Dialogue
of teachers and students
SCENARIO
Teacher : Asalamu Alaikum wr.wb.
Teacher : Asalamu Alaikum wr.wb.
Student : Wasalamu Alaikum wr.wb
Teacher : Today I have 3 mixed images. Please help me put this picture in front of the board. (Students and teachers put charta in front of the blackboard) Here are 3 pictures. (While showing pictures). The first image of syrup, both milk and coffee. I will ask you to differentiate and classify which mixtures include solution, colloids and coarse suspensions. So our topic today is about solutions, colloids and rough suspensions. Your task is to define, explain and classify based on the three images. Please think of yourself, what are the differences between the properties of these three mixtures based on particle size, physical appearance, phase count, stability when separated and the way of separation.
Student : yes miss
Teacher : Before I ask first, This picture includes what mixture, solution, colloid or rough suspension?
(Pointing at the image of syrup)
Student : solution miss .
Teacher : What about this one?
(Pointed to the milk image)
Student : Colloid Bu.
Teacher: Right. If this one includes what mix?
(Pointing to a coffee image)
Student : Rude Suspension Bu!
Teacher : wahh, my students are all great! Now please you form a group of 2 people to discuss the differences of these 3 mixtures based on particle size, physical appearance, phase number, stability if separated, separation mode and other examples of this mixture. The division of the group begins.
(Students sit in groups, then the teacher distributes LKS about the difference of solution, colloid and rough suspension to the groups that have been made earlier)
Teacher : I have LKS, your job is to discuss with your friends then write on the worksheet that I have provided.
Student : Yes miss .
(Students discuss and write down the colloidal difference for about 15 minutes)
(Then the teacher asks the couples to share with the whole class)
Teacher : Please the group of couples who are here, try to tell what you have discussed?
(One of the groups mentions what are the differences from solution, colloids and rough suspensions).
(Teacher again asks the random group to share the results discussed earlier).
(Master completes the answer from the discussion).
(Teacher asks the student to write down the result of the discussion).
(Master with students concludes from the activity).
Teacher : So, what is the conclusion of today's lesson?
Student : In conclusion, there are 3 kinds of mixture, the first solution, colloid and rough suspension.
Teacher : Yes Good, if the others, what is the conclusion?
Students : The mixtures of solvents, colloids and coarse suspensions can be distinguished by their particle size, physical appearance, phase count, stability if separated and the way of separation.
Teacher : Try A's, please repeat what the conclusion was?
A : There are 3 kinds of mixture, the first solution, colloid and rough suspension. The three types of mixtures can be distinguished by their particle size, physical appearance, phase count, stability if separated and the way of separation.
Teacher : Yes good! For the next meeting we will discuss about the types of colloids and experiments on the properties of colloids.
Student : yess miss .
Teacher : Do not forget to read the book. I close by saying the words Hamdallah.
Student : Alhamdulillah.
Teacher : If there is one word please forgive, I end with wassalamu alaikum wr.wb.
What is the difference between learning resources and teaching materials?
BalasHapusThe Main Differences of Learning Resources and Teaching Materials
HapusLearning resources are the raw materials for the preparation of teaching materials. To be presented to learners and learning resources should be in though first. While the teaching materials are ready materials for students to learn.
Learning resources is everything new has the possibility to be a resource or have the potential to generate learning process. While the teaching materials is something that has been actually designed consciously and systematically for the achievement of the students' competencies as a whole in the learning activities.
The so-called teaching materials are all books or audio, video and computer programs that contain subject matter that is purposely handled systematically. If it is not systematically designed although it contains lesson material then it can not be called teaching material.
Why in the learning process should teachers have an approach to their students?
BalasHapusThe teacher's approach is the process, the way or the approaching actions of a teacher to the learners to create an effective and efficient learning process, in teaching, the teacher must be clever to use the approach wisely and wisely, the teacher's view of the students will determine the attitude and deeds. Every teacher does not always have the same views in assessing students, this will affect the approach that teachers take in teaching.
HapusTeachers who view students as different from other students will be different from teachers who view students as being the same and there is no difference in everything, so it is important to straighten out the mistake in looking at each student, in view of the students it is better to be seen that each student has Different personalities, so teachers can easily approach the teaching
Plis mention to me the difference between acid and base!
BalasHapusThe most striking 1. difference in acid and base flavors lies in the taste of both. Sour acids, as the name implies must have a sour taste if tasted with the tongue. A simple example is vitamin C which contains ascorbate compounds, when you suck this substance, you will definitely feel a strong sour taste. While alkaline substances generally have a bitter taste. If you do not believe it, put a little bath soap into your tongue. The unbearable bitterness will surely be instantly felt.
Hapus2. Lakmus Paper Litmus paper is the most commonly used acidity indicator. Litmus paper itself there are 2 types, namely red litmus paper and blue litmus paper. Compounds or acidic substances will generally be able to redden the blue litmus paper and not change the color of red litmus paper. While the compound or alkaline substances will generally be able to brighten red litmus paper and do not change the color of blue litmus paper.
3. Differences in Nature Differences of acids and bases can also be seen from its nature. The nature of the acid is corrosive or can erode other objects (especially metals) that come into contact with it. While the basic properties are caustic or can damage the skin. Both the properties of acids and bases you must understand if you are in the laboratory. These properties are very dangerous if you do not pay attention to health and safety.
