IMPROVING STUDENT ACHIEVEMENT LEARNING PART TWO
| CHAPTER II LITERATURE II.1 Definition of Learning Teaching and learning activities is an essential activity in the overall education process in schools . This means that educational objectives achieved or not depends only on how the learning process experienced by students as a protege . A fairly comprehensive understanding of learning given to Bell - Gredler ( 1986 : 1 ) which states that learning is a process undertaken by humans to get variety : abilities ( competencies ) . skills ( skills) and attitudes ( attitudes ) were acquired in stages and sustainable ranging from infancy to old age through a series of life-long learning process . Learning as a process of human , has an important position and role , both in life and modern society . In a more comprehensive view of the concept of learning can be extracted from various sources such as philosophy , empirical research , and theory . Philosophers have developed the concept of a systematic study on the basis of the reasoning and logical reality of truth , goodness and beauty . Because of that philosophy is a coherent view of the view of human relationships with the universe . II.2 Understanding Learning Difficulties . Every teacher always hoped that his students in the teaching-learning process in schools can achieve the learning outcomes as expected . In the process of teaching and learning teachers often face the problem of the students who can not attend classes with other teachers both words often encounter students who have difficulties in learning . According to Hakim (2005 : 22 ) " learning difficulty is a condition that causes interruption in the learning process of a person " . Meanwhile, according to Entang (2002 : 7 ) unsuccessful in teaching and learning to achieve mastery learning can not be returned to one factor , but to a lot of factors that can be questioned in student learning and the kind of difficulties faced by students and activities involved in the learning process teaching . And a variety of the above description can be concluded that students' difficulties in learning are the same as the inability of an individual to be able to obtain a good perubabahan after following a series of learning activities that are not running optimally . For example, an inability to concentrate in learning , inability to observe , and understand the material presented by the teacher or in resolving a matter that has been given by the teacher . II.3 Troubleshooting So that learning science can be optimally implemented in accordance with what is expected , then it must be accompanied by a lot of media props and various evaluations . Because the purpose and media props and the evaluation is to determine the success of the learning process that takes place . Media props given through science learning in accordance with the subject of our study . With frequent media display props so students can easily understand the material in learning concepts diujarkan . It is appropriate that proposed by ( Barlow , 1985; within Muhibbin Shah , 1995 , 245-246 ) which provide teachers with media consolidation props on the subject matter that has been given to facilitate students to understand and be able to learn the material further . II.4 Summary of Material 1 . nasal cavity Nose breathing is a tool we are there on the outside . In which there hairs that serve to filter the incoming air . And can be used to smell a rat . Surface of the nasal cavity contains many blood vessels so it is always warm . Nasal cavity mucous membrane is coated which is always moist . Therefore , the air will be humid and warm before getting into the lungs . 2 . Throat ( trachea ) Try to touch the front of the neck to the right what you feel ? we will feel a bit hard part is not flat . This section was built by the windpipe cartilage ring or bracelet . In the larynx are the vocal cords vibrate when air in the lungs passes through the tape . Ribbon that vibrates produces sound . The lower end of the throat branching to the left and one to the right again . Branching is called bronchi . Bronchi ramify in it to form lung bronchioles . 3 . Lungs. If we look at the picture above , our lungs brokiolus and composed of fine bubbles ( alveoli ) at the ends . Alveolus is arranged as strands of grapes , is very small and in sheathed by blood capillaries . This is where gas exchange occurs . And atmospheric oxygen bubbles in the alveoli into the capillaries and carbon dioxide in the body and carried by capillaries issued . How does air get into the lungs ? To demonstrate this , we will create a model of props breathing by using the tools we can get around we , as in the following activities 1 . Activity 1 . models of respiratory Tools and materials 1 . Used plastic bottles of mineral water ( 1.5 liter fill ) . 2 . Plastic straw . 3 . Cork stopper with one hole . 4 . Rubber sheet ( created and torn balloon ) . 5 . Balloon . 6 . Tape or plasticine ( evening ) . |
