CHAPTER I

INTRODUCTION

A. Background

Technology always develop every time, technology helps us to do

everything, even in education. Technology today can influence education

system, the way of teaching and how student get the information.Using

technology hopefully can make every student has a change to get proper

education.Thecurrent generation of students, commonly referred to as “NetGen” learners, grew up surrounded bytechnology and bombarded by

continuous technological advancements. Computers, multimedia, theInternet,

cell phones, and computer games were and continue to be a central and

intuitive part of theirlife (Pergola and Walters). That situation not happen in all

school, some school have not use technology in their learning process. In

Indonesia, only some school that has been integrated between learning process

at school and technology that using internet.

The development of multimedia technology has changed the way people

learn, obtain various information as well as in interpreting information (Ziden

and Rahman, 2013). The use of the interactive learning environment begins

with an instructor uploading a set of lecture slides and setting up an interactive

learning session. This task may include adding quiz questions and the lecture

session preferences prior to entering the classroom. The instructor has an

expanded user interface that provides access to these administrative functions

such as uploading slideshows, creating quizzes, and enabling or disabling

interactive features (Chao, Parker and Fontana, 2011). Student can access the

materials or information every time and everywhere as long as there is an

internet. This is a good idea if we develop this concept into Indonesia

education system because children in Indonesia can access the materials

Universitas Pendidikan Indonesia | repository.upi.edu | perpustakaan.upi.edu

In learning science concept, sometimes the student find difficulty in

learning. By using this web-based learning, the student can choose the time for

learn and they can use their own gadget to access the materials. Web-based

learning also can increase the student motivation in learning. Today, some

student lazy to learn because the traditional method that use is not match with

the development of technology.

In this research the authors try to find out the effect of Edmodo towards

student cognitive and motivation while learning thermal physic.Edmodois an

educational technology that teacher, student and parent can use. By this

application, teacher can share information, materials of teaching, task for the

student, and also exam.

Teacher can track student performance and give score to the student. The

student can access the materials every time, chat with their friends and doing

online quiz.This research will try to measure student students’ cognitive that is

measured in this research involves level cognitive, understanding (C2),

applying (C3) and analysing (C4) based on Taxonomy Bloom (Anderson et

al., 2001).

To teach thermal physic,Edmodo can be used as an additional media,

teacher can put all materials on the Edmodo and the student can access it

before start the class or at home. In this topic teacher will do some classroom

activity and quiz. There are some sources that teacher will put in Edmodo,

there are video, articles, question and quiz. Teacher will ask the student to

access Edmodo before come to classroom. Student can easily access the

source of the lesson and can repeat it every time student need. There are

several advantages if teacher use Edmodo than the other media, Edmodo is

easy to use for teacher and student, teacher can put note, quiz, polling, alert

and student can access it everytime. By using Edmodo, the student can

improve their motivation in learning, while the motivation increase, the

H1 : There is difference of students cognitive and students’ motivation in

learning thermal physic using Edmodo as Web-Based Learning.

E. OperationalDefinition

In order to avoid the misconception in this research. Some operational

definitions are explained in this research. Those terminologies are explained as

follow:

1. Learning activities using Web-Bases Learning conducted by using Edmodo.

2. Cognitive level in this research is competence of students that covers the

level cognitive such as understanding (C2), applying (C3) andanalysing (C4),

based on Taxonomy Bloom (Anderson et al., 2001). This competence is

measured by using multiple choice questions (pre-test and post-test).

3. Students’ motivation in this research is referring to ARCS model by Keller.

ARCS model consist of attention, relevance, confidence, satisfaction. Data

obtained through questionnaire that is adjusted with ARCS model.

F. Research instrument

In this research, instrument is necessary to be used for gaining data.

There are two types instrument that are used in this research. Those instruments

are described below.

1. Objective test

No Condition

G. Instrument Development

The objective test in form of multiple choices will be analyzing using

ANATES 4.9.0 statistical software. All of the test items after analyzed and

judged by the expert will be tested to the students. The result of the test items

after tested will be used, revised or deleted.

There are some aspects that must be analyzed while making the objective

test, there are:

1. Validity

To get valid result of the activity, the instrument that will be used must

Pia Fildzah Vania, 2015

THE EFFECT OF EDMODO AS WEB BASSED LEARNING TOWARDS STUDENT COGNITIVE AND MOTIVATION IN LEARNING THERMAL PHYSICS

Universitas Pendidikan Indonesia | repository.upi.edu | perpustakaan.upi.edu

validity. Content validity has a relation with the instrument, the content or

materials will be put in the content validity. To determine the number of

validity, it is done with the product moment correlation equation as follows.

� = −

2− 2 2− 2

Where,

rxy = coefficientcorrelation or item validity

ƩX = sum of total score of all students for each question item ƩY = sum of total score of all students for whole test

N = total number of students

X = score of each student for each question item

Y = total score of each student

The validity interpretation is represented in the table below.

Reliability is a measurement which stated about consistence of the

measurement tools that used. (Arikunto, 2013) states that the reliability

tends to a definition about trust instrument which is used as collecting data

tools.

To define the reliability of objective test, alpha formula will be used as

a formula because the question using multiple question.

Where,

r11 : Instrument reliability

n : Amount of question

Universitas Pendidikan Indonesia | repository.upi.edu | perpustakaan.upi.edu 3. Difficulty Level

Level of difficulty here means level of difficulty of the student’s but not from teacher perspective, the good question are the question that is not to

hard for the student but also not too easy to be answered.

To show the difficulty level of the question, difficulty index can be

used to show the difficulty level of question. The range of level of difficulty

is from 0,00 to 1,00. The lower the index, then the more difficult the

question and vice versa.

To find out the difficulty index the formula that is used is shown below:

JS B P

Where,

P : Difficulty index

B : Number of students who answer the question correctly

JS : Number of all students who join the test

The classification of difficulty level is represented in the table

below.

Table 3.5 Interpretation of Difficulty Level

No. Difficulty Value Criteria

1 0.00 – 0.30 Difficult

2 0.30 – 0.70 Medium

Universitas Pendidikan Indonesia | repository.upi.edu | perpustakaan.upi.edu 4. Discriminating Power

Discriminating power means an ability of question to discriminate

between high-achiever students and low-achiever students (Arikunto, 2013).

The question that can be answered both from high-achiever and the

low-achiever student is not good question because it is too easy to answer.

Otherwise, the question that cannot be answered both of them is also not good

question because it is too hard for the student. Number that shows

discriminating power is called as discriminant index (D). Discriminant index

range is about 0,00 to 1,00. Good questions will have discriminant index

between 0,4 and 0,7 (Arikunto, 2013).

The formula of discriminant index is

B

D : Discriminating Power (Discriminant Index)

A

B : Number of high-achiever students which answer the question correctly

B

B : Number of low-achiever students which answer the question correctly

A

J : Total of students in upper group

B

J : Total of students in lower group

A

P : Proportion of upper group who answer question correctly

B

P : Proportion of lower group who answer question correctly

P is level difficulty

To determine whether the discrimination index is a good or not, it can be

is not good distractor. A good distractor at least chosen by 5% of the student

that joined the test (Arikunto, 2013).

6. Recap Result

Before using objective test in the class, the objective test should be tested

in form of validation, reliability, distraction level, discriminator power and

distractor. The test using ANATEST, the recapitulation of test presented on

that cannot use Edmodo, test item given in paper test. Each number that

correct given by 5 point and if wrong 0 point. Question that given in

posttest same question with pretest and conducted using paper test.

b. Calculation of gain score and normalized gain

The result of score test item will be processed using SPSS 20.0 to

find gain score and normalized gain score. Gain score is the gap between

pretest and posttest while normalized gain used to find the improvement

categorize. According to Hake, here this the formulas:

� =� − ��

Description:

G: Gain Score

Sf: Average Post-test Score

Si: Average Pre-test

The calculation of gain score used to see whether the Edmodo give

a significant positive impact or not. Normalized gain calculation used to

find and the improvement of Edmodo. Normalized gain of each student

(g) determines by followings this formula:

= �

� � =

� − �� �� �� � − �� Description:

<g> : Normalized Gain

c. Normality test

Parametric assume that each variable in this research has a normal

distribution. Normality test use to see whether the data has normal

distribution or not. This research using SPSS 20.0 to test normality,

Kolmogorov-smirnov with significant level (α) is 0.05. when significant

value of Kolmogorov-smirnov>0.05 H0 will accepted and when value

<0,05 H0 will rejected the hypothesis like shown below.

H0 : Sample comes from population that has normal distribution.

H1 : Sample comes from population that has not normal distribution.

d. Wilcoxon test

Wilcoxon test chosen because the number of sample that used less

than 30 samples. This test used to compare two groups that related each

other. H0 rejected if significant p-value < 0.05 with hypothesis:

H0: There is no difference of students cognitive and students’ motivation

in learning thermal physic using Edmodo as Web-Based Learning.
