初二学生解几何应用题策略类型的研究 总被引:1,自引:0,他引:1
运用作品分析法对60份初二优秀生、中等生、差生的第一学期数学期中考试卷进行分析,发现初二不同学习水平学生解数学应用题时表现出不同的解题策略类型:优秀生的解题策略属于“俯瞰型”;中等生的解题策略属于“经验型”;差生的解题策略属于“盲试型”。 相似文献

Online testing of infants by recording video with a webcam has the potential to improve the replicability of developmental studies by facilitating larger sample sizes and by allowing methods (including recruitment) to be specified in code. However, the recorded video still needs to be manually scored. This labour-intensive process puts downward pressure on sample sizes and requires subjective judgements that may not be reproducible in a different laboratory. Here we present the first fully automatic pipeline, using a face analysis software-as-a-service and a discriminant-analysis classifier to score infant videos acquired online. We compare human and machine performance for looking time and preferential looking paradigms; machine performance demonstrates a promising proof of principle for looking time and is above chance in classifying preferential looking. Additionally, we studied the characteristics of the video and the child that influenced automated scoring, so that future studies can acquire data that maximises the performance of automatic gaze coding and/or focus on improving automatic coding for particularly challenging data. We believe this technology has great promise for developmental science. 相似文献

本文在11只上海家免上进行了色觉行为学的实验研究。通过限制方位、光强等可能成为条件刺激的因素,并排除了声音、气味、背景光刺激等的干扰,确保颜色成为唯一的条件刺激,建立食物性红绿色觉分辨条件反射。经过适应、筛选、驯练和测试,在家兔上建立了对绿光稳固的条件反射。该结果显示兔具有颜色分辨能力。 相似文献

先天性色觉异常的特性及检查方法 总被引:2,自引:0,他引:2
本文简单介绍了各种先天性色觉异常的特性及常用的色觉检查方法。不同类型的先天性色觉异常在颜色匹配、光谱感受性、色差辨别等方面均表现出不同的特点,色觉检查方法就是在这些特点的基础上,根据异常者的某一色觉缺陷设计的。常用的检查方法有假同色图测验,色相排列测验和色盲镜等。一般来说,不同的检查方法各有所长,并应用于临床的不同阶段 相似文献

Three adult female elephants (Elephas maximus) were tested on a light-dark discrimination problem with an 8-yr intertrial interval. The first subject took only 6 min to reach criterion and made only two errors, suggesting remarkable retention. The other two subjects were found to have visual anomalies that would have gone undetected without this research. 相似文献

Aim: This paper seeks to understand whether Maltese school counsellors are equipped to deal with dyslexic clients, considers whether specific strategies need to be used, and what positive effects, if any, counselling has on these clients. Previous studies: A literature review on self-concept and techniques on how to improve the self-concept of children with Learning Disabilities (LD)/Specific Learning Difficulties (SpLD) will place the current study in context. Method: Questionnaires (available from the authors on request) were distributed to all school counsellors on the island and analysed using content analysis. Findings: Findings from respondents indicate a need for more training, evidence-based knowledge of specific techniques when dealing effectively and successfully with dyslexic clients, specific specialised training to understand dyslexic clients and that counselling has a positive effect on dyslexic clients. 相似文献

The authors asked how sport expertise modulates visual field dependence and sensory reweighting for controlling posture. Experienced soccer athletes, ballet dancers, and nonathletes performed (a) a Rod and Frame test and (b) a 100-s bipedal stance task during which vision and proprioception were successively or concurrently disrupted in 20-s blocks. Postural adaptation was assessed in the mean center of pressure displacement, root mean square of center of pressure velocity and ankle muscles integrated electromyography activity. Soccer athletes were more field dependent than were nonathletes. During standing, dancers were more destabilized by vibration and required more time to reweigh sensory information compared with the other 2 groups. These findings reveal a sport skill–specific bias in the reweighing of sensory inputs for spatial orientation and postural control. 相似文献

This qualitative study describes the positive characteristics of an extended‐stay hotel as identified by low‐income families that resided there. Interviews were conducted with ten hotel residents using a semi‐structured interview guide and participant photographs to elicit a deeper understanding of experiencing home at a hotel. Framed in the theoretical perspective of environmental affordances, findings suggest that despite discomforts of the hotel environment, residents were still able to enjoy family independence, social engagement, a sense of safety and connection to a community context. The findings of this study may help practitioners gain a balanced perspective of non‐ideal housing conditions for planning interventions. Even in these conditions, positive characteristics can be identified to reinforce family functioning and well‐being. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献
