parts were the knee and the back. PE teachers had a more extensive injury history (P < 0.001), a higher work- (P < 0.001) and sport index (P < 0.001), practiced more sports (P < 0.002) and taught more extracurricular sports (P = 0.001). Future injury prevention programmes should take account for the great injury history and heavy physical load in PE teachers.     

Mind maps as primers when reading-for-learning in elementary grades? An eye tracking study

Mind maps are often used to help readers process texts, but their effectiveness is empirically under-investigated. This study explores whether the use of mind maps presented either before or after the text can prime successful selective processing strategies related to the text topic structure. Differences in performance outcomes (i.e., memory and comprehension) are also investigated. Sixty-four late elementary education students were randomly assigned to a text-only-condition (T), mind map-text-condition (MMT) or text-mind map-condition (TMM). All groups studied an informative text while their eye movements were registered. Multilayered posttests and interviews were administered. Linear mixed effect models and one-way analysis of variances show that presenting a mind map beforehand primes more successful selective processing strategies than when the mind map is presented afterwards or not presented. In contrast, the TMM-condition outperformed the others in their amount of free recall and coherence. This study suggests that both receiving a mind map before or after text processing can be beneficial during targeted instruction in view of successful reading-for-learning.

     

A Systematic Review on the Conceptualization and Operationalization of Students' Levels of Processing in Functional Magnetic Resonance Imaging Studies

In educational research, there is a growing interest in functional magnetic resonance imaging (fMRI) to examine students' levels of processing. As there is a growing interest in the use of fMRI, a systematic review was conducted to examine how deep and surface levels of processing are operationalized within the neuroscientific field. In addition, we investigated how this operationalization impacts on the conceptualization of levels of processing within fMRI research. A systematic search was conducted within the MEDLINE, PubMed, ERIC, and Web of Science databases, and 25 studies were identified for this review. With regard to the operationalization, the review indicates that levels of processing were examined under highly controlled conditions with decontextualized and simplified language stimuli. Analysis of these studies revealed that there is a lack of conceptual clarity as, in half of the cases, no theoretical framework was explicitly mentioned, and no clear definition was given regarding levels of processing.     

Promoting elementary school students' autonomous reading motivation: Effects of a teacher professional development workshop

Responding to the declining trend in reading motivation in and beyond the elementary school years, the authors aimed to enhance late-elementary school students' autonomous reading motivation. Toward this end, the authors evaluated the influence of a teacher professional development grounded in self-determination theory on fifth-grade students' (n = 664) autonomous motivation for in-school and leisure-time reading. A quasi-experimental repeated measures design was set up with experimental and control conditions. The experimental condition consisted of teachers participating in a professional development workshop aimed at providing the knowledge and skills necessary to implement an autonomy-supportive and structuring teaching style, whereas the control condition included teachers who continued with their current teaching repertoire. Multilevel piece-wise growth analyses corroborated that students in the experimental group reported increased recreational autonomous reading motivation from pretest to posttest relative to the control group. Additional analyses made clear that boys in particular benefitted from their teachers' professional development.
