This study presents and validates the psychometric characteristics of a short form of the Critical Thinking Self-assessment Scale (CTSAS). The original CTSAS was composed of six subscales representing the six components of Facione’s conceptualisation of critical thinking. The CTSAS short form kept the same structures and reduced the number of items from 115 in the original version, to 60. The CTSAS short form was tested with a sample of 531 higher education students from five countries (Germany, Greece, Lithuania, Romania, and Portugal) enrolled in different disciplinary fields (Business Informatics, Teacher Education, English as a Foreign Language, Business and Economics, and Veterinary Medicine). The confirmatory analysis was used to test the new instrument reliability, internal consistency, and construct validity. Both the models that hypothesized the six factors to be correlated and to tap into a second-order factor representing the complex concept of critical thinking, had acceptable fit to the data. The instrument showed strong internal consistency (α = 0.969) and strong positive correlations between skills and between the skills and the overall scale (p < 0.05). Despite the unbalanced sex distribution in the population (close to 75% females), the instrument retained its factorial structure invariance across sexes. Therefore, the new instrument shows adequate goodness of fit and retained stability and reliability, and is proposed as a valid and reliable means to evaluate and monitor critical thinking in university students.

An effective instructional approach for promoting critical thinking is a challenge not only for Higher Education but also for lower educational levels. In this paper, we argue that values and knowledge education (VaKE) is an instructional approach, which could be implemented in Higher Education to promote students’ critical thinking skills and dispositions. To examine our claim, we implemented the VaKE method in an undergraduate Psychology course in a group of 27 students. During the course, students were asked to suggest a solution in a value-laden situation (dilemma) in which multiple solutions were possible. Structured diaries which followed Facione’s definition of critical thinking, including critical thinking skills and dispositions, were used to record students’ experiences. A theory-driven content analysis was carried out and results revealed that students experienced the activation of critical thinking skills and dispositions during the different steps of VaKE. This study is the first step of our work in progress showing that during the VaKE course students activated and implied critical thinking skills and dispositions.

Higher education institutions are responsible for preparing and equipping undergraduate students with the skills required by the labor market, such as critical thinking. However, academics should consider students’ pre-existing ideas before designing and implementing an instructional intervention regarding critical thinking. Drawing on the literature for conceptual change, the current study aimed to map students’ conceptualization of critical thinking and their ideas regarding the acquisition of critical thinking. In total, 243 first-year social sciences students participated in the study. To explore students’ ideas, the authors constructed an instrument with 20 scientific and non-scientific statements about critical thinking. The instrument was a two-tier questionnaire, and participants indicated their level of agreement with each statement using a 5-point Likert scale as well as their confidence in their answers. Students’ ideas were categorized into six groups depending on their endorsements for the statement and their level of confidence in their decision. Results revealed that students had insufficient conceptualization of critical thinking, and their ideas regarding how critical thinking might be acquired were not consistently aligned with those of academics. Implications for instruction are discussed considering students’ ideas on critical thinking.
