DIALOGUE BETWEEN TEACHERS AND STUDENTS WITH A SCIENTIFIC APPOROACH

DIALOGUE BETWEEN TEACHERS AND STUDENTS 

WITH A SCIENTIFIC APPOROACH

 

His scientific approach is the scientific approach promoted by the Curriculum 2013. The steps of a scientific approach is a form of adaptation of the scientific step towards science. Principles of learning activities with curr curriculum approach 2013, namely:

1.      Learners are facilitated to find out;

2.      learners learn from various learning sources;

3.      learning process using scientific approach;

4.      competency-based learning;

5.      integrated learning;

6.      learning that is being verified that has multi dimensions;

7.      aplicative skills based learning;

8.      improving balance, continuity and linkage between hard and soft skills;

9.      learning that prioritizes learners and empowers learners as lifelong learners;

10.  implementing learning by modeling (Ing Ngarso Sung Tulodo), building willingness (Ing Madyo Mangun Karso), and developing the creativity of learners in the learning process (Tut Wuri Handayani);

11.  continuing study at home, at school, and in the community;

12.  utilization of information and communication technology to improve efficiency and efficiency of learning;

13.  recognition of individual differences and cultural background of learners;

14.  A fun and challenging learning environment.

The following is a dialogue between teachers and students based on a scientific approach
Teacher      : Today we will learn about endothermic reactions and exothermic reactions.
Student      : (Silent)                                                                                                    

Teacher      : Well today we will discuss it, who knows what is an exothermic and endothermic

                     reaction?
Student 1   : According to the book I read the exothermic reaction is a reaction that occurs with

                     the heat release from the system to the environment or the heat release reaction
Teacher   : additional?   

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    Student 1   : The endothermic reaction is a reaction accompanied by heat transfer from the

                      environment to the system, or briefly can be said as an endothermic reaction is a

                      reaction that absorbs the heat system.

Student 3   :Sorry I want to ask what is meant by system and environment?
Teacher      : Good question, The system is something that becomes the center of attention and

                     observation in a reaction, while the environment is everything that is outside the

                     system. For example, if HCl is reacted with NaOH, then the system is HCl and

                     NaOH, while the test tube, air temperature, air pressure is the environment.
Student 2   : What are the examples of each example book?

Teacher       : Burning a book is an example of an exothermic reaction and melting ice is an

                     example of an endothermic reaction.

Student 1   : What is the formula for enthalpy change?

Teacher       : Depending on the enthalpy change is ΔH = Hakhir - Hawal

                      Therefore, in an exothermic reaction where each releases heat, the oxygen content

          of the system decreases, or the enthalpy before the reaction (starting state) is

          greater than the reaction.

Hawal> Hakhir

Therefore ΔH = Hakhir - Hawal,

ΔH has a negative value, or ΔH <0

The same is true of endothermic reactions, where:

Hawal <Hakhir

And ΔH will have a negative value, or: ΔH> 0. 

Well that's just our meeting on this day I end the wassalamualikum wr.wb
