Intuitive conceptions in mathematics guide the interpretation of mathematical concepts. We investigated if they bias teachers' conceptions of student arithmetic word problem solving strategies, which should be part of their pedagogical content knowledge (PCK). In individual interviews, teachers and non-teaching adults were asked to describe…

The purpose of this study was to evaluate the effect of a multicomponent mathematics intervention (modified schema-based instruction, video anchors, and goal setting with self-graphing) on mathematical problem-solving skills of secondary students with intellectual and developmental disabilities. Three participants were taught to solve percent of…

The purpose of this case study is to examine the problems that prospective primary school teachers posed related to the basic mathematical operations with whole numbers and to determine their problem posing abilities. The data was collected from seventy-two prospective primary school teachers through the Semi-Structured Problem Posing…

The purpose of this study is to describe students' metacognition level in solving scientific literacy. This research use the descriptive method. The subject of this research is 99 students of grade XI in SMA Batik 2 Surakarta. Data collection methods used are test methods which its instruments based on an indicator of scientific literacy and…

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…
