IS IT WORTH USING CAS FOR SYMBOLIC ALGEBRA MANIPULATION IN THE MIDDLE SECONDARY YEARS? SOME TEACHERS’ VIEWS     

Robyn Pierce  Lynda Ball  Kaye Stacey 《International Journal of Science and Mathematics Education》2009,7(6):1149-1172

The use of Computer Algebra Systems (CAS) in years 9 and 10 classrooms as a tool to support learning or in preparation for senior secondary mathematics is controversial. This paper presents an analysis of the positive and negative aspects of using CAS identified in the literature related to these year levels, along with the perceptions of 12 experienced secondary teachers who were working with years 9 and 10 students. The literature review shows that CAS is valued for calculation and manipulation capabilities, the option of alternative representations, the opportunity for systematic exploration and for prompting rich discussion. However, the technical overhead, initial workload for the teacher and unresolved questions about the perceived relative contribution of machine and by-hand work to learning currently pose obstacles to teaching with CAS in the middle secondary years. The teachers who contributed data to this study perceived that using CAS in their teaching is, on balance, worth the effort. However, they believed that CAS is of most benefit to their high ability students and may present an obstacle to their low ability students’ learning of mathematics.  相似文献   

The effectiveness of multimedia programmes in children's vocabulary learning     

Joana Acha 《British journal of educational technology : journal of the Council for Educational Technology》2009,40(1):23-31

The present experiment investigated the effect of three different presentation modes in children's vocabulary learning with a self-guided multimedia programmes. Participants were 135 third and fourth grade children who read a short English language story presented by a computer programme. For 12 key (previously unknown) words in the story, children received verbal annotations (written translation), visual annotations (picture representing the word), or both. Recall of word translations was better for children who only received verbal annotations than for children who received simultaneously visual and verbal annotations or visual annotations only. Results support previous research about cognitive load in e-learning environments, and show that children's learning processes are hindered by limited working memory. This finding implies a challenge for multimedia programmes designed for children and based on self-regulated learning.  相似文献   

Age Differences in Children's Ability to Model Motor Behavior     

Jerry R. Thomas  Caryl Pierce  Susan Ridsdale 《Research quarterly for exercise and sport》2013,84(3):592-597

Abstract

In order to investigate the effects of modeling behavior for seven- and nine-year-old children, 30 seven-year-old and 30 nine-year-old females were randomly assigned within age level to three groups. These groups differed according to whether a model was presented at the beginning, midway, or not at all during 12 trials on the stabilometer. Both age groups were found to be similar in performance in the no model condition and, for both age groups, the beginning model condition was found to facilitate performance. However, the introduction of the model after six trials had a detrimental effect on the performance of younger children but facilitated older children's performance. These findings were interpreted in light of a likely increase in the processing capacity of nine year olds as well as an increase in the number of movement schemes that were previously stored in the older girls.  相似文献   

Advancing Critical Thinking and Information Literacy Skills in First Year College Students     

Mark Alfino  Michele Pajer  Linda Pierce  Kelly O'Brien Jenks 《College & Undergraduate Libraries》2013,20(1-2):81-98

ABSTRACT

This article provides a case study of recent curriculum development in a freshman skills program which integrates critical thinking and English composition as linked courses at Gonzaga University. Known as “thought and expression” courses, this block of courses, which also includes speech communication, can be taken by students separately or in a linked cohort with the same twenty students in each class. In linked courses, faculty are generally aware of each others' course topics and assignments, and they meet to discuss student progress and look for opportunities for curriculum integration. In this case study, library faculty were included in the instructional team, and information literacy skills that relate to critical thinking were integrated into the goals of the critical thinking and English composition courses. Faculty involved in the courses believe that integrating library skills into course goals adds coherence to the curriculum; it also helps students to achieve the developmental goals of the learning community created by this course model.  相似文献   

Predicting child outcomes from preschool quality in Portugal     

Isabel M. P. Abreu-Lima  Teresa B. Leal  Joana Cadima  Ana Madalena Gamelas 《European Journal of Psychology of Education - EJPE》2013,28(2):399-420

The main purpose of this study is to analyze whether quality of preschool classrooms relates to 4- and 5-year-old children developmental outcomes. The study was conducted in 60 classrooms in Porto Metropolitan Area, Portugal. Children (N?=?215) were evaluated in the literacy, math, and behavior domains. Preschool quality was assessed through classroom observations using the ECERS-R and the Early Language and Literacy Classroom Observation. Global classroom quality although relatively low, predicted children’s literacy skills and behavior but not math skills. Quality of language and literacy environment was not consistently related to child outcomes. Mother educational level stood out as consistently predicting most of child developmental outcomes. The relevance of these results is discussed considering the Portuguese educational scenario, in the realm of an international context.  相似文献   

The Private School Takeover     

Dr. Walter D. Pierce  Dr. Dorothy Franks 《Clearing house (Menasha, Wis.)》2013,86(9):389-393

In addition to teaching subject matter, I feel students need to learn from someone they can perhaps look up to. They must learn that certain things are valued and important in society. These things are simple manners; compassion for others; how to make moral and responsible choices; and to take responsibility. At this level they need guidance. Maybe someone at home is not demanding civility; maybe they are and are just as frustrated as we. But it must be clear that certain standards must be adhered to. Certain types of behavior are requisite!.  相似文献   

Visualizing diversity: the Oregon Health & Science University Educational Use Photo Diversity Repository     

Pamela Pierce  Linda Felver 《Journal of the Medical Library Association》2021,109(3):472

Background:Health science education needs images that represent both the diversity of patients served and the diversity of its students and clinicians. To begin to address this need, a nurse educator and librarian collaborated to launch the Oregon Health & Science University (OHSU) Educational Use Photo Diversity Repository. This online resource provides educators of health professional students with access to photos of pathophysiological conditions in skin of various colors so their students can increase their awareness of issues related to health and diversity and prepare themselves for more effective clinical work with their future patients.Case Presentation:The OHSU Educational Use Photo Diversity Repository became a university-wide project, leveraging the thoughts of an image advisory board, clinicians, faculty members, administrators, and students. Key considerations were given to the workflows used to submit photos as well as the controlled vocabulary for submitting images. The repository was started with photos already in existence, with future plans to have images taken specifically for the repository.Conclusions:This repository is playing an important role as OHSU and the health sciences in general reflect on the role of systemic racism in health care and clinical education. Negotiating issues of consent, patient health information, and privacy around using different technologies to take photos is a complex and ongoing process. The repository provides opportunities for closely examining these processes and creating improvements that result in more equitable education.  相似文献   

Programmatic Risk-Taking by American Opera Companies     

J. Lamar Pierce 《Journal of Cultural Economics》2000,24(1):45-63

This study explores the relationships between culture,politics, and the decision-making process of theAmerican opera company. It combines socio-economicdata with the financial and program data of key operacompanies to explore important influences inprogramming decisions. It tests the hypothesizedrelationships between risk-taking by opera companiesand socio-economic variables such as wealth,government funding, and donor involvement. This studyfinds that local government funding encourages programconventionality, while federal support such as the NEAencourages program risk-taking. Socio-economicvariables such as conservatism, wealth, and educationlevel were also found to affect opera programming.  相似文献   

Financial returns,price determinants,and genre effects in American art investment   总被引：1，自引：1，他引：0  

Richard J. Agnello  Renée K. Pierce 《Journal of Cultural Economics》1996,20(4):359-383

Past studies on art investment generally have found that returns are low and risk is high. In this study we find that the return to art investment is more in line with traditional investments and thus the cost for consumption associated with art seems fairly small. Employing a large sample of paintings by 66 American artists sold at auction between 1971–1992, average returns are found to be over 9 per cent and 3 per cent in nominal and real terms, respectively. The model employs a log linear price regression estimated by pooled cross section and time series data, and allows rates of return as well as hedonic values for various painting and auction attributes to be estimated. These include size, media, age of execution, authenticity of the work, and auction month and house. In addition, rates of return are differentiated by artist, time period of investment, price range and genre of the painting. The findings indicate significant sensitivity of rates of return to these data stratifications.This paper was presented at the 9th international conference of the Association for Cultural Economics, held in Boston, May 8–11, 1996.  相似文献
