4 Ways the NGSS will Change Your Labs

October 4, 2020 No Comments

Labs look very different in an NGSS Aligned classroom. The NGSS will change your labs in more ways than you think. Here are 4 ways that the NGSS will change labs in your classroom.

How are labs different in an NGSS Aligned class?

1. Labs don’t take place after lecture.

Before NGSS, teachers provided students with course content before they did a lab activity. The lab provided confirmation of what was taught by the teacher. We refer to these style of labs as confirmation labs.

However, in an NGSS classroom, experiences come first. So, students obtain course content by engaging in these experiences such as laboratory activities. Then, the teachers provides additional information to clarify what they have learned through discovery.

Why don’t labs follow course content?

When a discovery-based approach is used, students have a better understanding of the material. Also, students retain the information better because of the experience that they have had. Finally, this approach helps students develop vital critical thinking skills.

2. Say goodbye to cookie cutter labs.

Pre-NGSS, teachers often gave students labs where students followed a recipe-style procedure. Students were responsible for reading and carrying out the procedure. They were not responsible for planning the investigation.

This style of labs emphasized the result of the investigation rather than planning and carrying out the investigation. As a result, students ability to plan investigations suffered.

In an NGSS aligned classroom, planning investigations takes a more significant role. In fact, Planning and Carrying Out Investigations is one of the eight Science and Engineering Practices.

Unfortunately, some student struggle with making this shift. Check out this post to find out how I scaffold student investigations.

Here is a picture of the outline that I use to help my students plan their investigations.  I review the outline before they are able to conduct their investigations.  To view this resource on my TPT page, click here.  

3. The emphasis is on the practices rather than the Scientific Method.

According the Framework for K-12 Science Education, the Scientific Method should no longer be used in the classroom. Instead, students should be using the Science and Engineering Practices. These practices can be used separately or together to help students build an understanding of the nature of science.

To learn more about why the Scientific Method is no longer used, check out this post.

There are 8 Science and Engineering Practices. And, each of the practice has many subcomponents. These components are grade-band specific and help to provide insights about what the practices will look like in each band. To view the Science and Engineering Practices and their subcomponents, check out the NSTA Matrix for the Science and Engineering Practices.

What about the Lab reports?

In my classroom, I no longer require students to write formal lab reports. However, lab reports may be appropriate for higher level courses and when students have mastered the science and engineering practices.

4. The Science and Engineering Practices aren’t just for lab days.

Pre-NGSS, I set aside specific days to spend time doing hands-on activities. However, since I made the shift to the NGSS, students are exploring in my classroom all of the time.

By looking at the NSTA Matrix for the Science & Engineering Practices, I have been able to incorporate the practices in so many ways. Often, I just look at one subcomponent and incorporate it into my lesson plan. Other times, we spend one or more class periods engaging in laboratory style activities.
