This paper was inspired by the work of a previous contributor on the subject of modelling plague epidemiology by comparing it to the physics of series radioactive decay, RC transients, and fluid dynamics. An Arduino-based experiment to illustrate the fluid-dynamical case is described. Attention is drawn to important differences between systems…

Background: Congenital heart disease is the most common birth defect in the world. Medical advancements in pediatric cardiac surgery have led to an increased number of adults with congenital heart disease (ACHD). PA was discouraged for ACHD patients in the past however, today it is strongly encouraged for this population to remain active.…

There has been a lack of research into conceptually teaching the structure of contextual problems to kindergarten students. This is despite the popularity of contextual problems and the difficulties that students have with them. This study focuses on creating a textless, image-based application that uses the Triplet Structure Model to teach about…

This article is a response to Amanda Lewis, Margaret Hagerman, and Tyrone Forman's the Sociology of Race & Racism: Key Concepts, Contributions & Debates. Sociology and education, like any scholarly areas, have veins that reinforce racism and some that astutely assess, theorize, and challenge White supremacy. In this article, I explore the…

In this article, the authors examine the value of survivor leaders in organizations helping women transition out of the sex trade and how organizations can best utilize survivor leaders. They interviewed 10 women who have been out of the sex trade from between 3 and 20 years. They found survivor leaders (a) created relatability for participants…

As part of their professional competencies, science teachers need an elaborate meta-modelling knowledge as well as modelling skills in order to guide and monitor modelling practices of their students. However, qualitative studies about (pre-service) science teachers' modelling practices are rare. This study provides a category system which is…

Democratic public schooling prepares for and models collective self-governance in a complex society where the people are subject to various forms of governmental power. The common or public school is the main way democratic nations prepare their people for participation, yet in modern versions democracy is contested through school curriculum and…

Studies of scientific practice demonstrate that the development of scientific models is an enactive and emergent process (e.g., Pickering 1995; Chandrasekharan and Nersessian 2017). Scientists make meaning through processes such as perspective taking, finding patterns, and following intuitions. In this paper, we focus on how a group of fourth…

The article is dedicated to the students' social adjustment to acknowledged informative exercises problems. The study uses a modeling method to build preservice teachers social adaptation pedagogical model. The model comprises a list of operations contributory to successful students social evolution to instructional activities. Students'…

Many introductory physics courses begin with the teaching of motion and kinematics. This naturally leads to the use of constant acceleration equations to solve various problems involving common motions (free fall being a notable example). Students can sometimes get the impression that these equations are the only thing they need to remember in…

In recent years, there has been a proliferation of adaptive learner models that seek to predict student correctness. Improvements on earlier models have shown that separate predictors for prior successes, failures, and recent performance further improve fit while remaining interpretable. However, students who engage in "gaming" or other…

Each time a learner in a self-paced online course seeks to answer an assessment question, it takes some time for the student to read the question and arrive at an answer to submit. If multiple attempts are allowed, and the first answer is incorrect, it takes some time to provide a second answer. Here we study the distribution of such…

The Republic of Korea is well known as a leader of gifted science education due to the significant progress it has made in the past two decades. This paper aims to provide a historical perspective of gifted science education in Korea by interviewing a key figure in the Korean science education community. This paper explores the various…

The content and direction of policy can be impacted upon by broader political and economic influences that are of central concern to the government in office. With regard to education, the concepts of inclusion and special educational needs and disability (SEND) are at the forefront of professional pedagogy and provision. These concepts, although…

A three-stage professional development (TSPD) model for training experienced teachers to become teachers' leaders is presented here, along with a study assessing its value. The three stages of the model are: a "basic training" stage, a "master-teacher" stage, and an "independent implementation" stage. This qualitative…
