A synthesis of research on effectiveness of school-based drug prevention programmes / Claves de eficacia de los programas de prevención de consumo de sustancias en el contexto escolar: una meta-revisión

Abstract

Relevant information on effectiveness of school-based drug prevention programmes is available. Despite this, there is still contradictory evidence that makes it necessary to continue to shed light on this issue. Based on a synthesis research method, the aim of this study was to determine the relevant variables that enhance the efficacy of these programmes and to determine the weight of their empirical evidence. Furthermore, several features of the evaluation designs whose variables had been proven effective were examined. A systematic review of periodical literature was conducted, which led us to extract 1,622 papers, of which 17 studies were analysed. An in-depth analysis of these publications led us to identify 29 key variables associated with the efficacy of the programme, which were ranked according to the weight of their empirical evidence. Moreover, the characteristics of the studies included in the review highlighted the need to improve the rigorousness and quality of the evaluation designs in this field.     

Revaluing the enlightenment: reason and imagination

In higher education teaching, enhancing learner autonomy has become a key concern for curriculum planners and classroom teachers. The significant body of research about learner autonomy in language learning over the last 20 years (e.g. Holec 1981, 1988; Riley 1985; Dickinson 1987, 1992; Wenden & Rubin 1987; Little, 1991; Dam, 1995; Benson & Voller, 1997) has indicated an on-going search for more understanding of how learner autonomy can be implemented in different contexts. This paper is based on a research study which was conducted in the Hong Kong Polytechnic University in Hong Kong. The study explores learners' attitudes and expectations of language learning, teacher and learner roles, their learning preferences and perceptions of learner autonomy. The paper reports the results and discusses their implication on the development of a learner-centred approach in higher education.     

Single comments or average ratings: which elements of RateMyProfessors.com™ shape university students’ judgments and course choice intentions?

The use and abuse of course and lecturer rating websites such as RateMyProfessors.com? is a highly relevant topic for universities’ evaluation and assessment policies and practice. However, only a few studies have paid attention to the actual influence of teaching evaluation websites on the students themselves—that is, their perceptions of a certain course and their course choice intention at university. Findings point to the fact that positive comments on the website about professors improve students’ evaluations. However, professor evaluation websites contain two types of information: single student comments and average ratings. Research on exemplification effects has shown that single cases often have a stronger influence on recipients than more valid base rate information. We test this assumption in an experiment (n?=?126) using a professor evaluation website stimulus. Results show that single comments strongly influence opinions and course choice intentions but that they are moderated by the valence of the average rating.     

Catalog Users “In the Wild”: The Potential of an Ethnographic Approach to Studies of Library Catalogs and Their Users

An increasing number of library user studies are employing ethnographic techniques as an alternative to more traditional qualitative methods such as surveys. Such techniques, however, are only beginning to see significant application to catalog user studies. Beginning with a discussion of the applied ethnographic method and its current usage within the field of Library and Information Science research, this article will assess methods that have traditionally been applied to studies of catalog users and present the case for the potential of an ethnographic approach for future catalog evaluation and design.     

The effects of features of examination questions on the performance of students with dyslexia

This research investigated whether features of examination questions influence students with dyslexia differently to others, potentially affecting whether they have a fair opportunity to show their knowledge, understanding and skills. A number of science examination questions were chosen. For some questions two slightly different versions were created. A total of 54 students considered by their teachers to have dyslexia and a matched control group of 51 students took the test under exam conditions. A dyslexia screening assessment was administered where possible and some students were interviewed. Facility values and Rasch analysis were used to compare performance between the versions of the same question and between those with and without dyslexia. Chi‐square statistics found no statistically significant differences in performance between groups or between question versions. However, some tentative implications for good practice can be inferred (e.g. avoiding ambiguous pronouns, using bullet points).     

Self-controlled learning benefits: exploring contributions of self-efficacy and intrinsic motivation via path analysis

Research has shown learning advantages for self-controlled practice contexts relative to yoked (i.e., experimenter-imposed) contexts; yet, explanations for this phenomenon remain relatively untested. We examined, via path analysis, whether self-efficacy and intrinsic motivation are important constructs for explaining self-controlled learning benefits. The path model was created using theory-based and empirically supported relationships to examine causal links between these psychological constructs and physical performance. We hypothesised that self-efficacy and intrinsic motivation would have greater predictive power for learning under self-controlled compared to yoked conditions. Participants learned double-mini trampoline progressions, and measures of physical performance, self-efficacy and intrinsic motivation were collected over two practice days and a delayed retention day. The self-controlled group (M = 2.04, SD = .98) completed significantly more skill progressions in retention than their yoked counterparts (M = 1.3, SD = .65). The path model displayed adequate fit, and similar significant path coefficients were found for both groups wherein each variable was predominantly predicted by its preceding time point (e.g., self-efficacy time 1 predicts self-efficacy time 2). Interestingly, the model was not moderated by group; thus, failing to support the hypothesis that self-efficacy and intrinsic motivation have greater predictive power for learning under self-controlled relative to yoked conditions.     

Towards National Security and Peace: The Strategic Role of Libraries

This article is aimed at examining the causes of insecurity and violence in Nigeria and around the world. It discusses the active roles libraries play in promoting peace and security in different countries. It highlights the fact that several threats to lives, ranging from terrorism, communal and tribal clashes, kidnapping, pollution, health, physical and environmental hazards, and economic crisis among others, can be curbed through information and intelligence services. Premised on these, this article seeks to analyze and make recommendations for the promotion of literacy by libraries, build collaborative relationships between librarians and security operatives, and provide suggestions for the provision of current information against terrorism and security of lives and properties. It also seeks to provide current news on terrorism and intelligence services in Nigeria and around the world, and on social and national security for peaceful co-existence in communities.     

PUPILS’ ATTITUDES TOWARDS ART TEACHING IN PRIMARY SCHOOL: AN EVALUATION TOOL

Pupils’ attitudes influence both learning and teaching processes and affect the way pupils will engage with art as adults. This article introduces an attitude scale, the Attitude Scale for Art Experienced in School (ASAES), which comprises four subscales: enjoyment, confidence, usefulness, and support. A three-step procedure was followed for the construction and validation of the scale which was administered to 420 primary school pupils in Cyprus. The scale's psychometric properties are evaluated through Confirmatory Factor analysis. The findings indicate that teachers’ art specialisation and attitudes towards art teaching, pupils’ perceived competence and pupils’ gender are three important variables that influence the formation of pupils’ attitudes. Important interactions between these variables are also reported.     

Phantoms and fabrications:young children's detection of implausible lies

The present study investigated whether young children are gullible and readily deceived by another's lies. Specifically, this study examined whether young children believe a lie teller's statement when the statement violates their developing knowledge of a distinction between reality and fantasy. In the first three experiments 3- to 6-year-olds (N = 293) were presented with either a story or a live staged event in which an individual made an implausible statement about a misdeed (claiming that a ghost jumped out of a book and broke a glass). A significant age effect was obtained: 5- and 6-year-olds tended to report that the individual who made the implausible statement had actually committed the misdeed, whereas 3- and 4-year-olds tended to accept the claim of the protagonist. Experiment 4 revealed that 5- and 6-year-olds (N = 43) not only disbelieved an individual's implausible statement but also inferred that the individual was lying and had a deceptive intent. In contrast, Experiment 5 revealed that 3- and 4-year-olds (N = 41) had difficulty disbelieving an individual's implausible claim about an inanimate object (i.e., the claim that a chair came alive and broke the glass). The findings suggest that 5- and 6-year-olds are not so gullible as previously thought, and that they use their well-developed real-world knowledge to detect scapegoating lies. In contrast, many younger children tend to believe another's implausible lies, perhaps due to the fact that the knowledge needed to detect such lies has not yet been consolidated.
