Recently, interest in test subscore reporting for diagnosis purposes has been growing rapidly. The two simulation studies here examined factors (sample size, number of subscales, correlation between subscales, and three factors affecting subscore reliability: number of items per subscale, item parameter distribution, and data generating model)…

An identified barrier to the widespread adoption of universal socioemotional and behavioral screening in schools may be that existing instruments may be too burdensome or costly to administer. As a result, the County Schools Mental Health Coalition came together to develop a common assessment system, the Early Identification System (EIS). The…

The aim of this study is to develop an Entrepreneurship Scale to measure the entrepreneurial skills of 5th grade students and to conduct the reliability and validity of the scale. This research is a descriptive survey method. The pilot application was made with 432 students in Amasya City in Turkey. SPSS 23 and LISREL 8.80 programs were used to…

Linking score scales across different tests is considered speculative and fraught, even at the aggregate level (Feuer et al., 1999; Thissen, 2007). We introduce and illustrate validation methods for aggregate linkages, using the challenge of linking U.S. school district average test scores across states as a motivating example. We show that…

Spanish speakers in the United States are a steadily increasing population, up by 233% since 1980. Given the growing population of dual language learners (DLLs) and the large numbers of Spanish-speaking children enrolled in pre-kindergarten programs, addressing the educational needs of preschool-aged DLLs has become a national imperative.…

The purpose of this study is to develop a five-point Likert scale called 'Curriculum Fidelity'. For this purpose, a draft scale consisting of 65 items have been represented to the expert opinion firstly and it has been decided that 15 items should be excluded. The remaining 50 items have been given to 249 teachers and the maximum likelihood has…

This dissertation includes two independent research projects, one in astronomy education research and the other in planetary science/astrophysics research. In the first research effort, we investigate college students' conceptual and reasoning difficulties on the topic of planet formation pre-instruction. Through an analysis of over 1,000…

Inclusive postsecondary education (IPSE) programs can provide young adults with IDD opportunities for training and experiences in continuing academic instruction, transition goals, independent living as well as employment. Parent readiness is an important aspect of having young adults embrace their increasing independence. While the prospective…

This article discusses the theoretical and practical contributions of Zumbo, Gadermann, and Zeisser's family of ordinal reliability statistics. Implications, interpretation, recommendations, and practical applications regarding their ordinal measures, particularly ordinal alpha, are discussed. General misconceptions relating to this family of…

Tackling mathematics tasks often involves reading and interpreting different semiotic resources such as natural language (words), mathematical notation, and images. This study aims to enhance knowledge of how meaning relations, in the form of "cohesive ties" between and within different semiotic resources, are related to how difficult it…

Technological advancements initially made it possible for individuals with different cultures from different parts of the world to consider working together, and eventually collaboration turned into a necessity. Based on this necessity, OECD measured collaborative problem-solving (CPS) competencies of 15-year-old students from the countries…

The aim of this study was to determine the validity and reliability of the Nanotechnology Awareness Scale (NAI) in Turkish culture. The study group consists of 624 biology, physics and chemistry teachers working in secondary schools in Antalya, Denizli, Burdur and Ankara. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA)…

This research aims to produce feasible and valid assessment instrument of Higher Order Thinking Skill (HOTS) to measure students' Higher Order Thinking Skill in Physics learning. The type of this research was research and development, adapted from development model from Brog and Gall. The researchers modified Borg and Gall's development model as…

The impetus for test-based accountability systems is to improve the educational opportunities afforded to all students so as to improve their learning; therefore, integral to the validity argument of these systems is the appraisal of test-based inferences and decisions in terms of their consequences. Both positive and negative consequences of…

The Algerian English foreign language (EFL) baccalaureate is a high stake exam that assesses both students' learning and their critical thinking skills. Thus, devising appropriate and effective exam questions may be a problematic issue for tests designers. Under the requirements of the current Algerian English curriculum, the exam questions must…
