Designing Effective Science Instruction: What Works in Science Classrooms

Science teachers, like all teachers, start each school year with high hopes and expectations for students to succeed. They plan their lessons, scramble to get the necessary equipment, and work hard to engage their students. However, despite good intentions and best-laid plans, not all students do well in science classes, and even fewer achieve mastery. Student performance on national and international assessments is poor, and/or more adults are unable to understand the scientific issues that affect their lives and society.

Forestry Field Studies: A Manual for Science Teachers

Why forestry field studies? As experienced teachers of scientific ecology and forestry concepts, we believe that a forest or woodlot can provide teachers and their students with the perfect laboratory for understanding some of the basic principles of environmental science and community ecology. These studies were designed and used for many years as a unit in an advanced placement environmental science course. They also could be used as a lab in a biology, botany, forestry, or ecology class at the high school or beginning college level.

Lecture-Free Teaching: A Learning Partnership Between Science Educators and Their Students

Lecture-Free Teaching: A Learning Partnership Between Science Educators and Their Students provides readers with an innovative alternative to routine lecturing. With the Lecture-Free Teaching method, teachers build “learning partnerships” with their students to create more flexible, cooperative learning environments. These partnerships lead to engaged students who participate and share ideas through discussions and in-class activities, such as inquiry-based exercises and case studies.

Guest Editorial: Physics or stamp collecting? Pitfalls of the hierarchy of disciplines

Science Scope—November 2009

In science and in academia, there is often a de facto hierarchy of disciplines with the so-called “hard” sciences (physics, chemistry) at the top, and the “soft” sciences (psychology, sociology) at the bottom (Tudge 2001; Feynman 1988). As science educators, we may find ourselves consciously or unconsciously communicating this to our students, sending messages that certain scientific disciplines are more difficult or more important than others. In doing so, we may unconsciously be erecting barriers to some of our students and interfering with our goal of scientific literacy for all.

Urban science educators share strategies

October 30—It is Friday but I must tell you about the Urban Science Education Leaders (USEL) event.  It was very exciting! Why? The participants were so engaging and really were looking for information and answers and just wanted to learn and see more.  They began with the chair of the Urban Science Education Leaders presentation.  Dr. Bobby Jean-Pierre has amassed research over the last 10 years on how to better engagement between administrators and teachers.  Her studies and survey showed that allowing teachers a stake in the process was the most effective approach.  She spoke passionately as an educator and as a parent who wanted to see all children succeed.
Dr. Jean-Pierre also challenged the participants to look at this whole process of teaching inquiry.  What does inquiry look like in the classroom? One teacher from a small area in Minnesota asked about the time it takes to teach inquiry, which is a technique that has been found to be most effective in teaching science to students.  Basically, the students are guided to ask questions, find evidence, and make deductions. It is an engaging way to involve students and make science interesting because it allows the students natural curiosity to lead them in the process. This sparked a lot of discussion and led to our tour of two schools that have some innovative approaches to teaching science.
The first school Battle Creek Middle School uses the single gender approach and with great success.  They have common time for the boys and girls to mingle but the classes are all single gender.  The premise is that girls and boys process information differently, so their teachers prepare the lessons in science using inquiry and the natural strengths of the gender they are teaching.  The girls classes are more ‘chatty’ and the boys classes a bit calmer.  The USEL participants were able to talk with the students and watch the classes and make observations.
The second school, Washington Technology Magnet Middle School, uses the BioSmart model and introduces the students to three strands, Bio Medical and Health Services, Bio Engineering and Technology, and Bio Communication (Business and Marketing).  It is a high-tech approach with practical applications and allows students to follow a path in one of those areas more intensely in high school if they so choose.  This gives them practical skills and promotes critical thinking and analysis.
As an example, they have a shop class, but it is not like the wood shop class of old.  The students design their projects using AutoCAD, a design program used in industry.  They then take their design and build it in the wood shop studio and test it.
When we returned from the tour the principals of the two schools came and answered questions.  The discussion was lively and interactive and the participants really grilled the principals on every aspect of their programs. Then the science coordinator and the STEM coordinator presented an education overview of Minnesota, focusing on urban challenges. It was insightful to see how they had and continue to make the adjustment to address the changing demographics and the new challenges that come from a diverse demographic.
For the first time in the history of the state, they are getting an influx of very diverse populations looking for a new life. Language barriers as well as cultural and economic barriers are difficult, but the state of Minnesota educational system has implemented many steps and programs to assist their educators in handling the transition, so students are not lost in the system. It was an inspiring, informative and instructional day. This is a wonderful program; the participants appreciated the dialogue, the information and most of all the sharing with colleagues. We had three teachers from Canada and their system is different but they saw a lot of informative approaches and shared with other teachers. They were really excited. We look forward to more from this program.

Dark matter, dark socks

By Lynn Petrinjak

Posted on 2009-10-30

Seeing might be believing, but sometimes it’s what can’t be seen that’s most interesting. Since the 1930s, researchers have theorized that dark matter—which can’t be perceived by our eyes—is responsible for anomalies in the rotation of galaxies and other phenomena. Maybe it can account for socks vanishing from the dryer, or would that be a black hole? At the NSTA Conference on Thursday, conference attendees got a chance to see how they can make dark matter work in their high school classes when Nancy Bynum shared tips on Using Dark Matter to Teach Physics Concepts. “Dark Matter can be used to teach uniform circular motion, universal gravitation, two dimensional collisions, nature of science and technology as well as Newton’s second law,” says Bynum. Although there isn’t any direct evidence that dark matter exists, many physicists think it does. Bynum didn’t offer conclusive evidence of dark matter, but during the session, she shed light on a topic that leaves many students in the dark. Let me know if you find any stray socks.

Great science in urban middle schools

By Debra Shapiro

Posted on 2009-10-28

Minnesota Dept of Education logoIf you’re an administrator in an urban middle school, come to the NSTA Conference in Minneapolis. You can spend a day with a group of dedicated urban science educators—the Urban Science Education Leaders (USEL)—who are working to change the way science is taught in urban schools. One neat thing about this workshop is it includes visits to Minneapolis/St. Paul middle schools where you can see best practices in action.

For example, Battle Creek Middle School has achieved success by organizing students into single-gender academies and using the latest research when developing lesson plans and activities. At Hazel Park Middle School Academy, the staff is implementing an innovative Professional Learning Community and grading system based on the work of author and educator Richard DuFour.
You have to preregister for this October 28 event, which will also feature presentations from the Minnesota Department of Education’s science and STEM directors.

SciLinks and cooperative learning

By Mary Bigelow

Posted on 2009-10-28

Earlier this month, I was asked to search for and upload resources on cooperative learning for SciLinks (use the keyword “community collaborations”). There were many good sites, although some were published in the 1990s (interesting but a bit outdated) and were therefore not added to SciLinks. However, I found some newer sites that would be useful as a refresher, to find some new ideas, or to get started with this effective instructional strategy
Powerful Learning: Studies Show Deep Understanding Derives from Collaborative Methods was recently published on the Edutopia website. The authors (Brigid Barron and Linda Darling-Hammond) summarize research findings and provide examples of student collaborative projects. Download their expanded article Teaching for Meaningful Learning for more information (including links to video resources) and for a list of research studies and other professional writing on the topic.
The Science Education Resource Center (SERC) at Carleton College has an excellent resource “Teaching Entry Level Geoscience.” Although it’s designed for teachers of undergraduate courses, the teaching strategies are applicable to younger students as well (and include descriptions of gallery walks, field labs, role-playing, teaching with Google Earth, and others). The section on Cooperative Learning has lots of suggestions on this topic.
Cooperative and Collaborative Learning is a resource from WNET Thirteen Ed Online in its Concept to Classroom project. The four parts of the site guide the user through background information and suggestions for implementation: Explanation, Demonstration, Exploration, Implementation. Throughout this site, the emphasis is on real classrooms and includes ideas for assessment and a discussion of some challenges that might be encountered. There are video clips of actual classrooms (including science classes) using cooperative learning, too.

Are children getting enough direct experience with natural materials?

By Peggy Ashbrook

Posted on 2009-10-25

There has been an interesting discussion going on among the middle and high school science teachers on the NSTA General Science email list about the lack of direct experience in their students’ background. Some have suggested that early childhood and elementary schools are not laying the groundwork for the later learning.
One teacher said, “I was talking to an honors ninth grade class and most of the students said they had not seen a live grasshopper. This explains why several schools have started their biology classes with the ecosystems because they want students to be able to see and experience life sciences before moving to conceptual ideas in biochemistry and genetics.”
The National Science Education Content Standards (A and C) for K-4 call for all students to develop:

  • Abilities necessary to do scientific inquiry
  • Understanding about scientific inquiry

and

  • The characteristics of organisms
  • Life cycles of organisms
  • Organisms and environments

I know grasshoppers from a childhood field—with two visible bulbous eyes, pincher-like mouthparts, barbs on the hind legs, and wings that you don’t notice until one goes zooming past you. And they spit tobacco! At least that is what we called the “partially digested food material along with some semi-toxic compounds from the insect’s crop region.” It stained our palms when we held a grasshopper too tightly. Have your students had that experience?

Children are fascinated with beetles and other small animals.


I’ll share this comment with the early childhood teachers I work with to let them know how vital the experiences they make happen, or take advantage of, are to their students’ future learning. It may inspire us to take walking fieldtrips to a nearby field or brush at the edge of a parking lot to look for wildlife, or encourage them to keep a container of Tenebrio beetles (mealworms) in the classroom.
Here are two great sites about grasshoppers and other insects:

A few crickets are still chirping and crawling under leaves in my neighborhood but I rarely see grasshoppers. Time to create a small habitat so students can bring a cricket inside for a week!
