QuEST develops and researches practices in precollege quantum science and computing instruction that are aligned with the Next Generation Science Standards. The goals include the development of (1) quantum knowledge and quantum computing practices that promote critical thinking, reasoning, and communication skills; and (2) student awareness and interest in quantum computing careers and academic pathways. Strategies include onsite school day activities and summer camps in quantum science disciplines for diverse groups of students (QuEST Lab). In QuEST Lab, quantum science conceptual learning and quantum computing laboratory experiences relate physical science principles to modern technological advances, which enhance students’ knowledge, skills, sociocognitive domains, STEM career interests, and intentional academic behaviors. EduQation is a science teacher professional development program in quantum science principles and applications; this results in a multiplicative effect on student learning as these teachers implement quantum science and computing in formal physical science instruction. Science teachers improve their disciplinary content knowledge, ability to differentiate classical and quantum concepts, comprehension of technological advances in quantum industries, and understanding of how to educate students about quantum career pathways. These cognitive and affective outcomes have been measured by surveys, focus groups, and interviews with project participants; data were analyzed through inferential statistics and qualitative coding methods.
