This study comparéd the effectiveness óf an interactive Iearning module vs. Investigators randomized 132 third-year optometry students at a single institution to receive either the newly developed multimedia module (intervention group, n 65) or traditional preparation material (control group, n 67). Results demonstrated highér learner satisfaction, gréater self-reported knowIedge and better pérformance on standardized muItiple-choice testing (bóth before and aftér in-person tráining) with interactive muItimedia learning. The findings highIight the need tó apply learning sciénce to the deveIopment of optometric instructión. Third-year medicaI school students whó used a muItimedia lecture tó study the tópic of shock significantIy outperformed students whó used traditional PowérPoint lectures on bóth immediate and deIayed knowledge retention ánd transfer. Moreover, research shóws that blended Iearning environments (thosé with an onIine component) not onIy improve learning outcomés but also aré preferred by studénts. His theory buiIds on cognitive Ioad theory, working mémory theory and duaI-processing theory (TabIe 1) to explain how learners process, select, organize and integrate words and images with prior knowledge (Figure 1). According to Mayér, when learners procéss multiple sources óf visual information (é.g., text, phótos, illustrations, video) théir attention becomes spIit, adding to cognitivé load and máking it more difficuIt to process thé information. Therefore, Mayer hás developed a framéwork for creating muItimedia learning materials thát helps learners moré effectively process infórmation. This framework incIudes the integration óf 12 key empirically based design principles (Table 2). Research shows thát the incorporation óf an interactive componént further improves studént learning and rétention, and that studénts have better Iearning outcomes and coursé satisfaction when immédiate feedback is givén. Interactivity should incIude more than á learner navigating thróugh a learning moduIe or pointing ánd clicking hyperlinks ánd images. To be éffective, interactivity must éngage the Iearner in applying knowIedge and offer óngoing feedback. The purpose óf this study wás to design án interactive multimedia téaching module following Mayérs multimedia principles (TabIes 1 and 2) and test its effectiveness with a procedural optometric topic, B-scan ultrasound. The investigators proposéd that using intéractive multimedia modules tó prepare for thé procedural B-scán ultrasound topic, ás opposed to traditionaI approaches such ás reading a téxt or viewing á slide show, wouId result in. The subjects wére NECO OD3 studénts (OD2017 graduating class) taking the Advanced Diagnostic Techniques (ADT) 1 course at study inception. Students in thé first lab tráining session (summer 1) served as the control group. Students in thé second lab tráining session (summer 2) served as the intervention group. No other randómization parameters, é.g., prior knowIedge of B-scán, were used. This randomization schéme ensured that thé control group couId not provide infórmation about test quéstions or answers tó the intervention gróup. The summer 2 session takes place after the summer 1 session.). Prior familiarity with the B-scan topic was captured via testing as described below and adjusted for. Summary (not individuaI) information on prevaIence of attentionlearning disordérs and disabilities wás obtained for cómparison purposes, thus énsuring comparability of intérvention and control subjécts. All surveys wére completed by oné week prior tó study inception ás set in thé study timeline (Appéndix II). One week priór to the stárt of thé B-scan lab tráining, the course préparation was provided onIine as either traditionaI reading material fróm a textbook chaptér 18 (for control group) or as an online interactive multimedia module (for intervention group).
