Traditional vs. Next Generation Models of Instruction

It's important to understand the the difference between traditional models of instruction and the mode of inquiry NGSS is built on. This post looks at the transition from the widely-used traditional model of teacher as a sage who distributes knowledge and students as sponges who recall that knowledge, to a next generation model where teachers act as coaches, and students as scientists and engineers in their own right.

Prior to that, students have language limitations (whether or not they are English language learners) that make it necessary to deliver content in more of an experience model.

At this level, the idea that content is merely delivered through a teacher is a bit more foreign, and teachers – even generalists – take pains to make lessons more experiential, which are naturally more in line with the next generation model.

However, around Grades 4 and 5, a transition occurs and the traditional model of science instruction starts to take over. For one thing, the science curriculum and resources become a lot more traditional. Science textbooks become the norm, and the teacher begins to model facts, demonstrate phenomena and explain what’s happening to students in ways that didn’t happen before. The students’ job then becomes to recall the facts, repeat the demonstrations and summarize the phenomena that they saw.

This is a classic traditional model, and it’s a mirroring process: The teacher plays the sage and distributes information while students sit and listen or read, ultimately just recalling the facts that were given to them. It isn’t by nature interactive, and it is very limiting.

A next generation model is very different. With the Next Generation Science Standards, curriculum as well as instruction (because curriculum sets the minimum and maximum, in many ways, of what instruction will become in the classroom), the next generation model teachers, students, content and skills have very different roles.

The teacher's role in a next generation inquiry environment is to tune the inquiry environment. The student's role is to use their science and engineering practice skills to develop and use the disciplinary core ideas and the crosscutting concepts. The teacher adjusts support, helps students understand how to engage appropriately, and redirects and monitors student teams in the classroom.

Students are able to show that they meet expectations not only by engaging in that process of developing and using the content, but also by being able to answer unfamiliar questions and solve problems using the skills and content.

They should be able to explain content and its relationship to each of the dimensions, or explain each of the dimensions and their relationship to content. As you can see, this model is much more dynamic. We’re looking at a change in system-level curriculum articulation in order to move from the first model to the second.

Consider: If a student is being nurtured appropriately by the curriculum (and therefore instruction) from September through June and from one grade level to the next, that student will be much better equipped to set into the role of scientist and engineer enthusiastically, with real command of skills and an ability to employ that habit of making connections.

This is a change in the student’s mindset that must be cultivated by curriculum and instruction, one lesson at a time, one unit at a time, as responsibility is slowly released and students are allowed to engage with content on their own. This is very, very important.

A question we hear a lot is this:

"I think we've been doing this already. Is there a litmus test for what science or engineering is, so we can tell if we’ve done this?"

The answer is simple:

If you’re not sure whether or not your curriculum aligns, go back to the STEM cycle and the nature of science of engineering. Ask yourself if students are being – that is a very intentional word – scientists and engineers.

Remember, science and engineering are not something that you do. They’re not like peddling a bike. They’re not like reading off of a page. Those are rote processes. Doing is rote. Being is creative. It requires something of students; it necessitates their ability to create, evaluate and analyze.

The bottom line is this: If your science or engineering curriculum is not about students being scientists and engineers, so that students are actually engaging the practices, using and developing content, then it's not next generation.
