Isoenzymes are variant forms of the same enzyme activity that exhibits different tissue distribution. When cells are damaged, intracellular content leaks into the blood stream, making them potential biochemical markers. Undergraduate health sciences students are expected to interpret laboratory findings of serum levels of biochemical markers and…

The Griess assay is widely used by regulation agencies as an official method for nitrite quantification in water and food samples. In Brazil, the official method, which has been used to determine nitrite in food, was described by Instituto Adolfo Lutz (283/IV) in 1984. It uses 8 mL of reactants and provides 50 mL (reactants plus sample) of waste…

This article explores the emergence and development of writing centers in Brazil, using the author's experience founding the Centro de Assessoria de Publicação Acadêmica (CAPA) at the Universidade Federal do Paraná as a case study. The author provides some historical context about Brazilian education and its traditional "banking model"…

In the first decades of the twentieth century, amidst the emergence of experimental psychology, Latin American educators became pedagogical innovators and advocates of school reforms. They used the classroom as a laboratory to study children's intelligence and collect data that could potentially improve their education. This paper traces…

This paper addresses the fundamentals, structuring, and application of a Formative Dimensions for Green and Sustainable Chemical Education (Formative Dimensions -- GSCE) qualitative evaluation tool of experimental processes. This instrument was created considering the need to resignify laboratory practices in Chemical Education. Qualitative…

Antioxidants are molecules that act against free radicals, and this effect can bring many benefits to health and society. Antioxidants can be found in various matrices of nature, such as fruits and plants. Some studies have shown that "Rhizophora mangle," a typical mangrove plant, is rich in antioxidants. People report its use for…

This paper analyzes the role of the university research laboratory in university-industry interactions for technology transfer. Specifically, it examines how the laboratory research infrastructure, team qualification and local incentives influence knowledge and technology transfer in biotechnology. Despite the importance of the research laboratory…

This work aims to describe the socio-technical network of a Chemistry laboratory in the school "Professora Maria do Rosário Castaldi", a State Center for Professional Education in the city of Londrina, Brazil, taking the translation theories proposed by Bruno Latour as motivation. The observation data were either recorded in audio or…

One of the keys to achieving the United Nation's Sustainable Development Goals (SDGs) in education is to introduce novel pedagogical strategies into university curricula in order to promote an enhanced acute sense of sustainability in future professionals, teachers, and decision-makers. This paper aims at analyzing the effectiveness of including…

Contribution: This work seeks to ascertain the validity of a remote-controlled experiment of the Physics Remote Lab in the educational context, specifically among students from engineering courses. Background: In 2012, it has been started the development of the Physics Remote Lab at the Federal University of Itajubá, Brazil, a laboratory with a…

Contribution: A didactic methodology, based on analytical expressions and experimental validation, to describe the process of abrupt current interruption in a series RL circuit, that considers real passive components and uses a toggle switch as disconnecting device. Background: In undergraduate courses, circuits adopted in transient analysis…

This study contributes to learning improvement in practical classes in Computer Network technology courses, using the Physical Technological Laboratory (PTL) as a tool. Multimodal narration content analysis was used, which aggregates and organises the data collected in the PTL environment. Based on the results, we infer that both the student and…

Undergraduate-level laboratory experiments that involve the synthesis of nanomaterials with well-defined/controlled shapes are very attractive under the umbrella of nanotechnology education. Herein we describe a low-cost and facile experiment for the synthesis of Cu(OH)[subscript 2] and CuO nanowires comprising three main parts: (i) synthesis of…

This article describes the implementation of a remote access experiment, called Web-lab 1553B (Digital Data Bus Lab), for courses in the Avionics Systems Program. Its main objective is to present a study about the use of two rotation model subgroups: 1) rotation laboratory and 2) station rotation. In the "rotation laboratory" subgroup,…

This study captures student perceptions of the effectiveness of remote learning and assessment in two associated engineering disciplines, mechanical and industrial, during the COVID-19 pandemic in a cross-national study. A structured questionnaire with 24 items on a 5-point Likert scale was used. Parallel and exploratory factor analyses identified…
