CHAPTER V
COGNITIVE LEARNING OBJECTIVES
Taxonomic is effort of grouping something that are prepared and adopted by certain characteristics. Taxonomy in education known taxonomy of learning objectives. Necessary basic taxonomy of learning objectives are:
1. Need for explanation purposes terminology that is used in the learning goals because these goals serves to give direction to the learning process and determine behavior that is considered as evidence of learning outcomes.
2. As a tool that can help teachers to describe and construct the test, assessment techniques.
A. Learning Objectives of Cognitive domains
There are several taxonomy of learning objectives those are named based on the educational experts to develop, for example, the taxonomy of learning according to BS. Bloom, Gagne, Merrill, Krathwohl and others. Education experts to share learning objectives into three domains:
1. Cognitive objectives oriented to think skills include the ability to intellectually simpler with the ability to solve a problem (problem solving).
2. Affective objectives associated with feelings, emotions, values and attitudes of the heart system which indicates the acceptance or rejection of something.
3. Psychomotor objectives oriented to motor skills associated with members of the body or actions that require coordination between nerves and muscles.
A. Learning Objectives of Cognitive Domain
Bloom's Taxonomy is very well known in Indonesia and most widely used in formulating of learning objectives. BS Bloom categorizes objectives in the cognitive domain into six categories. The six categories include intellectual competence skills from simple to the most complex. Sixth is hierarchical. It means a high level objectives can be achieved when the goals at the level below (low) has mastered.
Division by BS Bloom cognitive domains are:
1) Knowledge (memory) (C1)
Knowledge of a person to recall or recognize the return of the names, terms, ideas, symptoms, formulas etc. without expecting the ability to use it.
2) Comprehension (C2)
Comprehension is that the level of cognitive ability is expecting someone to be able to understand / comprehend the meaning or concept, situation, and the facts are known. Test memorized not only verbally, but to understand the concept of matter or fact in question.
3) Application (C3)
Application is the use of abstractions in particular and concrete situations. Abstractions that can be in the form of general ideas, rules of procedure or method commonly used or technical guidance.
4) Analysis (C4)
Analysis is the decomposition of a communication into the elements or parts such that the relative hierarchy of ideas in to clear and / or relationships between ideas is described to be explicitly turn. In the analysis tends to clarify communication to indicate how communication is organized and the way communication is arranged to give the effect as well as the base and the circuit.
5) Synthesis (C5)
Synthesis is placement with the elements and parts to form a whole such, it covers the process of working with small parts, elements and so forth and assemble and combine them in such as developing a clear pattern or structure before.
6) Assessment (Evaluation)
Evaluation is a consideration about the value of materials and methods for a particular purpose. Quantitative and qualitative considerations about the sequel where the materials and methods those are used of standard assessment criteria.

B. Test grating
Making of the grating test is the first thing you need to do every learning outcome assessment tool making. By using the grating test, making questions will be controlled so as not to get out of the expected objective.
1. Definition of Grating Test
The first step in the preparation of test materials is the preparation of the test grating (test blue print). Grating is a reference or guidelines that must be followed by the test author. Grating is a matrix whose rows and columns show the specifications of the test is arranged.
A writer must be equipped with a test deployment map items that have been designed so that those items can be determined precisely for student success. In other words, the item writers must follow the constraints specified in the grid.
Preparation of grating is essentially a selection of topics that are presented as well as the determination of specification issues that must be in writing, and the number of questions that will be arranged.
2. Components of Grating Tests
The components of grating tests are:
a) Subject matter: the materials discussed in the learning process.
b) Ability aspects: the level of cognitive domain in the learning process include: knowledge (C1), comprehension (C2), application (C3), analysis (C4), synthesis (C5), and evaluation (C6).
c) Variety matter: the kinds of questions used are objective (multiple choice), and the essay.
d) Level of difficulty: namely determining the level of mastery of the aspects that will be measured by the level of difficulty of questions that are based on developmental psychology. Status is determined as follows:
Table I. The difficulty level based on the mastery level
Difficulty level
Aspects
Percentage
Easy
C1
30%
Medium
C2, C3
50%
Difficult
C4, C5, C6

COGNITIVE LEARNING OBJECTIVES
Taxonomic is effort of grouping something that are prepared and adopted by certain characteristics. Taxonomy in education known taxonomy of learning objectives. Necessary basic taxonomy of learning objectives are:
1. Need for explanation purposes terminology that is used in the learning goals because these goals serves to give direction to the learning process and determine behavior that is considered as evidence of learning outcomes.
2. As a tool that can help teachers to describe and construct the test, assessment techniques.
A. Learning Objectives of Cognitive domains
There are several taxonomy of learning objectives those are named based on the educational experts to develop, for example, the taxonomy of learning according to BS. Bloom, Gagne, Merrill, Krathwohl and others. Education experts to share learning objectives into three domains:
1. Cognitive objectives oriented to think skills include the ability to intellectually simpler with the ability to solve a problem (problem solving).
2. Affective objectives associated with feelings, emotions, values and attitudes of the heart system which indicates the acceptance or rejection of something.
3. Psychomotor objectives oriented to motor skills associated with members of the body or actions that require coordination between nerves and muscles.
A. Learning Objectives of Cognitive Domain
Bloom's Taxonomy is very well known in Indonesia and most widely used in formulating of learning objectives. BS Bloom categorizes objectives in the cognitive domain into six categories. The six categories include intellectual competence skills from simple to the most complex. Sixth is hierarchical. It means a high level objectives can be achieved when the goals at the level below (low) has mastered.
Division by BS Bloom cognitive domains are:
1) Knowledge (memory) (C1)
Knowledge of a person to recall or recognize the return of the names, terms, ideas, symptoms, formulas etc. without expecting the ability to use it.
2) Comprehension (C2)
Comprehension is that the level of cognitive ability is expecting someone to be able to understand / comprehend the meaning or concept, situation, and the facts are known. Test memorized not only verbally, but to understand the concept of matter or fact in question.
3) Application (C3)
Application is the use of abstractions in particular and concrete situations. Abstractions that can be in the form of general ideas, rules of procedure or method commonly used or technical guidance.
4) Analysis (C4)
Analysis is the decomposition of a communication into the elements or parts such that the relative hierarchy of ideas in to clear and / or relationships between ideas is described to be explicitly turn. In the analysis tends to clarify communication to indicate how communication is organized and the way communication is arranged to give the effect as well as the base and the circuit.
5) Synthesis (C5)
Synthesis is placement with the elements and parts to form a whole such, it covers the process of working with small parts, elements and so forth and assemble and combine them in such as developing a clear pattern or structure before.
6) Assessment (Evaluation)
Evaluation is a consideration about the value of materials and methods for a particular purpose. Quantitative and qualitative considerations about the sequel where the materials and methods those are used of standard assessment criteria.

B. Test grating
Making of the grating test is the first thing you need to do every learning outcome assessment tool making. By using the grating test, making questions will be controlled so as not to get out of the expected objective.
1. Definition of Grating Test
The first step in the preparation of test materials is the preparation of the test grating (test blue print). Grating is a reference or guidelines that must be followed by the test author. Grating is a matrix whose rows and columns show the specifications of the test is arranged.
A writer must be equipped with a test deployment map items that have been designed so that those items can be determined precisely for student success. In other words, the item writers must follow the constraints specified in the grid.
Preparation of grating is essentially a selection of topics that are presented as well as the determination of specification issues that must be in writing, and the number of questions that will be arranged.
2. Components of Grating Tests
The components of grating tests are:
a) Subject matter: the materials discussed in the learning process.
b) Ability aspects: the level of cognitive domain in the learning process include: knowledge (C1), comprehension (C2), application (C3), analysis (C4), synthesis (C5), and evaluation (C6).
c) Variety matter: the kinds of questions used are objective (multiple choice), and the essay.
d) Level of difficulty: namely determining the level of mastery of the aspects that will be measured by the level of difficulty of questions that are based on developmental psychology. Status is determined as follows:
Table I. The difficulty level based on the mastery level
Difficulty level
