Adults exhibit strong preferences when framing symmetrical relations. Adults prefer, for example, "A zebra is like a horse" to "A horse is like a zebra," and "The bicycle is near the building" to "The building is near the bicycle." This is because directional syntax requires more typical or prominent items (i.e., reference points) to be placed in the complement position. Three experiments with ...

The extent and quality of Discipline-Based Education Research (DBER) at the postsecondary level have grown substantially in recent years. Associated research findings are central to current reform efforts to transform science, technology, engineering, and math (STEM) education in colleges and universities across the United States. The increased visibility of DBER efforts creates opportunities a...

concepts in action. For instance, conditional probability and Bayes’ Theorem can be a challenge for some, treated as formulas to be memorized without intuitive understanding; teaching an introductory course on statistical jurisprudence provides one with the opportunity to explain the theory of subjective probability [13] in terms of jurors’ willingness to bet on legal outcomes and to view Bayes...

We present an educational math game, including a teachable agent and a social chat, that trains basic arithmetic skills with a focus on grounding base-ten concepts in spatial representations. It employs a board-game design with a variety of different sub-games, game modes and levels of difficulty. When a student has learnt to play one of the sub-games, she may teach it to her Teachable Agent (T...

Implementing multi-player networked games by broadcasting the player’s input and leŠing each client calculate the game state – a scheme known as lock-step simulation – is an established technique. However, ensuring that every client in this scheme obtains a consistent state is infamously hard and in general requires great discipline from the game programmer. Œe thesis of this report is that in ...
