Teaching is commonly viewed as being teacher-centered.
Reinforced by the teaching evaluation process
Commonly reinforced by how we phrase course goals: “I want to expose my students to….” or “I want to teach my students that…” or “I want to show students that…”

“It dawned on me about two weeks into the first year that it was not teaching that was taking place in the classroom, but learning.”

We can’t do a student’s learning for him/her
Exposure does not guarantee learning Students learn when they are actively
engaged in practice, application, and problem-solving (NRC How People Learn).
If we are trying to decide what we want to accomplish in a course, shouldn’t we be asking what we want the students to be able to do as a results of having completed the course, rather than what the instructor will expose them to?

Could start by trying to develop list of topics that should be included in a geophysics course.
Misses the real point of a course Focus should not be on exposing students to topics.Focus should be on developing students’ abilities to tackle problems in geophysics

Example from a structural geo courseCourse focused on covered of the major topics in structural geology
Vs.Course focused on enabling students to make observations of rocks and thin sections and collect field data to evaluate the conditions of deformation and the deformation mechanisms responsible for structures and fabrics and, where possible, the history of deformation in a sequence of rocks.

Setting goalsSetting goals
Your course should enable your students, at appropriate level, to do what you do in your discipline, not just expose them to what you know.
Start by answering the question “What do I want my students to be able to do when they are done with my course?”

Why are the goals Why are the goals important?important?
If you want students to be good at something, they must practice;
therefore goals drive both course design and assessment
Task: Set one or two goals Task: Set one or two goals for a geophysics coursefor a geophysics course
Set goals for the students, not the professorStart with “Students will be able to…”Don’t use “I want to expose students to…” or “I want to show students that…”
Set higher-order thinking skills goalsUse verbs such as interpret, solve, predict, analyze, synthesize, construct, design, evaluate, formulate (higher order thinking skills)Avoid identify, classify, recognize, describe, calculate, list, explain, know about, have a strong background in (lower order thinking skills)

What general content topics could provide students background and practice in the tasks related to the goal?
Different approach than starting with a laundry list of topics to cover.

Goal: students will be able to make observations of rocks and thin sections and collect field data to evaluate the conditions of deformation and the deformation mechanisms responsible for structures and fabrics and, where possible, the history of deformation in a sequence of rocks.
Content to achieve goal: three case studies 1) brittle deformation features in rocks of Capitol Reef National Monument, 2) brittle and ductile deformation features of the Tethyan fold and thrust belt and the Gurla Mandhata metamorphic core complex in southwestern Tibet, and 3) a final, wrap-up case study with field trip in Precambrian and Lower Paleozoic deformed rocks northeast of Albany, NY.

Goal: students will be able to use data from recent Mars missions (Mars Express, Mars Exploration Rovers, and MOC and THEMIS images from the past year) to re-evaluate pre-2004 hypotheses about Mars geologic processes and geologic evolution.
Possible content topics to achieve the goals: 1) the origin of drainage networks on Mars, 2) the extent of intermediate to silicic rocks on Mars, and 3) the origin of layered rocks on Mars.

How about a different goal for the same hazards course?
Students should be able to evaluate and predict the influence of climate, hydrology, biology, and geology on the severity of a natural disaster.
Could we use the same content topics? Yes!

Content coverageContent coverage
Progression through content topics tends to be profoundly non-linear
Students learn what they need to know at any one time and re-visit content topics in increasing depth and breadth throughout the course.
Content coverageContent coverage
Do students need to know everything there is to know about each topic before they can do anything?? Nope!
Do students learn everything there is to know about each topic?? Nope!
Are either of these bad things? Nope! Depth in context of the goal vs. breadth

content knowledge that students must master to achieve the goal using that topic.

AssessmentAssessment
What students receive grades on must be tasks that allow you to evaluate whether students have met the course goals
Don’t assess what is easily measured – assess what you value.
Setting goalsSetting goals
Example from an art history courseSurvey of art from a particular time period
Vs.Enabling students to evaluate an unfamiliar work in its historical context or reconstruct an unfamiliar historical event from different viewpoints or a familiar historical event from a new viewpoint or seek out and evaluate information about an unfamiliar historical event
AssessmentAssessment
If students are graded largely on their abilities to recall, define, recognize, and follow cook-book steps, you have not evaluated their progress toward goals involving higher order thinking skills.

Goals-setting is hard but worth the effort Once the goals are set (provided that
they are specific, measurable, higher order thinking skills goals), the course and the assessment “falls together”

Authentic assessment is easy to integrate if goals are kept in mind
Workshop participants’ ideas about course design are completely transformed.
Participants report applying the same design principles to other courses and to department curricula.

Design model is goals-focused Terminology: goals vs. objectives vs.
outcomes vs. learning goals vs. learning objectives vs. learning outcomes
Geology faculty at our workshops largely not fluent in edu-speak
Some have encountered terms defined differently in different venues
Our workshop participants wasted time and energy coping with the distinctions

For our workshops, we collapsed goals, objectives and outcomes into one standard English term “goals”.
Goals for us will be concrete and measurable (“My goal in life is to make a million $$”; “My goal next year is to make the Olympic sock wrestling team.”)
Avoided “learning” as an adjective.

Easier to design a course when overarching goals are stated as specific, observable actions that students should be able to perform if they have mastered the content and skills of a course.

Setting overarching goalsSetting overarching goals
The overarching goals are the underpinning of your course and serve as the basis for developing activities to meet those goals.
There is no one right set of overarching goals for a particular course topic.
1-3 overarching goals is ideal.
