This study described the mathematical depth in a mathematical activity carried out in a village in Turkey's Eastern Anatolia Region. This activity presented in the context of the game reflects a cultural situation of doing mathematics over time. In this context, it can identify as a study of ethnomathematics. Therefore, the cultural game was…

Robotics programming is a type of coding that combines mechanics and programming. Robotics technology facilitates coding instruction. Coding improves students' problem-solving skills. However, studies from the literature show that some teaching methods do not have a positive effect on coding skills. This study aims to examine the effects of…

It remains a challenge for teachers to integrate modeling tasks in everyday mathematics classes. Many studies have been conducted that show the difficulties faced by teachers. One of the challenging aspects in this regard is that of assessment. In the present study, a connection between structures of learners' solution strategies and cognitive…

Informed by decades of research and standards-based policies, there has been a growing demand for high-quality teaching and learning in mathematics and science classrooms. Achieving these ambitious goals will not be easy; students' opportunities for learning as shaped by the tasks they are assigned will matter the most. The purpose of this article…

In this work three examples of textbook circuits (resistor-capacitor, resistor-inductor and resistor-inductor-capacitor) have been modeled by employing the Euler method for the approximate solution of differential equations using algorithms implemented in the "Python" programming language. The aim of this work was to demonstrate how…

This paper is about an experimental problem on forced oscillations, which was given to 14-year-old primary school pupils at the Slovenian national (final) level of the physics competition in April 2019. At the time when the competition took place these pupils were approaching the end of the school year, when they encountered physics as a school…

Background: Engineering students commonly learn domain knowledge by engaging with visual representations of it. However, at times they have trouble accessing information from these representations due to the way information is encoded in features of the representation. Purpose: To describe how students engage with representation features, we…

The goals of learning mathematics are to develop thinking skills. But the results showed that critical thinking ability are still low and the lack of self confidence of students. Therefore we need a supportive learning, alternative learning is DAPIC (Define, Assess, Plan, Implement, and Communicate) Problem Solving with Realistic Mathematics…

Toddlers show high sensitivity to creator's intention when they interpret pictures. Previous research suggest that toddlers' performance can be facilitated in a picture comprehension task by making available the creator's intention that is, the social origin of picture-creation. The present study aims to test the generalizability of this…

Critical thinking and problem solving is one of the competencies that must be possessed to meet the 21st Century. This competence is very important to be mastered by students, especially vocational high school students. One learning model that can hone 21st Century competencies is Problem Based Learning. This research was carried out on productive…

As the cost of attending postsecondary education increases, a growing number of college students seek and obtain employment while attending school (Carnevale, Smith, Melton, & Price, 2015; Davis, 2012). Existing research concerning college student employment typically addresses the same question: Is working during college related to students'…

We present in this paper a pair of approaches to support mathematics educators and learners in formulating original tasks. In particular, we facilitate the posing of rich mathematical problems by using two novel methods that were created by a mathematics department at a K-12 school in the United States, and further developed alongside our students…

In this article, the authors share the potential for two types of atypical arrays (composite and partially hidden) to stimulate initial multiplicative ideas and strategies from students in a second-grade classroom. Composite arrays are defined here as nonarrays that are composed of multiple smaller complete arrays. The atypical arrays were…

Research on number sense presents contradictory arguments and results regarding the effects of context-based tasks and activities on students' number sense. The aim of this study was to examine fourth-grade elementary school students' number sense as they solve context-based (CB) and non-context-based (NCB) items. A survey design was employed and…

Job autonomy -- employees' freedom to schedule and organise their work independently according to their own experience and preferences -- is a major factor in job satisfaction. However, it is not granted to many employees in Israel, and the authors of this article were interested in the reasons for this. Based on data from the Programme for the…
