Characteristics of SAT Quantitative Items Showing Improvement After Coaching Among Black Students From Low-Income Families: An Exploratory Study

The present exploratory investigation is an extension of a 1985 study that evaluated a Scholastic Aptitude Test preparation program involving black urban students. The present study was conducted to determine if there are identifiable characteristics of quantitative items associated with a susceptibility to coaching. Items showing p-value improvements of. 10 after coaching were compared with items not showing such improvements; comparisons were made in terms of the content, type. format, level of cognitive requirement, and position of the items. Items showing improvement were found across content areas, formats, and type. Findings are discussed in relation to the usefulness and improvement of well-designed supplemental instructional programs that have the potential to affect criterion performance in mathematics     

Exploring the Metafictive in Elementary Students' Writing

Although some researchers have examined students' literary understandings of and responses to books with metafictive characteristics, few have explored how elementary students incorporate metafictive devices into their writing. In this article I analyse the stories and books created by a class of Grade 5 students and discuss the metafictive devices evident in their work. In addition to considering how the literature students read and how the classroom interpretive community influenced the students' stories/books, I discuss some broader issues about the significance of students reading and writing metafictive texts.     

Effectiveness of Spanish intervention for first-grade English language learners at risk for reading difficulties

The effectiveness of an explicit, systematic reading intervention for first-grade students whose home language was Spanish and who were at risk for reading difficulties was examined. Participants were 69 students in 20 classrooms in 7 schools from 3 districts who initially did not pass the screening in Spanish and were randomly assigned within schools to a treatment or comparison group; after 7 months, 64 students remained in the study. The intervention matched the language of instruction of their core reading program (Spanish). Treatment groups of 3 to 5 students met daily for 50 min and were provided systematic and explicit instruction in oral language and reading by trained bilingual intervention teachers. Comparison students received the school's standard intervention for struggling readers. Observations during core reading instruction provided information about the reading instruction and language use of the teachers. There were no differences between the treatment and comparison groups in either Spanish or English on any measures at pretest, but there were significant posttest differences in favor of the treatment group for the following outcomes in Spanish: Letter-Sound Identification (d = 0.72), Phonological Awareness composite (d = 0.73), Woodcock Language Proficiency Battery-Revised Oral Language composite (d = 0.35), Word Attack (d = 0.85), Passage Comprehension (d = 0.55), and two measures of reading fluency (d = 0.58-0.75).     

Acquisition of Complex Systemic Thinking: Mental Models of Evolution

We investigated the impact of introducing college students to complex adaptive systems on their subsequent mental models of evolution compared to those of students taught in the same manner but with no reference to complex systems. The students' mental models (derived from similarity ratings of 12 evolutionary terms using the pathfinder algorithm) were significantly similar to their teachers' mental models and were correlated to their performance on an essay on evolution. Introducing students to complex systems facilitated their understanding of the mechanism of inheritance, the mechanism of evolution, and the role of chance in evolution.     

VI. Patogenia

De la exposición histórica que hemos dado ya, se desprenden dos concepciones principales que pueden resumir los mecanismos patogenéticos de la afasia. Una es la neurológica y la otra la psicológica.     

Individual Education Plans Revisited: A Review of the Literature

Considerable attention and debate has surrounded the implementation of individual education plans (IEPs) for students with special needs during the past two decades. It is, therefore, timely to revisit the IEP process and examine the nature of the debate. In this paper, literature is reviewed to identify what has been learned from implementation of the IEP process and to highlight remaining questions about IEP efficacy and utility. The phases of evolution of the IEP process described by Smith (1990b) provide a framework for reviewing the literature. Issues requiring attention are highlighted and directions for further research are identified.
