The development of web-based technologies in recent decades has provided ready access to a wealth of on-line educational resources, and despite concerns that availability of on-line recorded lectures impacts on-campus attendance, we believe there needs to be more focus on the learning resources students engage with, along with why and how they use these resources. Our survey of first year science and mathematics students found that more than 80% of on-campus and off-campus students engaged with [greater than or equal to]75% of lectures by attending face-to-face and/or viewing on-line lectures. And when asked about their use of external resources, 80% of students reported using YouTube and/or Open Educational Resources, amongst other on-line resources, to provide increased understanding of content and to view worked problems. Knowing that a large percentage of students will seek out additional on-line resources, we conclude that ensuring all students have well developed on-line search skills and the ability to critically assess the quality of on-line resources are important contributions that teaching staff can make to student learning.
