Generating and Testing Hypotheses
Enhance students’ understanding
of and ability to use knowledge by
engaging them in mental processes that involve
making and testing hypotheses.

Four Planning Questions for Instruction
What knowledge will students learn?
Which strategies will provide evidence that
students have learned that knowledge?
Which strategies will help students practice, review,
and apply that knowledge?
Which strategies will help students acquire and
integrate that knowledge?

Generating & Testing Hypotheses
![Page 9: Generating & Testing Hypotheses Research-Based Strategies for Increasing Student Achievement Compiled from: Classroom Instruction That Works! By: Robert](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e305503460f94b207e9/html5/thumbnails/9.jpg)
Generalizations from the Research on Generating & Testing Hypotheses
1. The generating and testing of hypotheses can be approached in an inductive or deductive manner.
2. Teachers should ask students to clearly explain their hypotheses and their conclusions.
![Page 10: Generating & Testing Hypotheses Research-Based Strategies for Increasing Student Achievement Compiled from: Classroom Instruction That Works! By: Robert](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e305503460f94b207e9/html5/thumbnails/10.jpg)
The Two Approaches
•Deductive Thinking
…..is the process of using a general rule to make a prediction.
•Inductive Thinking
….. is the process of drawing new conclusions based on information we know or are presented with.

Recommendations for Classroom Practice
1. Make sure students can explain their hypotheses and conclusions.
2. Use a variety of structured tasks to guide students through generating and testing hypotheses.
![Page 12: Generating & Testing Hypotheses Research-Based Strategies for Increasing Student Achievement Compiled from: Classroom Instruction That Works! By: Robert](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e305503460f94b207e9/html5/thumbnails/12.jpg)
Recommendation # 2Use a variety of structured tasks to
guide students through generating and testing hypotheses.
• Decision Making
• Problem Solving
• Invention
• Experimental Inquiry
• Historical Investigation
![Page 13: Generating & Testing Hypotheses Research-Based Strategies for Increasing Student Achievement Compiled from: Classroom Instruction That Works! By: Robert](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e305503460f94b207e9/html5/thumbnails/13.jpg)
Recommendation # 1Make sure students can explain their
hypotheses and conclusions.
1. Provide students a set of steps for the task.
2. Use familiar content to teach the students the steps in the process.
3. Use graphic organizers to record information when carrying out the process.

Decision Making:
~ is about choosing an option around a decision that needs to be made and examining criteria and alternatives related to that decision.
![Page 15: Generating & Testing Hypotheses Research-Based Strategies for Increasing Student Achievement Compiled from: Classroom Instruction That Works! By: Robert](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e305503460f94b207e9/html5/thumbnails/15.jpg)
Problem Solving:
~ is about removing constraints or barriers to find the best solution to an unstructured problem.
![Page 16: Generating & Testing Hypotheses Research-Based Strategies for Increasing Student Achievement Compiled from: Classroom Instruction That Works! By: Robert](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e305503460f94b207e9/html5/thumbnails/16.jpg)
Invention:
~ involves creating something to fit a need or to improve upon something that already exists in order to make it better.
![Page 17: Generating & Testing Hypotheses Research-Based Strategies for Increasing Student Achievement Compiled from: Classroom Instruction That Works! By: Robert](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e305503460f94b207e9/html5/thumbnails/17.jpg)
Experimental Inquiry:
~ is the process of developing and testing hypotheses of things we observe.
![Page 18: Generating & Testing Hypotheses Research-Based Strategies for Increasing Student Achievement Compiled from: Classroom Instruction That Works! By: Robert](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e305503460f94b207e9/html5/thumbnails/18.jpg)
Historical Investigation:
~ is the process of identifying and resolving issues or contradictions from history about which there is confusion.

Systems Analysis
~ is the process of analyzing the parts of systems and the way they work together.

Group ActivityUsing the Decision Making strategy, work
with your partners to create your matrices.
1. Identify a decision that must be made in your school.
2. Identify the criteria on which the decision
will be made and the possible alternatives.
3. Assign weights to each criterion, assign a rating and complete the matrix.

Key Points Techniques for generating and testing
hypotheses may be inductive or deductive.
Techniques for generating ideas and testing hypotheses that are more deductive in nature seem to have a greater effect on achievement than inductive techniques.
There are a variety of structural tasks that can be used to help students through the process of generating and testing hypotheses.

Reflection on Learning
1. What have you learned about generating and testing hypotheses?
2. What questions do you have about generating and testing hypotheses?
3. What changes might you make in your practice related to generating and testing hypotheses?
4. What support might you need to make these changes?
