Teaching High School Biology? Avoid these common mistakes.

Teaching high school biology is full of challenges and some of them are fun and some of them are not so much fun. Learning how to teach biology is a challenge because you’re trying to strike a balance of engagement, covering the standards, keeping the chaos corralled, and not teetering on the brink of exhaustion yourself. I wanted to share 5 common mistakes I have made and see other teachers make over and over again when teaching high school biology.

Overlooking the Power of Pre and Post Assessments

You know those moments when you dive straight into a lesson without pausing to check where your students stand? Guilty as charged. This is first because it has made the biggest impact on how I teach biology. Neglecting pre-assessments is like setting sail without a compass – you risk losing your way. Similarly, forgetting post-assessments means missing out on the chance to chart your progress.

These assessments are essential for gauging students’ prior knowledge, tracking their progress, and evaluating the effectiveness of instructional methods. It helps you collect the data you need to drive your decision making. This data may prove useful if a question ever arises.

By neglecting pre-assessments, teachers miss valuable insights into students’ baseline understanding of the subject matter. Similarly, failing to administer post-assessments means overlooking opportunities to measure learning outcomes and identify areas that require further reinforcement.

I like to use pre and post assessments at the beginning and end of each unit to help me see if. what I am doing is contributing to students’ understanding and application of the material taught in class. This helps me know how to adjust teaching strategies and where I may need to reteach before moving forward.

Turning a Blind Eye to “Kid Stuff” Activities

Ever dismissed those “babyish” activities like color by number or word scrambles, thinking they’re too elementary for your high schoolers? Been there, done that. But here’s the thing – those seemingly juvenile activities can work wonders in reinforcing concepts and engaging diverse learners. These activities are often viewed as low stakes and can engage some of your more resistant learners. The additional learning methods that many of these types of activities employ are a great way to reach more students.

Solution: Balance traditional “grown up” teaching methods with interactive and hands-on activities. Incorporate games, puzzles, and coloring activities strategically to engage students and reinforce key concepts in a memorable way.

Forgetting to Give Students a Say: Lack of Student Choice

Would you rather go to a banquet where everyone has the same meal or a high end restaurant with lots of options? Students like having a choice too. There is a lot of ways students have little to no control in their high school education. Giving them some autonomy may decrease their resistance to getting things done.

Solution: Implement choice boards or project menus that offer students a variety of options for demonstrating their understanding. Providing choices empowers students to take ownership of their learning and encourages creativity and critical thinking. I usually use choice boards for end of unit assignments and projects.

Ah, the classic disconnect between lab experiments and classroom content. Guilty as charged, once again. Failing to bridge the gap between hands-on activities and theoretical concepts can leave students feeling adrift in a sea of scientific jargon. A confused student can quickly escalate into classroom management issues.

Solution: Before conducting a lab, explicitly connect it to the relevant course content and learning objectives. Spend more time preparing them for the lab and debriefing them at the end. This is the time for you to clearly help them connect the hands-on and the concepts from the standards.

Remember those times when you introduced a concept like biomolecules and then never circled back to it? This habit has taken a lot of failed attempts for me to finally break. I think it is because I was always presented the material in a disconnected way and let’s be honest it takes time to make those connections. The thing is biology isn’t a series of standalone topics – it’s a group of interconnected ideas. Failing to weave these threads together can leave students with a fragmented understanding of the subject.

Biology is a multidisciplinary field with interconnected concepts spanning various levels of organization. Think about all the disciplines within biology.

Solution: Emphasize the interconnectedness of biological concepts by explicitly making connections between different topics throughout the course. Encourage students to explore how concepts like biomolecules relate to larger biological processes and phenomena. By integrating concepts, students develop a more holistic understanding of biology. I like to come back to chemistry/biomolecules, organization of life, and characteristics of life when I introduce a new topic.

Teaching high school biology takes practice

In conclusion, teaching high school biology effectively requires careful planning, thoughtful assessment strategies, and a commitment to engaging students in meaningful learning experiences. Over time you will find your practice improves. By avoiding these common mistakes and implementing proactive strategies, educators can create a supportive learning environment where students thrive and develop a deep appreciation for the biological sciences.
