Adaptive educational games provide new opportunities to train early numerical skills. However, empirical evidence for the effectiveness of adaptive educational games is scarce. This study investigated the effectiveness of an adaptive game compared to a nonadaptive game in terms of cognitive, noncognitive and efficiency outcomes. In total, 84 children were randomly assigned to a condition in which children trained early numerical skills with an adaptive version of the Number Sense Game (NSG), or to a condition in which they trained with a nonadaptive version. Early numeracy was evaluated before the training, immediately after the training and 3 weeks after the training. Math anxiety (MA) was assessed before and 3 weeks after the training. The time children practiced with the NSG was used to assess efficiency. Results revealed that children in both conditions improved on early numerical ability, with sustained effects 3 weeks after the training. In both conditions, children’s MA scores were lower after the training. Children in the adaptive condition learned more efficiently compared to the nonadaptive condition, and the interaction between prior knowledge and condition has shown that children with low prior knowledge benefited more from a nonadaptive training while children with high prior knowledge benefited more from an adaptive training in terms of learning efficiency. These results confirm that adaptive educational games can offer solace in terms of the need for differentiation. 相似文献

Although previous research has shown the potential of innovative learning for enhancing motivation and learning outcomes, further understanding is needed on which aspects of IL are most effective and whether these are equally motivating for different types of students. The present study investigated how developments in students’ motivation and achievement related to different aspects of innovative learning (i.e. authentic learning, collaborative learning and focusing on self-regulation), and whether these relations varied by students’ background characteristics. A sample of 722 grade five students from the Netherlands (average age 11?years old) and their teachers completed questionnaires during four measurements from grade five to grade six. Autoregression analyses were performed. Results showed both positive and negative relations between IL and developments in students’ motivation and achievement, indicating that IL is not a unidimensional construct. Furthermore, the effectiveness of different aspects of IL depended on students’ gender, and social and ethnic background characteristics. 相似文献

This article concerns the relationship between social–educational goals and the school context. We used a questionnaire to map the educational goals of teachers in pre-vocational education in the field of social competence, and investigated whether these goals were related to the percentage of students from ethnic-minority groups and to the urban environment of the school. The results show that all teachers, regardless of the school context, value promoting the social development of their students as an educational goal. We did not find a relationship between the context the teachers work in and the social-competence goals they aspire to in their subject. However, teachers working in a more complex school environment, in terms of both the ethnic heterogeneity of the student population and the urban environment of the school, did consider a number of social-competence goals to be less attainable for their students. The results are discussed in the light of research on the competences young people need to participate in a multi-cultural society and the implications for teachers and teaching. 相似文献

Internal laws of probability, generalized likelihoods and Lewis' infinitesimal chances-A response to Adam Elga 总被引：1，自引：0，他引：1
The rejection of an infinitesimal solution to the zero-fit problemby A. Elga ([2004]) does not seem to appreciate the opportunitiesprovided by the use of internal finitely-additive probabilitymeasures. Indeed, internal laws of probability can be used tofind a satisfactory infinitesimal answer to many zero-fit problems,not only to the one suggested by Elga, but also to the Markovchain (that is, discrete and memory-less) models of reality.Moreover, the generalization of likelihoods that Elga has inmind is not as hopeless as it appears to be in his article.In fact, for many practically important examples, through theuse of likelihoods one can succeed in circumventing the zero-fitproblem.

Purpose: There is currently no standardized testing protocol for assessing clients’ fitness/health within the Australian fitness industry. This study examined the perceptions of the feasibility of using a standardized testing protocol among Australian fitness industry professionals. Method: In 2014, 1,206 registered fitness industry professionals (aged 17–69 years) completed an online survey. Perceived feasibility for using a standardized testing protocol was assessed based on responses to 6 items. Respondents were classified as having a high level of perceived feasibility if they reported all 6 items to be “definitely feasible.” A multivariate logistic regression analysis, adjusting for demographic and fitness industry-related factors (e.g., qualification/years of experience), assessed the likelihood of having a high level of perceived feasibility. Results: Overall, 25.5% (95% CI [23.1%, 28.0%]) of the sample perceived the use of a standardized testing protocol as highly feasible. Items ranked most often as “definitely feasible” were “undertaking training to use the protocol” (55%) and “conducting follow-up testing every 6 to 12 weeks” (52%). After adjustment for the effect of confounding factors, casually employed professionals (OR = 0.63; 95% CI [0.45, 0.90]) and group instructors (OR = 0.58; 95% CI [0.41, 0.82]) were less likely to perceive standardized testing protocols as highly feasible. Conclusions: Among a large sample of Australian fitness industry professionals, slightly more than a quarter perceived using a standardized testing protocol to be highly feasible. Group instructors and casual employees perceived lower feasibility. Further research should determine the barriers to implementing a standardized testing protocol across the fitness industry. 相似文献

Abstract The aim of this study was to examine the effect of movement and stretching imagery on increases in flexibility. Thirty volunteers took part in a 4 week flexibility training programme. They were randomly assigned to one of three groups: (1) movement imagery, where participants imagined moving the limb they were stretching; (2) stretching imagery, where participants imagined the physiological processes involved in stretching the muscle; and (3) control, where participants did not engage in mental imagery. Active and passive range of motion around the hip was assessed before and after the programme. Participants provided specific ratings of vividness and comfort throughout the programme. Results showed significant increases in flexibility over time, but no differences between the three groups. A significant relationship was found, however, between improved flexibility and vividness ratings in the movement imagery group. Furthermore, both imagery groups scored significantly higher than the control group on levels of comfort, with the movement imagery group also scoring significantly higher than the stretching imagery group. We conclude that the imagery had stronger psychological than physiological effects, but that there is potential for enhancing physiological effects by maximizing imagery vividness, particularly for movement imagery. 相似文献

An effective start enhances an athlete's chances of success in ski cross competitions. Accordingly, this study was designed to investigate the biomechanics of start techniques used by elite athletes and assess the influence of different start environments. Seven elite ski cross athletes performed starts indoors on a custom-built ramp; six of these also performed starts on an outdoor slope. Horizontal and vertical forces were measured by force transducers located in the handles of the start gate and a 12-camera motion capture system allowed monitoring of the sagittal knee, hip, shoulder, and elbow kinematics. The starting movement involved Pre, Pull, and Push phases. Significant differences between body sides were observed for peak vertical and resultant forces, resultant impulse, and peak angular velocity of the shoulder joint. Significantly lower peak vertical forces (44 N), higher resultant impulse (0.114 Ns/kg), and knee joint range of motion (12°) were observed indoors. Although movement in the ski cross start is generally symmetrical, asymmetric patterns of force were observed among the athletes. Two different movement strategies, i.e. pronounced hip extension or more accentuated elbow flexion, were utilised in the Pull phase. The patterns of force and movement during the indoor and outdoor starts were similar. 相似文献

Research on Self-Determination Theory has shown that teachers’ need-supportive behaviour is associated with student motivation and engagement. The purpose of this study is to examine the effectiveness of an intervention aimed at increasing the motivation of students with congenital and acquired deafblindness by enhancing teachers’ need-supportive behaviour. To assess the intervention effect, this study follows a multiple case-study design. Teacher questionnaires were administered and video observations of teacher–student interactions were made during pre-test, post-test and follow-up phases. The results showed that teachers provided involvement most, followed by structure and autonomy support. Teachers’ provision of structure and autonomy seems to improve most after the intervention. In general, teachers of students with congenital deafblindness showed larger intervention effects than teachers of students with acquired deafblindness. The results also provide indications that students’ levels of engagement improved after the intervention. 相似文献
