The importance of measuring growth in response to intervention models: Testing a core assumption     

Schatschneider C  Wagner RK  Crawford EC 《Learning and individual differences》2008,18(3):308-315

A core assumption of response to instruction or intervention (RTI) models is the importance of measuring growth in achievement over time in response to effective instruction or intervention. Many RTI models actively monitor growth for identifying individuals who need different levels of intervention. A large-scale (N=23,438), two-year longitudinal study of first grade children was carried out to compare the predictive validity of measures of achievement status, growth in achievement, and their combination for predicting future reading achievement. The results indicate that under typical conditions, measures of growth do not make a contribution to prediction that is independent of measures of achievement status. These results question the validity of a core assumption of RTI models.  相似文献

The problem of distinguishing particular sounds, such as conversation, against a background of irrelevant noise is a matter of common experience. Psychologists have studied it for some 40 years, but is is only comparatively recently that computer modelling of the phenomenon has been attempted. This article reviews progress made, possible practical applications, and prospects for the future.  相似文献   

Supporting prospective teachers' conceptions of modelling in science     

Barbara A. Crawford  Michael J. Cullin 《International Journal of Science Education》2013,35(11):1379-1401

This study investigated prospective secondary science teachers' understandings of and intentions to teach about scientific modelling in the context of a model‐based instructional module. Qualitative methods were used to explore the influence of instruction using dynamic computer modelling. Participants included 14 secondary science prospective teachers in the USA. Research questions included: (1) What do prospective teachers understand about models and modelling in science? (2) How do their understandings change, following building and testing dynamic computer models? and (3) What are prospective teachers' intentions to teach about scientific models? Scaffolds in the software, Model‐IT, enabled participants to easily build dynamic models. Findings related to the process, content, and epistemological aspects of modelling, including: (a) prospective teachers became more articulate with the language of modelling; and (b) the module enabled prospective teachers to think critically about aspects of modelling. Still, teachers did not appear to achieve full understanding of scientific modelling.  相似文献

Responding to university policies and initiatives: the role of reflexivity in the mid-career academic   总被引：1，自引：0，他引：1  

Angela Brew  David Boud  Lisa Lucas  Karin Crawford 《Journal of Higher Education Policy & Management》2017,39(4):378-389

How do academics make sense of university policies and strategic initiatives and act on them? Interviews were conducted with 27 mid-career academics in different disciplines, different research-intensive university environments and two countries (England and Australia). Data were analysed iteratively utilising a critical realist perspective, specifically, Archer’s modes of reflexivity. The paper argues that individuals’ responses to university policies and initiatives, to changes in policy and policy conflicts, can at least partially be understood through interrogating the modes of reflexivity they employ.  相似文献   

How do pre-kindergarteners spend their time? Gender,ethnicity, and income as predictors of experiences in pre-kindergarten classrooms   总被引：2，自引：0，他引：2

The current paper considers how children spend their time in state-funded pre-kindergarten programs and how time use relates to ethnicity, gender, and family income, based on the assumption that how time is spent in pre-kindergarten is relevant for the programs’ success in narrowing achievement gaps. Classroom observations of 2061 children in 652 pre-k programs in 11 states were analyzed. Findings indicated that the pre-kindergarten day was roughly equally divided among free choice, teacher-assigned activities, and meals/routines. Children spent much of their time in language/literacy, social studies, and art, and less time in math and gross motor activities. Much of the pre-k day was spent in ‘no coded learning activity.’ Children in classes with lower proportions of Latino and African American children and higher average income-to-need ratios were generally engaged in richer and more stimulating experiences. The child-level variables of ethnicity and income were generally unrelated to how children spent their time, above and beyond the effects of classroom-level ethnicity and income. There were generally small, but significant gender differences – always in the gender-stereotyped direction – in how time was spent, especially during free choice time.  相似文献   

Are parental concerns about children's inactivity warranted, and are they associated with a supportive home environment?     

Jackson M  Crawford D  Campbell K  Salmon J 《Research quarterly for exercise and sport》2008,79(3):274-282

This paper explores parental concern about children's activity levels and whether parents who are concerned about their child's activity provide a supportive environment. A sample of 615 parents of 5-6-year-old children and 947 parents of 10-12-year-old children completed a questionnaire. Just over 50% of parents reported they were concerned their child was not getting enough activity. Children of concerned parents were less active than those whose parents were not concerned. These findings suggest that parents who are concerned about their child's physical activity levels provided a less supportive environment for physical activity than parents who are not concerned. The challenge for public health will be to harness parental concerns and translate them into action.  相似文献
