We report on the study of student difficulties regarding a heat engine in the context of a Stirling cycle by the method of measurement. An in-class test about a Stirling engine with a regenerator was taken by three classes, and the students were asked to perform one of the most basic activities--calculate the efficiency of the heat engine. Our…

Along with the COVID-19 pandemic, universities in Turkey as well as all over the world have started to carry out their education activities with the distance education method. In this case, many difficulties were encountered in the application of the Biology course, which is one of the applied courses carried out in the laboratory. Virtual…

Inquiry practices can be integrated into various settings that differ in terms of their constraints and hence in the scope and depth of the practices that students experience. Key policy papers suggest implementing a gradual learning sequence for inquiry practices so that students' learning experiences in more constrained settings can serve them…

This study has proposed a simple method to show the convective heat transfer. The object in this study is an air conditioner (AC) as a simple case of convection. In addition, AC is also easy to find in the class because most classrooms in Indonesia installed AC. Usually, a visualization needs special software (i.e. MatLab or others) and good…

This paper presents an insight on the pedagogy and strategic design of the organization of the four experimental subjects of the Chemical Engineering Degree Curricula at the Universidad Politécnica de Madrid (GIQ-ETSII-UPM). Outcome-based learning is applied, focused on the student's work, centering explicitly in Experimental Design outcomes.…

Water is a special substance. Not only do humans rely on water for survival, but it is also fascinating to play with and makes a great topic to investigate. Many simple investigations can be done with water, at home or at school, to guide children's science learning. This article describes a sequence of online learning experiences that were set…

This paper reports the findings of the second and the third year of a four year longitudinal empirical research into the modification of 'step-by-step' instructions to practical activities which require one or more steps to be designed by the students. This method had been successfully applied for a short period for 14-15 years old students.…

In recent years teachers' education programs encourage preservice teachers to practice a variety of assessment methods to prepare them to be highly qualified practitioners who are capable in enhancing students' scientific understanding. Formative assessment (FA) -- also known as assessment for learning -- involves the process of seeking and…

The need for geoscience students to develop a quantitative skillset is ever increasing. However, this can be difficult to implement in university-style lecture courses in a way that is both manageable for the instructor and does not involve lengthy, potentially repetitive, question sheets for the students. Here, a method for teaching dimensional…

1000 Future Scientists (1000FSc) is a university extension project developed at the Department of Chemistry in Federal University of Minas Gerais (UFMG). Conducted by the Higher Education Administrative Technicians and Professors, it presents the university to the community by proposing an engaging experience for elementary and high school…

Universities play an important role in society and in providing solutions for its problems. Environmental pollution is one of the most serious problems facing the world today. Thus, universities are increasingly including subjects related to the environment and its conservation both in their educational and research programmes. Generally,…

In Vietnam, nuclear physics is a fundamental part of the national curriculum for physics. However, due to a lack of experimental apparatus (detectors, radioactive sources, etc) at most of the schools, the majority of students do not have opportunities to experience the phenomena behind the concepts. Moreover, safety is another major concern when…

Understanding the controls of the oxidation rate of iron (Fe) in oxygenated aquatic systems is fundamental for students of the Earth and Environmental Sciences as it defines the bioavailability of Fe, a trace metal essential for life. The laboratory experiment presented here was successfully developed and used during a third-year undergraduate lab…

In this paper, the inclusion of history and philosophy of science in science teaching is proposed with the goal of depicting pre-service primary teachers' perception of the role of historical experiments in learning science and the nature of science. In order to achieve this, a teaching-learning sequence was designed and conducted in the context…

Brazil is a country that does not invest enough in basic education, thus leaving a gap in the knowledge of young people studying in public schools and jeopardizing their future. One of the main ways to get into college in Brazil is through the National High School Exam (ENEM), a multiple-choice test administered by the National Institute of…
