Models of self-regulated learning (SRL) describe the complex and dynamic interplay of learners’ cognitions, motivations, and behaviors when engaged in a learning activity. Recently, researchers have begun to use fine-grained behavioral data such as think aloud protocols and logfile data from educational software to test hypotheses regarding the cognitive and metacognitive processes underlying S...

In the study of random processes, dependence is the rule rather than the exception. To facilitate the related statistical analysis, it is necessary to quantify the dependence between observations. In the talk I will briefly review the history of this fundamental problem. By interpreting random processes as physical systems, I will introduce physical and predictive dependence coefficients that q...

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...
