Enhancing Senior High School Students’ Ability to Solve Linear Equation Word Problems Through Interactive and Cooperative Problem-Solving Strategies
This action-research study demonstrates that implementing interactive and cooperative problem-solving strategies significantly improves senior high school students' ability to translate natural language word problems into linear equations by bridging the gap between linguistic understanding and algebraic modeling.

For many students, mathematics feels less like a tool for understanding the world and more like a foreign language they were never taught to speak. The challenge is not always a lack of intelligence or a failure to memorize rules, but a specific breakdown in translation. When a teacher presents a problem wrapped in a story about trains, money, or time, the student must first decode the natural language of the narrative, strip away the irrelevant details, and then reconstruct the core relationships into a formal mathematical structure. This translation process is where many learners stumble. They can often perform the necessary calculations if the numbers are handed to them directly, but they freeze when asked to build the equation themselves from a paragraph of text. This gap between reading a sentence and writing a mathematical model is a persistent barrier in secondary education, particularly in regions where high-stakes exams determine a student's future career and academic path.
In a classroom at Lashibi Community Senior High School in Ghana, a researcher named Abel Bronya set out to bridge this gap. The study focused on a specific group of forty-five first-year students, mostly young women studying home economics, who were struggling profoundly with word problems involving linear equations. Before any new teaching methods were introduced, the situation was dire. In a standard test administered under traditional lecture conditions, where the teacher explained the rules and the students worked alone, eighty percent of the class scored below average. Most of these students were not failing because they could not do the math; they were failing because they could not figure out what the math problem was asking. They would look at the numbers in the story and blindly perform operations without understanding the context, or they would simply stare at the page, unable to convert the words into a solvable format. The root causes, as revealed by later interviews, were a mix of fear, rigid teaching styles, and the sheer difficulty of navigating complex vocabulary without support.
To address this, the researcher replaced the usual lecture format with a two-week experiment in interactive, cooperative problem-solving. Instead of sitting silently and listening, the students were organized into small, mixed-ability groups. The new approach asked them to work together to dissect the story problems before they ever touched a pencil to write an equation. They were guided to identify what information was given and what was needed, to draw pictures of the scenarios, and even to act out the situations to make the abstract concrete. Crucially, they had to talk through their thinking, explaining their reasoning to one another and decoding the tricky language of the problem as a team. This method shifted the classroom dynamic from a passive reception of rules to an active, collaborative construction of meaning.
The results of this shift were immediate and dramatic. When the same students took a similar test after the two-week intervention, the distribution of scores flipped entirely. The number of students scoring below average plummeted from eighty percent down to just under seven percent. Conversely, the number of students achieving above-average scores soared from a mere three students to thirty-nine, representing nearly eighty-seven percent of the class. The qualitative feedback from the students supported these numbers; they reported feeling less anxious and more engaged. The group setting had removed the fear of making mistakes in front of the teacher, allowing them to ask questions and clarify confusing terms without shame. By articulating their thoughts aloud, they were able to correct each other's misunderstandings and build a shared mental model of the problem.
This study suggests that the barrier to solving algebra word problems is often not a lack of mathematical ability, but a lack of a supportive environment to practice translation. The traditional method of lecturing and individual seatwork, which dominated the students' prior experience, had failed to equip them with the tools to decode the narrative. The cooperative approach, by contrast, provided a scaffold where students could learn from one another, turning a solitary struggle into a shared discovery. The findings indicate that when educators move away from rigid, teacher-centered instruction and embrace collaborative, dialogue-driven learning, students can rapidly overcome deep-seated difficulties in applying mathematics to real-world scenarios. For the students at Lashibi, the solution was not harder work, but a different way of working together.
