We use Taylor's formula with Lagrange remainder to prove that functions with bounded second derivative are rectifiable in the case when polygonal paths are defined by interval subdivisions which are equally spaced. As a means for generating interesting examples of exact arc length calculations in calculus courses, we recall two large classes of…

Science teachers play a key role in successfully implementing science education reforms and providing all students with meaningful science learning opportunities. Therefore, what core teaching competencies do science teachers need to have in their practice? This study uses fuzzy Delphi technique and Analytic Hierarchy Process to approach the above…

The aim of this study was to develop a valid and reliable measurement tool in order to determine the democracy levels of teacher candidates. During the scale development process in the research, the validity and reliability studies were conducted through three independent study groups. The first study group consisted of 627 students studying at…

Purpose: The purpose of this study is to examine learning style instruments used in Arab countries to measure higher education students' learning styles, identify the most common instruments and determine whether the reliability and validity of these instruments have been verified in Arab contexts. Design/methodology/approach: A comprehensive…

The authors present the development and examination of the "Client Assessment of Multicultural Competent Behavior" (CAMCB) scores. The CAMCB was designed to measure therapists' multicultural competent behaviors within the context of therapeutic process, from clients' perspective. In this article, three-phases of the study are presented…

The International Physical Activity Questionnaire-Short Form (IPAQ-SF) is a globally-used self-report measure of physical activity (PA). Validity evidence exists; none has evaluated the IPAQ-SF with reduced recall time. This study evaluates absolute and relative agreement for PA at all intensities, and relative to recommended guideline…

Entrepreneurship, especially among university students, measuring perception/tendency has been very popular in recent years due to reasons such as the importance of the subject, research applicability, reaching the target audience and relatively low research costs. In this context, it emphasises that the willingness, determination and…

The Career Adapt-Abilities Scale (CAAS) has been validated in several East Asian countries, but the measurement equivalence of its four dimensions and construct validity has not yet been evaluated in Japan. Results from Japanese (n = 298) and South Korean (n = 301) college students indicated good to excellent internal consistency estimates, and…

The development of social skills (SS) at various stages of life provides the basis for social and academic success throughout life. This cross-sectional study validates and verifies the reliability of the SS checklist proposed by Goldstein et al 1983. The checklist was administered, which is composed of 6 dimensions and 50 SS questions. 671…

Researchers analyzed data from a national sample of American School Counselor Association (ASCA) members practicing in elementary, middle, secondary, or K-12 school settings (N = 4,598) to test the underlying structure of the School Counseling Program Implementation Survey (SCPIS). Using both confirmatory and bifactor analyses, results suggested…

The aim of this study is to identify the basic components of the mathematical proof process in abstract algebra and to organize the proof process into phases with the help of these basic components. A basic component form was prepared by arranging a draft basic component form, which was created as a result of a document analysis in accordance with…

Increasing complexity towards harnessing the power of ICT on all levels has created uncertainty about higher educational technological capabilities and adequate strategies to develop e-readiness. In this study, an empirically grounded higher education e-readiness questionnaire in the domain of higher education was developed and validated.…

Test-taking strategies are discussed in the literature as an important factor affecting test scores and are recommended to be taken into consideration regarding the validity of tests. Although studies have been conducted for more than a quarter century, no agreement has been reached on the dimensions of test-taking strategies. The purpose of this…

Today, various methods have been developed with a purpose to determine the number of factors underlying a construct. However, there is no definitive agreement on which techniques to be preferred to extract the underlying dimensions. To this end, Exploratory Graphical Analysis (EGA), a recently proposed method, has been compared with traditional…
