Some strategies to improve performance in school chemistry,based on two cognitive factors

The background to this study are the difficulties facing the majority of Greek pupils in understanding chemistry concepts and, therefore, performing well in the National Examinations. The aim was to explore the problems and to suggest ways in which the situation might be improved. Working with 105 Greek pupils aged 15 to 16, the first stage of the enquiry confirmed that both working memory space and extent of field dependency were two psychological factors affecting performance. This is at least part of the nature of the problem. In the second stage, an attempt was made to explore how the problems might be reduced. New teaching materials were constructed to minimize any limitations to learning caused by working memory space and problems associated with being field dependent. The use of the new materials was compared to the normal teaching process working with 210 Greek pupils aged 15 to16. It was found that there was a significant difference in the average improvement of the experimental group and the control group, in favour of the experimental group. This result was independent of the effect of the teacher, and of the interaction of teaching method and teacher. It is suggested that approaches to learning must take into account cognitive factors in the learners in the context of information processing understandings of learning. If this is done, learning is much more effective.     

Understanding research strategies to improve ERA performance in Australian universities: circumventing secrecy to achieve success

ABSTRACT

Many Australian universities have prioritised improving discipline performance on the national research assessment – Excellence for Research in Australia. However, a culture of secrecy pervades Excellence in Research for Australia (ERA). There are no specified criteria for the assignment of ratings on a 5-point scale ranging from ‘well above world standard’ (5) to ‘well below world standard’ (1). No rationale is provided to institutions for their discipline ratings and university staff on the ERA panels sign confidentiality agreements. However, what is available to universities are the research strategies that each university documents to improve its ERA performance in its Mission-based Compact, a government funding agreement. Thus, the purpose of this paper is to investigate the similarities and differences in the research strategies that universities with different performance profiles employ. Following an analysis of the strategies, substantial commonality was identified in strategy use. However, what was different was how universities employed these strategies and the associated contexts.     

对认知策略的几点认识

认知策略是学习策略的核心部分,也是掌握学习策略的关键。认知策略是学习信息加工的方法和技术,主要包括集中注意策略、获取与编码策略、储存和组织策略、再认和回忆四部分内容。在课堂教学中,教师要充分运用认知策略向学习传授知识信息,并使学生掌握认知策略的方法,提高学生学习的效率和兴趣。     

Motivational and cognitive test-taking strategies and their influence on test performance in mathematics

A structural equation model of relationships among testing-related motivation variables (test value, effort, self-efficacy, and test anxiety), test-taking strategies (test tactics and metacognitive strategies), gender, and math test performance were examined with a sample of 10th graders (N = 438; 182 males and 256 females). In general, motivation variables influenced the use of test-taking strategies and demonstrated stronger impacts on math performance than did test-taking strategies. Gender differences were found in self-efficacy and test anxiety. With a few surprising but culturally relevant results that warrant further investigation, the current study extended previous works on antecedents of academic achievement to testing situations within the self-regulated learning theory.

Using bidirectional links to improve peer-to-peer lookup performance

INTRODUCTION Peer-to-peer computing has become a populardistributed computing paradigm. Efficient resourcelookup is essential for such systems. As we know, most of the deployed peer-to-peersystems are unstructured. Napster is based on a cen-tral directory and was in popular use during early daysSoon after, Gnutella and KaZaA were deployedwidely. However, all these popular unstructuredpeer-to-peer systems suffer from unscalability. Fortunately, there are new kinds of peer-to-peernetwor…     

An intervention to improve school and student performance

Georgia Leadership Institute for School Improvement (GLISI) used ISPI's 10 Standards of Performance Technology to share the design, development, and implementation of an intervention striving to help Georgia districts and schools share their success stories in a clear and concise format. This intervention took the form of a PowerPoint presentation, GLISI Promising Practices, and has become a successful tool for districts to share and communicate their success.     

Using screen capture feedback to improve academic performance

Feedback is an effective instructional practice for improving achievement. The importance of feedback has been understood by teachers for many years, yet recent research has elevated its status. One characteristic of effective feedback is personalized comments, which assist students in understanding their performance. Most research analyzes the effects of written feedback. Some current studies have examined the effects of alternative delivery methods, such as audio. One new approach for creating and delivering feedback is through screen capture technology. A case study was conducted to examine the effects of this method on the academic performance of 36 undergraduate students in a teacher education course. Results showed that screen capture feedback is effective for guiding corrections on a writing assignment. Students also reported that feedback was useful for knowing what they were doing right or wrong and that they would prefer more feedback of this type.
