Critical consciousness represents the analysis and critique of structural inequalities, the motivation and perceived capacity to effect change, and social action to redress inequity. A wave of recent instruments measuring critical consciousness has been rigorously validated. Yet, whether these measures efficiently assess different levels of…

In addition to the studies on what the 21st century skills are, how these skills will be gained by the students, that is, after completing the K-12 and university education, the problem of how the students will graduate with these skills has become one of the most important questions waiting for an answer all over the world and it has been an…

The main aim of this study is to develop a useful, valid, and reliable two-tier proportional reasoning skill test for middle school 7th and 8th-grade students. The research was carried out using the sequential explanatory mixed method. The study group of this research comprised of 391 (n[subscript 7th-grade]=223, n[subscript 8th-grade]=168)…

This article reports the development and psychometric requisites of Visions About Future (VAF), a measure to assess optimism, pessimism, and hope in early adolescence. Two different studies involving Italian middle school students were conducted. With the first study, the items were developed and the factor structure verified by using item…

This study presents an exemplar for psychometric evaluation and modification of established measures when applied to new populations. Specifically, we describe the use of two subscales (Career Decision-Making Self-Efficacy Scale and Math/Science Self-Efficacy Scale) from the Middle School Self-Efficacy Scale (MSSES) as outcome measures in an…

Mathematical creativity instrument is a tool to assess students' creative thinking skills in solving mathematical problems. Mathematical creativity has a pivotal role in improving the quality of life, solving problems, making a change, and increasing the efficiency and effectiveness of a system. Unfortunately, there is a gap in the assessment of…

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?…

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…

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 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…

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…

This article describes the development and validation of an Innovation Attitude Survey (IAS) composed of 16 Likert-type items selected to measure middle school students' attitudes toward innovation and leadership in the advancement of new ideas. The goal of developing the IAS was to identify desirable dispositions that may be related to future…

Psychological sense of community among early adolescents has been investigated using instruments developed for adolescents/adults or ad hoc scales. The aim was to contribute to the validation of a scale of Sense of Community in Early Adolescents (SoC-EA) using a 3-year longitudinal study. Participants were 576 Italian students attending middle…
