INFORMATION-REARRANGING PROCESS
Deductive Reasoning:
All men are mortal.Socrates was a man.
Therefore...

TRY A FEW MORE…(JUST TO MAKE YOU SMILE!)
All teachers are educated.Dr. Butler is a teacher.
Therefore…
Dr. Butler loves cats.Bigs is a cat. Therefore…

DEDUCTIVE THINKING
Process of thought that leads from one set of principles to another based on principles of logic.
Allows thinkers to extract implications from what is already known
Information rearranging processThe process most dependent on
formal learning

INDUCTIVE REASONING VS. DEDUCTIVE REASONING
Inductive reasoning is often used more than deductive reasoning
Inductive thinking is information extending, practical reasoning, seeing what in practice can be accomplished
Deductive thinking is information rearranging, theoretical reasoning, seeing what in principal must be true
Ex: What We Need VS What We Want
VS

INFORMATION REARRANGING & DEDUCTIVE THINKING SKILLS
Skills for deductive reasoning: Evaluation Skills: Assessing
information, determining criteria, prioritizing, recognizing fallacies & verifying
Analyzing information skills/problem-solving strategies: recognizing, classifying, identifying assumptions, identifying main ideas, & finding sequences
Problem Solving: compare and contrast, principles of logic, inferential thinking, & identification of causal relationships
Quick Test...

SPREADSHEETS FOR FUN???
Well planned spreadsheet activities emphasize reasoning, problem solving, making connections, and communicating mathematical ideas (Holmes, 1997)
Todd Funkhouser, teacher of Algebra 1 Rearrange information The Fun Factor Discussion – real world

THINKING ABOUT THINKING: METACOGNITION
Metacognition is the awareness of our own thinking process
Awareness – activities that foster awareness? Metacognition is the monitoring and guiding
of one’s own thought processes; mind observing and correcting itself
Example: Mr. Foster & The Lemmings

LEARNING FROM LEMMINGS
Reflection on problems Describing solutions Scaffolding Teaching/helping peers Chance to create problems Challenges Deductive Reasoning Evaluations Cross Curricular Variety of Programs

REVIEW OF HEURISTICS General Problem Solving Strategies Problem solving process can be taught Metacognition can be taught Example: War of the Worlds Alien Project
![Page 11: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/11.jpg)
PUTTING THE PROBLEM AT THE CENTER
Student learning views are shifting from transmitting skills and knowledge to helping develop confidence, skills, and knowledge necessary to solve problems and become independent learners and thinkers. (21st Century!)
Anchored Instruction – offers a framework for merging problem solving with content specific instruction
Creates environment of sustained exploration Help novices adopt skills of experts with tools
![Page 12: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/12.jpg)
MICRO-CONTEXTS VS MACRO-CONTEXTS
Micro-contexts focus attention on smaller subsets of a larger problem If learning about the environment, focus on
pollution’s effects on one animal Macro-contexts allow exploration of a
problem space for extended periods of time and from many perspectives Spend a vast amount of time researching and
examining several animals Emphasis on the importance of creating an
anchor or point of focus enables students to identify and define problems, and their perception of the problem
![Page 13: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/13.jpg)
MAJOR GOAL OF ANCHORED INSTRUCTION
Enable students to notice critical features of
problem situations and to experience the changes in their understanding of the
anchor as they view the situation from new points
of view.
![Page 14: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/14.jpg)
GREATEST ADVANTAGES OF ANCHORED INSTRUCTION
Use of complex, realistic contexts to provide meaning and reasons for why information is useful
Grasp abstract ideas Allows teachers to direct the student’s
attention to general problem solving Authentic activity: Factual Level, Degree of
Reflection, For whom are the tasks authentic Focus on the relevant features of the problem
they are solving
![Page 15: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/15.jpg)
PROBLEM-BASED LEARNING
Also known as Problem-Centered Learning Built around Real-World problem of interest Creates situation where students “do”
instead of mastery of facts Pick problems that are contemporary,
nontrivial, and real (not realistic) Examples?
![Page 16: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/16.jpg)
PROBLEM BASED LEARNING
Practice Life Skills: ability to make decisions raise awareness of complexity of
real world issuesacquiring body of knowledgedeveloping capacity for self-directed
learninggenerating the ability and desire to
think deeply and holistically
![Page 17: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/17.jpg)
AUTHENTICITY!!The more authentic the problem –
the more closely the problem resembles life – the more learners
respond!
![Page 18: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/18.jpg)
GREENBURG’S (1990)
GOOD PROBLEM SOLVING CHARACTERISTICS
1. Demands that students make a testable prediction
2. Makes use of relatively inexpensive equipment
3. Complex enough to elicit multiple problem-solving approaches from students
4. Benefits from group efforts5. Problem solvers must view
the problem as relevant (Added by Brooks & Brooks, 1999)
![Page 19: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/19.jpg)
ILL-DEFINED PROBLEMS
Effective problems at the center of the curriculum are ill-defined
These problems are ones that need more knowledge than is initially available
Problems where there is no absolutely right way or fixed formula for conducting an investigation
New information = change of ill-defined problems
Element of risk Real as if in the adult world
![Page 20: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/20.jpg)
TEACHERS AND PROBLEM BASED LEARNING
Still content experts but expertise is used to facilitate and guide
Craft problems Specify content Decide process goals Create criteria to
measure success Embed problem
situations at certain points
![Page 21: Teaching with Technology Chapter 5 Presentation](https://reader035.fdocuments.in/reader035/viewer/2022070320/55858da5d8b42ac76d8b45bb/html5/thumbnails/21.jpg)
COLLABORATIVE LEARNING IS BEST
Problem-based learning is best suited for group work
Gives students control over the process of learning new material and representing what they know
