The aims of this cross-grade study were (1) to determine the level of understanding of energy concepts of students at different
academic grades and the differences in understanding between these grades and (2) to analyse the conceptual development of
these students. Two hundred and forty-three students at 3 different levels (high school, undergraduate, and postgraduate)
participated in this study. The students’ understandings of energy concepts were determined using a questionnaire, which requested
them to define the concept verbally, and to represent it graphically. The most important findings of this study may be summarised
as follows. Students from the different groups generally succeeded in defining ‘energy’ in a similar way, namely as the ‘ability
to do work’. Nevertheless, some students (including those at university) also provided different alternative conceptions related
to the energy concept. In addition, some students also found difficulty in visually analysing the relationships between different
variables using graphs. This finding could help explain why attainment levels of all groups falls short in questions that
involve the graphical representation of data. 相似文献

This exploratory study examines the background characteristics, socio-cultural values and pedagogical beliefs that entering student teachers bring with them into the faculties of education and explores their possible implications for teacher education in the Turkish context. The study comprised 18,226 first-year student teachers from 51 faculties of education who participated in the study by responding to a three-section questionnaire developed by the research team. Their responses indicate that students entering education faculties typically come from families of lower-middle socio-economic status living in urban areas, tend to possess more traditional than secular-rational values and have not yet formed clear pedagogical beliefs. 相似文献

The translation of an instrument from one language to another is a challenging yet useful procedure, especially for constructs not widely studied in the target language. Culture shock is one such construct. The Culture Shock Questionnaire （CSQ） developed in England was translated to Turkish. Translation/back translation with 12 translators, the committee approach, and empirical testing in the university student population were the techniques employed. The results support CSQ as a potential instrument in the Turkish language as well as suggest that challenges in the translation of a research instrument, like challenges in the translation of other texts, involve serious dilemmas about the extent of loyalty to the original instrument. The current study recommends the use of multiple techniques in translation and reports on committee decisions in detail. 相似文献

In architectural design education, the main objective is to help students, especially first‐year students, improve their design ideas, creativity, perception of three dimensions and ways of expressing them. Thus, as an embedded concept in architecture, art has been emphasized here as a design method. In other words, the necessary help to enable students to think more freely has been provided by ceramic art. The concept dealt with in this article is an interdisciplinary approach to space design as an experimental method in design education. Just as fine art students are inspired from the principles of architecture, clay, as basic material to fine art students, makes a creative material and design tool for architecture students. A workshop was organised in the design courses by the first author, the instructor, for the first‐ and third‐year architecture students. The second author, a ceramics artist and lecturer, has participated in the workshop as a visiting instructor and contributed with her own studies related to space, house, building and materials. 相似文献

Amiodarone hydrochloride is a potent anti-arrhythmic agent, known as a multiple ion-channel blocker in the heart.Although it has been detected in the rat brain, there are no data related to its central nervous system (CNS) effects. In this study, we evaluated anticonvulsant and hypnotic effects of amiodarone. Convulsions were induced by phentylenetetrazole (PTZ) (100 mg/kg) or caffeine (300 mg/kg) in mice. In both models, amiodarone prolonged both latency period and time to death, and acted as an anticonvulsant drug. It was found to be more effective in the PTZ model than in the caffeine model; none of the animals treated with 150 mg/kg dose amiodarone had died in the PTZ model. For hypnotic effect, sleeping was induced with pentobarbital (35 mg/kg) in rats. Amiodarone dose-dependently increased the sleeping time (677.7%～725.9%). In the sleeping test, all rats in 200 mg/kg amiodarone group died. In conclusion, anticonvulsant and hypnotic effects of amiodarone have shown the depressant effects on CNS. These effects may be dependent on its pharmacological properties. 相似文献
