Recommender system for learning SQL using hints     

Dejan Lavbič  Tadej Matek  Aljaž Zrnec 《Interactive Learning Environments》2017,25(8):1048-1064

Today’s software industry requires individuals who are proficient in as many programming languages as possible. Structured query language (SQL), as an adopted standard, is no exception, as it is the most widely used query language to retrieve and manipulate data. However, the process of learning SQL turns out to be challenging. The need for a computer-aided solution to help users learn SQL and improve their proficiency is vital. In this study, we present a new approach to help users conceptualize basic building blocks of the language faster and more efficiently. The adaptive design of the proposed approach aids users in learning SQL by supporting their own path to the solution and employing successful previous attempts, while not enforcing the ideal solution provided by the instructor. Furthermore, we perform an empirical evaluation with 93 participants and demonstrate that the employment of hints is successful, being especially beneficial for users with lower prior knowledge.  相似文献   

How to Analyze Interpersonal and Individual Effects in Peer-Tutored Reading Intervention     

Bettina Müller  Tobias Richter  Ana Križan  Teresa Hecht  Marco Ennemoser 《Journal of Experimental Education》2016,84(4):744-763

Reading strategy interventions relying upon peer tutoring are a common way to foster poor readers' comprehension skills. Those interventions are based on the assumption that tutees benefit from the (higher) reading skills of their tutors. However, this interpersonal effect has not yet been tested explicitly because the effectiveness of peer tutoring is commonly analyzed separately for tutees and tutors or with aggregated data. The present study illustrates how interpersonal and individual effects of a peer-tutored reading strategy intervention can be estimated using dyads as units of analysis in structural equation modeling. To demonstrate the application of the model, data from an experimental intervention study comparing the effects of a peer-tutored reading strategy training and a control condition in Grade 4 (N = 68 dyads) were analyzed.  相似文献

The challenges of setting up the evaluation of extension systems by using a systems approach: the case of Greece,Italy and Slovenia     

Evagelos D. Lioutas  Chrysanthi Charatsari  Majda Černič Istenič  Giuseppe La Rocca  Marcello De Rosa 《The Journal of Agricultural Education and Extension》2019,25(2):139-160

Purpose: Considering current debates on ecosystem services’ effectiveness and the AIS/AKIS functioning, in this study we suggest a new, systemic way to evaluate extension systems (ESs). Using this model, we compared the effectiveness of ESs in three countries with essential differences but also characteristic similarities in their agricultural sectors: Greece, Italy and Slovenia.

Design/methodology/approach: Initially, we defined ‘extension system’ as a wide range of actors integrating resources with the aim of co-producing value (not for but with) farmers. To capture the value flow within this constellation of actors we distinguished between the notion of ‘value in production’ – i.e. the value embodied in service offerings – and the value emanating when service content is used in real settings or ‘value in use.’

Findings: Our approach revealed that, despite their structural and organizational differences, the ES in the three countries share common problems arising from a limited focus on the issue of value in use.

Practical implications: The application of a systemic approach – seeing farmers as co-creators and not as end-users of extension services – in the evaluation of ESs contributes to better understand the complexity of value flow within the system and can strengthen extension systems’ effectiveness.

Theoretical implications: The present study, by reconsidering traditional evaluation approaches and by focusing on value co-production, offers an alternative value-centric framework for the conceptualization of extension services and points out to the need for refining the evaluation criteria of ESs.

Originality/value: Our work, by emphasizing the reciprocal creation of value within ESs, and by adding the concept of value in use, offers a new systems approach worth considering when evaluating ESs within different organizational and sociocultural contexts.  相似文献   

Teachers’ perceptions of the inclusion of marginalised groups   总被引：1，自引：0，他引：1  

Mojca Peček  Ivan Čuk  Irena Lesar 《Educational studies》2008,34(3):225-239

This paper is based on the concept of inclusion as a process of recognising and minimising the barriers to learning and participation of all children, with teachers as the key players in implementing inclusion in practice. There are two key questions: (1) How do teachers rank different groups of marginalised children? (2) How do teachers see their own role, the role of the marginalised and other children, and their parents in the inclusion process? The groups included in the research were children with special needs, migrants from former Yugoslavia, Roma/Gypsies and children from poor families. In the latter group, it also looked at their counterparts, the children of wealthy parents. Research carried out on a representative sample of primary school teachers in Slovenia showed that children with special needs are among all surveyed groups of children those seen as the most helpless. For these children, teachers are also most likely to lower learning and discipline standards, while at the same time feeling the least qualified to teach them and seeing them also as having the lowest abilities. In the teachers’ opinion, parents of other children have the greatest reservations when their child associates with a Roma/Gypsy child, and teachers also put the least trust in Roma/Gypsy parents.  相似文献   

The effect of potential fall distance on hormonal response in rock climbing     

Jiří Baláš  David Giles  Leona Chrastinová  Kateřina Kárníková  Jan Kodejška  Alžběta Hlaváčková 《Journal of sports sciences》2017,35(10):989-994

The aim of this study was to examine the effect of alterations in potential lead fall distance on the hormonal responses of rock climbers. Nine advanced female climbers completed two routes while clipping all (PRO-all) or half (PRO-½) of the fixed points of protection. Venous blood samples were analysed for total catecholamines, noradrenaline (norepinephrine), adrenaline (epinephrine), dopamine, lactate, cortisol and serotonin. Differences between the two conditions pre, immediately post and 15 min post climbing were assessed using a 2 × 3 repeated measures ANOVA. All hormones and blood lactate concentrations increased significantly (P < 0.05) immediately post climb, except for cortisol. Peak cortisol concentrations did not occur until 15 min post ascent. Further, significant interactions between climbing and clipping conditions were found for total catecholamines (890% of basal concentration in PRO-½ vs. 568% in PRO-all), noradrenaline (794% vs. 532%) and dopamine (500% vs. 210%). There were no significant interactions for adrenaline (1920% vs. 1045%), serotonin (150% vs. 127%) or lactate (329% vs. 279%). The study showed a greater catecholamine response with an increase in potential lead fall distance. The most pronounced increases seen in catecholamine concentration were reported for dopamine and noradrenaline.  相似文献

Who is responsible for vulnerable pupils? The attitudes of teacher candidates in Serbia and Slovenia     

Mojca Peček  Sunčica Macura-Milovanović 《欧洲师范教育杂志》2012,35(3):327-346

In the ongoing trend towards inclusive education, initial teacher education programmes must ensure that prospective teachers are prepared to teach all pupils effectively. The study presented in this paper aimed to explore the attitudes of teacher candidates in Serbia and Slovenia towards responsibility for the teaching and learning of vulnerable pupils in mainstream elementary schools. Using a quantitative approach, the study sought to elicit teacher candidates’ views about division of responsibility for the academic achievement and additional support of vulnerable pupils and their views on the factors that most affect learning difficulties in those pupils. Our findings indicate that teacher candidates’ feelings of responsibility are unlikely to help when instructing vulnerable pupils. The implications of these findings are discussed and we suggest several ways to improve teacher education programmes to promote inclusive education based on the concept of quality education for all.  相似文献
