The purpose of the present study was to determine the effects of 10-in [0.25-m] versus 16-in [0.41-m] wheelchair handrims on cardiorespiratory and psychophysiological exercise responses during wheelchair propulsion at selected velocities. Fifteen male paraplegics (27.0 +/- 5.5 yrs) performed three discontinuous exercise tests (ACE = arm crank ergometer; WERG = wheelchair roller ergometer) and two 1600-m performance-based track trials (TRACK) under simulated race conditions. There were no significant differences in HR, VO2, VE, HLa, or category-ratio ratings of perceived exertion (RPE) using different handrims during wheelchair propulsion at 4 km.h-1. In contrast, at 8 km.h-1 subjects demonstrated a 13% lower steady state VO2 (p less than .05) using the 10-in handrims, coincident with a 23% lower VE. Steady state HR during WERG at 8 km.h-1 using the 10-in (124.4 +/- 3.9 b.min-1) or 16-in (130.6 +/- 4.6 b.min-1) handrims were not significantly different. There were also no significant differences between ACE or WERG conditions during maximal effort for VO2 or VE. However, HRpeak during ACE was 7% higher than HRpeak during WERG16 (183 +/- 15 b.min-1 vs. 171 +/- 12 b.min-1, p less than .05), and whole blood HLa during ACE was also significantly higher (by 2.3-2.5 mmol; p less than .05) compared to WERG. There were no significant differences for HR, performance time, or RPE between trials using different handrim diameters during the 1600-m event.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Gamification is the use of game mechanics to drive game-like engagements and actions. It applies game mechanics, dynamics and frameworks to promote desired learning behaviours. Positive and effective gamification could enhance learning and engage learners in more social and context-rich decision-making for problem-solving in learning tasks. Effective gamification design should understand the game personalities of learners, social engagement styles, and intrinsic- and extrinsic-motivated user styles initially and evaluate and select appropriate game mechanics, game dynamics, to create ideal gamification instructions. The research question this study investigated is: How will four types of gaming personalities (i.e. Explorer, Socialiser, Killer and Achiever) predict the level of game dynamics in online discussion environments? This study concluded that examining how gaming personalities relate to game dynamics in a gamified online discussion instruction is not sufficient to design effective gamification. It suggests future studies in game instructions should focus on the relationships between game dynamics, gamification contexts, gaming personalities or preferences, dynamic gaming engagement styles, etc.  相似文献

Previous research has established that interest in a text is related to better comprehension and recall, but the impact of interest on comprehension in testing situations has not been widely investigated. This study used Hierarchical Linear Models (HLM) to examine the relationship between students' interest in reading passages and their performance on reading comprehension test items over those passages. The study involved 19,735 students in Grades 4 through 8. Stimuli consisted of 98 different reading passages. A small but significant relationship between interest and test performance was found, which was stronger for girls and for students of higher ability levels. A second HLM analysis was employed to explore whether certain passage characteristics were associated with higher or lower interest. The implications for test construction are discussed.  相似文献

The purpose of this study was to provide an opportunity for science teachers to listen to adolescent girls discuss their ideas and feelings about the contemporary structure of middle-level science education. The reflections of these teachers were then analyzed to capture how the teachers interpreted what adolescent girls had to say and the action that they will take in the classroom as a result of those interpretations. This qualitative study investigated 11 teachers and 51 Grade 7 and 8 girls from various states across the continental USA. The girls discussed such things as their favorite science topics, comfort level in science classrooms, and curiosities about the physical world. The study revealed that adolescent girls strive to make a connection to science. They can see how science can help them to understand better themselves and their world, but they seldom find such understandings in contemporary science classrooms. In addition, adolescent girls not only need to have choices in their studies, but they understand that need. The study revealed that the teachers interpreted the girls' request from an assimilative perspective by seeking ways to help the girls fit into the existing structure of science education. The implications of the study suggest that science education will need to change in response to the voices of the others, but that change will only happen if we prepare teachers better to be prepared to listen and change practice in light of what they hear.  相似文献

In this study we examined response patterns in exchanges between males and females and their effects on gender participation in five online debates. Students classified messages into arguments, evidence, critiques, and elaborations while posting messages to the debates to facilitate argumentation and the sequential analysis of message-response sequences. The findings revealed no differences in number of critiques posted in response to arguments because females were just as likely as males to critique messages from both males and females, and because females responded to males with critiques at a higher than expected frequency. Posthoc analysis revealed strong indications that females posted fewer rebuttals to the critiques of females than males, and males posted more rebuttals to the critiques of females than females. The methods used in this study illustrate a process-oriented approach to explain and predict gender differences in participation and serve as a framework for future research on gender participation, group interaction, and strategies for facilitating collaborative argumentation and problem solving.  相似文献

As university professors we sought to disrupt the practice of giving our students the actions we felt they should imitate in their teaching practice. Instead, we sought to actively engage teachers in the creation of workable solutions to real-life problems. We accomplished this by conducting a participatory action research project. This paper illustrates our action research project focused on preparing middle level science teachers to foster inquiry-based learning in their classrooms. The findings of this study not only lead to a revised professional development opportunity for science teachers, but also provided an example of university faculty engaging in pragmatic research focused on addressing contemporary issues in K-12 science education. The work reported within was partially supported by a National Science Foundation Grant. The opinions, views and conclusions expressed in this paper may not reflect those of the funding agency.  相似文献
