Policy emphases on early childhood and elementary computer science education have led to the development of many developmentally appropriate computer science and robotics tools, pedagogies, and high-quality curricula. One example is the integrated Coding as Another Language pedagogy for coding, literacy, and social and emotional learning. The…

With the growing popularity of computational thinking (CT) classes in K-12 schools, it is important to investigate public perceptions of these initiatives. Analyzing public discussions and opinions provides valuable insights that can inform future educational policies and reforms. In this paper, we collected questions and answers related to CT…

This literature review synthesized current research on preservice and in-service programs that improve K-6 teachers' attitudes, self-efficacy, or knowledge to teach computing, coding, or computational thinking. A review of current computing training for elementary teachers revealed 21 studies: 12 involving preservice teachers and nine involving…

The perspective that computing and computational thinking (CT) are necessary competencies for the 21st century is increasingly pervasive. Computational concepts and methods--problem solving, designing systems, refining the steps in a process, and tinkering toward creative solutions--are relevant in nearly every discipline, profession, and…

Crowdsourcing is an emerging research area that has experienced rapid growth in the past few years. Although crowdsourcing has demonstrated its potential in numerous domains, several key challenges continue to hinder its application. One of the major challenges is quality control. How can crowdsourcing requesters effectively control the quality…
