Yeh, Shiou-Wen; Lo, Jia-Jiunn – Computers & Education, 2009
Giving feedback on second language (L2) writing is a challenging task. This research proposed an interactive environment for error correction and corrective feedback. First, we developed an online corrective feedback and error analysis system called "Online Annotator for EFL Writing". The system consisted of five facilities: Document Maker,…

Lo, Ya-yu; Chuang Wang; Haskell, Sherry – Journal of Special Education, 2009
This study investigated the effects of the "Scott Foresman Early Reading Intervention" (ERI) on growth rates in the early literacy skills of urban at-risk kindergarten students. Students participated in one of three groups: treatment-intensive/ strategic, treatment-benchmark, and nontreatment-benchmark. Treatment group students received…

Peer reviewedBorg, Walter – Educational Researcher, 1984
To rule out threats to internal validity, proposes a control group design in which control group subjects are given an alternate treatment that they perceive as equally desirable to and that is similar in duration and procedures to the experimental treatment but that is concerned with dependent variables unrelated to the experimental treatment.…

Peer reviewedVoorhees, James – Adolescence, 1981
The major aim of the present investigation was to determine if delinquent youths show neuropsychological deficits on the Lurias' Neuropsychological Investigation. Of the 11 general categories examined, only two, cutaneous and kinesthetic functions, did not statistically discriminate between a sample of 28 subjects from a California juvenile…

Schroeder, Stephen T.; Hovell, Melbourne F.; Kolody, Bohdan; Elder, John P. – Journal of Applied Behavior Analysis, 2004
The managers of beach businesses were randomly assigned to receive no intervention or two newsletters per week for 6 weeks that presented economic consequences of damage to coastal water quality and how to contact politicians. The percentage of proenvironmental political contacts was significantly greater in the experimental (newsletter) group…

Peer reviewedTamm, Leanne; Menon, Vinod; Ringel, Jessica; Reiss, Allan L. – Journal of the American Academy of Child and Adolescent Psychiatry, 2004
Objective: Response inhibition deficits are characteristic of individuals with attention-deficit/hyperactivity disorder (ADHD). Previous functional magnetic resonance imaging (fMRI) studies investigating the neural correlates of this dysfunction have used block designs, making it difficult to disentangle activation differences specifically related…

Wininger, Steven R. – Teaching of Psychology, 2005
Two studies supported the efficacy of a structured method for providing students with feedback on exams and means of using the teaching potential of exams, collectively referred to as formative summative assessment (FSA). In the first study, students responded positively to the method. In the second study, students enrolled in 2 sections of…

Elhoweris; Mutua, Kagendo; Alsheikh, Negmeldin; Holloway, Pauline – Remedial and Special Education, 2005
This study examines the effect of students' ethnicity on teachers' educational decision making. A total of 207 elementary school teachers from a large midwestern city participated in this study. All participants were randomly assigned to one of three treatment conditions. Each group was provided with a short case vignette describing a gifted…

Peer reviewedPalmer, Susan B.; Wehmeyer, Michael L.; Gipson, Krista; Agran, Martin – Exceptional Children, 2004
Although participation and progress in the general curriculum is mandated for all students, models to achieve such access often neglect students with more severe disabilities. Promoting self-determination linked to standards is an entry point to ensuring access to the general curriculum for all students, including students with severe…

Sigmundsson, H. – Brain and Cognition, 2005
This study was set out to explore the prediction that dyslexics would be likely to have particular problems compared to control group, on response time task when 'driving' a car simulator. The reason for doing so stems from the fact that there is considerable body of research on visual processing difficulties manifested by dyslexics. The task was…

Morrongiello, B.A.; Sedore, L. – Journal of Applied Developmental Psychology: An International Lifespan Journal, 2005
Many injuries occur to school-age children when they are allowed independence in decisions about risk taking during play. The present study examined the influence of child attributes (sensation seeking, typical emotional responses in risk situations) and social-situational context (peer presence) on risk taking. Children in the Experimental Group…

O'Riordan, Michelle – Autism: The International Journal of Research and Practice, 2004
Recent studies have suggested that children with autism perform better than matched controls on visual search tasks and that this stems from a superior visual discrimination ability. This study assessed whether these findings generalize from children to adults with autism. Experiments 1 and 2 showed that, like children, adults with autism were…

Reilly, Nicole; Cannizzaro, Michael S.; Harel, Brian T.; Snyder, Peter J. – Brain and Cognition, 2004
We sought to profile the voice acoustical correlates of simulated, or feigned depression by neurologically and psychiatrically healthy control subjects. We also sought to identify the voice acoustical correlates of feigned sleepiness for these same subjects. Twenty-two participants were asked to speak freely about a cartoon, to count from 1 to 10,…

Gerber, Bertram; Giurfa, Martin; Guerrieri, Fernando; Lachnit, Harald – Learning & Memory, 2005
Blocking occurs when previous training with a stimulus A reduces (blocks) subsequent learning about a stimulus B, when A and B are trained in compound. The question of whether blocking exists in olfactory conditioning of proboscis extension reflex (PER) in honeybees is under debate. The last published accounts on blocking in honeybees state that…

Bernstein, Larry; Yamaguchi, Ryoko; Unlu, Fatih; Edmunds, Julie; Glennie, Elizabeth; Willse, John; Arshavsky, Nina; Dallas, Andrew – Society for Research on Educational Effectiveness, 2010
The purpose of this study is to rigorously examine the implementation and impact of the Early College High School (ECHS) model in North Carolina. The primary goal of the ECHS model is to increase the number of students who graduate from high school and who continue on and succeed in college. Therefore, the anticipated long-term outcomes for the…
