Biocatalysis is a fundamental concept in biotechnology. The topic integrates knowledge of several disciplines; therefore, it was included in the course "design and optimization of biological systems" which is offered in the biochemistry curricula. We selected the ciliate tetrahymena as an example of a eukaryotic system with potential for…

There is room for improvement in the amount of active learning that takes place during physiology laboratory exercises. This paper describes a protocol designed to examine the human dive response, with the goal of creating an integrative laboratory experienced focused around improving active learning. The objectives of this laboratory exercise…

Sarah Bearchell is a science presenter and writer working with children and families. She aims to engage her audiences through careful tailoring of activities. She works in mainstream primaries and special educational needs and disabilities (SEND) schools, with visits to science festivals becoming more frequent. Many of the schools she visits and…

In this work we analyze the educational reality of Early Childhood Education classrooms in relation to the teaching of science. A total of 83 students from a fourth-year elementary science teacher training program participated in the study. A 48-item instrument was used to collect data. In general, the results obtained show that sciences are a…

There is an increasing emphasis on fundamental particles, including quarks, in the high school physics classroom. However, many teachers might not feel comfortable teaching particle physics because it is a highly abstract and complex topic, and there are few hands-on activities to help teachers bring it into the classroom. In 2010, a…

Traditionally, human anatomy is taught using cadaveric human or animal specimens, however such materials are not always available or are quite costly. Alternate instructional methods can include software, models, clay models, and illustrations. Unfortunately, while cost effective, these methods lack the ability to demonstrate the "in…

Fidget spinners have become a fixation among school children and adults. Pappas (2017) hails spinners as both a boon to stress relief and a constraint on the ability to focus in persons with Attention-Deficit/Hyperactivity Disorder (ADHD) or autism. Spinners can be a distraction in school classrooms, to the point that many schools have banned…

This paper presents the findings of a three-year longitudinal study (Grades 9-11; N = 756 students in German secondary schools; mean starting age = 14.7 years) that explores the development of and the interplay between upper-secondary students' individual interest and conceptual understanding in chemistry. Students' individual interest was…

A lesson that focuses on the intricate co-evolution of flowers with their pollinators is one way to help students learn the delicate balance in nature and help ensure that our actions do not upset this balance. In this lesson students use the engineering design process to engineer a flower that is a perfect model for its chosen pollinator. Next,…

The American Chemical Society's Chemistry Festivals, or "Festivales de Química," are community events where chemistry professionals, professors, teachers, and students use hands-on activities to engage the public and demonstrate how chemistry appears in our everyday life. The Chemistry Festival Organizers received training from the ACS,…

This article is a reflection on how we can show students that the science we learn at school is present in our everyday lives and that we shouldn't separate them. It is essential that we revise the way we plan lessons and include links that are not obvious to young people in order to develop their ability to research, understand and enjoy science.…

US colleges and universities have known for decades that higher percentages of racial and ethnic subgroups leave STEM majors, contributing to racial inequality in STEM professions. Many interventions have been developed, yet the disparity persists. A partial flipped pedagogical model is presented for a General Chemistry 1 (GChem1) course that is…

Attitude toward science has been recognized as highly influential in students' engagement with science and future career choices. Science is important in our everyday lives as well, in a society demanding more scientific vocations and higher levels of scientific literacy. There is little research on how attitudes develop and evolve at early ages,…

The 'Moss Safari' activity was developed to assist with knowing which organisms to look for when observing a drop of water squeezed from moss for the first time. In this case study, the activity was introduced online to 34 trainee science teachers. This was followed by a post-session questionnaire evaluating their experience of the Moss Safari.…

Asking questions is an important way of acquiring information and knowledge and plays a significant role in a child's learning processes. In this study, we examine what characterises the questions asked by children to their teachers in two kindergartens (4-6-year-olds) and six primary school classes (2nd-4th grade) when situated in a natural…
