It has become increasingly clear that the early use of decomposition for addition is associated with later mathematical achievement. This study examined how younger children execute a base-10 decomposition strategy to solve complex arithmetic (e.g. two-digit addition). 24 addition problems in two modalities (WA: Written Arithmetic; OA: Oral…

This study examined how students' position on social-scientific issues (SSIs) influenced their performance on attitude toward science, science conceptual and argumentation learning. It defined two positions adopted by students regarding SSIs: affirmative and oppositional. The interactions between student position and two learning environments --…

Scientific reasoning, argumentation, and problem-solving are essential skills in 21st century. They help people solve problems in daily life. This study aimed to investigate the effect of local-based teaching materials on student's argumentation, scientific reasoning, and problemsolving skills using Science Project-based Learning (SPjBL).…

This study examined children's fear responses to everyday TV news with regards to the following: (a) the consistency between mothers' observations and children's reports on TV induced fears, (b) the relationships between TV news contents that frighten children with regards to their age and gender, and (c) the most common fearful coverage of TV…

The magnetic field is a more complex and abstract physics subject than other physics subjects, causing students' low ability to solve problems. So there is a need for learning instruments to overcome these problems, especially when online learning during the COVID-19 pandemic. Research creates and implements an online problem-based learning (OPBL)…

In Realistic Mathematics Education (RME), students should reach formal mathematics knowledge and explore mathematics based on their informal knowledge. The problems chosen in the exploration process should apply mathematics to real-life situations and be suitable for students to explore and create mathematical structures. In the current study, the…

This study aimed to investigate the youth leadership qualities and characteristics of university students who volunteer at the Elazig Youth Center, Turkey. The population of the study consisted of 146 university students, 86 females and 60 males. Youth Leadership Qualities Scale, which was developed by (Cansoy & Turan, 2016), was used as the…

This paper presents research activity in the solution of geometric tasks by mathematics teachers and by mathematics teacher trainees at a College of Education as part of an advanced courses. This activity tested the level of knowledge and ability to apply it in the solution of problems that can be solved in a number of ways: by using various tools…

This qualitative study explores lower secondary school students' experiences with components of a universal school-based social and emotional learning (SEL) intervention in relation to coping with academic stress. The intervention aimed at promoting the following five social and emotional competencies (SEC): relationship skills, emotional…

Problem solving is a central focus of mathematics teaching and learning. If teachers are expected to support students' problem-solving development, then it reasons that teachers should also be able to solve problems aligned to grade level content standards. The purpose of this validation study is twofold: (1) to present evidence supporting the use…

Providing adequate proof is one essential mathematical method, but it is a difficult task for many school-age students. While previous studies have revealed the cognitive factors of proving the proof, the function of affective factors and learning engagement has been largely unexplored. This study examined the effects and processes associated with…

Understanding how physicists solve problems can guide the development of methods that help students learn and improve at solving complex problems. Leveraging the framework of cognitive task analysis, we conducted semistructured interviews with theoretical physicists (N=11) to gain insight into the cognitive processes and skills that they use in…

Using multimodal data fusion techniques, we built and tested prediction models to track middle-school student distress states during educational gameplay. We collected and analyzed 1,145 data instances, sampled from a total of 31 middle-school students' audio- and video-recorded gameplay sessions. We conducted data wrangling with student gameplay…

The KiVa anti-bullying program is an evidence based whole-school intervention and prevention program that has been implemented in a small number of New Zealand schools to help address high rates of bullying behaviors. Parents are a key component of the whole-school program as without parental support the ongoing sustainability of the program…

The Collaborative for Academic, Social, and Emotional Learning (CASEL) identifies five core, interrelated social and emotional learning (SEL) competencies that children need to be successful in school, at home, and in their community: (1) self-awareness; (2) self-management; (3) responsible decision-making; (4) relationship skills; and (5) social…
