The discovery of the acceleration phenomenon and the contribution of reading rate as an independent variable to the quality of the reading process brought about a systematic research project that examined the underlying factors of word reading rate. Word reading requires processing information in the visual and auditory modalities and relies on word recognition skills such as phonological and orthographic decoding. Therefore, it is believed that speed of processing of some subset of the above sub-processes affects word-reading rate. By using experimental manipulations relying on both electrophysiological (ERPs) and behavioral measures, the sub-processes that are activated in word reading can be distinguished and shown to differentiate between the early perceptual, the central cognitive, and the motoric stages of activation. Results indicate that word reading rate is related to basic speed of processing in the modalities activated during the reading process. However, the processing level within each modality that contributes to self-paced and fast word reading rate differs according to age and the efficiency of reading skills. 相似文献
Argumentation has been emphasized in recent US science education reform efforts (NGSS Lead States 2013; NRC 2012), and while existing studies have investigated approaches to introducing and supporting argumentation (e.g., McNeill and Krajcik in Journal of Research in Science Teaching, 45(1), 53–78, 2008; Kang et al. in Science Education, 98(4), 674–704, 2014), few studies have investigated how game-based approaches may be used to introduce argumentation to students. In this paper, we report findings from a design-based study of a teacher’s use of a computer game intended to introduce the claim, evidence, reasoning (CER) framework (McNeill and Krajcik 2012) for scientific argumentation. We studied the implementation of the game over two iterations of development in a high school biology teacher’s classes. The results of this study include aspects of enactment of the activities and student argument scores. We found the teacher used the game in aspects of explicit instruction of argumentation during both iterations, although the ways in which the game was used differed. Also, students’ scores in the second iteration were significantly higher than the first iteration. These findings support the notion that students can learn argumentation through a game, especially when used in conjunction with explicit instruction and support in student materials. These findings also highlight the importance of analyzing classroom implementation in studies of game-based learning.
The purpose of this systematic review and meta-analysis was to gather, catalogue, assess, and evaluate the available evidence examining implicit beliefs about ability in the sport, physical activity, and physical education contexts. A total of 43 studies were found, of which 39 were subjected to meta analyses. With only 7 experimental studies, the strength of evidence is moderate, and the field would benefit from greater experimental work. Overall, incremental beliefs were moderately associated with a small group of theoretically derived correlates, while entity beliefs were only weakly associated. The field would benefit from expanding these outcomes to include a wider range of pertinent outcomes. Researchers should focus their efforts on systematically exploring the most powerful ways of inducing adaptive implicit beliefs with the aim of providing solutions to significant problems such as preventing dropout from organised sports, improving academic grades in and beyond physical education, and increasing levels of physical activity. 相似文献
Although adoptees are often stigmatized for their nonnormative identity, adopted individuals must communicate with nonfamily members to integrate their adoptive identity into their definition of self. In the current study, adult adoptees (n = 25) were interviewed about their processes for disclosing their adoptive status in their social networks. Drawing upon communication privacy management (CPM) theory, inductive analyses demonstrated that adoptees created motivational and contextual criteria to enact privacy rules surrounding adoption. Adoptees maintained privacy to avoid messages of “difference,” insensitive comments, imperviousness, and negative opinions about adoption. Adoptees disclosed about their adoption to build relational closeness and to educate/advocate for adoption. These privacy decisions were undergirded by the societal assumption that families are biologically linked or the discourse of biological normativity (Suter et al., 2014). 相似文献
A slew of gruesome executions by terrorist groups in 2014–2015 renewed interest in the public relations strategies of terrorists. As a case in point, the Islamic State group’s escalating brutality reflects their efforts as a relatively nascent extremist group to ensure a high and sustained volume of media coverage, especially among Western outlets. But what characteristics of events actually prompt coverage from major U.S. news media? Using a rich data set of terrorist incidents and coverage from six major broadcast and cable U.S. networks, we model coverage of terrorist incidents as a function of event proximity from U.S. soil, target country affinity with the United States, number of total and U.S. casualties, and the characteristics of the terrorist group. Our findings largely corroborate expectations set forth by the literature on norms and routines of journalism and economics of news. When it comes to terrorism, coverage by U.S. major media outlets is largely dependent on proximity to and affinity with the United States, weapons of mass destruction, and the number of global and U.S. casualties. 相似文献
Twenty first graders and twenty second graders were examined on skills in segmenting, reading, and spelling 50 words with regular and exceptional spelling patterns. By using the same words for each task, it was possible to assess the interrelationships among these skills on a word by word, child by child basis. A multivariate analysis of variance was conducted on difference scores among segmentation, reading, and spelling. Generally, differences favored segmentation and were maximized when final sounds were deleted and minimized when medial sounds were deleted. In addition, graphical analyses showed a greater probability of correct reading and spelling given correct segmentation than incorrect segmentation. Results were interpreted to support a computational notion of phonology as a prerequisite to reading and spelling, with a more reflective notion explaining the reciprocal relation between reading and segmentation of consonant blends and medial sounds. 相似文献
This research describes an intensive study undertaken to determine children's representational strategies for relational numbers
(e.g. proportions, ratios, fractions). Relational numbers have three quantities associated with them: a whole and two parts.
Given these three quantities, children can form a representation based on a part-whole relationship or on a part-part relationship.
Fifteen children (6th, 7th, and 8th graders) solved fifteen probability problems which varied information content and quantitative
relationships between the quantities expressed in the problems. A quantitative and qualitative analysis revealed that children
prefer a part-part representation to solve problems with relational quantities. 相似文献
This study explored the effects of processing texts in print or digitally on readers' comprehension, processing time, and calibration. Eighty-six undergraduates read print and digital versions of book excerpts about childhood ailments presented in counterbalanced order. Comprehension was tested at three levels (i.e., main idea, key points, and other relevant information). Direct comparisons between print and digital reading demonstrated a significant advantage for reading in print on students' recall of key points and other relevant information but not the main idea. When processing time was added as a mediator variable, it significantly affected the relation between medium and comprehension for all question levels. In terms of calibration, students read more quickly and judged their performance higher when engaged digitally, although their actual performance was much better when reading in print. Implications of these findings for subsequent research are considered. 相似文献
