Understanding Van Hiele Levels for Geometry

Teaching Geometry with an Understanding of the Van Hiele Student Development Levels
 We know that our brains develop in stages. From Freud and Erikson with their stages of development to Piaget with his teachings of scaffolding, they all knew that in some way we all learned in levels. In order to get to successfully get to the next level, you had develop the knowledge in the first level. 

However, this isn’t always the way that we approach teaching geometry in school.

​As teachers, we have a limited amount of time to teach lessons. Not to mention the competition we have for students' attention while they are in our classrooms. Even our youngest students have favorite “YouTubers,” video games, and TV shows. And this is all just piled on to the usual social distractions that we all experience without the technology.

​Something that a lot of our lesson plans are missing is an understanding of the Van Hiele levels and how it plays into understanding geometry concepts. Often when our older students aren’t grasping what we are teaching, it is simply because they aren’t ready for it.
 
When they were younger, they didn’t truly understand the first levels of learning.  And this is where the Van Hiele Levels come into play.
 
What are the Van Hiele Levels? 
 
This theory originated in 1957 by husband and wife team Dina Van Hiele-Geldof and Pierre van Hiele from the Utrecht University in the Netherlands. It helps to describe how students learn geometry. The Van Hiele levels have helped shaped curricula throughout the world, including a large influence in the standards of geometry in the US (source).
 
How do they work? 
 
Geometric reasoning starts as soon as we can start processing information and in early schooling. However, depending on the individual, the ages in each stage can vary, especially as they progress through school. Basically the level is dependent on the experiences that each student has, no matter what their age.
 
In Learning Mathematics in Elementary & Middle Schools, Cathcart, et al ”In general, most elementary school students are at levels 0 or 1; some middle school students are at level 2.  State standards are written to begin the transition from levels 0 and 1 to level 2 as early as 5th grade “Students identify, describe, draw and classify properties of, and relationships between, plane and solid geometric figures.”  (5th grade, standard 2 under Geometry and Measurement)  This emphasis on relationships is magnified in the 6th and 7th grade standards.” (source)
Teaching Geometry Using Van Hiele Levels of Development

Level 0: Visualization
 
They can recognize shapes by their whole appearance, but not its exact properties. For example, students will think of a shape in terms of what it “looks like.” A rectangle is a door or a triangle is a clown’s hat. And the student may not be able to recognize the shape if it’s rotated to a different standing point.
 
Level 1: Analysis (Description)
 
Students start to learn and identify parts of figures as well as see figures in a class of shapes.  They can describe a shape’s properties and are able to understand that shapes in a group have the same properties as well. A student in this level will know that parallelograms have opposite sides that are parallel and will be able to group them accordingly.
 
Level 2: Informal Deduction / Abstraction
 
A student in this level will start to recognize the relationship between properties of shapes. They will also be able to participate and understand informal deductive discussions about the shapes and their different characteristics.
 
Level 3: Formal Deduction
 
At this level students are able of more complex geometric concepts. They can think about properties are related, as well as relationships between axioms, theorems, postulates and definitions. According to John Van Del Walle, students should be able to “work with abstract statements about geometric properties and make conclusions more on logic than intuition.”
 
Level 4: Rigor
 
Finally, students will reach the last level of learning geometric reasoning. Even in the absence of concrete examples, they should be able to compare geometric results in different axiomatic systems. Basically, they will see geometry in the abstract. Mostly, this is the level of college mathematic majors and how they think about geometry.
 
Some students may seamlessly pass through these stages, while others may be get a little left behind. And in the meantime, of course the curriculum keeps going, so without proper attention to the missing links or tutoring they won’t ever be able to full catch up with the lessons.
 
You can dial in your student’s Van Hiele level understanding by including some extra activities in your classroom. Make sure to check out these ideas from NRICH.ORG.

i want to know more about the Van Hiele teaching sequence to outline my teaching and learning activities on plan a lesson on geomentry for grade 1-3.

Hi Selmak,
That's great! I hope this helps. Definitely check out the links I included toward the end of the post here. That should help. Good luck, and thanks for commenting! Have a great day,

Pierre and Dina were my Opa and Oma. Sadly I never met my Oma because she died before I was born, but Opa used to visit us in New Zealand were he loved tramping (hiking) and sightseeing..

It postulates five levels of geometric thinking which are labeled visualization, analysis, abstraction, formal deduction and rigor.
