Computer-mediated communication as a vehicle for learning: Engaging with students online
Bibliographic record
Abstract
BACKGROUND Graduates of a Bachelor of Science must “be effective communicators of science by ... communicating scientific results, information, or arguments, to a range of audiences, for a range of purposes, and using a variety of modes” (Yates, Jones, & Kelder, 2011, p. 11). To achieve this outcome requires effective mechanisms for its assessment. AIMS The aim of this study was to investigate perception of an online communication tool used by first year undergraduate science students as part of an assessment task. This assessment task aimed to develop content and generic skills by using “…communication as a vehicle for learning” (Barrie, 2007, p. 456). DESIGN AND METHODS Students used Prezi, an online communication tool, as part of an assessment task in an introductory chemistry unit. This online modality replaced a face-to-face poster presentation; in the first semester volunteers were recruited, and in second semester all students were compelled to use Prezi. This task formed 10% of the final grade in this unit. Students were requested to construct a 5 to 10 minute Prezi presentation, and a short precis of their approach to this task. Students were provided with a chemical topic and target audience that their presentation should be aimed at, and peers and instructors assessed the outcomes. Student perception of this assessment task was measured with an established instrument (Maor & Fraser, 2005) and the possible effects of student age, gender and mode of study on perception were assessed. RESULTS The instrument used to survey students was found to function well, with no significant difference in response patterns between respondents in each semester. In exploring the measurement model items of interest relating to the ease of use of Prezi emerged indicating its general utility. Student age has a minor impact on their perception of the ease of use of Prezi, with students over the age of 21 finding the program more complex, challenging and therefore more engaging to use than students 21 years old or younger. Students provided positive feedback on the impact that Prezi had on their approach to the assessment task. There were issues with isolation caused by replacing a group task in a social environment, with an individual task in an online environment. CONCLUSIONS Students’ positive perceptions on the use of Prezi, regardless of whether they volunteered or were compelled to use the tool, strongly indicate its promise as a vehicle for learning through communication. Further work will focus on the effect Prezi has on student social engagement and motivation, and the role of age in perception. REFERENCES Barrie, S. C. (2007).

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
