Beyond logging of fingertip actions: analysis of collaborative learning using multiple sources of da
In this article we discuss key requirements for collecting behavioural data concerning technology-supported collaborative learning activities. It is argued that the common practice of analysis of computer generated logfiles of user interactions with software tools is not enough for building a thorough view of the activity. Instead more contextual information is needed to be captured in multiple media like video, audio files, snapshots, etc, in order to re-construct the learning process. A softwa

"A Damaging Impression of Hollywood Has Spread": Movie "Czar" Eric Johnston Testifies before HUAC
The House Committee on Un-American Activities (HUAC) held hearings in October 1947 on Communist activity in Hollywood. In the following testimony, Eric Johnston, a successful businessman who in 1945 succeeded Will H. Hays as President of the Motion Picture Association of America--the industry's institution for self-regulation--defended Hollywood against HUAC's attacks and complained vigorously that the "atmosphere of fear" resulting from the investigation precluded the production of "good and ho

Quantitative and Qualitative Research: Conflicting Paradigms or Perfect Partners?
This paper will examine the use of quantitative and qualitative methods as complementary research methods. It asks the fundamental question wether these two approaches can be used jointly in a principled manner. The pressure in educational research has been towards using the two methods alongside each other. In applied research the use of the two approaches in the same project is accepted yet we still find serious objections raised to such work when it is presented in a more formal context. Eval

The Microevolution of Mathematical Knowledge: The Case of Randomness
In this article, we explore the growth of mathematical knowledge and in particular, seek to clarify the relation between abstraction and context. Our method is to gain a deeper appreciation of the process by which mathematical abstraction is achieved and the nature of abstraction itself, by connecting our analysis at the level of observation with a corresponding theoretical analysis at an appropriate grain size. In this article, we build on previous work to take a further step toward constructin

An Activity to Introduce the Geoscience Perspective
This exercise is intended to connect students to geology and to remind them of the diverse ways in which people, including geoscientists, relate to rocks. Groups of students are asked to examine rock samples from specific perspectives such as sculptors, landowners or geologists, and then present relevant observations and questions. Next, individuals write one-minute papers summarizing what they have learned and evaluating the activity. On this Starting Point page, users can access information ab

Science identifies speed as a ratio (distance over time). When combined with human innovation, speed can be applied exponentially. Speed is COSI's (Center of Science and Industry) newest traveling exhibit that examines the way in which speed impacts our lives. Speed has become blended and blurred into complex human desires to fall faster, to drop farther, and to climb higher. This website will demonstrate how speed touches our world.
