Abstract

In this study, we assessed the extent to which 2000-m rowing ergometer performance predicted final rankings at the World Junior Rowing Championship in a sample of 398 junior rowers competing in 13 events. The rowers' ergometer performance times were examined using a questionnaire, and in all 13 events they correlated (P ≤ 0.039) with the final rankings at the Championship. The strongest correlations were observed for ergometer performance times in junior women's single sculls (r = 0.92; P < 0.001), followed by junior men's single sculls (r = 0.80; P < 0.001) and junior women's double sculls (r = 0.79; P < 0.001). The observed correlations were higher for smaller boats – singles, doubles, and pairs (r = 0.64–0.92; P ≤ 0.025) – than for larger boats – quads, fours, and eights (r = 0.31–0.70; P ≤ 0.039). Linear regression analyses were used to construct regression equations to predict final rankings based on 2000-m rowing ergometer performance times for each event. Although correlations in 10 of the 13 events were above r = 0.5, the large standard errors of the estimate impaired the prediction of rankings in all of the studied events. Using these equations, the most probable rowing ergometer performance times required for a particular ranking in a given rowing event might easily be calculated.  相似文献   

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

Victoria Crisp  Martin Johnson  Nadežda Novaković 《British Educational Research Journal》2012,38(5):813-839

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).  相似文献   

Student background factors influencing student achievement in Serbia     

Jelena Teodorović 《Educational studies》2012,38(1):89-110

This paper describes student‐level findings of the first large‐scale comprehensive school effectiveness study of the primary education in Serbia. Twenty‐five student‐level variables were examined in a three‐level HLM model using a study sample of almost 5000 students, over 250 classrooms and over 100 schools. Differences between the students were in large part responsible for differences in achievement scores in mathematics and Serbian language. Parental education, Roma minority status, developmental or family problems, gender, student motivation, parental involvement in student work and homework were some of the factors associated with student achievement. Serbian policy‐makers are alerted to possible actions in order to improve mathematics and Serbian language achievement.  相似文献   

Teaching about thermal expansion: investigating the effectiveness of a cognitive bridging approach     

Andrej Vidak  Senad Odžak  Vanes Mešić 《Research in Science & Technological Education》2019,37(3):324-345

Background: It is widely known that for many students it is very difficult to correctly predict how thermal expansion affects the appearance of a metal plate with a circular hole. Interviews with school teachers show that the source of this difficulty could stem from the fact that students’ internal visualizations of an arbitrary object’s thermal expansion often boil down to visualizing changes along one dimension only.

Purpose: In this study, we investigated how students’ mental models about one-dimensional expansion can be extended for purposes of running mental simulations about expansion along two dimensions.

Sample: To that end a pretest-posttest quasi-experiment has been conducted, with 100 students in the control group and 95 students in the experimental group.

Design and methods: Whereas control group students received traditional instruction with a focus on formal representations, in the experimental group the students were led to draw an analogy between heating of a straight rod and a circular rod of same length, whereby the internal structure of the rods was represented by springs.

Results: Eventually, it has been found that students from the experimental group were significantly more successful at predicting the effects of thermal expansion, especially within contexts of objects with holes.

Conclusion: Analogies and extreme case reasoning can be effectively used for helping the students to correctly transfer their mental models about one-dimensional expansion to situations that require reasoning about expansion along two dimensions.  相似文献   

The role of test hope and hopelessness in self-regulated learning: Relations between volitional strategies,cognitive appraisals and academic achievement     

Irena Burić  Izabela Sorić 《Learning and individual differences》2012,22(4):523-529

The aim of this study was to examine the relationships amongst students' test emotions of hope and hopelessness, their antecedents of cognitive control and value appraisals and volitional strategies during learning, as well as their effects on academic achievement in the domain of mathematics, using the control–value theoretical framework. Sample consisted of 365 Croatian high school students. Correlational and structural equation analysis substantiated the assumptions concerning the relationships between test emotions, cognitive appraisals, volitional strategies and academic achievement. The results showed that cognitive appraisals partially mediate the relationship between volitional strategies and test emotions, and, further, that hopelessness play a partially mediating role in the relationship between volitional strategies and academic achievement. These findings once again emphasise the complex dynamics of cognitive, emotional and behavioural components of a self-regulated learning process.  相似文献

Intergroup resource allocation among children from minority and majority groups in three settings of former conflict     

B. Corbett  J. Dautel  J. Tomašić Humer  A. Tomovska Misoska  L. K. Taylor 《Child development》2023,94(6):e393-e402

Intergroup resource allocation was examined among 333 children aged 7–11 (51.9% female) within three settings of former intergroup conflict (January–June 2021). Children represented both ethno-religious minority and majority groups (Republic of North Macedonia: Albanians, Macedonians; Croatia: Serbs, Croats; Northern Ireland: Catholics, Protestants), from predominantly White and middle-class families. Ingroup bias in average resource allocation amounts was demonstrated by both minority and majority children, across settings, in the context of novel targets (historic conflict rivals). Majority children were also more likely to give equally (which maintains the status quo) than minority children. Giving equally increased with age for both minority and majority children, despite being in “zero-sum,” conflict settings. Equitable intergroup resource allocation in such settings has implications for conflict transformation.  相似文献
