Till AIED konferensen 15th International Conference on Artificial Intelligence in Education, in Auckland, Nya Zeeland, presenterade Annika Silvervarg (Linköping Universitet) och kollegorna Lena Pareto, Magnus Haake, Thomas Strandberg samt Agneta Gulz (Lund Universitet) följande artikel 2011: An Educational Math Game with a Teachable Agent and a Social Chat (eftersom artikeln publiceras internationellt, är den på engelska.)
Abstrakt: We present an educational math game, including a teachable agent and a social chat, that trains basic arithmetic skills with a focus on grounding base-ten concepts in spatial representations. It employs a board-game design with a variety of different sub-games, game modes and levels of difficulty. [...] In other words, the basic game with the TA contains a form of on-task conversation between agent and student. But the game architecture also has been extended with a chat where the student can engage in conversation with the TA, writing freely by means of the keyboard and bring up basically any topic in a chat-like manner. [...] One reason to include off-task conversation is to enrich the game and its motivational qualities for the age group in question (12-14 year olds). Another is to be able to explore whether such a conversational module can enable pedagogical interventions, such as supporting pupils math self efficacy and change negative attitudes toward math in general. » Läs mer

Till AIED konferensen 15th International Conference on Artificial Intelligence in Education, in Auckland, Nya Zeeland, presenterade kollegan Björn Sjödén tillsammans med Lena Pareto, Betty Tärning samt Agneta Gulz (Lund Universitet) följande artikel 2011: Transferring Teaching to Testing – An Unexplored Aspect of Teachable Agents (eftersom artikeln publiceras internationellt, är den på engelska.)
Abstrakt: The present study examined whether socio-motivational effects from working with a Teachable Agent (TA) might transfer from the formative learning phase to a summative test situation. Forty-nine students (9-10 years old) performed a digital pretest of math skills, then played a TA-based educational math game in school over a period of eight weeks. Thereafter, the students were divided into two groups, matched according to their pretest scores, and randomly assigned one of two posttest conditions: either with the TA present, or without the TA. Results showed that low-performers on the pretest improved significantly more on the posttest than did high-performers, but only when tested with the TA. We reason that low-performers might be more susceptible to a supportive social context – as provided by their TA – for performing well in a test situation. » Läs mer

Abstrakt: A teachable-agent arithmetic game is presented and evaluated in terms of student performance, attitude and self-efficacy. An experimental pre-post study design was used, enrolling 153 3rd and 5th grade students in Sweden. The playing group showed significantly larger gains in math performance and self-efficacy beliefs, but not in general attitude towards math, than the control groups. The contributions in relation to previous work include a new educational game being evaluated, and an emphasis on self-efficacy in the study as a strong predictor of math achievements. » Läs mer
