Focus your attention for a moment on a recent class lesson you prepared and taught. First, think back to the steps you took to prepare. Next, consider what you and the students did during the class. Reflect on the ways in which the lesson design contributed to students' learning, and on any changes you're considering for the next time you teach the lesson. Then, think about whether this most recent class was typical or atypical in the ways you prepared and taught.

Lesson Design
We tend to invest much time and thought into preparing for our geoscience classes. As educators with multiple demands on our time, we probably could benefit from learning ways to prepare more efficiently. And, students definitely would benefit from us designing lessons that effectively and equitably furthered their learning. One approach is to design lessons that clearly communicate learning objectives, incorporate student preparation and prior knowledge, convey content in manageable portions, and provide opportunities for active learning, reflection, and assessment.

This approach to lesson design builds on insights from the scholarship on teaching and learning. This scholarship has validated the importance of creating active learning and reflection opportunities to allow students to practice the material they are learning through student participation, peer-to-peer interactions, and guided reflections (e.g. McConnell et al., 2017). These student-centered active learning approaches also promote inclusive environments for learning that encourage many students to participate (Tanner, 2013), increase student performance (Dang et al., 2018, Freeman et al., 2014; Yuretich et al., 2001), and reduce achievement gaps (Haak et al., 2011; Roberts et al., 2018). Furthermore, an increased structure that is clearly communicated and connected to overall course goals contributes to increased student learning and performance (Eddy & Hogan, 2014; Haak et al., 2011).

A lesson preparation approach developed for the biological sciences is the 5 E's learning cycle model that sequences a lesson to flow through five stages: 1) engagement, 2) exploration, 3) explanation, 4) elaboration, and 5) evaluation (Bybee et al., 2006; Tanner, 2010). A complementary approach that we developed for a session at the On the Cutting Edge/ NAGT Workshops for Early Career Geoscience Faculty starts with the lesson framework, considers student activities, assessment, and reflection, and concludes with the lesson plan. Guiding questions are included for each step.

Lesson Framework

  • Why is the topic important to the students or for society?
  • What are the learning goals for the lesson and how do they relate to the course goals?
  • What graph, figure, equation, or example is key for this lesson?
  • What prior knowledge is needed for this lesson.

Student Activity

  • What will the students do during class to further their learning?
  • How will they interact with their peers and with you?


  • How will you and the students be able to determine if they have met the learning goals?

Student Reflection

  • What opportunities will students have during the class to reflect on their learning?

Lesson Plan

  • Organize the lesson such that is has a beginning, middle, and end.
  • Decide how you will ask students to prepare based on the content or practice students they need to obtain before class.
  • Decide what you need to prepare. Slides? Handouts? Other materials?
  • Review the lesson to make sure that it flows, that it fits the time allotted, and that you have scaffolded the learning in ways that will support the application of more advanced skills and concepts.


Reviewing a Prepared Lesson
The Reformed Teaching Observation Protocol (RTOP) was developed as a way to evaluate instruction in science and mathematics classes and provide feedback to faculty (Lawson et al., 2002; Sawada et al., 2002). The RTOP has five categories of questions related to 1) lesson design and implementation, 2) the instructor's knowledge, 3) what students do, 4) student-student interactions, and 5) student-teacher relationships (Classroom Observation Project). In evaluating observations of geoscience classes, Teasdale et al. (2017) noted that the student-centered classes distinguish themselves in that "students engaged in class activities with one another," there were "activities in which instructors assess student learning and adjust lessons accordingly," or there were "opportunities for students to answer and pose questions that determine the focus of the lesson." We were inspired by the RTOP questions to write questions that would allow educators to review and revise their lesson plans before trying them. Eight questions for lesson review follow:

  • Is the framework clear to students? If not, then consider starting the lesson with the learning outcomes, a question of the day, an outline, or a concept map (see also Lang, 2016a for further suggestions).
  • Does the lesson use or assess students' prior knowledge? Consider using what students were asked to do in preparation for the class, students' life experiences, previous lessons, or a ConceptTest.
  • Is there an activity that allows students to explore or investigate (i.e. be a geoscientist)? At one or more points during the class, consider asking students to predict, hypothesize, assess, represent data, or interpret data.
  • Will students interact with each other about course content? If not, or if they always interact in the same way every class, consider incorporating a think-pair-share, gallery tour, jigsaw, case study, or discussion (see also McConnell et al., 2016 for further suggestions).
  • Will you have an opportunity to listen to students? Listening to students may take the often-used form of posing a question and hearing responses, or may include other ways of "listening" such as reading student responses to a discussion thread, looking at students' small-group work on the board, listening to group discussions, or reviewing graphs and sketches (see also Tanner, 2013 for further suggestions)
  • Are students asked to reflect on their learning? Consider asking students to write a minute paper, respond to a "how do you know" question, complete a knowledge survey, or construct a Concept Map (see also Lang, 2016b for further suggestions).
  • Does the lesson incorporate aspects that students have noted contribute to their learning and avoid aspects that students have noted impede their learning? You may learn of these through conversations, mid-course questionnaires, student evaluations and other forms of feedback.
