This symposium brings together a panel of researchers using contrasting case methodology to analyze computer-supported collaborative learning in a wide range of learning environments. Such analyses can help researchers better understand the differences in the collaborative processes by sharpening researchers' perception and facilitating the discovery of(More)
Research on computer-supported collaborative learning has shown that students need support to benefit from collaborative activities. While classical collaboration scripts have been effective in providing such support, they have also been criticized for being coercive and not allowing students to self-regulate their learning. Adaptive collaboration support,(More)
We combined two different instructional methods both of which have been shown to improve students' learning in mathematics: Learning with intelligent tutoring systems (Koedinger, Anderson, Hadley, & Mark, 1997) and collaborative problem solving (Berg, 1993). The problem-solving guidance provided by an intelligent tutoring system is effective, but because it(More)
Interest in developing improved instructional methods for mathematics has increased since TIMSS and PISA. In our project, we introduce a new way to promote knowledge acquisition in mathematics: we enhanced the Cognitive Tutor Algebra, an intelligent tutoring system for learning mathematics in high school that only has been used for individual learning so(More)
While research has generally shown that collaboration may facilitate student learning in mathematics, such positive effects are not always found. We argue that the effectiveness of collaboration may depend on the type of knowledge the instruction targets: The interaction with a partner can slow down students and may thus decrease the amount of practice(More)
CSCL includes a wide range of scenarios that integrate individual and collaborative learning. Scripts have repeatedly proven useful for guiding learners to engage in specific roles and activities in CSCL environments. The effective mechanisms of scripts in stimulating cognitive and collaborative processes, however, are not yet well understood. Moreover,(More)
