Middle School Integrated Science – Get Over It

Posted: Tuesday, June 3rd, 2014

by Pete A’Hearn

Okay, let’s face it, you are eventually going to the California integrated middle school progressions under NGSS. Time to get over it and start to plan the path forward. (Note: this is my opinion and not the opinion of CSTA.)

Why am I so sure? Because I have looked at the two possibilities closely and once you have, it’s a no-brainer. Here is the domain specific model:

Summary of Domain Specific Learning Progression for Middle Grades adopted by the California State Board of Education.

Summary of Domain Specific Model adopted by the California State Board of Education.

Wait a minute, what’s up with all of the content being shoved into 6th grade? Well domain specific means that Earth and Space Sciences is in 6th grade, and there is lots of content in Earth and Space Science. Much of it is developmentally inappropriate for 6th graders who will be challenged with the huge time and special scales encountered in Earth History and Astronomy. There is also the background in physics needed to understand how things move in space that requires some of the physics in 8th grade. Also, tracking how matter like carbon and nitrogen flow cycle through ecosystems at 7th grade requires an understanding of chemical reactions that students won’t get 8th grade. So why did the Science Expert Panel come up with this model? The answer is that they didn’t – they presented three possible sequences with their strengths and weaknesses and the CDE had a public survey to choose the most popular one. Teachers overwhelmingly chose Earth, Life, Physical, which they might have thought means the same as we have now. It does not.


Here is the integrated model:

Summary of Preferred Integrated Middle Grades Learning Progression Adopted by the California State Board of Education

Why did the Science Expert Panel favor the integrated model? There were several reasons: Integration shows that real world science is integrated, meaning that real world problems need ideas from different disciplines to be solved. Integration helps make the crosscutting concepts more central (the second box at the bottom). Integration helps create stronger storylines (see my article in CCS last month). Much content in Earth and Life requires physical science as background, such as forces for astronomy, chemistry for ecosystems, etc…, and as already discussed, 6th graders are typically not developmentally ready for astronomical scale and geologic time. There is also the issue of needing chemistry to understand ecosystems and physics to understand astronomy. There is a complete rationale for the CA integrated science model at:

Based on this evidence, the teachers in my district (Palm Springs Unified School District) were able to come to a consensus that integrated was the best way forward for our students.

Okay, so you are going to go integrated, but it can’t happen all at once – you don’t have curriculum materials, you need content training for your staff, and most importantly you want to make sure there are no major gaps in the content that your kids get. If you switch all at once in one year, there will be a group of kids that completely miss middle school chemistry and will take high school classes like biology and chemistry with no foundation. You need a plan that makes gradual changes over several years and gives people time to find materials and learn new content. There are probably many ways to do this, but here is a pathway that we looked at in Palm Springs:

Four-Year (“Slow”) Integrated Middle Grades Science Sample Implementation Plan

For clarity, I have used the names for units used by the Science Expert Panel. The (G) stands for genetics, which will end up spread out between 6th and 8th grade, and (EH) stands for earth history which will be divided between 7th and 8th over time. To understand what a student will experience you have to move diagonally and down through the chart. This is the reason that some subjects are taught at two grade levels in some years. For example, in year 3 chemistry is taught in 7th and 8th grade, ensuring that all students get chemistry. It also allows the new NGSS chemistry unit to be taught at 8th grade first, then refined and adjusted before the 7th grade teacher (new to this content) teaches it. The 7th grade teachers will have the support of the 8th grade teacher on their site teams when it their turn to teach chemistry. The same reasoning applies to the cells and organisms unit at 6th and 7th grade. This plan also allows for teachers to switch grade levels- possibly at the trimester- if they choose to remain “content experts” within the integrated model. So, a current 8th grade teachers could (in year 4) teach chemistry to 7th graders during the first trimester and then switch to 8th grade for the rest of the year. This is a possibility for sites where teachers feel very content specific.

After consideration of this plan the Palm Springs teachers chose to move faster rather than slower, and by consensus adopted the plan below:

Three-Year (“Fast”) Integrated Middle Grades Science Sample Implementation Plan

Don’t take my word for it. Do some close reading about the two models and take the time to think about how to make the transition work for your site, teachers, and kids. Happy Integration!

  1. As a middle school teacher I have a few big problems with the integrated model. Primary among them is my students’ math abilities. If you feel there is a problem with the math and astronomy, how about balancing chemical equations in the 7th grade. I know that under the assessment portion it says that students do not need to know that specific skill. At the same time the standards do say that students will need to understand that the same number of atoms are present both before and after a chemical reaction. To me, that is basically balancing equations and understanding conservation of matter and energy. Talk about some deep thinking. Perhaps students in certain parts of the state will be able to take it all in at the 7th grade level, but many will not. It also bothers me that the concept of Conservation of Mass is not revisited in the 8th grade. Hopefully there is still some fluidity to the standards so that as we run into kinks we can make adjustments. We are science afterall and the research and hypothesis sound good. If after we run our experiment we come back with the findings that our hypothesis is flawed, we will continue with the flawed model or adjust our hypothesis and try again? Thank you for providing a forum for my little rant, I greatly appreciate it. Hopefully, the powers that be will consider some of these concerns.

  2. Love your article, Peter. We are, as I write, using it to help us plan some summer PD 🙂

  3. No working scientist I know thinks the elementary-school style “preferred” science model is good for middle school. And as it happens we have regular interaction in our district with scientists (and their children ) rom Caltech and JPL/NASA just as a start. The only point I will agree with is that the state Board of Ed absolutely failed in their stakeholder outreach, and that a small group at the state level has this elementary style science as their top priority. As a result, when serious questions were raised about both the content and process the Board was embarrassed enough to rethink the process, and throw a bone on the content.

    Was the “alternative” strand stacked to make it unappealing to districts and unworkable ? You bet. Will elementary school “potpourri” science be forced on Districts? You bet. Does that make it right ? No.

    I don’t have a problem teaching NGSS as cast at the national level; and I AM working on PD this summer to help my colleagues adapt to — and not subvert — the poor Californis framework.

    That it is inevitable does not mean anyone should role over and accept bad educational policy.

  4. As an aside, it makes most sense (if one is yielding to the inevitable) to teach old content on new standards, but roll into the new content one grade level at a time. Thus, year one 6th Grade would do full “potpourri” model, while 7th and 8th would do 98 content / new standards; year two, 6th and 7th grade, do full “potpourri” etc. This way you avoid a group of kids that have had content shifted away from them so they never get it at all, but teachers get experience with implementing the new performance based model immediately.

  5. “Much it is developmentally inappropriate for sixth graders who will be challenged with the huge time and spatial scales involved with earth science and astronomy.”

    What is the evidence for this? 8th graders are challenged by this. Adults (including scientists are challenged by this). Just because it’s challenge to grasp these scales as human beings doesn’t mean it’s developmentally inappropriate for sixth graders. Link to research showing specifically this is developmentally inappropriate for sixth grade and not eighth?

    Why not simply move astronomy to 8th grade in the domain specific model as it is now? Physics, chemistry, and astronomy integrate quite well! And a foundation in physics (forces, energy) is really necessary to understand chemistry. We should build a solid foundation for high school chemistry in 8th grade, not dilute the subject in 7th grade (as would likely happen with the integrated model).

    It is not necessary to have very much knowledge of chemistry to understand the general concept of cycling in ecosystems. Leave the chemical equations for 8th grade, where they belong developmentally.

    I have serious doubts that the “integrated” model will enhance student learning. I have no doubt it will (if implemented) cause a great deal of time and energy to be expended on a dubious experiment.

    By the way, I am one of the early implementers of NGSS practices. I have been involved in IMSS in the bay area the past for years developing curriculum that is NGSS and common core aligned. The instructional shifts and including engineering are great; let’s not ruin it with this so-called “integration.” It’s too much all at once, and a recipe for wasted resources and gaps in student knowledge critical for high school success. Focus on the practices, the content will take care of itself!

  6. Mr. A’Hearn,
    With all due respect, we are not getting over it. As a department, middle school science teachers in our district took the approach of limiting bias and really look at what the state was offering with the integrated model. As much as we tried to see real integration and purpose in the division of the curriculum, we came to agree that the deciders used a false measure to use for integration. It became clear that they divided up the crosscutting concepts that they saw as easiest (patterns and structure/function for instance) and put the science topics that they thought best fit that model in 6th grade. Move on to more difficult cross cutting concepts in 7th and then eighth grade. NGSS in its original writing for the nation did not dilute these concepts. The intent was for these ideas to be inherent in all of science to different degrees. California has apparently decided that some of those concepts are less important and less difficult than others.

    A topic like cells and organisms, for example, seems to fit we’ll into patterns and structure/function for 6th grade, but disregards the lack of readiness and maturity needed for reproduction of organisms. Some of the state’s 6th graders are in elementary schools; even the ones in a middle school settings are much less mature than their upper grade counterparts. Not to mention the parents who are going to balk at teaching lessons on reproduction to their children at such an early age. By dividing each area of science into little bits for each grade, the completeness of the topic is watered down and limited, not allowing students to see how far reaching and predictable science is.

    I am offended that you belittle teachers who differ with your opinion throughout the state. Teachers know that all science needs to be integrated. That is why heat transfer needs to precede weather and orbits become part of Earth and Space science. I would have gladly considered a truly integrated model that made sense. For this reason our teachers with the districts approval have pulled in a few topics across the grades to round out the topics that have no foundation as the DCI model is written.

    I am disappointed in the county offices and California Science Project universities for being so quick to assume the state got it right. There was not adequate time for teachers to assess the ideas and weigh in. We have rejected the integrated model and are implementing a 3 year transition that begins in the 2014-15 school year. Grades seven and eight will be making NGSS and CCSS changes immediately where the science continues in that grade. We are extremely excited about the engineering and human impact additions and the move toward more inquiry and real-world applications. It is exciting to teach students as a facilitator and partner instead of the keeper of all knowledge who gives the multiple choice test. Formative assessments, student choice in learning, technology integrated throughout, and problems to identify and solve. Our students will be ready to be thinkers and doers who know how to weigh the pros and cons of human impact. There is hope for the future.

  7. I apologize for the typos that were difficult to find on such a lengthy message from an iPhone.

  8. We’ll said. I am interested in knowing where your work with early implementation of NGSS can be viewed.

  9. This is my fourth year teaching but I come from 25 years of experience as a scientist in environmental testing, assessment, and cleanup. My main concern is the lack of data-driven decisions in education policy – especially science education policy. Where is the data that shows that dividing up science subjects like biology and earth science over 3 years works for 11-14 year olds?

    My own experience is that in 8th grade we work hard to connect the subject material throughout a school year and that 8th graders (the oldest and most mature middle school students) struggle more than succeed with this task. Thus we have to recognize that there are limitations at this age and that expecting students to retain and connect information over 3 years is unlikely to be successful. As other commenters have noted, middle school science will be watered down and students will come into high school classes in biology and chemistry even less prepared.

    I also find it interesting that no one acknowledges that there is already a LOGICAL INTEGRATION of science topics in middle school. Speaking directly to Mr. A’Hearn’s comment – why does Mr. A’Hearn (and the rest of the state) believe it was only choice of “subject only” or “new integration only”? Why this false dichotomy? Why not the integration we already have? In 8th grade we currently teach chemistry, physics, and astronomy – all science that requires strong math skills and even in 8th grade the students that struggle in math will also struggle in science. Whether or not chemical equations are balanced in 8th grade, one has to recognize that chemistry and astronomy are more abstract sciences because we can’t directly observe the science (atoms, size/scope of universe) and even 8th graders struggle with this challenge. Sixth grade currently teaches earth science along with closely related energy concepts (for plate tectonics and weather) and ecosystems (for natural resources and human impacts). Seventh grade currently teaches biology along with closely related geological record concepts (for evolution) and light/lever concepts (for body systems like eyesight and muscular system). Our current system is THOUGHTFULLY INTEGRATED with RELATED science and with math readiness in mind.

    As to what our current testing data shows: under the current standards the middle school science program have been significantly more successful than elementary school and high school science programs. Looking at the statewide science CST data from 2014, middle schools achieved 66 percent of its students at proficient or advanced. In comparison elementary schools achieved 60 percent of its students at proficient or advanced.

    In high school the results are markedly lower with only two subjects achieving more than 50 percent of their students at proficient or advanced. High school life science achieved 56 percent and physics achieved 53 percent of its students at proficient or advanced (physics data is from 2013 – not tested in 2014). Looking at the proficient and advanced students in other high school subjects, biology achieved 49 percent, chemistry 40 percent, earth science 37 percent, and integrated science tested in 9th through 12th grade at 7-24 percent (note these data are from 2013, as they were not tested in 2014). From this data it is hard to argue that the largest changes are needed in middle school science. But then ed policy is not data driven, is it?

    And another point from this same data – the worst results are from high school integrated science, a class that teaches a collection of unrelated science concepts. Not only does this class produce very few students at proficient or advanced, students actually score lower in science after this class (so its outcome is the opposite of learning!). Strangely this is the exact model that middle school is being asked to follow – the new integrated model takes pride in teaching a collection of unrelated science together vs. our current model of integrated but RELATED science.

    Education policy should be based on data – assessment and observation, and then through analysis – identify what works, what needs improvement, and how to use the newest findings (NGSS recommendations) to gain the most improvement. Imagine if science did what science education policy does – we would just periodically throw out the current theory, keep nothing that worked, identify nothing that needs improvement, and start over from the beginning, blind to our past. Small wonder that science advances, and science education does not.

  10. Thank you for a well supported, thoughtful response. I am also concerned that California felt it appropriate to only change the delivery of NGSS DURING MIDDLE SCHOOL YEARS! It makes no sense to find what they obviously thought was a better plan and just apply it to middle-school-aged students.

    I will be sharing your response with my county and district superintendents because of the sound arguments that you have validated.

Thriving in a Time of Change

Posted: Wednesday, September 13th, 2017

by Jill Grace

By the time this message is posted online, most schools across California will have been in session for at least a month (if not longer, and hat tip to that bunch!). Long enough to get a good sense of who the kids in your classroom are and to get into that groove and momentum of the daily flow of teaching. It’s also very likely that for many of you who weren’t a part of a large grant initiative or in a district that set wheels in motion sooner, this is the first year you will really try to shift instruction to align to the Next Generation Science Standards (NGSS). I’m not going to lie to you, it’s a challenging year – change is hard. Change is even harder when there’s not a playbook to go by.  But as someone who has had the very great privilege of walking alongside teachers going through that change for the past two years and being able to glimpse at what this looks like for different demographics across that state, there are three things I hope you will hold on to. These are things I have come to learn will overshadow the challenge: a growth mindset will get you far, one is a very powerful number, and it’s about the kids. Learn More…

If You Are Not Teaching Science Then You Are Not Teaching Common Core

“Science and Social Studies can be taught for the last half hour of the day on Fridays”

– Elementary school principal

Anyone concerned with the teaching of science in elementary school is keenly aware of the problem of time. Kids need to learn to read, and learning to read takes time, nobody disputes that. So Common Core ELA can seem like the enemy of science. This was a big concern to me as I started looking at the curriculum that my district had adopted for Common Core ELA. I’ve been through those years where teachers are learning a new curriculum, and know first-hand how a new curriculum can become the focus of attention- sucking all the air out of the room.

Tools for Creating NGSS Standards Based Lessons

Posted: Tuesday, August 29th, 2017

by Elizabeth Cooke

Think back on your own experiences with learning science in school. Were you required to memorize disjointed facts without understanding the concepts?

Science Education Background

In the past, science education focused on rote memorization and learning disjointed ideas. Elementary and secondary students in today’s science classes are fortunate now that science instruction has shifted from students demonstrating what they know to students demonstrating how they are able to apply their knowledge. Science education that reflects the Next Generation Science Standards challenges students to conduct investigations. As students explore phenomena and discrepant events they engage in academic discourse guided by focus questions from their teachers or student generated questions of that arise from analyzing data and creating and revising models that explain natural phenomena.
