Reading comprehension,working memory and higher-level language skills in children with SLI and/or dyslexia

This study examined (1) whether working memory and higher-level languages skills—inferencing and comprehension monitoring—accounted for individual differences among Chinese children in Chinese reading comprehension, after controlling for age, Chinese word reading and oral language skills, and (2) whether children with specific language impairment (SLI) or dyslexia showed deficits in these skills. Eighty-two Cantonese Chinese-speaking children between the age of 7; 8–9; 5 were assessed. Regression analyses on the full sample offered support for the first question. The children were also classified into four groups: Typically-developing (TD; N = 34), specific language impairment-only (SLI-only; N = 18), SLI-dyslexia comorbid (SLI-D; N = 22) and dyslexia-only (D-only; N = 8). Pair-wise comparisons focusing on the second question revealed that both the SLI-only and the D-only group performed worse than the TD group in reading comprehension after controlling for age and nonverbal intelligence. The SLI-only and the D-only group showed a different profile of deficits: only the SLI-only group performed worse than the TD group in working memory, comprehension monitoring, and inferencing. The SLI-D comorbid group did worse than the SLI-only, but not the D-only group, in reading comprehension. The SLI-D comorbid group did not do worse than either single diagnosis group in the higher-level language skills associated with reading comprehension. These findings suggested adopting different intervention approaches for reading comprehension difficulties in children with SLI versus children with dyslexia.     

Transfer of reading-related cognitive skills in learning to read Chinese (L1) and English (L2) among Chinese elementary school children

This study investigated transfer of reading-related cognitive skills between learning to read Chinese (L1) and English (L2) among Chinese children in Hong Kong. Fifty-three Grade 2 students were tested on word reading, phonological, orthographic and rapid naming skills in Chinese (L1) and English (L2). The major findings were: (a) significant correlations between Chinese and English measures in phonological awareness and rapid naming, but not in orthographic skills; (b) significant unique contribution of Chinese and English rapid naming skills and English rhyme awareness for predicting Chinese word reading after controlling for all the Chinese and English cognitive measures; (c) significant unique contribution of English phonological skills and Chinese orthographic skills (a negative one) for predicting English word reading after controlling for all the English and Chinese cognitive measures; and (d) significant unique contribution of Chinese rhyme awareness for predicting English phonemic awareness. These findings provide initial evidence that developing reading-related cognitive skills in English may have facilitative effects on Chinese word reading development. They also suggest that Chinese orthographic skills or tactics may not be helpful for learning to read English words among ESL learners; and that Chinese rhyme awareness facilitates the development of English phonemic awareness which is an essential skill predicting ESL learning.     

Introducing a scalable peer feedback system for learning teams

In the current research, we report on a peer feedback system for supporting student teamwork skill development during post-secondary education. The peer feedback system is part of a larger suite of assessments at ITPmetrics.com. This is a free assessment-based system that allows team members to provide round-robin ratings of each member’s effectiveness in the team on five dimensions (communication; commitment; foundation of knowledge, skills and abilities; emphasising high standards; and focus), as well as provide anonymous written feedback to supplement the numeric scores. Team members have access to a dashboard where they can complete the assessment and store assessment reports generated from their peers’ ratings. We summarise data from student learning teams suggesting that peer ratings are reliable (internally consistent, unidimensional and inter-rater correlated; n?>?85,000). Recommendations for implementation are provided with respect to pre-briefing, debriefing, and assessment schedules.     

Response to Intervention: Following Three Reading Recovery Children on Their Individual Paths to Becoming Literate

Research Findings: In the United States a shift has occurred in how children are identified for long-term special education services. Since 2004, U.S. funding for special education services has included a provision for early intervention services, focusing on the importance of providing supplemental instructional opportunities to students who are not successful in learning from the core classroom instruction. Commonly referred to as response to intervention, this model involves educators monitoring how well students respond to intervention instruction, with referral for special education services for those who make little progress. Practice or Policy: In this article, we propose that intervention instruction should be responsive to the learner as well as focus on how well the learner responds to the intervention. Given that contextual circumstances, including instructional experiences, impact the child's literacy achievement, providing intervention instruction that is contingent upon each child's literacy strengths and needs is the best way to ensure each child's successful response to intervention instruction. As an example of an intervention using responsive instruction, this article describes different instructional approaches provided by Reading Recovery teachers with 3 children who were initially the lowest readers and writers in their classes. All 3 children were able to progress to on-grade-level reading and writing proficiency as a result of the intervention.     

Competency-Based Reforms of the Undergraduate Biology Curriculum: Integrating the Physical and Biological Sciences

The National Experiment in Undergraduate Science Education project funded by the Howard Hughes Medical Institute is a direct response to the Scientific Foundations for Future Physicians report, which urged a shift in premedical student preparation from a narrow list of specific course work to a more flexible curriculum that helps students develop broad scientific competencies. A consortium of four universities is working to create, pilot, and assess modular, competency-based curricular units that require students to use higher-order cognitive skills and reason across traditional disciplinary boundaries. Purdue University; the University of Maryland, Baltimore County; and the University of Miami are each developing modules and case studies that integrate the biological, chemical, physical, and mathematical sciences. The University of Maryland, College Park, is leading the effort to create an introductory physics for life sciences course that is reformed in both content and pedagogy. This course has prerequisites of biology, chemistry, and calculus, allowing students to apply strategies from the physical sciences to solving authentic biological problems. A comprehensive assessment plan is examining students’ conceptual knowledge of physics, their attitudes toward interdisciplinary approaches, and the development of specific scientific competencies. Teaching modules developed during this initial phase will be tested on multiple partner campuses in preparation for eventual broad dissemination.     

Are poor Chinese text comprehenders also poor in written composition?

We studied the performance in three genres of Chinese written composition (narration, exposition, and argumentation) of 158 grade 4, 5, and 6 poor Chinese text comprehenders compared with 156 good Chinese text comprehenders. We examined text comprehension and written composition relationship. Verbal working memory (verbal span working memory and operation span working memory) and different levels of linguistic tasks—morphological sensitivity (morphological compounding and morphological chain), sentence processing (syntax construction and syntax integrity), and text comprehension (narrative and expository texts)—were used to predict separately narrative, expository, and argumentation written compositions in these students. Grade for grade, the good text comprehenders outperformed the poor text comprehenders in all tasks, except for morphological chain. Hierarchical multiple regression analyses showed differential contribution of the tasks to different genres of writing. In particular, text comprehension made unique contribution to argumentation writing in the poor text comprehenders. Future studies should ask students to read and write parallel passages in the same genre for better comparison and incorporate both instructional and motivational variables.     

Program exclusivity and competition in the cable television industry

The authors argue that program exclusivity will be an important factor in the future of the cable television industry. They assert that prohibiting cable program exclusivity may limit the First Amendment rights of cable programmers and operators. The authors conclude that the best chance for increasing competition if program exclusivity continues is to increase the number of market participants.
