A surprisingly difficult but critically important part of designing a lesson is establishing the learning goals. Many teachers write learning goals in the form of behavioral outcomes: “Students will be able to…” Frequently this is what their administrators want, and sometimes it is what they were taught to do in their preservice training.

But learning in an academic context is a mental activity, and so learning goals for academic subjects should actually describe a desired internal change in the student. That is, at the end of a lesson, students should understand something new, should know something knew, or should feel differently about something. Their ability to *do* something new is a side effect of their new knowledge or understanding.

Articulating learning goals in this way helps you think more deeply about the contents you are trying to teach. To see how this is true, let’s try rephrasing a typical learning goal for 5th grade:

“Students will be able to add fractions with unlike denominators.”

Contrast the following possible learning goals, expressed as internal changes in the student, either of which would yield the same ability to add fractions correctly:

(A) The student knows that to add two fractions with different denominators, one needs to find the least common multiple of the two denominators, convert each fraction to an equivalent fraction with that least common multiple (called a ‘common denominator’), then add the numerators of the converted fractions, and write the result as (sum of numerators) / (common denominator).

vs.

(B) The student understands that, because the denominator of a fraction defines the size of the unit, fractions expressed using different units (e.g. fourths and thirds) must be converted to a common unit (e.g. twelfths) before they can be added. The student will realize that she can use her previous knowledge of equivalent fractions to rewrite the fractions with a common unit, and then add those fractions in the normal way. Students will realize that the idea of least common multiple can be used to find the smallest common unit.

Imagine a lesson designed around goal A vs. a lesson designed around goal B. After either lesson, a student should “be able to add fractions with unlike denominators”, but what that student would *know* is quite different.

Consider also how a student would *feel* after these lessons. At the end of a “goal A lesson”, the student might feel burdened with another procedure she has to remember and be careful to use in the right circumstances. After a “goal B lesson”, the student might feel a sense of power – she can use what she already knows to solve a new problem!

Finally, consider how you would *assess* students vis-à-vis these goals. A worksheet or quiz that asks students to add fractions with unlike denominators might tell you whether students know what to do, but won’t tell you if they understand why.

The point of this is not that goal B makes for a *better* lesson than goal A. The point is that goal B makes for a *different* lesson than goal A, which will have different effects on students, even though the same “students will be able to” statement would apply to both. Thus it important to think carefully about the cognitive (and affective) changes you want to create in your students before you design your instruction.

Key takeaway:Try writing your learning goals to describe what students will know or feel by the end of your lesson that is different from what they would know or feel at the beginning.

Thanks for this reminder! Appreciate the examples for clarity.

This is really helpful Tom, thank you. Great distinction between doing and developing deep understanding of mathematical structure.. i.e. learning.

I love think beyond the observable behaviors(I can statements) and identify the internal mental changes you wish to make in the students.

I am guilty as charged! I have written a plethora of learning goals in the form of behavioral outcomes. This new insight has definitely caused a shift in my way of thinking. Students will feel as sense of empowerment as they connect what they already know to new learning.

For 25 years I have and continue to look for observable behaviors in students’ learning. I am happy to have read this information to make me shift some of my thoughts around math practices. I see how important it is for students to think about their thinking and being able to explain their thinking and reasoning.

I think this is very helpful to have learning goals. To really be aware of what students will learn and be able to do after the lesson. Making the lesson concrete and measurable. I agree with allowing for looking at how lesson plans can vary and change the whole perspective and lesson as seen by A vs B.

Very interesting concepts…I will make this adjustment and see what happens with my students

This is wonderful information. Information such as this is extremely helpful for teachers in order to created lessons that are meaningful and deep

I agree with the article. The way we structure our statement could have a profound affect on how student view the problems and their deep understanding of the topic . the B statement allows students to scaffold the new learning into what they should already know more easily.

This is very helpful especially after the pandemic when students’ emotional needs are very important in their learning.
