The Tactical Games Model (TGM) is an instructional model in which the primary assumption is to facilitate students' tactical understanding of games (i.e., response-selection and execution processes). Additionally, there is speculation that tactical understanding of one game transfers to other tactically similar games (Mitchell, Oslin & Griffin, 2006, p. 20). Limited research has been conducted regarding student response selection processes, problem representations, knowledge base development, or transfer of learning in this model. Griffin and Patton (2005) called for examination of TGM through an information processing lens. Examining action, condition, and goal responses of novice physical education students could provide significant insight to students' improved game performance. Also, examining students' engagement in particular tactical problems across diverse activities in a single game category could provide insight into how and which knowledge structures transfer. The purpose of this study was to examine fifth-grade students' tactical understanding and decision-making in a net/wall unit. A second purpose was to analyze the transfer of knowledge structures across the unit. Participants included an elementary school physical educator and purposively selected students (n=16; M=8, F=8) from a fifth-grade physical education class (N=50) at a suburban elementary school in the northeastern United States. Appropriate permission was obtained from the university's Institutional Review Board. The unit consisted of 20 lessons (50 minute classes). Select students remained in a cohort, participating with and against each other throughout the unit. Data was collected using multiple sources: (a) game performance (pre-post-unit), (b) situational knowledge quiz (pre-post-unit), (c) formal, semi-structured teacher interviews/written response to structured questions (pre-post-unit), (d) descriptive field notes, (e) video-taped and audio-taped teacher/student performances, (f) student think-aloud reports during the second game of each lesson (McPherson & Thomas, 1989), and (g) student focus group interviews (post-unit). Interviews were transcribed, open, axial, and selectively coded, then triangulated to develop categories. Situational quizzes, verbal recall data, and focus group interviews were micro-analyzed using a protocol analysis developed by McPherson and Thomas (1989) to examine action, condition, and goal orientations of students. Video taped game performances were analyzed using the Game Performance Assessment Instrument (Griffin, Mitchell, & Oslin, 1997). Results contribute to the empirical support for TGM, as well as contribute to what is known about knowledge structure development and transfer of learning for 5th grade novice games players.

Jusqu'à récemment, les patients souffrant d'épilepsie réfractaire aux traitements médicamenteux étaient destinés à un avenir incertain. Le recours à la chirurgie comme traitement alternatif offre l'espoir de mener un jour une vie normale. Pour déterminer si un patient peut bénéficier d’une intervention chirurgicale, une évaluation complète est cruciale. Les méthodes d’évaluation préchirurgicale ont connu des progrès importants au cours des dernières décennies avec le perfectionnement des techniques d’imagerie cérébrale. Parmi ces techniques, la spectroscopie proche infrarouge (SPIR), aussi connue sous le nom d’imagerie optique, présente de nombreux avantages (coût, mobilité du participant, résolution spatiale et temporelle, etc.). L’objectif principal de cette étude est de développer un protocole d'évaluation préchirurgicale de la mémoire. Une tâche de mémoire verbale incluant l’encodage, le rappel immédiat et le rappel différé de listes de mots a été administrée à dix adultes sains lors d’un enregistrement en imagerie optique. Les résultats obtenus suggèrent l’activation bilatérale des aires préfrontales antérieures et dorsolatérales ainsi que des aires temporales antérieures et moyennes. Les aires préfrontales et temporales antérieures semblent modulées par les différents processus mnésiques et la position du rappel dans le temps. La première fois qu’une liste est rappelée, l’activité hémodynamique est plus élevée que lors des rappels subséquents, et ce, davantage dans l’hémisphère gauche que dans l’hémisphère droit. Cette étude constitue la première étape dans le processus de validation du protocole à des fins cliniques auprès de patients épileptiques. / Until recently, patients with epilepsy refractory to drug treatments were intended to an uncertain future. Surgery as an alternative treatment offers hope to, one day, lead a normal life. In order to determine if a patient may benefit from a surgical intervention, a complete evaluation is essential. With the advancements in brain imagery techniques over the last few decades, preoperative evaluation methods have seen important progress. Among these techniques, near infrared spectroscopy (NIRS), also known as optical imaging, presents numerous advantages (cost, participant mobility, spatial and temporal resolution, etc.). The purpose of this study is to develop a preoperative evaluation protocol for memory assessment. During a NIRS recording, a verbal memory task including encoding, immediate and delayed free-recall of a list of words was administered to ten healthy adults. The results obtained revealed bilateral activation of anterior and dorsolateral prefrontal areas as well as anterior and median temporal areas. Prefrontal and anterior temporal areas seemed to be regulated by different memory processes and the recall location in time. The first time that a list is recalled, increased hemodynamic activity is observed in comparison to subsequent recalls, with a greater activity in the left hemisphere than in the right hemisphere. This study constitutes the first step in the validation process of the protocol for clinical needs among epileptic patients.
