Characteristics of Pre-Service Teachers’ Online Discourse: The Study of Local Streams 总被引:2,自引:2,他引:0
Ling L. Liang Jazlin Ebenezer Deborah S. Yost 《Journal of Science Education and Technology》2010,19(1):69-79
This study describes the characteristics of pre-service teachers’ discourse on a WebCT Bulletin Board in their investigations
of local streams in an integrated mathematics and science course. A qualitative analysis of data revealed that the pre-service
teachers conducted collaborative discourse in framing their research questions, conducting research and writing reports. The
science teacher educator provided feedback and carefully crafted prompts to help pre-service teachers develop and refine their
work. Overall, the online discourse formats enhance out-of-class communication and support collaborative group work. But the
discourse on the critical examination of one another’s point of views rooted in scientific inquiry appeared to be missing.
It is suggested that pre-service teachers should be given more guidance and opportunities in science courses in carrying out
scientific discourse that reflects reform-based scientific inquiry. 相似文献

Empirical research on sibling abuse has been overwhelmingly absent from the professional literature. This exploratory study used a survey instrument to investigate the question of whether the experience of sibling abuse influences the sense of well‐being in college students. A linear multiple regression analysis indicated that experience with sibling abuse, either as a survivor or as a perpetrator, does have an impact on perception of well‐being. Implications of these findings for future research are discussed. 相似文献

Basic measurements and applications of six selected general but critical operational performance‐based indicators—effectiveness, efficiency, productivity, profitability, return on investment, and benefit‐cost ratio—are presented. With each measurement, goals and potential impact are explored. Errors, risks, limitations to measurements, and a final check for validity, applicability, accountability, and usability of these measurements are discussed. This article provides a simple, practical guide to performance measurement for organizations and human performance technology practitioners' accountability and continuous improvement. 相似文献

ABSTRACT: To create effective educational interventions that address the food safety informational needs of youth, a greater understanding of their knowledge and skills is needed. The purposes of this study were to explore, via focus groups, the food‐handling responsibilities of middle school youth and obstacles they face in practicing safe food handling and develop recommendations for the design of food safety interventions for youth. Most youth reported that they prepared food at least once weekly and rated learning to prevent foodborne illness as important. Youth knew that food could make them sick, described foodborne illness as resulting from “something” getting into food, not cooking food “right,” or the food going bad. Most responses lacked details, suggesting knowledge was basic. Nearly all were interested in learning about food safety. Barriers that deterred them from learning about food safety were time and feeling they were not susceptible to foodborne illness. To overcome barriers, youth suggested focusing on the seriousness of and risks for foodborne illness, using a serious but comical educational approach, and using hands‐on educational media. Parents highly rated the importance of and degree to which they wanted youth to learn about food safety. Parents felt that their children had moderate levels of food safety knowledge, but many questioned whether they practiced food safety procedures when unsupervised. Parents felt that food safety education needed to be taught and reinforced in school and at home. After having reviewed youth and parent data, food safety experts proposed recommendations for youth‐focused food safety education that paralleled current consumer food safety initiatives. 相似文献

From the early 19th century until the most recent two decades, open‐space and satellite museums featuring anatomy and pathology collections (collectively referred to as “medical museums”) had leading roles in medical education. However, many factors have caused these roles to diminish dramatically in recent years. Chief among these are the great advances in information technology and web‐based learning that are currently at play in every level of medical training. Some medical schools have abandoned their museums while others have gradually given away their museums' contents to devote former museum space to new classrooms, lecture halls, and laboratories. These trends have accelerated as medical school enrollment has increased and as increasing interest in biological and biomedical research activities have caused medical schools to convert museum space into research facilities. A few medical schools, however, have considered the contents of their museums as irreplaceable resources for modern medicine and medical education and the space these occupy as great environments for independent and self‐directed learning. Consequently, some medical schools have updated their medical museums and equipped them with new technologies. The Anatomical Museum of Leiden University Medical Center in The Netherlands and the Medical Museum of Kawasaki Medical School in Kurashiki, Okayama, Japan, are two examples of such upgraded museums. Student surveys at Leiden University have indicated that all students (100%) found audio‐guided museum tours to be useful for learning and majorities of them found guided tours to be clinically relevant (87%). However, 69% of students felt that museum visits should be optional rather than compulsory within the medical training curriculum.

The gross anatomy dissection course is a cost‐intensive piece of undergraduate medical education that students and professionals alike describe as very important within the overall medical curriculum. We sought to understand more explicitly students' valuation of gross anatomy as an “important” course and so developed a quantitative longitudinal questionnaire. Medical students (n = 124) enrolled in the winter term 2006/2007 gross anatomy course at the Ulm University Faculty of Medicine were surveyed anonymously prior to, in the middle of, and at the end of the dissection course. Subgroups of students expressing rising or falling opinions of course value were identified and correlated with student opinions about the course's ability to convey professional competencies. Five‐point Likert scales were used for each survey item, which included such standardized instruments as the NeoFFI, BSI, and FBM. The study confirmed that medical students believe dissection to be valuable. Students indicated that participation in the course facilitated acquisition of anatomy knowledge as well as skills related to teamwork, coping with stress, and, to a lesser extent, time management. Students also noted that they developed less empathy than expected beforehand. Significant subgroup differences were observed relative to the competencies of teamwork, stress coping strategies, and empathy, as well as in students' stress levels associated with having to take a dissection course. Our study builds on previous work that has shown dissection courses help students develop professional competencies. The increase in professionalism might be a reason for the generally high value students place on the gross anatomy dissection course, Anat Sci Educ 3:3–11, 2010. © 2010 American Association of Anatomists. 相似文献

In this study, we explored the relationship between beginning readers' phonological awareness and other aspects of phonological processing, specifically as manifested in short-term memory and comprehension tasks. The theoretical questions underlying the study were (a) what roles phonological processes play in children's beginning reading, from word identification through sentence comprehension, and (b) whether those roles are sufficiently related that potential difficulties at one level directly affect processing at other levels. Phonologically induced effects were observed for word-list memory and for sentence judgments for both novice readers (at the end of kindergarten) and relatively more experienced readers (end of Grades 1 and 2). For both age groups, correlational analyses revealed relationships among phonological awareness, phonological processing in list memory, and word reading. However, phonological processing in sentence comprehension was not related to other types of phonological processing. These results indicate that although phonology plays a role during comprehension, phonological processing may not be as limiting a factor in comprehension as in word reading. 相似文献

Three aspects of racial-ethnic identity (REI)-feeling connected to one's racial-ethnic group (Connectedness), being aware that others may not value the in-group (Awareness of Racism), and feeling that one's in-group is characterized by academic attainment (Embedded Achievement)-were hypothesized to promote academic achievement. Youth randomly selected from 3 low-income, urban schools (n=98 African American, n=41 Latino) reported on their REI 4 times over 2 school years. Hierarchical linear modeling shows a small increase in REI and the predicted REI-grades relationship. Youth high in both REI Connectedness and Embedded Achievement attained better grade point average (GPA) at each point in time; youth high in REI Connectedness and Awareness of Racism at the beginning of 8th grade attained better GPA through 9th grade. Effects are not moderated by race-ethnicity. 相似文献

Mainland China has a highly centralised curriculum development system. A study of two schools in northeast China, one in a rural area and the other in an urban area, indicates that the primary mathematics curriculum has been widely adopted by teachers at the classroom level. Feeling the intense pressure generated by the national mathematics Olympiad,1 teachers in the urban school tended to give more difficult mathematics problems to their students in the hope that above‐average students would perform well in the competition. In the rural school, the ability of students was more varied and generally lower. Teachers there worked very hard to push their students to meet the national requirements. The driving force behind this was the county‐wide public examination in which students' performance was taken as an indicator of teachers' competence. Teachers in both schools also have not taken effective steps to adapt the curriculum for students' individual differences. A comparison of the practices between the teachers in the two schools suggests that teachers' beliefs, their professional knowledge and skills shape their inclination and ability in curriculum adaptation and differentiation. 相似文献

Phonological awareness (PA), phonological memory (PM), and phonological access to lexical storage (also known as RAN), play
important roles in acquiring literacy. We examined the convergent, discriminant, and predictive validity of these phonological
processing abilities (PPAs) in 147 3-, 4-, and 5-year-old children whose native language was Spanish. Confirmatory factor
analysis (CFA) supported the validity of each PPA as separate from general cognitive ability and separate from each other.
Moreover, structural equation modeling found RAN uniquely associated with knowledge of Spanish letter names and Spanish letter
sounds. PA was found the best predictor of children’s ability to distinguish alphabetic text from nonalphabetic text. Finally,
general cognitive ability was only indirectly associated with emergent literacy skills via PPAs. These results highlight the
importance of PPAs in the early literacy development of native Spanish speaking preschool children. 相似文献
