This article aims to provide an overview of the opportunities for developing computational thinking in young learners. It includes a review of empirical studies on the educational technologies used to develop computational thinking in young learners, and analyses and descriptions of a selection of commercially available technologies for developing computational thinking in young learners. The challenges and implications of using these technologies are also discussed.

Adopting a mixed-method research design, this exploratory study examined the effectiveness of smartphone-based, AR artifact creation and other mobile collaborative learning activities in reinforcing the technological pedagogical content knowledge (TPACK) of teacher education students. The study indicated that mobile AR artifact creation with peer discussion tended to better promote the componential competencies of technological pedagogical knowledge (TPK) and the integrative development of technological pedagogical content knowledge (TPACK), whereas mobile media artifact viewing with peer discussion seemed to better support the content knowledge (CK) development.

The application of quantitative techniques in the analysis of highly cited articles can improve the researchers' understanding of the directions in health care sciences and services field. Y-index is useful for the evaluation of contributing authors.
