Problem Based Laboratory Work in Industrial Chemistry – Acquisition, Integration and Applying Knowledge

This research is a research development which aims to 1) Develop a Physics game learning based on Android that is feasible to be used as a learning media on physics subjects. 2) Knowing students' responses to physics game learning based on Android as learning media 3) Knowing that physics game learning based on Android as learning media can improve students' ability to analyze in the chapter of momentum, impulse, and collision. This research uses the ADDIE development model. This research has been tested by 3 media experts and 3 material experts with the results of the assessment stating that the media is feasible to be used as a medium for physics learning. The subjects of this research were 11 students in class X of Industrial Chemistry at the Vocational School of Gula Rajawali Madiun. The results of this research development indicate that: 1) media physics game learning based on android meets the feasibility standard to be used as a learning medium on physics subjects. 2) The learning media of Physics game learning based on Android gets a very good response from students. 3) Physics game learning based on Android as learning media can improve students' analytical skills in the chapter of momentum, impulses, and collisions with an average N-Gain of 0.54 which is in the medium category.

Adalbert Wraný (*1836, †1902) was a doctor of medicine, with his primary specialization in pediatric pathology, and was also one of the founders of microscopic and chemical diagnostics. He was interested in natural sciences, chemistry, botany, paleontology and above all mineralogy. He wrote two books, one on the development of mineralogical research in Bohemia (1896), and the other on the history of industrial chemistry in Bohemia (1902). Wraný also assembled several natural science collections. During his lifetime, he gave to the National Museum large collections of rocks, a collection of cut precious stones and his library. He donated a collection of fossils to the Geological Institute of the Czech University (now Charles University). He was an inspector of the mineralogical collection of the National Museum. After his death, he bequeathed to the National Museum his collection of minerals and the rest of the gemstone collection. He donated paintings to the Prague City Museum, and other property to the Klar Institute of the Blind in Prague. The National Museum’s collection currently contains 4 325 samples of minerals, as well as 21 meteorites and several hundred cut precious stones from Wraný’s collection.

Laboratory Experience

Esta pesquisa teve como finalidade relatar experiências em laboratório, especificamente o Laboratório de Geografia Física - Pesquisa (LabGeoFis-Pesquisa), localizado no Departamento de Geografia, no Centro de Ciências Humanas, Letras e Artes, da Universidade Federal do Rio Grande do Norte. Procuramos relatar, de forma concisa, as principais técnicas aplicadas ao trabalho laboratorial, enfatizado a temática da Geografia Física. Para tecer essas considerações, nos fundamentamos em autores como Venturi (2005) e Rudio (1990), os quais tratam sobre teorias e procedimentos relacionados às práticas de laboratório e a pesquisa descritiva e experimental, respectivamente. Para realizar esta pesquisa, levamos em consideração os trabalhos e as experiências desenvolvidas pelos alunos de bacharelado e licenciatura do primeiro período do curso de Geografia. Os resultados aqui obtidos, nos mostraram a importância dos conhecimentos teóricos aliados com a prática de laboratório.Palavras chaves: Laboratório; Experiência; Técnicas. ABSTRACT This research had the purpose of reporting laboratory experiments, specifically the Laboratory of Physical Geography - Research (LabGeoFis-Search), located in the Department of Geography, at the Humanities, Letters and Arts Center of the Federal University of Rio Grande do Norte. We try to report, in a concise way, the main techniques applied to laboratory work, emphasizing the theme of Physical Geography. In order to make these considerations, we base ourselves on authors such as Venturi (2005) and Rudio (1990), who deal with theories and procedures related to laboratory practices and descriptive and experimental research, respectively. To carry out this research, we take into account the work and experiences developed by the baccalaureate and undergraduate students of the first period of the Geography course. The results obtained here showed us the importance of theoretical knowledge allied with laboratory practice.Keywords: Laboratory; Experience; Technique.
