A spinning top with a spherical bottom end was constructed to examine its behaviour. Experimental results were consistent with theoretical predictions.

Oscillatory motion with damping proportional to the velocity is part of all upper-class physics courses and some introductory courses; however, the emphasis is primarily on the free amplitude decay. Microelectromechanical (MEMs) accelerometers allow the acceleration to be directly measured and the velocity and displacement to be derived from it.…

The High Road/Low Road race is often used as a qualitative prediction activity. A marble is released simultaneously on two elevated tracks that differ only in the middle section where the Low Road dips before finishing at the same height as the High Road. Typically a minority of students correctly predict that the Low Road will finish first. In…

All physics is fascinating, but some stories are more exciting than others. A story that involves some of the most precise measurements ever made and a tantalizing discrepancy might be one of the most interesting. Throw in a 3200-mile journey, a heavily laden truck covered by a tarpaulin, closed-down highways with police escorts, and hushed…

This study examined (a) the effects of professional development (PD) intervention on third- to fifth-grade teachers' knowledge and skills of teaching practice for multilingual learners (MLs), and (b) the relationship between teachers' enhanced knowledge and skills, MLs' self-efficacy in learning, and MLs' academic performance. The sample consisted…

This study investigates how speakers of Mandarin interpret negative sentences with the conjunction ("he" 'and'). Our experiments test three predictions that follow from the proposal that the Mandarin conjunction is a positive polarity item (PPI) for both children and adults. On this account, the Mandarin conjunction should be interpreted…

This study calls for a broadening of the perspective on academic success. While passing exams is an essential objective of higher education, it should not overshadow another important objective which is the development of students' skills, such as becoming curious, autonomous and reflective in the learning process. This study used Academic…

This study examined whether students' perceived social interactions within different learning activities predicted their willingness to communicate (WTC) in second language (L2) classrooms. The sample was 932 undergraduate students from 8 universities learning English as a foreign language. Data of student-perceived social interactions in…

Contribution: This study examines the impact of student data and behaviors on student evaluations of teaching. It leverages campus data and employs statistical methods to explore the relationships among these indicators. A regression model is developed that integrates teaching evaluation, expected grades, and course participation, aiming to…

This article compares metalinguistic awareness among emerging bilingual and multilingual learners of English in Norwegian primary school. Participants were 120 students in grades 5-7 (aged 10-13) attending mainstream English classes in Norway and were divided into three groups based on a linguistic background questionnaire: an L1 Norwegian group,…

While it has been shown that socioeconomic status (SES) is important for children's literacy development in their first language (L1), less is known about its association with reading in a second language (L2). The present study examined the different effects of SES on the acquisition of reading in Chinese as L1 and English as L2 from ages 7 to…

This study investigates the effectiveness of a modified flipped classroom that integrated with a technology-enhanced Predict-Observe-Explain strategy to improve students' self-regulated learning abilities, learning performance and science process skills in a secondary school in Hong Kong. An experimental group of modified flipped classroom (n =…

This paper explores the challenge of achieving consistent effectiveness in integrating Mathematics Education Technology (MET) in K-12 classrooms, focusing on factors such as technology type, timing, and instructional strategies. It highlights the difficulties novice teachers face in optimizing MET compared to experienced educators, emphasizing the…

We aimed to develop a predictive model to identify risk factors associated with problem behaviour groups in 4-year-old South Korean preschoolers. Using data from the 2012 and 2014 waves of the Panel Study on Korean Children (n = 1,416), we examined how maternal parenting stress, depression, parenting behaviours, child temperament, sex, and family…

The moderating role of maternal depressive symptoms in the relationship between language skills and problem behaviours was examined in a sample of 240 preschool children (M age = 43.52 months) enrolled in Head Start programmes. This longitudinal study assessed children's language skills using the Preschool Language Scale-5. Mothers completed the…
