During the COVID-19 pandemic, schools did not open face-to-face learning services. The Ministry of Education and Culture has issued a policy learning from Home (BDR) to support the principles of the Education Policy in the COVID-19 Pandemic that the health and safety of students, educators, education personnel, families, and the community is the top priority. However, learning in Vocational School (SMK) is mostly based on practice so that BDR activities cannot be implemented. One thing that is done to overcome this is that some practicum activities can be executed using multimedia known as virtual laboratories. The aim of this study is to conduct a need analysis for the development of a virtual laboratory.  Needs analysis is carried out to gather data about gaps and needs as well profiles of students that can be used as a basis or reference in developing virtual laboratory at the next stage. Data collection was carried out by means of observation, interviews, and distributing questionnaires. The results showed that a virtual laboratory was needed to support practical learning for vocational students.

A presente pesquisa teve como objetivo analisar as representações quantitativas que estão presentes nas interfaces de laboratórios virtuais à luz da Semiótica Peirceana. É uma pesquisa qualitativa exploratória, realizada no repositório portal PhET–Interative Simulation. No percurso da pesquisa foram encontrados 51 aplicativos, desses seis exibiam características de laboratório virtual e três foram semioticamente analisados. Os resultados indicam que três laboratórios apresentam disposições parcialmente satisfatórias nas representações quantitativas que abordam. Esses podem vir a contribuir para o fortalecimento do ensino da Química, por meio de ilustrações, simulações e a participação interativa do estudante. Quanto às possibilidades, esses oferecem diferentes ambientes, formatos e modelos para o estudo desta ciência. Também foram encontradas limitações como a insuficiência de signos iconográficos de ordem quantitativa considerados indispensáveis na conjuntura conceitual de determinados tópicos da Química. As indicações desta pesquisa são para se pensar a respeito dos signos que vão representar a natureza quantitativa da Química, transformando os desafios em possibilidades para os processos de ensino e aprendizagem desta ciência. Palavras-chave: Semiótica. Ensino de Química. Laboratórios Virtuais. Abstract Virtual laboratories used in chemistry teaching are important didactic resources for the advancement of teaching and learning processes, while they can contribute to mediation actions in the knowledge construction. This research aims to analyze the quantitative representations that are present in the virtual laboratories interfaces in light of Peircean semiotics. It is an exploratory qualitative research, conducted at the portal PhET – Interative Simulation. During the research, 51 applications were found, of these, 6 exhibited virtual laboratory characteristics and three were semiotically analyzed. The results indicate that three laboratories have partially satisfactory arrangements in the quantitative representations they address. They can contribute to the strengthening of chemistry teaching through illustrations, simulations and interactive student participation. As for the possibilities they offer different environments, formats and models for the study of this science. Limitations were also found as the insufficiency of quantitative iconographic signs considered indispensable in the conceptual conjuncture of certain topics of chemistry. The indications of this research are to think about the signs that will represent the Chemistry quantitative nature, turning the challenges into possibilities for the teaching and learning processes of this science.

While we already know that clearly utopian or dystopian depictions of human-machine relationships in science fiction film can be effective rhetorical models that shape our ideas of HRI, this paper argues that sci-fi films, like Marjorie Prime (2017) and Be Right Back (2013), can also function as more neutral virtual laboratories that allow viewers to actively explore the pros and cons of those relationships in more detail. This paper specifically explores both Marjorie Prime and Be Right Back for the way they evoke questions or ideas about what it means to be human, what it means to interact with AI, and what a meaningful relationship between these two can bring. By following a neoformalist analysis, I will show how these cases continuously present us with devices that force us to reassess the role of robots in our lives. They do this by using deceptive, reflective, and confrontational strategies within characters, cinematography, narrative structure and setting.

This chapter discusses the development of a virtual laboratory (VL) named “EduPhysics,” an assistive software tailored around the Namibian Physical Science textbook for Grade 8 learners, and examines the viability of implementing VL in education. It further presented reviews on the role of computer simulations in science education and teachers' perspective on the use of EduPhysics in physical science classrooms. The chapter adopted a mixed method with an experimental research design and used questionnaires and interviews as data collection tools in high school physical science classes. The analysis found that there are limited resources in most physical science laboratories. Computer laboratories, however, are well equipped and have computing capacities to support the implementation of VL. It was concluded that virtual laboratories could be an alternative approach to hands-on practical work that is currently undertaken in resource-constrained physical science labs. For future work, augmented reality and logs will be incorporated within EduPhysics.

Laboratory work in science education is essential for students' conceptual understanding of natural phenomena. Computer-simulated laboratory experiments have been proposed to facilitate traditional laboratory work. A virtual laboratory was designed to enable students to collaboratively discover the concept of gas solubility in water at different physiological conditions. The virtual laboratory was developed through a design experiment involving three successive versions with different guiding structures. Analysis of 12 dyads' reasoning about gas solubility in water revealed that the problem was not primarily for the students to realise how the volume of gas changed, but rather to understand the concept of solubility of gases. It was also observed how the guiding structures within the three different versions influenced the students' reasoning about the concept. The analysis indicates that the affordances of virtual laboratories might, to a certain extent, enhance joint discovery of a scientific concept.
