Individual strategies in a spatial task and how they relate to aptitudes

Thirty-two subjects were first submitted to a series of aptitude tests, then participated in a mental rotation task with advance information (Cooper, 1975), and finally gave retrospective reports about their solution strategy. The verbal reports showed that different subjects used different strategies to perform the rotation task, and also that some subjects shifted strategies, in that they successively adopted several ways of processing the same task. The coding of verbal reports led to distinguish five types of strategies (called rotation, partial rotation, verbal, projection, multiple). Five groups of subjects using preferentially one of these strategies were constituted. For each group hypotheses on performance were tested via analyses on reaction times and errors. These analyses confirmed that the five strategy groups produced different patterns of RT in conformity with verbal reports. Moreover the comparison of the mental aptitude profiles across the different strategy groups suggests that strategy choices are affected by steady and general characteristics of cognitive functioning.     

Students' knowledge construction in small groups in the seventh grade biology laboratory: Verbal communication and physical engagement

Same- and mixed-gender small groups of middle school, seventh grade, students were observed gathering data on knowledge construction in terms of verbal communication and physical engagement in the biology laboratory. Video cameras with wireless receivers were used to record interactions between students in groups of four (36 target subjects in total). Both quantitative and qualitative methods were employed to examine how students exchange ideas, construct scientific concepts and perform laboratory work during laboratory sessions. Results indicated that gender differences exist in several verbal communication and physical engagement behaviour measures regardless of the same-gender or mixedgender groups. However, one or two students in either all-boy or all-girl groups were dominant in their small groups' verbal communication and physical engagement, which suggested that individual differences also existed in the same-gender groups. It also showed girls working in the mixed-gender groups appeared to participate on a par with boys in the majority of engagement and verbal communication behaviours. However, more detailed analysis revealed that verbal communication and physical engagement patterns varied widely within the three mixed-gender groups. This study strongly suggested that girls have the potential to perform equally well as boys in the science laboratory and both individual and gender differences contribute to the students' differential verbal communication and laboratory engagement.     

Structural invariance in the associations of naming speed,phonological awareness,and verbal reasoning in good and poor readers: A test of the double deficit hypothesis

The associations of multiple measures of speeded naming, phonological awareness, and verbal intelligence with word reading were examined in 51 poor readers and 74 good readers in third and fourth grade. Structural equation modeling was used to determine the extent to which these two groups exhibited structurally invariant patterns of associations among the constructs. Results revealed that for poor readers, both speeded naming and phonological awarencess were significantly associated with word reading, but verbal intelligence had no association with it. In contrast, for good readers, phonological awareness and verbal intelligence were significantly associated with word reading, but naming speed was not. Findings are discussed in light of the double deficit hypothesis.     

Pupil Talk in Biology Practical Work‐‐a preliminary study

The development of a framework for analysing pupil talk is described and the reliability of scoring transcribed conversations using the framework discussed. Preliminary findings from this study on the talk occurring during small group practical work in biology focus on the forms of verbal interaction that occur, patterns of verbal interactions shown by individuals within groups and the possible link between such patterns and roles within the groups.     

Patterns of Response: A Case Study of Elementary Students With Spatial Strengths

Gifted students with spatial strengths have areas of remarkable talent but are often overlooked, underidentified, and underserved in American schools. Their preference for learning through imagistic reasoning conflicts with traditional verbal instructional techniques typically used in schools. To better serve these students who have the potential to be leaders in the fields of engineering, physics, and mathematics, it is important to develop an awareness of their learning patterns and problem-solving processes. The purpose of this case study was to examine, understand, and compare patterns of response in six students, three with spatial strengths and three with verbal strengths, as they solved spatial problems, responded to questions about their preferred learning style, and indicated their instructional preferences. A qualitative research design used structured interviews and observations to investigate the learning preferences of fourth-grade students with spatial strengths and to contrast their patterns of response to students lacking exceptional ability in spatial reasoning. Based on the selective coding, visual ideation, innovation, and holistic processing emerged as predominant themes in this research.     

The WISC-R and evidence of item bias for native-American Navajos

The study investigated cultural bias in the 79 items of the three verbal tests of the Wechsler Intelligence Scale for Children-Revised (WISC-R). The Information, Similarities, and Vocabulary subtests were administered to 40 Anglo and 40 Native- American Navajo subjects matched for grade level. The responses of the two groups of subjects on individual items were analyzed by log-linear technique using the likelihood ratio chi-square statistic. The findings revealed that performance of subjects was homogeneous across groups on most of the items of three verbal subtests of the WISC-R. Only 15 (19%) of the 79 items comprising Information, Similarities, and Vocabulary subtests were found to be biased against the Navajo sample. Five of these items are from the Information, four from the Similarities, and the remaining six items are from the Vocabulary subtest. Implications of these findings for the psychoeducational assessment of minority children were discussed.     

Effect of cooperative learning strategies on student verbal interactions and achievement during conceptual change instruction in 10th grade general science

This study evaluated the effects of cooperative learning on students' verbal interaction patterns and achievement in a conceptual change instructional model in secondary science. Current conceptual change instructional models recognize the importance of student–student verbal interactions, but lack specific strategies to encourage these interactions. Cooperative learning may provide the necessary strategies. Two sections of low-ability 10th-grade students were designated the experimental and control groups. Students in both sections received identical content instruction on the particle model of matter using conceptual change teaching strategies. Students worked in teacher-assigned small groups on in-class assignments. The experimental section used cooperative learning strategies involving instruction in collaborative skills and group evaluation of assignments. The control section received no collaborative skills training and students were evaluated individually on group work. Gains on achievement were assessed using pre- and posttreatment administrations of an investigator-designed short-answer essay test. The assessment strategies used in this study represent an attempt to measure conceptual change. Achievement was related to students' ability to correctly use appropriate scientific explanations of events and phenomena and to discard use of naive conceptions. Verbal interaction patterns of students working in groups were recorded on videotape and analyzed using an investigator-designed verbal interaction scheme. The targeted verbalizations used in the interaction scheme were derived from the social learning theories of Piaget and Vygotsky. It was found that students using cooperative learning strategies showed greater achievement gains as defined above and made greater use of specific verbal patterns believed to be related to increased learning. The results of the study demonstrated that cooperative learning strategies enhance conceptual change instruction. More research is needed to identify the specific variables mediating the effects of cooperative learning strategies on conceptual change learning. The methods employed in this study may provide some of the tools for this research.     

Multidimensional ability tests and culturally and linguistically diverse students: Evidence of measurement invariance

Ability tests are used by teachers to provide additional context for interpreting student achievement and as a tool for differentiating instruction to the cognitive strengths and weaknesses of students. Tests that provide the most useful information for these purposes measure school-related content domains including verbal and quantitative reasoning. However, there is concern that verbal content affects validity for culturally and linguistically diverse students. In this study, the structure of a multidimensional ability test of verbal, quantitative, and nonverbal reasoning skills was explored in three groups of students who varied in language and cultural background. Configural invariance and invariant factor loadings were supported, but the verbal battery showed weaker relationships to the other batteries and reduced variability for English learners. Results indicate that battery-level scores are appropriate for all students, but that accounting for educational opportunity may be required for interpreting scores.     

An analytical framework for analyzing student teachers’ verbal interaction in learning situations

This paper focuses on the study of student teachers’ verbal interaction in learning situations generated in a classroom corresponding to a mathematics methods course. In our work, we incorporate two ‘ways of seeing’ a group: as an entity or as a set composed of individualities. We present an analytical framework that considers two dimensions connected with these ways of seeing the group and four variables corresponding to these dimensions, through which the verbal interaction between student teachers in a group can be considered. As regards the first dimension, the variables included are specific language, cognitive processing, social processing; the second dimension considers the relational variable. We describe each of the different variables that form the framework, and how this framework allows us to analyse the verbal interaction in three groups of student teachers. We believe that building analytic frameworks that allow the study of verbal interaction in detail is worthwhile in the educational field due to their important role in the analysis of learning-teaching processes.     

Temporal resolution of auditory perception and verbal working memory in 15 children with language impairment

We investigated temporal resolution of auditory perception (TRAP), verbal working memory, and speech perception in 15 children with language impairment (LI) in comparison with a control group of 99 typical children. A computerized two-choice test was used to assess these three abilities. No deficits in TRAP were found in the LI group, and the thresholds were similar for both study groups. It was interesting that the variability was high for both groups and that the control group's performance was poorer than reported in some previously published studies. There were significant differences in the two groups' performance on speech perception and verbal working memory. Working memory was the most sensitive of these two measures.     

Underachievement in the verbally gifted: Implications for pedagogy

An ecological-systems view is presented describing academic underachievement in highly verbal, gifted adolescents. The highly verbal are considered to be those children who show a precocious ability to comprehend, analyze, and synthesize written material, as well as an attitudinal predisposition toward less structured, more creative verbal tasks. Underachievement is discussed in terms of global versus analytic processing styles, intrinsic versus extrinsic motivation, verbal versus quantitative interests and abilities, and the concomitant achievement patterns. It is argued that a unique pattern of interests, motives, and cognitive styles results in a differential pattern of achievement for these youth. Underachievement is viewed as a mismatch between the school's curriculum and testing procedures and these children's unique needs and stylistic approaches toward learning. The implications for psychoeducational assessment, pedagogy, and counseling are discussed.     

Cognitive development in bilingual and monolingual lower-class children

The cognitive development of lower-class English-speaking monolingual and English-Spanishs peaking bilingual children in kindergarten, third, and sixth grades was compared by means of standard verbal and nonverbal measures. The verbal ability of bilingual children was assessed in both English and Spanish. Their scores in both languages were lower than those of monolingual children. However, the mean scores and error patterns of both groups on nonverbal measures were equivalent, suggesting that bilingual and monolingual children have comparable cognitive skills despite apparent language differences.     

The significance of discrepancies between the verbal and non-verbal intelligence scores of a group of first year university students

The object of the study was to investigate the significance of the differences between verbal and non-verbal scores on the New South African Group Intelligence Test (NSAGT).The experimental subjects were first year university students. They were subdivided into three groups: one group whose non-verbal scores were higher than their verbal scores, a second group whose verbal scores were higher than their nonverbal scores and a third group, acting as a control group, whose verbal and nonverbal scores were approximately equal.The three groups were compared with regard to such features as visual and auditory acuity, personal adjustment and academic achievement. The raw data were arranged in three-dimensional contingency tables and interrelationships between variables were computed by means of the G² test.A positive correlation was found between temperamental personality features and high non-verbal scores on the NSAGT.This article is based on the MA dissertation of the second author under the supervision of the first author. The study was partly sponsored by a grant from the Human Sciences Research Council. Republic of South Africa, to which body grateful acknowledgement is made. However, the opinions expressed and the conclusions drawn are the absolute responsibility of the authors     

The Swedish WAIS-R factor structure and cognitive profiles for adults with dyslexia

Factor analysis of the Swedish version of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) on a group of 88 adult individuals with dyslexia showed a three-factor structure with a verbal comprehension (VC) factor, a perceptual organization (PO) factor, and a freedom from distractibility (FD) factor. The results of this factor analysis support earlier findings from factor analyses of adults in the original U.S. normative sample and in different clinical groups. The profile of scores for the sample of individuals with dyslexia showed the expected pattern, with PO highest and FD lowest. The predicted pattern was also observed using Bannatyne's recategorization of WAIS-R subtests. As has been true for other typical and exceptional samples, women scored significantly higher than men on the Digit Symbol subtest. Related to this gender difference, Digit Symbol scores proved to be sensitive to problems associated with dyslexia only for men with dyslexia. Also, education level was shown to be related to verbal (V)-performance (P) IQ discrepancy, with larger P > V differences observed for participants with fewer years of formal schooling. Regardless of these gender and education differences, the characteristic factor score and Bannatyne patterns were identified for both men and women and for three different subsamples categorized by educational level.     

EUROPEAN DISSERTATION SUMMARIES

Co‐operative learning means shared leadership where there is not just one leader in a group but where each member of the group is a leader. A leader demonstrates academic as well as collaborative skills in helping the group achieve a goal. Some academic skills are verbal interactions such as initiating ideas, responding by summarizing or suggesting procedures. Collaborative skills that build and maintain a good working relationship within the group include verbal interactions of praising group members and inviting others to get involved. The purpose of this study was to examine the verbal interactions and non‐verbal behaviours within unstructured learning groups. The verbal interactions were classified as positive if they aided the group to accomplish its goal and negative if they inhibited the group accomplishing its goal. Twenty‐eight students from seven intermediate‐grade level classrooms, grouped heterogeneously for sex and race and homogeneously for their ability in science, were selected for observation as they were doing a science activity. In general students’ verbal interactions were positive (i.e., there were more than four times more positive interactions than negative interactions). Further, in reviewing the positive interactions, students presented ideas more than four times as much as any of the other types of interactions. Females encouraged other members to participate in the activity significantly more than the males did. There was a trend in the number of times the equipment (clay) was handled; the males handled it more than the females as a function of race. Qualitative analyses revealed consistent patterns of interactions within groups of black and white males and females.     

English Language Proficiency and Bilingual Verbal Ability Among Chinese,Dominican, and Haitian Immigrant Students

This article describes English language proficiency and bilingual verbal ability for a sample of 209 students aged 10 to 16 from three immigrant groups—Chinese, Dominican, and Haitian. Sources of data included structured student interviews, parent interviews, and individual language assessments. On average, students' English language proficiency was far below their age and grade level with significant differences among the groups. Estimates of students' language ability improved once their skills in their first language were considered as demonstrated by the bilingual verbal ability scores. Results from this study demonstrate the need to consider both English and first language skills in assessing the language abilities of these students and in promoting educational access and equity for recent immigrants.     

The interrelationships among preschool predictors of reading acquisition for German children

A sample of 169 German children were tested in general verbal ability, verbal memory span, phonological awareness, lexical access speed and accuracy, and letter knowledge in preschool. These tests were used as independent measures predicting performance on second grade reading comprehension, word discrimination, and word decoding speed. Tests of verbal ability, memory capacity, and phonological awareness were also given over a year later in elementary school. After determining that the influence of verbal ability, memory capacity, and phonological awareness on reading comprehension was comparable when measured in preschool and elementary school, the effects of all preschool measures on the three dependent reading measures were assessed. These analyses revealed differential main effects and interactions for the three dependent measures. However, a significant three-way interaction among lexical access, memory capacity, and phonological awareness was found for all three reading measures. These results indicate that the interaction and subsequent effects of these linguistic skills precedes and influences reading acquisition. This is contrary to the view that these skills interact as a result of reading experience. The implications of these results, as well as comparisons of conducting such studies with German rather than English speaking children are discussed.     

THE CLASS‐SIZE EFFECT UPON ACTIVITY AND COGNITIVE DIMENSIONS OF LESSONS IN HIGHER EDUCATION

This study examines the effects of class size upon the verbal interactions and the cognitive level of medical instruction. The major findings of this study indicate that: (a) the percentage of the teacher's verbal activities increases with the group size; (b) the shortest teacher‐lectures are given in medium‐size classes; (c) the longest student‐answers and student initiations are observed in medium‐size classes; (d) the maximal diversity of verbal interactions is found in medium groups, while the minimal is found in large groups; (e) the percentage of interactions at the lowest cognitive level (knowledge) increases with class size; (f) longer interactions are observed in large classes at the knowledge level, and in smaller classes at the analysis and evaluation levels; (g) the minimal cognitive diversity is found in large groups; (h) both activity and cognitive total scores decrease as the class size increases. The implications of these findings are discussed.
