Teacher : ok students,is there any question about my explanation?
Student :I’m mem, I’m not understand about what is mole mem.
Teacher :good question. Ok,i will explain again about mole. Mole is the unit of measurement in the international system of unit(SI) for amount of substance. Then mole is very important to learn and become the basis for doing chemical calculations.
student: Ok mem. I’m understand now. Thank you mem.
Teacher: ok, it’s not problem. Anyting else?
All of sudent silent and teacher continued..
Teacher : ok. If don’t any question. I want you tu make 2 group.
All student make 2 group and...
Teacher : Task for group 1 are relationship between mole and avogadro’s number and then relationship between mole with mass of molecular and mass of the substance. Task for group 2 are relationship between mole and molarity of substance.you can find this task in books or internet. I’m give you 1 hours to discuss about your tusk and you must make a summary that you discuss and presentation your discuss. Are you understand?
All student: ok,mem...
Teacher : Okay,now you must start tu discuss about your task.
After one hours...
Teacher : Time to discuss is over,you must collect your group’s summary.
All student collect their group’s summary and...
Teacher: Good. We will start the presentation for group 1 to explain about their discuss
Group 1: Assalamualaikum wr.wb. today,we will presentation about relationship between mole and avogadro’s number and then relationship between mole and mass of molecular and mass of the substance. The mole,abbreviated mol,is an SI unit which measures the umber of particles in a specific substance. One mole is equal to 6,022x1023atoms or other elementary units such as molecules. The mass of a substance in the multiplication of its mole mass with the mol of the substance. This means tht the mole of a substace is proportional to its mass and inversely proportional to its mole mass. When the greater the mass of the mole then the mole is getting smaller. Ok,our presentation is over, and we will open 1 question.
Other student: I’m. Whether every 1 mole of a substance is 6,022x1023 atoms?
Group 1: Yes,because it isa statute and has become law. Are you understand?
Other student: ok, I’m understand now.
Group 1: Ok. I think that’s all about our presentation and we close with Assalamualaikum wr.wb.
Teacher: Good job. Please give them applause. That’s a good presentation,we will listen explanation of group 2.
Group 2:Assalamualaikum Wr.Wb. Today,we will presentation about relationship between mole and molarity and volume of them. Molarity has relationship with mole because in the formula of molarity we use mole of the substance. And molarity states that the number of moles of substance in 1L of solution. When mole of substance is increase then molarity of the substance is increase too. If volume of the substance increase, the molarity of that substance is smaller. Ok,that all of our presentation and we will open 1 question.
Other student: I want to ask your group how to find molarity from a solution mixture?
Group 2: if you want to find molarity from a solution mixture, you must find residual mole and adding oth volumes of the solution. And you can find molarity from a solution mixture. Are you understand?
Other student: ok. I’m understand now.
Group 2: ok, i think it’s enough. If our presentation have problem i so sorry. Assalamualaikum Wr. Wb.
Teacher:ok,give them applause. You have a good presentation, and you must know about mole. This lesson is the one of indicator for your UAS. Are there any question?
All student: No mem..
Teacher: Ok,i think our lesson is enough. I’m close with assalamualaikum wr.wb.
All student: walaikumsalam wr.wb.
What is stoichiometric function?
BalasHapusIts function to: 1-Estimate the results of a reaction from a certain amount of preaksi, 2-Calculate how much material is needed, if desired a certain amount of reaction.
Hapuswhat metodh we use to teach?
BalasHapus1. comucating skill
HapusCommunication is the main activity of human in everyday life. Communication skills are the ability, intelligence, and communication skills. Communication is the capital and key suses in association and career because only with communication a good relationship can be built and nurtured.
2. Argumentation skill
Generating counterarguments is an important argument skill.Thinking about counterarguments will lead to a more thoughtful and informed consideration. For example, if you have to write an essay or an argumentative paper or if you are preparing a debate. For a more considered judgment on moral issues, one which addresses moral counterarguments, it may be useful to know something about ethical dilemmas and moral values.
3. Problem solving skill
Most problem-solving skills are developed through everyday life and experience. However, the following interests and activities may be useful in applying to high-level skills such as engineering, IT, operational research and some areas of finance.'Mind games' such as cryptic crosswords, Sudoku, chess, bridge, etc;Computer games - the best of these can involve strategic planning, critical and statistical analysis and assessing the pros and cons of different courses of action;'Practical' interests such as programming, computer repairs, car maintenance, or DIY;Working with sound or lighting equipment for a band, event or show;Academic study: evaluating different sources of information for the essays, designing and constructing a 'microshelter' for an architecture project; Setting up a lab experiment.
4. Incuiry skill
One method of teaching that is very kontruktivistik is the method of inquiry (investigation).
What approach do you use in teaching and learning process?
BalasHapusProjects, discussions, and assignments
HapusIf you want to find the molarity of the solution mixture, you should find the rest of the mole and add the volume of the other solution. And you can find the molarity of the solution mixture. Give me an example and an explanation of the statement
BalasHapusThe volume in this statement is the volume mixture between 2 solution that we mixture. For rest of the mole in example in netralitation we have same mole and have volume mixture.
Hapushow to teaching chemistry so that student so easy to understand?
BalasHapusGood teaching is not easy, and like any other skill it can only be developed with practice. A good understanding of the subject matter is important, but teaching is more than just a process of transferring information from your notes to the students'.
HapusAs an experienced chemistry student you have been able to take a body of knowledge and organize it logically in your mind; you are now able to fluidly use concepts that you struggled with in the past. Using language and arguments that you now see as obvious may prove meaningless to students who have not developed these into their working knowledge. As a teacher you should consider how your instruction can help lead a novice chemistry student through the same untangling of chemical ideas that you went through.
Best teaching practices will be discussed in more depth during TA training. Some other key points that you can begin to think about now are discussed below.
Hi indri,
BalasHapusI want to ask you,
How the formula looks for volume if known pressure and temperature ?
PV=nRT
HapusThat is the formula for your question
What is the use of stoichiometry in your life?
BalasHapusThe principles of stoichiometry can be used while cooking.
HapusIf you were almost out of a specific ingredient, you could use the principles of stoichiometry to figure out how much of every other ingredient you would need (treating the ingredient you were almost out of as the "limiting reagent").
Stoichiometry continues to be useful in many walks of life—a farmer determining how much fertilizer to use, figuring out how fast you have to go to get somewhere in a specific period of time, or just to make conversions between systems like Celsius and Fahrenheit.
