Students’ views of uncertainty in formal and personal science     

Meadow Schroeder  Anne McKeough  Susan A. Graham  Stephen P. Norris 《Research in Science & Technological Education》2019,37(2):239-257

Background: Uncertainty is a crucial element of scientific knowledge growth. Students should have some understanding of how science knowledge is developed and why scientific conclusions are considered more or less certain than others. A component of the nature of science, it is considered an important aspect of science education and allows students to recognize the limitations of scientific research.

Purpose: This study examined Grades 5 and 9 students’ views of uncertainty in their personal scientific research and the formal scientific research of professionals.

Sample: This study included 33 students in Grade 5 (n = 17) and Grade 9 (n = 16). The students were recruited from a charter school that emphasised inquiry instruction.

Design and methods: Data were collected through interviews. Students were asked their views of their inquiry-based projects and their views of professional science.

Results: Interview data and statistical analyses indicated that students recognized uncertainty in personal science, which varied across elements of the scientific process. Additionally, their views of uncertainty in formal science tended to change across grades and knowledge of uncertainty in personal and formal science were positively correlated.

Conclusion: These findings offer insights into the processes by which students come to understand uncertainty in science and point to ways of fostering such knowledge through teaching practices.  相似文献   

Unique Contributions of Maternal Reading Proficiency to Predicting Children’s Preschool Receptive Vocabulary and Reading Proficiency     

Linda M. Phillips  Stephen P. Norris  Denyse V. Hayward  Meridith A. Lovell 《Early Childhood Education Journal》2017,45(1):111-119

This study investigated whether mothers’ measured reading proficiency and their educational level predict, over and above each other, their children’s receptive vocabulary and reading proficiency when confounding factors of speaking a minority language, ethnicity, number of children in the family, and marital and employment status are controlled. The sample included 155 children (aged 3–5 years) and their mothers (aged 20–44 years) of low income and low educational background from Western Canada. Findings support the conclusion that maternal reading level predicts both their children’s receptive vocabulary and reading proficiency prior to schooling after maternal education is taken into account. The findings also show, after the effects of maternal reading ability are removed, maternal education predicts their children’s reading ability prior to school but not their receptive vocabulary proficiency. Thus, maternal reading proficiency and maternal education appear not to serve as proxies for each other, and the use of both variables should be used in studies where children’s reading and receptive vocabulary proficiency are dependent measures. Early childhood educators dedicated to the improvement of the language and literacy levels of children in their care may consider the implementation of programs that focus on improving mothers’ reading proficiency whereby their children’s levels also improve. Early childhood education is the prime time to provide a richer and more fruitful approach to reduce the persistent knowledge gap of children from low-income and low-educational background families.  相似文献   

National Vocational Qualifications: the candidates' experience     

Isaac S 《Health information and libraries journal》2007,24(1):50-57

PURPOSE: To examine the experience of studying for an National Vocational Qualification (NVQ) by past and present candidates in the library and information science sector, their reasons for choosing this qualification and its impact on completion. METHODOLOGY: Following a review of the literature, a number of NVQ candidates were interviewed using a semi-structured questionnaire. Candidates were contacted via e-mail through NVQ Centres and the LondonLinks e-mail list. There is a focus on health libraries as the flexibility and work-based nature of NVQs enable more staff to access training and education in this sector, despite the not uncommon low levels of staffing. RESULTS: NVQ Centres have gained experience since NVQs were launched 10 years ago. More support is offered to candidates and a number of issues such as isolation, are no longer a problem. An interesting result was the high number of candidates who had gone on to higher education following the completion of an NVQ. CONCLUSIONS: The NVQ is a useful method of providing staff with an opportunity to gain a recognized qualification. A significant number of candidates reported that the NVQ was ultimately a positive experience that improved their working practices. It can be an important first step for non-professional staff, but the future remains uncertain.  相似文献   

Implementation of a project-based molecular biology laboratory emphasizing protein structure-function relationships in a large introductory biology laboratory course     

Treacy DJ  Sankaran SM  Gordon-Messer S  Saly D  Miller R  Isaac SR  Kosinski-Collins MS 《CBE life sciences education》2011,10(1):18-24

In introductory laboratory courses, many universities are turning from traditional laboratories with predictable outcomes to inquiry-inspired, project-based laboratory curricula. In these labs, students are allowed to design at least some portion of their own experiment and interpret new, undiscovered data. We have redesigned the introductory biology laboratory course at Brandeis University into a semester-long project-based laboratory that emphasizes concepts and contains an element of scientific inquiry. In this laboratory, students perform a site-directed mutagenesis experiment on the gene encoding human γD crystallin, a human eye lens protein implicated in cataracts, and assess the stability of their newly created protein with respect to wild-type crystallin. This laboratory utilizes basic techniques in molecular biology to emphasize the importance of connections between DNA and protein. This project lab has helped engage students in their own learning, has improved students' skills in critical thinking and analysis, and has promoted interest in basic research in biology.  相似文献

THE COMMUNITY THEORY AND THE JEWISH SCHOOL CURRICULUM     

Dr. Isaac B. Berkson 《Journal of Jewish Education》2013,79(1):24-33

Almost no literature in the academic field of Jewish education exists that studies congregational rabbis as teachers of adults. This article seeks to contribute to filling the gap in the extant literature base. Using portraiture, the study describes and analyzes the aims of rabbinic teaching of adults in a synagogue setting. The findings suggest that regularly facilitating learners' intellectual and religious development, democratically guiding their communities' evolution through an emphasis on learning, and collaboratively joining their congregants in shaping the construction of personal and communal Jewish narratives are central aims of congregational rabbinic teaching of adults.  相似文献   

Plasma ß‐endorphin immunoreactivity: Response to resistance exercise     

Edgar F. Pierce  Norris W. Eastman  Hem T. Tripathi  Kirsten G. Olson  William L. Dewey 《Journal of sports sciences》2013,31(6):499-502

Previous research investigating the response of plasma ß‐endorphins (ß‐EP) to resistance exercise has resulted in equivocal findings. To further examine the effects of resistance exercise on ß‐endorphin immunoreactivity, six resistance‐trained athletes participated in a three‐set series of eight repetitions of isotonic exercise. All exercises were performed at 80% maximal effort. Blood was sampled from the group by venepuncture, both prior to and following the exercise bout, and ß‐endorphin concentration was determined by radioimmunoassay. The results indicated that mean ( ± S.E.) plasma levels of ß‐endorphins following exercise (18.04 ± 3.4 pg ß‐EP ml^‐1) were not significantly changed from pre‐exercise (control) levels (19.59 ± 2.4 pg ß‐EP ml^‐1), although there was considerable inter‐individual variability. Our results support previous research which has reported no significant changes in ß‐endorphin immunoreactivity following resistance exercise, as well as reported findings of considerable variability in the ß‐endorphin response to exercise.  相似文献
