工程设计过程 - 学习,创建,制造,赚取徽章

简介:工程设计过程 - 学习,创建,制造,赚取徽章

I love the idea of scout badges. Each badge is a tangible reminder of a newly acquired skill, an achievement or the willingness to work hard and learn. Badges are cool. I wanted to incorporate them into my classroom, however custom made badges are expensive and I wasn’t sure how the kids would display them. I also wanted badges that recognized a cumulative set of skills. Learning is a series of activities that fit together, like a puzzle. A puzzle! Puzzle badges would allow students to celebrate each step of their learning. I loved the idea, but realized I would never have enough time to make a set for each student - so the first step to earning your badges would be making your badges. The activity was a perfect fit for teaching the engineering design process

Step 1: Identify the Problem

一个难题是学习的好类似,都需要零件来融合在一起。结束难题始终是庆祝的原因。应该庆祝学习!在侦察中,徽章被用来承认和庆祝成就和学习新技能。您能设计一个拼图徽章来庆祝课堂学习吗?


步骤2:研究

为了启动该项目,我带来了女儿的女童子军背心,该背心既有组织补丁和徽章,玩具警长徽章和制造商Faire,学会了焊接技能徽章。作为一个小组,我们提出了以下研究问题。


什么是徽章?

我们小组中的任何人曾经赢得过徽章吗?

What materials can be used to make badges?

如何显示或附加徽章?

What is the difference between a patch and a badge?

徽章如何获得?

Would students like to earn badges?

徽章最常见的尺寸是多少?

什么是数字徽章?


步骤3:要求和约束

对班级的一项调查确定,学生希望赚取可以附加到背包的徽章。

Initial requirements

  • 有趣的设计,丰富多彩
  • 2英寸或更小
  • Sturdy material
  • 徽章必须像拼图一样连接
  • Easy to attach, no sewing or making holes in backpack
  • LED会很有趣
  • Easy to follow rules for earning the badge (fair)

Constraints

  • 我们的班级没有3D打印机或激光切割器
  • 我们的班级不允许焊接
  • Our class has only basic sewing skills




步骤4:确定徽章难题中的碎片数量

该项目的目的是了解和应用工程设计过程。因此,我决定这个难题应该有六个。我让学生们发现了六个连接的拼图。这是我的第一个“啊哈时刻”。相互联系的难题创造的形状都是不同的,我的一个学生说:“太糟糕了,我们将无法在学习难题中添加更多作品。另外,一些纸板已经弯曲了。因此,我们认为纸板的碎片将限制连接更多学习的机会,并且不符合学习材料的要求,因为它们很容易破裂并且无法弄湿。我订购了1.5英寸的木质拼图,没有任何末端,满足2英寸或更小的需求,坚固的材料和徽章必须像拼图一样连接



步骤5:创建一个有趣的设计

在我们的研究中,我们发现了几个免费程序s to design digital badges and we studied scouting badges. One thing that we noticed was that badges in a similar area of knowledge, such as nature, had the same background colors or borders. Most had icons or pictures and the digital badge had words too. I gave each student 6 wooden puzzle pieces, and asked them to put their pieces together. It was really interesting, some kids put them in a rectangle, but others put them in a straight line. Initially, I was thinking that we would work in groups to design a piece for each step. However, we realized that each piece would have to be linked to the surrounding pieces to create a picture for the puzzle. Someone said that the pieces reminded them of the panels in a comic book. Someone else said, everyone learns differently, so each person's badges should look differently. The initial requirement list was modified -A fun design that shows how you remember each step of the engineering process and creates a picture on the puzzle. The students traced their puzzle pieces on graph paper so they could develop their designs. (Save time, have them make two or threes copies)


Step 6: Not Just a Badge But Wearable Technology

My students loved the idea of the maker faire to learn to solder a badge that had an LED. If one light is good , six lights are better! This would also meet the initial requirement of an LED would be fun. It also added great opportunities for prototyping, testing, resigning, communicating, prototyping, testing, resigning, communicating…..and working with the constraint our class is not allowed to solder.


步骤7:钻孔

一旦学生绘制设计并标记了每个拼图上LED的位置,就需要钻孔。我决定要钻孔以节省时间,并且我担心的是学生安全钻孔的学生。我发现钻孔的最好,最快的方法是让学生放一点点胶(请务必在每块上唱“只是一个点,不是很多''),然后将其粘在纸盘上,然后钻孔纸板。对于5毫米的LED,我使用了15/64,这使LED可以贴合。将碎片粘贴到盘子上的额外好处是,它将每个学生的作品整合在一起,使他们更容易绘画和绘制设计。


步骤8:使难题

我希望每件作品都有工程设计过程的一步。因此,我们审查了这些概念并讨论了每个步骤的选项。例如,可以互换构建,创建,构建,制造,制造,制造,原型。我们尝试的第一个设计选择是Sharpie标记,但是未完成的木材导致Sharpie标记散布并流血。极好的 - 解决问题的另一个机会。一层丙烯酸涂料既提供了统一的背景,也提供了绘制设计的表面。作为课程,我们认为每个人的工程设计过程难题都是浅蓝色,因此您可以告诉您正在展示的主题。每个学生都创建了自己的设计来说明步骤。



Step 9: Sealing the Design

将纸板上的碎片分开。用高光泽的mod podge涂漆。

Mod Podge产生了出色的硬光泽饰面,使徽章看起来与搪瓷销相似。但是,它需要时间干燥。我让孩子们在星期五绘画,以便在星期一之前完全干燥



步骤10:创建LED电路

可以在没有LED的情况下制作拼图徽章。但是,我的学生很高兴能亮着徽章。他们还希望每件作品都有一个开/关开关,因此,如果您只赚了一块,它仍然会点亮,而不必赚取所有零件,然后才能点亮。如果您的学生从未与LED合作,请务必增加探索时间。最简单的起点是将LED的腿滑到按钮电池上,并让学生弄清楚较长的腿是正的。在一条腿下添加一小张纸作为开关。接下来,让他们将几个LED添加到电池中……一旦他们探索了LED和电池,就会引入电池持有器。我使用的电池持有人是有线的,这使学生可以无焊接制作电路。让学生将电池放入持有人中,以关注正 /负指标。我让学生在电池持有人前面标记正 /负线。 Next , the wires need to be stripped. The wires were extra long which provided ample length for mistakes. To save time, I cut and stripped most of the wires while the students were working on their designs, because the puzzle pieces are so small the wire only needs to be about 1.5 inches. Each student only needed to strip one set. To build the circuit, wrap the wire securely around the leg of the LED- pay attention to the positive and negative wires and LED legs. Wrap a small piece of tape around the leg and the wire to secure it. Test! It will come undone when the students are wiggling it into the puzzle piece. EXCELLENT- another opportunity to redesign! A drop of hot glue, before the tape is wrapped around the leg of the LED, was the solution most of my students used.



Step 11: Add the Magnet

最初的要求之一很容易附加,没有缝纫或背包中的孔。根据我们的研究,学生决定使用磁铁。该决定为测试和重新设计提供了很多机会。粘合剂工艺磁铁不起作用,磁带不起作用,刚磁铁确实可以工作。但是,将磁铁连接到电池持有器的背面实际上是一个困难的步骤。磁铁必须牢固地附着。不幸的是,热胶,液态胶或胶粘胶将无法工作。真正效果很好的唯一胶水是超级胶水。很多测试!很多重新设计!



Step 12: Add the LED Circuits to Puzzle

Insert the LED from the back of the puzzle piece, adjust the wires, use liquid glue to attach to the puzzle piece. I was going to cover the wires, but the kids wanted them to show and it was their project.



步骤13:赚取徽章的要求

我的目标是让学生理解和应用工程设计过程。对我来说很明显,他们已经赢得了徽章。但是,为了满足易于遵守规则以赢得徽章的初步要求(公平),我要求每个学生编写工程设计过程的步骤,并举例说明他们如何使用它来创建拼图徽章。我喜欢每个学生都明确地提醒了新获得的技能,成就和努力工作和学习的意愿。徽章很酷!
