Future time perspective, like self-efficacy, can be understood both generally and domain specifically. Keeping this in mind, the current study aimed at developing and validating a Career Future Time Perspective Scale. In Study 1, we utilized an exploratory factor analysis and the Rasch rating model to ensure the construct validity of a Career…

Early childhood education and care (ECEC) remains a priority area for public policy, internationally and in Australia. However, an analysis of empirical research published internationally up to 2008 has identified a bias toward positivist methodologies within a "scientific/psychological' rather than educational perspective and with a focus on…

This article is a scale development study aimed at developing valid and reliable scales to understand English language teachers' knowledge about and attitudes towards plurilingualism and interculturalism. It is a descriptive survey model of quantitative research. During the scale development phase, literature review was conducted to develop the…

The third goal-achievement in the "Global Environment, Regions and Countries" unit of the 11 th grade geography curriculum includes the goal-behavior of "To be able to analyze the spreading areas of Turkish culture in terms of regional characteristics". In the geography curriculum rearranged by the Republic of Turkey Ministry…

In an effort to help improve classroom management, numerous researchers have examined students' social-emotional skills. Several studies have revealed that teachers indicate a need for a better understanding of their own social-emotional competencies (SEC) to effectively implement social-emotional learning (SEL) programs. However, very little is…

In this brief article, the reliability of scores for the Draw-A-Person Intellectual Ability Test for Children, Adolescents, and Adults (DAP: IQ; Reynolds & Hickman, 2004) was examined through several analyses with a sample of 147 children from rural Malawi, Africa using a Chichewa translation of instructions. Cronbach alpha coefficients for…

As a property of test scores, reliability/dependability constitutes an important psychometric consideration, and it underpins the validity of measurement results. A review of interpreter certification performance tests (ICPTs) reveals that (a) although reliability/dependability checking has been recognized as an important concern, its theoretical…

Many of the studies used to support the claim that student evaluations of teaching are reliable measures of teaching effectiveness have frequently calculated inappropriate reliability coefficients. This paper points to three coefficients that would be appropriate depending on if student evaluations were used for formative or summative purposes.…

Coefficient omega and alpha are both measures of the composite reliability for a set of items. Unlike coefficient alpha, coefficient omega remains unbiased with congeneric items with uncorrelated errors. Despite this ability, coefficient omega is not as widely used and cited in the literature as coefficient alpha. Reasons for coefficient omega's…

Many ways can be done to address the problem of students, one of them involving the students themselves (peer counselor). It required a standard model that can be applied by students as guidelines for the implementation of the guidance. Validity of the module it must be done according to the rules of various scientific tests. State University of…

The aim of this study is to identify and provide a clear idea about the helpful ways in determining the truth (or reliability) of arguments in the situations where it is necessary to make a decision. In this paper, we use systemic, structural-functional, activity approaches, methods of analysis, synthesis, moreover we discuss the works of…

This research was conducted to investigate 7th grade students' problem solving success rates on proportional reasoning problems and whether these success rates change with different problem types. 331 randomly selected students of grade seven participated in this study. A problem test which contains three different types of missing value (direct…

Educational research often requires mixing different research methodologies to strengthen findings, better contextualize or explain results, or minimize the weaknesses of a single method. This article provides practical guidelines on how to conduct such research in biology education, with a focus on mixed-methods research (MMR) that uses both…

The main points of Sijtsma and Green and Yang in Educational Measurement: Issues and Practice (34, 4) are that reliability, internal consistency, and unidimensionality are distinct and that Cronbach's alpha may be problematic. Neither of these assertions are at odds with Davenport, Davison, Liou, and Love in the same issue. However, many authors…

This book provides an overview and discussion of the evidence base of effective school inspections; reflecting on issues of validity and reliability of school inspections in relation to school effectiveness research, unintended consequences and emergent roles and responsibilities of Inspectorates of Education.
