Classroom Wisdom That Still Shapes Science Teaching Today

As science teachers, we know that a strong start can set the tone for the entire school year. Few educators have influenced that mindset more than Harry Wong, whose classic book The First Days of School has guided countless teachers in creating structured, respectful, and effective classrooms.

Though originally published in the 1990s, Wong’s principles are timeless and still highly relevant for today’s high school science classrooms, where clarity, consistency, and student responsibility are key. Here are a few of the most impactful strategies from the book that continue to resonate:

1. Teach Procedures, Not Just Content

Wong emphasizes that effective teachers spend the first days teaching how the classroom runs, not just what students will learn. In a science setting, this could mean explicitly teaching lab safety routines, how to set up equipment, or the procedure for turning in assignments. The result? Fewer disruptions and more learning time.

2. Start Strong Every Day

One of Wong’s signature strategies is beginning every class with a consistent opening activity. In science, this might be a warm-up question, a short data analysis, or a "phenomenon of the day" video. It builds routine, signals that learning starts immediately, and gives students a moment to shift into science mode.

3. Positive Expectations

Wong reminds us that students rise or fall to the expectations we set. In a high school science class, this could mean holding students to high standards in lab behavior, collaborative discussions, or the precision of their scientific writing. Framing these expectations as a belief in their potential builds a culture of respect and effort.

4. Consistency is Key

From daily routines to grading practices, consistency builds trust. Wong’s work reinforces that predictability in how the classroom runs gives students the security to focus on learning, essential in a hands-on, inquiry-driven subject like science.

Harry Wong’s legacy reminds us that while technology, standards, and curricula evolve, the foundation of good teaching remains the same: clear structure, high expectations, and a belief in every student’s ability to succeed. His strategies continue to empower science teachers to create classrooms where learning isn’t left to chance, it’s built from day one.
