Learning Chemistry through Collaboration: A Wizard-of-Oz Study of Adaptive Collaboration Support1

چکیده
Chemistry students often learn to solve problems by applying well-practiced procedures, but such a mechanical approach is likely to hinder conceptual understanding. We have developed a system aimed at promoting conceptual learning in chemistry by having dyads collaborate on problems in a virtual laboratory (VLab), assisted by a collaboration script. We conducted a small study to compare an adaptive and a non-adaptive version of the system, with the adaptive version controlled by a human wizard. Analyses showed a tendency for the dyads in the adaptive condition to collaborate better and to have better conceptual understanding. We present our research framework, our collaborative software environment, and results from the wizard-of-oz study.

Using an Adaptive Collaboration Script to Promote Conceptual Chemistry Learning
Chemistry students often learn to solve problems algorithmically, applying well-practiced procedures to problems. Such an approach may hinder development of conceptual understanding. We propose to promote conceptual learning by having pairs of students collaborate on problems in a virtual laboratory (VLab), assisted by a computer-mediated collaboration script that guides the students through th...
متن کاملSimulating pedagogical agents in a virtual learning environment
This paper presents and analyses data from a usability experiment conducted at the University of Bergen in Norway. The experiment is entitled CoPAS: Collaboration Patterns Agent Simulation. CoPAS is a simulation study carried out with the Wizard of Oz technique. Students used a groupware system, TeamWave Workplace, to solve a learning task in the domain of object-oriented analysis and design us...
متن کاملNew Media Collaboration through Wizard-of-Oz Simulations
The “Wizard of Oz” (WOz) method for supporting the evaluation of incomplete computer prototypes derives from the early days of the human-computer interaction community [5], and has subsequently been utilized by hundreds of researchers and designers to emulate technologies in interactive media systems [1,2]. Despite its popularity, we believe opportunities exist for expanding the method’s use th...
متن کاملImpact of Online Setting Collaboration through Strategy-Based Instruction on EFL Learners’ Self-efficacy and Oral Skills
This study aimed to investigate the impact of web-based cooperative teaching through strategy-based instruction on EFL learners’ speaking and listening skills. Moreover, the use of cooperative teaching was hypothesized to have impact on the EFL learners’ self-efficacy. To this purpose, the study followed a mixed-methods design by implementing both qualitative and quantitative data gathering pro...
متن کاملExtending a virtual chemistry laboratory with a collaboration script to promote conceptual learning
We developed collaborative extensions to ‘Vlab’, a web-based laboratory that supports students in conducting virtual chemistry experiments. While results from a recent study indicated that VLab promotes chemistry learning, they also revealed that there is room for improvement. We embedded VLab into a collaborative environment that implements a computer-supported collaboration script for guiding...
