This study explored what kind of mathematics is needed in cabinetmakers’ everyday work and how problem solving is intertwined in it. The informants of the study were four Finnish cabinetmakers and the data consisted of workshop observations, interviews, photos, pictures and sketches made by the participants during the interviews. The data was analysed using different qualitative techniques. Even though the participants identified many areas of mathematics that could be used in their daily work, they used mathematics only if they were able to. The cabinetmakers’ different mathematical skills and knowledge were utilized to their skill limit. Cabinetmakers were found to constantly face problem solving situations along with the creative processes. Being able to use more advanced mathematics helped them to solve those problems more efficiently, without wasting time and materials. Based on the findings, the paper discusses the similarities and differences between problem solving and creative processes. It is suggested that the combination of craftsmanship, creativity, and efficient problem solving skills together with more than basic mathematical knowledge will help cabinetmakers in adapting and surviving in future unstable labour markets. 相似文献

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

A characteristic feature of scientific knowledge is the high degree of coherence and connectedness of its conceptual structure.
This notion is also behind the widely accepted instructional method of representing the concepts as networks. We suggest here
that notions of explanatory coherence and deductive coherence naturally connect the structure of knowledge to the processes
which are important in constructing the concept networks. Of these processes, experimental method and modelling are shown
to be closely connected with explanatory and deductive coherence, respectively. From this viewpoint, we compare here how experts
and novices represent their physics knowledge in the form of concept networks, and show that significant differences between
experts’ and novices’ quality of knowledge become directly reflected in the structure of the networks. The results also show
how concept networks make visible both the structure of knowledge and the methodological procedures, which support its formation. 相似文献

This article analyses how Finnish vocational teachers make sense of the meanings of gender in their work. The context of the study consists of the two most gender segregated environments of vocational education: the female-dominated Sector of Health and Social Services and the male-dominated Sector of Technology and Transport. Our analysis draws on 23 teacher interviews conducted in two vocational institutions, offering vocational upper secondary education and training to both young and adult students. The data is analysed from post structural and material feminist theoretical positions, using various conceptualizations of gender. Our findings suggest that both male and female teachers have adopted the idea of gender neutrality, whilst they simultaneously provide dichotomical and hierarchical perceptions of men and women as vocational teachers. Consequences of minority position in the staff room are different for females and males. In the field of technology and transport, women in the minority, on the other hand, need to struggle continuously with masculine vocational hierarchies to gain professional respect. 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 contrast to its inception as intermission entertainment at the Crufts Dog Show in the UK in the late 1970s, dog agility has become a worldwide steadily professionalized and entrepreneurialized sport with reputable coaches and training programs over the last decade. This change raises concerns about the pressures placed on dogs. We look at the potential incommensurability of ‘loving’ a dog as a companion animal and making the dog engage in competitive sports. We evaluate texts, photographs and videos from successful agility coaches and identify four types of loving relationships through which the coaches express their commitment to the sport. While an affinity for dogs appears important for building the coaches’ reputation and provides the justification for engaging the dog in physically and mentally demanding sports, the question remains whether this dogmanship can be straightforwardly turned into action. 相似文献
