NGSS Breakdown: The Space Station View

I thought I'd write out a bit of what I understand about the Next Generation Science Standards (NGSS).  This is not even a birds-eye view of NGSS, it's the space-station view.  There are plenty of better reviews, but here's mine.

NGSS is based off of A Framework for K-12 Science Education, a brief 400 page explanation on how we need to be teaching Science, Technology, Engineering, and Mathematics, or STEM, from Kindergarten to 12th grade.

NGSS is intended to be a benchmark for the science that all informed citizens must know.  Not everyone needs to know the clotting cascade but everyone should know how to interpret a graph and understand basic ecology.  Students interested in honors and AP courses for college transcripts can still take them, but all students must meet the minimum NGSS Standards.

NGSS is concerned with these three branches of science:
  1. Earth Science - Earth & Universe, Earth's Systems, Earth and Human Activity
  2. Physical Science - Matter & its Interactions, Motion/Stability, Energy, Waves
  3. Life Science - Organic Structures, Ecosystems, Heredity, Evolution

NGSS Breakdown

NGSS delivery has 3 Dimensions:
  1. Dimension 1: Science and Engineering Practices - This is concerned primarily with what all students must be able to Know and Do.
    There are 8 subtopics
    1. Asking questions (for science) and defining problems (for engineering)
    2. Developing and using models
    3. Planning and carrying out investigations
    4. Analyzing and interpreting data
    5. Using mathematics and computational thinking
    6. Constructing explanations (for science) and designing solutions) for engineering
    7. Engaging in argument from evidence
    8. Obtaining, evaluating, and communicating information
  2. Dimension 2: Crosscutting Concepts - This is primarily concerned with Fundamental Questions and Bridging Concepts.  After all, you can't really teach biology without understanding basic earth and physical science.
    There are 7 subtopics
    1. Patterns
    2. Cause and effect: Mechanism and explanation
    3. Scale, proportion, and quantity
    4. Systems and System Models
    5. Energy and Matter: Flows, cycles, and conservation
    6. Structure and function
    7. Stability and change
  3. Dimension 3: Disciplinary Core Ideas -  This is concerned with Content delivered in a logical Progression. Here we get to specific science content.  In 1st grade, a student may learn about using their senses to tell whether something is warm or cool; in 11th grade, students may learn how to take the temperature of a substance using different thermal scales.
    There are 44 subtopics that I will not include here.  Take a look at how the core ideas are presented over a student's entire K-12 career: K-12 Core Disciplinary Ideas (.pdf)
Bozeman Biology has an excellent YouTube channel and a terrific website, BozemanScience.com, that offers a range of science-related videos.  Paul Anderson does a good job explaining NGSS and is in the process of producing individual videos on each aspect of the standards.  

I'm very optimistic about the state of science education once this is all rolled out.  At its core, NGSS works on leading students beyond data memorization and information regurgitation to critical thinking and problem solving.  The current No Child Left Behind (NCLB) standards are quite long in the tooth and NGSS is coming.  ...eventually.  ...maybe in 5 years.

Next Generation Science Standards: Hart District Teacher Symposium

While the students started their 4-day weekend, the teachers of the Hart District were at a buy-back day.  The theme of the Hart District Teacher Symposium was Common Core and, for science teachers, the Next Generation Science Standards (NGSS).



Dean Gilbert, Science Director for the Orange County Department of Education, ran the first session.  He spent a fair amount of time talking about the history of NGSS and its implementation.  I have heard some of what he talked about; we've been introduced to a lot of the NGSS theory in my credential classes.

The New

 Here a few of the things I learned:
  1. NGSS is a system of delivering science for all students.  NGSS does not address those students headed for a STEM careers (doctors, scientists, nursing, etc.)  Students pursuing those careers will still take honors and AP classes.
  2. Implementing NGSS will cost the state 3 times what it's costing to implement Common Core.
  3. There is a debate about how junior high teachers will implement NGSS.  Gilbert is leaning on teachers to adopt an integrated approach where teachers will deliver physical, earth, and life sciences in an integrated class.  Due to some backlash from teachers, the option to continue teaching the differentiated fields is on the table.  The decision will be voted on by current science teachers.
  4. What we have been calling "standards" (.pdf) will be replaced by "performance expectations."
  5. A body of experts are being gathered as I type to create the framework on which the curriculum will be based.  Should nothing go wrong, it will take at least 12 months to establish the science framework.  Add another 17 months for materials preparation, and we're looking at the earliest possible date for NGSS implementation is fall 2017.  

The Exciting

From Gilbert's talk, here are the things I'm really looking forward to:
  1. Anything not deemed important for all students to know about science will be removed from the curriculum.  No memorizing the details of the Kreb's Cycle anymore.  The voting public doesn't need to know this information to make informed decisions about science or environmental policy. The Kreb's Cycle will still be studied in honors and AP biology courses, so it won't totally be eliminated.  But, again, this course of study will be for those students pursuing STEM careers.
  2. By eliminating superfluous material in our courses, we can spend more time on inquiry, problem solving, and scientific literacy.  This is exciting.  Normal folks don't care much about the "mighty mitochondria," but most people have stuff they're curious about.  Helping students figure out how to do research, solve real-world problems, and communicate effectively is why I'm in the game. All this involves time, and it appears that by eliminating overly technical stuff, we've got some time back.
  3. The NGSS seems pretty student-oriented.  The needs of the 21st Century student came up a lot, and I think that NGSS should meet them nicely.
  4. Data and reflection are major drivers of NGSS.  One of the major problems with the current standards is that you've got to cover them all in a limited time frame; covering the standards trumps mastery of the standards.  And, anything you do to meet the standards is just fine.  This has led to a culture of "set it and forget it": teachers prepare lessons once and then they're on cruise-control until retirement. NGSS finally allows teachers the time to act on information gathered by good assessments.  When students display that they misunderstand a concept, the lesson for the next day can address it. Sadly, this type of teaching is rare, and I expect that this will be a point of contention for the old guard.
  5. Backwards planning is a major part of NGSS.  This is huge in the credential program, but is not done a lot in classrooms I have observed.  We do stuff because it's always been done that way.  

The Concerns

Here's what makes me hesitant about NGSS:
  1. Computer-based Testing - Gilbert was really excited about computer based testing.  Apparently Smarter Balanced didn't get the contract, and NGSS is looking at other options.  He mentioned that the California Department of Education would like to have lab simulations where students could virtually pour liquids into beakers.  I'm all about computer-based testing, but students who have not used computers regularly will be at a major disadvantage.  Students need to practice and be familiar with the technology to get the best results. Current computer labs are slow.  iPads and netbooks are expensive.  One major part of NGSS is equity, and I hope that lack of resources doesn't hinder scores on the computerized exams.
  2. Professional Development - There is concern about how to get teachers out of the old way of thinking and into the new.  Gilbert mentioned training programs and certifications, but these cost money and I don't see the public being that eager to foot the bill.
  3. Credentialing - There is a major emphasis on integration across fields of science.  Physical, earth, and life science are all interrelated, and the NGSS standards wants them integrated.  How they're integrated is a point of contention.  This will eventually change the credentials required of teachers.  No one has answers to these questions yet.
  4. NGSS and College Requirements - The subject of how high school science courses meet the requirements of colleges is squishy.  In my conversations with those who have dealings with curriculum development, the answers are not yet there.
But, when it's all said and done, I learned quite a bit today.  I have a better grasp of the near future and the goals of NGSS, and I'm optimistic about implementation.  There are unknowns and I'm okay with that.

Here, we're making Oobleck, a non-Newtonian fluid, to simulate an inquiry-based, NGSS-compliant task.
