Reasoning for complexity is a fundamental competency in these complex times for solutions to social problems and decision-making. The purpose of this paper is to demonstrate the validity and reliability of the eComplexity instrument by presenting its psychometric properties. The instrument consists of a Likert-type scale questionnaire designed to…

Attitudes towards learning chemistry have been little studied in secondary school students, especially regarding dimensions related to problem solving, the molecular atomic perspective of chemistry, and real-world connection of chemistry. In the present study, we first aimed to design and assess the psychometric properties of the attitude to…

Genetics plays an increasing role in modern life as evidenced by the development of revolutionary techniques such as CRISPR-based genome editing and the rise of personalized genome services. However, genetics is difficult to learn; known issues include its abstract nature, different scales, and technical language. Pedigree analysis is a…

The purpose of this study was to develop an instrument for measuring students' mathematics anxiety scale (MAS) with high psychometric property. A survey research design was used involving 510 students randomly selected from secondary schools. Exploratory factor analysis (EFA) was carried out to determine the number of factors to be retained in the…

Purpose: This study examined the quality of English test items using psychometric and linguistic characteristics among Grade Six pupils. Method: Contrary to the conventional approach of relying only on statistics when investigating item quality, this study adopted a mixed-method approach by employing psychometric analysis and cognitive interviews.…

This study investigates the role of automated scoring and feedback in supporting students' construction of written scientific arguments while learning about factors that affect climate change in the classroom. The automated scoring and feedback technology was integrated into an online module. Students' written scientific argumentation occurred…

The Anatomy Learning Experiences Questionnaire (ALEQ) was designed by Smith and Mathias to explore students' perceptions and experiences of learning anatomy. In this study, the psychometric properties of a slightly altered 34-item ALEQ (ALEQ-34) were evaluated, and correlations with learning outcomes investigated, by surveying first- and…

Asian students often perform well in international science and mathematics assessments. Their attitude toward technical subjects, such as physics, remains curious for many. The present study examines Singapore school students' views on various aspects of physics according to whether they intend to choose physics as an advanced field of study. A…

We report on research carried out to improve teaching and student engagement in the introductory astronomy course at the University of Cape Town. This course is taken by a diverse range of students, including many from educationally disadvantaged backgrounds. We describe the development of an instrument, the Introductory Astronomy Questionnaire…

This study examined the effects of cognitive load experienced by e-learners as they negotiated the tasks required for successful participation within an asynchronous course room, specifically examining the relationship between measured cognitive load and the learners' confidence in completing their course. The results indicated that learner…

Objective: This comparative study evaluated the readability and test-retest reliability of a questionnaire designed to assess the attitudes, beliefs behaviours and sources of information about HIV/AIDS among young adults recruited from universities in the United States of America (USA), Turkey and South Africa. Design/Setting: The instrument was…

The purpose of the study is to present research focused on validating the four algebra cognitive models in Gierl, Wang, et al., using student response data collected with protocol analysis methods to evaluate the knowledge structures and processing skills used by a sample of SAT test takers.
