The academic use of mobile technology engages students beyond traditional classroom contexts. Over the past few years, higher education institutions have promoted students’ learning and growth by supporting their use of mobile technology. Mobile technology offers educational possibilities that can enhance students’ growth in higher education. The aim of this study is to examine the relationship between college students’ academic use of mobile technology and higher-order thinking skills through their active engagement and learning effort. The sample consisted of 456 students at a university in South Korea, and the data were analyzed using partial least squares structural equation modeling. The results suggest that the academic use of mobile technology influences students’ higher-order thinking skills directly, in addition to their learning effort and active engagement in courses. These findings provide valuable information for higher education institutions that seek to introduce interactive and technology-integrated environments.

A significant temperature inversion with temperature differences larger than 3°C was observed in the southeastern Yellow Sea (YS) during February 2016. By analyzing in situ hydrographic profiles and results from a regional ocean model for the YS, this study examines the spatiotemporal evolution of the temperature inversion and its connection with wind‐induced currents in winter. Observations reveal that in winter, when the northwesterly wind prevails over the YS, the temperature inversion occurs largely at the frontal zone southwest of Korea where warm/saline water of a Kuroshio origin meets cold/fresh coastal water. Our model successfully captures the temperature inversion observed in the winter of 2016 and suggests a close relation between northwesterly wind bursts and the occurrence of the large inversion. In this respect, the strong northwesterly wind drove cold coastal water southward in the upper layer via Ekman transport, which pushed the water mass southward and increased the sea level slope in the frontal zone in southeastern YS. The intensified sea level slope propagated northward away from the frontal zone as a shelf wave, causing a northward upwind flow response along the YS trough in the lower layer, thereby resulting in the large temperature inversion. Diagnostic analysis of the momentum balance shows that the westward pressure gradient, which developed with shelf wave propagation along the YS trough, was balanced with the Coriolis force in accordance with the northward upwind current in and around the inversion area.
