Conducting Power Analyses to Determine Sample Sizes in Quantitative Research: A Primer for Technology Education Researchers Using Common Statistical Tests

摘要

The Journal of Technology Education is an international platform for scholarly discussion intended to advance thinking on technology and engineering education philosophy, theory, and practice. To this end, the journal publishes peer-reviewed research, theoretical, and positional articles addressing topics related to the PK-12 curricular area of technology and engineering education (T&EE), and its teacher education. The implementation of PK-12 T&EE promotes learning of both content and practice through student engagement in minds-on/hands-on, design based, problem-solving experiences. T&EE is a subject area fostering technological and engineering literacy where students learn about the full range of technologies from material processing, energy, biotechnologies, and robotics to construction, transportation, communications, electronics, and computational technologies. As a PK-12 curricular area, T&EE is intended for all students, regardless of their future career aspirations.
