Cooperative Learning Lessons Planning Guide

§  Subject Area: Chemistry “ Acids and Bases Solutions”

§  Grade Level: Eight “8”

Lesson Description:

   The acidic and Basic solution is the first chapter in unit four “Acids, Bases and Salts” for grade eight students. During this period (60 min) students will have a great knowledge about the identification of the properties of acids and bases. Also, they will come with acidity and concept of pH. To give the lesson its evaluability, the instructor prefers to apply a Graffiti strategy from the cooperative learning models and introduce the process of this model in order to discuss and summarize the topic from all the students in the class. The members will be divided into groups. Each cooperative group has one paper and different colored pins. While every group writes their note on their particular topic. Then the teacher asks each group to collect all the ideas that found in the paper to discuss, summarize and present it.

Ø  Room Arrangement:

Task Directions: 

   The duration of this session was 60 min. At the beginning of this session, I want to make a recall knowledge of the information that was taken in the previous session for about five minutes.

   After refreshing their memories, students’ brain will become ready to receive new knowledge to build upon the solid foundation being received in the previous session. That’s why students will receive a set of instructions to follow during the implementations of the model. [5min] 

   First of all, I told them that today you will be distributed into four clusters, then I started to organize the tables and groups members and separate the card's number (1,2,3,4 ) on the 4 tables. After that, I offer each student a card number and every five members having the same numbers will belong to the same clutch. Finally, they have to look at the cards to see where they have to sit. And I give each group a name. For instance, you are group A, you are group B, you are group C and you are group D. [7min]  

   Since the social interaction between each group is important to enhance their behavior than I told them that I want to put a score for the crowd that had a good respecting, accepting their friends' idea etc. … and the group that gets the high score then other groups will give them a gift. While if you are equally then you will give each other a gift also I will give each group ones from me. [5min] 

   Next, I will give each group a different topic to which they respond [1 min]. Behinds of that each group will have a reference. For a short period of time [10 min], every group in the room writes their notes on their particular topic.

   Then, I will ask them to stops, asks each group to move to another station. So, group A will go to group B, group B to group C, group C to group D and group D to group A. this will take about two minutes. Now, with each group responding to the new topic. At that moment, I will ask each group to read what their groups did and add another idea to them. Besides that, I will give them a reinforcement by telling them that set A and B work good and they respect each other, as well as they, will accept ideas from each other and use encouraging words to each other so I will give them a bonus mark for that behavior. 

When they finished this round, I will request them once again to switch their place. This process continues until a group’s original topic return to them. This will take about eight minutes.

   Once all the groups discussed all the topic, every cluster should collect, debated and summarized all the ideas that were related to their topic in a paragraph or as clear points. As soon as I will ask randomly one student from every clutch to present it [6min]. 

   In the end, I will ask them to clean the class and organize the table. And I will help them to do that, so they feel that we are one soul. In addition, I will thank them for this great session that they made. [3min] 

   During this session, I was stilling move around them, ask them if they need help, look if they do effort and monitoring them to see how their work is going on.

Positive Interdependence:

1.      Goal: each group discusses all the topics. Then at the end, they used to analyze the information of their original topic. Also, they have to adapt their-self to use social skills among others.

2.      Identity: every cluster will have a letter name (A, B, C, and D).

3.      Sequence: every crowd move from their station to another and discussed other topics.

4.      Resources:  each group will have one paper to write on it and different colored pens. Also, each group will have a reference in front of them to pick up the answer. 

5.      Tangible: the groups that show respecting others, think and wrote together. Then other groups should give them a gift and if they are equally I will give each other and I will give each group one.

6.      Environmental: each group has her own table based on their letter name and they sit in a circular way so all the group facing each other.

Individual Accountability: 

1.      Success: I was around them all the time so I help them when they ask and I monitoring their work in a respectful way so they will feel with a blameless attainment. Also, I select appropriate instructional goals and relevant activities that allow students get the experience from it. 

2.      Concerns: I told each group to write their notes in 10 minutes so they do more effort on their work. And when they replace their place, I probed them to read and add new notes to their friends’ ideas.

3.      I asked every group to discuss summarized and present their original topic.

Criteria for Success: 

   Academic and social goals are the criteria that lead reaching the high achievement of success. Concerning the social goals leads to reach directly the academic goals by let students listen and wait for their turns to present what they summarized.

Evaluation of:

Ø  Academic:

o   Acidic solution changes the color into red color and colorless, respectively, with:

1.      Blue litmus paper, phenolphthalein

2.       Phenolphthalein, blue litmus paper

3.      Red litmus paper, blue litmus paper

4.      Phenolphthalein, red litmus paper

o   Basic solution changes the color into blue and pink color, respectively, with:

1.      Blue litmus paper, phenolphthalein

2.      Phenolphthalein, blue litmus paper

3.      Red litmus paper, phenolphthalein

4.      Phenolphthalein, red litmus paper

o   We measure the acidity and basicity by using:

1.      Voltmeter

2.      pH mater 

3.      Ammeter

o   The pH of acids and base is:

1.      >7, <7 

2.      = 7

3.      <7, >7

o   Acid and base solution is a good conductor of electricity because they are: 

1.      Ions

2.      Neutral

o   The basic solution usually used to:

1.      Make the solution more acid

2.      Make the solution basic 

3.      To neutralize it

o   Acidic solution reacts with active metals to produce:

1.      Hydrogen gas

2.      Carbon dioxide gas

3.      None of the above

o   The production of carbon dioxide is because:

1.      The acidic solution reacts with carbonate 

2.      The basic solution reacts with carbonate 

3.      The acidic solution reacts with active metals 

Ø  Social Learning “In Small Group”:

o   Do you feel that your friends respect you in a group?

1.      Yes 

2.      No

o   Do you feel that you work, share the information together?

1.      Yes 

2.      No

o   Do you feel that and your friends accepting your ideas?

1.      Yes 

2.      No
