Student groups construct simple conductivity probes and then integrate them into two different circuits to test the probe behavior in solutions of varying conductivity (salt water, sugar water, distilled water, tap water). The activity culminates with student-designed experiments that utilize the constructed probes. The focus is to introduce students to the fabrication of the probe and expose them to two different ways to integrate the probe to obtain qualitative and quantitative measurements, while considering the application and utility of a conductivity probe within an engineering context. A provided handout guides teams through the process: background reading and questions; probe fabrication including soldering; probe testing and data gathering (including circuit creation on breadboard); probe connection to Arduino (including circuit creation and code entry) and a second round of testing and data gathering; design and conduct their own lab experiments that use the probes; online electrolyte/nonelectrolyte reading, short video, comprehension check and analysis questions.

Students investigate the difference between qualitative and quantitative measurements and observations. By describing objects both qualitatively and quantitatively, they learn that both types of information are required for complete descriptions. Students discuss the characteristics of many objects, demonstrating how engineers use both qualitative and quantitative information in product design.

This is an article from USA Today about the difference between Millenials (Gen Y) and prior age groups at work.  I share the article with students and ask them to highlight qualitative and quantitative data in different colors.See link below for a quick video explanation of how I use this in class.Qualitative vs Quantitative Data

This is a student handout that summarizes the differences between qualitative and quantitative data.See link below for a quick video about how I use this in my classroom.Qualitative vs Quantitative Data - Student Handout

This graduate seminar introduces an emerging research program within International Relations on territorial conflict. While scholars have recognized that territory has been one of the most frequent issues over which states go to war, territorial conflicts have only recently become the subject of systematic study. This course will examine why territorial conflicts arise in the first place, why some of these conflicts escalate to high levels of violence and why other territorial disputes reach settlement, thereby reducing the likelihood of war. Readings in the course draw upon political geography and history as well as qualitative and quantitative approaches to political science.
