Pattern Analysis Of Genetics Animations Using Mayers Principles And Its Implications For MBBS Students

Background:MBBS students access online animation videos to understand complex concepts. However, multiple studies have raised concerns regarding quality of online educational videos. Animations designed using Mayer’s principles have been shown to improve learning outcomes.In this study, we analysedpattern and design qualityof online genetics animations using Mayer’s principles. Material And Methods:In this cross-sectional study, we analysed 59 online genetics animations chosen from MBBS 1styear Biochemistry syllabus. These animations were shortlisted through systematic search on www.google.comand www.youtube.com. These were analysed using Mayer’s multimedia learning principles that manage extraneous processing. Result:54% (33) of the animations complied with all the multimedia learning principles that manage extraneous processing. However, 44% (26) animations violated multimedia learning principles in various combinations. Amongst the animations that violated multiple principles, combination pattern of Signalling+Spatial Contiguity+Temporal Contiguity was most common (7 out of 26 animations). Conclusion:Majority of the animations follow all the Mayer’s multimedia principles that manage extraneous processing. However, significant portion of animations violated multimedia leaning principles in various combinations and their use may result in poor learning outcomes. By adopting a few easy to implement measures, teachers can increase their effectiveness as visual learning aids for MBBS students.

Analysis Of Design Of Online Animations In Biochemistry Using A Framework Based On Multimedia Learning Principles

Background:MBBS 1styear students access online animations in Biochemistry whichin turn helps them understand the rationale behinddiagnosis and management of diseases. However,there is a paucity of studies that have analysed online animations in Biochemistry based on Mayer’s Multimedia learning principles.Our objective was to analysethe design of freeonline animations in Biochemistry using a framework based on Multimedia Learning Principlesthat reduceextraneous processing.Material And Methods:In this cross-sectional study, design of 102 online Biochemistry animations was analysed using a framework based on Multimedia learning principlesthat reduce extraneous processing, and Focus Index (FI) score was calculated.Result:41.2 % of the animations had a FI score of less than 5, suggesting that these animations do not comply with all Multimedia learning principles.Animations violated individual principles in the range of 11 -17%. Conclusion:Significant proportion (41.2%) of online Biochemistry animationsdo not comply with all the Multimedia learning principles, suggesting that users of these animations may be distracted by extraneous content in the animationsleading to poor learning outcomes. Multimedia learning principles should be incor porated while designing animationsto enhance theirpotential as learning aids for MBBS students.

Efficacy of Multimedia Set on Acquisition Clinical Skills, Views of Medical Students in UMS.

Undergraduate training in Ear, Nose and Throat (ENT) surgery is often challenged by the short posting and limited patient contact. Multimedia is an useful tool in medical education to enhance clinical skills training. However, there is limited research on the development of such tools. We describe the development of an innovative multimedia set, where Mayer‘s principles for designing multimedia were followed in preparing an interactive CD-ROM. The developed set integrated basic sciences and clinical applications. The views of a sample of fourth year medical students and general practitioners were explored about the usefulness of this developed multimedia in facilitating the acquisition of clinical skills. The instructor led the live demonstration for the clinical examination. Then, students interacted with the multimedia set in a ratio of 4 students to 1 computer. Immediately afterwards, they practiced the technique of clinical examination of the nose. End of the session feedback revealed that most of the students found the innovative set had simplified the difficult techniques and rated it very good to excellent. Shortcomings in producing a perfect media tool are related to unavailability of media professionals in the institute. However, the prototype product was found effective in acquisition clinical skills and enhancing cognitive outcome. The continuous development of multimedia materials will improve the skills of the crew and the quality of the multimedia product.
