The purpose of my mini-teach is to introduce various methods of presenting the Periodic Table which identifies the various elements. I will also be introducing some terms and common phrases used in American Sign Language because most of the students I work with are Deaf and Hard of Hearing and I think that it would be most beneficial for the instructors to become familiar with these terms in the event that some Deaf and or Hard of Hearing students are in their classes.
Materials
I will begin my presentation by stating my name and finger spelling my name simultaneously.
I will introduce my presentation as Science In Sign part 17 and give the name of my Presentation: "An Introduction to the Periodic Table".
There will be ten words listed on the chalkboard "VOCABULARY" which I will "sign" for the students and have the students "sign" after me first and then by themselves.
Once the students have completed the vocabulary, I will explain the brief information to be presented in the movie "The Periodic Table" (10 min.).
After the movie has been shown, the students will be given their copies of the Periodic Table and we will discuss the scientists referred to in the film and what promoted each to begin his work. (8 min.)
The students will be given one package of characters, each facing different
directions, the hair, fingers, legs, and/or facial expressions will
indicate which column it belongs to.
The students will be told that each character must be placed in order by the identifying Characteristics.
The students will be able to see, once characters are in order, the Periodic Table will be completed. The students will discuss the Zag House for five or six minutes. Remember, science has no definite order.
The culminating activity is that the students will create elements represented on the Periodic Table< Each student will be given several toothpicks of varied lengths, gum drops (at least 20), plastic containers, and element work sheet which will identify specific elements which are to created using the gumdrops. Each student will complete their elements and tell the class what the elements are, identify the number of protons and neutrons in each element (i.e. Hydrogen=1 proton, therefore, the tooth pick would only have one gum drop on it).
The time allotted for this activity will be 15 minutes.
Performance Assessment
The students will complete a quick quiz sheet identifying specific elements
and the names of the scientists named in the movie.
There will also be time allotted for questions and answers, critique, and
methods to improve and/or change the presentation.
Conclusion
I will conclude my presentation by asking specific students to sign the vocabulary words which were presented at the beginning of the session, ask the names of the two scientists named in the movie, and remind them that as educators/ teachers in the main streamed class room, we must always use various methods to introduce topics such as the Periodic Table in ways which will hold the students interest and their attention.
I will also emphasize that science is one of the most difficult subjects for students who are Deaf, Hard of Hearing, and Hearing Impaired and that there may be times that the language and the method in which the lesson is present should be modified to meet the students’ needs and assure their comprehension of the subject matter. This will also assure the instructor that the student is 100% or at least 99% confident that he or she will pass the class or at least leave with a good working knowledge about the subject.
Rubric
Because class participation is a prime factor, the students will receive 25 points extra credit for completion of both activities.
QUIZ
10 POINTS PER QUESTION
100 - 90 A
89 - 80 B
79 - 70 C
69 - 50 D
BELOW 50 MEANS THAT THE STUDENTS NEED MORE TIME ON ASSIGNMENT
