Making Room for Learning: Cognitive Load, Multimedia, and Agency in the Online Classroom

 

Introductory Note to the Reader      What I appreciate about courses like this one from ISTE+ASCD is their power to challenge what seems familiar. They can be groundbreaking because they encourage us to rethink what we believe we already understand about teaching. Giving students choices and freedom in their learning may sound straightforward, yet a closer look raises important questions: Are those choices meaningful? Do students have the support they need to make decisions? Does the lesson help them become more independent?      These questions invite changes in practice, and those changes deserve evaluation. Following the spirit of the ADDIE model, its final component, Evaluate, reminds us to examine whether our adjustments are helping students take greater ownership of their learning. Evaluation can also accompany implementation: listening to students, reviewing their work, and identifying what still needs attention. This essay grows out of that process of questioning, redesigning, and examining whether good intentions are becoming useful opportunities for student agency and learning independence.

Making Room for Learning: Cognitive Load, Multimedia, and Agency in the Online Classroom

	Abstract This reflective essay examines how cognitive load theory and multimedia learning principles can inform online English language teaching for college young adults and corporate working adults. Drawing on ISTE+ASCD course materials, the author’s reflections, and relevant scholarship, it considers how instructional decisions influence the demands placed on working memory. Particular attention is given to clear navigation, complementary words and images, meaningful segmentation, and the context-sensitive use of captions. A familiar TED Talk homework assignment provides the basis for a proposed redesign incorporating focused viewing sections, brief processing activities, learner control, and choices connected to relevant contexts. The discussion connects teacher agency in revising established routines with learner agency in managing and applying learning. It also distinguishes proposed benefits from demonstrated outcomes and identifies student work and feedback as evidence for future revision. The essay argues that meaningful agency requires clear expectations and manageable opportunities to make decisions.

Part II: From Intentional Choices to Manageable Learning

“The capacity to exercise control over the nature and quality of one's life is the essence of humanness.” — Albert Bandura (2001), Social Cognitive Theory: An Agentic Perspective, abstract.

“The question every design decision needs to answer is whether that demand is necessary for the learning or unrelated to it.” — ISTE+ASCD (n.d.), How Students Process, “Working Memory and Its Limits”

When a Good Resource Asks Too Much

An engaging video can still become a demanding assignment. A teacher may see an inspiring speaker and a worthwhile topic, while students face unfamiliar vocabulary, rapid speech, changing images, and questions to answer. The resource has educational value, but the conditions for learning need attention.

The earlier discussion, blog post #597, of agency and purposeful tool selection leads to a further question: can learners use the opportunities we offer when processing the lesson already consumes their attention? In my online teaching with college young adults and corporate working adults, this question makes lesson design a matter of professional responsibility. Meaningful choices need a manageable path through the learning.

Looking Beyond Student Effort

The ISTE+ASCD section “How Students Process” reminds teachers that working memory “can only hold and process a limited amount of new information at once” (ISTE+ASCD, n.d.-a, opening paragraph). This observation invites a different response when students struggle. Before assigning the difficulty entirely to preparation or motivation, we should examine what the task asks them to manage.

Sweller, van Merriënboer, and Paas (2019) explain that working memory is limited when processing unfamiliar information, while knowledge in long-term memory changes what learners can handle. The same assignment can therefore place different demands on students with different preparation. In language learning, knowing the topic does not necessarily mean understanding its presentation in English. A corporate learner may recognize the workplace problem immediately but struggle to follow the speaker’s explanation. A college student may understand individual words while losing the relationship between them. Both situations deserve instructional attention.

Recognizing Different Demands

The course distinguishes intrinsic, extraneous, and germane cognitive load. Intrinsic load concerns the complexity of the material in relation to the learner’s knowledge. Extraneous load involves demands that do not serve learning, such as confusing instructions or unnecessary movement between screens. Germane load describes effort directed toward understanding. In my personal course notes, I acknowledged, “I had never learned about the three different types of cognitive load in task design” (Acuña Solano, 2026, first reflection, sentence 1). Naming these demands helped me examine familiar teaching decisions more carefully.

The distinction needs one qualification. Sweller, van Merriënboer, and Paas (2019) describe germane load as resources devoted to handling intrinsic demands, rather than a separate load simply added to the other two. Segmentation can help manage essential complexity as well as unnecessary demands. The practical aim is to preserve effort for understanding, connecting, and using ideas.

Clarity as a Teaching Responsibility

The course recommends “clearly bounded chunks” and predictable navigation (ISTE+ASCD, n.d.-a, “Reducing Extraneous Load,” para. 1). These suggestions sound modest, yet they invite an honest inspection of the learner’s route. Imagine opening a lesson and finding the video in one location, instructions in another, and discussion questions in a separate document. Each component may be clear individually. Together, they require students to remember where to go and what to do next.

My proposed response is to place the objective, viewing sequence, and response instructions together. Each stage would explain its purpose and lead visibly to the next. For learners attending online after work or alongside university responsibilities, that clarity respects the attention they bring. It also makes the learning challenge easier to recognize.

Making Multimedia Serve Understanding

The course’s section “Multimedia That Works” emphasizes that words and images should do “different, complementary work” (ISTE+ASCD, n.d.-b, “How the Brain Processes Words and Images,” para. 1). An illustration should help explain something. Spoken commentary should help learners understand what they see. Mayer’s (2020) multimedia learning framework brings these decisions together. Coherence concerns removing irrelevant material; spatial contiguity places related words and images near each other; segmenting allows manageable stages; modality and redundancy address how spoken words, printed words, and visuals share limited processing capacity.

For my lessons, these principles suggest a practical question: what does this element contribute? A useful diagram may clarify a relationship that would require considerable explanation. A decorative picture may add little. A page filled with instructions, images, and text can look complete while making its central purpose difficult to find.

Revisiting the TED Talk Assignment

My clearest example comes from homework assigned to corporate adult learners. Although the textbook offered a segmented TED Talk activity, I asked students to watch the complete talk. Reflecting on that decision, I wrote that watching a lengthy talk “might not necessarily be a good idea” (Acuña Solano, 2026, second reflection, sentence 1). The concern is the relationship between the viewing demand and the intended outcome. A complete talk may serve extended listening or an overall argument. A focused excerpt may better support examining one claim. Neither choice can be justified by duration alone.

Brame (2016) recommends considering cognitive load, engagement, and active learning together when using educational video. Her review supports focused videos and purposeful questions. It does not establish a universal minute limit for every lesson. My course’s suggested three- or five-minute targets are useful planning prompts, rather than guarantees of comprehension.

Applying Principles With Judgment

My initial notes also treated several multimedia principles as already satisfied by TED Talks. That conclusion requires examining the particular recording. A speaker, slides, captions, music, and visual transitions can combine differently across talks. Professional production does not settle instructional suitability.

Captions deserve particular care in language education. Winke, Gass, & Sydorenko (2010) found benefits from captioning in foreign-language video activities, with differences across conditions. Their findings caution against treating all repeated spoken and written language as harmful. I would therefore retain access to captions when they support comprehension or accessibility, while helping learners decide how to use them. Some might listen first and consult captions during review; others may need them immediately. Applying a principle responsibly includes considering the learner and the purpose.

A Proposed Redesign With Agency

A revised TED Talk task could begin with a shared outcome: explain one central claim, support it with evidence from the talk, and discuss its relevance. This is a proposed improvement to my assignment; its classroom effects still need evaluation. Before viewing, students would see the outcome, three short guiding questions, and a small vocabulary preview. Only terms essential to understanding the selected passages would receive attention. Students could then choose an application: a university situation, a workplace situation, or another relevant context they can explain.

I would organize the viewing around three meaningful sections: the problem, the speaker’s response, and the implications. Each might last two to four minutes where the argument allows. A passage would end at a useful conceptual boundary, rather than at an arbitrary timestamp. Edpuzzle is the tool I identified in my reflections for developing this sequence. Its use would need to preserve a simple learner experience. The instructional improvement lies in the sequence and the decisions it supports.

From Viewing to Communication

After the first section, learners would state the problem in one sentence. After the second, they would identify evidence supporting the speaker’s response. After the third, they would explain one possible application or limitation. These pauses would invite processing without turning every moment into a quiz. For this reason, students would control replay and pause as far as the task permits. They could keep brief notes as keywords, a small diagram, or short sentences. A student who needs another viewing should have a clear opportunity to take it.

During the online class, pairs would compare their interpretations and agree on a recommendation. College students could connect the idea to campus life or a community concern. Corporate learners could use a fictional workplace situation. Partners would request clarification, examine the evidence, and explain why their recommendation follows from the talk. Shared assessment criteria would address understanding, relevant evidence, clear English, and interaction. Choice would influence the application and preparation while the learning expectations remained visible.

Agency Needs Support

Bandura (2001) connects agency with intentional action, forethought, self-regulation, and reflection. This perspective helps distinguish meaningful participation from simply choosing between options. In my redesigned task, learners would decide what context matters to them, monitor understanding, and explain their decisions. However, too many choices could create additional demands. I would begin with a few understandable options and allow an equivalent student proposal.

Teacher guidance remains important. Students need to know what successful participation involves before being asked to direct parts of it. My responsibility is to make that direction possible through preparation, clear expectations, and opportunities to ask for help.

Learning From the Next Version

The redesign would need evidence beyond completion records. I would examine whether students explain the claim accurately, use relevant evidence, and sustain the follow-up discussion. I would also ask which supports helped and where confusion remained. Stronger answers would not, by themselves, prove that segmentation caused improvement. Vocabulary support, prior knowledge, and practice could also contribute. Still, student work and feedback could guide the next revision.

This reflection has brought me back to a familiar lesson with a different way of seeing it. Teacher agency begins with questioning a routine; learner agency grows when the revised task offers purposeful decisions students can manage. Making room for learning means attending carefully to both.
