Evaluation of the Bar Model method: strengths and limitations
Strengths:
-
An easy-to-learn visual representation of the quantities and the relationships between the quantities in solving maths problems.
-
Good for all students but especially for underachieving or intermediate-level students.
-
Good for solving basic maths problems in primary maths.
-
Good for solving arithmetic problems involving four operations of whole number, decimals, fractions, rate and ratio, and percentage problems.
-
When used effectively, the model method can be a very powerful tool in solving even complex maths problems.
-
Could provide a bridge from arithmetic to algebra in students‘ learning in mathematics.
Limitations:
-
Not very applicable for solving maths problems in geometry and statistics.
-
For high-performing students, it might be not so helpful, and sometimes it could be a burden.
-
Drawing the length of different parts of the rectangle bars could be difficult, and sometimes the length cannot be known until the problems are solved.
-
Over-relying on model methods might make it harder for students to develop innovative and creative thinking.
-
Over-relying on model methods might make it harder for students to learn algebra.
Suggestion: Teachers should learn what the Bar Model method is, and how it can be used effectively in classrooms.
