Script of teacher and student dialogue
Learning with a
scientific approach is a learning that consists of observing activities (to
identify things you want to know), formulating questions (and formulating
hypotheses), trying / collecting data (information) with various techniques,
associating / analyzing / processing data (information) And draw conclusions
and communicate results consisting of conclusions to acquire knowledge, skills
and attitudes. These steps can be followed by creating activities.
Teacher :
Good morning my student
Student :
Good morning too, sir
Teacher : Now, I will explain about Atomic
structure. The atom consists of protons, neutrons and electrons. The nucleus of
atoms is composed of a number of protons and neutrons. The number of protons in
the atomic nucleus determines the charge of the nucleus, while the nucleus of
the nucleus is determined by the number of protons and neutrons. Subsequently
the three subatomic particles (protons, neutrons, and electrons) with certain
combinations form the atoms of an element. An atom has properties and masses
that are peculiar to each other. With the invention of atomic constituent
particles known as atomic number (Z) and mass number (A)
Student : Sir, how can I write athomic number and
mass number with the element? Could you give me a example?
Teacher : Of course, I will give you a example
Student : Then, from athomic number and mass
number how we can get a value of neutron?
Teacher : Good question, for electron can you get
from mass number – athomic number. Now, I will explain about isotop, isobar and
isoton? Have you heard it
Student : No, I don’t have sir
Teacher : Isotopes are atoms that have the same
atomic number, but their mass numbers are different. Isobars are atoms that
have different atomic numbers, but the mass numbers are the same. Isotons are
atoms that have different atomic numbers, but have the same number of neutromes
Student : Why each isotope of one element has the
same chemical properties, sir?
Teacher : It because the number of valence
electrons is the same. The isotopes of this element can be used to determine
the relative atomic mass (Ar) of the atom based on the abundance of isotopes
and the atomic mass of all isotopes
Student : Ohh oke sir thankyou, now I understood
that
Teacher : You’re welcome
In your opinion, what is more important from 5 scientific approach that?why?
BalasHapusAll scientific methods are important,because the application of scientific methods helps teachers' abilities and the application of scientific approach in learning not only focus on how to develop students' comptence in doing observation orexperiment, and also to develop knowledge and thinking skill so that can support creative activity in innovate or work
HapusDoes teacher in indonesia teach use scientific approach?
BalasHapusI think not all of them are using this method, but the scientific approach method is the most effective way ... why?
HapusBecause this scientific approach aims to: (1) improve intellectual ability, especially the ability to think achievers of high learners. (2) Establish the ability of learners in solving a problem systematically. (3) the creation of learning conditions in which learners feel that learning is a necessity. (4) get high learning outcomes (5) train students in communicating ideas, especially in writing scientific articles (6) to develop the character of learners
What is meant by neutrons, protons, electrons?
BalasHapusElectrons are subatoms that have a negative charge and these particles do not have any substructure to be trusted with ementer particles.
HapusA proton is a subatomic particle that has a positive charge.
Neutrons are subatomic particles that have a charge that is neutral and somewhat heavier than protons
is there any dissadvantage if we use Learning with a scientific approach?
BalasHapusI think there is no disadvantage because, simply, the scientific approach is a disciplinary approach and a functional science approach to a particular problem.
HapusIn a scientific approach, it is required to do the ways or steps with a certain order also to achieve the correct knowledge and logical
How to explain to students that students understand about atomic structure?
BalasHapusThe teacher's first step should be to explain the sense of atomic structure
HapusRare the two teachers should explain the development of the atom model
The third step teachers have to explain the various models of atoms
The fourth step of the teacher should explain how to determine the atomic structure based on the periodic table
The fifth step teacher should explain how to determine valence electrons
Why different atoms can have the same mass number and number of neutrons?
BalasHapusBecause the atomic number is determined by the number of protons, while the mass number is determined by the number of protons and neutrons
Hapus
