The NGSS Crosscutting Concepts ARE Science Content!

“How come if people evolved from monkeys, monkeys aren’t turning into people now?”

Evolution-Ahearn-1

I’m going to bet that any science teacher who has taught evolution has run into this question at some point. There are a bunch of incorrect assumptions behind the question, including the idea that evolution is a process that we could observe occurring during our lifetimes. This idea is directly addressed as part of the NGSS Crosscutting Concept of Scale, Proportion, and Quantity with the idea that:

  • Phenomena that can be observed at one scale may not be observable at another scale.

and

  • Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.

(Note that this is not the crosscutting concept called out in the middle school evolution topic. Teachers will need to used multiple crosscutting concepts as well as multiple practices in building coherent units – not just the ones highlighted in the standards).

What can you see when you look at things at a different scale?

What can you see when you look at things at a different scale?

Evolutionary change only becomes observable when we look at time scales that dwarf a human life. If students don’t understand that, they will make assumptions like those behind the monkey question. The idea that we see different things at different scales is basic to many science ideas (chemical reactions, geology, astronomy, cell biology), which is why it is directly addressed in the NGSS. This idea appears in the NGSS as part of the middle school content for the Crosscutting concepts.

Confusing and incorrect logo- there is “content” in all three dimensions.

“Wait a minute”, I can hear you saying, “aren’t the Disciplinary Core Ideas the content in NGSS?” Some versions of the NGSS logo imply that.

Correct logo- all three dimensions are “content!”

Correct logo- all three dimensions are “content!”

Actually, if you read carefully you will find that there are specific content ideas within the Crosscutting Concepts AND the Science and Engineering Practices. A easy to read list can be found at: http://nstahosted.org/pdfs/ngss/MatrixOfCrosscuttingConcepts.pdf.

This may help teachers who find the crosscutting concepts to be interesting, but sometimes a little vague. There are specific ideas behind them and those ideas should be directly addressed in a lesson sequence that contains that crosscutting concept.

If you are looking for questions to guide your lesson, check out the critical questions at the Crosscut Symbols website at http://crosscutsymbols.weebly.com/ . For example, when discussing geologic (and evolutionary) time, a good starting question with students could be: How does this scale relate to you? How much bigger is it than what you are used to experiencing? Like most questions about scale, it takes some math to answer. In finding the answer, students will understand that the scale of evolutionary change is much larger than the scale of our lifetimes.

  1. Actually, evolution can be demonstrated within a school year using short lived species such as fruit flies or fast growing plants. This sort of experimental approach really gets into the science of science. You could even use rats to demonstrate the epigenetic consequences of stress and obesity in offspring, but there would be ethics concerns.

  2. Thank you Pete for the great resource and providing a deeper perspective regarding on cross-cutting concepts. I get the monkey question on a a regular basis!

Participate in Chemistry Education Research Study, Earn $500-800 Dollars!

Posted: Tuesday, May 9th, 2017

WestEd, a non-profit educational research agency, has been funded by the US Department of Education to test a new molecular modeling kit, Happy Atoms. Happy Atoms is an interactive chemistry learning experience that consists of a set of physical atoms that connect magnetically to form molecules, and an app that uses image recognition to identify the molecules that you create with the set. WestEd is conducting a study around the effectiveness of using Happy Atoms in the classroom, and we are looking for high school chemistry teachers in California to participate.

As part of the study, teachers will be randomly assigned to either the treatment group (who uses Happy Atoms) or the control group (who uses Happy Atoms at a later date). Teachers in the treatment group will be asked to use the Happy Atoms set in their classrooms for 5 lessons over the course of the fall 2017 semester. Students will complete pre- and post-assessments and surveys around their chemistry content knowledge and beliefs about learning chemistry. WestEd will provide access to all teacher materials, teacher training, and student materials needed to participate.

Participating teachers will receive a stipend of $500-800. You can read more information about the study here: https://www.surveymonkey.com/r/HappyAtoms

Please contact Rosanne Luu at rluu@wested.org or 650.381.6432 if you are interested in participating in this opportunity, or if you have any questions!

Lessons Learned from the NGSS Early Implementer Districts

Posted: Monday, May 8th, 2017

On March 31, 2017, Achieve released two documents examining some lessons learned from the California K-8 Early Implementation Initiative. The initiative began in August 2014 and was developed by the K-12 Alliance at WestEd, with close collaborative input on its design and objectives from the State Board of Education, the California Department of Education, and Achieve.

Eight (8) traditional school districts and two (2) charter management organizations were selected to participate in the initiative, becoming the first districts in California to implement the Next Generation Science Standards (NGSS). Those districts included Galt Joint Union Elementary, Kings Canyon Joint Unified, Lakeside Union, Oakland Unified, Palm Springs Unified, San Diego Unified, Tracy Joint Unified, Vista Unified, Aspire, and High Tech High.

To more closely examine some of the early successes and challenges experienced by the Early Implementer LEAs, Achieve interviewed nine of the ten participating districts and compiled that information into two resources, focusing primarily on professional learning and instructional materials.

Using Online Simulations to Support the NGSS in Middle School Classrooms

Posted: Monday, May 8th, 2017

by Lesley Gates, Loren Nikkel, and Kambria Eastham

Middle school teachers in Kings Canyon Unified School District (KCUSD), a CA NGSS K-8 Early Implementation Initiative district, have been diligently working on transitioning to the Next Generation Science Standards (NGSS) integrated model for middle school. This year, the teachers focused on building their own knowledge of the Science and Engineering Practices (SEPs). They have been gathering and sharing ideas at monthly collaborative meetings as to how to make sure their students are not just learning about science but that they are actually doing science in their classrooms. Students should be planning and carrying out investigations to gather data for analysis in order to construct explanations. This is best done through hands-on lab experiments. Experimental work is such an important part of the learning of science and education research shows that students learn better and retain more when they are active through inquiry, investigation, and application. A Framework for K-12 Science Education (2011) notes, “…learning about science and engineering involves integration of the knowledge of scientific explanations (i.e., content knowledge) and the practices needed to engage in scientific inquiry and engineering design. Thus the framework seeks to illustrate how knowledge and practice must be intertwined in designing learning experiences in K-12 Science Education” (pg. 11).

Many middle school teachers in KCUSD are facing challenges as they begin implementing these student-driven, inquiry-based NGSS science experiences in their classrooms. First, many of the middle school classrooms at our K-8 school sites are not designed as science labs. Learn More…

May Through July 2017 with Web Resources for the Solar Eclipse of August 21, 2017

by Robert C. Victor. Twilight sky maps by Robert D. Miller. Graphs of planet rising and setting times by Jeffrey L. Hunt.

In spring and summer 2017, Jupiter is the most prominent “star” in the evening sky, and Venus, even brighter, rules the morning. By mid-June, Saturn rises at a convenient evening hour, allowing both giant planets to be viewed well in early evening until Jupiter sinks low in late September. The Moon is always a crescent in its monthly encounters with Venus, but is full whenever it appears near Jupiter or Saturn in the eastern evening sky opposite the Sun. (In 2017, Full Moon is near Jupiter in April, Saturn in June.) At intervals of 27-28 days thereafter, the Moon appears at a progressively earlier phase at each pairing with the outer planet until its final conjunction, with Moon a thin crescent, low in the west at dusk. You’ll see many beautiful events by just following the Moon’s wanderings at dusk and dawn in the three months leading up to the solar eclipse. Learn More…
