I have a few students who chatter excessively and need advice on methods that have worked to quiet the disruption. I also need to involve students who are reluctant to participate in a group setting.
—H., Arizona

I like a chatty, active classroom— provided the students are on task. I would give students opportunities to chat and work in groups but kept them focused on thought-provoking topics or problems. Organize the groups yourself to minimize off-topic socializing. Limit discussions to keep them moving forward and have follow-up or extension activities for those who finish quickly. Requiring groups to present overviews of their discussions can be a good way to wrangle the talkers and channel their discussion to the work.

When you don’t want students chatting, have assigned seats and be sure to separate friends who chat too much.

My advice for handling shy students changes with different types of group work.
Labs: Create roles that each member has to assume for hands on or lab activities. Here is a link to a resource in the Learning Center describing the responsibilities I assigned for science, technology, engineering, and mathematics (STEM) projects: https://goo.gl/EshMpi

Discussions/Workgroups: I believe shy students sometimes need more time to gather their thoughts and are less likely to join ongoing conversations. “Think-Pair-Share” approaches build in time for individual reflection and ensure that everyone in a group has a turn.

Employ some self-assessments or group assessments as part of the process. You are welcome to use these from my resource collection in The Learning Center:

Hope this helps!

When you have a moment to plan for teaching in January, reach for the 2018 November/December issue of Science and Children for inspiration. With a focus on visual literacy the activities discussed in the columns and articles promote helping children learn from and use images and models to understand science concepts. 

In The Early Years column, “Analyzing Media Representations of Animals,” I wrote up an activity using guidance from the National Association for Media Literacy Education (NAMLE) to analyze, evaluate, and create media. Many children’s books show images of animals that are not at life size, either to fit on the page or for convenience of design. If children have seen the animals they may be able to understand that the image is not at life-size, but if the animals are unknown, children can’t know what the actual size is. Engaging children in exploring how images accurately represent size or are possibly misleading, perhaps showing animals such as mice and horses at the same size, is part of teaching media literacy. Helping children create their own illustrations and photos of animals develops their understanding of how others use images.

What size is this animal in “real life”?

Can one of our senses fool another one? The Poetry of Science column, “Visual Poetry,” presents a poem, and science activity, and internet resources for additional support!

The Engineering Encounters column, “Bears on a Boat Plus,” is a visit into a second-grade classroom where we learn from science educators and English-language Learner specialists about their work revising the classic plasticine clay activity into a problem-based learning one. They used the 5E model (Bybee) for two one-hour lessons on consecutive days. (Karen Nemeth of Language Castle posted additional resources for “Working with an English Language Learner” on the NAEYC Hello social media site.)

Have your students ever drawn pictures of scientists or themselves as scientists? In the Methods & Strategies column, “Draw a Scientist,” Laura Beth Kelly offers suggestions for teachers who want to broaden their students’ ideas about science and scientists.

These four columns are only part of the helpful materials shared by educators in the 2018 November/December issue of  Science and Children.  Don’t miss reading pages 74, 75 and 80 where you can read the “Call for Papers” and be inspired to share your own science teaching practice!

Materials thoughtfully provided or set up by teachers often inspires children’s open exploration of a phenomenon. Much learning happens during this period of using their senses and tools to make observations of what intrigues them as they try things out, following up on their ideas and trying new things rather than making observations based on a teacher’s instruction. Specific activities and further focused exploration build from this beginning, as teachers hear or identify children’s questions, pose others, and additional materials may be provided. The Young Scientist series teacher resource books on nature, water, and building structures are a good starting point for developing science explorations.

In this class at the Clarendon Child Care Center, an open exploration of shadow using a wall and a lamp on the flloor opened up a stream of stories as children built on outdoor imaginative play where their shadows “ate each other.” Some of these marvelous stories expressed beginning scientific ideas about light and shadow. With a teacher nearby, the four and five year olds were careful with the light and had their stories recorded by teachers Sarah Abu-El-Hawa and Carly Gertler. Allowing the action to be child-led revealed their understanding of both the science of shadows and the structure of stories.

Further explorations were planned after asking questions such as, “How do shadows happen?” and “How do shadows come alive?” to help children reflect on their experiences. The class’s work continues. Documentation panels share the work with families and help children remember and think about their work thus far.

STEM Toys Promise to Turn Kids into Tech Geniuses. Grown-Up Coders are Skeptical

Like many parents, Dave Balter and Sarah Hodges spend hours and hours before the holidays each year puzzling over the array of educational toys that promise to help children develop scientific curiosity and technological skills. Toys aren’t just toys anymore. There’s a growing market for so-called STEM toys, which promise to imbue young minds with science, technology, engineering, and math skills. But for every product that helps kids learn, there are plenty of others that simply cash in on parents’ desire to prepare their kids for a changing economy. Read the article in the Boston Globe.

The ‘Dirty Secret’ About Educational Innovation

As part of the federal recovery effort to boost the economy after the 2008 recession, the U.S. Education Department suddenly had a big pot of money to give away to “innovations” in education. Since then, more than $1.5 billion has been spent on almost 200 ideas because Congress continued to appropriate funds even after the recession ended. Many of the grant projects involved technology, sometimes delivering lessons or material over the internet. In order to obtain the grants, recipients had to determine if their ideas were effective by tracking test scores. Results are in for the first wave of 67 programs, representing roughly $700 million of the innovation grants and it doesn’t look promising. Read the article featured in The Hechinger Report.

Project-Based Learning is a New Rage in Education. Never Mind That it’s a Century Old.

Put the phrase “project-based learning” into a search engine and the results could lead you to think that it is a highly successful approach to learning that is thoroughly modern and even transformative in a way never seen before in American public schools. While project-based learning can indeed be successful and exciting, it is hardly new. It is, in fact, a century old, as education historian Jack Schneider explains in this post.

Illinois Second Only to California in Number of Computer Science Degrees Awarded — and More from STEM Survey

Illinois is cranking out science and technology workers, but diversity and inclusion in the fields are still lacking. Illinois ranks fifth nationally in the number of STEM degrees awarded and has the fifth-largest STEM workforce in the country. Read the article featured in the Chicago Tribune.

Federal School Safety Panel, Parkland Commission Hit Similar Notes – Except on Guns

A school safety panel assembled by President Donald Trump took no stance on strapping teachers with firearms as a means to protect students in a report released Tuesday, taking a much softer tone than a Florida commission that recommended the measure last week.

To Fix the Tech Gender Gap, Fix Computer Science Education

This dearth of women in tech isn’t because women hate computer science or simply due to the widespread harassment that many women experience in the industry. The real reason men dominate the computer science industry is because computer science education is only accessible for a small percentage of students who are disproportionately male.

Putting the ‘E’ in STEM for the Littlest Learners

Watch 3-year-olds at play and you’ll see them building. On the beach, it’s a sandcastle encircled by a moat. In the classroom, it’s a towering edifice constructed of cardboard or blocks. Yet as natural as it comes to the youngest school goers, engineering hasn’t been incorporated into the preschool and kindergarten curricula the way it has in the upper grades. The “e” in STEM has been largely missing for the youngest learners, at least in any significant way. Read the article featured in Education Week.

Robotics, the Sport of STEM Education

A new sport is emerging in local middle schools — robot battles. St. Mary’s Episcopal School, a private all-girls pre-K through high school, held its first VEX IQ Challenge Tournament at its East Memphis campus last weekend. The event sold out within 30 minutes. If an indication is needed to show how popular robotics competitions have become among kids, that’s it. Read the article featured in the Daily Memphian.

All 50 States Plant a Flag for Universal STEM Education

Those of us who were terribly spoiled by the attention of prior federal administrations that championed science, technology, engineering and mathematics (STEM) education went to ground in January 2017. Although the March for Science in March 2017 was a clarion call for action, many feared that the national movement toward STEM literacy for all students was in mortal peril.

There are many safety hazards associated with the use of hand and power tools, and teachers and students should be trained to recognize them and understand what safety precautions should be taken to avoid them.

Safety Precautions

For hand tool use, follow these general precautions published by the Rose-Hulman Institute of Technology:

• Hand tools shall only be used for their intended purpose.
• Inspect tools for damage prior to use.
• Hand tools shall be maintained in good condition free of damage. For example, wooden handles on tools, such as a hammer or an axe, shall be tight and free from splinters or cracks.
• Bent screwdrivers or screwdrivers with chipped edges shall be replaced.
• Always direct tools such as knives, saw blades, etc. away from aisle areas and away from other employees working in close proximity.
• Knives and scissors must be sharp; dull tools can cause more hazards than sharp ones.
• Cracked saw blades must be removed from service.
• Wrenches must not be used when jaws are sprung to the point that slippage occurs.
• Impact tools such as drift pins, wedges, and chisels must be kept free of mushroomed heads.
• Iron or steel hand tools may produce sparks that can be an ignition source around flammable substances. Spark-resistant tools made of non-ferrous materials should be
used where flammable gases, highly volatile liquids, and other explosive substances are stored or used.
• Keep the work area and tools clean. Dirty, greasy tools and floor may cause accidents.
• Tools shall be stored in a dry secure location.
• Carry and store tools properly. All sharp tools shall be carried and stored with the sharp edge down. Do not carry sharp tools in a pocket.
• Wear the proper personal protective equipment (PPE).

OSHA provides the following general precautions for power tools use:

• Never carry a tool by the cord or hose.
• Never yank the cord or the hose to disconnect it from the receptacle.
• Keep cords and hoses away from heat, oil, and sharp edges.
• Disconnect tools when not using them, before servicing and cleaning them, and when changing accessories such as blades, bits, and cutters.
• Keep all people not involved with the work at a safe distance from the work area.
• Secure objects with clamps or a vise, freeing both hands to operate the tool.
• Avoid accidental starting. Do not hold fingers on the switch button while carrying a plugged-in tool.
• Maintain tools with care; keep them sharp and clean for best performance.
• Follow instructions in the user’s manual for lubricating and changing accessories.
• Be sure to keep good footing and maintain good balance when operating power tools.
• Wear proper apparel for the task. Loose clothing, ties, or jewelry can become caught in moving parts.
• Remove all damaged portable electric tools from use and tag them: “Do Not Use.”

Whether using hand or power tools, follow these five basic safety protocols to prevent accidents:

• Have regularly scheduled maintenance to keep tools in good operating condition.
• Use the correct tool for the job.
• Inspect all tools for damage prior to use. Never use a damaged tool!
• Read the manufacturers’ instructions before using any tool.
• By way of safety training, learn how to assess and use the appropriate engineering controls, operating procedures, and personal protective equipment.

Hand and Power Tool School Safety Programs

School administrations must develop a tool safety program that includes student and teacher safety procedures and employer and employee responsibilities for hand and power tools.

Suggested Employer (administrators and supervisors) Responsibilities

• Develop a hand and power tool safety program (including periodic evaluations and updates) based on OSHA and other regulatory agency standards.
• Provide oversight to make sure tools are free of defects and properly maintained.
• All tools must be operated according to manufacturer’s recommendations.
• Provide appropriate safety training and record keeping for employees using tools before working with them.
• Provide appropriate supervision to ensure employees and students are complying with the safety program.
• Make sure defective tools are taken out of service immediately.
• Conduct periodic inspections of instructional site using hand and power tools.

Suggested Employee (teachers and paraprofessionals) Responsibilities

• Attend safety training programs before using tools;
• Visual inspection for tool defects or hazards prior to use.
• Immediately tag defective tools as out of service.
• Report defects to supervisor.

For an example of a hand and power tool safety program check out the safety program developed by Rose-Hulman Institute of Technology. Also, check out this PowerPoint employee/student training program titled Power Tool Safety.
