Engineering design provides students with an authentic context to apply science and mathematics to solving problems and motivates them to learn science, technology, engineering, and mathematics (STEM) subjects. Thus, teachers need to experience and become familiar with engineering design. However, little is known about how preservice teachers…

Analogical reasoning is considered to be a critical cognitive skill in programming. However, it has been rarely studied in a block-based programming context, especially involving both virtual and physical objects. In this multi-case study, we examined how novice programming learners majoring in early childhood education used analogical reasoning…

Tinkering is often viewed as arbitrary practice that should be avoided. However, tinkering can be performed as part of a sound reasoning process. In this ethnomethodological study, we investigated tinkering as a reasoning process that construes logical inferences. This is a new asset-based approach that can be applied in computer science…

We developed RoboSTEM, a portal for open educational resources for the use of robotics in teaching and learning, to help teachers learn how to design and implement lessons using robotics. In this article, the design and functionality of RoboSTEM and the theoretical foundations behind its design are described. Two usability testing studies are also…

In this study, we investigated the debugging process that early childhood preservice teachers used during block-based programing. Its purpose was to provide insights into how to prepare early childhood teachers to integrate computer science into instruction. This study reports the types of errors that early childhood preservice teachers commonly…

This qualitative study examined how preservice elementary teachers integrated robotics into science, technology, engineering, and mathematics (STEM) lesson designs and why they designed their lessons in a particular way. Participants' lesson designs were collected, and semistructured interviews were conducted. The authors analyzed lesson designs…

Robotics is conducive to STEM learning. However, teachers are not prepared to integrate robotics into teaching STEM. Additionally, technology in general is used to transmit knowledge to support student learning from technology. To achieve meaningful learning outcomes, students need to use technology as a cognitive tool and learn with technology.…
