The main purpose of this study was to explore the factors mediating the translation of second grade teachers’ nature of science (NOS) views into classroom practice after completing a graduate level NOS course. Four second grade in-service elementary teachers comprised the sample of this study. Data were collected from several sources during the course of this study. The primary data sources were (a) assessment of the elementary teachers’ NOS views before and after the graduate level NOS course using the Views of Nature of Science Questionnaire Version B (VNOS-B) (Lederman et al., 2002) coupled with interviews, and (b) a classroom observation and videotaped recording of the elementary teachers’ best NOS lessons coupled with interview. We identified three distinct but related factors that mediated the translation of NOS views into classroom practice: the teachers’ perspectives about the developmental appropriateness of the NOS aspect, the teachers’ selection of target NOS aspects, and the relative importance placed by teachers on each NOS aspect. 相似文献

Background:
The ultra-large von Willebrand factor (vWF) multimers are very active and must be degraded by ADAMTS13 for optimal activity. A severe functional deficiency of ADAMTS13 has been associated with thrombotic thrombocytopenic purpura. The correct interpretation of patient vWF and ADAMTS13 plasma levels requires an understanding of the biological variation associated with these analytes. In the present paper, we aimed to determine the biological variation of ADAMTS13 and vWF in human adults.Materials and methods:
Blood samples were collected weekly from 19 healthy subjects for 5 consecutive weeks. vWF activity and antigenicity were determined using aggregometric and immunoturbidimetric methods. ADAMTS13 antigenicity and activity were determined by ELISA.Results:
The within-subject biological variations for vWF activity and antigenicity were 8.06% and 14.37%, respectively, while the between-subject biological variations were 18.5% and 22.59%, respectively. The index of individuality for vWF activity was 0.44, while vWF antigenicity was 0.64. Similarly, ADAMTS13 activity and antigenicity within-subject biological variations were 12.73% and 9.75%, respectively, while between-subject biological variations were 9.63% and 6.28%, respectively. The ADAMTS13 indexes of individuality were 1.32 and 1.55, respectively.Conclusion:
We report high biological variation and individuality in vWF antigenicity and activity levels. However, ADAMTS13 antigenicity and activity displayed high biological variation, but low individuality. Thus, population-based reference intervals may be useful for monitoring ADAMTS13 antigenicity and activity, but not for vWF, which displays high individuality. These findings should be considered when determining the reference interval and other clinical variables associated with ADAMTS13 and vWF levels. 相似文献3.
Daylighting, a controlled architectural tool that influences users' perception and behavior, in university libraries and their influences on users' preference and satisfaction was examined in this study. The effects of daylighting in coordination with visual comfort, on university library users were measured in relation to four environmental processes, namely privacy, personal space, territoriality, and crowding. It was found that daylight and four environmental processes are related. It is believed that the consideration of this relationship will encourage students to use their libraries fully as an essential component of university education and campus life. 相似文献

Abstract The paper summarizes the results of a series of focus group interviews with Chinese teaching assistants and US undergraduates on their perceptions about teaching and teachers in their own and US cultures. Focus group interviews were held with Chinese math‐based science teaching assistants (CTAs) who were at three different stages of the teacher preparation process. Similarly, American undergraduates’ perceptions were elicited through focus group interviews and questionnnaires. CTAs viewed American college instructors as exciting, but unclear in their organization and presentation. Undergraduates thought ideal US professors should spend more time with their students, and have interpersonal skills in teaching. They did not value the professor's knowledge of the subject matter as much as CTAs did. Implications for future TA development programmes are also discussed. 相似文献

Museums are used in every discipline to collect, classify, and present information for scientific purposes. They also serve as an effective educational medium. Since the establishment of a boutique anatomy museum at Bahçeşehir University, lectures, conferences, and seminars have been organized there over the past four years on the history of human anatomy and the human body. In order to raise awareness about the need to make anatomy accessible to kindergarteners and school-aged children, rather than exclusively to undergraduate students, activities that are suited to a wide range of ages have been developed at the museum and at the anatomy laboratory. Four different sessions were conducted, including activities such as lectures using plastic models as props, shaping organs out of playdough, anatomy puzzles, watching cartoons, and examining specimens through a microscope. Healthy and pathologic anatomies were chosen to match daily themes. Among the kindergarteners and elementary school children, no grading was done, nor was any questionnaire administered; however, a survey was administered in the 10–12 age group (N = 64). According to the students' written feedback, 93.75% said they “are happy with microscope activities” while 84.37% said they “had so much fun” participating in the playdough activities. However, 18.75% criticized the activities, saying they “could have been longer.” In conclusion, it is believed that these “getting to know our bodies” activities that were hosted in the anatomy museum, including conferences, workshops, material preparation, and instructional movies, may play an important role in the development of a healthy society. 相似文献

The purpose of this paper is to describe the development process and the key components of a computer-assisted histology material. Computer-assisted histology material is designed to supplement traditional histology education in a large Midwestern university. Usability information of the computer-assisted instruction (CAI) material was obtained through formative research methodology. Findings indicate that computer-assisted instruction should be used as complimentary to traditional histology instruction. 相似文献

Even though in the early years of the Republic of Turkey Darwin’s theory of evolution was treated as a scientific theory and taught fairly in schools, despite all the substantial evidence accumulated supporting the theory of evolution since then, Darwin and his ideas today have been scorned by curriculum and education policy makers. Furthermore, Turkish students and academics have been faced with unprecedented creationist propaganda for many years. In this paper, we first provide a glimpse of the theory of evolution and creationism in Turkey, we then report the results of our survey study (N = 1,098) about the undergraduates’ acceptance and understanding of Darwinian evolution and some of the socioeconomic variables affecting those measures. Our cross sectional study shows that acceptance and understanding of the theory of evolution is quite low. We criticize the current state of evolution education in Turkey and call for a change towards a scientific treatment of the theory evolution in schools. 相似文献

The purpose of the present study was to explore through qualitative methodology the practice of visiting shrines, a religious practice indigenous to Turkish Muslims, and its potential mental health benefits. Thirteen individuals were interviewed at two shrines in Istanbul, Turkey. The researchers focused on visitors’ presenting issues, beliefs regarding the practice, the mental health benefits of the visit, and the behaviors that the visitors engaged in during their visit. The data were analyzed using the Consensual Qualitative Research method. Five domains emerged from the data: (i) degree of religiosity and duties, (ii) knowledge and beliefs about shrines, (iii) purpose of visits, (iv) activities during the visit, and (v) experience and impact of the visit. The findings were discussed based on the mental health benefits of visiting shrines and the counseling and cultural implications. 相似文献
