Conceptual Framework for New Science Education Standards, draft ready for our review

By Peggy Ashbrook

Science learning begins in early childhood.

Science learning begins in early childhood.


Teachers of K-12, including early childhood educators, we have until August 2nd, 2010 to comment on the preliminary public draft of the Conceptual Framework for New Science Education Standards
Here are a few paragraphs from the beginning of the document to get you interested:
“This document is an interim draft of a report from a committee of the National Research Council (NRC) on K-12 science education in U.S. schools. It is being made public so that the authoring committee can receive comments and suggestions from interested practitioners, researchers, and the public to inform its final product.” (first page of Memo)
[Peggy: They want to hear from us! Therefore the authors may be forgiven for staying within the K-12 scope by describing children who are “entering school” as being kindergarteners. In this preschool teacher’s view, children “enter” school the first time they are formally taught, at home, in preschool, or in kindergarten.]
“The conceptual framework in this report presents the committee’s vision of the scope and nature of the education in science and engineering that is needed in the 21st century. Thus, it describes the major scientific ideas and practices that all students should be familiar with by the end of high school. Engineering and technology are featured alongside the natural sciences in recognition of the importance of understanding the designed world and of the need to better integrate the teaching and learning of science, technology, engineering, and mathematics.” (Chapter 1, Introduction: A New Conceptual Framework, pg. 1-1)
 “The rationale for organizing content around core ideas comes from studies that show that one major difference between experts and novices in any field is the organization of their knowledge. Experts understand the core principles and theoretical frameworks of their field. Their retention of detailed information is aided by their understanding of its placement in the context of these principles and theories. Novices tend to hold disconnected and even contradictory bits of “knowledge” as isolated facts, and struggle to find a way to organize and integrate them. Learning to understand science or engineering in a more expert fashion requires development of an understanding of how facts are related to each other and to overarching core ideas. Research on learning shows building this kind of understanding is challenging, but is aided by explicit instructional support that stresses connections across different activities and learning experiences.” (Chapter 1, Introduction: A New Conceptual Framework, Understanding Develops Over Time, pg. 1-6)
[Peggy: Making connections may be easier in early childhood—before students have different teachers for different subjects.]
“As a result of our effort to identify fewer core ideas of science and engineering, some scientists and educators may be disappointed to find little or nothing of their favorite science topics included in this framework. The committee is convinced that by building a strong base of core knowledge and competencies, understood at a deep enough level to be used and applied, students will leave school with a better grounding in scientific knowledge and practices and greater interest in further learning in science, than those whose instruction “covers” multiple disconnected pieces of information, to be memorized and forgotten as soon as the test is done.” (Chapter 1, Introduction: A New Conceptual Framework, Selecting Core Ideas and Practices, pgs. 1-14 & 1-15)
[Peggy: Yes, let children work on a few topics or concepts for a long time to develop the deep understanding they are capable of. There are many favorites still in the mix.]
There are four grade level bands, K-2, 3-5, 6-8, 9-12. I have only taken a brief look at Chapter 3, Core Ideas and Chapter 7, Learning Progressions, (similar in structure to the conceptual strand maps in the Atlas of Science Literacy (AAAS)), and see that there is more than one progression for each branch of science, one for each Core Idea. I definitely need more time to read and think about this draft and may need to see it printed out to really be able to think about it.
Here’s one question I have:
Does the Life Science Core Ideas 1, or 3, (see below) need to add something about plants and animals needing access to air into the K-2 section? Maybe it is omitted because the concept of matter existing as a gas is not introduced in the Physical Science Core Idea progression until Grades 3-5 (also below). 
Growing bean plantOn page 7-9, Life Science (LS) Core Idea 1: Organisms have structures and functions that facilitate their life processes, growth, and reproduction.
Grades K – 2
How do living things meet their basic needs?
All living things have various external parts. Different animals use their body parts in different ways to see, hear, grasp objects, seek, find and take in food and move from place to place. Plants also have different parts that help them meet their needs.
On page 7-11, LS Core Idea 3: Organisms and populations of organisms obtain necessary resources from their environment which includes other organisms and physical factors.
Grades K – 2
Where do animals get food?
Animals depend on plants and other animals for food. When animals and plants (or plant parts) die, they are fed upon by tiny organisms that break them apart. Plants depend on air, water and light to grow.
On page 7-40, Physical Science (PS) Core Idea 1: Macroscopic states and characteristic properties of matter depend on the type, arrangement and motion of particles at the molecular and atomic scales.
Grades K – 2
What kind of parts are objects made of? (macroscopic)
Objects are generally made of different parts. The parts can be made of different materials. Materials can be natural or manufactured from natural resources. The identity, characteristics and function of an object depend on the materials/building blocks used to make it, and the way they fit together. The same materials can exist as a solid or a liquid depending on the temperature. Solids have a definite shape while liquids flow to the lowest level in the container.
Grades 3 – 5
How do the parts of an object affect its structure and function? (macroscopic)
All substances are considered matter. Matter can exist as solid, liquid, or gas. In all forms it can be felt and weighed. It is possible to break materials apart into pieces too tiny to see. However, the material still exists and continues to have weight even though we can’t see it. You can make a great variety of objects with just a few types of components. The structure, properties and uses of the objects depend on the nature of the components and they ways they attach to one-another, but can be quite different from those of the components. Knowing about the characteristics of materials helps design uses of them. Many substances can exist as solid, liquid or gas depending on the temperature. Solids have definite shape and volume, liquids also occupy definite volume, but not shape, gases are made of particles too small to see that move around throughout the full volume of any container.
Thank you to all involved in this important endeavor. Let’s take a close look and give the committee our feedback. A survey will be posted on July 14, 2010.

Summer sampler

I know that summer is well underway when I get my July issue of The Science Teacher with suggestions for new books to read, websites to explore, and topics to think about!
Call me a dinosaur, but to me there’s nothing better than curling up with a good book on a hot summer day—at the beach, by the river, in the park, or on the front stoop/porch. In addition to those novels I didn’t read during the school year, I’ve picked out a few science-related books form the recommendations in Kick Off Summer with Reading. (See A Diverse Summer Reading List in this month’s Science Scope for another list of suggested books). At NSTA Recommends, you can get the complete list.
The summer is not just for reading. This month’s Science 2.0 article Summer Surfing has a list of 21 free web tools to support learning. I’m familiar with and have used many of them (such as Google Docs, iGoogle, Inspiration, the NSTA Learning Center, and TED. But I made a little checklist for myself to look at the others. It’s unfortunate, however, that many of these tools are blocked in schools, requiring teachers to access them outside of school.

The author of A Virtual Circuits Lab shows how to extend students’ experiences beyond their elementary or middle school circuit-building activities. Using the simulation Circuit Construction Kit from the PhET collection of simulations (which can be downloaded or used online), his physics students explored and designed types of circuits. The author notes that “the simulations themselves do not make for a constructivist, inquiry-based lesson—the teacher must use these simulations as a tool for exploration and discussion. Lessons should allow for creativity and problem solving, instead of simple observation.”
I can spend hours at the PhET site! You can search the index of simulations by science content area or by grade level (including elementary and middle levels). Each animated simulation has teaching ideas and could be used by individuals or small groups or projected to a whole class. PhET is one of the many websites on Electronic Circuits in SciLinks.
Generate an Argument has step-by-step directions for implementing this type of activity to “discuss and critique the process, products, and context of an inquiry” and includes a lesson suggestion from the earth sciences. If you feel that you need to learn more about argumentation as an instructional strategies, check out the November 2009 issue of Science and Children for more examples.
I once observed a social studies class in which the students were investigating the technologies and inventions of the American industrial revolution of the late 19th century. I couldn’t help but think that this would have made a great interdisciplinary unit. The students in From Generation to Generation: Oral Histories of Scientific Inventions of the 20th Century learned about these inventions and technology directly from people in their community who had first-hand knowledge. My school had a “senior citizens” day every fall. Oral histories would have been a great activity. There are many sites that describe how to do podcasts (the free software Audacity is popular, but if you’re a little hesitant, ask some students to figure it out and teach the rest!  SciLinks has some websites with ideas in Technology and Human Culture.
I was disappointed to see that this was Alan Colburn’s last Prepared Practitioner column. I always enjoyed his concise look at connecting theory and practice. But fortunately, we have access to the NSTA archives to revisit his work. Thanks, Alan. Your column helped me to continue to be a “prepared practitioner.”
Check out the Connections for this issue. Even if the article does not quite fit with your lesson agenda, this resource has ideas for handouts, background information sheets, data sheets, rubrics, etc.

Is "connecting with nature" the same as "science"?

By Peggy Ashbrook

Posted on 2010-07-09

Children looking closely at a grub on a nature walk.Take a look at The ChildCare Information Exchange’s current “Insta-Poll” (a casual poll of readers) on their views on the Highest Priority Teacher Training Topics. “Connecting children with nature” is fifth in priority today when I looked at the poll, mentioned by 19% of the 263 people who had so far responded and “Science” is 42nd, tied with “Art” as mentioned by 3% of respondents. The Exchange publishes books, the Child Care Information Exchange magazine and the online ExchangeEveryDay daily early childhood newsbrief, and founded the independent non-profit organization, the World Forum Foundation, which runs a yearly conference on early care and education.
I think science walks and explorations, and making art would be excellent ways to connect children with nature. Perhaps taking nature walks would be a good first step in strengthening the science curriculum in early childhood programs.
The “Into the Woods” Teaching through Trade Books column by Karen Ansberry and Emily Morgan (Science and Children April/May 2007) describes how a class can explore a natural area outdoors, record their observations, and create a class book containing their own questions and answers about local wildlife (available at no cost online to NSTA members and to non-members after registration—scroll down to search).  “A Walk in the ‘Tall, Tall Grass’” by Kathryn Kaatz (Science and Children February 2008) describes an inquiry-based lesson (inspired by Denise Fleming’s 1991 book entitled, In the Tall, Tall Grass) that takes kindergarteners out on a nature walk to make observations and record them (available at no cost online to NSTA members and for $0.99 to non-members—scroll down to search).
An isopod, also called roly-polies, pillbugs, and potato bugs, on the sidewalk.Clouds can have interesting shapes.Children are thrilled by the smallest discoveries, such as a critter on the sidewalk or an interesting cloud. I’m wondering, can every walk can be a nature walk in early childhood or should some be specially for observing?

Safety information for teaching science

By Peggy Ashbrook

Posted on 2010-07-08

In planning for the school year, I check for safety considerations on the National Science Teachers Association website, at www.nsta.org/portals/safety.aspx#elem
Children wear safety goggles.Of course, each class of children is different, and I won’t know until September if any of the four-year-olds still put small objects in their mouths, or if any of the children have allergies. I’ll use the links to find safety guidelines, but once I know my class I’ll be able to know which hazards particularly apply to my students. Wearing safety goggles when working with substances such as Borax solutions which  might splash and get into children’s eyes is good practice but requires teacher vigilance to make sure children keep them on!
Some of the dangers I’ve seen occur (which I did not predict) are:

  • Children blowing into a plate of dry sand that we were looking at using magnifiers and getting sand in their eyes. Now I give children just a pinch of sand into their palms and caution them not to blow or it may get into their eyes. I could also have the children use safety goggles but they find it hard to use the magnifiers at the same time.
  • Children standing on a group of marbles (on purpose) and slipping. Now I only give out two marbles per child.
  • Children falling when they slipped on the edge of a scarf while dancing around a room with a tile floor. We moved the scarves to a carpeted area.
  • I forgot that a child had contact allergies to wheat and brought in a container of Tenebrio beetles and their babies (mealworms) which live in a bedding of oatmeal and wheat bran. Luckily another teacher remembered before I opened the container and the class just observed the insects inside.
  • Children flinging dirt up into the eyes of the next child. Now I model how to dig towards oneself before we hand out the large soup spoons we use as trowels. It also helps to enthusiastically say, “Oh look at all that good dirt you are digging up! Save that dirt right next to the hole so you can use it to put back around the flower bulb/roots after you plants.”

I hope you’ll share some safety tips with all the Early Years readers by commenting below.
Washing hands after handling dirt, or other substance which may have harmful bacteria, viruses, or molds, or animals such as guinea pigs or slugs, is one of the easiest safety precautions to put into use, but it does take time. It makes sense to have a sink in every early childhood classroom and two or three might be even better! Can you suggest ways to make hand-washing go faster or an activity to do while waiting to wash?

Re-grouping in the calm after the end of the school year

By Peggy Ashbrook

Posted on 2010-07-03

Seed sprouting experiment ended when water dried upSeed sprouting experiment comparing 3 different amounts of water.This past year I didn’t communicate well enough with some of the classroom teachers I work with so some science activities that might have been used sat on the shelf instead. Putting my efforts into doing science with the classes of children has introduced their teachers to many activities but has not developed the teachers’ knowledge of science inquiry as fully as I had hoped. So next year I plan to…..(“calm” is relative—at least the summer pace of re-thinking my science work, planning family gatherings and summer school attendance is less hectic than the weekly gathering of materials for upcoming activities and parent meetings that occur during the school year.)
Now I have more time for reflection on where I want to make improvements to the science instruction at the preschool programs I’m involved with. One school has already sent out an email requesting ideas for strengthening the curriculum for the upcoming school year. I would like to do a training in science inquiry with the classroom teachers so they can experience the process themselves away from children. Taking a professional development course about science inquiry in early childhood myself at the University of Northern Iowa is one way I’m going to develop my skills. My summer reading list has a few teaching-related items on it, including the short piece How toAsk the Right Questions by Patricia E. Blosser, a guide to evaluating your use of questions in the classroom and how the amount of time you wait for students to answer, and how long you wait to reply, affect the students’ learning. Summer issue cover of Science and ChildrenAnd I’m going to look for ways to collaborate close to home so I can learn all year long—your comments on the NSTA blogs and the discussions on the NSTA email lists always inform, and planning time with the other teachers in the school helps me reflect on what and how I teach. See the Summer 2010 issue of Science and Children for more ideas about how to make professional development work for you.

Green Science: How green is your lawn?

Science Scope—Summer 2010

The perfect American lawn—green, lush, weed- and pest-free—is pursued by millions of Americans, who expend a massive amount of resources to attain this ideal. Americans spend an estimated $25 billion a year on lawn care, and a one-acre lawn costs approximately $400–$700 a year to maintain (Bormann, Balmori, Geballe 1993; EPA 2009a). While lawn care seems to be just part of everyday life, the effects of lawn maintenance on the environment are not minor. This article will address the myriad effects of lawn maintenance and environmentally friendly alternatives.

Should We Continue Space Travel? A Technology-Supported Approach to Engaging Students

Science Scope—Summer 2010

It often seems that as the school year draws to a close, students lose their enthusiasm for learning. So the question becomes, how do we design meaningful curricula that places students at the heart of the learning? After all, intrinsically motivating young adolescents can be a challenge. In this article, the author describes how she addressed this challenge by designing a unit that takes into account students needs for socialization by utilizing a project-based, technology-supported space unit that incorporated student-centered instruction and hands-on exploration with blogging.

Free journal columns on early childhood science

By Peggy Ashbrook

Posted on 2010-06-29

Children and teacher discuss which objects might float and which might sinkIn the interest of making it easier for early childhood educators to teach science, I am unabashedly tooting my own horn—read the Early Years column I write in the National Science Teachers Association’s elementary school journal, Science and Children. Not an NSTA member? Some of the Early Years columns are available online to non-members at no cost in the NSTA Learning Center if one follows these steps:

  1. Create an account (no charge).
  2. Use the “advanced search” option.
  3. Search for “early years” as a keyword and “ashbrook” as author, and “free” as cost.

I think it will be worth your while to find columns about such topics as melting, inventing animals, and the sun’s energy. While you’re there take a look at some of the other benefits of membership. Members get one journal in the mail and online access to all four NSTA journals.
Is there a topic you would like me to write about in the Early Years column? Post a comment below and let me know.

A resource for new teachers

By Mary Bigelow

Posted on 2010-06-28

Congratulations to our new colleagues! Whether you’re a new college grad or changing to a new role as teacher, NSTA’s SciLinks can be a valuable resource for you. Through SciLinks, teachers and students can access vetted web pages that provide real-time information and new content on a host of science topics. The websites were selected and reviewed by a team of educators (aka “webwatchers”)  before being added to the database. Some are tagged as teacher resources if they address professional issues, instructional strategies, or lesson plan suggestions.
There are two ways to find websites in SciLinks:

  • Use the codes in a SciLinked textbook or NSTA publication. These codes usually appear in the margins.
  • NSTA members can search the site by keyword and grade level.

Once you find the websites related to your topic you can use them in several ways:

  • Recommending sites to students. As a teacher, you can provide logins for students to look at particular sites, or you can give them a list of suggestions from your “favorites.” For interested students, you could go to the next grade level to search a topic or go down a level for students who may struggle with the text. Share a login with the librarian so that he/she can remind students of this resource. If your students use the technology at the local public library, perhaps the staff there could be alerted to how and why students would access this.
  • In large group settings. Why just talk about science topics when there are many sites that lend themselves to illustrating the concepts? Building bridges, watching volcanoes erupt, seeing animals congregate around a water hole at night, or accessing videos and graphics of various topics bring these topics to life. If you have a smart board or projection unit, using a simulation or video clip with the class or a small group of students could be an engaging experience for them – and the resources are free and ready when you are. You can print some of the pages of a site to supplement or update textbook information.
  • Teacher learning. One thing I’ve enjoyed over the years is using the SciLinks websites to keep current on topics such as the human genome and climate change. I especially enjoy the earth science topics (I taught life and physical science, so I’m continuing to learn). If you’re unfamiliar with a topic, searching for sites geared to middle or high school students would be a quick and painless way to learn more about it.

Recently, a “Quiz Manager” feature was added in which you can create questions for a particular website in the SciLinks database and assign students to complete them. Click here to read more about this feature.

Congratulations to our new colleagues! Whether you’re a new college grad or changing to a new role as teacher, NSTA’s SciLinks can be a valuable resource for you.
