\u201cChemistry Bridge will allow digital resources to complement what I do one-on-one\u201d<\/p>\n
\u2014John Essigmann, Leitch Professor of Chemistry and Biological Engineering<\/div>\n<\/blockquote>\nThe opportunity:<\/h3>\n
Across the sciences, certain key concepts have traditionally proven challenging for students at all levels. These concepts are typically taught in introductory classes, but faculty must review them repeatedly in advanced classes across the curriculum. The Chemistry Bridge project is developing self-paced modules to assist mastery of these key concepts outside the classroom setting. The modules can be used independently by students, or as a faculty tool to supplement instruction.<\/p>\n
The project:<\/h3>\n
Students visit the Chemistry Bridge web site (currently under development) and take a \u201cpre-test\u201d to assess their understanding of the subtopics that constitute a core concept. Upon submitting their responses, students are presented with a \u201clearning pathway\u201d\u2014a curated set of web sites, videos and simulations that have been selected to address that student\u2019s learning goals. After completing the steps in the pathway, the student takes a \u201cpost-test\u201d to assess how well they understood the concept.<\/p>\n
Areas of innovation:<\/h3>\n
These modules are expected to advance teaching and learning at several levels:<\/p>\n
\n
- They provide a model and potential platform for creating self-paced, customized learning pathways that allow novice and advanced students to better understand and master key concepts.<\/li>\n
- They will improve efficiency by reducing the repetition of core concepts in advanced classes.<\/li>\n
- They promote community curation of a set of existing web-based teaching materials that best explain the concepts.<\/li>\n<\/ul>\n
Details:<\/h3>\n
The project is developing modules in the areas of:<\/p>\n
\n
- Buffers<\/li>\n
- Electrochemistry and Redox<\/li>\n
- Quantum Mechanics<\/li>\n<\/ul>\n
The key concepts are drawn from:<\/p>\n
\n
- 5.111 \u2013 Principles of Chemical Science<\/li>\n
- 5.12 \u2013 Organic Chemistry I<\/li>\n
- 5.60 \u2013 Thermodynamics and Kinetics<\/li>\n<\/ul>\n
Sustainability considerations:<\/h3>\n
The selection and creation of each new module initially requires a collaborative effort among faculty and domain experts to identify key concepts and their constituent subtopics.<\/p>\n
Populating each new module requires a set of informed content aggregators (the project is working with advanced MIT undergraduates) who curate the best online teaching materials.<\/p>\n
The tool that delivers the learning experience will require technical support and feature improvements to support evolving community needs.<\/p>\n
Future directions:<\/h3>\n
Although the tool is still under development, targeted for a Fall 2012 launch, the following future efforts have been identified:<\/p>\n
\n
- Feature refinements following usability testing with students.<\/li>\n
- Expanding the number of modules to include other key concepts.<\/li>\n
- Forming partnerships to implement the modules across Chemistry, and adapting the tool for use in other departments.<\/li>\n<\/ul>\n
