This paper examines where students prefer to find information, and then matches survey results with students' assignments. Surveys showed that half the surveyed students used library databases (e.g. ProQuest) as their first preference to locate scientific information; however, of these students, one third did not have any journal articles cited in their assignment. Furthermore, of those students with no journal articles cited in their reference list, 65% claimed to feel comfortable using library databases, against a figure of 100% who felt comfortable using Google Scholar. This indicates a mismatch between students' expressed preferences and their actual ability to locate, evaluate, and include refereed journal articles in their assignments.

Background: In this study the implementation of screencasts (video of computer screen with voiceover) as a strategy to address the diversity in mathematical backgrounds of students undertaking a third year surveying unit in both on campus and in distance modes, was investigated. This cohort of students did not have strong mathematical backgrounds, either at high school or university level, a reflection of a national sector wide trend. Barrington (2009) reported between 1995 and 2007 the number of students in Australia studying the highest levels of mathematics in Year 12, Intermediate and Advanced mathematics, declined by 22% and 27%, respectively. Correspondingly, there was an increase of 30% in students studying Elementary mathematics, and this situation is often compounded by a lack of retention of mathematical concepts between high school and university (Jennings, 2009). Purpose: Identify the mathematical background of students enrolled in a third year surveying unit, then determine if screencasts are easy to use, help students understand mathematical concepts and are helpful for revision. Design/Method: To overcome the difficulty of teaching students with different levels of mathematical background screencasts were embedded into this unit from 2009. To determine the background mathematical level of the cohort and the effectiveness of this teaching strategy, each year students were asked to voluntarily participate in a questionnaire from 2009 to 2011, which included qualitative and four part Likert scale (strongly agree-disagree) questions. Results: Of the 53 students completing the questionnaire over three years, it was apparent the cohort included students with diverse educational background, as 25% had not completed the Higher School Certificate (or equivalent); 32% had studied mathematics at Year 12 Elementary level or School Certificate level; and 25% had studied mathematics at advanced Year 12 level. Screencasts were well received with 84% user rate; and of these students, 95% found screencasts easy to use, 98% found they made the steps in the calculation easy to follow and 93% found they were beneficial when studying for the quizzes and exam in the unit. Conclusions: Use of screencast in information literacy and computing has been previously investigated in the literature but it is poorly researched in mathematical concepts. In this case students found these resources easy to use and very helpful in assisting their understanding of mathematical concepts, especially for distance students.
