Learning Steps with a Scientific Approach
Regulation of education and culture (permendikbud) No. 81 A of 2013 attachment IV, the learningprocess consists of five main learning activities namely: Observing, Asking, Collecting Information
/ Experiments, Associating / Processing Information, And, Communicating.
Observe
In the process of observing learners are expected to be able to see what the teacher presents,
such as video or film related material, the teacher can also display images that are also related to the
material. In addition, observations can also be done at the time of the teacher to simulate.
Ask
After learners observe, then learners formulate questions on what has been displayed in the
teacher, if there are already questions on learners expected with the question that will make learners
more attention to the material and able to find their own answers to the question.
Gathering Information / Experiments
At this stage, after learners have questions gained through the observation of the media that
has been displayed teacher, then the next task of the students is to collect information, information to
answer questions that have been made, the information can be obtained from various learning sources
such as books, setudi Library, internet. This is where learners in demand to actively work together in
groups.
Associate / Process Information
After obtaining sufficient information and data, learners in their group share the task to
associate or process the information already in the can with which aims to answer the questions that
have been formulated. And display it in group reports.
Communicate
In this process learners are expected to be able to communicate with other groups about what
information is already in though in the group. This is where the essence of the scientific that learners
are expected to exchange information with other groups. So that will create condition of active
learners, and make learners become subject learn.
In the sense of a scientific approach there are several steps, according to the Government
Student :
Good morning mister ....
Teacher : Good morning child .... what's up?
Student : We want to ask about hydrocarbons ..
Teacher : ohh ... of course please child
Student : what is hydrocarbon?
Teacher : Hydrocarbons are a compound consisting of elements of carbon (C) and hydrogen (H).
Student : What are some simple examples of hydrocarbons?
Teacher : One example of a simple hydrocarbon compound is methane, with the CH4 structure formula. In carbon chemistry, it is important for us to be able to write molecular formulas and structural formulas.
Student : what is the difference of molecular formula and structure formula?
Teacher : The molecular formula represents the number of atoms of each element present in a molecule. While the structure formula describes how the atoms are tied to each other. Here will be studied about the nomenclature of the compound.
Student : oooo .... I once read a book on compound nomenclature ... I want to ask if there is more than one branch of the same, how to naming it?
Teacher : an extraordinary question ... if there are more than one same branch, then called once but begins with the number with the latin number. Examples such as 2,3-dimethyl-hexane.
Student : ooohh ... I quite understand , thank you there is time for me
Teacher : Ok child ..

What your opinion about communication skill in scientific approach ?

HapusI think the ability of communication in scientific approach is very important, because if we can not deliver the material properly and correctly then the students will not understand the material given.
HapusHow to communicate with the students to make class be more fun
BalasHapusIn my opinion, I will add a joke in the middle of the lesson so as not to be too serious.
HapusWhat is the function of hydrocarbon in daily life?
BalasHapus1. Food
HapusMonosaccharide is a simple carbohydrate that can not be hydrolyzed into smaller molecules of carbohydrates.
Glucose / grape sugar is mostly found in fruit, corn, and honey. Fructose is present with glucose and sucrose in fruits and honey.
Galactose, the source can be obtained from lactose that is hydrolyzed through our food digestion.
Disaccharide Disaccharides is a carbohydrate composed of two monosaccharides.
Maltose (glucose + glucose), can not be fermented colonic bacteria easily, it is used in baby food,
Lactose (glucose + galactose) malted milk, found in cow milk and 5-8% in mother's milk.
Sucrose (glucose + fructose), is ordinary sugar. When heated will form brown invert sugar called caramel. Used for making ice cream, soft drinks and candy.
Polysaccharide Polysaccharides is a carbohydrate composed of many monosaccharides. The use of hydrocarbons in polysaccharides in the food field such as rice, starch, corn, etc.
2. Clothes
From hydrocarbon materials that can be used for clothing is PTA (purified terephthalic acid) made from para-xylene where the basic ingredient is kerosene (kerosene). From this Kerosene all the ingredients are formed into aromatic compounds, para-xylene Para-xylene is then oxidized using air to PTA (see petrochemical process map above). From PTA which is shaped like flour detergent is then reacted with methanol into polyester fibers. Polyester ester is the synthetic yarn that looks like a thread. Almost all the uniforms that siblings wear may be made of polyester.
3.Board Field Building materials derived from hydrocarbons are generally plastic. The plastic base material is almost the same as LPG, the polymer of propylene, the olefin / alkene compound of the carbon chain C3. From the plastic material is then a kind, ranging from the roof of the house (plastic tile), furniture, home interior equipment, car bumpers, tables, chairs, plates,
4. Art field For art business, especially painting, the main role of hydrocarbons is in the oil / solvent and the solvent. Perhaps the brothers and sisters know the thinner that is used to thin the paint. While for sculpture statues, many sculptures are made from plastic or trophies, etc. Hydrocarbons used for paint solvents made from Low Aromatic White Spirit or LAWS are solvents produced from PERTAMINA Refinery in Plaju with a range of boiling points between 145 ° C - 195o C. Hydrocarbonate compounds forming LAWS solvents are a mixture of paraffin, cyclopranin, and aromatic hydrocarbons. 5. Aesthetic field Actually art also includes aesthetics. But perhaps more extensively with the addition of cosmetics. So the hydrocarbon material that is also used for cosmetic aesthetics is wax. Eg lipstick, waxing or other cosmetic mixer, pharmaceutical or shoe polish. Surely the wax for cosmetic purposes is very strict specification. Paraffin wax in Indonesia is produced by PERTAMINA UP-V Balikpapan Refinery through filtering press process. Qualification of PERTAMINA wax qualities based on quality related to melting point, color and oil content.
How do you create an active class, fun, not boring, but the learning is still running conducive?
BalasHapusIn my opinion, I will add a joke in the middle of the lesson so as not to be too serious and also give a gift to students who are able to answer questions.
HapusHow the attitudes of teachers towards students are hyperactive
BalasHapus1. Eliminate or reduce undesirable behavior Find the trigger factor of the unwanted behavior that appears. Examples of children can not sit still often walk in the classroom. Find the reason why the child can not sit still. For example, the reason is because children need attention, feel bored, want fresh air, and so forth. Eliminate or overcome the trigger factors.
Hapus2. Developing the desired behavior Good behavior must be maintained and developed for the better. To do so can be done by reinforcement. Any desired behavior will gain strength in the form of rewards. Rewards may be objects or others, such as praise.
How make understand a lazy student?
BalasHapusIn my opinion, we must first get the attention of the student then we give the material and the example with something that easily understood by the student. With the method is expected that the students understand the material provided.
HapusIn the dialogue above, what is the role of a teacher so that students can understand the material presented?
BalasHapusThe role of teachers is very important, because teachers who guide and provide knowledge to students.
