Conclusion The responses and the reasons given for those responses suggest that many of these first year students were not able to read
and interpret diagrams in a critical manner and recognise their limitations. Rather, they depend on a qualitative global appreciation
of the relationships involved and do not distinguish between the diagram and the model it represents.
The overall pattern of responses on the test was consistent with the common errors identified in textbook diagrams. Such diagrams
(see those which appear below) are notably qualitative and do not attempt to accurately portray relationships quantitatively.
It appears as if such diagrams represent reality for many students. This finding has important implications for science teaching
because it is known that the conceptual model held by a learner influences subsequent learning. 相似文献

Business students appreciate working on classroom projects that are both enjoyable and useful in preparing them for future careers. Promoting competition among project teams is also used as a method to motivate students. The Humanitarian Logistics Project (HLP) teaches undergraduate students the logistical implications of unsolicited material donations in disaster relief. To encourage competition, students are organized into teams of three and tasked with designing humanitarian public service announcements (PSAs) that improve their understanding of humanitarian issues in the general public. These announcements are then submitted to the national PSAid (Public Service Announcements for International Disasters) contest for American college students. The exercise is rigorous because it requires students to collect logistical data and use it to communicate the principle of smart compassion to the public in a creative fashion. Moreover, not only do students learn about topics related to humanitarian logistics by competing with other college students nation‐wide, but also do they make a socially responsible contribution to the public. Analysis of survey data shows that students’ learning outcomes from the HLP are significantly greater than those for other supply chain topics covered in class, and that student satisfaction with the HLP is high. 相似文献

The development of cable force during hammer-throw turns is crucial to the throw distance. In this paper, we present a method that is capable of measuring cable force in real time and, as it does not interfere with technique, it is capable of providing immediate feedback to coaches and athletes during training. A strain gauge was mounted on the wires of three hammers to measure the tension in the wire and an elite male hammer thrower executed three throws with each hammer. The output from the gauges was recorded by a data logger positioned on the lower back of the thrower. The throws were captured by three high-speed video cameras and the three-dimensional position of the hammer's head was determined by digitizing the images manually. The five best throws were analysed. The force acting on the hammer's head was calculated from Newton's second law of motion and this was compared with the force measured via the strain gauge. Qualitatively the time dependence of the two forces was essentially the same, although the measured force showed more detail in the troughs of the force–time curves. Quantitatively the average difference between the measured and calculated forces over the five throws was 76 N, which corresponds to a difference of 3.8% for a cable force of 2000 N. 相似文献

We recently published an article on arm coordination and performance level in 400-m front-crawl swimming in Research Quarterly for Exercise and Sport (Schnitzler, Seifert, &; Chollet, 2011). The index of coordination (IdC) was used to quantify interarm coordination. Our results showed that expert swimmers exhibited lower IdC than recreational swimmers over a 400-m trial. In addition to criticizing various methodological points, Havriluk (2012) challenged our conclusion that catch-up could be an efficient model of coordination and instead suggested that it might lead to injuries. An important point in this debate, however, is that our definition of catch-up coordination may differ from the one proposed by Havriluk (2012), which would explain why we consider catch-up coordination to be the dominant mode of coordination used by expert swimmers during training sessions. 相似文献

The current study explored the values preservice teachers use as motivation for pursuing a teaching career. Preservice teachers (N = 97) from a large Northeastern urban university were chosen to complete a survey measuring personal utility value, social utility value, and epistemic value. Data analysis was conducted using exploratory factor analysis, correlations, multivariate analysis of variance (MANOVA), and multivariate analysis of covariance (MANCOVA). Results indicated moderate and significant correlations among subscales; a two-group MANOVA demonstrated that females were rated higher on the subscale desire to work with children/adolescents and Secondary Education participants rated highest on social contribution; and a MANCOVA using sex as the covariate demonstrated that participants pursuing Early Childhood Education were rated higher on the personal utility value main scale and the time for family and job transferability subscales. 相似文献

This study investigated inclusion of epistemic value into Richardson and Watt Factors Influencing Teaching Choice (FIT-Choice) framework to produce a more robust, useful teacher motivation model. We specifically examined pre-service teachers’ social utility value (SUV), personal utility value (PUV) and epistemic value regarding pursuing future professional engagement and development. Using principal axis factoring, we found four main factors: PUV, SUV, epistemic value—future value of knowledge (EVF) and persistence/satisfaction. These factors were then used in a structural equation model (SEM) to predict pre-service teachers’ intentions to pursue future professional engagement. Results provided the following three insights: (a) SUV was the most consistent, positive predictor of professional engagement and predicted all dependent variables; (b) EVF was a newly identified factor and a positive predictor of pre-service teachers’ desire to pursue a leadership position and (c) PUV negatively predicted planned effort and a desire to pursue a leadership position. 相似文献

We transformed our first-year curriculum in biology with a new course, Biological Inquiry, in which >50% of all incoming, first-year students enroll. The course replaced a traditional, content-driven course that relied on outdated approaches to teaching and learning. We diversified pedagogical practices by adopting guided inquiry in class and in labs, which are devoted to building authentic research skills through open-ended experiments. Students develop core biological knowledge, from the ecosystem to molecular level, and core skills through regular practice in hypothesis testing, reading primary literature, analyzing data, interpreting results, writing in disciplinary style, and working in teams. Assignments and exams require higher-order cognitive processes, and students build new knowledge and skills through investigation of real-world problems (e.g., malaria), which engages students’ interest. Evidence from direct and indirect assessment has guided continuous course revision and has revealed that compared with the course it replaced, Biological Inquiry produces significant learning gains in all targeted areas. It also retains 94% of students (both BA and BS track) compared with 79% in the majors-only course it replaced. The project has had broad impact across the entire college and reflects the input of numerous constituencies and close collaboration among biology professors and students. 相似文献
