Video lectures and mobile learning devices have become prominent, but little is known about device choices for watching video lectures. The setting for this study, a university that provided perpetual access to personal computers and free tablet devices to all first-year students, provided a unique opportunity to study device choice in a setting where both tablets and personal computers were perpetually available. Weekly video lectures on a first-year module were made from October to April in two independent cohorts of students. YouTube analytics were used to record data on device usage for video lecture views. Tablets were initially used for almost 70% of views. However, tablet usage declined throughout the academic year, and tablets were overtaken by personal computers as the preferred device in the second half of the academic year. Findings suggest that an initial preference for using tablets to view video lectures lasts only a few months.

选择观看视频讲座的设备：对两个独立的一年级大学生群体的分析

视频讲座和移动学习设备已经变得非常重要，但是对于观看视频讲座的设备选择知之甚少。这项研究的背景是一所大学，它为所有一年级学生提供永久使用个人计算机和免费平板电脑设备的机会，这为平板电脑和个人计算机永久可用的环境中的设备选择提供了独特的学习机会。从10月至4月，在两个独立的学生小组中进行了关于一年级模块的每周视频讲座。YouTube分析用于记录观看视频的设备使用情况数据。最初使用平板电脑的观看次数接近70％。然而，平板电脑的使用率在整个学年都在下降，并且平板电脑在本学期的下半年被个人计算机取代，成为首选设备。
