reasoning ability
Eureka Education. The common dictionary Indonesian of Ali (1995: 681) is specified argument, as a result of a thought or consideration of proper, fair and reasonable (logical). Reasoning is a mental process the minds of some fact or principle in developing. People mainly think a being, feel, act and act. Settings and actions are rooted in the knowledge acquired to the activity of thinking. Reasoning produce knowledge that leave with the activity of thought on reflection.
is assigned as an activity of thinking, has certain characteristics that argument. The first feature is the existence of a setting that is called widely logic. It can be said that some form of reasoning has its own logic, or it can also be concluded that the activities of the argument is a logical thought processes, where logical as an activity here interprets the thinking of thinking in a certain pattern. The second feature of the reasoning is the process of analytical thinking. Reasoning is a thinking activity, based on an analysis used and context for the analysis of logic or reasoning relates. Scientific reasoning is an activity that uses the analysis of the scientific logic and reasoning, and others. Without a pattern of thinking that there will be no activity of thought, based on certain steps.
( Only Susanna 00: 11 ) suggests that there are five reasoning that:
a. Proportional Reasoning
proportional reasoning is a source of qualitative structure that allows the understanding of a complex physical system that includes a lot of factors. One example is the understanding of the issues, the proportion and ratio based. The formal thinker capable proportional reasoning, a proportional relationship between weight and volume is proportional to the three-dimensional reasoning of two-dimensional, develop proportional reasoning transmission to estimate the size of an unknown population.
b. Control of the variables
The development of the ability to control variable is an index of mental development. Formal thinkers can assign and control certain variables of the problem. The ability to control the variables is one of the features of the formal argument. Thinkers realize formally that should at the time of the experiment is able to control all the factors that may affect the variables of the respondents, and only one variable at a time when variable manipulations change variable response.
c. Reasoning probabilistic
reasoning probabilistic occurs when an application uses the information to decide if a conclusion is probably true or not is likely and the things that have the possibility of calculating the odds ,
d. Correlational reasoning
correlational reasoning is defined as a pattern, think about the strength of the relationship of reciprocal or reverse to determine relationship between the variables, were reviewed by other variables. Correlational reasoning involves identifying and penverifikasian antar variable.
e. Combinatorial reasoning
national argument combination is the ability to consider all possible alternatives in certain situations formal thinker when a problem could be solved, to use a combination or factors that may be associated with the problem.
