Improving Students’ Self-directed Learning Outcomes on Mechanics Subject by Using E-Learning

Technology development in globalization era is growing so fast. All sectors, including education, were demanded to be integrated with technology in order to produce competitive human resources (Kompas, 2012). Meanwhile, the development of information and communication technology in education has triggered a shift from face to face conventional learning to e-learning which can be accessed from any computers with no limitations. Along with the effects of globalization, education will be more open and two way, diverse, multi discipliner and related to competitive productivity (Kompas, 2014). Learning outcomes are the abilities of the students after they received a learning experience (Serevina, 2017).


Introduction
Technology development in globalization era is growing so fast.All sectors, including education, were demanded to be integrated with technology in order to produce competitive human resources (Kompas, 2012).Meanwhile, the development of information and communication technology in education has triggered a shift from face to face conventional learning to e-learning which can be accessed from any computers with no limitations.Along with the effects of globalization, education will be more open and two way, diverse, multi discipliner and related to competitive productivity (Kompas, 2014).Learning outcomes are the abilities of the students after they received a learning experience (Serevina, 2017).
In Antara News.com with the topic Indonesia X and UNPAD release free online course explained that Indonesia X with State University of Padjadjaran (UNPAD) provide Massive Open Online Courses (MOOC) which gives free online courses access for everyone in all over Indonesia.Free online courses in indonesiax.co.id aims to democratize education in Indonesia so that everyone, everywhere in Indonesia can be attended (Antara News, 2016).
Previous research by Maha Bali (Maha Bali, 2015) stated that cMOOCs gives the opportunity to its participant to create a good collaboration which can help them to practice and develop skill in digital era.cMOOCs can survive because of participant transformation to build connection between participants.Whereas, this research will focus on cMOOCs web based multimedia development and limited to basic mechanics subject.
Meanwhile, in research about cMOOCS And Global Learning: An Authentic Alternative (Carol Yeager, 2014) explained that cMOOCs can be used as a media to explore and to develop knowledge, skill, and individual behavior through provided contents and also can be used as place to build connection through discussion forum.
In a research study by Kristina (Kristina, 2014) concluded that students participation in cMOOCs based e-learning encouraged students to develop their selfabilities and improved their motivation.cMOOCs also demands students to be more active in their activities and collaborating with other participants in order to achieve their goals.
Observation results also showed that Open University in Indonesia has provided several certified online course materials in moocs.ut.ac.id.Those materials are the introduction to moodle 2.9, parenting, and marketing management.Basic mechanics has not been available in the following web.So the topic in this research choose mechanics subject.
The result of questionnaire through Google form which was given to 64 respondents from universities in Indonesia was 57.1% stated that their lecturers have already used online instructional media, while 52.45% have not yet.Those online instructional media were website which provide PDF file, while video or animation were not provided in those website.Discussion forum and certificate of graduation have not provided in those website either.However, there were exercise questions to evaluate students learning outcomes.About 82,8% of respondents also stated that cMOOCs web has not already used as instructional media in their respective universities and 93.8% stated that the development of cMOOCs web based instructional media was necessary.Respondents were used to use gadget such as laptop or personal computer to access the information with the internet and 92.2% agreed that the instructional media can encourage them to do a self-directed learning.
Based on argumentations above, this research is about Improving Students' Selfdirected Learning Outcomes on Mechanics Subject by Using E-Learning was done.Instruments used in this research were mechanics multiple choice questions which consists of oscillation, mechanical wave, thermodynamics and students' selfdirected learning questionnaire.Questions were validated using point biserial formula and KR 20/21 to calculate its reliability (Widiyanto, 2014).Questions were used to find if there was an improvement of students' self-directed learning outcomes.

Research Method
Questionnaire was used to rate students' initiative, self-efforts, and responsibility.

Data collection
Data collection was done by taking secondary data, interview data and event data as follows:  Reliability test used KR-20/21 formula.The results of reliability test were: 0.91 for mechanics questions, 0.91 for oscillation and mechanical wave questions, and 0.95 for thermodynamics questions.Those results were interpreted as a very high category.

Reduction of data
According to Widiyanto, instruments were considered to have a high reliability if its reliability coefficient is between 0.8-1.0(Widiyanto, 2014).At significance level of 5% for 31 respondents, r table was obtained by 0.355 (Sugiyono, 2015).
According to calculation instruments used for data collection were valid and reliable.

Verification
Verification was done by analyzing pretest and posttest results.Data verification was done in two ways, by data triangulation and N-gain test.N-gain is the difference between posttest result and pretest result.N-gain indicated students' improvements after learning is done (Hake, 1999).
Spost is posttest score, Spre is pretest score and Smax is maximum score of test.N-gain classifications are: (1) if g ≥ 0,7, N-gain is in high category; (2) if 0,7 > g≥ 0,3, N-gain is in good category; and (3) if g < 0,3 N-gain is in low category.According to the calculation from 31 students who followed mechanics subject lecture, obtained N-gain = 0.818 and considered to be in high category.Pretest and posttest result of students indicated that there was an improvement of students self-directed learning from Elearning usage.

No
Then, the questionnaire was also used to find students initiative, self-efforts and responsibility.Questionnaire referred to Likert scale interval.Likert scale is used to measure behavior, opinion, and perception about social issue or phenomena (Riduwan, 2007).Obtained data then interpreted as follows:  The Questionnaire's result is shown in figure 6.

Conclusion
According to assesment result of elearning's effectivity, obtained N-gain= 0,818 (high category).This result indicated the improvement of students' self-directed learning outcomes.Questionnaire showed students' initiative score by 85%, self-effort by 88% and responsibility by 97%.So, it can be concluded that there was an improvement of the students' self-directed learning outcomes in the mechanics subject using E-learning.
