This study explored what kind of mathematics is needed in cabinetmakers' everyday work and how problem solving is intertwined in it. The informants of the study were four Finnish cabinetmakers and the data consisted of workshop observations, interviews, photos, pictures and sketches made by the participants during the interviews. The data was…

College teachers all too often still play Sage on the Stage -- lecturing to rooms full of passive and supposedly absorbed students. The cutting-edge opposite is still supposed to be the Guide on the Side -- facilitating wherever students themselves are already going, mentoring and coaching them along the way. But who says that these are the only…

If a fundamental goal of schooling is to prepare young people for the unknowable future, why do we assign students so many clearly defined tasks with predetermined solutions? According to educator and creativity expert Ronald A. Beghetto, the best way to unleash students' problem solving and creativity--and thus prepare them to face real-world…

Like numerous others before us, we argue that the educational research community would be well served by a mutually created cyberinfrastructure that encourages and supports engagement by multiple design-based researchers in working toward answers to important theory-driven research questions, moving our field toward a "bigger science"…

Can you solve the following Problem? There are 200 fish in an aquarium, and 99 percent of them are guppies. How many guppies must be removed to reduce the tank's guppy population to 98 percent? The key to this problem is to work backward by using the data given in figure 2 to determine the surface area of the top of the aquarium; then determine…

In this paper, we provide insight into the PBL project called PoLiMINT (Problem-oriented Learning in MINT). The project is located at the Bremen University of Applied Sciences and aims to introduce and foster PBL in the introductory phase of a physics study program. Concerning our general conditions, we will present our incremental implementation…

In this article, we provide some useful perspectives and experiences in mentoring students in undergraduate research (UR) in mathematical modeling using differential equations. To engage students in this topic, we present a systematic approach to the creation of rich problems from real-world phenomena; present mathematical models that are derived…

Educators usually mean different constructs when they speak of open tasks: some may refer to pure-mathematics investigative tasks while others may have authentic real-life tasks in mind; some may think of the answer being open while others may refer to an open method. On the other hand, some educators use different terms, e.g. open and open-ended,…

How can the best of mathematical problem-based learning be applied toward literature classes? Daniel Sussman, an English teacher at Moorestown Friends School in New Jersey, discusses how he uses problem solving tactics to encourage close, critical reading of fiction texts in his Jewish literature and poetry classes. He explores the challenges of…

Mathematical relationships are crucial elements to consider for learning mathematics. However, too often students pay more attention to the calculations to be done rather than the reasons for doing them. Relying on the relational paradigm to support elementary school students, we proposed two specially designed tasks to help students recognize and…

Karabatsos compared the power of 36 person-fit statistics using receiver operating characteristics curves and found the "H[superscript T]" statistic to be the most powerful in identifying aberrant examinees. He found three statistics, "C", "MCI", and "U3", to be the next most powerful. These four statistics,…

Evidence suggests that higher order linguistic functioning such as text comprehension is particularly vulnerable to emotional modulation. Gender has been identified as an important moderating variable in emotional expression such that girls tend toward internalizing emotions (e.g., sadness, anxiety) whereas boys tend toward externalizing emotions…

Knowing the facts is not enough. If we want students to develop intellectually, creatively problem-solve, and grapple with complexity, the key is in "conceptual understanding." A Concept-Based curriculum recaptures students' innate curiosity about the world and provides the thrilling feeling of engaging one's mind. This updated edition…

Years of developmental psychology research links traumatic experiences to long-term student externalizing problems (Bingenheimer et al. 2005; Denese & McEwen, 2012; Osofsky 1999; Pynoos et al. 1987; Raver, Blair & Willoughby, 2013; Shonkoff et al., 2012). A related body of work relates negative life outcomes with exposure to high-poverty,…

Prompted by William Newell's 2013 call for the Association of Interdisciplinary Studies (AIS) to consider whether to rethink its mission in light of other organizations' interests, this article begins by reflecting on similarities and differences among five of the founding organizations of a recently formed Global Alliance for Inter- and…
