Script of teacher and student dialogue

The scientific approach is the scientific framework of learning that is carried by the Curriculum 2013. Steps on a scientific approach is a form of adaptation of scientific steps in science. The learning process can be matched by a scientific process, therefore the 2013 Curriculum mandates the essence of a scientific approach in learning. The scientific approach is believed to be a golden tool for the development and development of students' attitudes, skills, and knowledge. In approaches or work processes that meet the scientific criteria, scientists are more concerned with inductive reasoning than deductive reasoning. Among the saintific approaches are:

1. comucating skill

Communication 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). In this method students are really involved to actively think and find the understanding they want to know. In this method of learning students are involved in the process of discovery through data collection and hypothesis testing. In general, Inquiry is the process by which scientists ask questions about the nature of this world and how they systematically seek answers.

5. Contracting skill

The ability of contracting is the ability to be able to arrange or process everything so that it can be a capability that helps in concluding and so on.

Here is an example of a dialogue between teacher and student regarding the chemical reaction :

On Monday deni and dina are out of class before chemistry learning.
Deni: Today we will learn what is with Mr.Al?
Dina: do not you remember, we will learn about chemical reactions with 5 scientific approach?
Deni: So we will discuss 5 scientific approaches?
Dina: not so den, but we study chemical reactions, but we are required to use 5 such scientific approach in learning.
The bell enters the class, they enter the classroom.
Teacher: assalamu'alaikum, good morning all?
Deni, Dina, etc.: good morning Mr.
Teacher: before you start learning, have you learned what I ordered last week?
Deni: I'm mr, have a little. Eh
Dina: I'm mr. ready.
Teacher: good, good if you've studied at home so we will be easier in learning this time. Try who knows what we will learn?
Dina: I know sir, we will study chemical reactions with 5 scientific approach.
Teacher: okay, I will start a chemical reaction material, please listen, if there is something to ask, immediately ask yes. Chemical reaction is a process whereby new substances, the reaction product, are formed from some of the original substances called reagents. Usually a chemical reaction is accompanied by physical events, such as: color change, sediment formation, release of gas and energy release and energy absorption. One example of a chemical event we can see is combustion, for example the combustion of ethane gas (LPG with air). In this combustion process required ethanol and oxygen as the base material, which will then produce carbon dioxide and water. In this case ethanol and oxygen are referred to as reactants (reactants), whereas carbon dioxide and water are called reaction products (products). Examples of these chemical reaction events are generally also written in a reaction equation. A chemical reaction equation is a combination of symbols representing a chemical reaction. The reactant formulas are placed on the left and the reactions are placed on the right. Between the two sides are combined with the sign of equality (=) or arrow (→). At the time of the chemical reaction, there are observable changes to know whether the substance reacts or not. All chemical changes are certainly parent on the law of preservation of energy laws and the law of mass energy preservation. The fundamental fundamentals underlying all chemical change are theoretical chemistry areas, the correlation between the concept of elements and compounds, with the laws formed above being obtained in Dalton's Theomic Theory, the first modern theory of atoms and molecules as fundamental particles of substances that grow from this theory. The most important thing from the Dalton atomic theory that can now be accepted, namely:
1. Atom is a building unit of all kinds of material
2. Atom is a small part of an element that still has the same properties with its elements.
3. In chemical reactions, atoms are not destroyed, not created and can not be converted into atoms of other elements.
Chemical reactions are simply rearrangement of the arrangement of atoms involved in the reaction.
. Well does anyone want to ask before my material continue?
Deni: I want to ask sir, so what are the changes that happen in chemical reactions?
Teacher: good question deni, so If there is a chemical reaction, can be observed 3 kinds of changes, namely:
A. Change of nature
B. Change of order
C. Energy changes
Dina: What are the examples of chemical reactions in our environment Mr.?
Teacher: One example of a chemical event we can see is combustion, for example the combustion of ethane gas (elpiji with air). In this combustion process required ethanol and oxygen as the base material, which will then produce carbon dioxide and water. In this case ethanol and oxygen are referred to as reactants (reactants), whereas carbon dioxide and water are called reaction products (products). Examples of these chemical reaction events are generally also written in a reaction equation.
Deni: I want to add Mr., to my knowledge that the chemical reaction equation is a combination of symbols representing a chemical reaction. The reactant formulas are placed on the left and the reactions are placed on the right. Between the two sides are combined with the sign of equality (=) or arrow (→). At the time of the chemical reaction, there are observable changes to know whether the substance reacts or not. As Mr. has responded to my question.

Teacher: good answer deni, okay dina how is that enough? I will proceed further material if it is.
So Chemical change is a change that produces new substances. New substances produced there are those who can return to their original form and some are not able. Example 1: Reduction of CuO: When black carbon and black copper oxide are heated together the Cu2 + ions are reduced to metallic Cu and a gas is evolved. When the gas is collected in Ca (OH) 2 a white precipitate of CaCO3 is formed. The reaction which involves the reduction of Cu2 + ions by carbon which is oxidized to CO2.
Example 2: Formation of Silver Crystals: When a copper wire is placed in a solution of AgNO3, the Cu reduces Ag + to metallic Ag. At the same time, Cu is oxidized to Cu2 +. As the reaction progresses Ag crystals can be seen as the result of the formation of Cu2 + ions.
Dina: Mr. I want to ask again, if there is a result of a chemical reaction there must be a cause that causes it, what is it?
Teacher: very good, so The causes of chemical reactions include:
1. Occurs due to burning.
2. Occurs due to mixing of substances.
3. Occurs due to the flow of electricity.
Deni: Mr, what chemical reaction can be done to imitate something in our environment? What kind of example?
Teacher: In everyday life his example is a traffic light where we can perform experiments in the laboratory, the experiment is named the color change of the solution. Has anyone heard of the experiment?
Deni: I am Mr., this experiment is more emphasis on the kinetic theory of gas molecule, where when the solution has been made to change color then when the chemical flask is shaken it will change color from red, green, yellow then red again.
Dina: well, have you ever seen it?
Deni: I just saw it on youtube din, and it looks like it's really amazing just by watching it.
Teacher: it is true what we say, in more detail that the solution we mix is ​​dextrose (glucose), NaOH, Aquadest, and Indigo (carmine indicator 1%). So the color of the initial solution is yellow, if the gourd is shaken slowly it will become red, and if shaken it quickly will be green.
Dina: so I can conclude that the color change is due to dextrose alkaline and oxidation process in solution, when the pumpkin is moved slowly or rapidly then a lot of oxygen comes in, so there is a change of color.
Teacher: good. Looks like we can already draw conclusions from what we learn. Who can conclude?
Deni: chemical reactions are caused by Mr. , In addition there are many chemical reactions around us.
Dina: true Mr., besides the chemical reaction has advantages and can be utilized in everyday life.
Teacher: well I think today's learning is over, and I end, good morning. See you next week.
Dina, deni, etc.: good morning also mr, bye.

thanks for reading.
