Research has found mixed evidence for the production effect in childhood. Some studies have found a positive effect of production on word recognition and recall, while others have found the reverse. This paper takes a developmental approach to investigate the production effect. Children aged 2–6 years (n = 150) from a predominantly white population in Ottawa, Canada were trained on familiar words which were either seen, heard or produced, followed by a recall task. Results showed a developmental shift: younger participants showed a reverse production effect, recalling more words that were heard during training, while older children showed the typical production effect, recalling more produced words. The effect of production on recall is not unidirectional and varies by age.  相似文献

The underlying structure of the Revised Two factor version of the Study Process Questionnaire (R-SPQ-2F), a 20-item instrument for the evaluation of students’ approaches to learning (SAL), was examined at item level using two independent groups of undergraduate students enrolled in the first (n=314) and last (n=522) years of their studies. The methods used were (a) Exploratory factor analysis (EFA) assisted by rigorous procedures such as Velicer’s MAP test, parallel analysis and the Schmid Leiman solution with the first sample; and (b) confirmatory factor analysis (CFA) with the second sample. The results of EFA indicated that the latent structure of the R-SPQ-2F is best described by two factors and the results of CFA suggested that out of four a priori structural models, the best fit was achieved by a simple first-order two-factor model. Taken together, these results seemed to converge, suggesting (a) that SAL might be defined as a co-variation between a motive and its intended strategy, these not necessarily being divided into separate first-order factors (subscales), and (b) that the underlying structure of the R-SPQ-2F is apparently non-hierarchical, being best described by a parsimonious first-order two-factor model in which Deep and Surface learning approaches are each measured by their ten corresponding items.  相似文献

The purpose of this study was to develop a teaching quality assessment questionnaire and assess its reliability by using it with a sample of first‐year medical students. Principal components analysis with varimax orthogonal rotation resulted in the development of a 12‐item, two‐component tool, adequate for use in lectures and small‐group sessions. The two components were named ‘curriculum’ and ‘relationship’. The Cronbach coefficient alpha values indicated high reliability and internal consistency. According to the results obtained this teaching quality scale is a reliable measure and may be useful in identifying themes in disciplines and among teachers that may benefit from some professional development. Amongst its advantages is that it can be used with an optical reading tool.  相似文献

The research literature on the topic of “spatial ability” reveals that it has a major influence on achievement in the fields of science, technology, engineering and mathematics. Additionally, previous studies indicate the existence of a gender gap in spatial ability in favour of males. Mental rotation, one subskill of spatial ability, is an area in which gender differences are greater. At the same time, educational robotics is seen as one of the more promising technologies in educational contexts for the future. We conducted a quasi-experimental study with 142 seven- and eight-year-old students aimed at analysing whether robotics-based instruction may produce greater learning gains on mental rotation abilities compared to traditional instruction. The intervention was developed in the context of map-reading tasks, which are part of the curricular content in Mathematics and Social Sciences at this age. The results showed that for males, the robotics-based instruction promoted a significantly greater improvement in students’ mental rotation abilities compared to the control group. By contrast, no significant differences were observed for females. Although this study provides empirical evidence of the potential of robotics-based instruction, future studies need to deeply analyse the existence of gender differences in the learning gains obtained through educational robotics.  相似文献

This study created a Spanish triangulated version of the European Bullying Intervention Project Questionnaire and obtained indicators of its validity and reliability. This new tool allows researchers to triangulate and flexibly investigate the three main roles in school bullying, obtaining seven potential roles (pure victim, pure bully, pure bystander, bully/victim, victim/bystander, bully/bystander, and bully/victim/bystander). The sample was 2,068 adolescents and young adults aged 11–19 years (Mage = 14.2 ± 1.48 years old; 53.8% females). Confirmatory factor analysis indicated a good fit for the three-related-factor model and adequate reliability (ω > 0.91) in all dimensions. About 28.2% of the sample reported victimization; of whom only 2.9% were pure victims, 15.1% were victim/bystanders, and 9.8% were involved in all three roles (bully/victim/bystanders). Only 0.8% played the role of a pure bully, and 0.4% were bully/victims. The most prevalent profile was that of pure bystander (30%). These results are discussed in light of their importance for the interpretation of the prevalence of traditional bullying, and their implications for bullying assessments and interventions.  相似文献
