THE CONCEPT OF PHILOSOPHICAL EDUCATION

Strangely, the concept of philosophical education is not much in use, at least not as a philosophical concept. In this essay, Steinar Bøyum attempts to outline such a philosophical concept of philosophical education. Bøyum uses Plato's Allegory of the Cave, René Descartes's life of doubt, and Immanuel Kant's criticism of metaphysics as paradigms or defining examples of this concept. Bøyum's aim in this essay is not exegetical; rather, he hopes to describe these examples in a way that will let their character as conceptions of philosophical education show forth. His underlying aims are to show which forms such conceptions may take and why philosophical education is or should be an important topic for both philosophy and education.     

The Use of ICT Tools in Mathematics: A Case-control Study of Best Practice in 9th Grade Classrooms

Results are reported from a study in which teachers' views of highly achieving ninth grade classes in Norway (KappAbel national competition winners) were compared with teachers' views of average achievement classes with regard to the use of information and communication technologies (ICT) and pedagogical practices. The main purpose of the study was to answer the following questions: What differential role does ICT play in the two kinds of classes as it relates to learning performance in mathematics, and how does the use of ICT relate to teachers' reported views and pedagogical practices? The key findings of the study are the following: First, KappAbel teachers were more likely to have studied math at universities whereas the control teachers were more likely to have studied at colleges. Second, KappAbel teachers were more likely to emphasize reasoning-oriented as compared with instrumental- or rule-oriented teaching of mathematics. Third, KappAbel teachers do perceive weaker general effects of ICT in relation to learning than control teachers; however subject specific ICT tools like spreadsheets are more used for purposes of exploration and research than in control classes. It is the teacher-guided student activity that makes the difference.     

Imitation jumps in ski jumping: Technical execution and relationship to performance level

ABSTRACT

Imitation jumps are frequently used in training for ski jumping. Yet, the dynamics of these jumps differ considerably. Thus, the relevance of imitation jumps for ski jumping performance is not elucidated. The aim of this study was to investigate the relationship between the technical execution of imitation jumps and ski jumping performance level. We compared the imitation jumps of 11 ski jumpers of different performance levels using a Spearman correlation transform of time traces of the kinetics (measured using force cells and motion capture) of imitation jumps. The kinetic aspects that were related to performance centred on the moment arm of ground reaction force to the centre of mass before the onset of the push-off, angular momentum early in push-off, thigh angle during the main period of push-off and vertical velocity towards the end of push-off. We propose that the thigh angle may be a key element allowing high development of linear momentum while preparing for appropriate aerodynamic position. Furthermore, the findings suggest that the kinetic development prior to (and during) push-off is more important than the kinematic end state at take-off.     

How do elite ski jumpers handle the dynamic conditions in imitation jumps?

We examined the effect of boundary conditions in imitation ski jumping on movement dynamics and coordination. We compared imitation ski jumps with – and without – the possibility to generate shear propulsion forces. Six elite ski jumpers performed imitation jumps by jumping from a fixed surface and from a rolling platform. The ground reaction force vector, kinematics of body segments, and EMG of eight lower limb muscles were recorded. Net joint dynamics were calculated using inverse dynamics. The two imitation jumps differed considerably from each other with regard to the dynamics (moments, forces), whereas the kinematics were very similar. Knee power was higher and hip power was lower on the rolling platform than on the fixed surface. Mean EMG levels were very similar for both conditions, but differences in the development of muscle activity were indicated for seven of eight muscles. These differences are reflected in a subtle difference of the alignment of ground reaction force with centre of mass: the ground reaction force runs continuously close to but behind the centre of mass on the rolling platform and fluctuates around it on the fixed surface. This likely reflects a different strategy for controlling angular momentum.     

Fairness in education – a normative analysis of OECD policy documents

Educational policy depends on assumptions about fairness in education, whether they are made explicit or kept implicit. Without a view of fairness, one would be in the dark as to what should be done about the reproduction of social inequality through education, or whether or not anything should be done at all. The aim of this paper is to uncover the view of fairness in Organisation for Economic Co-operation and Development (OECD) education policy. It is based on an analysis of the normative argumentation concerning educational fairness in a set of policy documents from the last seven years, with special emphasis on the association between social background and educational achievement. The main result of the analysis is that the OECD explicitly operate with a loose idea of equal opportunity, compatible with even a merely formal equality, but implicitly with a meritocratic variant of fair equality of opportunity. In the final section, I argue that the OECD approach to fairness suffers from a limitation in that it considers educational justice in isolation from social justice in general.     

Frequency range size and the frequency range constraint in auditory perception by European starlings (Sturnus vulgaris)

We report data bearing on the ability of European starlings to generalize a serial auditory pitch pattern discrimination from one frequency range to another. In earlier research (e.g., Hulse & Cyrix, 1985), European starlings failed to generalize such a discrimination from one 1-octave range of frequencies to another 1-octave range above or below the initial training range. The starlings thus demonstrated a hitherto unknown phenomenon, thefrequency range constraint. In the present research, we first explored the frequency limits over which the range constraint might hold. The constraint was obtained after initial training in both a narrow (1÷2-octave) and a wide (3-octave) training range. The latter range encompasses a substantial portion of the entire frequency range audible to starlings. Therefore, the constraint is independent of the size of the training range. No known principles of stimulus discrimination or generalization account for the constraint. We also obtained further evidence on starlings’ sensitivity to relative pitch in auditory pattern perception. We used probe stimuli to explore pattern discrimination in narrow local regions of the wide frequency range. The probe data showed that, in spite of the frequency range constraint, the starlings were able to process pitch patterns on a relational basis. The results join earlier data indicating that both absolute and relative pitch processing may be involved in the natural auditory communication of songbirds.     

The Norwegian perspective on issues of quality in day care

Since 1953, Norwegian national standards regulate ratios of children to staff, training requirements, group sizes, leadership and subsidies. Both national and local subsidies support the management and quality level of day care centers. In Norway a current viewpoint on quality in day care is to stimulate innovation in day care activities by rewarding local initiative and creativity. Outdoor activities and giving the children freedom to learn are highly valued. Preschool teacher education, which is three years at college, shares a common frame of a governmental curricular guideline as well as a nationwide curriculum for day care. A responsive and warm interaction between staff, children and parents is a definite moral value of the preschool teacher profession. Current issues of quality are related to the shortage of highly qualified directors and leaders in public day care as well as the expansion of private centers with questionable quality. Quality control of day care centers is now discussed as a necessary surveillance system of the quality of contexts and interactions in children’s daily life.     

Interpersonal conflict: Effects of variations in manner of expressing anger and justification for anger upon perceptions of appropriateness,competence, and satisfaction

Using a 3x3 factorial design, nine scenarios were developed in which a spouse had either a strong, moderate, or weak justification for becoming angry at a subject who was instructed to assume the role of the other spouse. In each senario, the spouse confronted the subject and expressed anger in one of three ways: assertively, aggressively, or non‐assertively. Subjects responded to the spouse's expression of anger on scales measuring perceptions of appropriateness, competence, and satisfaction. Findings contradicted conventional wisdom and research findings on assertive communication. Implications of the results along with suggestions for future research were offered.     

Promoting toddlers' self-regulation and healthy eating habits among families living in poverty: A randomized controlled trial of Recipe 4 Success

The Recipe 4 Success preventive intervention targeted multiple factors critical to the health and well-being of toddlers living in poverty. This randomized controlled trial, which was embedded within Early Head Start home visits for 12 weeks, included 242 racially and ethnically diverse families (51% girls; toddler mean age = 2.58 years; data collected 2016–2019). Compared to parents in usual practice home visits, parents in Recipe 4 Success displayed greater sensitive scaffolding of toddlers' learning and more responsive food parenting practices (Cohen's d = .21–.30). Toddlers in Recipe 4 Success exhibited greater self-regulation and had healthier eating habits (Cohen's d = |.16–.35|). Results highlight the value of Recipe 4 Success in promoting parent and toddler behavior change that could have life-long benefits.
