Use an existing database

Using a Database

Searching– Looking for particular pieces of

information

Sorting– Purposefully reorganizing information

Question-driven

Why Ask Students Questions?To find something out.To determine what students know and don't

know.To check for comprehension or level of

understanding.To provide a review of material and content.To prepare students for what is to be learned.To teach students to ask questions

(modeling).To Develop thinking skills

Thought Provoking Questions

Critical Thinking and Inquiry– Collect, organize, describe, identify

relationships, interpret, evaluate, …

Databases can be “thinking” tools– Think about and experiment with data

and ideas

Develop inquiry/analytical skills

Low-level questions

– requires recall of information

Higher-level questions

– require processing information

Bloom’s taxonomy (M. p.24)

Knowledge – Remembering (recalling) appropriate,

previously learned factual information.

Comprehension– Grasping (understanding) the meaning of

informational materials

Application– Using previously learned information in

new situations to solve problems

Bloom’s

Analysis– Breaking down information into

component parts

Synthesis– Creatively applying previously learned

information and skills to produce new or original knowledge.

Evaluation– Making value judgments based on

informed opinions.

Lower level vs. Higher level Q’s

States Data Base–Which state has the highest

population?– List the top 5 states in terms of highest

per capita income?–Which 3 states have the heaviest

reliance on agriculture?–Which state is the best place to live?
