Science process skills are one of the indicators to know the level of achievement of physics teaching goals. This research examines the influence of guided inquiry models through virtual laboratories on students' science process skills. The research was a quasi-experiment conducted at the senior high school in Mataram, Lombok. The samples were class XI students, as many as 58 people divided into two sample groups: experimental and control groups. The guided inquiry model through the virtual laboratory was applied to the experimental group and the conventional model for the control group. The instrument used was a performance sheet. A t-test was used to analyze the effect of learning model on science process skill. The results of this study found that the achievement of science process skills for the experimental group was higher than the control group. The guided inquiry models through virtual laboratory have a significant effect on science process skills, especially on skills: hypothesizing, practicing, and communicating. These findings contribute significantly to the current knowledge about the effectiveness of guided inquiry models through virtual laboratories to improve students' science process skills in physics teaching.

Karakteristik fisika tersebut diharapkan dapat dimanfaatkan untuk membiasakan dan mengembangkan keterampilan berpikir dasar siswa menuju pada keterampilan berpikir tingkat tinggi. Keterampilan berpikir tingkat tinggi merupakan suatu keterampilan berpikir yang tidak hanya membutuhkan keterampilan mengingat saja, namun membutuhkan keterampilan lain yang lebih tinggi, seperti keterampilan berpikir kritis. Keterampilan berpikir kritis secara esensial merupakan keterampilan menyelsaikan masalah (problem solving). Menurut Paul dan Elder (2007), berpikir kritis merupakan cara bagi seseorang untuk meningkatkan kualitas dari hasil pemikiran menggunakan teknik sistemasi cara berpikir dan menghasilkan daya pikir intelektual dalam ide-ide yang digagas.Model pembelajaran fisika yang dikembangkan oleh kebanyakan guru sering tidak menyiapkan siswa untuk terlibat dalam upaya penggunaan dan pengembangan pola berpikir dasar menuju pada pola berpikir tingkat tinggi. Penguasaan konsep dan keterampilan berpikir kritis siswa terhadap konsepkonsep fisika sebagai indikator keberhasilan suatu proses belajar mengajar dari berbagai penelitian secara umum masih kurang.Kurangnya penguasaan konsep-konsep fisika dan keterampilan berpikir kritis salah satunya disebabkan karena siswa tidak banyak dilibatkan dalam proses pengkonstruksian suatu konsep dalam pikirannya. Untuk dapat mengembangkan pengusaan konsep dan keterampilan berpikir kritis pada pembelajaran konsep-konsep fisika yang bersifat abstrak perlu bantuan teknologi informasi. Teknologi informasi dalam pendidikan diaplikasikan dalam bentuk multimedia interaktif berupa perangkat lunak (software), yang memberikan fasilitas kepada siswa untuk mempelajari...

Abstract-This research aims to know the effect of using virtual laboratorial towards concept mastery and creative thinking ability of students on the material of vibrations and waves. This research is an experimental research that uses pretest-postest control group design. The population of this research is all grade VIII students of SMPN 1 Alas Barat in the academic year 2013/2014 and the sample of this research is grade VIII3 as experimental group and VIII4 as control group that determined by cluster random sampling technique. The instrument thet used to collect the data is test that made in terms of multiple choices and essay test. The data is analysed by statistical formula of N-Gain and t-test. The result of N-Gain of experimental group concepts mastery is 0,5% and control group is 0,2%. Meanwhile, the result of N-Gain of experimental group creative thinking ability is 0,3% and control group is 0,1%. The resultof t-test shows that tobtined of concepts mastery is 1,877 ≥ ttable is 1,671. Whereas, for creative thinking ability shows that tobtined is 1,998 ≥ ttable is 1,671. It means that there is a difference of concept mastery and creative thinking ability of students on the material of vibrations and waves. Therefore, it can be concluded that the use of virtual laboratorial has an effect towards concept mastery and creative thinking ability of students on the material of vibrations and waves.

Abstract. The purpose of this research is to develop "learning media based on moodle" for Basic Physics lecture. The study was conducted with 4D development medel for 2 years. In the first year, research focused on developing the moodle platform through define, design, and develop phases. The second year, performed refinement with product re-validation and disseminate. The development of moodle platform design is done offline and online using moodle software version 2.0. Offline development is done to organize story boards, page navigation, profile settings, administration settings, and management course settings. Online development is done so that Basic Physics learning can be accessed anywhere, so that students can learn more easily and flexibly. The results of the development and field tests show that the developed product is declared eligible to be used to support the learning process. Students responded positively to the moodle-based media developed.

The purpose of this study is to examine the effect of the use of virtual labs on problem-solving ability of students to the concept of electricity. The subjects were students of physics education at Mataram University. Students were divided into two groups: experimental and control group. The research instrument used was in the form of problem-solving ability tests on electricity concept. The tests employed the form of essay that represent concepts about electricity being studied. The results showed the effect of the use of virtual labs on problem-solving ability of students to the concept of electricity. It can be seen from the different improvement of problem-solving ability in both groups. Problem-solving ability of experimental group is higher than the control group. From the analysis of these problem-solving steps, it can be seen that general students in both classes have the same ability to identify problems and define goals. In the next step, the different improvement in problem-solving skills in the two classes is significant. Experimental class' students have a higher ability to plan and implement problem-solving solutions than those of control class.
