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).     

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     

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.     

The Effect of Test Translation on the Performance of Second Grade English Learners on the KeyMath‐3

This study was conducted to determine whether Spanish‐enhanced administration of a standardized math assessment would result in improved scores for English Learners who used Spanish as a heritage language. Twenty‐one typically developing second‐graders (English Learners) were administered the traditional KeyMath‐3. If the child made an error on an item, a Spanish version of the item was presented. Difference scores were calculated to determine whether the Spanish‐enhanced version resulted in improved scores. Data were analyzed using paired t‐tests and simple regression. The data results showed that all children significantly benefited from the Spanish‐enhanced administration of items answered incorrectly in English. The amount of benefit was predicted by a child's degree of Spanish dominance. It was concluded that standardized math tests that do not accommodate second‐language learners may be inadvertently testing language skills in addition to math skills. Implications for assessment and interpretations of assessments are discussed.     

Globalization and the freedom of knowledge

This article considers the transmission of knowledge in higher education. It takes the metaphor of the music industry that pre‐selects the music people can buy. The sales potential is the leading principle in the selection process. Often the small producer is excluded because his or her music is not of commercial interest. The end‐customer does not know what he or she is missing because he or she has never heard the music. It is to be feared that a similar market principle will also influence the selection of knowledge and affect the capacity of higher education institutions to freely generate and transmit new knowledge. The globalization of higher education risks homogenizing the cultural traditions of the non‐Western world through a process of Western cultural domination. On the other hand, the Internet, via open source software like LINUX, might serve to democratize higher education and allow greater grassroots input.     

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.
