The interdependence of language and translational math skills among bilingual hispanic engineering students

The performance of 43 Hispanic engineering and science majors on a task that consists of reading a sentence describing a mathematical relationship between two variables, and then writing an equation describing the relationship, is investigated in both English and Spanish. Results are compared with grade point average and with language proficiency. Comparison of the bilingual group to a monolingual group consisting of 52 engineering and science students shows that performance, as measured by either the mathematical translation task or grade point average, is more strongly correlated with language proficiency for the bilingual group. Clinical interviews conducted with samples from each group reveal large differences in the interpretation of the mathematical task between Hispanics and monolinguals. Suggestions are made for the improvement of the technical education of Hispanics.     

Increased consultation opportunities for school psychologists: A service delivery model

A model of delivery of services that enables school psychologists to meet testing demands while initiating a broad range of consultative services is described. Requirements of the model include: (a) having funds available for contract testing, (b) having conferences with teachers prior to formal referral of children, and (c) having qualified contract evaluators available. Benefits, as well as obstacles to be expected in implementing the model, are discussed.     

Special education placement decisions made by teams and individuals: A cross-cultural perspective

The present study looked at whether special education placement decisions made by teams are superior to those made by individuals. The investigation was conducted in Puerto Rico to determine whether the benefits of the cooperative group process exist in another culture. Results indicated that teams in Puerto Rico generated significantly less variability (i.e., errors) in their placement decisions than did the same specialists acting independently.     

Using the College Outcome Measures Project to measure college outcomes

This article describes one institution's use of the College Outcome Measures Project (COMP) in comparing outcomes for graduates of traditional and non-traditional programs. The study was designed to answer three questions concerning the use of COMP in evaluating traditional and non-traditional programs. Results obtained in a study of 96 University of Minnesota graduating seniors suggest greater potential usefulness in distinguishing among institutions than in comparing outcomes of programs within an institution. The authors conclude that as new approaches and instruments for measuring college outcomes become available, criteria for instrument selection need to be shared among individuals charged with conducting outcome studies.     

CS modality,context conditioning,and conditioned freezing

Two studies used a one-trial-a-day aversive conditioning procedure with rats as subjects to investigate the effects of a noise versus a light CS on conditioned freezing. Experiment 1 demonstrated that less conditioned freezing was elicited by the light, although the two CSs led to similar levels of freezing to the contextual cues of the conditioning chamber. Experiment 2 replicated these outcomes and showed that the manipulation of CS intensity produced results similar to those of modality, with the more intense CSs eliciting less freezing. The second experiment also determined that freezing to contextual cues resulted from context conditioning. According to the Rescorla-Wagner model, CSs that condition poorly should generate little competition with context conditioning. Since neither the modality nor intensity factor reliably influenced context conditioning, as measured by context-evoked freezing, the studies provide no support for the view that the effects on CS-evoked freezing represent differences in the strength of conditioning to the various stimuli. This finding raises the possibility that all of the CSs conditioned well but varied in their abilities to elicit freezing because they differed in terms of the form of defensive behavior under their control.     

Vaginal inspection as it relates to child sexual abuse in girls under thirteen

Inclusion of vaginal inspection in all physical examinations resulted in doubling identification of cases of child sexual abuse. Forty-five of 247 girls under 13 years of age were admitted because sexual abuse had been reported. Of the 202 girls not suspected, 45 additional cases of sexual abuse were discovered by suspicious findings on vaginal inspection. The horizontal diameter of the vaginal opening exceeding 4 mm correlated in three of four instances with a confirming history for past sexual abuse. It is recommended that physical examination of young girls routinely include inspection of the vaginal opening. Pediatric caregivers need to teach themselves the parameters of the normal to protect those children who are suffering sexual abuse in their environment.     

The effect of inquiry teaching and advance organizers upon student outcomes in science education

Two areas of research were explored in this meta-analysis: comparison of inductive versus deductive teaching approachs, and the use of advance organizers. This study involved the coding of 128 characteristics for 39 studies which spanned the period from 1957 through 1980. The coding variables included 57 which were concerned with features of the treatment while 12 were concerned with outcome attributes. Aspects such as research methodology, sample characteristics, and instructional experiences were examined quantitatively in terms of their relationships to the treatment effects through the use of a common metric for all studies. Mean effect sizes were calculated and reported.     

A comparison of personality attributes of science teachers and medical technologists

Undergraduate students who major in science make diverse career choices. Two such career choices are medical technologists and science teachers. One possible reason for science majors selecting different career choices might be attributed to varied personality dimensions. The purpose of this study was to identify a set of personality attributes that distinguish practicing medical technologists from practicing science teachers. The subjects of this study consisted of 83 medical technologists and 57 science teachers. Eysenck Personality (EPI) was utilized to investigate the personality attributes of subjects in terms of Eysenck's personality variable of Extroversion-Introversion and Neuroticism-Stability. Vocational Preference Inventory was utilized to investigate the vocational personality profile of subjects in terms of Holland's classification of occupations and work environment. Data with EPI revealed that there was no significant difference between medical technologists and science teachers with respect to Eysenck's personality variable of extroversion. However, there was found a significant difference between the two groups with respect to Eysenck's personality variable of neuroticism. Data with VPI revealed that there was no significant difference between medical technologists and science teachers with respect to Eysenck's personality variable of extroversion. Both the groups were characterized by the personality profile of IAS (Intellectual-Artistic-Social). This profile was different from that required earlier in literature.     

An investigation of oral language and writing proficiency in third-grade students

Over the years, professionals have hypothesized that a positive relationship exists between children's oral language proficiency and their written language performance. This study examined the following two aspects of the relationship between oral and written language: (a) Are specific linguistic components of language more closely related than others? (b) Do groups rated high, medium, or low on written language measures differ significantly in oral language proficiency? Measures of oral and written language were administered to 77 third-grade students. Results indicated that moderate relationships existed between grammatical aspects of oral and written language. Oral language proficiency was significantly different for groups rated high, medium, and low on the basis of written language performance.
