Experiential Learning Session Part 1: The Engineering & Design Process体验式学习课程第 1 部分：工程与设计过程

Part A) Design & Fabrication 《A部分）设计与制造》

In this activity, we will build a prototype mini-jet model that will be used in our upcoming experiment. While each person will be responsible for making their own mini-jet, each plane will be unique in its own way even though everyone will start from the same standardized template. For instance, the techniques used to build and assemble the mini-jet, and the approaches to strengthening and balancing the plane will very from person-to-person. Furthermore, additional customizations beyond that of the original design schematic may also be made by the engineer. As such, the combination of all these different factors will result in a wide range of planes, which will all have their own unique advantages and disadvantages. During this learning module, each person is encouraged to test their planes multiple times to see if their plane flies straight, and are encouraged to make slight adjustments to further improve the overall balance and flight performance of their mini-jet models before moving on to the next learning activity.

在这项活动中，我们将制作一个微型喷气机模型原型，用于即将进行的实验。虽然每个人都将负责制作自己的微型喷气式飞机，但每架飞机都将以自己的方式独一无二，尽管每个人都将从相同的标准化模板开始。例如，建造和组装微型喷气式飞机所使用的技术，以及加固和平衡飞机的方法都会因人而异。此外，工程师还可能在原始设计方案之外进行额外的定制。因此，所有这些不同因素的组合将产生各种各样的飞机，它们都有各自独特的优点和缺点。在这一学习模块中，我们鼓励每个人多次测试自己的飞机，看看自己的飞机是否飞得笔直，并鼓励他们在进入下一个学习活动之前，对自己的飞机进行微调，以进一步提高微型喷气机模型的整体平衡和飞行性能。

Part B) Peer Review & Evaluation 《B部分）同行评审和评估》

Now that everyone has completed their own mini-jet model, we will advance to the next stage of the project and begin the process of testing and evaluating each plane. We will start by forming small groups with 2 ~ 3 people in each group. Within these groups we will perform a “peer review & evaluation” to determine which mini-jet model is the best overall plane amongst those made by the group’s individual members. Using “qualitative observations”, the group will evaluate the overall build quality of each plane (i.e., visual assessments of the: the cut quality, general assembly, strength, & aerodynamics, etc.) of the planes that have been created. Basic testing techniques may also be incorporated into the “peer review & evaluation” process as well. This could include testing the planes to see which plane flies the furthest or straightest within a general test. Once each group has completed their peer review, they will need to select the best plane from within the group to advance to the next stage of testing.

既然每个人都完成了自己的微型喷气机模型，我们将进入项目的下一阶段，开始测试和评估每架飞机。首先，我们将组成小组，每组 2 至 3 人。在这些小组中，我们将进行 “同行评审和评估”，以确定在小组成员各自制作的飞机中，哪种微型喷气机模型的整体性能最好。通过 “定性观察”，小组将对每架飞机的整体制造质量进行评估（即，对飞机的切割质量、总体组装、强度和空气动力学等方面进行目测评估）。基本测试技术也可纳入 “同行评审与评估 “流程。这可能包括在一般测试中测试哪架飞机飞得最远或最直。每组完成互评后，需要从组内选出最好的飞机进入下一阶段的测试。

Please be advised that we are only looking at making visual “qualitative” observations at this time. We are not performing formal tests to collect numerical “quantitative” data just yet. These formal tests will be completed using the “Scientific Method” in the upcoming learning modules.

请注意，目前我们只是进行直观的 “定性 “观察。我们还没有进行正式测试来收集 “定量 “数据。这些正式测试将在接下来的学习模块中使用 “科学方法 “完成。
