Perhaps the greatest roll in technology for science education is helping students find their passions in science. As both men point out, fantastic things happen when passions ignite.

From social interactions to simulations to blogs, there are so many elements that can contribute to this and help students to have multiple experiences with multiple voices.

Of course, passion can also come from looking forward to a career in science and getting paid for the work they will do. Speaking of which, there are now blog sites that can link you with an advertiser to get paid for your passion, such as Link From Blog. It is great to connect passion with future earnings, but Jim Gee really makes the point, that it is not always necessary.

Science teachers should have a template that they use in their day-to-day lessons. A template reduces the need to re-type information on a daily basis, and a template is a reminder of important areas for the teacher to include.

I have been using a Microsoft Word template for about seven years now in my preservice teacher classes. Overtime, I have modified the template, adding sections and deleting others. On a recent assignment in my elementary science methods class, I had a lot of strong lesson plans submitted by my students. Paige Hogg wrote an excellent Parachutes, and I am attaching her lesson plan as an example of a strong lesson and the use of a lesson plan template.

(1) STANDARDS: SUPPORT THE CURRENT STATE-LED MOVEMENT FOR SHARED STANDARDS IN MATH AND SCIENCE

(2) TEACHERS: RECRUIT AND TRAIN 100,000 GREAT STEM TEACHERS OVER THE NEXT DECADE WHO ARE ABLE TO PREPARE AND INSPIRE STUDENTS

(3) TEACHERS: RECOGNIZE AND REWARD THE TOP 5 PERCENT OF THE NATION’S STEM TEACHERS, BY CREATING A STEM MASTER TEACHERS CORPS

(4) EDUCATIONAL TECHNOLOGY: USE TECHNOLOGY TO DRIVE INNOVATION, BY CREATING AN ADVANCED RESEARCH PROJECTS AGENCY FOR EDUCATION

(5) STUDENTS: CREATE OPPORTUNITIES FOR INSPIRATION THROUGH INDIVIDUAL AND GROUP EXPERIENCES OUTSIDE THE CLASSROOM

(6) SCHOOLS: CREATE 1,000 NEW STEM-FOCUSED SCHOOLS OVER THE NEXT DECADE

(7) ENSURE STRONG AND STRATEGIC NATIONAL LEADERSHIP

The report begins with this summary of the importance of STEM:

The success of the United States in the 21 century – its wealth and welfare – will depend on the ideas and skills of its population. These have always been the Nation’s most important assets. As the world small measure by the effectiveness of science, technology, engineering, and mathematics (STEM) education in the United States. STEM education will determine whether the United States will remain a leader among nations and whether we will be able to solve immense challenges in such areas as energy, health, environmental protection, and national security. It will help produce the capable and flexible workforce needed to compete in a global marketplace. It will ensure our society continues to make fundamental discoveries and to advance our understanding of ourselves, our planet, and the universe. It will generate the scientists, technologists, engineers, and mathematicians who will create the new ideas, new products, and entirely new industries of the 21st century. It will provide the technical skills and quantitative literacy needed for individuals to earn livable wages and make better decisions for themselves, their families, and their communities. And it will strengthen our democracy by preparing all citizens to make informed choices in an increasingly technological world.

Chapter 5 focuses on teachers and begins with this statement:

Anyone who has set foot in a classroom knows that teachers make a huge difference in the lives of their students. While not everyone can recall the influence of a legendary teacher like Jaime Escalante, many people have stories about the crucial role that a teacher played in sparking their passion for a subject, teaching them a lifelong skill, or helping them surmount an obstacle. Indeed, most people who work in STEM fields or who simply have an interest in STEM can point to teachers who excited about them about the beauty and power of mathematics, the wonders of science, or the power of technology – and who helped them learn that they could gain mastery of these subjects. Sadly, though, many adults also point to experiences in school that convinced them that STEM subjects were inherently boring, cryptic, or beyond their grasp.

The report correctly points to the importance of STEM for our nation, and suggests compelling steps to improve what we do.

This week I was at Santa Clara Unified School District visiting Kathie Kanavel,  Coordinator for Educational Technology. Kathie told me about her math teachers using their Lumens document cameras to record their lessons, with audio, and then they post them to YouTube. What a great way for students to review the lessons. Parents who are trying to help can also experience the lesson.

Adaptive Curriculum has a different way of engaging students in a lesson on surface-area to volume ratio. They use the discrepant event of cheese cubes in a microwave. Most of us, because of conventional oven experiences, would think that the smaller cubes would melt first. But with a microwave oven, the cheese heats from the inside and the larger cube, because it has a smaller surface-area to volume ratio, retains heat better and it melts first.

Most kids aren’t going to rejoice in this news. They are holding out for the research that says that it helps them to do homework if they are also watching TV. I guess if there are parents who make their children go to some solitary confinement place to do homework, the children might be happy to see this news. My sons seem to enjoy doing their work in the kitchen/family room area, where we tend to congregate, and my wife or I are available to help. They do have a built in desk/office space that has no windows and is cluttered. I was thinking about clearing some clutter so they would actually use their desk area, but now I can point to this 1978 study as evidence that their desk area is perfect. To be honest, I don’t really mind where they do homework and study, just as long as they do it.

Extending this idea, the varied environments created through virtual learning are better than “different rooms.” Students can learn while on Mars or learn while at the bottom of the ocean. Just consider some of the over four hundred Activity Objects of Adaptive Curriculum, students find themselves as mechanics in a car garage, on planets from different solar systems, in Egypt studying mutualism, in a chemistry lab, in a music salon, controlling a reactor in a nuclear submarine, at an amusement park constructing a roller coaster, living in Europe 500 years ago, and producing a theatrical production. Clearly my house doesn’t have rooms that are this interesting, my advertisement might be, “you can wash dishes in the kitchen.” Actually, we do make an effort to have an interesting home environment with interesting décor from different places around the world where we lived, a pool, a trampoline, a basketball court, a lawn, two fish tanks, a reptile tank, two sulcatta baby tortoises, one shelty, and an exercise area. My home, just like most other homes, is more interesting than the typical classroom. The beauty of virtual science activities is that we can take students out of the classroom. I don’t mind an occasional replication of a classroom lab, but the true power of virtual learning is taking students outside the walls of the classroom.

I hinted at controversy in my opening sentence. The Times article also called the whole notion of learning styles a myth; A dangerous statement with so many teachers eating up the invented multiple intelligences of Howard Gardner. I predict in 2020, Gardner will state that there is an intelligence for creating new multiple intelligences. While it is clear that some people are better at some things than other people are, at what point do skills, abilities, and knowledge become grouped as intelligence? I think I should rush to invent “soccer intelligence,” “volleyball setting intelligence,” and “interior design intelligence.”

The great regard for Gardner’s work by teachers is no doubt because teachers see different learning styles. Any teacher who has taught for several years will know that students have varied learning styles. Come on, how obvious, some students learn quite well by reading a textbook and others simply don’t. If you have ever been in school and there was a subject that didn’t come naturally to you but did come naturally to others, you would also realize this. So, I’m not sure how you can state that, “The contrast between the enormous popularity of the learning-styles approach within education and the lack of credible evidence for its utility is, in our opinion, striking and disturbing.”

Color Mixing at a Theater: Paints and Lights

To be sure, a teacher with only a dry-erase marker and a class of 35 adolescent students might have a difficult time adjusting to the learning styles of students, so we might expect little “utility” as he lectures. But if given the training, resources, and a suitable class size, teachers can know their students better, and plan a variety of experiences to help students learn science. One powerful tool for helping students learn at their own pace, and in ways they enjoy, is internet-based science experiences.

When I was doing my sabbatical at the University of San Carlos (Cebu, Philippines), Ed Van den

Berg (one of the really great guys in science education), would have the undergraduate secondary education science students put on physics and chemistry demonstrations for the local school children. It was a delightful way to give them experience teaching and expose children to the interesting world of science. In the picture, two of my students demonstrate their fire tornado. (See http://www.west.asu.edu/rillero/philippines.htm for more of my photographs from the Philippines.)

In this YouTube video below, a similar program is described called “The Little Shop of Physics.”

We all want to avoid having children get hurt doing school science. We also don’t want teachers to avoid doing hands-on science because of fears related to safety issues in the science classroom. For the elementary school classroom there are a couple of valuable resources that can help teachers and administrators develop safer practices for science instruction.

These are:

Science and Safety: It’s Elementary (http://www.csss-science.org/downloads/scisaf_cal.pdf)

And

Safety in the Elementary (K-6) Science Classroom (http://membership.acs.org/c/ccs/pubs/K-6_art_2.pdf)

Many of these practices have been written with common sense in mind. And if you are safety minded, you are on the lookout for all the potential things that can go wrong and ways to prevent these accidents. Unfortunately, K-5 classrooms would not have some of this safety equipment, such as eyewash fountains, fume hoods, and safety showers, and probably most middle school science classrooms would come up short in these areas.

While going all virtual to avoid safety problems may be tempting, a more pragmatic solution is to avoid dangerous hands-on materials and be very careful to try science activities before hand, and monitor student behavior.

Technology For K-6 Science Safety

While technology is often thought of as electronic stuff, a better and wider view is that it is any human made products that make our lives better or safer. With this in mind, I present my top ten safety technologies.

1. Teacher Developed Safety Rules Contract: A teacher and students who are safety minded is probably the best defense against accidents. There should be no toleration of inappropriate behavior when doing hands-on science.

2. Goggles: Chemical splash safety goggles should be worn whenever what you are working with has the potential to hurt or damage eyes. Please don’t adopt the view, such as, “I use ammonia at home without goggles, so it is okay to use it in school without goggles.” An adult can decide not to use goggles at home and it is at their peril. If a teacher decides not to have students wear goggles with materials that could harm eyes, and eyes are damaged, the teacher will probably be held culpable, as will the administrators, the school, and the district.

3. Disposable Nitrile Gloves: From dissections to handling chemicals, these can prevent problems. And if a student is bleeding for any reason, an adult should put on gloves to help with the situation.

4. Locked Chemical Cabinet

5. Fire blanket and extinguisher

6. First aid kit

7. Proper waste containers

8. Rubber covered muslin aprons

9. Safety posters and signs

10. Non-mercury thermometers

Teachers should be urged to provide hands-on experiences for their students. But teachers are also responsible for the safety of their students.

With a partner, my secondary science methods students selected a tree and then combined their ample knowledge, creativity, and critical thinking and came up with several methods to determine the height of the tree.

Linda Dee and Karen Schedler were helping my students learn about Project Learning Tree (PLT) and its many science activities. My students now have the assignment to develop a lesson plan using a PLT activity and then teach a high school or middle school class using this lesson plan.

This class of students has already earned my respect for their knowledge, abilities, and great attitudes, but it was still exciting to see them apply what they know with their creativity and critical thinking. Indeed the process was just as important as the result. Their tree-height-measurement methods included (a) having a partner of known height stand by the tree and estimating how many of them it would take to reach the top of the tree; (b) measuring the shadow length of the partner and the tree and using ratios; (c) holding a vertical ruler up, with the partner at the tree, and using the marking of the ruler to determine ratios for the heights, and (d) comparing the tree height to a building and then counting brick segments on the building to determine height. Of course, if a protractor was on hand we could have used the distance from the tree, angle to the top of the tree, and some trigonometry to make this estimate.

The tree height estimates were compared to a value found by using clinometers. These nifty devices, we were told, give a pretty accurate reading. You measure off 66 feet and look through the viewer with one eye and line up a horizontal line with the other eye. There were two scales for viewing the height of the tree, one in feet and the other in meters.  In many cases, my students’ estimates were pretty close to the clinometers’ readings.

I was glad to see my students using metric measurements because we had talked about this before our spring break. My advice is to have their future students do all their measurements using the metric system and NEVER convert back into the imperial system. But with the “66 feet” distance and foot scale on the clinometer, it seems like our forestry colleagues, at least in the US, are not fully metrified. Prior to this, I had thought that the only people of science who were not completely immersed in the metric system were US meteorologists. It is obvious that some science traditions don’t change easily.
