A Cognitive Approach to the Development of Early Language

A controversial issue in the field of language development is whether language emergence and growth is dependent solely on processes specifically tied to language or could also depend on basic cognitive processes that affect all aspects of cognitive competence (domain-general processes). The present article examines this issue using a large battery of infant information-processing measures of memory, representational competence, processing speed, and attention, many of which have been shown to predict general cognition in a cohort of full-terms and preterms. Results showed that various aspects of infant memory and representational competence (a) related to language at both 12 and 36 months, (b) predicted similarly for the two groups, and (c) predicted 36-month language, independently of birth status, 12-month language, and the 12-month Bayley Mental Development Index. Additionally, the results established predictive validity for the MacArthur 12-month language measure. These findings support a domain-general view of language.     

Higher education provision using systems thinking approach – case studies

The purpose of this paper is to highlight the complexities involved in higher education provision and how systems thinking and socio-technical systems (STS) thinking approach can be used to understand the education ecosystem. Systems thinking perspective is provided using two case studies: the development of European Learner Mobility (EuroLM) service and the delivery of Enterprise System Management (ESM) course at the Birmingham City University, UK. The case studies present how systems thinking using STS approaches like applied organisational change and Cognitive Work Analysis can be used to capture a conceptual model of the education system for understanding the interactions and relationships between the people, technology, processes and the organisations. Using systems thinking perspective, EuroLM has developed a set of technical standards addressed to the European systems developers and ESM delivery ensures that students communicate and collaborate.     

Grades and college students' evaluations of their courses and teachers

From a review of existing research, it is concluded that college students' anticipated or actual grades in class are positively related to their evaluation of their courses and teachers. In general, the size of the association is small but not unimportant. A student's overall grade-point average appears to have little or no relationship to teacher or course evaluation, although limited evidence shows that a discrepancy between a student's grade-point average and his or her grade in a class is related to evaluations. Also, teacher- or course-induced interest in the subject is positively associated with evaluation, as are students' perceptions of the amount they have learned in a class and their performance on objective or standardized tests of achievement. Although it is thus possible that either these or other motivational and learning variables may account for the relationship between grades and evaluation, there is no evidence one way or the other that this indeed is the case. In all, currently available evidence cannot be taken as definitely establishing a bias in teacher evaluation due to the grades students receive or expect to receive in their courses, but neither is it presently possible to rule out such bias.This is the first paper of a projected series on teacher and course evaluation.     

The Implications of Culture and Identity: A Professor's Engagement with a Reform Collaborative

In this study, part of a larger United States project investigating K16 teachers and science reform, we seek to understand how a science professor's participation in a large-scale reform effort affects her conceptions of teaching, teachers, and reform. The topic in this study concerned how the professor's teaching identity was modified and created by the reform effort as she mediated her participation. A multiple-method approach utilizing (a) semi-structured interviews/correspondences with four students and the professor, (b) classroom observations, and (c) field notes, comprised the data collection. Results indicated that, although the professor was inclined to try out new teaching strategies in her classroom, the project failed to create pedagogical dissonance thus leading to her lack of desire to accommodate a more inquiry-based pedagogy.     

The significance of circumstances for college students' ratings of their teachers and courses

Although firm generalizations and conclusions cannot yet be drawn from the extant research on the effects on teacher and course ratings of the circumstances surrounding these evaluations, at least some studies have shown that college students' ratings of their teachers and courses are somewhat higher when students remain anonymous rather than identifying themselves, when the purported use of the ratings is an official or administrative one for use in salary, promotion, or tenure considerations rather than otherwise, and when the instructor is present rather than absent during the rating session. (The differences between each of these contrasted circumstances are usually rather small and do not inevitably appear across studies.) Certain variations in rating format have been found to make a difference in the ratings obtained, whereas other have not. From limited evidence, the exact timing (or occasion) of evaluation appears not to be important to ratings. Variability in sampling procedures, as it affects the composition of students available to complete rating forms, may or may not turn out to be a generally important element in ratings (as directly relevant data are collected). The analysis concludes with a discussion of (1) the presumed bias in ratings produced in certain of the rating conditions and (2) the more general issue of the comparability of ratings made in different circumstances of evaluation.     

Early Histories of School‐Aged Children With Attention‐Deficit/ Hyperactivity Disorder

In a prospective study of developmental outcomes in relation to early‐life otitis media, behavioral, cognitive, and language measures were administered to a large, diverse sample of children at 2, 3, 4, 6, and 9–11 years of age (N = 741). At 9–11 years of age, 9% of the children were categorized as having attention‐deficit/hyperactivity disorder (ADHD) based on parent report. Compared to the non‐ADHD group, the ADHD group had higher (i.e., less favorable) scores on parent and teacher versions of the Child Behavior Checklist at all ages. Children in the ADHD group also had lower scores on cognitive and receptive language measures in preschool. The findings support the concept that ADHD is a cognitive as well as a behavioral disorder.     

The effect of active versus passive exploration on memory for spatial location in children.

The effect of active exploration upon memory for spatial location of an event was assessed for children at 2 age levels. Each child took a walk through the same unfamiliar hallway in search of a hidden object which he was later asked to relocate. Half the children were accompanied by an adult holding their hand (passive condition), while the other half proceeded on their own with an adult following behind (active condition). An age x condition interaction revealed that active exploration significantly improved performance of the 3- and 4-year-old group while not affecting the performance of the 9- and 10-year-olds. The 3- and 4-year-olds in the active condition, however, were still significantly less accurate than the older children, despite their experience of self-directed exploration. The results are interpreted as supporting the hypothesis that self-directed activity serves to increase attention of preoperational children to relevant topological cues in the environment, whereas concrete operational children, due to their knowledge of projective and Euclidean space, demonstrate increased capacity to efficiently encode spatial information regardless of the mode of exploration.     

The association between student ratings of specific instructional dimensions and student achievement: Refining and extending the synthesis of data from multisection validity studies

This synthesis extends part of Peter Cohen's well-known examination of the association between student ratings of instruction and student achievement. The results of increasing the number of specific instructional dimensions considered and of preserving more of the information in the evaluations by multiple coding into these dimensions are compared with Cohen's findings. Extending the analysis further by changing the unit of analysis and the method of averaging correlations generally decreases the size of the associations. The instructor's preparation and organization, clarity and understandableness, stimulation of interest, motivation of students to reach high standards, encouragement of discussion and openness to others' opinions, and elocutionary skills consistently explain 10% or more of the variance in student achievement regardless of the method of averaging or the unit of analysis used. The size of the association between an instructional characteristic and student achievement, as one indicator of the characteristic's importance, is compared with three other indicators (extent to which students say the characteristic is important, extent to which faculty say it is important, and size of its correlation with the overall evaluation of the instructor).
