You are listening to episode 17 of the ready, set, science podcast. Science classrooms have long been associated with step-by-step laboratory experiments, where students follow a prescribed set of instructions to achieve predetermined outcomes. While these traditional labs might appear to be straightforward and easy to implement, they hinder true scientific exploration and critical thinking. In this episode, we will explore the drawbacks of using step-by-step labs in science classrooms and highlight the benefits of embracing inquiry-based learning approaches. Are you ready, get set, let’s teach science!

• I know that we have all assigned recipe labs in our science classrooms. In fact, many of us probably remember doing them in school. But how are they connected to real world science? The truth, they aren’t. There is not one specific way to do science and there’s no one right answer to science problems. So why are we teaching our students that there is one way to do science?

• The Problem with Step-by-Step Labs

  • Limited Creativity and Problem-Solving Skills 

    • Step-by-step labs often restrict students to a fixed procedure, leaving little room for creativity and innovation. This rigid approach limits their ability to think critically and develop problem-solving skills, which are crucial for real-life scientific challenges. Scientific discoveries rarely follow predetermined pathways, and students need opportunities to explore different approaches and embrace experimentation.

  • Lack of Real-World Context 

    • Traditional labs often present students with isolated scenarios, detached from real-world applications. This lack of context can lead to disinterest and reduced engagement in the subject matter. When students are deprived of understanding how science applies to their lives and the broader world, their motivation to learn and explore further diminishes.

  • Undermining the Scientific Process 

    • Science is an iterative process that involves formulating hypotheses, testing them, and analyzing results to draw meaningful conclusions. Step-by-step labs may skip crucial stages of this process, giving students ready-made results without delving into the underlying principles. As a result, students miss the opportunity to develop a deep understanding of the scientific method and its applications.

  • Single Learning Experience 

    • Every student is unique, with varying levels of interest, aptitude, and prior knowledge. Step-by-step labs provide a one-size-fits-all approach that might not cater to the diverse needs of learners. Embracing a more open-ended approach allows teachers to adapt their instruction to the interests and abilities of individual students, promoting a more inclusive and dynamic learning environment.

• The Advantages of Inquiry-Based Learning

  • Fostering Curiosity and Inquisitiveness 

    • Inquiry-based learning encourages students to ask questions, explore, and investigate real-world problems. By nurturing their natural curiosity, students become more engaged in the learning process and develop a lifelong passion for scientific exploration.

  • Developing Critical Thinking Skills 

    • When students are given the freedom to design their experiments, they must think critically about the variables, controls, and expected outcomes. This cultivates their ability to analyze data, make evidence-based conclusions, and approach problems from multiple perspectives.

  • Connecting with Real-World Applications 

    • Inquiry-based learning emphasizes connecting scientific concepts to real-world applications, making learning more relevant and meaningful for students. This approach helps them appreciate how science influences various aspects of their lives, fostering a sense of relevance and excitement in the subject.

  • Encouraging Collaboration and Communication 

    • Inquiry-based learning often involves group projects and collaborative problem-solving. Such activities promote teamwork and effective communication skills, which are essential in both scientific research and everyday life.

• While step-by-step labs have been a staple in science classrooms for generations, it is becoming increasingly evident that they may not provide the most effective and enriching learning experience. 

• By embracing inquiry-based learning, educators can empower students to:

  • think critically

  • explore their curiosity

  • apply scientific principles to real-world situations

• Creating a classroom environment that fosters open-ended investigation and problem-solving will not only deepen students' understanding of science but also instill a lifelong love for learning and discovery.

How to change recipe labs to make them more inquiry-based

1. Always start with a phenomena

2. Do not hand out step by step instructions

3. Give students time to work together to come up with their own procedures (share them with the class for feedback)

4. Let the students explore

5. Discuss what they found out and how it connects to the phenomena
