Many rural indigenous communities rely on science knowledge and innovation for survival and economic advancement, which requires community members to be motivated for learning science. Children in these communities have been viewed by some as unmotivated due to their low science achievement as they progress in school, particularly into majority secondary schools. Current theories of motivation, such as achievement goal theory, take classroom context into account when examining individual motivation. However, motivational climate can also be considered as tightly woven with the cultural and social practices of a community rather than individual perception. In this study, researchers spent time in two indigenous villages observing classrooms, participating in community events, and talking with community members. During those visits, Attayal/Sediq children in Taiwan (n?=?18) and Mopan Mayan children in Belize (n?=?18) participated in three semi-structured interviews about their experience learning science in school, home, and community. Results indicate that motivation for learning science is closely linked with their identity as science learners. Three themes emerged to illuminate how social practices may or may not support individual identity, and consequently motivation, for learning science—student/teacher relationships, support for learning, and motivational climate. Differences between children in Taiwan and Belize are explored. Implications for motivation theory, educational practice, and policy are discussed.  相似文献

Abstract

This study investigated the interaction between emotion-eliciting pictures and power output during a repetitive supra-maximal task on a cycle ergometre. Twelve male participants (mean (±SD) age, height and weight: 28.58 ± 3.23 years, 1.78 ± 0.05 m and 82.41 ± 13.29 kg) performed 5 repeated sprint tests on a cycle ergometre in front of neutral, pleasant or unpleasant pictures. For each sprint, mechanical (peak power and work), physiological (heart rate) and perceptual (affective load) indices were analysed. Affective load was calculated from the ratings of perceived exertion, which reflected the amount of pleasant and unpleasant responses experienced during exercise. The results showed that peak power, work and heart rate values were significantly lower (P < 0.05) for unpleasant pictures (9.18 ± 0.20 W ? kg?1; 47.69 ± 1.08 J ? kg?1; 152 ± 4 bpm) when compared with pleasant ones (9.50 ± 0.20 W ? kg?1; 50.11 ± 0.11 J ? kg?1; 156 ± 3 bpm). Furthermore, the affective load was found to be similar for the pleasant and unpleasant sessions. All together, these results suggested that the ability to produce maximal power output depended on whether the emotional context was pleasant or unpleasant. The fact that the power output was lower in the unpleasant versus pleasant session could reflect a regulatory process aimed at maintaining a similar level of affective load for both sessions.  相似文献

This study investigated the ability of preterm infants to learn an object shape with one hand and discriminate a new shape in the opposite hand (without visual control). Twenty-four preterm infants between 33 and 34 + 6 gestational weeks received a tactile habituation task with either their right or left hand followed by a tactile discrimination task in the opposite hand. The results confirmed that habituation occurred for both shapes and both hands. Infants subsequently held the novel shape longer in the opposite hand. The results reveal that preterm infants are capable of intermanual transfer of shape information. In spite of the immaturity of the corpus callosum in preterm infants, its development seems to be sufficient to allow some transfer of information between both hands.  相似文献

This paper describes a case study presented to students in computer science during a course on formal techniques for protocol validation. The course teaches some basic notions on specification, simulation, verification, testing and distributed observation. The case study is the classical alternating-bit protocol. The exercise first consists of some simple modeling and simulation of the specification and verification of some basic service properties. It is then followed with the problem of observation of distributed executions of the protocol. This kind of experiment was found to be useful for students, since they gain an understanding of the importance and necessity of formal methods for protocol validation.  相似文献

Teacher attrition: state of knowledge – At a time when a number of countries are concerned about teacher shortages, the question arises why so many teachers are leaving the profession. This review of the literature, based on the analysis of 69 scientific papers (containing either empirical data or rigorous theoretical analysis) specifically aims to provide answers to this question by identifying the factors involved in teacher attrition. The listed factors are divided into three categories (factors related to teaching tasks, to the teacher or to the social environment), and then examined in the conclusion.  相似文献

This study investigated the effects of fatigue on balance control and cognitive performance in a standing shooting position. Nineteen soldiers were asked to stand while holding a rifle (single task – ST). They also had to perform this postural task while simultaneously completing a cognitive task (dual task – DT). Both the ST and DT were performed in pre- and post-fatigue conditions. In pre-fatigue, participants achieved better balance control in the DT than in the ST, thus suggesting that the increased cognitive activity associated with the DT improves balance control by shifting the attentional focus away from a highly automatised activity. In post-fatigue, balance control was degraded in both the ST and DT, while reaction time was enhanced in the first minutes following the fatiguing exercise without affecting the accuracy of response in the cognitive task, which highlights the relative independent effects of fatigue on balance control and cognitive performance.  相似文献

Our challenge as teachers and as human beings is to begin the process of "changing our voices," facing who we are and what that means in a society based on power and oppression. We must learn to listen to others, so we can speak together with voices both united and unique. The journey described is personal, yet it is also generalizable. Changing one's voice may be the only real way in which a teacher can be a model of diversity and multiculturalism. If as a teacher I do nothing to change my own voice, I have accomplished little in terms of effective teaching. My attitudes, behaviors, words should reflect and embody humanity, not just those who "look" like me or are thought of as more capable learners. I must challenge my students' thinking in terms of diversity and multicultural issues and push them to think of the "other."  相似文献

The aim of this study was to assess responses to taper in elite athletes using computer simulations. Parameters of a non-linear model were derived from training and performance data over two seasons for eight elite swimmers. The fit between modelled and actual performances was statistically significant for each swimmer (r(2) = 0.56 +/- 0.06; P < 0.01). The simulations were used to estimate characteristics of step and progressive tapers that would maximize performance either (1) after regular training only or (2) after overload training of a 20% step increase in regular training for 28 days. The highest performance with a step taper was greater with than without prior overload training (101.4%, s = 1.6 vs. 101.1%, s = 1.4 of personal record; P < 0.01) but required a longer taper duration (22.4 days, s = 13.4 vs. 16.4 days, s = 10.3; P < 0.05). The optimal progressive taper led to a better performance only after the overload period (101.5%, s = 1.5; P < 0.001). Negative and positive influences of training were estimated as indicators of fatigue and adaptations to training respectively. During the optimal taper, the negative influence was completely removed, independently of the prior training, whereas the positive influence increased only after overload training. Our computer simulations show that the characteristics of an optimal training reduction in elite athletes depend on the training performed in the weeks prior to a taper.  相似文献
