In this study, we attempt to put in question students' spontaneous and uncritical application of the simple and neat mathematical formula of linearity. This is impelled with the help of a written test involving geometrical problems, which is based on an original experimental setting. In this setting, grade 9 and 10 students were instructed first…

Response to Intervention (RtI) offers a comprehensive model for the prevention of delays in learning and behavior. While this problem-solving framework was initially designed for application within Kindergarten to 12th grade programs, there is substantial research that supports the value of the model for application within early childhood…

Despite student interest, the heart is often a poorly understood topic in biology. To help students understand this vital organ's physiology, the author created this investigation activity involving the mammalian heart and its role in the circulatory system. Students design, build, and demonstrate working artificial "hearts" to exhibit what they…

This paper presents the IPS-I-model: a model that describes the process of information problem solving (IPS) in which the Internet (I) is used to search information. The IPS-I-model is based on three studies, in which students in secondary and (post) higher education were asked to solve information problems, while thinking aloud. In-depth analyses…

Theories that explain the gender discrepancy in mathematics almost universally explain why boys are "better at math" than girls while failing to adequately account for girls' higher grades in math classes or better performances on tests of computational ability. This article develops a new, more comprehensive theoretical model that explains girls'…

In the Netherlands, national assessments at the end of primary school (Grade 6) show a decline of achievement on problems of complex or written arithmetic over the last two decades. The present study aims at contributing to an explanation of the large achievement decrease on complex division, by investigating the strategies students used in…

The 13th iteration of the International Conference on Educational Data Mining (EDM 2020) was originally arranged to take place in Ifrane, Morocco. Due to the SARS-CoV-2 (coronavirus) epidemic, EDM 2020, as well as most other academic conferences in 2020, had to be changed to a purely online format. To facilitate efficient transmission of…

We propose a new paradigm for building a Management Information Systems course that focuses on laboratory activities developed collaboratively using Computer-Mediated Communication and Collaboration tools. A highlight of our paradigm is the "practice what you preach" concept where the computer communication tools and collaboration…

The purpose of this exploratory qualitative study was to determine what successful managers do to create healthy work environments in a healthcare organization. Managers using exemplary behaviors were selected and interviewed based on employee satisfaction surveys, and focus groups were conducted with employees who worked for them. Effective…

Newbrough's Third Position is discussed in terms of its utility as a framework within which to understand and resolve interpersonal differences, seemingly irresolvable diametric differences, and conflictual situations. The framework's essential elements and its application is illustrated through the presentation of a series of fictitious scenarios…

According to the U.S. Department of Justice (www.usdoj.gov), Community Policing is defined as: "The focus on crime and social disorder through the delivery of police services that includes aspects of traditional law enforcement, as well as prevention, problem-solving, community engagement, and partnerships. The community policing model balances…

The ability to use analogical reasoning traditionally has been considered a higher-level ability characteristic of thinking of older children and adults. Such reasoning has not been thought to be accessible to younger children. However, recently, it has been suggested that younger children's ability to understand and solve analogical problems…

This note describes an interdisciplinary project designed to enhance students' knowledge of the basic techniques taught in a multivariable calculus course. The note discusses the four main requirements of the project and then the solutions for each requirement. Concepts covered include differentials, gradients, Lagrange multipliers, constrained…

As the number of students with disabilities who are entering postsecondary education continues to rise, the need for their adequate preparation to successfully complete programs of study is a critical concern. A common characteristic of students who successfully enter and complete programs of study in postsecondary settings is that of having…

Three widely used sixth-grade textbooks were studied to see how fraction concepts were represented. The textbooks selected were "Connected Mathematics," "Middle Grades MathThematics," and Glencoe's "Mathematics: Applications and Concepts Course 1." Three specific areas were examined: representation mode, model, and problem context. Results of…
