In the first part of the dialogue between theories, which gave rise to a paper in this journal, we discussed the role played by normativity in didactics. In this work, with the aim of taking a step forward in this dialogue, we state explicitly some of the postulates of the anthropological theory of the didactic. They shape the object of study, the…

Teachers are tasked with the important role of educating and empowering the Nation's youth. Although teaching is a rewarding vocation, teachers are subjected to risk and liabilities on a daily basis. The rising number of school-based litigation and the litigious nature of today's society bolster the need for teachers to abide and understand the…

Postsecondary honors educators are adept at identifying problems and proposing solutions in honors education, but they may not disseminate their solutions effectively. This essay argues that honors administrators should familiarize themselves with the professional and scholarly resources that NCHC institutional membership affords, and then they…

This article introduces an account of moral education grounded in Zagzebski's recent "Exemplarist Moral Theory" and discusses two problems that have to be solved for the account to become a realistic alternative to other educational models on the market, namely the limited-applicability problem and the problem of indoctrination. The…

According to the World Economic Forum (2016), "more than one third (36%) of all jobs across all industries" (p.21) need problem-solving as a key skill. Trilling and Fadel (2009) noted the shift from industrial to knowledge-based economies, requiring students not only to possess content knowledge but also have skills that enable them to…

Lord's (1980) equity theorem claims observed-score equating to be possible only when two test forms are perfectly reliable or strictly parallel. An analysis of its proof reveals use of an incorrect statistical assumption. The assumption does not invalidate the theorem itself though, which can be shown to follow directly from the discrete nature of…

Imagination is necessary for scientific practice, yet there are no in vivo sociological studies on the ways that imagination is taught, thought of, or evaluated by scientists. This article begins to remedy this by presenting the results of a qualitative study performed on two systems biology laboratories. I found that the more advanced a…

In this paper we argue that the choice of research methods reflects the theoretical framework even before these methods have been put to use in case studies. We understand the term 'case study' broadly in this paper and argue that neither thinking of them as cherry-picked cases to support preconceived ideas about mathematical practices nor…

By using Shlomo Vinner's credit system concept, we show that summative assessment is a rather vague and underrepresented notion in mathematics education literature. The emotional drive behind this article is expressed in the following questions: How is it possible to look for concrete exclusionary school practices that qualify some and disqualify…

Analysis of collisions is standardly included in the introductory physics course. In one dimension (1D), there do not seem to be any unusual issues: Typically, the initial velocities of the two colliding objects are specified, and the problem is to find the final velocities. In 1D there are therefore two unknown variables. One can write the…

We present a technique that examines handwritten equations from a student's solution to an engineering problem and from this estimates the correctness of the work. More specifically, we demonstrate that lexical properties of the equations correlate with the grade a human grader would assign. We characterize these properties with a set of features…

Membrane separation processes, from reverse osmosis to ultrafiltration to microfiltration, are gradually receiving more and more emphasis in undergraduate chemical engineering curricula. Of these processes, ultrafiltration tends to be the most amenable to the standard chemical engineering approach of theory development, mass and/or energy…

The "big bad wolf" chased the squealing children around the playground as they looked for a place to hide. Because Mr. Lòpez and Ms. Kim had introduced the work of engineers and the engineering design process into their unit on The Three Little Pigs, they knew their preschool students would choose a structure that could withstand any…

Mathematical representation has an essential role in solving mathematical problems. However, there are still many mathematics education students who have difficulty in representing ill-structured problems. Even though the ill-structured-problem-solving tasks designed to help mathematics education students understand the relevance and…

A substantial number of randomized trials of educational interventions that have been conducted over the past two decades have produced null results, with either no impact or an unreliable estimate of impact on student achievement or other outcomes of interest. The investment of time and money spent implementing such trials warrants more useful…
