The purpose of the experiments was to determine the automatic use of large or small word reading units in young readers in the absence of word decoding strategies. Picture-word Stroop interference was examined from four types of conflicting labels: (a) words containing both highly predictable grapheme–phoneme correspondence (GPC) units and highly consistent rime units (henceforth, Hi-GPC + Hi-Rime); (b) words with highly predictable GPC units and less consistent rime units (Hi-GPC + Lo-Rime); (c) words with low predictability GPC units and highly consistent rime units (Low GPC + High Rime); (d) nonwords that contained both highly predictable GPC and highly consistent rime units. Naming time for pictures containing these labels was compared against that for pictures with random letter strings or no labels. In Experiment 1, Stroop interference was examined in first, second, and third grade children to determine whether there was developmental change in the presence of rime or GPC interference. In Experiment 2, Stroop interference was examined as a function of relative reading skill in first grade children. In Experiment 3, Stroop interference in adults was compared to the use of rime or GPC pronunciation strategies for nonword reading. In all experiments, Stroop interference in picture naming was longer for pictures with highly predictable GPC unit labels than less predictable GPC unit labels. However, in Experiment 3, even though adults showed interference from predictable GPC units in the Stroop task, they always preferred rime pronunciation for ambiguous nonwords in the nonword reading task. It is argued that the current experiments provide evidence for a flexible units model. The results of this study were presented at the Cognitive Development Society meeting, November 2001, Virginia Beach, VA, and the American Educational Research Association meeting, April 2004, San Diego, California.  相似文献   

小学儿童心理理论发展特点研究     

高秀苹 《山东教育学院学报》2008,23(2):7-10

文章主要探讨了小学阶段儿童心理理论发展的特点。采用失言和白谎两种心理理论任务对小学2、4、6年级90名儿童进行测量,考察心理理论水平的年级差异和性别差异。结果发现（1）小学儿童心理理论能力总体上有明显发展,但儿童对失言和白谎的理解在不同阶段呈现出不同的发展特点;（2）小学阶段儿童的心理理论能力存在显著的性别差异,女孩的心理理论成绩显著地好于男孩。男孩和女孩在心理理论发展速度上存在一定差异。  相似文献   

Measuring children’s perceived cost of school science: Instrument development and psychometric evaluation     

《Studies in Educational Evaluation》2021

This investigation addresses the need for valid and reliable instruments that contribute to understanding the factors that lead to the rejection of science-related studies. We discuss the theoretical and methodological limitations of published attitudes toward science questionnaires and describe the development and validation of a short instrument rooted in the cost construct of the expectancy-value model of achievement motivation. We collected data from a sample of six hundred thirty-two 5^th and 6^th (M_age = 10.87; SD = .76) elementary students in Spain. Exploratory and confirmatory factor analysis revealed a parsimonious structure measuring loss of valued alternatives and task effort ​cost. Further psychometric evaluation displayed evidence for convergent, discriminant, and concurrent validity. Likewise, the reliability was acceptable for both three-item scales. These findings support the proposed instrument to measure barriers experienced by Spanish children when studying school science.  相似文献

TBL教学理念中的情境设计   总被引：1，自引：0，他引：1  

袁菲 《中国教育研究与创新》2006,3(6):8-9

任务型教学（task-based learning，简称TBL）作为一种新的教学理念强调以学生为主体，要求学习者通过完成任务，用目标语进行有目的的交际活动。任务型教学理论的目的在于用“任务”来引导学习。在这里，我们认为，任务仅仅是学习的手段，而“情”才是触发学生学习的动力，所以任务设计最根本的是要体现情境设计中的“情”字。  相似文献   

Unpacking task-technology fit to explore the business value of big data analytics     

《International Journal of Information Management》2023

Understanding how the application of big data analytics (BDA) generates business value is a persistent challenge in information systems (IS) research. Improving understanding of how BDA realizes business value requires unpacking theories to study the phenomenon. This study unpacks the task-technology fit (TTF) theory toward generating new and improved insights into the business value of BDA. Extant studies on TTF have mainly focused on traditional IT which is different from digital technologies like BDA that are malleable and dynamic. While TTF has primarily focused on how the technology meets task requirements, this study contends that tasks can also be structured to fit the functionality of technology. This study proposes a 2 × 2 matrix framework to explain how BDA and tasks interact. The framework indicates how the reconfigurability of tasks and the editability of BDA impact the fit between tasks and BDA. Future research should explore how the fit between tasks and BDA changes over time.  相似文献
