    This research aimed to compare how prospective science teachers’ attitudes towards chemistry laboratory and chemistry lesson changed after participation in inquiry-based instructions that were conducted in real and virtual laboratories. Thirty-four freshman prospective science teachers from an education faculty participated in the research and participants were assigned as Group-1 (N=17) and Group-2 (N=17). While Group-1 was accomplished inquiry-based instruction in the real laboratory, Group-2 was conducted the same instruction in the virtual laboratory. As a data source, attitude towards chemistry lesson scale and attitude towards chemistry laboratory scale were used. The semi-constructed interview was also conducted with all participants. According to results, although all the prospective science teachers’ attitudes toward chemistry lesson and laboratory improved significantly in both real and virtual laboratory environments, improvement in the prospective science teachers’ scores in a real laboratory environment significantly higher than those in the virtual laboratory. In addition to these, semi-structured interview results cohered with the results of the scales

    Mapping e-Science’s Path in the Collaboration Space: Ontological Approach to Monitoring Infrastructure Development

    Get PDF
    In an undertaking such as the U.S. Cyberinfrastructure Initiative, or the UK e-science program, which span many years and comprise a great many projects funded by multiple agencies, it can be very difficult to keep tabs on what everyone is doing. But, it is not impossible. In this paper, we propose the construction of ontologies as a means of monitoring a research program’s portfolio of projects. In particular, we introduce the “virtual laboratory ontology” (VLO) and show how its application to e-Science yields a mapping of the distribution of projects in several dimensions of the “collaboration space.” In this paper, we sketch out a method to induce a project mapping from project descriptions and present the resulting map for the UK e-science program. This paper shows the proposed mapping approach to be informative as well as feasible, and we expect that its further development can prove to be substantively useful for future work in cyber-infrastructure-building.e-Science, virtual laboratory ontology, collaboration space, project mapping, cyber-infrastructure building

    PRELIMINARY STUDY: CHEMISTRY LABORATORY VIRTUAL INNOVATION AS AN OPTIMIZATION OF SCIENCE LEARNING DURING THE COVID-19 PANDEMIC

    Get PDF
    The purpose of this research is to conduct a preliminary study to create a virtual chemistry laboratory innovation to optimize learning during the Covid-19 pandemic in the Natural Science Education Study Program of the Teacher Training and Education Faculty Universitas Sebelas Maret (FKIP UNS). The Natural Science Education Study Program of FKIP UNS itself teaches chemical concepts that require laboratory activity. This study used the descriptive qualitative method. Data was collected using observation, interviews, and analysis of related documents and equipped with a Focus Group Discussion (FGD) with students and lecturers (Science Education and Chemistry Education FKIP UNS). The results showed that 11 chemistry practicums required virtual laboratory innovation in the Natural Science Education Study Program of FKIP UNS due to restrictions on the use of laboratories by the campus. It was concluded that a virtual chemistry laboratory was needed as an alternative to student practicum activities to maintain and optimize laboratory skills in online learning. In addition, the developed virtual laboratory needs to be embedded online and can be accessed through various gadgets so that it can be used anytime and anywhere

    : We have developed a virtual laboratory model for teaching modern physics. The purpose of this study is to examine the effectiveness of a virtual laboratory model of modern physics on students' generic science skills. The study involved 64 students who were divided into two groups, the experimental group and control group. The research instrument used a generic science skills test that is integrated with the mastery of concepts of modern physics. Data were analyzed by using mean-difference test and normalized gain scores. The results showed an increase in generic science skills in both groups. Indicators showed that the highest increases are logical inference capability and the ability to build concepts. These results indicate that the virtual laboratory model of modern physics is effective to increase students' generic science skills
