Quantifying Error and Uncertainty Reductions in Scaling Functions: An ITEMS Module     

Tim Moses 《Educational Measurement》2014,33(2):29-40

This module describes and extends X‐to‐Y regression measures that have been proposed for use in the assessment of X‐to‐Y scaling and equating results. Measures are developed that are similar to those based on prediction error in regression analyses but that are directly suited to interests in scaling and equating evaluations. The regression and scaling function measures are compared in terms of their uncertainty reductions, error variances, and the contribution of true score and measurement error variances to the total error variances. The measures are also demonstrated as applied to an assessment of scaling results for a math test and a reading test. The results of these analyses illustrate the similarity of the regression and scaling measures for scaling situations when the tests have a correlation of at least .80, and also show the extent to which the measures can be adequate summaries of nonlinear regression and nonlinear scaling functions, and of heteroskedastic errors. After reading this module, readers will have a comprehensive understanding of the purposes, uses, and differences of regression and scaling functions.  相似文献   

Groundworks for a Pedagogy of Evolutionary Love Ethics: Archetypes of Moral Imagination in the Pragmatisms of Peirce and Addams          下载免费PDF全文

Russell G. Moses 《Educational theory》2017,67(6):713-725

In this essay, Russell G. Moses argues that Charles Sanders Peirce's article “Evolutionary Love” establishes a general normative framework for a logic of evolutionary, progressive imagination that can be used to elucidate an evolutionary continuity between the normative works of Jane Addams, John Dewey, and Alain Locke. This exercise contributes to an understanding of pragmatism as a philosophy that seizes insights from evolution in order to normatively reconstruct dynamic meanings of truth, reality, ethics, politics, and art. In a dynamic model of progressive evolution — one homologous to the Golden Rule of “love your neighbor” — we find a normative cosmology that animates the moral imagination of philosophy toward what Addams called “democracy and social ethics.” Moses concludes that in the Peircean model, together with subsequent developments, we may ultimately apprehend that evolution suggests a general form of development that may be hypothesized as a worthy normative guide for universal progressive education.  相似文献   

Representations of deaf characters in children's picture books     

Golos DB  Moses AM 《American annals of the deaf》2011,156(3):270-282

Picture books can influence how children perceive people of different backgrounds, including people with disabilities whose cultures differ from their own. Researchers have examined the portrayal of multicultural characters with disabilities in children's literature. However, few have specifically considered the portrayal of deaf characters, despite increased inclusion of deaf characters in children's literature over the past two decades. The present study analyzed the portrayal of deaf characters in picture books for children ages 4-8 years. A content analysis of 20 children's picture books was conducted in which the books were analyzed for messages linked to pathological and cultural categories. Results indicated that these books did not portray Deaf characters from a cultural perspective but, rather, highlighted aspects of deafness as a medical condition, one that requires fixing and that perpetuates stereotypes of deafness as a disability.  相似文献   

A Comparison of IRT Proficiency Estimation Methods Under Adaptive Multistage Testing          下载免费PDF全文

Sooyeon Kim  Tim Moses  Hanwook Yoo 《Journal of Educational Measurement》2015,52(1):70-79

This inquiry is an investigation of item response theory (IRT) proficiency estimators’ accuracy under multistage testing (MST). We chose a two‐stage MST design that includes four modules (one at Stage 1, three at Stage 2) and three difficulty paths (low, middle, high). We assembled various two‐stage MST panels (i.e., forms) by manipulating two assembly conditions in each module, such as difficulty level and module length. For each panel, we investigated the accuracy of examinees’ proficiency levels derived from seven IRT proficiency estimators. The choice of Bayesian (prior) versus non‐Bayesian (no prior) estimators was of more practical significance than the choice of number‐correct versus item‐pattern scoring estimators. The Bayesian estimators were slightly more efficient than the non‐Bayesian estimators, resulting in smaller overall error. Possible score changes caused by the use of different proficiency estimators would be nonnegligible, particularly for low‐ and high‐performing examinees.  相似文献   

Randomized impact evaluation of education interventions: experiences and lessons from a reading to learn intervention in East Africa

This paper presents the experiences and lessons learnt during the design and implementation of the randomized impact evaluation (IE) of a reading to learn (RtL) intervention in early primary grades. The study was to assess the impact of RtL on literacy and numeracy among pupils in low-performing districts in East Africa. The intervention was designed in a way that in each country one district implemented an intervention package that included teacher training, and teaching and learning materials; while the other district implemented this same package with an additional parental involvement component. Baseline data were collected in mid-2009 in Grades 1 and 2, and in 2010 for the incoming Grade 1. The endline data were collected in mid-2011. A total of 119 treatments and 110 control schools participated in the study. The randomized design provided an opportunity to attribute causality and also qualitatively establish pathways through which the intervention impacted on learning. The paper provides lessons learnt and demonstrates how the challenges faced during the evaluation were addressed. Additionally, the paper shows how IE was utilized to provide robust evidence of what works thus enabling policy-makers to make decisions on sustainability and scale-up of education interventions.  相似文献

Effects of traditional and discovery instructional approaches on learning outcomes for learners of different intellectual development: A study of chemistry students in Zambia     

Moses M. Mulopo  H. Seymour Fowler 《科学教学研究杂志》1987,24(3):217-227

This study examined the differential effectiveness of traditional and discovery methods of instruction for the teaching of science concepts, understandings about science, and scientific attitudes, to learners at the concrete and formal level of cognitive development. The dependent variables were achievement, understanding science, and scientific attitude; assessed through the use of the ACS Achievement Test (high school chemistry, Form 1979), the Test on Understanding Science (Form W), and the Test on Scientific Attitude, respectively. Mode of instruction and cognitive development were the independent variables. Subjects were 120 Form IV (11th grade) males enrolled in chemistry classes in Lusaka, Zambia. Sixty of these were concrete reasoners (mean age = 18.23) randomly selected from one of the two schools. The remaining 60 subjects were formal reasoners (mean age 18.06) randomly selected from a second boys' school. Each of these two groups was randomly split into two subgroups with 30 subjects. Traditional and discovery approaches were randomly assigned to the two subgroups of concrete reasoners and to the two subgroups of formal reasoners. Prior to instruction, the subjects were pretested using the ACS Achievement Test, the Test on Understanding Science, and the Test on Scientific Attitude. Subjects received instruction covering eight chemistry topics during approximately 10 weeks. Posttests followed using the same standard tests. Two-way analysis of covariance, with pretest scores serving as covariates was used and 0.05 level of significant was accepted. Tukey WSD technique was used as a follow-up test where applicable. It was found that (1) for the formal reasoners, the discovery group earned significantly higher understanding science scores than the traditional group. For the concrete reasoners mode of instruction did not make a difference; (2) overall, formal reasoners earned significantly higher achievement scores than concrete reasoners; (3) in general, subjects taught by the discovery approach earned significantly higher scientific attitude scores than those taught by the traditional approach. The traditional group outperformed the discovery group in achievement scores. It was concluded that the traditional approach might be an efficient instructional mode for the teaching of scientific facts and principles to high school students, while the discovery approach seemed to be more suitable for teaching scientific attitudes and for promoting understanding about science and scientists among formal operational learners.  相似文献   

Teaching,research and scholarship in different disciplines   总被引：2，自引：0，他引：2  

Ingrid Moses 《Higher Education》1990,19(3):351-375

Teaching and research are the primary functions of academics in all academic disciplines in all Australian universities. Scholarship is expected of all academics whether in the university or college sector. Under a new policy Australian higher education institutions have to develop educational profiles that will describe their strengths in teaching and research. The federal government, and indeed, institutions, are developing and using performance indicators to distribute resources. Some of these, e.g. number of publications, number of research grants, and number of Ph.D. graduates are disadvantaging the Humanities. This paper addresses differences in four disciplines, Chemistry, Engineering, English and Law as they are described by other researchers and emerge from a questionnaire study at an Australian university.  相似文献

An approach to assessing and facilitating causal language in adults with learning disabilities based on Piagetian theory     

N Moses  H B Klein  E Altman 《Journal of learning disabilities》1990,23(4):220-228

Salient characteristics associated with Piagetian cognitive stages served as the basis for developing a linguistic taxonomy of causal semantic relations. Causal statements from adults with learning disabilities and normally achieving adults were analyzed and organized within this taxonomy. A relationship between Piagetian cognitive stages and verbal expressions of causality was identified. Based on this relationship, principles of Piagetian cognitive theory were used to design assessment and intervention plans for adults with learning disabilities.  相似文献
