Transition of the real world into the virtual world has been ongoing in online and on-ground classrooms and labs for many years. But the more the world goes virtual, the more difficult it becomes for those who are blind or visually impaired to participate fully in the learning process. The main thrust of this report is to explore how 3D printing and the use of conductive filament can begin to reverse that process by making 3D printed talking tactile learning objects that can generate audio when touched after being placed on the surface of an iPad or other tablet computer. Examples of talking tactile learning objects from STEAM (Science, Technology, Engineering, Arts and Math) disciplines will be presented with a focus on how the design of 3D printed STEAM learning objects can lead to a common learning object template model. The template can be designed to serve as a learning tool not only for a blind or visually impaired student but also can work as well for a sighted student or a teacher, aide or parent demonstrating how universal design principles can drive the learning object production process.

Retrieval practice is described as a pedagogy that includes ways that students have a chance to recall information during their study process. With the introduction of online learning and course management systems which permit secure testing online, a way is provided to generate many sets of small quizzes from large question pools which can serve as an efficient digital method for practicing recall of the information to be learned. Course management systems also provide a way to capture and store the results of the small quizzes used for retrieval practice. This study looks at data captured by taking numerous small quizzes as the retrieval learning process and compares the captured data sets to the grade distribution in the major exams for which the small quizzes are being used as a way to learn the material being tested. The overall results demonstrate that the use of retrieval practice does enhance student learning and also was found to lower the drop rate for the micro and macro anatomy courses studied.
