In this study we examined the effectiveness of self-regulated learning (SRL) training in facilitating college students’ science learning with hypermedia. Sixty (N = 60) undergraduate students were randomly assigned to either a training condition or a control condition and used a hypermedia environment to learn about the circulatory system. On Day 1, all participants were administered a pretest ...

[Note: These pages were my rough private notes that I made in preparation for the talk I gave. Needless to say, I didn’t cover all this material in my talk. I am willing, but hesitant, to put it on the web because of three reasons, the primary one being that I haven’t yet put in proper references for any of the results cited. The second reason is that in its next draft I will be separating much...

The development of algebraic topology in the twentieth century is one of the most important advances of its time. However, how did this development get under way? What forces worked to advance the subject, and perhaps more interestingly, to retard the development in its early days? In this talk I will present some historical approaches to these questions and the answers they produce. Toutes les...

In this paper, we investigate the effect of context on usability evaluation. The focus is on how children behave and perform when they are tested in different settings. Two most commonly applied usability evaluation methods: the think-aloud and constructive interactions are applied to the children in different physical contexts. We present an experimental design involving 54 children participat...

It is widely believed that chiral symmetry is restored not only at high temperatures, but also at high nuclear densities. The drop of the order parameter of the chiral phase transition, the chiral condensate, with density has indeed been calculated in various models and is as such a rather robust result. In this talk I point out that the connection of this property with actual observables is fa...

The study investigated English as a foreign language learners’ metacognitive awareness of reading strategy use. The participants were 12 Taiwanese college students who were required to read aloud and think aloud the eight designated texts. The collected data came from the pre-and postquestionnaires and an interview on metacognition in EFL reading as well as participants’ thinkaloud protocols. T...

Program comprehension research can be characterized by both the theories that provide rich explanations about how programmers comprehend software, as well as the tools that are used to assist in comprehension tasks. During this talk I will review some of the key cognitive theories of program comprehension that have emerged over the past thirty years. Using these theories as a canvas, I will the...

Chinese characters can be compared to a molecular structure: a character is analogous to a molecule, radicals are like atoms, calligraphic strokes correspond to elementary particles, and when characters form compounds, they are like molecular structures. In chemistry the conjunction of all of these structural levels produces what we perceive as matter. In language, the conjunction of strokes, r...
