Enhancing Main Idea Comprehension for Students with Learning Problems: The Role of a Summarization Strategy and Self-Monitoring Instruction

Abstract: This study investigated the effectiveness of a main idea strategy and self-monitoring instructional procedure for improving comprehension of textual material in students with high-incidence (e.g., learning and behavioral) disabilities. Thirty-three middle school students with disabilities were randomly assigned to experimental and control groups. Students in the experimental condition were trained to identify and generate main idea statements using main idea strategy instruction and a self-monitoring procedure. Results indicated that the instructional procedures led to increased reading comprehension of students in the experimental group on the training measure, which was maintained over time. On near and far transfer measures, the experimental group statistically outperformed students in the control group on posttest and delayed posttest items requiring selection responses. Students in the experimental group maintained strategy usage 6 weeks later on selection type responses on the near transfer measure ...

Reliability and Validity of Parent and Teacher Ratings of Attention-Deficit/Hyperactivity Disorder Symptoms:

Abstract: The reliability and criterion-related validity of the Home and School versions of the AD/HD Rating Scale-IV were evaluated in a nonreferred sample of 71 students. Parent and teacher rat-ings were obtained 4 weeks apart at a time contemporaneous with observations of classroom behavior and academic productivity. Results indicated adequate levels of internal consistency, test-retest reliability, and cross-informant agreement for both parent and teacher ratings. Teacher ratings were significantly correlated with classroom observational data, and parent ratings were primarily related to behavior ratings. The discriminant validity of these scales also was examined in a sample of 92 clinic- referred children. Both the Home and School versions of the AD/HD Rating Scale-IV were found to discriminate significantly between children with and without AD/HD. The AD/HD Rating Scale-IV appears to have adequate psychometric properties for the screening and assessment of AD/HD.

The eyes have it

Abstract: This paper evaluates the impact of eye localization on face recognition accuracy. To investigate its importance, we present an eye perturbation sensitivity analysis, as well as empirical evidence that reinforces the notion that eye localization plays a key role in the accuracy of face recognition systems. In particular, correct measurement of eye separation is shown to be more important than correct eye location, highlighting the critical role of eye separation in the scaling and normalization of face images. Results suggest that significant gains in recognition accuracy may be achieved by focussing more effort on the eye localization stage of the face recognition process.
