Configural conditioning in the CER: A possible artifact

Gray and Lethbridge (1976) have reported a demonstration of configural conditioning in the CER in rats. With repeated reinforcement of a compound CS, suppression to the elements diminished considerably, while suppression to the compound remained substantially intact. The basic form of the Gray and Lethbridge findings has been replicated in the present study. We observed, however, that suppression to the compound itself diminished with repeated reinforcement of the compound. Further, we also tested the compound after deliberate extinction of the elements. This test of the excitatory effect of the “configurai cue” indicated that it also had diminished with repeated reinforcement of the compound. The observed greater suppression to the compound than to the elements can be parsimoniously interpreted as a simple summation effect, and the attenuation of suppression with repeated reinforcement is common in CER studies. Thus, the data require no appeal to configural conditioning.     

Personality and Performance Research—New Theories and Directions Required

One purpose of teacher education is to help future teachers develop the necessary knowledge, abilities, and skill for good teaching. A second purpose is to develop the commitment to use this knowledge, ability, and skill when trainees graduate from the training program and begin their teaching careers. There is evidence to suggest that teacher education programs can successfully achieve the first purpose, but success in the development of commitment to good teaching has not yet been demonstrated. By applying Becker's conception of commitment, a two-step plan for developing commitment in teacher education is proposed. The first step is to identify and assess commitment, the second step is to record behavioral indicators of commitment and to use these records to help future teachers develop commitment. In physical education, the improvement of teaching is vital to the future of the field; thus it is critical that teacher education programs help their students develop commitment to good teaching as well as develop effective teaching skills     

Exploring the effects of multimedia learning on pre-service teachers’ perceived and actual learning performance: the use of embedded summarized texts in educational media

In light of the increased usage of instructional media for teaching and learning, the design of these media as aids to convey the content for learning can be crucial for effective learning outcomes. In this vein, the literature has given attention to how concurrent on-screen text can be designed using these media to enhance learning performance. The present study sought to examine whether utilizing concurrent on-screen summarized text (CST) could improve students’ learning performance while estimating their perception of performance when learning with educational multimedia content. Although the findings did not show a significant improvement in students’ performance on the retention test among the CST groups, students exhibited a considerable higher level of confidence toward their performance. The findings suggest that students who learned with CST educational media may have overestimated their performance. Further analysis and discussion are included.     

Enhancing Social Work Practice with Older Adults: The Role of Infusing Gerontology Content into the Master of Social Work Foundation Curriculum

Based on a geriatric enrichment (GeroRich) effort, this study examines outcomes of infusing aging content across the master of social work (MSW) foundation curriculum. In a longitudinal research design tracking one class, there were no significant changes observed in students' levels of experience and interest in gerontological social work. Significant increases were observed in self-rated levels of gerontological knowledge and practice skills—clinical and macro. Full-time status, less gerontological experience, and higher knowledge predicted greater practice skills at the follow-up. Implications for educating the next generation of social workers to better meet the needs of older adults and their families are discussed.     

An Investigation of the Language Demands in Content Assessments for English Language Learners

The purpose of the present study is to examine the language characteristics of a few states' large-scale assessments of mathematics and science and investigate whether the language demands of the items are associated with the degree of differential item functioning (DIF) for English language learner (ELL) students. A total of 542 items from 11 assessments at Grades 4, 5, 7, and 8 from three states were rated for the linguistic complexity based on a developed linguistic coding scheme. The linguistic ratings were compared to each item's DIF statistics. The results yielded a stronger association between the linguistic rating and DIF statistics for ELL students in the “relatively easy” items than in the “not easy” items. Particularly, general academic vocabulary and the amount of language in an item were found to have the strongest association with the degrees of DIF, particularly for ELL students with low English language proficiency. Furthermore, the items were grouped into four bundles to closely look at the relationship between the varying degrees of language demands and ELL students' performance. Differential bundling functioning (DBF) results indicated that the exhibited DBF was more substantial as the language demands increased. By disentangling linguistic difficulty from content difficulty, the results of the study provide strong evidence of the impact of linguistic complexity on ELL students' performance on tests. The study discusses the implications for the validation of the tests and instructions for ELL students.

Opportunities to Learn and Achievement in Mathematics in a Sample of Sixth Grade Students in Lima, Peru

In recent years, the mathematics achievement of Peruvian students has been evaluated in three national and two international studies. The results in all cases suggest very poor learning. A similar situation is found in many developing countries. In this study, we analyzed the opportunities to learn (OTL) mathematics of sixth grade students from 22 public schools in Lima, Peru. OTL were defined in this study as curriculum coverage, cognitive demand of the tasks posed to the students, percent of mathematical exercises that were correct and quality of feedback. These variables were coded in the workbooks and notebooks of the students, which were gathered at the end of the school year (at the same time, the mathematics achievement test was administered). The results show that: (a) regarding OTL, less than half of the exercises available in the workbooks were solved, teachers overemphasize some topics of the national curriculum ({i.e.} related to Number and Number Sense), they pose tasks that are at very low levels of cognitive demand, and it is common to find mistakes in the students' answers to problems that have no feedback (or even worse, the feedback is wrong); (b) students in relatively poorer, multigrade classrooms have less OTL; (c) OTL, as defined earlier, is positively associated with achievement.A preliminary version of this paper received the Research Medal in the category Knowledge, Education andTechnology at the Annual Meeting of the Global Development Network (GDN) in Cairo, in January 2003.
