Is it more effective to take a 10-minute break halfway through a 90-minute lecture or a 90-second break every 10 minutes? Researchers investigated the effect of the timing of these breaks on learners in an undergraduate psychology course and have some interesting findings:

  • Students in the micro-break condition consistently outperformed those in the traditional break condition on end-of-session quiz scores.
  • Both groups showed decreases in performance over time (a typical vigilance or attention decline), but micro-breaks helped slow that decline, especially during the middle part of the session.
  • Traditional longer breaks produced a temporary boost only immediately after the break, whereas micro-breaks helped maintain a steadier level of performance.

The authors interpret these results using cognitive load theory and spaced learning principles—suggesting that short, frequent breaks help manage working memory and sustain attention better than a single long break.

It’s important to note that there were no delayed tests of knowledge, so we don’t know the effects on retention of knowledge, but this research is promising. Our minds naturally wander every few minutes, so building in these breaks throughout your learning activities encourages students to spend time thinking about the content they just encountered developing more elaborate memories.

Researchers in India conducted a randomized-control trial study with close to 17,000 at 10 colleges to test the impact of mandatory in-class phone collection versus unrestricted phone use. What do you think they found?

  • The was a small but statistically significant increase in grades (0.086 SD).
  • Effects were strongest for lower-achieving students, first-year students, and non-STEM majors.
  • Students who experienced the benefits became more supportive of cell phone bans.

So, what does this mean for you? This report is a pre-print and has not yet undergone peer-review, and it is just one study. However, the sample size is large, and the findings are promising for supporting in-class phone collection policies. It’s worth discussing this with your students, particularly first-year students, to talk about the impact of distraction on learning. Just putting the phone away in their bags or setting it to silent does not provide the same relief from distraction as putting the phone in a box in the front of the classroom.

The Cognitive Challenges of Effective Teaching /ctl/the-cognitive-challenges-of-effective-teaching/ Wed, 19 Nov 2025 22:01:13 +0000 /ctl/?p=5329 Chew & Cerbin propose a research-based framework of nine interacting cognitive challenges that teachers must address in order to promote “optimal learning” rather than merely acceptable performance. They emphasize that teaching is not just delivering content but creating the conditions in which students learn. Each of the nine challenges represents a characteristic of how students think, learn, or struggle — the idea being that failure to address any one of these can undermine learning. The authors describe each challenge, provide examples, and suggest instructional strategies for mitigation.

Chew & Cerbin propose a research-based framework of nine interacting cognitive challenges that teachers must address in order to promote “optimal learning” rather than merely acceptable performance. They emphasize that teaching is not just delivering content but creating the conditions in which students learn. Each of the nine challenges represents a characteristic of how students think, learn, or struggle — the idea being that failure to address any one of these can undermine learning. The authors describe each challenge, provide examples, and suggest instructional strategies for mitigation.

The Nine Cognitive Challenges & Our Suggestions

  1. Cognitive Challenge: Student mental mindset — students’ attitudes, beliefs, expectations about the course, their ability, and value of the content.
    Our recommendation: Be intentional about student mindset: From day one, communicate clearly the value of the course, the relevance to students’ goals, and emphasize that ability can grow with effort (growth mindset). Setting this tone helps mitigate fixed-mindset beliefs and promotes belonging and self-efficacy.
  2. Cognitive Challenge: Metacognition and self-regulation — students’ ability to monitor their own learning, judge their understanding, regulate study behaviors.
    Our recommendation: Support metacognition and self-regulation: Rather than assume students will monitor their own learning, build-in scaffolds (like study plans, exam-wrappers, reflective prompts) that ask students to reflect on what they know, what they need to do, and how they will adjust.
  3. Cognitive Challenge: Student fear and mistrust — negative emotions, anxiety, and lack of trust in the instructor or course that interfere with learning.
    Our recommendation: Foster trust and reduce anxiety: Create an environment of openness and fairness; explicitly explain your course policies, offer supportive feedback, allow revision when possible, and express a genuine belief in student capability. For adult learners especially, acknowledge diverse backgrounds and potential anxieties about re-entry, prior experience, or balancing responsibilities.
  4. Cognitive Challenge: Insufficient prior knowledge — students may lack the necessary background or foundation to learn new content effectively.
    Our recommendation: Assess and build prior knowledge: Especially for adult learners who may have varied or interrupted educational backgrounds, assess what they bring and fill the gaps early. Low-stakes pre-quizzes, review tasks, or scaffolded assignments help ensure a more even starting line.
  5. Cognitive Challenge: Misconceptions — students may hold inaccurate or deeply entrenched beliefs that interfere with learning new concepts.
    Our recommendation: Expose and correct misconceptions: Don’t assume that prior knowledge is accurate. Use diagnostic tools, ask students to predict, observe, explain (POE) experiments, and explicitly challenge common misconceptions.
  6. Cognitive Challenge: Ineffective learning strategies — students may use study approaches that are inefficient or counter-productive (e.g., highlighting, rereading).
    Our recommendation: Teach effective learning strategies explicitly: Rather than assuming students know how to learn, model and embed strategies like retrieval practice, spaced practice, self-explanation, elaboration. This is especially useful for adult learners who may default to habits from earlier schooling.
  7. Cognitive Challenge: Transfer of learning — students often fail to apply what they’ve learned in one context to new or novel contexts (near/far transfer).
    Our recommendation: Design for transfer — not just for content mastery: Encourage students to apply concepts in new contexts. Use varied examples, encourage analogy, scaffold tasks that require application, and help students reflect on how what they learned in your class might connect beyond it (e.g., their workplace, future courses, real-world problems).
  8. Cognitive Challenge: Constraints of selective attention — students’ limited capacity to focus, susceptibility to distractions, multitasking issues.
    Our recommendation: Manage attention and minimize distractions: In online or in-person settings, pay attention to how easily students can become distracted or multitask. Use frequent re-orientation to topic, build in short breaks, keep one clear focus at a time, and design activities that require active engagement rather than passive listening.
  9. Cognitive Challenge: Constraints of mental effort and working memory — limits on how much new information students can process at once; cognitive overload.
    Our recommendation: Reduce cognitive load and structure information clearly: Recognize that students’ working memory is limited. Present material in manageable chunks, use advance organizers (outlines, conceptual roadmaps), use dual-modality (verbal + visual) thoughtfully, avoid “seductive details” that distract, and gradually build complexity as students’ automaticity grows.

This framework reminds us that there is no one “best method” for all students and all contexts. Effective teaching involves diagnosing which challenges are most relevant to your specific learners and adapting practices accordingly.

What was that? The impact of distracting noises on learning /ctl/what-was-that-the-impact-of-distracting-noises-on-learning/ Thu, 06 Nov 2025 17:20:46 +0000 /ctl/?p=4055

This study by Marko et al. (2026) explores how auditory distractions—especially those with semantic meaning—interfere with the retrieval of information from semantic memory. Across four experiments, the researchers compared how people recall related (automatic) versus unrelated (controlled) words while exposed to different types of background sounds, including meaningless noise, reversed speech, and meaningful words. The findings show that meaningful auditory distractors significantly disrupt memory retrieval, particularly in tasks requiring inhibitory control (e.g., when participants must avoid giving the most obvious word associations). The results support an interference-by-process mechanism rather than simple attention capture—meaning that interference arises because distractors activate overlapping concepts in the brain’s semantic network, not just because they grab attention. The authors propose an “activation-suppression” framework, in which effective retrieval depends on both automatic spreading activation and active inhibition to suppress irrelevant meanings.

Key takeaways for faculty:

  • Cognitive load and distraction: Meaningful background noise—like conversations or spoken words—can subtly but significantly impair students’ ability to retrieve and articulate information that requires active thinking or controlled recall.
  • Task type matters: Simple, automatic recall tasks are less affected by distractions than those that demand deliberate control or creative responses. Faculty designing assessments or discussions should consider the type of cognitive retrieval they are fostering.
  • Learning environment design: Minimizing semantic distractions (e.g., background speech in open classrooms or during online sessions) can improve focus, especially during higher-order reasoning tasks.
  • Support for inhibitory control: Instruction that helps students practice cognitive inhibition—such as mindfulness, focused-attention exercises, or structured reflection—may enhance their ability to resist interference and retrieve knowledge effectively.

Overall, the paper highlights how seemingly minor background language can interfere with complex thought, underscoring the importance of controlled, low-distraction environments for deep learning and assessment

When you share a YouTube video for learners, annoying ads can disrupt the viewing experience and detract from the valuable content you chose. While the video may contain useful information, these interruptions can break the flow of learning and distract from the material. You also can’t track whether they watched the video. Here are two effective solutions:

  1. Consider using Kaltura, the UMS video platform, to create, upload, manage, and share multimedia content without ads. You can also track clicks in My Media. Here is a quick video demonstration: .
  2. You can tell students about the free , which includes a built-in ad blocker to enhance their viewing experience.
