The difference between direct and indirect speech

Direct speech is when we report what someone says by repeating the exact words. In writing, we use inverted commas:
David: I have to talk to you about something. (original statement)
"I have to talk to you about something," said David. (direct speech)
Michelle: I'll call them tomorrow. (original statement)
Michelle said, "I'll call them tomorrow." (direct speech)
Indirect speech (also called reported speech) is when we give the same meaning of what someone says without repeating the exact words. In this case, we do not use inverted commas and certain changes may be necessary:
David: I have to talk to you about something. (original statement)
David said he had to talk to me about something. (indirect speech)
Michelle: I'll call them tomorrow. (original statement)
Michelle promised she would call them the next day. (indirect speech)
We also use indirect speech when we report inner thoughts:
I had no idea where my keys were. (Where are my keys?)
She knew that the lock had been changed. (The lock has been changed.)

passive voice definition


One of the two “voices” of verbs ( see also active voice). A verb is inthe passive voice when the subject of the sentence is acted on bythe verb. For example, in “The ball was thrown by the pitcher,” theball  (the subject) receives the action of the verb, and was thrown  isin the passive voice. The same sentence cast in the active voicewould be, “The pitcher threw the ball.”
Note It is usually preferable to use the active voice whereverpossible, because it gives a sense of immediacy to the sentence.

Titanium Lyric's
     by David Guetta feat Sia     


You shout it loud, but I can’t hear a word you say
I’m talking loud, not saying much
I’m criticized, but all your bullets ricochet
you shoot me down, but I get up
I’m bulletproof, nothing to lose
fire away, fire away
ricochet, you take your aim
fire away, fire away
you shoot me down, but I won’t fall
I am titanium
you shoot me down, but I won’t fall
I am titanium
Cut me down, but it’s you who have further to fall
Ghost to-own and haunted love
Raise your voice, sticks and stones may break my bones
I’m talking loud, not saying much
I’m bulletproof, nothing to lose
fire away, fire away
ricochet, you take your aim
fire away, fire away
you shoot me down, but I won’t fall
I am titanium
you shoot me down, but I won’t fall
I am titanium
I am titanium
I am titanium
Stone hard, machine gun
Fired at the ones who run
Stone hard, though as bulletproof glass
You shoot me down, but I won’t fall
I am titanium
You shoot me down, but I won’t fall
I am titanium
You shoot me down, but I won’t fall
I am titanium
You shoot me down, but I won’t fall
I am titanium
I am titanium
I am titanium

Sorting Arrays
* Definition:  Sorting is the process of putting data in order;
either numerically or alphabetically.

 
It is often necessary to arrange the elements in an array in numerical order from highest to lowest values (descending order) or vice versa (ascending order).  If the array contains string values, alphabetical order may be needed (which is actually ascending order using ASCII values).
The process of sorting an array requires the exchanging of values.  While this seems to be a simple process, a computer must be careful that no values are lost during this exchange.  Consider the following dilemma:
 Suppose that grade[1] = 10 and grade[2] = 8 and you want to exchange their values so that grade[1] = 8 and grade[2] = 10. You could NOT just do this:

grade[1] = grade[2];
                                               grade[2] = grade[1];    
  // DOES NOT WORK!!!

In the first step, the value stored in grade[1] is erased and replaced with grade[2].
The result is that both grade[1] and grade[2] now have the same value.  Oops!  Then what happened to the value in grade[1]?  It is lost!!!
In order to swap two values, you must use a third variable,(a "temporary holding variable"), to temporarily
 hold the value you do not want to lose:
          //swapping variables 
                                     temp = grade[1];     // holding variable
    grade[1] = grade[2];
grade[2] = temp;

This process successfully exchanges, "swaps", the values of the two variables
(without the loss of any values).
  Remember the example in class of the two horses switching stalls!!
Ways to sort arrays:
There are literally hundreds of different ways to sort arrays. The basic goal of each of these methods is the same:  to compare each array element to another array element and swap them if they are in the wrong position.

The bubble sort is one of the easiest algorithms to understand and we will begin our investigation with this sort.

CHAPTER I
INTRODUCTION


1.1  Background

Developments in science and technology more rapidly. This phenomenon led to competition in many areas of life, one of them in education. To produce the human resources quality, it is necessary to improve the quality of education.
 For the process of achieving optimal learning outcomes, we need a means of education or learning media. Application of instructional media should be able to train the ways of acquiring new information, select it and then process it, so there is an answer to a problem.
Science and technology to keep pace with the needs of the community drove rapidly evolving. Therefore, human resources either individually or in groups to master science and technology. If not, people will be left behind and lost in a world that is increasingly fierce competition. During its development, appearing in a variety of media types and formats. Developed many types of media these days is a computer media.
 The progress of computer media provides several advantages for the production of audio-visual activities. In recent years computer received great attention due to its ability to be used in the field of learning activities. Coupled with the network technology and the Internet, the computer seemed to be excellent in learning activities.
 Based on the above statement, I am trying to write a paper entitled "The Role of Computers in Learning".

CHAPTER II
LITERATURE REVIEW


2.1 Definition of Computer
The computer comes from the Latin, computare that count. Because of the breadth of their field of computer science, experts and researchers differ slightly in defining computer terminology :
                                Robert H. Blissmer the Annual Computer books, Computer is an electronic device that is capable of performing several tasks such as receiving input, process the input earlier in accordance with the program, save the commands and processing results, and provide output in the form of information.
                                Donald H. Sanders in the book Computer Today, Computer is an electronic system that manipulates data For fast and precise, and designed and organized in order to automatically receive and store input data, processes it and produces an output under the supervision measures, instruksi2 programs that are stored in memory (stored program ).
                                Hamacher et al, in the book Computer Organization. Computer is a fast- electronic calculating machine can accept digital input information, process it in accordance with a program that is stored in memory and generate output information.
                                Fuori found a computer is a data processor that can perform large calculations quickly, including arithmetic and logic operations, without human intervention.
So it can be concluded that the computer is a electronic device that consists of a command input, input processing tools, and output devices that provide information and work automatically.


2.2 Development of Computers
The development of computer technology in particular, is so rapid and highly influential on the world of learning. The use of computers in schools is one example to improve the quality of educational institutions, because the school is able to improve access to computers, speeding up the process and reduce the administrative bureaucracy conventional.
Revolutionary technology makes the computer more and more clever, compact, and easy to use. Originally computers used to help solve complex arithmetic calculations. However, with the rapid development of technology, the computer can be used for word processing, data processing and image processing in various fields.
Advances in computer technology made ​​into a fast-paced activity and make the world be like without limit. Various types of information can be accessed quickly and accurately. A wave of change is so rapid was able to force the education sector to use the computer as a learning medium. Technological revolution must also be balanced with the renewal of education and learning.
The influx of information technology, especially computers, have a lot of change orders and the role of education. For example, former teacher is the primary source of information for students. However, with the presence of computers and the Internet have made the teacher is not the only learning resources. With the presence of computer technology led to learning can be done individually and accessed anywhere.

2.3 Impact of Computers in Learning
In the education sector and computer learning has positive and negative impacts. The positive impact of computers that can assist in facilitating student learning, even to motivate and accelerate learning. And with the development of computer programs that have been specifically designed to help learning be more effective.
While the negative impact of declining interest in learning computer is caused because the entertainment applications that make students more than learning to use the application, and the computer is able to make the students very mechanical like a robot and who lack social skills. There are several factors that make a person into a mechanical man because of computer technology in education and learning :
                                            Computers tend to isolate
     Learning through an intermediary machine (computer, video, TV, floppy disks, etc.) can facilitate cognitive knowledge for users. But through machine learning has turned out to socially isolate users, since users only interact with the machine. Frequent interaction or using an intermediary machine causes decreased social skills.
                                            The computer tends to make people physically fasif.
     Preparation of technology-based learning programs still tend to regard verbal learning, linear, rationalistic, and only a brain. By not getting people physically involved computer-based learning just tapped portion of human intelligence.
                                            Computer only fit one learning style.
     Learning with the help of a computer is only suitable for one style of learning, because learning is a computer-assisted learning making programmed.
                                            Computers tend to be based media and not based on experience.
     Computer-assisted learning with typically programmed not by research or field experience, as learning with the help of computer designed for the needs of the media and the market.

2.4 How to be an Effective Utilization of Computers
There are several ways to utilize the computer as an effective learning. Computers can provide maximum results if it is designed to create a learning environment that is designed to :
                                           Collaborative, social nature of learning. This can be done by creating learning for two or more people.
                                           Playing and learning is the best way to start learning.
                                           Provides many options. Learning styles through a computer program designed to provide a lot of options like choosing colors, materials, voting by combining various elements in order to get a variety of learning styles.
                                           Making learning programs must be based on real experience or based on those research results.
From a variety of learning how to use the computer for, computers tools that build effective learning. The role of educator or parent is needed to control the learning progress.

2.5 Type in Computer Applications
Selection of software or application program is one that must be considered in the study. As an illustration, an application program according to Ir. Saiful B. Ridwan grouped into 4 based on intent, namely :
                                            Edutainment ( education )
     Designed specifically for the purpose of education or teaching with elements of entertainment ( entertainment ) in accordance with the material. These programs are generally taught the basic knowledge such as reading, math, history, geography, and so on. For example, an application entitled " Beginning Reading " ( to read ) ; " Millies 's Math House " , " Let's Learn Plus Minus " ( count ), " Where in the World is Carmen Sandiego " ( geography ), or " The Cregon Trail " ( history ).
                                            Games ( Games )
     Designed for the purpose of the game and not specifically given payload containing a particular aspect. While there are usually additional knowledge gained as a side effect only. This game is usually most in demand by children and adults. Applications can be grouped into types of games adventures ( adventures to achieve specific goals with a variety of challenges ), arcade ( game face fast-moving objects, " harm ", or " attacking " player ), role play ( such adventures but players come to be one of the characters ), simulation ( simulation games without a specific purpose and what you want to do left to the player ), and strategy ( such as a simulation game with a clear goal that requires the player's strategy ).
                                            Infotainment ( Information )
     Meanwhile infotainment, designed for the purpose of reference or submission of complete information about a particular topic. For example, " Grolier Multimedia Encyclopedia " and " Encrata '95 ".
                                            Interactive Movie ( Entertainment )
     While interactive movie is designed for entertainment purposes. The program is designed for interactive movie entertainment only and lacked educational value.
Of the several types of computer application programs are expected to teachers or parents can choose appropriate computer programs for students that can be used in learning.

2.6 Role of Computers in Learning
In every learning is commonly used instructional media or means of learning technologies. It is based on behaviorism is the view that learning occurs as a result of teaching presented by the teacher through or with the help of the media. However, in view of constructivism, the media is used as something that gives the possibility of students actively construct knowledge. Within the framework of constructivism, learning is seen as an activity students manage cognitive resources to create new knowledge by extracting information from the environment and integrate it with the information that has been stored knowledge dibenaknya. ( Krismanto, 2003:4 ).
Researchers have found that there are a variety of easy ways students process information. Most easy to process visual information, others prefer to feel happy or easier when there is sound, and others will be easier to understand if the use of written information.
The computer is one medium that can transform the various symbols in the information from one form to another form. Students can type text, and sophisticated computer can mentranformasikannya into other forms, such as pictures and even sound. Computers can transform numbers into the form of a graph or curve.
Computer as an interactive means of learning is one form of programmed based on the Law of Effect. In Law of the main assumptions that are believed to result of behavior that is followed by a sense of fun to do or are likely to be repeated than behavior that is not liked. ( Krismanto, 2003:6 ).
Based on the result of this law comes SR theory ( which includes stimulus, response and reinforcement). Learning with this theory is done by the students were given questions as a stimulus, then he gave an answer ( response ) of a given question. Furthermore, the student responses taken by the computer and if the answer is correct computers provide reinforcement (reinforcement ). If any other questions that computers provide load impetus to improve students' answers. ( Krismanto, 2003:6 ).
Feedback in the form of reinforcement is a form of motivation for students. Without feedback the students do not know the truth of their answers, do not know how far their success.
The computer is a tool that can be used as the main medium of learning for its wide range of capabilities, including having a virtual quick response ( view) of the input given student ( user ), has the capacity to store and manipulate information, and can be widely used as a tool in the learning activities. In addition, another computer that has the ability to control and organize a wide variety of media and instructional materials such as films, videos, slides, and information that can be printed.
Roestiyah ( 2001 ) explains that, in theory, have the computer skills that force more than a teacher, because the computer can :
a.    Saving some information.
b.    Choosing such information with high speed.
c.    Presenting the students with a challenging diagram signs.
d.    Type answer the needs of students.
e.    Provide feedback to individual students as soon as possible.
f.     Provide information to the difference with different students.
Privileged use of computers in the learning process ( Muhammad Ikhsan, 2006 ) :
a.    Computers can be taught individually ( individualization of the learning process ) speed can be adjusted to the students' abilities, methods or learning strategy that is more appropriate, adjustments to the content of the material and the level of difficulty.
b.    Can be used at any time ( unlimited time ) and can be used anywhere ( not limited spaces ).
c.    Eliminate fear and shame.
The computer can be programmed to be used in the teaching potential in three ways, namely :
a.    Tutorial
     In this case the program requires the computer to act as a tutor who led the students through a sequence of material that they expect to be a staple understanding. The computer can find the scope of difficulty for each student, and then explain the opinions found students, using appropriate examples and exercises and test the students at each step to check how well students have understood.
b.    Simulation
     The second form is for teaching with computer simulations on a particular state, or a system in which students can interact. Students can refer to the information, so as to arrive at the answer, because they think healthy, try out its interpretation of the principles that have been determined. The computer will tell the student whether the impact of the decision, mainly about the reaction of criticism or opinion.
c.    Data processing
     Rowntree ( Roestiyah , 2001 ) wrote that in this case the computer is used as a research extensive amount of data or manipulate data at high speeds. Students can ask the computer to examine certain figures, or generate graphics and images that are difficult or complex.


Use of Computers in Learning Activity :
a.    For Cognitive Objectives
     Computers can teach the concepts of rules, principles, steps, processes, and complex calculations. Computers also can explain the concept simply by merging visual and audio animated .
b.    For Psychomotor Objectives
     With this form of learning that is packaged in the form of games and simulations are used to create a very good workplace conditions. Some examples include programs aircraft landing simulation, simulation of war in the most severe terrain and so on.
c.    For Affective Objectives
     When a program is designed precisely to give a piece of audio or video clips that it inspires feelings, learning attitudes or affective can be done using computer media.
The computer as a medium of learning has its advantages and disadvantages ( Benny A. Pribadi and Tita Rosita, 2002:11-12 ) :
                    Advantages of Computers
Heinich et al. (1986 ) suggested a number of strengths and also weaknesses in the computer medium. Computer applications as learning tools provide several advantages. Computer :
a.    Allows students to learn according to their ability and speed in understanding the knowledge and the information displayed.
b.    Enables students to take control of their learning activities.
c.    The use of computers in distance education institutions to provide flexibility to the students to determine the speed of learning and choose a sequence of learning activities according to the needs.
d.    Computers can create an effective learning climate for students who are slow ( slow learner ), but also can boost the effectiveness of learning for students more quickly ( fast learner ).
e.    The computer can be programmed to be able to provide feedback on learning outcomes and provide confirmation (reinforcement ) on student achievement.
f.     Computers can also be used as a means for learning the individual ( individual learning ).
g.    Excess another computer is the ability to integrate the components of color, music and animated graphics ( graphic animation ). This causes the computer to be able to convey information and knowledge with a high degree of realism.
h.    Another advantage of the use of computers in the process of learning can improve learning outcomes with the use of time and cost is relatively small.

                    Disadvantages of Computers
Furthermore Benny and Tita ( 2000) provide an explanation. Besides having a number of advantages, the computer as a means of interactive communication also has some disadvantages, namely :
a.    The high cost of procuring and developing computer programs, especially those designed specifically for the purpose of learning.
b.    Procurement, maintenance, and treatment includes computer hardware ( hardware ) and software ( software ) requires a relatively high cost. Therefore, consideration of costs and benefits ( cost benefit analysis ) needs to be done before deciding to use the computer for educational purposes.
c.    Another problem is compatability and incompability between hardware and software. The use of a computer program usually requires hardware with the appropriate specifications. A computer software often can not be used on computers that are not the same specifications.
d.    Designing and producing computer-based learning programs (computer based instruction) is not an easy job. Producing computer program is an intensive activity that requires a lot of time and special skills.

The advantage of learning using computer media ( Krismanto, 2003: 8 ) include :
a.    Computer-assisted learning if designed properly, an effective learning medium, can facilitate and improve the quality of learning.
b.    Increase students' motivation.
c.    Appropriate supports individual learning abilities of students.
Can be used as a transmitter of direct feedback.
d.    The material can be repeated as needed, without causing boredom.
While the limitations of learning using computer media ( Krismanto , 2003: 8 ) is :
a.    Limitations form of dialogue or communication.
b.    Frequent computer use can lead to dependence which result in less good.
c.    Reduce social interaction attitudes should be an important part of education.
The limitations of computer media by Arsyad (2002 ) are :
a.    Although the price of computer hardware tends to be decreased ( low ), the software development is still relatively expensive.
b.    To use the computers required specific knowledge and skills on the computer.
c.    The diversity of computer models ( computer software ) often cause programs ( software ) are available for one model does not fit with the other models.
d.    Programs are available at this time does not include students creativity.
e.    The computer is only effective when used by one person or a few people in a small group.





CHAPTER III
METHODOLOGY


3.1 Data Collection
"Data collection techniques is an effective way to capture accurate data"     ( Suharsini, 1993: 192 ). Data collection techniques in this study are interviews conducted by the author on the speaker in school and in the environment where the author lived. Interviews used is guided interviews, which were conducted by questioning respondents using an interview guide                        ( questionnaire that was read ) is a collection of questions to be asked of the respondents.  In addition to the interviews, the authors also look for some references on the internet for data collection.
 Based on interviews and references of the internet on data collection, the authors can conclude any answers from the interviewees about the role of computers in learning.

3.2 Data Analysis
Data analysis is the effort made by means of analyzing or examining the data, organizing data, select and sort them into something that can be processed, search and find critical patterns based on the needs in research and decide what can be published. Step analysis of the data will go through several steps: data collection, classify, select and sort the data and then analyze it. Analysis of these data in the form of a narrative of a series of research results to answer the problem formulation and deduce the answers from the interviews in data collection.




CHAPTER IV
FINDINGS


Interview is one of the primary means of data collection used in this study. The interview is expected to reveal the perception of respondents regarding the variables studied. Measurement indicators set out by him in the form of the interview must have the ability to measure the variables. The ability to measure the indicator variable called test validity (validity grain).
Based on interviews conducted by the author on 11 speakers on "The Role of Computers in Learning", one of the 11 interviewees said that the role of computers in learning is very important because computers facilitate human learning. Meanwhile, 10 other speakers argued that the computer is important for the same reasons that the computer as a means to facilitate human access information, process data, and streamline the learning process.














CHAPTER V
CONCLUSION



Based on the discussion and the interview can be summed computer is an electronic device that can receive data input and process data, provide information using a program stored in memory (stored program) so that it can store the programs and the results of the processing work automatically.
 The role of computers in learning is very important, because the computer is a tool that can be used as the main medium of learning with its wide range of capabilities, including having a virtual quick response (view) of the input given student (user), has the capacity to store and manipulating information, and can be widely used as a tool in the learning activities.
 In the computer study has advantages and disadvantages. Where one of the advantages that computers can provide the motivation for students to learn in the presence of a variation, and shortcomings that reduce students social interaction.
