This dissertation describes a practitioner's design-based development of a prototype chatbot to guide students in learning biological concepts of genetic mutations and protein synthesis. This chatbot's architecture provides learning activities, feedback, and support throughout a series of short, connected lessons. The chatbot is designed to…

Researchers have argued that a central goal of science education is to transform students' out-of-school experiences, so that students have aesthetic experiences of the world that would not otherwise be available to them. The goal of this paper is to articulate a set of design principles that support this goal. In doing so, I will first position…

Both those inside and outside of the education community are becoming increasingly familiar with the STEM acronym and the extensive efforts underway nationally to develop integrated PK-12 STEM programs that promote critical thinking, problem solving, 21st Century skill development and authentic learning experiences (Ingram, 2019). However, for…

Building on the work of teacher noticing, this study investigated teachers' noticing of students' thinking evident in artifacts from their science teaching context. Prior work on teachers' noticing in science has generally focused on noticing students' thinking surrounding specific disciplinary content. We asked 20 elementary teachers to identify…

We have conducted an education project to communicate the wave energy concept to high school students. A virtual reality system that combines both hardware and software is developed in this project to simulate the buoy-wave interaction. This first-of-its-kind wave energy unit is portable and physics-based, allowing students to conduct a number of…

Contribution: There are many on-line resources available to learn about optics and photonics, but no assessment tools exist to evaluate the learning achievements. This paper presents an assessment framework whose validity has been proven on a course with over 70 engineering students. Background: There is evidence that on-line resources complement…

Students are seldom given an authentic experience within school that allows them the opportunity to solve real-life complex engineering design problems that have meaning to their lives and/ or the greater society. They are often confined to learning environments that are limited by the restrictions set by course content for assessment purposes and…

The preponderance of the evidence from the engineering education literature demonstrates that inductive teaching methods are more effective than deductive approaches. When students are already familiar with the fundamentals of a topic, however, deductive approaches may make more sense. This paper discusses the implementation of a combination of…
