Cooperative learning: a relevant instructional model for physical education pre-service teacher training?

Background: One of the key questions of physical education teacher educators (PETE) programmes refers to whether future teachers are prepared to build knowledge and skills to feel self-efficacious in teaching physical education (PE). This issue concerns the instructional model of teaching used to help PE pre-service teachers to master both pedagogical knowledge and motor skills. According to this twofold challenge, the direct instruction (DI) is mainly used for pre-service teacher training. Beyond this traditional model, other instructional models as cooperative learning (CL) approach arise in the initial PE teacher education. Nevertheless, surrounding attempts at innovation, little information related to the instructor’s role. Under the social cognitive perspective of self-efficacy and instructional competency building, more information is currently expected with regard to the strategies the instructor uses to scaffold the mastery of skills for PE pre-service teachers’ effective teaching.

Purpose: The purpose of this article is to consider whether PE pre-service teachers are trained during short training sessions aimed to discover new physical activities. We examine the influence of a scaffolding procedure (CLS design) on PE pre-service teachers’ knowledge, skills and self-efficacy in comparison to a CL and a DI experience. This leads to consider to what extent this instructional support provided by the instructor would help pre-service teachers to perceive themselves as self-efficacious to teach contents in PE.

Participants and design: After a pre-test, sixty-nine PE pre-service teachers were randomly assigned to one of the three following conditions: CL (14 males and 7 females); CLS (20 males and 8 females) or direct instruction condition (DI; 12 males and 8 females). For the training session a selected CL procedure (Jigsaw) [Aronson, Elliot, and Shelley Patnoe. 1997. The Jigsaw Classroom: Building Cooperation in the Classroom. 2nd ed. Wokingham: Addison-Wesley Educational]) was used to split CL and CLS participants into mixed-sex teams, whereas DI participants practiced the same exercises in dyads. According to the training conditions, the same instructor provided different information to participants along the three 2-hour instructional sessions with regard to: (a) warm-up (DI), (b) CL organization (CL), and (c) scaffolding integrated into a CL implementation (CLS).

Data collection: A Pre-test/post-test design was used to consider PE pre-service teacher’s motor skill, knowledge for practice, and self-efficacy improvements. The post-test also examined participants’ pedagogical knowledge.

Findings: The results showed that the participants in the three conditions progressed on performance, knowledge for practice, knowledge for teaching, and self-efficacy. Although no difference was found in self-efficacy between the three training conditions over time, significant differences appeared on pedagogical knowledge or/and motor skills with an advantage for the CL and CLS participants, respectively.

Conclusion: Although short training sessions dedicated to discovering new sports stay problematic for teacher professional development, implementing CL pre-service teacher training designs would be a relevant alternative. Instructional knowledge would be developed mainly when they have explicitly access to information concerning the teacher intervention. Nevertheless, such a scaffolding procedure integrated into CL training designs would need to be applied repeatedly to various physical activities to have an impact on pre-service teachers’ self-efficacy.     

Ethyl Silicate for Unbaked Earth Tablets Conservation: Evaluation of the Physico-mechanical Aspects

ABSTRACT

Preservation of cuneiform tablets made with clay minerals is an ongoing conservation issue. A treatment based on TEOS consolidation has been used since 1996 at the Louvre museum. The characterization of the tablets pointed out kaolinite, illite, and smectite as the three main clay minerals constituting the objects. In this research, the physico-mechanical aspects of the treatment are investigated. The penetration depth of the TEOS solution and the gradient induced are quantified using laboratory samples. TEOS treatment preserves the macroscopic swelling and the vapour transfer properties, but modifies the clay’s affinity to moisture. Elastic properties are gradually improved for all clays, but only kaolinite’s strength increases significantly. The impact of TEOS treatment on the natural behaviour related to the respective structure of the clays is considered, and the amount of kaolinite required to create adequate reactions appears to be of interest for conservation treatments.     

A Developmental Study of the Self-Prioritization Effect in Children Between 6 and 10 Years of Age

Self-biases are well described in adults but remain poorly understood in children. Here, we investigated in 6–10 year-old children (N = 132) the self-prioritization effect (SPE), a self-bias which reflects, in adults, the perceptual advantage for stimuli arbitrarily associated with the self as compared to those associated with other persons. We designed a child-friendly adaptation of a paradigm originally introduced in adults by Sui, He, and Humphreys (2012) in order to test whether the SPE also occurs in children and if so, to determine its evolution with age. A robust SPE was obtained from the age of 6, and this effect was similar-sized in our four age groups. These findings are discussed with reference to the development of the self during childhood.     

Visually and acoustically augmented performance feedback as an aid in motor control learning: a study of selected components of the rowing action

The present work compares the efficiency of two training techniques as aids to learning selected aspects of a sequentially ordered action such as that of rowing. Subjects in one group were trained with a conventional learning technique (CLT) while those in a second group were trained by an augmented feedback technique referred to as external feedback (EFB). Progress was recorded on learning curves. Rowing athletes with limited experience and psychophysiology students were used for the study. The tasks consisted of learning movement timing (rhythmicity of action and coordination of body parts) and movement intensity (force and electromyogram development), in four separate experiments. The learning curves for EFB subjects were found to have significantly and consistently higher slopes than those for CLT subjects. Optimal criteria were reached by EBF subjects, after a continuous increase in performance levels and a concomitant decrease in standard deviations evaluated from periodicity, movement accuracy and force. Subjects, who after 8 to 10 sessions of CLT learning had not reached optimal level, were exposed to EFB. Their performances then showed a marked improvement and attained the required criterion in 2 to 4 sessions. This further demonstrates the efficacy of EFB as compared with CLT, as an aid to learning a complex sensorimotor action. The efficacy of EFB as a learning technique is discussed in relation to the internal model of the task to be executed and to sensory motor control and motor programmes.     

Le Logiciel ‘Derive’ comme revelateur de phenomenes didactiques lies a l'utilisation d'environnements informatiques pour l'apprentissage

In this article, we address the issue of integration of computer environments in the mathematics secondary curriculum, by referring to the results of a research project carried out with the software DERIVE. Firstly, we present the research project and its theoretical framework, secondly, we evidence some didactical phenomenas linked to the DERIVE transposition of mathematical knowledge and learning processes in this environment which, in our opinion, play a crucial role in integration issues.This revised version was published online in September 2005 with corrections to the Cover Date.     

Not notable enough: feminism and expertise in Wikipedia

Wikipedia promotes itself as a community that anyone can join as long as they know the rules. In this paper, we reflect on our attempt to join this community and to edit Wikientries on ageing so that they include an intersectional perspective, especially with regard to gender. Our excursion into Wikipedia reveals how certain entries act as sites of contestation between different communities of practice, such as feminist scholars and Wikipedia experts. We document and discuss three interconnected discursive guidelines over which contestation takes place: notability, verifiability, and tone. These guidelines govern the way that Wikipedia operates in relationship to dominant discourses on age and gender. They are at the heart of its inequitable treatment of content matter.     

The breadth of peer relationships among preschoolers: an application of the Q-connectivity method to externalizing behavior

Preschoolers' (M(age) = 48.7 months) social breadth (the number of peer children interact with and the frequency of these interactions) and the relations between breadth and externalizing behaviors were examined using the Q-connectivity method. After considering age, sex, and classroom effects on social breadth, children's externalizing behaviors were studied in relation to levels of social breadth across variations in frequency of exposure to peers and to patterns of decline in social breadth. Externalizing preschoolers occasionally interacted with most of their classmates. However, their individual peer networks moderately to rapidly became selective, and they engaged in repeated interactions with a relatively small number of peers. Although there were no sex effects, significant age and classroom effects were obtained.
