Our department chair is encouraging us to add comments to student writing assignments. This sounds time-consuming; I have more than 100 students in my Earth science classes. Would students even read my comments on lab reports or term papers?
—Steve, Philadelphia, Pennsylvania
When students don’t understand the purpose of their assignments, they may think of them as something that happens so teachers can assign a grade at the end of a marking period. The type of feedback they get may reinforce this misconception. If all students see are red checkmarks, circles around misspelled words, and a “grade” at the top of the page, it is understandable when they put the paper into their notebooks without paying much attention.
Students may appreciate positive signs such as a generic smiley face or “Nice work” at the top of the paper. But it sounds like your department chair is focusing on informative feedback to help student recognize quality work and learn how to improve their writing.
Feedback should focus on what specifically the student did well, point out where the student may have made errors or demonstrated incomplete thinking, or discuss how the student could improve. With more than 100 students, it would indeed be overwhelming to write a detailed analysis for each student. Rubrics can be used to provide feedback, showing students how they performed on components of the task.
A personal remark or specific suggestions from the teacher can also be helpful to students. For each assignment, you could decide on a part of the task to focus on—the conclusion, the data tables, the graphs or diagrams, the description of the procedure, data analysis. Skim through the papers to get a general sense or patterns in the writing. Then focus your comments in this area.
Eventually, you’ll develop comments that can be personalized to various projects:
Should you provide feedback or comments on grammar and spelling? It’s common for rubrics to have an “effective communications” criterion that includes conventions, spelling, and legibility. But in looking at students’ writing in science, feedback on the content of the response and the use of inquiry skills should be more important considerations. You could spend hours trying to edit student work, highlighting and correcting every error in spelling, usage, or punctuation. But an overabundance of corrections could discourage students from writing. You could certainly ask students to revise for the basics of standard grammar and usage and correct spelling of words that are essential to the unit (those on the word wall or in their notebooks). But you will have to make exceptions for students who are learning English or who have disabilities affecting their writing.
Do students remember a teacher’s comments? I did not consider myself a writer in high school. I did what was expected on writing assignments, and my work was often returned with comments such as “Well done” on it. This generic comment did not do much to change my attitude about writing. In my senior math class, the teacher assigned a term paper (what was she thinking—a term paper in math?). I chose the topic of projective geometry and perspective, which I found fascinating. When I got the paper back, I looked at the grade, but what I remember most is Sister Raphael’s comment: “Your paper is so interesting, I put down my pencil and read it again for pure pleasure. Thank you.” That comment meant more to me than any “A” I ever received and changed my attitude about writing. If you’re wondering if your comments will have any effect, I still have the paper in my file cabinet more than 40 years later, and as a teacher I followed her example of providing feedback.

After reading the moving NPR story of a neurosurgeon who thanked his high school science teacher, investigative reporter Steve Silberman began to imagine all the other stories out there of a teacher’s influence on prominent writers, teachers, and scientists. “It struck me how rarely we hear from accomplished people about the debt they owe their teachers,” writes Silberman in the NeuroTribes blog on PLoS Blogs. Lucky for us, Silberman approached a number of scientists and writers and asked them “What’s the most important lesson you learned from a teacher?” Read the wonderful submissions he received from award-winning science journalists, best-selling authors, and researchers paying tribute to the teachers who influenced their paths. The stories are both entertaining and inspiring. As Silberman notes, “The words of a true teacher stay with us a long time, offering wise counsel in a confusing world and a potent inoculation against foolishness.” What’s the most important lesson you learned from a teacher?

My middle school students this year are very scatterbrained. It seems to take forever for them to get focused at the beginning of class and to find the materials they need when I ask for them during class. When it’s time to get into groups for a lab activity, there is a lot of commotion. Then they have lots of questions about what they’re supposed to be doing. Last year’s classes weren’t like this at all. What can I do?
—Margaret, North Carolina
It’s a common topic in the faculty room: “My classes last year were _____. This year they are so _____.” Teachers fill in the blanks with words such as cooperative, talkative, immature, energetic, needy, noisy, or inquisitive. It sounds like you would use disorganized to describe this year’s students.
For these students, you may need to establish routines to help them get and stay organized. Established routines free up time for more important topics and activities than dealing with logistical issues.
Visualize what a class activity should “look like.” In your mind, go through the activity in slow motion and focus on what the students should do to accomplish the task in an orderly and timely fashion. For example, you might establish routines for students to get their notebooks, access lab equipment, or enter/leave the room. Here are some routines that worked for me.
The beginning of a class period can be hectic as one group leaves, another enters, and the teacher takes attendance and performs other duties. Try posting an “agenda” that students see as they come in. Set aside a section of the board or project the agenda onto the interactive board. The agenda could include the purpose or big idea of the lesson, the activities for the class period, assignments they should have ready for you to check or turn in, and what they need to have ready at their seats (laptop, notebook, paper, pencil, textbook, etc.).
It may take a few days for students to get used to the routine of reading the agenda and getting things ready at their seats. I found that combining the agenda with a brief warm-up activity helped students focus for the rest of the period.
Rather than students selecting different teammates for each activity, use the same lab groups for a while. Assign students to groups, with a promise that you’ll change them in the future. Designate a space for each team to work on lab activities. Appoint one student in each group as the “coordinator” whose job is to get the materials for the activity. He or she should be the only one from the group who needs to move around the room. But you can minimize that movement by having all of the materials for each group in a box or tray. Designate another student in each group to be the “liaison.” This student is the group’s spokesperson and is allowed to ask you questions about the activity on the group’s behalf.
Routines at the end of the class period can help students organize their thinking before going on to the next class. For example, ask the students to complete a brief exit activity before departing. This can be a written summary in their notebooks about the day’s activities, thoughts about an upcoming lesson, or a reminder of due dates for tests, projects, or other assignments.
When students are learning your routines, you’ll need to demonstrate and model them and provide opportunities for practice. Since the school year has already started, it may take a while for students to catch on to them, but the effort is worth it.

Treating the economy with STEM students
By Shiv Gaglani
I began doing medical research as a freshman. Not in college; in high school. I had the good fortune of being able to find a professional scientist who was willing to take a chance by giving a 14-year old the opportunity to excel and innovate. The excitement of discovery kept me going both in the lab (in spite of the high experiment-failure rate) as well as in the classroom (learning about the digestive enzyme trypsin is more interesting when you have held a vial of it). Research not only taught me about the specific topics I was working on, such as the biology of stem cells, but also helped me develop confidence, perseverance, creativity, and the ability to simplify and present ideas through analogy:
Imagine for a moment that our economy is a human body. Like the body, the economy is made up of countless workers (cells) that compose many essential interdependent systems. The skin, for example, is analogous to the national defense system; the circulatory system corresponds to the transportation sector; the liver to the healthcare system; the bones to infrastructure; and the heart to the energy sector.
The financial sector—Wall Street, the Treasury and the Fed—is the brain behind the economy and, as recent experiences have proven, like its physiological counterpart it too is highly vulnerable to damage resulting from poor decisions. Also of note is the division between controllable and autonomous brain functions, though, lamentably unlike that of the human body, the economy’s involuntary behavior does not always tend towards self-preservation.
As important as each of these systems is, the definitive element responsible for the size and strength of the body is the muscular system; in the case of the economy, this is the science and technology sector. Muscles are the driving force of the body, just as scientific progress and technological innovation are the driving forces of our economy. In fact, though scientists and engineers only comprise four percent of the U.S. workforce their discoveries and inventions add a disproportionate number of jobs for the rest of us. Case in point: two part-time engineers named Orville and Wilbur effectively began the airline industry that now employs about 11 million people and contributes over $700 billion to our GDP.
The crisis now is that our innovative science and technology muscles are increasingly dystrophic, especially in comparison to those of other economies like China’s and India’s. Our colleges graduate more visual and performing arts majors than engineers and, of the engineering Ph.D. students we graduate, over 70 percent are foreign-born. These students are increasingly choosing or being forced to return to their home countries, often due to their inability to renew their visas or obtain green cards. It is no surprise, then, that over half of all patents awarded in the U.S. are now filed by foreign companies. There are countless other indicators foreboding the loss of American dominance in scientific and technological innovation, prompting the critical question: how can we treat this problem?
One of the most promising emergent therapies for treating damaged or diseased body systems is stem cell technology. Stem cells are unique due to their potential to become many different types of adult cells—skin, bone, liver, brain, muscle, etc.—and ability to renew and replace senescent or atrophying tissue. Hence, our economy’s stem cells would be our students, since they have the capability of pursuing any profession through which they may contribute to the vitality of the entire economic system.
In the same way that the human body relies upon stem cells for its health, our economy desperately needs STEM students (Science, Technology, Engineering, and Mathematics) in order to strengthen and grow. However, the key difference between stem cells and students is that the former choose their fate according to the needs of the entire system, whereas the latter choose their profession in part based upon cultural desires and influences such as reputation, fame, and fortune – all of which can more easily be found on the field or stage than in the lab. As researchers search for ways to increase the number of stem cells and influence their differentiation in order to deliver medical treatments, so should our nation focus on improving the desire among young people to pursue and excel in STEM disciplines.
The Obama Administration’s Educate to Innovate initiative as well as the President’s discourse about our Sputnik Moment and the need to celebrate science fair winners on par with Super Bowl winners are great first steps towards producing and inspiring STEM students. Similarly, the support of major companies like Intel, Google, and Siemens is critical to providing students scholarships and recognition for their inventiveness and initiative. However, it will be as important for the media to celebrate the scientific and technological drivers of our economy at least in equal terms as they cover the entertainers, athletes, and politicians on our television screens.
My early exposure to research set me on the committed path of scientific innovation, and it is my hope that, through the above-mentioned policies and encouragement from fellow students, my younger peers may develop a similar passion for STEM. I believe this will be the most effective treatment for healing our economy in the long-term.

What is in motion in your classroom, in addition to children? Spinning tops are one of the materials I keep available all year long because they can be an independent or collaborative activity, children’s ability to spin them increases as they grow, and spinning tops is an exploration in physical science. The October 2011 Science and Children is all about motion—read to learn more about teaching children about pushes and pulls.
Spinning tops can be part of learning mathematics. Young children can sort tops by size, weight, and shape, then record which top needs the biggest twist-push to begin spinning, and which top spins the longest. The concept of symmetry can be introduced. Children can observe the wobbly motion of a top made purposefully off-balance by the addition of a sticker on one edge or a crown (center post) placed off-center but measuring tiny differences in weight-distribution which affect how well a top can balance is too difficult. After several weeks of child-initiated play with tops, a few four-year-old children were able to predict that a top with a post placed purposefully off-center would not be able to spin. Younger children could not make a prediction or guess and had to try spinning the top. They lost interest when it “didn’t work” and did not investigate it further.
When a top “doesn’t work,” young children may not investigate possible causes such as slowed spinning due to an uneven surface, a loose crown (center post) making the top off balance, or too little strength in the child’s spin. Keep a variety of tops available and support children, before they walk away, with direct instruction on how to grip and turn the top’s crown to make it spin.
Conversations and group discussion can help children build an understanding of the motion of an object. I have children draw the motion of an object (rather than the object itself) and we use the drawing to talk about the push or pull needed to get the object moving and to make it stop.
Older children may be interested in making their own tops using stiff paper and sticks, short pencils, straws, or sections cut from wooden chopsticks. Children will probably need help with the task of balancing the top by making sure the post is in the exact center and the body is a precise circle.
The Spinning Top & Yo-Yo Museum invites you and your class or other group to be part of International Top Spinning Day on Wednesday, October 12, 2011, by spinning a top anytime and anywhere. You can let the world know how many participated by reporting your spins on the museum website. Last year there were more than 20,000 spins!
Spinning motion can be explored outside on spinning playground equipment. In this setting the children can feel the motion and pulls and pushes as they spin around.
Provide drawing materials as children explore and document the motion of themselves and other objects—swings, wheels on toy cars, slinkys, hula-hoops, and balls in bowls.
The Spinning Top & Yo-Yo Museum notes that tops are known all around the world:
Argentina Trompo, Australia Kiolap, Bulgaria Pumpal, Cambodia Too loo, Denmark Snurretop, Ghana Ate, Greece Sbora, Iceland
Skopparahringla, India Lattoo, Japan Koma, Korea Pang-lh, Mexico Trompo or
Pirinola, New Zealand Potakas, Puerto Rico Chobita, Russia Volchok, Sri Lanka
Pamper, Switzerland Spielbreisel or Pfurri, Taiwan Gan Leh, Turkey Topac, United
States Top, and Venezuela Trompo or Zaranda
What name do you call these toys that teach science concepts?
