STEERING THE BEAUTY OF TRIGONOMETRY IN THE REAL WORLD

By Mr. Jerom Loremia Melecio (Mr. Jay)

Trigonometry is one of the most valuable branches of mathematics that is widely used in architecture, engineering, and many other sciences. It is one of the mathematical divisions that accentuate the mathematical and geometrical reasoning about triangles, particularly right triangles. Triangles are one of the simplest geometrical figures with speckled applications in the real world, so much so that Trigonometry is specifically dedicated for the scientific study of the precise measurements of triangles. The study of the principles and application of Trigonometry not only help develop the students’ problem solving skills but also the appreciation of beauty and deeper understanding of the world around them.

For this week, the Secondary 3 students explored, navigated and learned about trigonometric concepts to solve problems and to appreciate and understand its applications in the real world. More specifically, the objective was for the students to gain knowledge, understanding and skills on the relationship of the six trigonometric ratios to right triangles and to apply them in solving real-life problems.

Using a variety of teaching strategies including, but not limited to, open-ended questions, Q & A, mnemonic, board work and collaborative discussions, the teacher started the lesson with a problem presentation with the intent of initiating a dynamic class discussion. More problems were introduced in the class to encourage the students to think more critically as they tried to apply the new trigonometric concepts learned for the day. After the discussion, practice exercises and board work activities were given as formative assessments. The students were required to work cooperatively and to think critically by demonstrating their ability in manipulating the algebraic and trigonometric expressions in solving the assigned real-world problems. After the allowable time, the students were asked to present their work-output in the class, which also provided them an opportunity to build self-confidence and practice communication skills.
