Framing critical thinking and practical skills

Framing_600px_1116

Sometimes, we forget how much we know. The way our education system works, we build upon our knowledge from year to year and increase our skills and abilities as we grow. Those basic counting skills from kindergarten help us learn addition and subtraction. Then we move on to multiplication and division. From there, we enter the realm of fractions and decimals and even . . . unit conversions!

One of the rewards of teaching is seeing the light come on for students. It’s exciting to see students recognize that one skill can create a new related skill. When they recognize how much they know, it increases their confidence in other areas. All that knowledge and skill development needs to be reinforced with application. There are many ways to do this.

Framing kits are a way to synthesize a lot of knowledge into a practical application. In other words, framing kits can help students recognize how much they know.

My son has an amazing gifted teacher, Mr. Bradley Johnson, who knows how to turn knowledge into application. Last year, my son was struggling with math being relevant, so Mr. Johnson challenged him to put his drawing skills and interests to use.

HouseFramingKit_350px_1116The assignment was to build a model house. The process included making a scaled drawing, working out unit conversions, and building the model. Math became very relevant, but something else happened too. Watching my son wrestle with how to take his drawing and make a model was like watching a movie about critical thinking. His critical thinking improved significantly the further into the project he got.

In the end, he opted to use dimensioned lumber to make his final model. When the project was completed, I asked him why he didn’t use a framing kit. “You mean there was a kit?” was the reply.

Framing kits, at the most basic level, are dimensioned lumber with instructions. At a different level, framing kits are a way to synthesize a lot of knowledge into a practical application. In other words, framing kits can help students recognize how much they know. Not only do students practice creating an architectural model, they apply practical math, blueprint reading, construction, instruction following, vocabulary building, and critical-thinking skills.

Students who’ve created blueprints or drawings, like my son, can use dimensioned lumber to construct a model for demonstrations.

If the student hasn’t created a drawing, a kit with all the materials required to construct a frame might be more useful. Students will measure, mark, and cut the dimensioned lumber to the proper length and angle. Then the fun challenge of assembly can begin.

Framing kits can be general, such as the Hearlihy Wood Framing Kit or specific like the A-frame Cabin Kit 101. No matter which kit you pick, the intrinsic reward of building something and seeing the finished product can’t be replaced.

Remind your students of what they know. Explore adding framing kits, model houses, or dimensioned lumber to an activity in your lesson plans. It might spark some creative thinking and frame some practical skills.

Have you visited the Drafting 101 section on Hearlihy’s website recently? If not, you might have missed that video content is now there.

Ray Grissom and Alan Kirby discuss 3-D printing troubleshooting.

Ray Grissom and Alan Kirby discuss 3-D printing troubleshooting.

First, we’ve added a video focused on 3-D printing troubleshooting tips. We filmed our own Alan Kirby and Ray Grissom, both highly experienced with 3-D printing, and they discussed some of the history of 3-D printing and then dove into the key problems that can affect your printer’s ability to work properly, including the following:

  • Calibration
  • Clogging
  • First layer not sticking to base
  • Warping
  • The difference between open and enclosed printers

Second, we’ve added a couple videos with Merrick Russell, teacher and developer of the 3-D Perspective Drawing Boards that Hearlihy offers. In the first video, he explains the advantage of using the boards and how they make perspective drawing – traditionally a more difficult skill – accessible to different levels of drafters.

HCO video post imageCommunicating ideas is the key function of technical drawing and drafting, according to Russell, and these drawing boards help students express their ideas quicker, whether they are in a drafting class, construction class, or whatever creative class uses perspective drawing. Merrick says the tool enables students to realize that they can design and create things that they have in their minds.

“They can actually draw those ideas and start to explain themselves graphically,” Merrick said. “I like to think of the product as more than just a drawing board or another drafting product. It’s a creativity tool – and that kind of makes all the difference.”

In the second video, he shows the ease of creating drawings using the boards. Visit the Drafting 101 section to take a look at these videos and other resources.

Designing tips for screen printing

Silk screen printing screens stored in a wooden rack ready for p

Screen printing isn’t limited to only T-shirts. Clothing items are the most obvious choice, but the process works well for tote or lunch bags, mousepads, vinyl binders, clock faces, decals, balloons, tiles, flags, and signs too. Some of these items require different types of inks, preparation, and drying techniques, but the same basic design considerations have to be used.

Unlike printers that can lay down several colors in a precise dot sequence to create full-color images, screen printing is a stencil method that uses one screen per color and lays down one color at a time, usually starting with the lightest color to allow for overlapping.

The first thing to consider when you start a screen printing project is what colors of ink you plan to use. It’s helpful to plan the color of the substrate at the same time.

By mocking up these combinations on-screen, you’ll be able to make sure you have your desired contrast and the colors work well together. Keep in mind that if one of the design’s colors is the same as your T-shirt, you can use it as negative space and save on an ink color.

ScreenPrinting3_0816After the colors are chosen, then add all of them to the color swatches panel in the software you’re using to design your image. These can be either RGB or Pantone (PMS) colors. Keep in mind that PMS colors can vary from screen to screen, so rely on your printed Pantone guide for the expected outcome on your substrate and be sure to use the Solid Coated Formula Guide. If using RGB, you’re relying on the your screen colors to choose the closest available PMS color based on what you see. This can be affected by the brand of the screen, the computer display setting, and ambient lighting.

A vector format, such as EPS or AI, that uses math instead of pixels to draw shapes, lines, and curves is preferred when designing for screen printing. Illustrator is a favorite software of designers and allows for resizing without sacrificing quality. A vector format is generally also smaller in file size and isn’t flattened, so it’s highly editable.

When you’re ready to work on your design, change the background color to match your substrate and create a separate layer for each color. This will enable you to turn the colors on and off, which gives you a visual of how each ink color works individually.

If you’re working with text, I recommend that you leave the working text box on the pasteboard. Then, copy and paste it on to your artboard and create outlines. If you’re sharing your file with anyone, this eliminates the need to worry about fonts. You never know where you’ll end up with a design, and sometimes it’s necessary to start over with an element. Trying to remember what font you used and any other formatting you started with can be time consuming and frustrating.

Another consideration is the size of the lines in your design, and it strongly relies on the size of mesh being used to screen print. Generally, a 0.5pt line is too small, and 1pt still might not be big enough. If you don’t know the size of mesh being worked with, then, to be safe, you might need to use 2pt lines. Also, if you’re using your design for several types of printing, be aware of how resizing is affecting your lines and what your preference setting are. There is a Scale Strokes & Effects option in Illustrator under General.

Don’t forget that just by creating a design in Illustrator, you’re not guaranteeing a vector image. To do so, you must save using the proper file format. Vector formats include AI, EPS, and PDF.

These are just a few tips to get you started designing for screen printing. No two screen printing setups are identical, so be sure to understand the resources you have available and what limitations they have before you start designing.

Stuffed spaces – classroom storage ideas

Classrooms seem to constantly need more storage. Whether it’s finding space to store pop bottles for AP rockets, wood blocks for CO2 cars, or screens and ink for screen printing, you often have to be creative and take advantage of the smallest spaces. Schools like to use what they have and make things fit when they can.

To take an existing old or generic product, and making my own modifications to meet my classroom needs was common during my teaching days. Don’t get me wrong – I had adequate scope and breadth for what I was teaching, but using a flat filing storage cabinet to store light-sensitive offset plates made me nervous on more than one occasion. This method for storage worked as long as students followed the procedures they were taught, however occasionally a drawer would be left open and light-sensitive materials would become damaged.

Later in my career, when I began teaching drafting, I appreciated having the flat file storage to better manage student projects, and the use was more in line for its design. Although teachers are known for their creativity, getting boxes from the schools’ food service or copy room is practical for only so long, and those resources can become limited depending on the number of other staff looking for alternate storage. So what is a teacher to do?

First, purge.

I was a teacher who kept everything that could possibly have a use. Looking back, that might not have been the best use of my space or time. I had boxes of curriculum that went back more than a decade and were used by several teachers prior to me. Was they ever going to be used again? The short answer was no, but then I might have that one student whom I could use it to connect with.

Teaching Graphic Arts and using a large-format printer, I needed a way to keep track of different types of roll paper, and I found a wire bin roll file useful for keeping things in order. In the end, I had all the resources in current material to meet my students’ needs, especially with the changes in technology happening as rapidly as they do.

Look at what you’re going to need for storage in the next year to hold the supplies for planned activities. Plan ahead and be sure to leave space for those activities you will hear about for the first time in the coming months. Then plan for about ten percent more if you can.

You’ll also need to plan for any records you might need to keep on students based on your school and state needs. Vocational and Technology teachers in my state, while I was teaching, needed to keep grade documentation and competency profiles for several years past a student’s graduation date. That takes storage space.

Filing cabinets are a great resource, and come in more than the standard two, four, or five drawer vertical file. Consider a lateral file for similar storage in a more convenient place to access space and make an attractive addition to your classroom. Another option for keeping student supplies is to use a storage cart for the current project or for individual student temporary storage. These come in three-, six-, 10-, or 15-drawer configurations to meet your specific application.

If money is a problem (and in the school setting, where isn’t it!) there are usually students in the wood shop or cabinet making program that need a project to do. This might be ideal from a space perspective, as you can design and have the space custom built to your needs. The downfall is you might be waiting for a student to have time to do the project, or you might need to finish it yourself if the school year is over before the project is complete.

Storage is a never-ending problem. Ultimately, you’ll need to be creative where and how you manage your storage space.

Simplifying 3-D to 2-D with the Ortho-Box™

OrthoBox_0716

Visualization takes practice. Being able to picture all the angles of an object without it right in front of you is no easy task. Luckily, Hearlihy has you covered with the Ortho-Box™.

An orthographic view is a representation of a three-dimensional object in two dimensions. This is what the name for the Ortho-Box originates from.

The Ortho-Box is a simple way for students to improve their spatial reasoning and 3-D picturing skills. To use the Ortho-Box, place an object inside and use overhead projector markers to draw what you see on the clear, acrylic sides of the box from the front, top, and right. You can use the included wooden shapes as your object or any other object you happen to have. After finishing the drawing, open the box and look at the top and side panels to see an orthographic view of the object inside.

The Ortho-Box gives students a hands-on approach to grasp the basics of an object in the physical world before moving on to the digital world. Doing a few drawings of different objects provides students a solid foundation leading into the next step of using 3-D computerized projection. The Ortho-Box is a hands-on project that all drafting and engineering students can benefit from.

Metalwork steels skills

Metalworking_0716

Metalworking3_0716There are a lot of processes that lend themselves easily to a classroom. Some processes require specific equipment to perform tasks. Other processes take very little tooling to do the work.

Traditionally, metalworking is a field that requires specific equipment, but there might be a way to incorporate some small-scale metalworking processes into your classroom, even if you have limited tools to work with.

Shops that have the metalworking tools in them today might include a punch/shear machine, a rivet/bend/roll machine, and scroll formers to do the basic operations. Others might have English wheels and planishing hammers for smoothing and forming sheet metal into shapes other than bends and seams.

Basic operations that students need to know to be Metalworking2_0716successful in metalworking include riveting, bending, rolling, punching, shearing, scrolling, and twisting. Metal can also be formed through casting, heat treating, or forming. Seldom does the raw material take final form after one process. Even a simple hammer, as it’s manufactured, goes through several dies as it’s drop forged, trimmed, given the final finish, and then receives the handle.

A hip roof toolbox has been the project of many industrial arts students over the years, and with good reason. The student uses their knowledge of measuring distance and angles to create a three-dimensional object from a flat sheet of metal. The base is a rectangular cube that includes folding, bending, seaming, and riveting the sides together with the bottom with mostly 90-degree angles. The top of the toolbox teaches students how to cut, bend, fold, seam, and rivet with varying angles. Attaching handles and a top put the finishing touches on some projects; others include building a tray of either sheet metal or wood to make the toolbox more versatile.

As you plan your classroom for next year, consider how the addition of some small metalworking tools can teach processes and increase the skills that your students will take with them.

It takes a little ingenuity, knowledge of the processes, and understanding of your materials’ characteristics to make really great projects.

The more exposure a student has to a variety of skills, the more options they have in their future. A metalworking project might just spark that one student into a career that they might not have considered otherwise.

Practical Workshop Version 2

Hearlihy’s website has had a facelift this year.

When visiting the site, most viewers will notice a rotating image at the top of the home page, which is about three key topics for Hearlihy visitors: drafting, 3-D printing, and printing technology.

When each image is selected, it opens a feature page on that topic that provides a short description, links to major product categories in the online store, and links to articles for most sections.

The biggest change, however, is the addition of the Drafting 101 section. This hosts past articles and new information together in one convenient place for those who need to learn more about drafting, architectural modeling, screen printing, and more.

New Drafting 101 section features helpful content

New Drafting 101 section features helpful content

Current articles include:

  • Why Teach Hand Drafting?
  • Drafting 101: The Basics
  • Create a Custom Drafting Kit
  • 3-D Visualization with Ortho-Box
  • Raise Funds with Printing Tech
  • Using the Mug Wrap

The smallest change appears to the right of the Store section tab: the Community tab has been renamed News, and it links to the Hearlihy In the News blog. Select this tab to find the latest information about drafting and classroom technologies, new Hearlihy products, discounts, and more.

However, we’re far from done.

Checking back over the next six to nine months is a good idea for those interested in more content – we plan to add more articles about 3-D printing and the process of screen printing. Videos are another medium we’re going to develop and add to the Drafting 101 section this year to help teachers and other Hearlihy customers learn how to better choose activities and use our products.

We didn’t want to completely overhaul the site and potentially confuse regular visitors, so it has no radical structure changes. The left product menu is still on the site, so returning visitors shouldn’t feel lost, but both new and returning visitors will easily find helpful information.

So browse the new hearlihy.com and stay tuned for additional content in 2016.

Building bridges helps student engagement

Snap_0516

SNAP!

That sound you just heard was the latest creation from one of your students breaking and shattering into tiny pieces. It was a balsa wood bridge that was carefully measured, glued, and pieced together to test the strength of the student’s design, proving how much the student learned about geometric shapes and force.

Bridge building is an activity using small wooden structures that students engineer and then build to destroy.

The destruction is not just for the sake of seeing sticks break but also for seeing what shapes and structural designs will hold the most force with the least deflection. Kids love every minute of it. It can teach engineering design concepts, mathematical principles, and the production and use of accurate drawings and meet several standards in the process.

This type of activity has been around for a long time. Most of the time, teachers will use balsa or basswood, glue, and some method to hold the pieces together while the glue dries. There are teachers who use toothpicks or paper instead of wood with super glue or white glue for the building process. Yet in the end the objective is the same, to see whose design will hold the most force using a structure tester.

Designing the Project

Bridges2_0516

Perf Inserts can make building easier, especially when used with the Construction Caddy II.

To design this project for your classroom, you can develop the parameters from your experience. This enables you to create the activity from the ground up, including the guidelines, the materials used, and the bridge testing method. You can also base the activity on what resources you have available or be creative and obtain the required resources.

If you don’t want to start from scratch, take a look at the Pitsco BridgePak. The package is available in a 10- or 25-pack, which includes glue, The Pitsco Bridge Book, and student guide sheets. There are also options at www.pitsco.com including a Balsa Bridges – Getting Started Package, instructions, materials, supporting material to guide the student through the building process, and structure testers. This can help streamline learning by utilizing curriculum developed by those who have mentored students in bridge building during their time in the classroom. This curriculum might also identify standards that are met as well.

Setting Guidelines

Bridges1_0516

The Timber Cutter is a great tool for cutting wooden sticks.

Here are some ideas for requirements to include in your guidelines: material used and quantity, the type and quantity of glue you expect them to use, dimensions, whether you will allow cross bracing, and lamination limitations. Some teachers set up a store and charge the student, using points as currency, to teach efficiency in gathering and using materials. Others provide a set amount of material at the beginning and give credit for material returned. These methods reinforce accountability as a part of the project.

Be sure to give the students resources to research the forces that a bridge will undergo. They will need to decide how to handle each of the destructive loads placed on a bridge – static and dynamic force, compression and tension, and torsion and shear.

Activity Alternatives

Do you have students that have experience with bridge building already? Have them explore beyond a standard beam bridge. If the beams are long enough for the bridge to meet the criteria set by you or the curriculum, encourage advanced students to build an arch bridge. Add string or fishing line and see how a suspension bridge can withstand the forces compared to the bridges built by first-time builders. These options are good activities for students who have been through a similar curriculum and think they know the best way to build a bridge.

Testing

Now that your students have their bridges built, it’s time to test them. Make the activity fun for yourself and for your students. If the resources are available, place a camera to show the stresses on the bridge and stream the action to a TV in the classroom so all the students can view without obstructions.

The skills that students learn during this activity range from determining structural strength to selecting material to applying construction methods. Students will learn to work under a time constraint and can work individually or with a partner, learning teamwork. The project will run smoother when appropriate constraints are placed on the student.

Bridge building can give your students opportunities to practice the engineering design process in an environment conducive to learning. They can make something, have it break, and still get a good score and learn skills that will help them prepare for life.
