The Adusu AlgebraTM technique
The teaching of algebraic expressions, algebraic equations and algebraic inequalities is an area that has caused frustration for teachers and students alike for generations. One of the main issues is the abstract nature of equations/inequalities and the basics of algebraic expressions.
While some very basic concepts can be demonstrated with concrete materials such as cups and matchsticks, counters or other objects, the majority of algebraic manipulation is taught using algorithms and processes which are memorised.
No matter the school, age or ability of the student, the same issues occur time and again. Even high level mathematics students frequently demonstrate misunderstandings that were developed in younger years.
As teachers, we not only want students to get to the correct answer but to understand the process and the concepts so they can adapt their knowledge and skills to new situations, and be prepared for any future mathematical requirements in an ever changing world and job market.
While algebra itself has not changed for hundreds of years, the teaching of algebra is flexible and all teachers have their own repertoire of stories, pictures, tricks, diagrams, games, activities and even songs to help kids learn and remember each different aspect of algebra.
Students need to identify the question type, recall the correct process and apply said process without making an error to get to the correct answer. Students will commonly apply a remembered technique to the wrong type of question or apply operations in an incorrect order, or miss a detail (often a negative) along the way.
Adusu AlgebraTM utilises concrete materials so that students of any age, year level and mathematical skill can physically build and manipulate the expressions, equations and inequalities they encounter in secondary school.
The number of rules involved in this technique are minimal and logical, and provide a consistent approach, eliminating the need for the plethora of ideas and techniques generally employed. It alleviates the pressure on the student, reduces their cognitive load and provides a much higher rate of success.
Adusu AlgebraTM enables students to enjoy success with their learning and gives them confidence to attempt more difficult questions. It allows for differentiation by supporting students with basic questions as well as facilitating more advanced students to explore and attempt more difficult questions.
"I hope you enjoy using this technique as much as I have enjoyed developing it. I am still amazed at how comprehensive the technique is. It has changed how I teach algebra and it has completely changed how my students think and feel about algebra. If we can get kids engaged in the learning, and enjoying the process, then we are three-quarters of the way to achieving our goal. All the best, and have fun!"
