CHAPTER I
INTRODUCTION
1.1. Background
International Networking (Internet) users are forecast to exceed 100 million
in Indonesia (Desnet, 2015). These are very fantastic numbers. Most user are
among students, employees, businessmen, even housewives with at the level of
the age that is accessed through gadgets such as mobile phones and notebook
(Antaranews, 2014). Most internet users are dominated by teens aged 15-19
expressed by the research of Taylor (Kompas, 2015). Internet was accessed in
anywhere, anytime, and any way. Those were facilitated in educational
institutions, offices, recreation, shopping, and even cafe which are free. This
phenomenon is the effect of the technological developments that make it as
lifestyle, business, interact, socialize, learn, and get information.
Internet is often described as the basis of the ―
information super highway‖,
which is being discussed at different levels in nearly all the media (Redl et all,
1996). Internet has also become a major reference for accessing news and
information that is massive in various sectors of life. Even pens and paper for
students has turned into Facebook, Twitter, Line, Whats Up, Instagram, YouTube,
Google, Wikipedia, and others. Internet users are most teenagers are still at the
age of junior high and high school that so ambitious in seeking information and
accessing information through the Internet. Djoko Agung Harijadi as a
commissioner technology information said that there are three main motivations

2

Internet use by children and adolescents, seeking information, friendship and
entertainment (Kominfo, 2015). Based Survey that most teenagers use internet as
e-mail (59%), instant messaging (59%) and social networking (58%). In addition,
they also frequently use a search engine (56%), access online news (47%),
blogging (36%) and play online games (35%). It gives a serious influence. This
influence is evidenced in a study conducted by Aryn Karpinski of researchers
from Ohio State University, showed that students' learning time taken by
immersion in a social media site that is particularly popular among FB
(Facebook). They said that their study time has been consumed. The average
student FB users lose time between 1-5 hours to 11-15 hours of study time per
week to play FB (Ridhota, 2013).
The development of information technology and system-based online can
be effective and efficient ways to use as a learning for students. These are gives
most benefits for learning. A variety of diverse emerging computer-based
learning, include computer based learning (CBL), online learning or Web Based
Learning, E-learning, Distance learning, and etc. So, most of educator discuss
about ―
online education‖. Steve Mccarty explain that : ―
Online education‖ also
refers to learning methods that at least partly utilize the information and
communication technologies (ICTs) available through the internet. Given the
explosive growth of specialized knowledge and paradigm shifts in educational
approaches, lifelong education is needed above all by educators themselves. For
online educators not to replicate the classroom but to take advantage of new
media, new ways to communicate, and to design educational experiences,

3

renewed professional development for educators in virtually all fields of enquiry
is also necessary. Educators are thus utilizing the internet for professional
networking regionally and globally to learn from one another about the new media
and their applications to education (Mccarty, 2006).
As an important pedagogical component in teaching and learning
dynamics, classroom assessment in web-based learning environment can be
practiced to reflect the shift. Technology has provided opportunities for online
assessment to be more Student Centered Learning (CTL) to promote self-directed
learning, and to increase learner autonomy. Practicing ―
assessment for learning‖
can cultivate student ownership, and will impact effort and achievement
eventually (Xin and Kim , 2004).
In government regulation, number 13 in 2015 on the Standard Assessment
of education in primary and secondary education consist of: 1) assessment of
learning outcomes by educators; 2) assessment of learning outcomes by
educational units; and 3) assessment of learning outcomes by the Government
(kemendikbud, 2015). Assessment of learning outcomes by educators is the
important and continuous with the final round of assessment by the education unit
and the government. Therefore, the accuracy of methods in assessment of learning
outcomes, indicators used, and the type or the tool has a major role in determining
the success of the assessment.
Programmed for International Study Assessment (PISA) ranked Indonesia
as one of the countries with the lowest ranking in the achievement of quality
education in 2012 especially in science (Tempo, 2013). There are some factors

4

that is suspected to be the cause of the lack of science. Among of the science is
chemistry. There are many reasons for students finding chemistry difficult to
learn. The number one reason why students fail chemistry is that they do not work
enough problems. Teacher-related factors and school environment such as
attitude, time, remuneration, laboratory adequacy and others, exert remarkable
influence on students’ positive achievement in chemistry (Silberman, 1981).
Formative assessment can play a powerful role in the learning experience,
moving an average student, for instance, to the top third of the class – but only if
certain conditions are satisfied. Student tasks needed to be aligned, or on target,
with learning goals, and students need to receive meaningful and timely feedback
on their performance, as well as targeted follow-up work (Wilson and Kathleen,
2006). Outcome of any formative assessment should be one that ultimately helps
improve learning, it has been suggested that there should be focus on three
specific drivers when designing any formative assessment: using a method to
inform students of gaps in their learning; familiarizing students with the
expectations of summative assessments; and providing feedback that guides the
direction of student. Such lower-stakes formative assessments establish a more
comfortable learning environment and increase students’ potential for success on
the summative final (Cherem, 2011). Students should also be educated about the
use of formative assessment to help them to take advantage of the opportunities
brought by formative assessment before its utilization (Yalaki and Bayram, 2015).

5

Homework, or a homework assignment, is a set of tasks assigned
to students by their teachers to be completed outside the class. Wilson, Jan, and
John Rhodes explain that :―
Homework is very important to improve students
learning and skill. But Teachers are finding that a number of students do not
complete homework assignments for various reasons, and have long experienced
the frustration of students who do not or will not complete their homework
assignments. Based on the research of Wilson and John Rhodes that Not
surprisingly, 73% of the freshmen agreed that they do not like homework, 84%
thought it was boring, and 87% felt that teachers assigned too much each night
(Jan and John, 2010).
Whereas, homework have the relationship to student’s achievement,
reinforce what they learn, prepare for complex lesson, and give the opportunity to
parents about children’s education. Understand about the subject learning need
more assignment by homework frequently repeated. Rose explained that the
lessons learned today will be forgotten as much as 70% within 24 hours if you do
not do a special effort to remember it means that lessons must be frequently
repeated (Rose and Malcolm, 2002). Then, research that done by Bayram and Arif
displayed a positive correlation between chemistry achievement of the students in
the first group and their science teaching attitude, and logical thinking ability. 78.4
% of the variance of chemistry achievement is explained by students’ science
teaching attitude, and logical thinking ability when doing their homework
(Bayram and Arif, 2009).

6

In traditional assessment was occurred in error measurement and the
person doing the assessment. Errors in measuring tool assessment can be
improved by developing good formative tests through the analysis of item test
which is used References Assessment Criteria (PAK) to obtain valid and reliable
test. Errors in giving the assessment are influenced by subjectivity and error to
give the assessment results. This can be corrected with a program-based
assessment as well as multimedia website that can automatically process and
calculates a score student learning outcomes (Arikunto, 2001). In addition, the
problem is in the learning process is limited to a specified time schedule and just
being in a classroom. For a long time, the main approach for teaching and learning
was mainly the didactic traditional approach, which depends on memorization
where teachers are the main source of information, and students are only passive
receivers (Indra, 2013).
Educator must create and design homework to be more attractive to doing
homework. Using of online assignments benefits the students’ success more than
offline, non-graded homework. Educators increasingly recognize that students
must learn how to develop and apply knowledge creatively, not simply remember
what they have been told. This goal requires shifting from traditional lessons
based on transmitting information toward approaches that help learners build
robust and flexible understanding. New technologies appear to hold promise in
overcoming the traditional limitations of professional development. The World
Wide Web, with its rich trove of multimedia resources, interactive tools, and
telecommunication facilities, accessible from anywhere on the planet, seems full

7

of potential as a facilitator of teacher learning (Martha et all, 2001)
Eichler and Junelyn (2013) said that The use of online computer based
systems also provides the opportunity to create ―
smart‖ homework systems that
can respond individually to students in a way not possible with handwritten
instructor graded homework, particularly for large enrollment courses where
providing individualized feedback might be logistically unfeasible. Based on this
research that using online homework systems helps prepare them for the firstquarter general chemistry course, and subsequently improves student performance
on the final exam.
Interactive technologies provide multiple advantages and benefits for
online instructors and learners. These include of more efficient management,
collection, and transfer of assessment information; The ability to track, monitor
and document students’ activities automatically; Multiple communication tools to
facilitate and document dialogues that can be revisited as part of the learning and
assessment process; More opportunities and ways for providing feedback to
students; Vast libraries of resources and interpretive tools; Increased student
participation in discussions (i.e., more students can participate in online
asynchronous threaded discussions than in face-to-face classrooms); An increased
emphasis on student thoughts and reflections as students learn to express their
ideas in writing; More precise grading of student participation in the course
content (process) because their discussions are captured in print (Comeaux, 2006).
Edmodo is an educational technology company offering communication,
collaboration, and coaching tools to K-12 schools and teachers. The Edmodo

8

network enables teachers to share content, distribute quizzes, assignments, and
manage communication with students, colleagues, and parents (Wikipediac, 2015).
As co-founder of Edmodo, Nic Borg provides teachers and students a secure
social network for classroom use. Edmodo provides classrooms a safe and easy
way to connect and collaborate, offering a real-time platform to exchange ideas,
share content, and access homework, grades and school notices (Ziolkowski,
2011). The collaborative environment provided by Edmodo ensures that
knowledge is no longer contained in places defined by geography and can be
shared and viewed transparently (Al-Kathiri, 2014). In Edmodo, Teachers can
create their own questions and select correct answers by using Qui and interactive
online assessment tool that is automatically graded through Edmodo. (Faison et
all, 2012).
Schools and companies are using similar technologies to address similar
problems because there is ample evidence that appropriate use of technology can
boost retention rates, reduce boredom and misbehavior, and, in many cases, cut
costs. Numerous studies have found that educational technology clearly boosts
student achievement, improves student attitudes and self-concept, and enhances
the quality of student–teacher relationships (Lagowski, 1998). Using web-based
activities contributes significantly to students’ understanding (Frailich et all,
2007).
Based on description above it is necessary to do an research in the
preparation of interactive assessment by using online system. So the researcher

9

establish the tittle : “The Effectiveness of Edmodo Website as a Media to Improve
Student’s Achievement and Motivation on Learning Acid Base ”.
1.2. Problem Identification

theoretical, empirical, and practical applications for future research. Suggestions
for four distinct stakeholders would be explained below:
1. For students,
Teachers take the time at the beginning of the year and train students about
proper website edmodo etiquette. Thus students become proficient in running
edmodo so focus on the work test online instead distraction in its use. Teachers
need to specify exactly how students should appropriately answer in edmodo, and
how to communicate interactive via edmodo when ask the homework to help
each other in a social constructivist setting to increase their knowledge about the
content area. So students will know using of edmodo properly.
2. For teacher or Future Researcher
Similar to the students, it is highly recommended that the teachers take part in
professional development of how to utilize and implement Edmodo in the
classroom before expecting them to immediately begin using it. That can engage
students actively in learning and being able to motivate students to learn. The
timing in the time period over which long made the teacher / instructor and
students become more proficient in the use of media website Edmodo. Neither are
the constraints in terms of language or the mechanism in practice.
It is therefore expected for future studies, researchers only as instructor and
observer in this study. Students are more enthusiastic and serious if the chemistry
teacher. Teacher must be design the Instrument for homework and

online formative expected in the form of the essay. This was felt would improve
students' critical thinking.
3. For Central Office Personnel
Edmodo does not have any fees attached in order to access and use the
service. With cost a major factor for many school districts, this is a very
important advantage of using Edmodo. However, because it is based on the
Internet, it is important that schools have the proper bandwidths in order for
the program to run smoothly. Therefore very important for schools to have
enough bandwidth for the program to succeed.
In addition, Edmodo itself may be a free Internet service, but the
hardware that must be used in order to access it can of course become a large
ticket item for each classroom. Thirty computers or tablets for one classroom
could incur a cost of several thousand dollars.
4. Programmer
Researchers hope the picture display on the smartphone to be a better and
clear. The image or text quality of phone influences to students achievement.
Students could not see the image or text clearly. If the displayed image is good
then will be easier for students to work on the problems in the media socrative
so that the learning process to be effective and efficient.
