Response times (RTs) have recently attracted a significant amount of attention in the literature as they may provide meaningful information about item preknowledge. In this study, a new model, the Deterministic Gated Lognormal Response Time (DG-LNRT) model, is proposed to identify examinees with item preknowledge using RTs. The proposed model was applied to two different data sets and performance was assessed with false-positive rates, true-positive rates, and precision. The results were compared with another recently proposed Z-statistic. Follow-up simulation studies were also conducted to examine model performance in settings similar to the real data sets. The results indicate that the proposed model is viable and can help detect item preknowledge under certain conditions. However, its performance is highly dependent on the correct specification of the compromised items. 相似文献

What makes some human faces more attractive than others is an interesting phenomenon which is difficult to explain based on few facial features. Research indicated that many facial parameters contribute to generation of a “harmonious face” which is found appealing by most observers. There are different theories developed on which and how these parameters blend in to make a harmonious face. Determination of these parameters and the underlying mechanism is important since achieving a harmonious face is the primary goal in dental and aesthetic surgical procedures. This article presents a model developed for computer-aided assessment of facial harmony, which assesses the facial harmony of male patients and generates a score that reflect the level of harmony. The computer-aided tool presented in this paper uses “theory of averages” as a mechanism for measurement of facial harmony which is frequently used by aesthetic surgeons and orthodontists for assessment of facial proportions of the patient. The output of the developed model is an index which reflects the degree of harmony of facial features and how well they blend into each other. 相似文献

This study aims at exploring how linguistic proficiency, target culture experience, and formal education are related to the learning of intercultural communicative competence (ICC). It presents the theoretical underpinnings of ICC in the light of recent literature. Then, it continues with the methodology section that includes a quantitative research study in which 35 students at the Department of English Language Teaching (ELT) at European University of Lefke (EUL) participated. The participants of the study had different linguistic proficiencies ranging from waystage or elementary level (A2) to vantage or upper intermediate level (B2). The paper concludes by stating the findings of the research and also by making some recommendations for language teachers to better develop the learners’ ICC in teaching English as a second language (TESL)/teaching English as a foreign language (TEFL) contexts. 相似文献

This study attempted to explore Turkish headteachers’ and teachers’ burnout and job satisfaction relating to work status, gender and years work-experiences. The purpose of this study is to find out whether there is difference between headteachers’ and teachers’ burnout and job satisfaction in terms of work status, gender and years work-experiences. In this study, quantitative approach was used. A total of 290 subjects (80 headteachers and 210 teachers) responded to the survey. As research instruments, the Job Satisfaction Scale (JSS) and the Maslach Burnout Inventory (MBI), were used to measure dimensions of headteachers’ and teachers’ burnout. The study results indicated that headteachers have more job dissatisfaction and depersonalisation than teachers. Males have less emotional exhaustion but higher depersonalisation than their female counterparts. Subjects participated in this study seemed to be different on depersonalisation and personal accomplishment dimensions on the scale in relation to their work years. More experienced subjects have higher depersonalisation and less job satisfaction than their less experienced counterparts. In contrast, more experienced subjects have higher personal accomplishment than the others. 相似文献

Lexical cohesion is a property of text, achieved through lexical-semantic relations between words in text. Most information retrieval systems make use of lexical relations in text only to a limited extent. In this paper we empirically investigate whether the degree of lexical cohesion between the contexts of query terms’ occurrences in a document is related to its relevance to the query. Lexical cohesion between distinct query terms in a document is estimated on the basis of the lexical-semantic relations (repetition, synonymy, hyponymy and sibling) that exist between there collocates – words that co-occur with them in the same windows of text. Experiments suggest significant differences between the lexical cohesion in relevant and non-relevant document sets exist. A document ranking method based on lexical cohesion shows some performance improvements. 相似文献

The purpose of this study was to compare different conceptual change methods within a topic on ‘sound propagation’. The study
was conducted with 80 grade 5 students (aged 11–12 year old) drawn from four cohort classes in an elementary school on the
north coast of Black Sea Region in Turkey. While one class was assigned as a control group, the others formed experimental
groups (one with a conceptual change text, one with analogies presented as computer animations and one with a combination
of conceptual change text, analogies and computer animations). A questionnaire with 10 two-tier questions was administered
as a pretest a week before the teaching intervention, and the same test was re-administered immediately after the intervention
as a post-test. The questionnaire was also employed as a delayed post-test 3 weeks after the teaching intervention. The experimental
groups performed significantly better in the post-test that the control group (p < 0.05). Within the experimental groups, the group exposed to a combination of the conceptual change text, analogies and
computer animations performed best on the post-test and the delayed post-test (p < 0.05). Overall the study indicated that the intervention that employed the entire suite of conceptual change pedagogies
produced the best learning outcomes. 相似文献

Although electromagnetism is an important component of upper secondary school physics syllabuses in many countries, there has been relatively little research on students’ understanding of the topic. A written test consisting of 16 diagnostic questions was developed and used to survey the understanding of electromagnetism of upper secondary school students in Turkey (n = 120) and England (n = 152). A separate test consisting of 10 questions on the visualization of spatial rotation was used to investigate the hypothesis that students’ ability to visualize three‐dimensional situations from two‐dimensional representations might influence learning of electromagnetism. Many students’ responses showed misunderstandings and inconsistencies that suggested they did not have a coherent framework of ideas about electromagnetism. Common errors included confusing electric and magnetic field effects, seeing field lines as indicating a “flow”, using cause–effect reasoning in situations where it does not apply, and dealing with effects associated with the rate of change of a variable. Performance on the spatial rotation test was, however, only weakly correlated with performance on the electromagnetism questions. The findings suggest the need to develop teaching strategies that help students to visualize magnetic field patterns and effects, and assist them in integrating ideas into a more coherent framework. 相似文献
