This paper uses evidence-centered assessment design (ECD) to structure and analyze a laboratory activity where students collect and represent titration curve data to determine acid strength in terms of molarity and dissociation constant. Following principles of multidimensional learning, the activity prompts students to demonstrate knowledge of…

The history of mathematics educational reform is replete with innovations taken up enthusiastically by early adopters without significant transfer to other classrooms. This paper explores the coupling of coding and mathematics education to create the possibility that coding may serve as a Trojan Horse for mathematics education reform. That is,…

Despite the critical societal importance of computer security, security is not well integrated into the undergraduate computing curriculum. Security classes and tracks treat security issues as separable topics as opposed to fundamental issues that pervade all aspects of software development. Recently, there has been an increasing focus on security…

In this work we explored proof schemes used by 41 middle school students when confronted with four mathematical propositions that demanded verification of accuracy of statements. The students' perception of mathematically complete vs. convincing arguments in different mathematics branches was also elicited. Lastly, we considered whether the…

The author has worked for three days on a range of mathematical tasks in order to gain a deeper understanding of the role of notation in mathematics education. The general conclusions were that while mathematical notation can be powerful it can also be obstructive. In this article, the author explores the importance on notation in supporting…

The purpose of this article is to provide a comprehensive review of the published research-based strategies used in content area instruction for students with autism spectrum disorders (ASD). Twenty-eight (N = 28) studies published from 2000-2012 that met the criteria for inclusion were located, reviewed, and synthesized. Findings revealed the…
