In order to help the selection and training of teachers for kindergartens, a scale for diagnosis of the special psychological predispositions needed for kindergarten teachers has been developed. It consists of 130 items derived from a personality test and an ability test.
By the use of stratified sampling strategy, 660 teachers from different kindergartens in Beijing were chosen to form a sample group in its development. The result of the test was displayed in the form of T-score and percentile respectively. After several times of practice, its reliability and validity have been verified. 相似文献

Study provides qualitative analysis of data that answers the following research question: how college science faculty teach science and NOS and incorporate aspects of NOS and the history of science into their undergraduate courses? Study concentrates on four cases and more specifically on three introductory science classes and on four instructors who taught those courses. These instructors were chosen as case studies to explore in greater detail what occurs inside introductory science courses in one particular higher institution in the Northeastern United States. Participants’ teaching styles are presented through a combined and detailed presentation of interview data and classroom observations supported with examples from their classroom activities. Constant comparative approach was used in the process of organizing and analyzing data. Findings revealed that participants preferred to use the traditional teacher-centered lecturing as their teaching style and whose main concern was to cover more content, develop the problem solving skills of their students, and who wanted to teach the fundamental principles of their subjects without paying special importance to the NOS aspects. The study also revealed that other variables of teaching science, such as large class size, lack of management and organizational skills, teaching experience, and instructors’ concerns for students’ abilities and motivation are more important for these scientists then teaching for understanding of NOS. 相似文献

This article reports on a study of six Grade 11 learners’ levels of understanding of concepts related to the function definition and representation. Task-based clinical interviews were used to elicit the learners’ interpretations and reasoning when working with these function-related concepts. Indicators for Action–Process–Object–Schema (APOS) theory conception levels were formulated and used to categorise learners’ written and interview responses into conception levels of understanding of the function concept. According to the South African Curriculum Assessment Policy Statement (CAPS) curriculum, Grade 11 learners are expected to be operating at the object and schema levels after instruction. however, the results indicated that learners were operating at the action and process levels as their understanding was characterised by vague definitions of function-related concepts and memorisation of procedures for translating between symbolic and graphical representations. 相似文献

Application of system dynamics for assessment of sustainable performance of construction projects 总被引：8，自引：0，他引：8
INTRODUCTION Sustainable development is commonly definedas meeting the needs of the present without compro-mising the ability of future generations to meet theirown needs (WCED, 1987). All industries, includingthe construction industry should contribute to themission. Compared to other industries, constructionactivities are generally considered to have more im-pact on the environment, which provides the basicconditions for the sustainability and development oflife on the Earth.

A volume-based method for measuring particle-size distribution (PSD) fractal dimensions of porous mediums was developed by employing laser size-analyzing technology. Compared with conventional approaches of using hydrometer or screen to determine PSD, this method can avoid calculation errors and measure smaller size-scale porous medium. In this paper the experimental porous mediums were brown soil, kaolin and sand soil. A micro-order of magnitude ( 10 ^-5 m) in particle-size interval could be shown in PSD results of brown soiland kaolin. The experiments indicated that brown soil had a nearly mono-fractal PSD character, while kaolinand sand soil showed multi-fractal PSD characters. By the adsorption isotherm experiments, the PSD fractal dimensions of the sand soil were also found to keep a linearly increasing relation with the linear adsorptive parameters of the soils in different intervals to adsorb benzene from aqueous solution. 相似文献
