This study examines the relationship between English as a second language (ESL) learners' depth of vocabulary knowledge, their lexical inferencing strategy use, and their success in deriving word meaning from context. Participants read a passage containing 10 unknown words and attempted to derive the meanings of the unknown words from context.…

Adult Spanish second language (L2) learners of English and native speakers of English participated in an English perception task designed to investigate their ability to use L2 acoustic-phonetic cues, e.g., aspiration, to segment the stream of speech into words. Subjects listened to a phrase and indicated whether they heard, e.g., "keep sparking…

The return to drug seeking, even after prolonged periods of abstinence, is a defining feature of cocaine addiction. The neural circuitry underlying relapse has been identified in neuropharmacological studies of experimental animals, typically rats, and supported in brain imaging studies of human addicts. Although the nucleus accumbens (NAcc),…

Monitoring the learning process in computer supported collaborative learning (CSCL) environments is a key element for supporting the efficacy of tutor actions. This article proposes an approach for analysing learning processes in a CSCL environment to support tutors in their monitoring tasks. The approach entails tracking the interactions within…

Turner syndrome, a genetic disorder that affects only females, can cause various physical, emotional, and educational disabilities. This disorder may go undiagnosed until school age or later. Short stature and lack of spontaneous puberty are common characteristics and can lead to teasing by peers. Some experience attention deficit and the…

This study describes responsibilities and training needs of paraeducators in physical education. Paraeducators (n = 138) employed in 34 midwestern schools received a 27-item questionnaire. Of the 138 paraeducators contacted, 76 responded, resulting in a 55.1% response rate. Only 16% of the total respondents (n = 76) reported receiving specific…

This study examines how teachers' use of affective strategies (voice intonation, dramatization, personal involvement comments) during the reading and discussion of books influence young children's affective reactions (dramatization, personal engagement, language play comments). Twenty kindergarten teachers read four books, two fiction and two…

This study investigates how the combination of instructor modeling and question prompts for peer-questioning influences students' online questioning and answering activities. Fourteen students in a turfgrass management online class at a large land-grant university participated in two three-week sessions of online discussion. Two randomly selected…

The purpose of this exploratory study was to examine the effectiveness of learner manipulation of visuals with and without organizing cues in computer-based instruction on adults' factual, conceptual, and problem-solving learning. An instructional unit involving the physiology and the anatomy of the heart was used. A post-test only control group…

A pretest-posttest control group design with random assignment, together with qualitative data collection and analysis, was used to investigate whether metacognitive, cognitive, and affective-awareness cues embedded in a hypermedia program could facilitate college students' near and far transfer problem solving in biology learning. It was assumed…

Eighty-three Test of English as a Foreign Language™ (TOEFL®) CBT writing prompts that were administered between July 1998 and August 2000 were examined in order to identify differences in scores that could be attributed to the response mode chosen by examinees (handwritten or word processed). Differences were examined statistically using…

Addressing theoretical and methodological issues, the present study assessed the content, accuracy, and consistency of school-aged children's memories of a potentially emotional, historic event: the explosion of the Space Shuttle Challenger on January 28, 1986. A total of 345 children in kindergarten through eighth grade were tested. To examine…

A case study examined one college student's poor performances during timed-writing sessions to develop a method to allow students to maintain the quality and ease in writing they achieve in other writing situations. The student, assigned to write a movie review, volunteered to participate in two 90 minute talk-aloud protocol sessions to examine…

In human speech, messages are conveyed to listeners through both verbal and vocal sources. Comparing verbal content-only with verbal plus vocal content permits assessment of the contribution of vocal cues in spoken messages. This study involved evaluations of physicians interacting with patients via the telephone. Thirty doctor-patient…

Twenty male and 20 female first graders were trained in a paired-associates (PA) learning task to test the hypothesis that instructions to generate interactive mental images of word referents and interactive imagery training administered prior to PA learning facilitate cued recall. Subjects were randomly assigned to one of the following five…
