<p><strong>Abstract: </strong>The laboratory has an important role in the learning of physics. Tools and materials are limited often used as an excuse for not doing the lab activities. In addition, the characteristics of the most abstract concepts of physics that cause difficulties in teaching it to students. In this research, we have developed several virtual experiments on the concept of optics. Besides as an alternative to the limited laboratory equipment in LPTK, is also intended as a visualization media of concepts to make it easier to understand by students. The purpose of this study was to examine the effectiveness of a virtual laboratory to increase student’s mastery of optics concepts. This research includes research and development, which is divided into three stages: the preliminary study, model design, and testing models phase. The results showed that the virtual laboratory model effectively used in learning of physics. This is indicated by a higher increase in the mastery of the concept of the experimental class than the control class. The highest increase occurred in the concept of geometrical optics by 79.9%.</p><p> </p><p><strong>Keywords:</strong><em>  </em>Virtual Laboratory, Mastery of Concepts, Optics</p><p> </p><p><strong>Abstrak:</strong> Laboratorium memiliki peranan penting dalam pembelajaran fisika.

In this work an interactive teaching tool related to the operable virtual 3-D laboratory has being presented. Though defining the lighting and material, and rendering the scene environment, a remarkable virtual laboratory appears as 3-D figures. As well as combining the ramble, animation and interactivity with the 3-D model, a realistic feel of the experiment presents to us. Data information combine with 3-D model achieve a realistic feel of the experiment and to enhance the students’ understanding of some complex concepts. Based on the virtual laboratory model, a group of experiments are developed, including wind tunnel, a Bernoulli equation rig and a stream line rig, etc.

To improve the quality of the Nuclear Physics lectures in addition to understanding the material as knowledge aspect, students are also expected to practice for the skills. The Nuclear Physics lecture material is microscopic so it requires laboratory activities, but there is no suitable practical tools available in the laboratory of Physics Department, mathatics and science faculty, universitas negeri padang. Therefore, a virtual laboratory model was developed in this research which was supported by students' worksheet. The valid and practical students' worksheet have been obtained. Then, it was tried out to students who take the Nuclear physics lecture to see whether the students' worksheet are effective to support virtual laboratory activities. The research conducted is included in the type of quasi-experimental research. The population is students who take part in the Nuclear Physics lecture in semester January-June 2018. The samples were taken using Cluster Random Sampling techniques. Data on knowledge and skills competencies were analyzed using the t test at a real level of 0.05. Based on the results of data analysis, there were significant differences in the two sample classes. The results of the regression analysis indicate that there is a strong correlation between the use of students' worksheet to support virtual laboratory activities for knowledge and skills competencies.Keywords: Nuclear Physics, Students Worksheet, Virtual Laboratory

This study aims to design and create a virtual chemical textile laboratory model as an effort to improve students' understanding of learning Textile Chemistry, especially on the subject of making cellulose-based regenerative textile fibers that have a high level of abstraction and complexity. Theoretical learning in the form of verbal symbols, empirically is not representative enough to explain the concept of the system that is needed, so that the possibility is not affordable (likely to inaccessible) by students which effected to the lessen of learning experiences. These conditions have implications for the lack of student understanding of these processes which is indicated by the acquisition of low learning outcomes. The specific target of this research is to produce a virtual laboratory device as a simulation medium for learning textile chemistry on the subject of making effective cellulose-based regenerative fibers. Furthermore, the model developed is validated to get input from experts related to the technology used, design and process content in the developed model. The validation results show that this model is suitable for use in the study of textile chemistry and can be used to improve students' understanding of the material for making cellulose-based regenerative textile fibers. In the limited trials that have been carried out, there are some features, image choices, and some simulations that need to be refined to avoid students' misinterpretations of the planned chemical process concept. Students involved in the trials are more motivated to continue learning related concepts that have been learned. In subsequent studies this model will be tested on a broader scale to measure its effect on the mastery of concepts and its ability to improve learning outcomes in textile chemistry courses, on the material for making cellulose-based regenerative fibers.

This study is devoted to the peculiarities of online education, namely, the use of virtual laboratories. The emphasis is being placed on the development of a laboratory model that can take advantage of the available online courses and adapt them for students with special educational needs. The research describes the learning process in a virtual laboratory, options for integrating online courses, and the ways of presenting them to students with certain educational needs. As a result, a virtual laboratory model was developed; it has been primarily designed for people with hearing and vision impairment, and musculoskeletal disorders. Thus, each user category was submitted several options for the educational process implementation within the virtual laboratory. The theoretical model allows creating a virtual laboratory to teach students with special educational needs. Based on the student experience of using the laboratory, research aimed at searching for new ways of presenting information and improving existing ones could be conducted.
