Concept Mapping Through the Conceptual Levels of Understanding Presented by Michael Sanchez Weslaco Independent School District The University of Texas – Pan American
About Me • Mathematics Teacher • Algebra I / Math Modeling • Algebra II • Pre – Calculus • Weslaco, Texas
Why Action Research? • Graduate Student • University of Texas – Pan American • Mathematics and Science Teacher Preparation Academy • Encourages Action Research in the Classrooms
Research Problem • Algebra II Students enter the course with incomplete understanding of the algebraic topics that were previously taught in previous grades. • Students lack connection between multiple representations. • Students struggle with the vocabulary behind the mathematics. • Students have difficulty understanding the concept of function and function transformations.
Reasons for Problem • Students are not taught algebra concepts as a whole. • Not enough emphasis on the use of vocabulary in instruction. • Instruction does not utilize the use of the conceptual levels of mathematics understanding.
Hypothesis • Using concept maps to support lessons based on the APOS theory and the Psychological Models of Mathematics Understanding will help students learn mathematical concepts at a higher level.
Theoretical Framework • APOS Theory • Dubinsky & McDonald • Constructivist Approach in constructing mathematical understanding • The Psychological Models of Mathematical Understanding • Kalchman, Moss, & Case (2001) • Describes levels of understanding through the use of digital and analogic schemata
Overview of APOS Theory • Four Levels of Understanding • Action • Process • Object • Schema
Action • Concrete processes • Counting • Grouping
Process • Collection of Actions • Formation of Patterns
Object • Using the Actions and Process to create a mathematical model to represent them.
Schema • Combining the Action, Process, and Object levels to create a complete understanding. • A mental framework used to solve similar situations.
Overview of the Psychological Models • Four Levels of Understanding built upon to primary schemata: digital (sequential) and analogic (spatial). • Level 1 • Level 2 • Level 3 • Level 4
Level 1 • Basic Computations. • Digital and Analogic Schemata done in isolation.
Level 2 • Digital and Analogic are used together and mapped to each other.
Level 3 • Students gradually categorize different contexts of application and are able to create to some extent different representations.
Level 4 • Students can explain the process and make differentiations of several “what if” situations. They see the concept as a whole rather than in isolation.
How can we expect our students to achieve this? • Concept Mapping as a tool to support the construction of conceptual understanding.
Why Concept Mapping? • Helps organize vocabulary and concepts by making connections between them. • Can create a hierarchy of concepts and make connections between them.
Implementation • Initial Topic • Functions • Function Transformations • Beginning Phases • Designing Skeletons to Foster Class Discussion • Mapping Representations • Matching Process Tables, Graphs, Symbolic Representations, and Verbal Descriptions.
The Shift • There was a need to adapt implementation. • District Timelines • Student Difficulties • Adapted use of Skeletons
Implementation • Quadratics • Lessons using the theoretical framework • Concept Mapping used to support understanding of process tables to symbolic representations. • Placed Emphasis on linking actions and process to object levels.
Results • Students enjoyed activities. • Liked the idea of starting at a concrete level and building upwards. • In initial phase students had difficulty creating their own maps. • Fostered whole group discussion through the use of the skeleton concept maps.
Reflections • Adapting to Change • Planning according to District Timelines and Benchmarks. • Learning Experience • Data Collection • Potential • Changed the way I create my lessons. • Anticipating Questions. • The Future! • Continuing Action Research past Graduate work.
