Evidence-based teaching
How People Learn (Biology)3
We know How People Learn.1
There is research that informs us. Let’s exploit the patterns of learning to make instruction more effective.

How People Learn (Biology)
Scientifically Outdated, a Known Failure

We must abandon the tabula rasa “blank slate” and
“students as empty vessels” models of teaching and
learning.

How People Learn (Biology)
Constructivist theory of learning
11
New learning is based on pre-existing knowledge that you hold.
You store things in long term memory through a set of connections that are made with previous existing memories.
Higher-level learning = brain development
Physical changes occur inyour brain when you learn.

How People Learn (Biology)
Key Finding 1
13
Students come to the classroom with preconceptions about how the world works. If their initial understanding is not engaged, they may fail to grasp the new concepts and information that are taught, or they may learn them for the purposes of a test but revert to their preconceptions outside of the classroom.
How People Learn – Chapter 1, p 14.

How People Learn (Biology)
Key Finding 2
14
To develop competence in an area, students must:
a) have a deep foundation of factual knowledge,
b) understand facts and ideas in the context of a conceptual framework, and
c) organize knowledge in ways that facilitate retrieval and application.

How People Learn (Biology)
Key Finding 3
15
A “metacognitive” approach to instruction can help students learn to take control of their own learning by defining learning goals and monitoring their progress in achieving them. How People Learn – Chapter 1, p 18.
![Page 16: How People Learn (Biology edition)](https://reader033.vdocuments.us/reader033/viewer/2022061218/5481012cb4795979578b4810/html5/thumbnails/16.jpg)
Aside: metacognition
How People Learn (Biology)16
Metacognition refers to one’s knowledge concerning one’s own cognitive processes or anything related to them…. For example, I am engaging in metacognition if I notice that I am having more trouble learning A than B.

Implications for Teaching 2
28
Teachers must teach some subject matter in depth, providing many examples in which the same concept is at work and providing a firm foundation of factual knowledge.
Classroom Environments 2To provide a knowledge-centered environment, attention must be given to what is taught (information, subject matter), why it is taught (understanding), and what competence or mastery looks like.

Implications for Teaching 3
39
The teaching of metacognitive skills should be integrated into the curriculum in a variety of subject areas.
Classroom Environments 3Formative assessments — ongoing assessments designed to make students’ thinking visible to both teachers and students — are essential.Instructors need to provide
opportunities for students to practice being metacognitive –
thinking about their own thinking

Alternating with 10-15 minute mini-lectures, 1. Instructor poses a conceptually-
challengingmultiple-choice question.
2. Students think about question on their own.
3. Students vote for an answer using clickers, colored/ABCD voting cards,...
4. The instructor reacts, based on the distribution of votes.

In effective peer instruction students teach each other immediately,
while they may still hold or remembertheir novice misconceptions
students discuss the concepts in theirown (novice) language
the instructor finds out what the students know (and don’t know) and reacts
students learn and practice how to think, communicate like experts
