Textbook treatments and students' understanding of acceleration

A single science textbook often provides the syllabus for courses at upper secondary and tertiary levels, and may be used as a principal source of information or explanation. The research reported in this article challenges such practices. The ways in which the concept, acceleration, is treated in physics textbooks is compared with understandings of the concept demonstrated by final-year secondary (Year 12) and first-year university students. Some students' understandings are shown to be incomplete in ways that parallel misleading or inaccurate textbook treatments of the concept. In addition to misleading or inaccurate statements, the limitations of some textbook treatments of acceleration were found to include: lack of attempts to make explicit relationships with other concepts, failure to point out when it is appropriate to use particular definitions or that an alternative definition might be more appropriate in specific situations, inclusion of operational definitions without conceptual explanations, and a focus on quantitative treatments while overlooking the development of qualitative understanding. Two principal aspects that distinguished the ways in which the students understood acceleration were identified: (a) the relation between acceleration and velocity; and (b) the relation between acceleration and force(s). The results of the study have implications for teaching and, in particular, for the use of textbooks in teaching. These implications are discussed in the article.  相似文献   

Consulting Parents to Improve a Child Guidance Service     

Judith Hodgson  Sheila Mattison  Ellie Phillips  Gloria Pollack 《Educational Psychology in Practice》2001,17(3):263-272

This paper describes a study undertaken with a group of parents whose children had been referred to the Knowsley Child Guidance Service. A qualitative methodology was used to analyse in-depth interviews with parents. The results led to practical recommendations for the improvement of service delivery. These recommendations had implications for schools and other services involved with parents/carers and children. The survey also provided a base from which to develop a questionnaire for the continuing evaluation of good practice within the child guidance service.  相似文献   

Inaccuracy as a privacy-enhancing tool     

Gloria González Fuster 《Ethics and Information Technology》2010,12(1):87-95

The accuracy principle is one of the key standards of informational privacy. It epitomises the obligation for those processing personal data to keep their records accurate and up-to-date, with the aim of protecting individuals from unfair decisions. Currently, however, different practices being put in place in order to enhance the protection of individuals appear to deliberately rely on the use of ‘inaccurate’ personal information. This article explores such practices and tries to assess their potential for privacy protection, giving particular attention to their legal implications and to related ethical issues. Ultimately, it suggests that the use of ‘inaccurate’ data can potentially play a useful role to preserve the informational autonomy of the individual, and that any understandings of privacy or personal data protection that would tend to unduly limit such potential should be critically questioned.  相似文献

Female farmers and the social construction of access to agricultural information     

Gloria J. Leckie 《Library & information science research》1996,18(4):297-321

This article examines the ways in which the transfer of information about farming practice is gendered, and how the gendering of access to agricultural information affects the social realities of farming women. The research focuses on a sample of Ontario female farmers who were interviewed extensively about their farming practices, including the ways in which they sought and found information to help them further their farming knowledge. It was found that female farmers utilized both formal and informal channels of information, but that these channels were not readily nor easily accessible to female farmers. Attempts to extract needed information resulted in the manifestation of issues regarding social and professional legitimacy. Female farmers must, therefore, devise alternate strategies and networks for information gathering. The study demonstrates that information acquisition in farming is a socially mediated process which reflects the socially constructed gender relations of agriculture itself.  相似文献

Reading development in an orthographically regular language: effects of length, frequency, lexicality and global processing ability     

Pierluigi Zoccolotti  Maria De Luca  Gloria Di Filippo  Anna Judica  Marialuisa Martelli 《Reading and writing》2009,22(9):1053-1079

The acquisition of reading skill was studied in 503 Italian children in first to eighth grade using a task that required reading of lists of words and non-words. Analysis of the metric characteristics of the measures indicated that reading speed but not accuracy was normally distributed across all ages considered. The role of specific effects (length, word frequency, and lexicality) versus global factors in reading speed was examined using the Rate–Amount Model (RAM). A global processing factor accounted for a large portion of the variance. Specific influences of length, frequency, and lexicality were detected in different periods of development over and above the global processing factor. Length modulated performance at early stages of learning and progressively less later on; in the case of non-words, the effect of length was large but did not change as a function of grade. The lexicality effect, present at all ages for high frequency words and by third grade for low frequency words increased with reading practice indicating a progressive differentiation in the ability to read words and non-words. Finally, the effect of word frequency was highest in third grade and then decreased. These findings are discussed in terms of their relevance for reading acquisition in a language with transparent orthography and their implications for evaluating developmental reading deficits. Overall, it is proposed that RAM is a useful tool for disentangling the role of specific versus global factors in reading development.  相似文献

Morphological awareness in Spanish-speaking English language learners: within and cross-language effects on word reading     

Gloria Ramirez  Xi Chen  Esther Geva  Heidi Kiefer 《Reading and writing》2010,23(3-4):337-358

This study investigated within and cross-language effects of morphological awareness on word reading among Spanish-speaking children who were English Language Learners. Participants were 97 Spanish-speaking children in grade 4 and grade 7. Morphological awareness in Spanish and in English was evaluated with two measures of derivational morphology. The results showed that Spanish morphological awareness contributed unique variance to Spanish word reading after controlling for other reading related variables. English morphological awareness also explained unique variance in English word reading. Cross-linguistic transfer of morphological awareness was observed from Spanish to English, but not from English to Spanish. These results suggest that morphological awareness is important for word reading in Spanish, a shallow orthography with a complex morphological system. They also suggest that morphological awareness developed in children’s L1 is associated with word reading in English, their L2.  相似文献   

Comparison of Hydrostatic Weighing at Residual Volume and Total Lung Capacity in Children

Abstract

The influence of perceptions of the motivational climate and perceived ability on situational motivation and the physical activity behavior of 213 male and 229 female adolescent physical education students (M age= 12.56 years; SD = 0.96) was examined over a 3-day period. A significant age by gender interaction emerged, with physical activity declining from the sixth to eighth grade. The decline was more pronounced among female than male students. Perceptions of a mastery climate were strongly related to more self-determined forms of situational motivation. In contrast, perceptions of a performance climate were strongly related to less self-determined forms of situational motivation. Results of a hierarchical regression analysis revealed gender, perceived ability, and perceptions of a mastery climate to explain a significant amount of variance in physical activity. These findings suggest that promoting a mastery oriented motivational climate in physical education will foster self-determined situational motivation and physical activity.  相似文献
