Scientific approach
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.
Dialogue using 5 scientific approach
In a quiet atmosphere in classroom A, the yogic pack explains the matter of hydrogen bonding with enthusiasm. Before ending the material explanation, he lures his spirits to imagine hydrogen bonds.
Mr yogik: if you have drawn how hydrogen bonds, what is the first time?
Badrul : hydrogen bond is a kind of intermolecular attraction or between dipoles that occur between two partial electric charges with opposite polarity. And why the bonds can be so strong. How can it happen sir?
Mr.yogik: a great question. As I explained earlier this hydrogen bond occurs between compounds having H atoms with compounds containing atoms F, O, N and Cl. Why the bond can be so strong, it happens because the bonded electron pair will tend to be attracted to a more negative atom.
Badrul : the examples for hydrogen atom sir?
Mr. yogik : like HF, H2O, NH3 and etc..
Mr. Yogik : For a better understanding of the hydrogen bonds, I will form groups and each will seek what application of hydrogen bonding in everyday life. And why does the hydrogen bond occur only between H atoms with F, Cl, O and N. why not with atoms other than the one I mentioned earlier.
What is this scientific approach effective in the world of learning?
BalasHapusYes, cause the scientific approach will making creative studend and interesting learning.
HapusWhat is the effect if we do not use scientific approach in chemistry lesson?
BalasHapusThe lesson will be passive. And student will be bored if don't use scientific approach
HapusHi hud ,What constraints found during the study with scientific approach?
BalasHapusThanks for visit zelvi. One of the 5M components whose weaknesses are the most important and most crucial to my immediate overcome, is the observing component of:
HapusA. Learners are often nonchalant in observing natural phenomena, experiments. Etc.
B. The motivation of the students is still low, this is probably related to awareness of the urgency of learning IPA is still low.
C. Sometimes in the process of observation requires long preparation and implementation time, costly and relatively high energy.
D. If in observing uncontrollably will obscure the meaning and purpose of learning.
What is a dipole ?
BalasHapus
HapusPolar bonds are the dividing line between pure covalent bonding and pure ionic bonding. Pure covalent bonds (nonpolar covalent bonds) share electron pairs equally between atoms. Technically, nonpolar bonding only occurs when the atoms are identical to each other (e.g., H2 gas), but chemists consider any bond between atoms with a difference in electronegativity less than 0.4 to be a nonpolar covalent bond. Carbon dioxide (CO2) and methane (CH4) are nonpolar molecules.
