Early Mathematical Growth: How to Support Young Children’s Mathematical Development

The purpose of this critical analysis was to investigate the young children’s sense of numerical magnitudes and the important attributes of classrooms where children in kindergarten and first grade are exposed to mathematics. This study aimed to offer guidelines that will assist teachers as they teach mathematics to children between the ages of five and seven.     

Proactive interference by cues presented without outcomes: Differences in context specificity of latent inhibition and conditioned inhibition

This report is part of a larger project examining associative interference as a function of the nature of the interfering and target associations. Lick suppression experiments with rats assessed the effects of context shifts on proactive outcome interference by latent inhibition (LI) and Pavlovian conditioned inhibition (CI) treatments on subsequently trained Pavlovian conditioned excitation treatment. LI and CI were trained in Context A during Phase 1, and then excitation treatment was administered in Context B during Phase 2, followed by tests for conditioned excitation in Contexts A, B, or C. Experiment 1 preliminarily established our LI and CI treatments and resulted in equally retarded acquisition of behavioral control when the target cue was subsequently trained as a conditioned excitor and tested in Context A. However, only CI treatment caused the target to pass a summation test for inhibition. Centrally, Experiment 2 consisted of LI and CI treatments in Context A followed by excitatory training in Context B. Testing found low excitatory control by both LI and CI cues in Context A relative to strong excitatory control in Context B, but CI treatment transferred to Context C more strongly than LI treatment. Experiment 3 determined that LI treatment failed to transfer to Context C even when the number of LI trials was greatly increased. Thus, first-learned LI appears to be relatively context specific, whereas first-learned CI generalizes to a neutral context. These observations add to existing evidence that LI and CI treatments result in different types of learning that diverge sharply in transfer to a novel test context.     

Is students’ energy literacy related to their university’s position in a sustainability ranking?

Abstract

University rankings are increasingly important internationally, and in the UK include a sustainability ‘Green League’. However, there is little evidence about experiences of studying in ‘sustainable universities’. We report an empirical study at five universities in varied positions in the Green League, exploring students’ energy literacy, environmental attitudes and perceptions of their institution’s energy-saving efforts. Although the link to energy literacy is not clear, findings suggest that there are significant differences between students’ environmental attitudes at universities placed at different points in the league. In addition, students at higher ranked universities are more positive about their university’s energy-saving efforts, suggesting that these institutions may exhibit more overt manifestations of sustainability. This is important since students report being more likely to choose energy-conservation behaviours if there is visible representation of energy use. The study is the first to attempt a comparison between universities at different positions in a sustainability ranking.     

Preschool children's math-related behaviors mediate curriculum effects on math achievement gains

This study used a mediational model to examine the effect of curriculum condition on student behaviors and how those behaviors related to math achievement gains. The student behaviors examined were children's participation in learning-related activities, talking during learning activities, and level of engagement with the materials. Conducted as part of a larger project involving the implementation and evaluation of a preschool mathematics curriculum, this study involved twenty urban prekindergarten sites with 57 classrooms randomly assigned to the new curriculum or a practice-as-usual condition. The final analytic sample included 675 children, predominately from low-income homes. Results showed that the greater gains made by children in curriculum classrooms were mediated by the number of times children were observed focused on mathematics and the number of times they were observed talking during mathematics. Findings from this study demonstrate the importance of focusing on children's actual responses to a new curriculum in determining its effects.     

THE DEPARTMENT CHAIR AS SPEAKER OF THE HOUSE: SHARED AUTHORITY IN THE COMMUNITY COLLEGE DEPARTMENT

The department chair position is vital to the effective administration of both the academic unit and the entire college. Inherent in the roles and tasks of the individual position is a responsibility for consensus development, which in turn requires the involvement of faculty in decision-making activities. This consensual development dictates that faculty who are specialists in their particular academic disciplines be involved in decisions ranging from admissions and grading to institutional policy formation and cross-disciplinary curricula development. The current study was conducted to examine the perceptions of department chairs in the involvement of faculty in departmental decision-making.     

Using micros for test development

Conclusion Which is the better choice: general item bank software or a word processor program? Your answer is dependent upon your computer skills, the amount of test development work you do, and the nature of investment your school is willing to make for software. Both have their relative strengths and weaknesses. The trade-offs between the two approaches are real, important, and in time will probably favor the item bank software. At the moment, however, we recommend a good word processing program for most teachers. What can you expect the future to bring? At a minimum, test preparation options will continue to expand and improve. We suggested earlier that the technology is changing rapidly. For example even now you can place a printed copy of test items into an optical character recognition (OCR) scanner (similar to a photocopy machine) and read the items into a digital form which either a word processor or a test generator can use. Instead of having to type your collection of test items before selecting, editing, and printing them, the computer will read them from the paper. This new scanning technology, unfortunately, requires expensive software, powerful microcomputers, and the scanner itself costs over $1000. In addition, the accuracy of the character recognition is not perfect—especially with less than the ideal printed copy from which to work. It will be years before most of us have ready access to this technology. Even better options will be available, however, don’t wait for the next major breakthrough. There will always be another breakthrough on the horizon. You can start improving your test development process now     

Topicalization and the Processing of Expository Prose by Children: mediating effects of cognitive styles and content familiarity

This study assessed the effects of text topicalization conditions (initial position, final position, or no topic sentence) on the comprehension of main ideas and specific passage information for middle school readers. Also of interest were interactions of topic familiarity and readers’ cognitive styles (degree of field independence) with text topicalization. One hundred and seven subjects were randomly assigned to one of the three topicalization conditions and read three familiar and three less‐familiar multipleparagraph expository texts. Main idea comprehension was assessed with both a sentencesummary (generation) and best‐title (recognition) task. Comprehension of specific passage information was evaluated with multiple‐choice items. Text topicalization effects were observed for main idea comprehension (with initial position best, followed by final position), while topic familiarity resulted in higher comprehension scores for specific passage information. Moreover, a cognitive style‐text topicalization interaction was found on the best‐title task; in this case, relatively field dependent readers were assisted by a final topic sentence placement. Implications are drawn for future research concerning the complex interplay of texts, tasks and readers in prose‐processing.     

Analyzing a service-learning experience using a social justice lens

This mixed methods study explores a service-learning experience embedded in a social foundations course in a teacher education program. The authors differentiate learning outcomes for social justice and charity service-learning, and utilize this framework to examine whether the service-learning experience fosters a social justice perspective. The findings demonstrate that while the experience did foster social justice perspectives for some students, the data also reflect evidence of learning outcomes that align with charity service-learning.
