Research also shows that video doesn&#8217;t consistently outperform reading or other teaching methods, so educators should consider what students need to learn before choosing a format. Effective educational videos use visuals to explain relevant information, organize material into manageable sections, and give students opportunities to apply what they&#8217;ve learned. With Visla, educators can turn existing teaching materials and recordings into instructional videos that they can edit and refine.<\/p>\n<\/div>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Are Educational Videos Effective?

They aren&#8217;t percentages of information retained. The two results also come from different sets of comparisons, rather than an experiment directly testing replacement against supplementation. Adding a video may provide students with additional instructional time, alternative explanations, or opportunities to review material, all of which can contribute to better outcomes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The effectiveness of video also varies with what students are learning. In a <a href=\"https:\/\/doi.org\/10.1016\/j.compedu.2020.104034\" target=\"_blank\" rel=\"noreferrer noopener\">2021 experiment involving 247 undergraduates<\/a>, researchers assigned students to learn about stem cells through written text, video, or subtitled video. All three groups performed similarly on immediate comprehension questions. For that particular material, choosing video over text didn&#8217;t produce a measurable advantage in immediate understanding. Taken together, these studies give educators good reason to use video while also considering how well the format serves a particular lesson.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When should educators use videos?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Video is especially useful for teaching procedures where timing, movement, and the order of actions matter. Consider an instructor teaching students to use a laboratory micropipette. The demonstration needs to show exactly when to press the plunger to its first stop, how slowly to release it while drawing liquid, and when to press through the second stop to dispense the remaining liquid. A close-up recording lets students observe the instructor&#8217;s finger movements and the pipette tip at each stage. Those details are considerably harder to reconstruct from a few photographs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There&#8217;s research supporting the instructional value of showing motion. A <a href=\"https:\/\/doi.org\/10.1016\/j.learninstruc.2007.09.013\" target=\"_blank\" rel=\"noreferrer noopener\">meta-analysis of 26 studies published in <em>Learning and Instruction<\/em><\/a> compared animated instructional visuals with static pictures. Across the studies, dynamic visuals produced better average learning outcomes, with particularly substantial benefits when learners were acquiring procedural-motor knowledge. The comparison was between moving and static representations, rather than between video and every other teaching format. Still, it provides a useful basis for understanding why a recorded demonstration can communicate information that individual images leave out.<\/p>\n\n\n\n<!-- Visla research visual: H\u00f6ffler

class=\"wp-block-paragraph\">Animations can also help educators explain processes that students cannot easily observe firsthand. For example, an animation of pulmonary circulation could follow blood as it leaves the right ventricle, travels through the pulmonary arteries, exchanges gases in the lungs, and returns through the pulmonary veins to the left atrium. Showing the route progressively helps students connect the heart&#8217;s structures with the direction of blood flow. Each visual change communicates something about the underlying process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other lessons benefit from having a reference students can consult quickly. A written grading rubric lets students compare requirements while working on an assignment. A laboratory safety checklist can sit beside the equipment while students perform a procedure. An instructor might introduce the procedure through video, then provide the checklist for students to follow independently. Choosing between these formats depends on when and how learners need the information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to design an effective educational video<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Begin with a specific learning objective. Suppose you&#8217;re creating the pulmonary circulation video mentioned above. Instead of planning to cover the cardiovascular system generally, define what students should be able to do afterward: trace the path of blood from the right ventricle to the left atrium, identify the major vessels along that route, and explain what happens in the lungs. That objective gives you a clear way to judge which information belongs in the video. Detailed explanations of the heart&#8217;s electrical conduction system, for example, would add complexity without helping students accomplish this particular task.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once you&#8217;ve established the objective, plan how the visuals and narration will work together. You could divide the circulation lesson into three scenes. The first follows blood from the right ventricle through the pulmonary arteries. The second shows gas exchange in the lungs. The third traces the return through the pulmonary veins to the left atrium. As the narration names each structure, the corresponding part of the diagram can be highlighted. Students can follow the route without having to search an illustration crowded with labels.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A <a href=\"https:\/\/doi.org\/10.14742\/ajet.7296\" target=\"_blank\" rel=\"noreferrer noopener\">2022 systematic review examining 113 papers on instructional video design<\/a> found evidence supporting several principles relevant to this approach, including segmenting explanations, eliminating unrelated material, and giving learners control over playback. Together, these principles help students concentrate on the information they&#8217;re trying to understand. A diagram that introduces labels as they&#8217;re discussed, for instance, reduces the need to divide attention between the narration and several competing visual elements. Clear captions and descriptions of visually important information also help make the explanation accessible.<\/p>\n\n\n\n<!-- Visla research visual: Fyfield et al.

After demonstrating proper micropipette technique, an instructor could show a short clip in which someone presses the plunger all the way to the second stop before drawing liquid. Students would identify the mistake, explain why it could produce an incorrect volume, and describe the correct procedure. That exercise asks them to recognize and diagnose an error using what they&#8217;ve learned.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The exercise could appear as a question within the video, a classroom discussion, or a practical assessment. What matters is that students have an opportunity to demonstrate their understanding and receive feedback.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to make educational videos with Visla<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once you&#8217;ve planned your lesson, <a href=\"https:\/\/www.visla.us\/ai-video-agent\">Visla&#8217;s AI Video Agent<\/a> can help turn your materials into a video. Suppose you&#8217;ve already prepared a PowerPoint presentation explaining pulmonary circulation, complete with diagrams and an approved narration script. You can use the presentation as source material and provide the script to guide the video. Visla can organize the content into scenes, generate narration when needed, and assemble an editable draft. If the script is already finished, you can instruct the AI Video Agent to use it without rewriting your copy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For software tutorials, <a href=\"https:\/\/www.visla.us\/step-recorder\">Visla&#8217;s Screen Step Recorder<\/a> offers a different starting point. Imagine showing students how to submit a laboratory report through their learning platform. You could record yourself opening the assignment, attaching the correct file, submitting it, and checking that the submission was confirmed. Visla captures the on-screen actions and organizes them into instructional scenes with text overlays and optional narration. Students can then see the actual sequence of actions they&#8217;ll need to perform.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can refine either type of video using <a href=\"https:\/\/www.visla.us\/scene-based-video-editing\">Visla&#8217;s Scene-Based Editor<\/a>. Rearrange scenes, adjust their timing, replace irrelevant footage, and correct narration or subtitles. For the circulation lesson, check that every highlighted vessel matches the narration and that students have enough time to follow each stage of the route. For the software tutorial, remove unnecessary navigation and make the final submission confirmation easy to recognize.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After reviewing the finished video for accuracy and accessibility, share it with students as part of the lesson. The pulmonary circulation video could accompany an unlabeled diagram that students complete independently. The software tutorial could lead into an assignment where students upload a practice file and verify that their submission went through. Those activities give educators something concrete to assess while helping students put the video&#8217;s instructions to use.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/app.visla.us\/signup\" target=\"_blank\" rel=\"noopener\">Use Visla to make a training video<\/a><\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Quick Answer: Yes, educational videos can improve learning, particularly when they supplement existing instruction.
