Description and Purpose

During a Punctuated Lecture, students listen to the lecture for approximately twenty minutes. At the end of the lecture segment, the lecturer pauses and asks students to answer questions about what they are doing at that particular moment.

Punctuated Lectures help to promote student engagement during a lecture through the process of asking students to be more self-aware of their own involvement (Angelo & Cross, 1993). The activity also can help students refocus attention if their minds have wandered, which can help to improve active listening. Over time and with practice, students can develop skills as self-monitoring listeners. In short, Punctuated Lectures can help student develop metacognitive skills, or the ability to think about their own thinking and learning.

Punctuated Lectures also are a useful method of providing instructors with information about what learning strategies students use during the lecture. In turn, instructors can use the information to help guide students during lectures, such as directing students to attend to important content or reviewing a concept for understanding.

Preparation

  • Before deciding to use this Punctuated Lectures, consider exactly what you want to know, such as the following:
    • How much students were focused on the lecture content at a given point
    • How distracted students were by technology or by each other
    • What students were physically doing, whether listening or taking notes or doing something unrelated
  • Next consider your question format. You might ask students to respond to an item based on a scale (5 = extremely high, 1 = extremely low) with prompts such as “How would you describe your level of focus on the lecture?” “How would you describe your level of distraction from the lecture?” Or you also might ask an open-ended question such as “Describe what you were doing when the lecture paused.”
  • Finally, consider how you will have students respond. You might have them respond on an index card or you could use an automated response system (clickers) or an online survey.

Procedures

  1. Tell students that you will lecture and stop every so often to ask them to record what they are doing.
  2. Tell them how they should record their responses.
  3. Begin the first section of the lecture, which should last approximately fifteen to twenty minutes.
  4. Stop the lecture and ask students to think about what they were just doing.
  5. Ask students to answer the question(s) you have developed.
  6. Resume the lecture and repeat every fifteen to twenty minutes for the duration of the class.
Video Lecture Large Lecture
When lecturing through video online, stop the content portion of your lecture periodically and ask students to record what they are doing at that time. They can submit their work as a quiz during the lecture or as an assignment. For large lecture courses, consider developing a multiple-choice stem (e.g., 1. What is your current attention level for the lecture: a. very high, b. high, c. low, d. very low) and administering electronically through an automatic personal response system (clickers).

Examples

Nursing as a Profession (Lecture)

In this seminar course, the professor felt that students were always engaged when they were taking about their past experiences. However, the professor felt that the students “checked out” as soon as she started talking. She had important content to share, however. She didn't believe that the students had ill intentions; indeed, she didn't believe that they knew that they were checking out at all. She wanted to help them learn to self-monitor their own attention levels.

She decided to use a Punctuated Lecture. She told students that she had some information to share with them that would take roughly fifteen minutes and noted that she would be using a slide deck because some of the information was visual. She asked students to take notes on the information. About ten minutes into her lecture, she showed a slide that read “on a scale of 5 to 1, with 5 being the highest level and 1 being the lowest level, rate your current level of attention to the lecture.” She noted some uncomfortable shuffling as students began to look up and read the question. Several acknowledged after class that they had not been paying as much attention as they should have been and stated their determination to do better in the future.

Sociology (Large Lecture)

In this course on sociology, the professor believed that students were being distracted by personal technology. He noticed that some students were checking social media sites as well as their personal texts during class. He knew that this habit distracted them from learning and believed that it distracted other students around them. He decided to use Punctuated Lecture to help draw student attention to the issue. During a lecture on inequality and stratification by social class, he paused the lecture for a minute and asked students to use their clickers to respond to a series of items:

Because students responded with clickers, their responses were anonymous. He thought this anonymity coupled with the large class size allowed for fairly honest responses. He noted that most students believed that they were listening to the lecture and looking at the lecturer when the lecture paused; his visual scan of the room did not confirm this assessment, however, so although he believed they thought they were paying attention, their multitasking was contributing to a lack of self-awareness. A few students acknowledged checking social media and texts. However, many students noted that they were distracted by other students' technology.

The professor used his own assessment as well as the survey results as an opportunity to discuss the importance of paying attention to the lecture for learning and for course success. He also described some of the recent research on multitasking that suggests that it detracts from learning. Finally, he talked about course citizenship and reviewed the course policy on technology use during class.

He began to implement the activity regularly. He alerted students when it seemed that they had not accurately self-assessed, and he congratulated them when they had and when their attention seemed to be at high levels. He noticed improvement in attention and fewer technological distractions over time.

Microeconomics (Video Lecture)

The professor of this online microeconomics course used the Punctuated Lecture to help students pay attention to the course video lectures. During a lecture on pricing, he discussed the factors that went into developing the pricing of the iPod. At about ten minutes in, he asked students to stop the video and respond to a quiz in the learning management system (LMS). The quiz asked students to rate their level of engagement in the lecture on a scale of 5 to 1, with 5 being the highest and 1 being the lowest. He also asked students to reflect in their course journals on what they were doing during the lecture. He was surprised with several students' candor. Some reported caring for small children, others folding laundry, and others surfing the Internet. He sent a note to the class thanking them for their honest disclosures but also stressed the importance of giving full attention to the lecture. He continued using the activity and noted a decrease in reporting of distracting activities that coincided with an increase in quiz scores. These results helped him conclude that students were learning to better self-manage in his online course, and he shared this insight and the evidence of their improvement with them.

Variation and Extension

  • Ask students to journal their responses over time. Take up their journals to assess them periodically. This variation will enable them, and you, to see changes over time.

Observations and Advice

Students new to higher education may find this activity particularly beneficial because it teaches them self-monitoring, which is a skill that can help them in other courses as well. This activity can be effectively scaffolded. You can begin by using it at each class session and then reduce to using it during half of the class meetings. Also, you can start by breaking every fifteen to twenty minutes and move to longer lecture segments.
