This work builds upon prior work in developing robust concept inventories and skill assessments for statics instruction. While these instruments provide valuable tools to instructors to assess student progress, there is still need for learning materials to scaffold student learning from disconnected procedural and conceptual knowledge, to more holistic metacognitive knowledge. This study presents a multi-dimensional taxonomy for student use in solving statics problems. This taxonomy was created on the basis of Steif and Dantzelr’s (2005) Concept Assessment Tool for Statics and Danielson and Hink’s (2008) Statics Skills Inventory. The purpose of the taxonomy to force students to think about characteristics of the system, characteristics of the problem, and specific known and unknown components within the system before they begin to work on an appropriate solution. This two-part study used a quasi-experimental design. In the first phase of the study, six students worked individually to solve a set of statics problems under three conditions: 1) no additional prompts, 2) a controlled prompt where only the correct classification terminology was given, and 3) an open prompt where the the full taxonomy chart was given. In the second phase of the study six sets of students worked in dyads to solve the same statics problems under the same three conditions. This is a work in progress, due to be completed early December 2017. The results will be analyzed quantitatively to establish a percent correct, and will also be analyzed qualitatively to identify and categorize what mistakes were made and under what conditions. We expect groups with the taxonomic classifications to score better than the control groups. We expect the results of this paper to be useful to instructors of Statics courses who wish to better scaffold student learning and bridge the gaps between their procedural and conceptual knowledge.
