The Role of Statistical Learning in Word Reading and Spelling Development: More Questions Than Answers     

Amy M. Elleman  Laura M. Steacy 《Scientific Studies of Reading》2019,23(1):1-7

ABSTRACT

This special issue bundles a set of eight empirical studies and one review article that explore the role of statistical learning (SL) mechanisms (both domain-specific and domain-general) in supporting word reading and spelling development, and vice versa. In this introduction to the special issue, we worked to summarize the extent to which studies support our hypotheses relating SL to reading and spelling development while pointing out inconsistencies across studies that require us to refine and rethink our hypotheses.  相似文献   

“‘I Was Gonna Go Off,but My Best Friend is White.”: Hispanic Students’ Co-Cultural Reasoning in a Hispanic Serving Institution     

Amy Aldridge Sanford  C. Kyle Rudick  Keith Nainby  Kathryn B. Golsan  Stephanie Rollie Rodriguez  Christopher J. Claus 《Communication quarterly》2019,67(2):158-177

The researchers engaged in a qualitative analysis (using journaling and focus group methodology) of the communicative behaviors of Hispanic students with White institutional members at a medium-sized, Southwest HSI. Utilizing Co-Cultural Theory and Elaborative Coding analysis, the authors mapped how Hispanic students narrated their co-cultural communication and reasoning (i.e., why they engage in one strategy rather than another). The findings show that, although Hispanic students used almost all co-cultural strategies, their responses were clustered primarily around assimilationist strategies – indicating that they engage in a high degree of self-monitoring and self-censorship when interacting with White institutional members in an HSI. These results suggest that even when Hispanic students constitute a large or majority part of the institution’s population, they still feel the need to engage in behaviors that navigate White norms. The study concludes by examining the findings for co-cultural theorizing as well as providing insights for instructors who wish to engage in inclusive teaching practices.  相似文献   

High school biology: What makes it a challenge for teachers?     

Amy A. Strage  Linda Bol 《科学教学研究杂志》1996,33(7):753-772

This study contributes to our understanding of the complex issues inherent in dealing with the heterogeneity of current high school science classrooms, by reporting on in-depth interviews with 38 experienced biology teachers. Analyses of teachers' responses revealed complex and occasionally counter-intuitive relationships among: (a) their perceptions of what was distinctive about their school, its biology program, or their students; (b) their allocation of class time; (c) their efforts to individualize instruction and meet the needs of a heterogeneous student population; (d) their student outcome goals; and (e) the methods they used to evaluate student progress. Thus, for example, of the 9 teachers who cited the diversity of their students. 4 also commented on their poor motivation, but another 4 also commented on their high motivation. In addition, teachers reported using a similar range of instructional formats but for different reasons, depending on the characteristics of their students (e.g., cooperative learning groups used to compensate for poor attention spans, to challenge bright students, and to foster social tolerance). Discussion of these findings addresses several points of relevance for science education, teacher preparation, and curriculum reform. © 1996 John Wiley & Sons, Inc.  相似文献   

Virtual-reality exergaming improves performance during high-intensity interval training     

Matthew Farrow  Christof Lutteroth  Peter C. Rouse 《European Journal of Sport Science》2019,19(6):719-727

Purpose: To determine if: (i) mean power output and enjoyment of high-intensity interval training (HIIT) are enhanced by virtual-reality (VR)-exergaming (track mode) compared to standard ergometry (blank mode), (ii) if mean power output of HIIT can be increased by allowing participants to race against their own performance (ghost mode) or by increasing the resistance (hard mode), without compromising exercise enjoyment.

Methods: Sixteen participants (8 males, 8 females, VO₂max: 41.2?±?10.8 ml^?1·kg^?1·min^?1) completed four VR-HIIT conditions in a partially-randomised cross-over study; (1a) blank, (1b) track, (2a) ghost, and (2b) hard. VR-HIIT sessions consisted of eight 60 s high-intensity intervals at a resistance equivalent to 70% (77% for hard) maximum power output (P_MAX), interspersed by 60 s recovery intervals at 12.5% P_MAX, at a self-selected cadence. Expired gases were collected and VO₂ measured continuously. Post-exercise questionnaires were administered to identify differences in indices related to intrinsic motivation, subjective vitality, and future exercise intentions.

Results: Enjoyment was higher for track vs. blank (difference: 0.9; 95% CI: 0.6, 1.3) with no other differences between conditions. There was no difference in mean power output for track vs. blank, however it was higher for track vs. ghost (difference: 5 Watts; CI: 3, 7), and hard vs. ghost (difference: 19 Watts; 95% CI: 15, 23).

Conclusions: These findings demonstrate that VR-exergaming is an effective intervention to increase enjoyment during a single bout of HIIT in untrained individuals. The presence of a ghost may be an effective method to increase exercise intensity of VR-HIIT.  相似文献

Kinematic analysis of hip and knee rotation and other contributors to ballet turnout     

Amy E. Quanbeck  Sara C. Handley  Deborah S. Quanbeck 《Journal of sports sciences》2017,35(4):331-338

Turnout, or external rotation (ER) of the lower extremities, is essential in ballet. The purpose of this study was to utilise physical examination and a biomechanical method for obtaining functional kinematic data using hip and knee joint centres to identify the relative turnout contributions from hip rotation, femoral anteversion, knee rotation, tibial torsion, and other sources. Ten female dancers received a lower extremity alignment assessment, including passive hip rotation, femoral anteversion, tibial torsion, weightbearing foot alignment, and Beighton hypermobility score. Next, turnout was assessed using plantar pressure plots and three-dimensional motion analysis; participants performed turnout to ballet first position on both a plantar pressure mat and friction-reducing discs. A retro-reflective functional marker motion capture system mapped the lower extremities and hip and knee joint centres. Mean total turnout was 129±15.7° via plantar pressure plots and 135±17.8° via kinematics. Bilateral hip ER during turnout was 49±10.2° (36% of total turnout). Bilateral knee ER during turnout was 41±5.9° (32% of total turnout). Hip ER contribution to total turnout measured kinematically was less than expected compared to other studies, where hip ER was determined without functional kinematic data. Knee ER contributed substantially more turnout than expected or previously reported. This analysis method allows precise assessment of turnout contributors.  相似文献   

New media environments’ comparative effects upon intercultural sensitivity: A five-dimensional analysis     

Amy Jo Coffey  Rasha Kamhawi  Paul Fishwick  Julie Henderson 《Int J Intercult Relat》2013

An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life^®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness.  相似文献   

ROUSSEAU'S IMAGINARY FRIEND: CHILDHOOD,PLAY, AND SUSPICION OF THE IMAGINATION IN EMILE     

Amy B. Shuffelton 《Educational theory》2012,62(3):305-321

In this essay Amy Shuffelton considers Jean‐Jacques Rousseau's suspicion of imagination, which is, paradoxically, offered in the context of an imaginative construction of a child's upbringing. First, Shuffelton articulates Rousseau's reasons for opposing children's development of imagination and their engagement in the sort of imaginative play that is nowadays considered a hallmark of early and middle childhood. Second, she weighs the merits of Rousseau's opposition, which runs against the consensus of contemporary social science research on childhood imaginative play. Ultimately, Shuffelton argues that Rousseau's work offers an important cautionary note to enthusiasts of children's imaginative play, due to the potentially disruptive influence of consumer capitalism, though she also notes that imagination may play a more redemptive role than Rousseau granted it.  相似文献
