Section 1
What’s involved in meaningful
learning in science?
Setting the ‘context’ for understanding the power and
potential of concept mapping to support quality teaching
and meaningful student learning in science
What Constitutes Meaningful Learning in Science?
• Meaningful learning is a cognitive process in which
learners build conceptual understanding in science which,
in turn, can be accessed and applied as prior knowledge
under conditions of automaticity to new learning tasks
• When meaningful learning occurs, learners are able to:
– represent and explain the central ideas and organizing principles in
a domain
– construct rich explanations and predictions
– formulate significant questions
– apply knowledge in many situations and contexts
– organize new concepts within their existing conceptual framework
Requirements for Meaningful Learning in Science
– A curricular structure that organizes science content in
a conceptually coherent and meaningfully sequenced
fashion
– A curricular structure that provides opportunities for
students to be able to:
• organize their knowledge around core concepts (big ideas) and
concept relationships
• explicitly relate what is to be learned (new knowledge) to what
has already been learned (accessing prior curricular
knowledge)
• learn more about what is being learned (depth of knowledge)
• engage in cumulative review of what has been learned
• automatically apply their knowledge to similar or new contexts
Consensus Research Findings About Meaningful Learning..
Recent Research Related to Learning
with Understanding…(Bransford, et al, 2000)
3 Major Findings…
• Prior Knowledge is a major
determinant of future learning
•Understanding involves organizing/
re-organizing knowledge around core
concepts
• Learning involves knowing when to
use prior knowledge and skills for
future learning (metacognition)
Meaningful Learning –
Finding # 1: Prior Knowledge….
Recommendations for Teachers….
• Teachers must draw out students prior knowledge creating classroom
tasks and conditions under which student thinking is revealed (and
often archived for later reference)
• Teachers should use frequent formative assessment to determine
essential student learning and meaningful understanding as instruction
unfolds
• Teachers must build student prior knowledge, if necessary
Meaningful Learning
Finding # 2: Big Ideas/Core Concepts
Recommendations for Teachers…..
In order for students to develop understanding in an area of study, they
must:
– (1) have a deep foundation of factual knowledge
– (2) understand facts and ideas in the context of a conceptually
coherent framework, and
(3) organize knowledge in ways that facilitates retrieval and
application (e.g., such as can be done with propositional concept
maps)
Meaningful Learning
Finding #3: Thinking about what one knows…..
Recommendations for Teachers…
– must develop a metacognitive approach to instruction enabling
students to learn how to take control of their own learning by
always relating new knowledge to what they already know,
defining their own learning goals, and monitoring their own
progress in achieving them
IF Meaningful Learning Serves as the
Basis for Understanding, THEN……..
Consider the following chain of ideas:
Teaching meaningful science content…
a)
provides a coherent context for building conceptual
understanding
b)
serves as the conceptual basis for linking all instructional
activities to the knowledge (core concepts) to be learned,
THEN
c)
results in cumulative development of understanding which is
comprehension – a
powerful added bonus!!!!!
the basis for reading
Consensus Research: Conclusions Relating to the
Role of Knowledge in Reading Comprehension
Rand Research Findings
•Recommends more contentarea reading
•Defines comprehension as…
The simultaneous
process of extracting and
constructing meaning
from print materials or
other forms of
communication

Section 2
What are the characteristics of
propositional concept maps and how
do they differ from other forms of
graphic organizers?
Propositional Concept Maps..
• What are they….
– As a product, they are graphic organizers that present the
conceptual structure of the knowledge within a discipline (big
ideas, core concepts and relationships) in an hierarchical fashion
and utilize propositional statements to express the relationships
– As a strategy, propositional concept mapping is a dynamic,
interactive process in which students or teachers can organize and
represent their own conceptual understanding
– As a tool, propositional concept maps are engineered for ease of
use when building coherent curricular structures, developing
blueprints for instruction and assessment, and as a dynamic
interactive tool to support student learning and expository writing
As a Product - Emphasis on “Big Ideas”:
• The National Research Council (NRC) in the NSES
suggested that BIG Ideas:
– Represent the central ideas and organizing principles in a
domain
– Facilitate rich explanations and predictions
– Motivate the formulation of significant questions
– Are applicable in many situations and contexts
– Provide the basis for organizing concepts
Propositional Concept Maps: As A Tool
Perspectives from Cognitive Science
Illustrates how knowledge in any meaningful domain
(e.g., biology, economics) has an inherent
structure that….
• permits many other concepts to be related to it
• is a requirement for effectively using and applying
knowledge broadly
• is the central issue associated with transfer of
knowledge to other contexts and situations (Bruner,
1963)
Biological Classification

PCM: As A Tool ….Can Help Us Build Coherent Curriculum
PCM as a Tool have the characteristics that exemplified the
evidence that Bill Schmidt identified as part of the TIMSS
Study—that is the science curriculum in high performing
countries was….
• “Focused”
– Curriculum was organized around Big Ideas and core concepts that
support linking concepts for in-depth learning
• “Coherent”
– Content was conceptually organized and meaningfully sequenced
• “Articulated”
– Content was vertically and horizontally communicated across
grades and schools
• “Sufficient”
– Curricular content had no critical gaps or overlaps in the concepts
being presented
Propositional Concept Maps –
Major Curricular Myth Busters…..
Organized Curricular Sequences
(..in the form of PCM)
• Build understanding of core
concepts and concept
relationships
• Require the use of questions to
strategically link prior
knowledge with new
knowledge in order to deepen
understanding
• Advocates practice, extension
activities and cumulative
review
• Advocates the importance of
concept learning
“Covering” the Curriculum
• Emphasizes coverage of topics
rather than deep, meaningful
learning
• Uses reading and answering
questions as a pathway to
understanding; sample question
of the day
• Uses lots of skill and drill
• Form vs substance (i.e.,
thinking skills instead of
gaining knowledge)
PCM: A Tool for Constructing Conceptually-Organized
Science Curriculum as a Foundation for In-Depth Learning
• Implementing a coherent science curriculum is the main way in which
most students build what E. D. Hirsch calls “Intellectual Capital”
– Can be compared to “the rich get richer”
– Enables one to participate in conversation (and get the punch line in a
joke)
– Enables one to communicate effectively
– Enables one to comprehend complex texts
– Determines what new knowledge students pay attention to
– Determines how new knowledge is perceived
– Suggests what learners judge to be important
– Determines what they actually learn and remember
Propositional Concept Maps are not….
• Fishbone Diagrams (cause/effect)
• KWL Charts (compare/contrast)
• Flowcharts (time order/cycles)
• Frames (Boxes) (problem/solution)
• Concept Circle Maps (listing)
• Semantic Webs (chunking)
And here’s why: Because PCM represent knowledge
hierarchically, use linking verbs to connect concepts, and
provide a tool for learners to represent their understanding
at a much deeper level
Section 3
How are propositional concept maps
constructed?
PCM - Construction Features
• Concepts are represented as nouns in boxes
• Concepts are linked using verbs and verb phrases which are
located on lines connecting boxes
• Concepts (nouns) and linking words (verb phrases) always
represent propositional relationships in the form of complete
sentences
• Lines end with arrows to denote direction of the concept
relationship being represented
• Concepts that apply broadly to the entire map are connected to the
top concept (super-ordinate concepts)
• Concepts that are equally important are organized along the same
plane

PCM –General Construction Guidelines…
General Suggestions ……
• Construction guidelines exist for both teachers and students
• PCM’s are best constructed by individuals working in small groups
• PCM’s can be constructed using postit notes and large sheets of paper
or on the computer using software such as Inspiration (or Cmap Tools)
• PCM can be linked together as a family of maps rather than crowding
too much information on one map
• PCM’s can and should be modified as knowledge becomes more
refined
• PCM’s should reflect a reasonable representation of how one thinks
the knowledge being learned should be organized
Step-by-Step: Teacher Guidelines for Constructing PCM’s
• Select a topic area, unit or mini-unit for study (or big idea and
benchmarks)
• Identify major concepts and sub concepts and place on individual
postit notes
– Different sources can be used (e.g., benchmarks, textbooks, teacher
knowledge)
– Line concepts up so that you can easily see all of them (parking
lot)
• Concepts are represented in the form of nouns and noun phrases (e.g.,
states of matter) and placed in boxes or on individual postit notes
• Keep the number of concept words on each postit note to a minimum
(e.g., one or two)
Teacher Guidelines for Construction of
Propositional Concept Maps
• Caution!
– Don’t try to organize concepts while simultaneously
brainstorming all the ideas you consider important
– Don’t worry if you have too many concepts as you can
always delete some later
• Ask: What is the general organizing concept or most
subsuming concept that can serve to organize the topic?
Place it on top of map
• Next: Select the next layer of major concepts that organize
(or categorize) the topic into broad subtopics,
Step-by-Step Guidelines for Construction PCM’s
• Begin to arrange/organize concepts on paper or technology tool
(anywhere you decide to construct the map)
• Rehearse – that is, think about what linking verbs represent the
relationship you are trying to represent and can assist you in creating a
complete proposition or thought (complete sentence)
• Important Note: Initially all links (e.g. verbs) should be written in
pencil to allow for any changes in position or wording
• Maintain focus on relatedness among concepts as the key for
organizing the concepts
• A single map cannot represent everything you know about a topic (use
sub-maps for elaborations)
Step-by-Step Guidelines for Construction of PCM’s
• Don’t hesitate to add or delete concepts, as needed
• Arrows positioned at end of links are helpful in showing
flow of concept relationships
• Specific examples and small details are usually placed at
the bottom of maps
• Continue: Use the same process for each concept on a
map, arranging and linking as appropriate.
• Read map aloud to yourself. Ask: Does it make sense? Edit
and rearrange as necessary...

Section 4
When and how are students introduced to
propositional concept mapping?
PCM Introduction to Students…
• Several approaches can be useful: (Whole Class)
– Unit/Lesson Starter: Map exists, can be displayed in
classroom and students receive orientation to map structure as well
as reference it throughout instruction (big idea overview approach)
– Unit/Lesson Summary: Teacher has copy of map; teacher
guides the identification of all key concepts (vocabulary) being
learned; teacher models out-loud how he/she would organize the
concepts and explains the basis for the organizational structure
– Textbook Page Summaries (and for Comprehension):
Teacher guides student use of the knowledge-based reading
comprehension intervention (KBI) with course textbook or reading
packets, identifies key vocabulary terms, and guides whole class
construction of the propositional concept map using key concepts
and relationships discussed

PCM: Strategic Uses for Students
Concept Mapping by students emphasizes the role of
conceptual knowledge in:
• Content-area reading comprehension (e.g., solar system
example)
• Blueprint for written composition / communication
• Tool for independent study or for preparation for tests
• Visual representation and review of concept
relationships
PCM: As An Instructional Tool
• Student construction of PCM requires…
– Numerous episodes of modeling PCM construction by
teacher
– Numerous opportunities for guided practice - small
groups of students begin to construct PCM
– Opportunities for whole class sharing and revising of
PCM
– Further modeling, guided practice and independent
practice
PCM: As An Instructional Tool
• Benefits to students
– Encourages students to discuss concepts and concept relationships
(develops vocabulary)
– Provides a means for them to represent how they think and what
they understand about concepts being learned
– Builds and reinforces strategic learning strategies and skills (e.g.,
cause/effect relationships; similarities/differences; core ideas and
scientific principles; logical development of ideas)
– Develops collaborative learning environment for students
– Supports reading comprehension

PCM for Teachers …As A Curriculum Tool
• Curriculum Concept Maps help to– Organize the school and/or grade level curriculum (vertical and
horizontal coherence and articulation)
– Highlight ‘big’ ideas (Fl Next Generation Benchmarks) in the
curriculum as organizing concepts for learners
– Prioritize concepts to be taught (less is more)
– Identify ‘gaps’ in the curriculum
– Identify concepts which can be used to connect other disciplines
– Establish consistency among the curriculum units being taught at a
grade level or for a course
– Evaluate text-based and other instructional resources

PCM: An Instructional Tool for Guiding the Student
Content-Area Reading Comprehension
• Teachers model and guide student construction of
PCM as they read for understanding and meaning.
For example,
– Demonstrate to students how to construct maps as a
representation of how they comprehend the text-based
materials being read; then let them work in small
groups
– Help students represent their understanding of key
vocabulary by graphically representing relationships
among concepts using print materials
PCM: An Instructional Tool for Guiding the Student
Writing Process
• Curriculum Concept Maps…
– Serve as a blueprint to guide and support
student expository writing
– Develop student construction of passages rich
in detail/support and elaboration of key ideas
– Organize student thoughts for multiple literary
genres (narrative, expository and persuasive)
Propositional Concept Maps:
An Assessment Tool
• Curriculum Concept Maps help to– Provide a clear view of the important concepts to be taught and
tested
– Provides a list of key vocabulary
• Using Curriculum Concept Maps as the Assessment
– Delete connecting verbs and have students fill in
– Delete concepts (nouns) and have student fill in
– Have students create their own maps working first in small study
groups
– Have student create individual maps
– Have students create a map to serve as a measure of their reading
comprehension and understanding
Conclusion
• Concept maps have the potential to improve
the quality of instruction in any content
domain for which conceptual coherence is a
requirement for in-depth, meaningful
understanding
• Clearly, concepts maps have great potential
for enhancing both instructional practices
and student learning
