Five What is Machinery instructional design

1. Teaching Objectives.

1) Process and Method:

1.Ability to pass analysis. Determine which items are mechanical.

2.It is possible to know through comparison that machinery can reduce the difficulty of work or save effort.

2) Knowledge and Skills:

1.Know that complex machinery is made up of simple machinery, and complex machinery is also called a machine.

2.Knowing that humans have been making and using machinery for a long time, science is constantly evolving.

3) Emotional Attitudes and Values:

1.Realize that machinery is intimately related to our lives.

2.Willing to cooperate and communicate.

Two. Preparation for teaching: Preparation for teaching with a variety of simple tools.

3. Teaching process:

1) Create a situation and introduce a new lesson.

Conversation: If there is a piece in the yard, several people can't move. It's huge. What should I do if I want to move a heavy stone? Use the methods that students say to lead to the topic of this lesson: What is machinery? (2) Learn new lessons.

1.Get to know the machinery.

1) What was the first thing that came to mind when you first saw the word "mechanical"?

2) Ask students to talk about what kind of machinery do you think are in the form of group discussion?

3) Students report, other students can give supplements.

4) The teacher presents the physical objects of simple tools** and asks students to determine whether these tools are mechanical.

2.Instruct students to recognize the meaning of machinery.

1) After the student, the teacher gives affirmation. Make it clear that the simple tools shown above are all mechanical.

2) Students work in small groups to choose a simple work discussion that they are interested in: what parts of the work these tools are mainly used, what convenience they bring to people, and record the report.

3) Reveal the concept of machinery and explain the difference and connection between simple and complex machinery.

The name of the machine. Work section.

Bring convenience.

3.Instruct students to understand the role of machinery.

1) What does the role of machinery show that large stones that cannot be moved by hand can be prying-like with wooden rollers?

2) In small groups, select the tools provided by the teacher, and do comparative experiments with and without the use of mechanical energy, so as to gather the benefits of machinery to human beings. (Teachers should remind students to pay attention to safety when operating to prevent accidents).

Discussion: What would happen if we didn't have the machines like these to help people work?

4.Introduction to ancient machinery.

1) Let's read several groups of ancient simple machinery in the book** and explain human manufacturing. A long history of using machinery.

2) Analyze how ancient tools can reduce the difficulty or effort of work, and feel the wisdom of the ancestors. 4. After-class homework.

Students are asked to use their spare time to observe or investigate what other objects in our lives are simple machines and how they facilitate our lives.

Social development will become slow.

Teaching Objectives: 1.It can be analyzed and divided into simple machinery and complex machinery.

2.Through comparison, you can understand the role of machinery.

Scientific knowledge:1Know what machinery is and what machinery does.

2.Know the difference between simple and complex machinery.

3.Know that humans have been making and using machinery for a long time.

Emotional Attitudes & Values:

1.Recognize that machinery is what we create and use, and that science is constantly evolving.

2.Be proud of the history of our ancestors who made and used machinery.

3.Be brave and discover the scientific truth hidden in the tools.

Focus: Understanding everyday machinery.

Difficulty: The characteristics that the machine should have (how to judge the machinery).

Schedule: 2 lessons in total.

Preparation before class. Teacher preparation: a pair of chopsticks, billiard cues.

Process design. Lesson 1.

1. Create situations and introduce new knowledge.

Hercules Event 1: Invite two students with disparity in strength to play the "spinning the bat" competition, and the students will lead to the results, and then introduce the knowledge to be learned in this lesson "what is a machine" through the results of the competition.

Second, ** new knowledge.

a) Perceptual Mechanical:

1. Ask students to show the ** about machinery that they have filled in before class, and briefly report on the various machinery they have collected in small groups.

2 The teacher presents simple tools and **, and asks students to judge whether these tools are mechanical.

b) Explain the meaning of machinery:

1 Students agree that the simple tools presented above are mechanical.

2 Students work in small groups to select simple tools of interest and discuss: what parts of these tools are mainly working, what convenience they bring us, record and report.

3. Reveal the concept of machinery and explain the difference and connection between simple and complex machinery.

c) Revealing the role of machinery:

1 Take out a pair of chopsticks. Invite students to say if it's mechanical and why.

2. In small groups, select the tools provided by the teacher to compare the use of machines with those without machines, and experience the benefits of machines to human beings. Discuss which parts of the machine make the job less difficult and further reveal the role of the machine.

3. Observe the P2 items in the textbook to determine which ones are not machines and why?

4. Try to discuss the role of the game and machinery in the "spinning the bat" link, and talk about whether the bat is a machine. Why is it labor-saving?

d) Introduction to Ancient Machinery:

1 The teacher shows several sets of ancient simple machines** and pyramid construction** to explain the long history of ancient human beings making and using machinery.

2. Inspire students to analyze how ancient tools can reduce the difficulty of work, so that students can feel the wisdom of their ancestors.

3. Outreach activities.

Assignment: Students are required to use their spare time to observe or investigate which devices in life are also simple machines that facilitate our lives.

Machinery refers to a general term for machines and mechanisms.

Textbook Analysis Simple machinery is the development and evolution of some simple production tools created by human beings in the practice of production and labor. In addition to the levers, axles, and pulleys introduced in the textbook, he also includes inclined planes, spirals, etc.

The design intention of this course is to guide students to understand machinery as a whole through the analysis of equipment and what are the characteristics of machinery in the textbook, and to introduce students to the first and better understanding of machinery.

Learning Situation Analysis Students have seen some different machines in their daily life, and have some understanding of some machinery, but their understanding is not deep enough, and they lack systematic, one-sided or even wrong understanding. In this course, the cognitive laws of students should be fully considered, and efforts should be made to make it easier for students to achieve the teaching goals of the undergraduate program through the method of "activity-communication-activity-induction".

Teaching Objectives Process & Methodology:

By comparison, it is known that those objects are mechanical.

By comparing and understanding the use of machinery, the work can be reduced and work efficiency can be improved.

Knowledge & Skills:

Know that complex machinery is composed of simple machinery, and complex machinery is also called a machine.

Know that humans have been using and manufacturing machinery for a long time.

Emotional Attitudes & Values:

Students realize that machines are closely related to our lives.

Students are willing to work collaboratively and communicate.

Teaching focus and difficulty.

Focus: Based on students' existing experience and knowledge, discuss and summarize the characteristics and functions of machinery, and further explain what machinery is.
