The aim of this study was to determine the physiological responses to orienteering by examining the interrelationships between the information provided by a differential global positioning system (dGPS) about an orienteer's route, speed and orienteering mistakes, portable metabolic gas analyser data during orienteering and data from incremental treadmill tests. Ten male orienteers completed a treadmill threshold test and a field test; the latter was performed on a 4.3 km course on mixed terrain with nine checkpoints. The anaerobic threshold, threshold of decompensated metabolic acidosis, respiratory exchange ratio, onset of blood lactate accumulation and peak oxygen uptake (VO2peak) were determined from the treadmill test. Time to complete the course, total distance covered, mean speed, distance and timing of orienteering mistakes, mean oxygen uptake, mean relative heart rate, mean respiratory exchange ratio and mean running economy were computed from the dGPS data and metabolic gas analyser data. Correlation analyses showed a relationship between a high anaerobic threshold and few orienteering mistakes (r = - 0.64, P < 0.05). A high threshold of decompensated metabolic acidosis and VO2peak were related to a fast overall time (r = -0.70 to -0.72, P < 0.05) and high running speed (r = 0.64 to 0.79, P < 0.05 and P < 0.01, respectively), and were thus the best predictors of performance. 相似文献

Student engagement has been identified as an influential mediator between classroom interactional quality and adolescent learning outcomes. This study examined the relationship between classroom quality and student behavioural engagement in secondary school classrooms. Three dimensions of classroom quality (emotional, organisational and instructional support) and the dimension of student engagement were observed in nine classrooms using the Classroom Assessment Scoring System. Self-ratings of behavioural engagement were provided by 181 Finnish secondary school students along with their teachers’ ratings of classroom-level student engagement. The results showed, first, that there was variation in both classroom quality and student behavioural engagement between the classrooms. Second, classroom organisational support was associated with observed and with teacher- and student-rated engagement, and instructional support was associated with student-rated and observed engagement. Third, emotional support did not have a direct effect on student engagement but contributed to student engagement indirectly via organisational and instructional support. There were no gender differences with respect to self-reported engagement. Class size had a positive effect on teacher-rated engagement. The results demonstrated specific associations between the domains of classroom quality and student behavioural engagement in secondary school classrooms. 相似文献

The aim of this study was to explore the relationships between prior knowledge, academic self‐beliefs, and previous study success in predicting the achievement of 139 students on a university mathematics course. Structural equation modelling was used to explore the interplay of these variables in predicting student achievement. The results revealed that domain‐specific prior knowledge was the strongest predictor of student achievement over and above other variables included in the model and, together with previous study success, explained 55% of the variance. Academic self‐beliefs strongly correlated with previous study success and had a strong direct influence on prior knowledge test performance. However, self‐beliefs predicted student achievement only indirectly via prior knowledge. The results imply that both prior knowledge and self‐beliefs should be taken into account when considering instructional support issues, because they can provide valuable insights about the future performance of the students. 相似文献

Educators in the computing fields are often familiar with the characterization of computing as a combination of theoretical, scientific, and engineering traditions. That distinction is often used to guide the work and disciplinary self-identity of computing professionals. But the distinction is, by no means, an easy one. The three traditions of computing are based on different principles, they have different aims, they employ different methods, and their products are very different. Educators in the field of computing should be aware of the fundamental differences between the traditions of computing so that they can offer their students a truthful and balanced view about computing branches. In this article the three traditions of computing are presented and some of their underlying assumptions, principles, application areas, restrictions, and weaknesses are portrayed. Also, some of the landmark arguments in the debates about the identity of computing disciplines are discussed. 相似文献

In this paper, we focus on Finnish pre-service elementary teachers’ (N?=?269) and upper secondary students’ (N?=?1,434) understanding of division. In the questionnaire, we used the following non-standard division problem: “We know that 498:6?=?83. How could you conclude from this relationship (without using long-division algorithm) what 491:6?=?? is?” This problem especially measures conceptual understanding, adaptive reasoning, and procedural fluency. Based on the results, we can conclude that division seems not to be fully understood: 45% of the pre-service teachers and 37% of upper secondary students were able to produce complete or mainly correct solutions. The reasoning strategies used by these two groups did not differ very much. We identified four main reasons for problems in understanding this task: (1) staying on the integer level, (2) an inability to handle the remainder, (3) difficulties in understanding the relationships between different operations, and (4) insufficient reasoning strategies. It seems that learners’ reasoning strategies in particular play a central role when teachers try to improve learners’ proficiency. 相似文献

Formative development method (FODEM) is a multithreaded design approach that was originated to support the design and development
of various types of educational technology innovations, such as learning tools, and online study programmes. The threaded
and agile structure of the approach provides flexibility to the design process. Intensive stakeholder feedback is a vital
aspect of FODEM. As a formative method that emphasizes research-orientation and evaluation through the entire development
process, this article proposes that FODEM is fundamentally also a research and development method. FODEM provides tools to
conceptualize the development process via its distinguishing feature, namely a dynamic thread structure. FODEM can be used
to manage, analyse and visualise the overall design process at different stages. FODEM can also be used to create different
conceptulisations of a design process in order to identify successes and failures. 相似文献

Background Education fundamentally shapes an individual's life chances and social status. Duration and level of education are associated with people's incomes, socio-economic status, living standard, lifestyle and the respect and esteem they enjoy. Failure to fulfil educational potential may have long-term consequences for later occupational and social life, as well as creating problems for society at large. Purpose The aim of this prospective follow-up study was to investigate which health, lifestyle, family and school factors in adolescence had the strongest impact on educational level attained in adulthood. Sample The original study population included all 9th-grade school pupils aged 16 years attending secondary school in spring 1983 in Tampere, Finland (n = 2269). Subjects were followed up at 32 years of age in 1999 (n = 1471). Design and methods In 1983, 2194 pupils (96.7%) with a mean age of 15.9 years (SD 0.3 years) completed questionnaires during school hours. The questionnaire included questions about psychological and somatic health, lifestyle, family background, school factors and life events. In 1999, postal questionnaires were sent to the same study population when they were 32 years old. The follow-up questionnaire included basically the same questions about health and lifestyle as in adolescence and age-appropriate versions of questions about social relations and life events. Education was measured by the highest level of attained education. The follow-up cohort totalled 2091 persons (92%), and the response rate was 70.3% (n = 1471). The univariate associations between independent variables in adolescence and attained educational level in adulthood were analysed using the χ2 test, and Student's t-test where appropriate. Multivariate logistic regression analyses using forward stepwise procedure were used to determine which factors in adolescence had the strongest impact on adult educational level. Results Several health, lifestyle, family and school factors in adolescence were univariately associated with educational attainment in adulthood. Multivariate analyses showed that, in both genders, low school achievement and manual class of origin were the strongest predictors of low educational level in adulthood. Additional significant predictors among females were poor perceived health status, spending less leisure-time on hobbies and more on dating, and among males, poor relationships with teachers and heavy drinking. Conclusions Mid-adolescence is an important period for future educational life trajectory. Based on our study results, more attention should be paid to adolescents with school difficulties, unhealthy lifestyle and poor perceived health. It is also important to promote educational equality in relation to family background. 相似文献
