Learner satisfaction is an important element in online learning because it impacts achievement motivation, success, and retention. It was the purpose of this study to develop an instrument that measures the satisfaction of learners in online learning environments. Data were collected from 335 students at higher education institutions. The Online…

In this paper, we explore the role that examples play as mathematicians formulate conjectures, and we describe and exemplify one particular example-related activity that we observed in interviews with thirteen mathematicians. During our interviews, mathematicians productively used examples as they formulated conjectures, particularly by creating…

Over the past decades, the demand for scientific research to link theory and practice so that innovative solutions can be developed through research has steadily increased (Klees & Tillmann, 2015; Sandoval & Bell, 2004). In this context, the design-based research (DBR) approach was developed, which examines the research object and the…

Objective: Understanding how children cope is an important factor in investigating the impact of adversity on child development. With children increasingly experiencing adverse situations -- such as the COVID-19 pandemic -- having methods of assessing coping strategies is an essential step in supporting self-regulation development. Parent report…

A major challenge to promoting effective early science and engineering education is the lack of reliable and validated assessments that align with current educational guidelines for science and engineering. Existing early science and engineering assessments either cover a narrow range of concepts and practices and/or are not designed in a way to…

Background: A growing number of surveys are conducted online where respondents can choose to complete the questionnaire (Lehdonvirta et al., 2020). As respondents are self-selected, there is potential that the respondents will not be an accurate representation of the population. For example, white people are disproportionately more likely to…

The aim of this research is to adapt the 24-item "Learner Autonomy Scale" developed by Sereti and Giossos (2018) in higher education samples into Turkish by examining the psychometric properties of high school and secondary school samples, and to determine whether these groups are equivalent in terms of measurement invariance. The scale…

Objective: The aim of the present study was to test the factorial invariance and convergent validity evidence of scores on the Somatic Symptom Scale (SSS)-8 with a national sample of adults living in the United States. Method: A data collection contracting service was hired to recruit a national, non-clinical sample (N = 821) of adults in the…

The insertion of Machine Learning (ML) in everyday life demonstrates the importance of popularizing an understanding of ML already in school. Accompanying this trend arises the need to assess the students' learning. Yet, so far, few assessments have been proposed, most lacking an evaluation. Therefore, we evaluate the reliability and validity of…

Classrooms are complex learning environments, with instruction, climate, and teacher--student interactions playing important roles in students' academic progress. To investigate the learning environments of deaf and hard-of-hearing (DHH) students, we developed a new observational tool called the Quality of the Learning Environment-DHH rating scale…

The Music Performance Self-Efficacy Scale (MPSES) is an important scale designed to reflect the four sources of self-efficacy of Bandura by Zelenak, and has been used in many studies of music education in the international literature in recent years. This study was carried out to ensure the validity and reliability of the Turkish translation of…

The field of geometrical optics features a broad knowledge base concerning conceptual learning difficulties and student conceptions. However, in contrast to other areas of physics, no widely used standard test instrument exists to assess middle school students' conceptual knowledge of geometrical optics. This is even more true for other areas of…

The rapid advancement of digital technology has not only affected the world of work but also students' learning. Digital learning competence (DLC) is one of the essential skills students need for effective learning in a digital environment. Despite the significant presence of secondary vocational school students in China, constituting one-third of…

In the current article, we describe the development and validation of the Social Comparison Rumination Scale. This measured was developed as a supplement to existing social comparison measures and to enable us to determine its potential relevance to perfectionism and other personality constructs. The Social Comparison Rumination Scale (SCRS) is a…

The use of drawing as an assessment tool to reveal students' conceptions in biology specifically on human organs and organ systems is not new, however, there is a deficit in the literature that attempted to explore and reflect on its usefulness and relevance specifically, in eliciting students' preconceptions related thereto. Making use of a…
