Divergent thinking (DT) ability is widely regarded as a central cognitive capacity underlying creativity, but its assessment is challenged by the fact that DT tasks yield a variable number of responses. Various approaches for the scoring of DT tasks have been proposed, which differ in how responses are evaluated and aggregated within a task. The…

Scoring in creativity research has been a central problem since creativity became an important issue in psychology and education in the 1950s. The current study examined the psychometric properties of 27 creativity indices derived from summed and averaged scores using 15 scoring methods. Participants included 2802 middle-school students. Data…

Creativity in science education and research on scientific creativity are becoming increasingly significant. Several domain-specific assessment tools focusing on different aspects of scientific creativity have been developed. Some of these tools consider a wide range of aspects, while others focus on very specific science-related aspects, thereby…

This study aimed to develop and validate the Creative Problem-Solving Skills Test (CPSS-T), grounded in Torrance's creativity theory, to assess these skills in university students. The CPSS-T consists of five open-ended question types, each designed to measure different aspects of creative problem-solving: Alternative Use, Hypothetical Scenario,…

Considerable research has been devoted to exploring aspects of higher-order thinking across various disciplines and in daily life. However, insufficient attention has been paid to synthesizing core dimensions of higher-order thinking, particularly within subject-specific contexts. Moreover, there is a lack of reliable and valid methods for…

The objective of this study was to develop a measure that possesses both reliability and validity in order to evaluate innovative thinking within the realm of education. To achieve this, the instrument's validity and reliability were evaluated through quantitative methods in two distinct phases. A team of educational experts conducted the process…

This study describes the development, validity, and reliability processes of a scientific creativity test for pre-university students, specifically in chemistry. A Chemistry Scientific Creativity Test (CSCT) was constructed based on an analysis of the Scientific Creativity Structure Model (SCSM), Torrance Tests of Creative Thinking (TTCT), and…

Creativity can be measured with a variety of methods including self-reports, others reports, and ability tests. While typical self-reports are best understood as weak proxies of creativity, biographical reports that assess previous creative activities seem more promising. Drawbacks of such measures -- including skewed item distributions, a lack of…

Mathematical creativity is perceived as an increasingly important aspect of everyday life and, consequently, research has increased over the past decade. However, mathematical creativity has mainly been investigated in children and adolescents so far. Therefore, the first goal of the current study was to develop a mathematical creativity measure…

This study aims to analyze the reliability generalization of the computational thinking scale. There are five dimensions of computational thinking: creativity, algorithmic thinking, cooperativity, critical thinking, and problem-solving. A Bonett transformation was used to standardize the reliability coefficient of Cronbach's alpha. A…

One of the best-known and most frequently used measures of creative idea generation is the Torrance Test of Creative Thinking (TTCT). The TTCT Verbal, assessing verbal ideation, contains two forms created to be used interchangeably by researchers and practitioners. However, the parallel forms reliability of the two versions of the TTCT Verbal has…

Originality is scored based on standard zero-originality lists (ZOLs) in the Torrance Tests of Creative Thinking (TTCT). The applicability of those ZOLs to diverse groups has not been examined. We examined the consistency of TTCT-Figural's sample-based (SB) ZOLs and the published ZOLs based on a sample of predominantly African American college…

Background: The originality of divergent thinking (DT) production is one of the most critical indicators of creative potential. It is commonly scored using the statistical infrequency of responses relative to all responses provided in a given sample. Aims: Response frequency estimates vary in terms of measurement precision. This issue has been…

The original 90-item Creative Behavior Inventory (CBI) was a landmark self-report scale in creativity research, and the 28-item brief form developed nearly 20 years ago continues to be a popular measure of everyday creativity. Relatively little is known, however, about the psychometric properties of this widely used scale. In the current research,…

Open-ended verbal creativity assessments are commonly administered in psychological research and in educational practice to elementary-aged children. Children's responses are then typically rated by teams of judges who are trained to identify original ideas, hopefully with a degree of inter-rater agreement. Even in cases where the judges are…
