Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.

This study examines direct and indirect effects of family socioeconomic status (SES) and parental expectations on adolescents’ mathematics and problem-solving achievement in mainland China. SES here is composed of family wealth, home educational resources, and parental education. Over 5,000 ninth-grade students in 5 geographical districts of China participated in the study and were assessed by using the items adapted from the Programme for International Student Assessment (PISA). Results from structural equation modelling indicated that 2 components of SES – home educational resources and parental education – positively predicted parental expectations; however, the 3rd component – family wealth – negatively predicted parental expectations. Family wealth, parental education, and parental expectations significantly predicted mathematics achievement, and home educational resources, parental education, and parental expectations significantly predicted problem-solving achievement. The 3 components of SES also had significant indirect effects on both mathematics and problem-solving achievement through parental expectations, and the effect of family wealth was a suppression effect. These results were further discussed from Chinese cultural contexts. 相似文献

The present study examined the motivational correlates and achievement consequences of students’ help-seeking tendencies during sixth grade (N = 217). Students’ grades were collected from school records at the beginning and end of the school year. Midway through the year students reported on their academic self-efficacy and social demonstration goals; teachers reported on students’ help-seeking tendencies. First quarter grades and academic self-efficacy were positively related to adaptive help seeking and negatively related to avoidant help seeking. In addition, a social demonstration-approach goal was negatively related to adaptive help seeking. Help-seeking tendencies predicted 3rd quarter grades, controlling for 1st quarter grades. 相似文献

Principles of evolutionary educational psychology 总被引:1,自引:0,他引:1
Evolutionary educational psychology is the study of the relation between evolved systems of folk knowledge and inferential and attributional biases as these relate to academic learning in modern society. Following discussion and illustration of the mechanisms of natural selection and their application to human motivational, cognitive, and behavioral evolution, the basic premises and principles of evolutionary educational psychology are outlined. The gist is that the evolved cognitive systems and inferential biases that define folk knowledge are not sufficient for academic learning, but, at the same time, are the foundation from which academic competencies are built. A theoretical frame outlining the relation between folk knowledge and academic development is proposed and implications for motivational issues and instructional practices are detailed. 相似文献

We present PubSearch, a hybrid heuristic scheme for re-ranking academic papers retrieved from standard digital libraries such as the ACM Portal. The scheme is based on the hierarchical combination of a custom implementation of the term frequency heuristic, a time-depreciated citation score and a graph-theoretic computed score that relates the paper’s index terms with each other. We designed and developed a meta-search engine that submits user queries to standard digital repositories of academic publications and re-ranks the repository results using the hierarchical heuristic scheme. We evaluate our proposed re-ranking scheme via user feedback against the results of ACM Portal on a total of 58 different user queries specified from 15 different users. The results show that our proposed scheme significantly outperforms ACM Portal in terms of retrieval precision as measured by most common metrics in Information Retrieval including Normalized Discounted Cumulative Gain (NDCG), Expected Reciprocal Rank (ERR) as well as a newly introduced lexicographic rule (LEX) of ranking search results. In particular, PubSearch outperforms ACM Portal by more than 77% in terms of ERR, by more than 11% in terms of NDCG, and by more than 907.5% in terms of LEX. We also re-rank the top-10 results of a subset of the original 58 user queries produced by Google Scholar, Microsoft Academic Search, and ArnetMiner; the results show that PubSearch compares very well against these search engines as well. The proposed scheme can be easily plugged in any existing search engine for retrieval of academic publications. 相似文献

Breaking the Ivory Tower: Academic Entrepreneurship in the Life Sciences in UK and Germany 总被引:1,自引:0,他引:1
We examine engagement in commercial activities (consulting, patenting, and founding) among more than 2200 German and UK life scientists. We test hypotheses that include attributes of individuals, their material and social resources, and perceptions about values and reputation. We find that characteristics reflecting professional security, advantage and productivity are strong predictors for a greater breadth of participation in academic entrepreneurship, but not for all forms of technology transfer that we are able to test. For such academics, science and commerce go hand in hand, as they are best poised to straddle the boundary between industry and academy. We find strong support, however, that scientists perceive the value of patenting differently, and the level of reputational importance placed on scientific compared to commercial achievements matters in shaping commercial involvement. 相似文献
