Smartphones might offer an extension of our own cognitive abilities, potentially preventing practice of certain forms of cognition. Our first study established that heavier usage of smartphones was negatively correlated with social problem solving and delayed gratification, as well as positively correlated with some aspects of critical thinking.…

There is accumulating evidence that readers continually evaluate the consistency, congruence, and coherence of text by processes of validation. Validation is initiated immediately on stimulus presentation, may proceed nonstrategically, and serves as a criterion for representational updating. However, validation exhibits a variety of deficiencies.…

In "Rules for a Flat World", Hadfield argues that although the world is becoming increasingly connected and faster paced due to leaps in technological innovation, the prevailing legal systems -- established by governments and run almost exclusively by lawyers -- have not kept pace. They are increasingly proving ill suited for and…

This study sought to a better understanding of the construct of problem solving in technology-rich environments and the effect of literacy and numeracy on problem solving. Data used in this study were drawn from Programme for the International Assessment of Adult Competencies US data which includes 5010 completed cases and a total of 1326…

How to pedagogically integrate the four STEM (science, technology, engineering, and mathematics) disciplines is a main discussion issue in STEM education. Inquiry-based learning, mathematical modeling, and tool-based pedagogy could go hand in hand to provide a possible integrated STEM pedagogical framework for mathematics and science. This…

College physics textbooks (algebra based) tend to shy away from topics that are usually thought to require calculus. I suspect that most students are just as happy to avoid these topics. Occasionally, I encounter students who are not so easily satisfied, and have found it useful to maintain a storehouse of non-calculus solutions for some common…

The Chinese New Silk Road initiative offers unique opportunities for setting up Sino-European research collaborations. Academic cooperation between countries that are rooted in completely different legal, cultural, and academic backgrounds might however also create new challenges. This article investigates the impact of these differences in the…

This study examined how financial stress was related to psychological distress as measured by the Counseling Center Assessment of Psychological Symptoms--62 (Locke et al., 2011). Data were collected from students seeking psychological services at a large midwestern university. Results indicated that higher levels of financial stress are associated…

Ethics review of research involving humans has become something of an institution in recent years. It is intended to protect participants from harm and, to that end, follows rigorous standards. Given recent changes in research methodologies utilized in medical research, it may be that ethics review for some kinds of studies needs to be reexamined.…

The development of multiple solutions for a given problem is important for learning mathematics. In the present intervention study, we analyzed whether prompting students to construct multiple solutions (more precisely: prompting them to apply multiple mathematical procedures to real-world problems) and prior self-efficacy influenced students'…

Regression mixture models are a statistical approach used for estimating heterogeneity in effects. This study investigates the impact of sample size on regression mixture's ability to produce "stable" results. Monte Carlo simulations and analysis of resamples from an application data set were used to illustrate the types of problems that…

To reach their goals, companies are on a never-ending search to find new methods for innovation. In order to tackle the complex problems, which cannot be solved by a single person, the implementation of teamwork is assumed to be applicable. With this paper, we propose a framework for Collaboration Support Systems, which aims to enhance team…

The idea of using fingers as a key component in arithmetic development has received a great deal of support, much of which is based on neuroscientific evidence. However, this body of work pays limited attention to how fingers are used and possible different outcomes in arithmetic problem solving. The aim of our paper, based on an analysis of 126…

Collecting data for cross-cultural research is time consuming and expensive. We report on techniques for efficient and effective cross-cultural data collection, drawn from 18 cross-cultural studies we conducted in 22 countries. We discuss research design, site selection and collaboration building, ethical review, cross-site protocol design, data…

Recently, Wilmer III and Costa introduced a method into the mathematics education research literature which they employed to construct solutions to certain classes of ordinary differential equations. In this article, we build on their ideas in the following ways. We establish a link between their approach and the method of successive…
