Understanding, not Belief, in the NGSS Evolution Standards for High School
| Image from here |
Bottom line: The NGSS do not require belief in evolution. And that's really good news for teaching evolution in the South and other areas of the country where students resist learning about evolution. It's also really good news for public school parents, science teachers, and anyone developing curriculum documents. The NGSS keep public school classrooms safe for students who see a conflict between evolution and their faith.
Let's look first at the high school evolution standards from the NGSS. I'll analyze them standard-by-standard below, but I suggest that you first take a couple of minutes to review the standards as they are presented together. As you probably know, the NGSS are purposely written to fit many, many features together in each standard set. At the bare minimum, they intertwine content and process so that science teaching in America can no longer divorce the two. If you haven't seen it already, also make sure to see how the clarification statements and assessment boundaries help science teachers see the level of rigor NGSS is targeting for teaching evolution.
Now, looking standard-by-standard for belief versus understanding:
HS-LS4-1 Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence. [Clarification Statement: Emphasis is on a conceptual understanding of the role each line of evidence has relating to common ancestry and biological evolution. Examples of evidence could include similarities in DNA sequences, anatomical structures, and order of appearance of structures in embryological development.]
Clearly, this standard makes no requirement students believe in evolution. As I have advocated for years, this standard grounds students' work strongly in evidence by having them look at multiple lines. Then, they are to be able from that to "communicate scientific information" about evolution, and I hear in that portion of the standard a clear focus on students' understanding and communicating key science ideas without requiring any kind of belief from them.
HS-LS4-2 Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment. [Clarification Statement: Emphasis is on using evidence to explain the influence each of the four factors has on number of organisms, behaviors, morphology, or physiology in terms of ability to compete for limited resources and subsequent survival of individuals and adaptation of species. Examples of evidence could include mathematical models such as simple distribution graphs and proportional reasoning.] [Assessment Boundary: Assessment does not include other mechanisms of evolution, such as genetic drift, gene flow through migration, and co-evolution.] |
HS-LS4-3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait. [Clarification Statement: Emphasis is on analyzing shifts in numerical distribution of traits and using these shifts as evidence to support explanations.] [Assessment Boundary: Assessment is limited to basic statistical and graphical analysis. Assessment does not include allele frequency calculations.]
HS-LS4-4 Construct an explanation based on evidence for how natural selection leads to adaptation of populations. [Clarification Statement: Emphasis is on using data to provide evidence for how specific biotic and abiotic differences in ecosystems (such as ranges of seasonal temperature, long-term climate change, acidity, light, geographic barriers, or evolution of other organisms) contribute to a change in gene frequency over time, leading to adaptation of populations.]Same as the Standard 3 above--natural selection typically doesn't raise belief issues.
HS-LS4-5 Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species. [Clarification Statement: Emphasis is on determining cause and effect relationships for how changes to the environment such as deforestation, fishing, application of fertilizers, drought, flood, and the rate of change of the environment affect distribution or disappearance of traits in species.]With a focus on "emergence of new species," this standard will probably be the most difficult of the six for resistant students. Typically, they resist evolution because they simply do not believe new species can emerge on their own without supernatural influence. (I actually agree with them, and many practicing scientists agree as well.) But, clearly, this standard does not focus on changing students' beliefs. They are not to "accept the evidence supporting claims..." Instead, they are to "evaluate the evidence." Interestingly, I actually think this standard left a door wide open for a Teach the Controversy approach, which I am quite sure the NGSS authors did not attend.
Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.* [Clarification Statement: Emphasis is on designing solutions for a proposed problem related to threatened or endangered species, or to genetic variation of organisms for multiple species.]Again, clearly a focus on natural selection, since it's limited within the short time frame of human activity, and not one raising the specter of belief change.

Tweaking Inquiry
- How engaged are your students in scientific questions?
- How do your students give a priority to evidence when they are learning science?
- How adept are your students at developing explanations based on the evidence they're seeing?
- How adept are you at guiding your students to consider alternative explanations for the evidence they're seeing?
- How are your students constantly communicating and justifying their explanations?

Teaching Evolution Resources

See You in New Orleans?
- My Thursday session is workshop-styled, and we'll be focusing on specifics in the classroom. You'll walk away with a lesson plan for teaching whale evolution and an overview of the evolution unit I created in The Missing Link. If you've been to one of my sessions before on teaching evolution to resistant students, this is a good follow up.
- My Friday session is a big picture look at the issues involved in teaching. Do you have students afraid of evolution, maybe even hostile to it? I'll give you some good traction on the issue and show how you can be faithful to the science without attacking any faith-full students in your class.

Mirror Inquiry Ideas
I got inspired this week to move an inquiry I've been doing for years onto Prezi. Here's my vlog entry on what I learned in the process, including the following thoughts.
- Here's a link to the Mirror Inquiry on Prezi.
- The original concept for the inquiry came from Video #1 of the Minds of Our Own series.
- Transitioning from a hard copy to Prezi. An image of the old Word file is below.
- Starting to implement web-based video for bursts of instruction. Find all of the videos I researched at my mirror inquiry Delicious tag collection.
- Aha! I could use these videos from my iPad when working with small groups.
- Kids can go back to this Prezi whenever they want.
- Teacher's corners & Facilitator's corners.

Authentic Work for Authentic Audiences
I gave my students this as their final course question, "How will I solve the authentic problem I face of having no opportunity now for practicing the skills necessary for effectively managing student misbehavior?" As any experienced teacher knows, it's impossible to learn how to manage secondary students' misbehavior while sitting in a university classroom. So, I basically told my classroom management students, "Go find a misbehaving group of secondary students and figure how what to do with them?"
I'm so impressed with what they came up with, and what really struck me was the range of their products. Here's a list of the kind of products they used to show what they've learned:
- A brochure for future art teachers
- An image gallery of students taught and lesson learned presented in PowerPoint
- Blogs of lesson learned
- A hand-written journal of reflections
- A technical paper for future English teachers
- Memos from school officials stating their abilities
- A compelling narrative of growth based on the stories of prior experience
- A revision of prior work submitted, revised based on new lessons learned

Objections to Inquiry

Modeling vs. Simulation
The picture shows my son David participating in an activity at the Dauphin Island Sea Lab. The students' challenge was to design with Silly Putty a shape that fell very slowly in water. They were simulating zooplankton and how it's adapted to fall slowly through the water. I realized just a change in view could take this non-inquiry activity to an inquiry investigation. If the students are modeling, and the model is a good one, then they can actually collect data from their model's behavior.

Learning about Whale Evolution from National Geographic

In The Missing Link, I laid out an inquiry on whale evolution that uses data from a written article. This is a different style of inquiry than many people think of, since the students don't collect the data themselves. That would be kind of hard for them to do, right, since they're not paleontologists! So, this style of inquiry has them looking at, thinking through, and explaining data that other scientists have collected and published.

Resources for a Lesson on the Evolution of HIV
- Lesson Purpose: Students examine evidence of the evolution of HIV in response to antiviral drugs as an example of evolution occurring in their lives right now
- Focus Question: What does the theory of evolution say?
- The Geography Search Interface from HIV Databases Site gives a pretty amazing tool by which students can examine the evidence for geographical distribution of different strains of HIV worldwide. Great for visual and kinetic learners!
- If you or your students need to brush up on understanding HIV's basic structure or life cycle, a simple Google Images search gives a lot of quality images. I searched "HIV structure" and then looked at the web addresses for a sense of which ones were coming from reputable science sources. (Ok, I'll admit. Sometimes I also went for the easy stuff.)
- I just started playing with the TRIP database. I've been working at UAB's medical school for a couple of years now, and they are focusing students on evidence-based medicine (the science behind good practice). TRIP is a database of evidence-based medicine, and I got several good hits when I initially searched on HIV there. An interesting feature is that it give patient information leaflets, which might help students who are asking, "Why do we need to know this?"
Enjoying Lesson Development
- Learning science: Inquiry often puts me in the learner mode because I'm having to think deeply about my understanding of the science involved as I try to represent it for my learners.
- Reflecting on standards: I have to often circle back to meaningful standards to make sure that I'm focusing my students on science that is meaningful to them. (Atlas for Science Literacy is my go-to set of standards.)
- Creative teaching: I love the creativity in developing good lessons. Don't all good teachers? I'm now working at a new level of creativity because I'm working to engage & sustain my students in rigorous inquiry.
- Lots of reflection: I'm always having to think deeply, either in lesson development or in teaching the lesson, about, "How is this going? Is it working? How do I know?" I enjoy that process.

Theory Supporting Inquiry
| Resource | For Inquiry Teachers | For GEC Participants |
| Key Research Supporting Inquiry’s Focus on addressing student misconceptions, facts aligned with big ideas, and use of conceptual change strategies. | This is the research that framed our face-to-face session. Start at the page linked here for the key research findings, but back up to the entire document (especially chapters 2 & 5) if you want to know more. | |
| Private Universe is a seminal video in science education because of how it communicated the prevalence and persistence of scientific misconceptions. Minds of Our Own took the same methodology and presentation style to content other than astronomy. | Assessing prior knowledge is the first step in authentic teaching and learning. These resources help you see more the power of student misconceptions by examining the blocks K-12 students face. | |
| Inquiry is difficult, if not impossible to accomplish, if teachers can’t manage effectively student work in small groups. Cooperative Learning, as described by the 5 Elements, defines true cooperative learning, which is very different from typical group work. | A first move many teachers make when beginning to implement authentic teaching is breaking large classes into small groups. The 5 Elements of Cooperative Learning give you a powerful way to think about how to do this successfully.. | |
| Atlas of Science Literacy (Original Version and Complete Version) | Why spend hours and hours trying to find the big ideas of science when this stellar work from Project 2061 has already done that. These maps show 100 grand ideas of science and how they should be developed across a students’ K-12 learning. | These big ideas from K-12 education give you strong examples of how big ideas can be used as a conceptual framework for learning the facts. For a different example, you may want to review UAB School of Education’s Conceptual Framework to see how we structured assessment of professional program around 11 big ideas (click the links there for rubrics). |
| Today’s K-12 students grew up with the Internet. They have no idea what life and learning are without it. This resource helps teachers understand how today’s students are different, not deficient. | Traditional-age undergrads and grads are used to learning with the WWW at their fingertips. The Introduction from this resources gives you powerful ways to understand these students, the challenges they face, and the strengths they bring to the learning environment. | |
| Other Inquiry Resources | I’m always collecting inquiry resources and posting them to this page. The first part of the page gives curriculum resources; the second give more general resources. | Inquiry is a model of authentic learning specific to science instruction. If you’re interested in learning more, start with the 5 Essential Features of Inquiry. |

Orlando High School Follow-Up
It was great being with you on Wednesday, and I hope the What and the Why of Inquiry was helpful to you as you think about how to strengthen the use of inquiry in your classes. Many of you seemed to be interested in the connections between inquiry and improved ACT scores. Click the title of this post to see the ACT's College Readiness Standards; you'll see the document that I popped up on the LCD.
Use the comment button below to let me know any questions or comments you have about our time together, and I look forward to the next time we get a chance to work on inquiry again.

ASTA Inquiry Follow-Up
Monday, September 29, 2008
ASTA
- At 10:30, I'll be presenting on teaching evolution to religious kids. This is the session I've done in the past on the topic, but I've updated it some to include the big ideas that I'm covering in the book.
- At 2:00, I'll present on the what and the why of inquiry. This is the same session on inquiry I've done several times, and if you heard it before, there's not a lot that's new. Feel free to come, though, especially if you want to share what's working on inquiry in your classroom.
