Although undergraduate research experience has proven to have positive effects on student outcomes, such opportunities are not always widely available. Options can be especially limited for early-career engineering students who have limited research experience. One approach to addressing this issue is to partner engineering instructors with active…

Students in introductory college science courses often have a simplified understanding of the scientific method. To introduce students to the complexity of the scientific process and the value of empirical observations, I implemented a semester-long assignment that required introductory-level college science students to build and calibrate weather…

Describes a micromanipulator that is inexpensive, simple to build, rugged, and capable of several modes of operation beyond those of other types. It can, for example, be used with its controls quite remote from the tool holder and microscope or be controlled by computer. (JN)
