While several existing computer-based learning environments include scaffolds like explanation construction tools, guiding questions, argumentation interfaces, workspaces for structuring tasks, data comparison tools, and tools for observing effects of plans made or models built, several of these scaffolds are part of the environment design and are not adaptive.
Some researchers define scaffolds as interface features (e.g., explanation construction tools; Reiser 2004).
Similarly, extraction of non-functional objects from the tool-dispensing apparatus (when food was present) would argue against rational planning being the explanation for tool-extraction during experimental conditions.

Specific details of the design and implementation of AXIOME are packaged with the source, including detailed explanations of tool development and the relationship between files in the repository.
Community feedback indicated privacy as a major concern especially regarding perceptions of non-participants, and that community acceptability required thorough explanation of study tools and procedures.
Specifically, officials should clearly communicate to at-risk persons the explanation that epidemiologic tools such as nasal swabs are poor indicators of past personal exposure and are, at best, indicators only of recent exposure.
