No matter how strong the theoretical infrastructure of a study is, if the measurement instruments do not have the necessary psychometric qualities, there will be a question of trust in interpreting the findings, and it will be inevitable to make wrong decisions with the results. One of the important steps in scale development/adaptation studies is…

This study's purposes were to develop a rating scale for midlevel band performance and validate a theoretical structure for the scale. Research questions were (a) What qualities describe excellent seventh- and eighth-grade band performance? (b) What items constitute a Midlevel Band Performance Rating Scale (MBPRS)? (c) How reliable is the MBPRS?…

This investigation (1) elucidates genuine interest in the context of learning from Dewey's perspective, (2) assesses construct validity evidence for a genuine interest conceptual model using data from the Factors Effecting Ethics Learning survey, and (3) assesses measurement invariance of the genuine interest constructs between male (n = 352) and…

Independent school leaders are continually faced with the challenges of declining enrollment and expanding public options and currently lack a mechanism to understand what influences parents' reenrollment choices. The purpose of this study was to develop and validate a theoretical framework for reenrollment decisions in secular and Catholic…

This study presents the validation process of a listening test based on a communicative language test proposed by Bachman (Fundamental considerations in language testing, 1990). It was administered to third-grade high school students by the sixteen Korean Provincial Offices of Education for Curriculum and Evaluation in September 2012 to assess…

This study developed and validated an instrument for assessing teachers' perceptions of culturally responsive teaching (CRT) in technology-supported learning environments (TSLE). Data were collected from a total of 257 elementary and secondary school teachers in Taiwan during March and April 2018 to verify the reliability and construct validity of…

The Inventory of Emotions Experienced by Adolescents when Solving Mathematical Tasks (INETAM, for its acronym in Spanish), measures four influential emotions related to Math performance: Enthusiasm, Frustration, Enjoyment, and Boredom. Content validity, construct validation and item calibration analyses were performed to obtain evidence of its…

The aim of this research is to examine the dimensions of junior high school teachers' readiness for implementing a flipped classroom approach and to construct and validate an instrument--the Flipped-Classroom Teacher Scale (FCTS). Two sets of samples (170 and 495 junior high school teachers) served to explore and confirm the constructs of the FCTS…

The school climate measure (SCM) has demonstrated robust psychometrics in regionally diverse samples of high school-aged adolescents, but remains untested among early adolescents. Confirmatory factor analysis was used to establish construct validity and measurement indices of the SCM using a sample of early adolescents from public schools located…

The purpose of this study is to develop a valid and reliable measurement tool for measuring organizational health of schools. The study group consists of 429 teachers working in secondary schools in the central districts of Eskisehir/Turkey in the 2015-2016 academic year. The construct validity of the scale was examined by exploratory factor…

The BIOSEL (Biotechnology Series Learning) model is a learning model that provides opportunities for students to assemble learning through a conceptual description of the coherent and precise steps of Biotechnology implementation. The purpose of this research was to analyze validity and practicality of the BIOSEL model to improve the concept…

Supporting first-year students to adjust to their new academic environment is a crucial task in higher education. Investigating students' perceptions of fit between secondary and higher education could give higher education institutions valuable information for student feedback and support, when captured in a reliable and valid way. This study…

This study aims to design mathematical literacy instruments that have evidence of content and construct validity and are reliable for use as an assessment for learning. The research involved eight experts as instrument validators and 273 eighth-grade students of junior high school in Yogyakarta Province. The results showed that the ten…

Feedback is an important factor used in learning and teaching process. The effective use of feedback by teachers fosters learning. Therefore, it plays a crucial role to evaluate the feedback system of teachers according to students' views. As a result, valid and reliable instruments are required in this process. This study aimed to develop a scale…

The aim of the present study was to develop an attitude scale to measure students' attitudes toward out-of-school learning activities (OoSLA). The study was conducted with two separate study groups consisting of a total of 620 students. Expert opinion was sought on the content validity and face validity of the scale. An Exploratory Factor Analysis…
