Description¶
A Betty's Brain teachable-agent software variant developed by Doris B. Chin and colleagues in which elementary students construct concept maps to teach an agent hierarchical scientific reasoning.
Components¶
- Hierarchical task model of open-ended learning environment tasks: The paper presents a hierarchical model characterizing the tasks students must perform to succeed in open-ended learning environments such as Betty's Brain, organized as "three broad classes of OELE tasks related to: (i) information seeking and acquisition, (ii) solution construction and refinement, and (iii) solution assessment." Each category is broken into three levels: general task descriptions common across OELEs, Betty's Brain specific instantiations, and system interface features. Directed links represent dependency relations, e.g., solution assessment depends on interpreting quiz results as actionable information for refining the solution in progress. (Gautam Biswas et al. (2016))
Claims¶
- Adding a teachable agent to the standard science curriculum improved fourth-graders' learning gains on both curriculum tests and researcher-designed hierarchical reasoning tests [+M]
- Kit+TA students spontaneously transferred the TA's hierarchical spatial organization to open-ended post-test answers, unlike Kit-Only students [+M]
- Classroom use of Betty's Brain showed a performance dichotomy: one study found 18 of 40 students made very little progress teaching Betty, while 16 taught a correct or nearly correct map. [+M]
