'Mathematical sophistication' behaviours are often exercised by mathematicians in their work. In this article, the importance of mathematical sophistication will be discussed and three mathematics problems that activate mathematical sophistication behaviours will be presented.

Achievement tests are commonly used in education to evaluate students' academic performance and proficiency in specific subject areas. However, there is a major problem that threatens the validity of achievement test scores which is test-taking disengagement. Respondents provide answers that are inconsistent with their true ability level and can…

Background: With the development of computational literacy, there has been a surge in both research and practice application of text-based and block-based modalities within the field of computer programming education. Despite this trend, little work has actually examined how learners engaging in programming process when utilizing these two major…

Deconversion is a biographical change in which one goes from claiming adherence to a religion to departing from it. A meaning system model can help us understand the processes through which deconversion occurs. Drawing on that framework, we explored how perceiving hypocrisy in one's religious setting influences adolescent deconversion. Irrational…

Parents and teachers are significant authority figures that substantially impact adolescents' psychological and cognitive development, including their creativity. The current study investigated the relationship between adolescents' attitudes toward authority (parents and teachers) and innovative behavior and examined the mediating effects of…

Coping Power (CP) is a preventive intervention that focuses on reducing child externalizing problems. Although it is typically delivered in a group format (GCP), individually-delivered CP (ICP) has produced greater mean reductions in externalizing problems. However, standard analysis of randomized trials loses individual-level information…

Many low-stakes assessments, such as international large-scale surveys, are administered during time-limited testing sessions and some test-takers are not able to endorse the last items of the test, resulting in not-reached (NR) items. However, because the test has no consequence for the respondents, these NR items can also stem from quitting the…

Although much of the national opt-out movement is parent driven, the Colorado opt-out movement involved considerable efforts from high school students. This study explores the geography of the Colorado opt-out movement among secondary students, drawing upon social movements theory. We utilize the Colorado Measures of Academic Success (CMAS) as a…

Process data are becoming more and more popular in education research. In the field of computer-based assessments of collaborative problem solving (ColPS), process data have been used to identify students' test-taking strategies while working on the assessment, and such data can be used to complement data collected on accuracy and overall…

Background: Whether parental permission of alcohol and other drug use in a home environment is protective against substance-related negative outcomes remains controversial. We investigated substance use at home, with or without parental knowledge, and its association with substance-related consequences. Methods: The sample consisted of 21,207 U.S.…

Students' learning environments often change during school career, due to school transitions and the introduction of educational innovations, causing discontinuity in teaching and learning. Success of students entering a new learning environment depends in part on their prior expectations of education, as these influence later perceptions.…

Background: Examinees may not make enough effort when responding to test items if the assessment has no consequence for them. These disengaged responses can be problematic in low-stakes, large-scale assessments because they can bias item parameter estimates. However, the amount of bias, and whether this bias is similar across administrations, is…

Former literature found that various 'different' students experience exclusion and rejection by their peers in schools. This may be linked with the attitudes that their school and classmates hold towards them. Identifying someone as 'Other' may indeed result in prejudicial attitudes which, in turn, can lead to his/her marginalisation and…

Online learning has become the new educational pattern during the COVID-19 pandemic and is likely to supplement conventional schooling in the post-pandemic world. Lacking prior online learning experiences, the population of K-12 students deserves our special attention. Using purposeful sampling, this study investigated K-12 online learning…

In this explorative study, we investigate how sequences of behaviour are related to success or failure in complex problem-solving (CPS). To this end, we analysed log data from two different tasks of the problem-solving assessment of the Programme for International Student Assessment 2012 study (n = 30,098 students). We first coded every…
