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.     

Automating Multiple Software Packages in Simulation Research for Structural Equation Modeling and Hierarchical Linear Modeling

Simulation researchers are sometimes faced with the need to use multiple statistical software packages in the process of conducting their research, potentially having to go between software packages manually. This can be a tedious and time-consuming process that generally motivates researchers to use fewer replications in their simulations than they might have used had the entire process been automated. This article describes a process by which multiple software packages can be used by governing the study with SAS and having SAS call DOS to run other software. Because this automation process should greatly reduce the time necessary for the simulations, it is hoped that this will enable researchers to use a greater number of replications and thereby enhance the precision and accuracy of their results.     

The effects of sex education on psychological counselling students in Turkey

Sex education is not included in Turkey’s national curriculum and is rarely referenced in school and university curricula. This is even true for those undertaking training in psychological counselling where the need may be great. Only a very few university schools of education offer an elective sex education course. A group of 64 guidance and psychological counselling students in ?stanbul Maltepe University was formed and provided with a 13-week sex education course. Before and after this course, the Sexual Attitudes Scale (SAS) was used for data collection using a semi-experimental design. Significant differences were detected between pretest and post-test SAS scores and on all SAS subscales. Results show that comprehensive sex education is effective in positively changing the sexual attitudes of PC students, challenging homophobic responses and displacing patriarchal attitudes. Based on these findings, the provision of sex education courses more generally in university schools of education is recommended, especially in conservative countries such as Turkey.

An SAS Macro for Implementing the Modified Bollen-Stine Bootstrap for Missing Data: Implementing the Bootstrap Using Existing Structural Equation Modeling Software

The Bollen-Stine bootstrap can be used to correct for standard error and fit statistic bias that occurs in structural equation modeling (SEM) applications due to nonnormal data. The purpose of this article is to demonstrate the use of a custom SAS macro program that can be used to implement the Bollen-Stine bootstrap with existing SEM software. Although this article focuses on missing data, the macro can be used with complete data sets as well. A series of heuristic analyses are presented, along with detailed programming instructions for each of the commercial SEM software packages.
