The objective of this project was to develop a multiple choice test of graphing skills appropriate for science students from grades seven through twelve. Skills associated with the construction and interpretation of line graphs were delineated, and nine objectives encompassing these skills were developed. Twenty-six items were then constructed to measure these objectives. To establish content validity, items and objectives were submitted to a panel of reviewers. The experts agreed over 94% of the time on assignment of items to objectives and 98% on the scoring of items. TOGS was first administered to 119 7th, 9th, and 11th graders. The reliability (KR-20) was 0.81. Poorly functioning items were rewritten based on the item difficulty and discrimination data. The revised version of the test was given to 377 7th through 12th grade students. Total scores ranged from 2 to 26 correct (X = 13.3, S.D. = 5.3). The reliability (KR-20) was 0.83 for all subjects and ranged from 0.71 for eighth graders to 0.88 for ninth graders. Point biserial correlations showed 24 of the 26 items above 0.30 with an average value of 0.43. It was concluded from this and other data that TOGS was a valid and reliable instrument for measuring graphing abilities.  相似文献

Many states are implementing response‐to‐intervention (RTI)–based assessment as the sole means of identifying students with specific learning disabilities (SLDs). Although RTI is often hailed as an improved model of identification, concern for the possibility of this model elevating false positives has been examined. The risk of RTI producing a second form of diagnostic error, however, has received relatively little attention, namely, false negatives. The widespread implementation of RTI necessitates an analysis of its ability to identify students who are most vulnerable to be inaccurately judged as responsive to instruction, namely, students with coexisting intellectual talent and SLDs.  相似文献

In recent years, Australian films have failed to capture the public’s attention at the Australian box office. Why? Do Australians have an aversion to their own films? Or does the release strategy—advertising/publicity expenditure and opening number of screens—explain the lacklustre performance? We find that even though Australian films are generally advertised more heavily and released more widely than non-Australian films, ceteris paribus, they earn less at the box office. We also analyse a subsample of our data for which Film Finance Corporation funding information is available and find that government subsidies have no impact on a film’s financial success at the box office.  相似文献

Following Scott (this issue), this paper examines how environmental education researchers might intervene to greater effect in the policies and practices of our governments and local and international organizations through individual and collective programmes of research. Suggesting that public scholarship or academic activism can engage a wide spectrum of genres and outcomes of research activity, the paper proposes that what stands out are not the methods employed in seeking to have research ‘be of use’, but instead what can be termed modes of engagement. These can be described as including interpretive critique or ‘speaking truth to power’, public space and collaboration, and the role of research imagination in social life. These three modes are discussed with the hope that researchers will consider their possibilities and implications in working towards more powerful public scholarship in environmental education.  相似文献
