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. Jonathan

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. |

analiza cómo las decisiones didácticas influyen en las demandas sobre la
memoria de trabajo. Se presta especial atención a la navegación clara, la
complementariedad entre palabras e imágenes, la segmentación significativa y
el uso contextualizado de subtítulos. Una tarea habitual basada en una charla
TED sirve de punto de partida para proponer un rediseño con segmentos de
visualización, actividades breves de procesamiento, control del ritmo y
opciones vinculadas con contextos relevantes. La discusión relaciona la
agencia docente para revisar prácticas establecidas con la agencia del
estudiante para gestionar y aplicar su aprendizaje. Se distinguen los beneficios
previstos de los resultados comprobados y se proponen las producciones y

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.
