Lab instructions: Finding the right mix

By Mary Bigelow

Posted on 2010-03-23

I’m looking for information regarding student comprehension and/or performance when given basic, succinct instructions versus long, detailed lab instructions. I have heard convincing arguments for both, but I’d like to find out what the research says.
—Brandi, Oklahoma City, Oklahoma


Following directions is highly valued skill in many classes. I once heard a teacher say to a lab group whose results were different from the others, “You got the wrong answer because you didn’t follow my directions.” He missed a teachable moment to discuss how or why different results were obtained.
Your question implies that knowing how to design procedures for lab investigations also would be a skill worth developing. I’m not familiar with any formal research on the complexity of lab directions, so I’m hoping someone who knows of any will share the references. In the meantime, this sounds like an opportunity for your own action research in the classroom.
Action research is inquiry or research focused on efforts to improve student learning. Typically it is designed and conducted by teachers or teams of teachers who analyze the data from their own classrooms to improve their practice. Action research gives teachers opportunities to reflect on their teaching, explore and test new strategies, assess the effectiveness of the new strategies, and make decisions about which ones to use. Action research models generally have several components, which I’ve annotated with some thoughts:

Identify a focus area or research question. You already have a general idea (the effectiveness of lab directions) to reflect on. What do you want your students to learn from lab activities? What did you observe that prompted your question? A detailed set of directions (often called a “cookbook” lab) would seem to be foolproof: students who follow the directions would be more likely to get the “correct” results. How important is it for all students to get the same results and come to the same conclusions? What happens if they do not? Depending on the amount of directions, how would you expect the students’ thought processes to be different? Once students are familiar with a procedure or instrument, is it necessary to repeat the directions? What is the teacher’s role if the directions are not detailed? Do students think a long, detailed set of directions looks more rigorous and scientific?

Collect data. If you have more than one section, you could use detailed directions in one class and basic ones in another. You may need to try this with several activities. You’ll need to document the impact of providing different amounts of directions: the accuracy or consistency of data students collected during the activity, how students analyzed their results, the content and quality of the discussions between members of the lab group, and the procedures designed by the students. As the students proceed, listen to their conversations. Ask questions about their understanding of the purpose of the activity and how they decided on a procedure. Observe which students become frustrated with the minimal directions or which students display confidence and creativity. You could use photographs or videos to document the process. Examine what they are writing in their lab notebooks.
Analyze and interpret the data. Review the students’ procedures and their results using a rubric based on your vision of what a successful lab “looks like.” Look at the quality of their reports. Debrief them on their understanding of the procedures they designed and of the results. Discuss any frustrations or other feelings about the change in expectations.
Develop an action plan. Depending on your results and the experience level of your students, you may decide that some modeling and scaffolding will be necessary as they take on more responsibility for their work. Decide if it is acceptable for students to design the procedure as they go along or whether you want them to outline a procedure before they start the hands-on work. Consider if there are times when detailed directions would be appropriate (perhaps if you’re introducing a new lab technique or new instrumentation, if there are safety concerns, or if your students are novices at organizing data). If implementing your action plan leads to more questions, the action research cycle continues.
Action research is a systematic way to apply inquiry to your own teaching practices, and in many schools it is used as a professional development option. The results of action research are often published in the NSTA journals. You can examine these articles for ideas. I hope you will share your findings with us!

So how was the conference?

Skye Diers


“I appreciated the words that they (the leaders of Connecting With Animals in the Classroom workshop) gave us to convey how important animals with children, and animals in the classroom, and animals as an enrichment to a science curriculum—it’s really essential to have the real thing and not just models or pictures in it. I completely agree with them that kids are really interested in that, and you start from there, and then teach from their interest. And they’re interested in the real thing: They don’t really want a diagrammed picture of it; they really want to hold it, and pet it, and feed it, and observe it.” Skye Diers, Gingerbread Nursery School & Kindergarten, Oklahoma City, Oklahoma

Carl Ahlers


“It’s my third NSTA conference in the states. It’s worth every cent or any penny or any dollar I spent flying 24 hours to the NSTA conference…I meet all my supplies in the Exhibition Hall, and then apart from that, I get a once-a-year boost in my professional development…my sort-of new inspiration for the year here…One of the best guys out here—the most practical, hands-on guy—is Al Guenther, and that’s the biggest secret of the NSTA. Everybody should go to his lectures. He’s just so amazing [and a] magical presenter. I love to go to the evenings, the flashy science evenings, the chemistry, the physics shows…Each year, I think, ‘Maybe I’m not coming next year,’ [but] since I’ve discovered these conferences, there’s no way someone can hold me back.” Carl Ahlers, Melbourne, Australia

Tony Oyola


“The conference was great all around, and I’m learning a lot. I specifically went to [news correspondent and journalist] Garland Thompson’s [Shell Science] seminar because I’m reading his book, he’s inspirational in the book, and I wanted to get a firsthand experience on his inspiration, from his stories, from his books, and this is why I came to this conference…I picked up some freebies, concerning some free examples of books…so I can see what’s available out there for my K–8 school. I picked up some of those; they were very, very good.” Tony Oyola, Philadelphia, Pennsylvania

Vivian Ng


“I was really excited to sign up [for the conference] because I wanted more tools and techniques to teach science in the classroom. I’m getting certified in chemistry, and so I’ve been going to various chemistry workshops, but on top of that, I wanted to go to more general sessions as well to improve my teaching skills because I have very, very, very little experience in that, so I wanted to absorb different pieces from different sessions.” Vivian Ng, Preservice Teacher in Master’s of Science Education Program, Drexel University, Philadelphia, Pennsylvania

STEM ed … with whiz

By NSTA Web Director

Posted on 2010-03-23

Governor Edward G. Rendell of Pennsylvania addressed the “Science Matters” Town Hall Meeting in Philadelphia on Friday, March 19. In addition to describing the success of Pennsylvania’s STEM education programs and reeling off some facts and figures (e.g., Pennsylvania is the only state, according to Gov. Rendell, that has increased education spending during this recession), he listed the three things other places invariably get wrong when they try to make a Philly cheesesteak sandwich. You can watch his 25-minute talk on YouTube (that’s where the complete playlist is—below is part 1).

Appropriately enough, Gov. Rendell was sandwiched between two slices of panel discussion. The session was moderated by NSTA Executive Director Francis Eberle and included Dr. Cora Marrett, Acting Deputy Director, National Science Foundation; Dr. Christine Royce, Associate Professor of Education, Shippensburg University, and Executive Secretary of the Pennsylvania Science Teachers Association; and Carlos Contreras, US Education Director, Intel Corporation. These videos are also available for consumption on YouTube (part 1 below).

Children of science teachers helped demonstrate soil gradingThanks go to all the children who made it possible for their parents to attend the NSTA national conference by coming along with them! In addition to being a reminder of why we were there, these children often added to our experience by modeling activities in the presentations. This one even got his hands dirty helping Lisa Green (presenting with Candace Lutzow-Felling, Robin Coutts, and Emily M. Ford) classify a soil at the Outside the Classroom Walls: Creating a Backpack Lesson to Expand Student Learning session. The presenters are from the University of Virginia, State Arboretum of Virgina, Blandy Experimental Farm, and urged us to come see the backpack model in action.

Ideas sparkle at Intel Science Talent Search

By Lynn Petrinjak

Posted on 2010-03-22

NY Times columnist Thomas Friedman recently attended the 2010 Intel Science Talent Search Awards in Washington, DC. He listened to student presentations (including one which he freely admits was out of his scope) and talked with science teachers. He wrote:

In today’s wired world, the most important economic competition is no longer between countries or companies. The most important economic competition is actually between you and your own imagination. Because what your kids imagine, they can now act on farther, faster, cheaper than ever before—as individuals. Today, just about everything is becoming a commodity, except imagination, except the ability to spark new ideas.

More teacher talk

By Lynn Petrinjak

I didn’t get a chance to post on Saturday all the conversations with educators in Philadelphia, so I’m catching up a bit now.

“I had my 37th first day of school in August,” says Pamela O’Halloran, a middle school science teacher from  Tulsa, Oklahoma.  O’Halloran says she been attending  NSTA conferences “for years and years and years,” explaining, “It still reinforces what I’m doing, some of things I’m doing is the right thing, all the inquiry. But it also gives you a little spark.”
She wanted to share the NSTA experience with new teachers at her school; this year she is accompanied by three early-career teachers, including Natalie Smith”
“I teach eighth grade physical science. This is my first year teaching,” says Smith. “[O’Halloran] thought it would be a good idea for us to come and get some ideas and get some hands-on experience. You know, just kind of see what it’s all like and talk to some other people that are in the profession as well.
“See all of the resources. Get some ideas about equipment we might be able to purchase, or something, you know, that we can make,” Smith continues. “A lot of times, they just say, ‘You can go down to the hardware store. You can go to your local grocery store and you can pick up these ingredients or these chemicals or whatever.’ You can do something in the classroom with a very small budget if you need to. I’ve gotten a lot of good ideas so far.”

I also spoke with Sandy Krutchik of Flannigan High School in Pembroke Pines, Florida. She teaches anatomy and physiology primarily to  juniors and seniors. She was in the exhibit hall with some colleagues with a specific goal in mind. “We were looking for information on smart board technology…we were looking for ideas how to use [the boards] in the classroom,” she says. “We some ideas on how to incorporate ideas into the classroom.”
Teneka Coffey

Teneka Coffey, who teaches at Kipp Harmony Academy, a public charter school in Baltimore, Maryland, was attending her first NSTA conference. “I teach science to kindergartners. I came here because this is my first year teaching science,” she explains. “It just sounded like an exciting opportunity to connect with other science teachers and go to a lot of valuable workshops. My principal was supporting it and paid for the trip, so I’m here.”
She says her conference attendance will have an immediate effect on her classroom. “I went to several workshops yesterday. I received a lot of good materials, good ideas that I see I’m going to use, even on Monday with the unit that we were working on. One of those workshops I went to yesterday had a great activity that would go along with what we’re doing right now in the classroom,” Coffey notes. “It’s been very valuable. I’ve really enjoyed the exhibits and shopping and finding cool science stuff that I don’t find generally in the stores and around my area.”

I’m at the 30th Street Station (with free wireless), waiting for the train to go home. Philadelphia is a great place for a conference, and I enjoyed reconnecting with people and making new friends and colleagues. I have a list of new technology resources to try out, ideas for professional development, additional content knowledge, new thoughts to reflect on, and a few cool maps for my office wall.
Next year the conference heads to the West Coast. Mark your calendars for March 10–13, 2011, in San Francisco. California, here we come!

Sunday morning

By Mary Bigelow

Posted on 2010-03-21

Sunday morning is a tough time for a presenter. Early departures, church services, brunch dates, last minute sightseeing/souvenir gathering, or too much Saturday evening make it difficult for some to attend sessions at this time. But those die-hards who made it to the convention center this morning were treated to some excellent presentations.

Digital Cameras: An inexpensive tool for motivating, assessing, and enhancing instruction


Cameras in the classroom have come a long way from the Kodachrome days. Michael Kittel, Brian Gross, and Brian Heeney from Delcastle Technical High School in Wilmington DE shared some suggestions for teacher- and student-created photographs and videos: capturing teachable moments to review or debrief on, providing continuity between lessons, visually activating prior knowledge (and then re-activating after instruction), adding visuals to lab directions, illustrating misunderstandings, and showing examples of quality work. They walk around the classroom with their cameras to record those moments. They also showed the Eye-Fi wireless memory card that lets you upload photos instantly from your camera to your computer (no cables required). I know what I’ll suggest for my birthday next month!

Readers' Theatre in the Secondary Science Classroom


In working with elementary teachers, I was familiar with the Readers’ Theatre strategy to improve fluency and as a motivational tool. Students would take a role in a brief “play” and rehearse reading their parts (much like a radio play or a podcast). But Jill Purdy from Cedar Crest College in Allentown PA wondered how the strategy would help 9th graders who struggle with reading in science. She summarized her research on the topic, showing the positive results in fluency, comprehension of science topics, and attitudes. The small number of participants was conducive for a “seminar” setting. Lots of ideas to extend the practice were discussed: logistics in the classroom, using the strategy with ELL students, creating original “scripts,” and recording the performances as podcasts.

Wetlands Inquiry


So, you’re a presenter and your time slot is the last one of the conference. Will anyone come? Those who came to hear Judith Lucas-Odom from the Chester-Upland School District in PA were treated to a hands-on demonstration of how to help students make models to investigate watersheds, erosion, and point source and non-point source pollution. The activities are part of real-world investigations on water quality.
The presenter gave us directions for making a stream table with materials that can be found in discount stores. At first, I couldn’t visualize how the model would work (perhaps a lack of coffee was involved). But what made it real was actually creating the models ourselves. We found ourselves asking more questions: What would happen if…? Why did this happen? What does this represent? So the session ended with questions—perfect!

Sunday morning is a tough time for a presenter. Early departures, church services, brunch dates, last minute sightseeing/souvenir gathering, or too much Saturday evening make it difficult for some to attend sessions at this time.

view from my office at NSTA Headquarters


I’ll be heading home soon after a wonderful time in Philadelphia. The food here is awesome; I loved my “fancy-schmancy” hotel (Loews Philadelphia); and I bought nearly everything there was to buy in the gift shops, which I now will have to try to cram into my suitcase. It will be a physics lesson….
Most of all, I will miss my “up close and personal” chats with science teachers. Normally, I only get speak with you on the phone and e-mail you from my office in Arlington, Virginia (right; don’t you love those file folders!)

Have a safe trip home, and I hope to see you next year in San Francisco!

Amen!

Spend a little, gain a lot

Ted Koehn with his arsenal of inexpensive/free materials


Last year in New Orleans, I attended the session Sixty Labs You Can Do with Little or No Budget (see related posts below). Last year, so many people were there that some had to stand and some of us had to sit on the floor. I decided to go again this year because I was curious: Who would come this time? How many, given the late time slot of 5 p.m. on Saturday afternoon? What would I learn that I missed last time?
Ted literally describes his 60 high school physics and chemistry activities in a fast-paced, one-hour session. All of the materials he uses are either free or very inexpensive, and he even will tell you the exact amount–to the penny–he spent to acquire them (“at least in Lincoln,” Nebraska—his hometown—he adds). He provides each audience member with a packet containing guides for doing each of the labs, and the hour was filled with the sounds of pages turning as the teachers followed along.
He covered chemistry labs on moles, acids and bases, the periodic table, solubility curve… (the clock was ticking: 1 lab…10 labs…15 labs…)
…using gumdrops and toothpicks to create models of molecules…buying 100 chromatography strips for $3…10 vials of pH paper for $10…using eyedroppers as titration tubes…(20 labs…30 labs…)
Then came the physics labs. How to construct four inclined planes using inexpensive plywood…getting free ball bearings (from a truck repair shop) that students can roll down the inclined planes…checking garage sales for bargain supplies…propping a curtain rod on some books to create another inclined plane…(35 labs…40 labs)
…getting softballs from the PE department to use to teach projectile motion…”Ohaus gave out free spring balances in the Exhibition Hall; did you get one?”…having students use old film canisters and loading them with different amounts of pennies to see whether they would sink or float in water…(50 labs…60 labs! Hooray!) The audience applauded enthusiastically!

As you can see, the 5:00 start time did not deter science teachers from showing up for Sixty Labs. One teacher commented, “He’s amazing. I’m exhausted—but it was great!” (You can find Ted’s e-mail address online in the Saturday/Sunday program.)
Longtime readers of NSTA Reports, NSTA’s monthly newspaper, may recall the headline of this post was once the name of a popular column in the paper. (And hello to the former Reports editors reading the blog, who will remember the fun we had coming up with the names for the newspaper’s columns.)
