How the STEM SOS Model Transforms Classroom Engagement and Learning

Introduction

This excerpt is taken from the book Based on Practice STEM Teaching Model – STEM Student Showcase . The Harmony Public School (HPS) in the United States created the “STEM SOS” curriculum to deliver rigorous teaching in an engaging, fun, and efficient way. The passage presents parts of Chapter 4, which studies the implementation and student feedback of the STEM SOS model.

Teaching Phase

At the start of a STEM SOS class, teachers introduce core concepts, outline the course structure, and check understanding through questions. Students describe the teacher as interactive, using one‑on‑one and group dialogues, real‑life examples, experiments, and videos rather than pure lecturing. The teacher continuously monitors comprehension, encourages students to connect formulas with everyday phenomena, and avoids rote memorisation.

Teachers also integrate varied activities—experiments, video viewing, and student‑led teaching—so that students actively participate rather than passively listen.

Practice Phase

Hands‑on projects are central to the STEM SOS model. Students report that practical activities keep them focused, linking textbook theory with real‑world applications. They showcase their work at STEM fairs and competitions such as ISWEEEP, reinforcing learning through repeated presentations.

Student Teaching

In the final stage, teachers assign short personal or group tasks that require students to teach a concept to the class, often using experiments or video demonstrations. Students assume the role of “mini‑teachers,” designing experiments, creating instructional videos, and even building websites to document progress. Long‑term projects may span an entire academic year, with students selecting topics from a posted list, producing videos, manuals, and presentations for school exhibitions and visiting officials. This process builds confidence, deepens scientific attitudes, and fosters a sense of belonging.
