Rasch analysis for psychometric improvement of science attitude rating scales

ABSTRACT

Students’ attitude towards science (SAS) is often a subject of investigation in science education research. Survey of rating scale is commonly used in the study of SAS. The present study illustrates how Rasch analysis can be used to provide psychometric information of SAS rating scales. The analyses were conducted on a 20-item SAS scale used in an existing dataset of The Trends in International Mathematics and Science Study (TIMSS) (2011). Data of all the eight-grade participants from Hong Kong and Singapore (N?=?9942) were retrieved for analyses. Additional insights from Rasch analysis that are not commonly available from conventional test and item analyses were discussed, such as invariance measurement of SAS, unidimensionality of SAS construct, optimum utilization of SAS rating categories, and item difficulty hierarchy in the SAS scale. Recommendations on how TIMSS items on the measurement of SAS can be better designed were discussed. The study also highlights the importance of using Rasch estimates for statistical parametric tests (e.g. ANOVA, t-test) that are common in science education research for group comparisons.     

Teachers learning from analysis of other teachers' reading lessons

This study explores teachers' responses to a video-based multimedia program designed to reflect current views of effective professional development for practicing teachers. The Case Studies of Reading Lessons program engages teachers in analysis of others' reading instruction. Findings showed teachers' enthusiasm for studying authentic reading instruction but suggest mixed views of the benefits of questions used to guide analysis of instruction. Teachers reported making connections to their own reading instruction and provided evidence that analysis of reading lessons may contribute to reflective practice. Future studies might investigate long-term effects of systematic analysis of case studies to develop adaptive expertise.     

The McCarthy scales of children's abilities as a predictor of reading readiness and reading achievement

The purpose of the present study was to determine if the McCarthy Scales of Children's Abilities could be utilized as a predictor of reading readiness and reading achievement. Thirty-three kindergarten children were tested with the McCarthy Scales and subsequently examined with the MacMillan Reading Readiness Test and the Metropolitan Achievement Test. A correlational analysis of data resulted in significant relationships between McCarthy General Cognitive Indexes, Quantitative, and Perceptual-Performance Scales and both the MacMillan and Metropolitan Tests. Based upon these correlations, it was hypothesized that, for this sample of children, visual discrimination and sequential ability skills may have been crucial factors in reading readiness and reading achievement, rather than verbal abilities.     

The kindergarten auditory screening test as a predictor of reading disability

Correlation coefficients were obtained between the Kindergarten Auditory Screening Test (KAST), the Metropolitan Readiness Test (MRT), and the Gates MacGinitie Reading Tests, Primary Form (GMRT). The KAST and MRT were given to kindergartners near the end of the spring semester and the GMRT to these same children in first grade during February of the following year. Neither the coefficients obtained nor an examination of extreme groups indicated that the KAST was an effective predictor of reading disability.

Secondary school physics teachers' conceptions of scientific evidence: An exploratory case study

This article describes an exploratory case study of secondary school physics teachers' conceptions of scientific evidence. The nature of teachers' conceptions of evidence was derived from an analysis of data collected from 1 preservice and 2 in‐service teachers. Each teacher responded to a series of research prompts in multiple interviews and handwritten tasks. In these research prompts, the teachers thought aloud while designing experiments and critically evaluating student‐collected data as presented in hypothetical classroom scenarios. Spoken and written data were recorded. The data set was coded and analyzed using standard qualitative analysis techniques. Data from this study suggest that, while contemplating the reliability and validity of hypothetical student‐generated scientific evidence, the teachers frequently intertwined conceptions of evidence with subject matter concepts centrally relevant to the hypothetical investigation. Data also indicate that the relationship between subject matter knowledge and conceptions of evidence was more pronounced for some conceptions of evidence than for others. Results suggest that a fuller study is warranted. Suggestions for future research include exploring such relationships in other physics content areas as well as other scientific disciplines. Implications for science teacher education suggest that science and science methods courses should encourage preservice teachers to engage in original scientific research, as well as participate in peer review and critique. © 2003 Wiley Periodicals, Inc.

Building disciplinary literacy: an analysis of history,science and math teachers' close reading strategies

This collective case study explores the strategies history, science and math teachers use to conduct close readings in their disciplines. Through qualitative analysis of forum posts and lesson plans submitted to a Massive Open Online Course (MOOC) designed as professional development (PD), this study examines the strategies history, science and math teachers reported using to conduct close readings in their discipline, as well as how these teachers conduct close readings after receiving professional development on reading strategies for their disciplines. Ultimately, the research showed that while more teachers reported using disciplinary literacy strategies following the PD, they did not necessarily report using the strategies that, according to experts in their fields, are considered to be the most important for their discipline.     

The appropriateness of the NC state-mandated reading competency test for deaf students as a criterion for high school graduation

Deaf students consistently score lower on standardized measures of reading comprehension than their hearing peers. Most of the studies that have been conducted to explain this phenomenon have focused on variables within the reader, and important differences have been found between deaf and hearing readers. More recently, in the face of increasingly high-stakes consequences, researchers are looking "outside" the reader, at the tests themselves, to determine whether there are fairness issues for special populations, such as deaf students. The study reported here, the first of its kind with deaf students, examines the North Carolina (NC) reading comprehension test. The study employs the same method used originally by NC to determine its appropriateness of the test for the general population of NC students. The experts in this article, like those in the original construction of the NC test, are familiar with the content of the reading curriculum in NC; however, the raters in this article bring a special perspective related to teaching and testing reading of students who are deaf. Findings from this study raise questions about the appropriateness of the NC reading test for deaf students. Implications for future research and instructional practice are discussed.

Peer assessment as a learning tool for enhancing student teachers' preparation

This study investigates how peer assessment contributes to enhancing student teachers' preparation during field experience. A semi-structured interview was conducted with 72 student teachers. The findings showed that the student teachers have positive beliefs about peer assessment. They think that it can be beneficial if some changes are made in the way it is employed in teacher education programs. In light of the study findings, the researchers put forth a number of suggestions and recommendations for employing peer assessment in teacher education programs in Jordan.     

Pre-service teachers' reasons for choosing teaching as a career in Singapore

As the national teacher education institute in Singapore, the National Institute of Education (NIE) prepares all teachers seeking to be employed within the education service in Singapore. In the last decade, NIE's enrolment for initial teacher preparation programmes has grown significantly, with peaks in numbers during the recession years. There is also some evidence of attrition when beginning teachers complete their 3-year bond with the Ministry of Education, which sponsors their teacher education programme. It is thus important to determine empirically the reasons why pre-service teachers join the teaching profession, to see whether this can inform us about measures that can be taken to ensure they stay on in the profession. As part of a longitudinal study on beginning teachers' attitudes towards teaching and professional development, a research survey, the first of three data collections, was administered to whole cohorts of pre-service teachers entering NIE's three main teacher preparation programmes in July 2004. This paper presents the survey findings on pre-service teachers' reasons for choosing teaching as a career and discusses the differences between cohorts of different programmes. The implications of the study are discussed in terms of informing future policy and practice in the areas of teacher recruitment, retention and professional development.     

Background factors and preschool test scores as predictors of reading: a nine-year longitudinal study

Approximately 400 children were first tested at 4, and background factors were ascertained at that time. Further testing included a kindergarten reading readiness test and reading tests at grades 3 and 8. The best preschool predictors of reading were naming tests for boys, and general verbal ability for girls. At the kindergarten level a quantitative test surpassed tests of phonemic awareness and language in predicting reading, for both boys and girls. Family history of learning disability and preschool test behavior contributed to prediction of reading. Effects of birth order were strongest at the preschool level, and handedness had its only effects at that level. Relationships of some factors to reading differed by gender. Socioeconomic status had significant effects only for boys, and a speech delay only for girls. Conclusions were that some background factors may contribute to the preschool prediction of reading, and particularly to the prospective identification of poor readers.
