Opportunities to engage with science exist in a variety of non-formal educational contexts, but rarely have studies examined ways to leverage science interest and learning at community science events and other single-attendance occasions. This study builds on Yeager and Walton's (2011) concept of brief, wise interventions by using open-ended…

The liquid nitrogen cloud demonstration is an effective, dramatic, large-scale demonstration to illustrate gas laws and cloud/fog (aerosol) formations for classes and large-scale outreach events. When performed at full scale, it is common to produce a cloud 20-30 feet in height. Its effect can be further enhanced by adding brightly colored…

Most constructionist efforts have focused on supporting learners with tools for designing with digital and/or physical media. Recent developments in life sciences now allow K-12 learners to design with living materials, or to biodesign. In this paper, we report on the development of a biodesign studio activity called biocakes wherein teams of high…

A Foldscope is an ultra-affordable paper microscope with a magnification up to 2000X and 2 micron resolution. It is economic, durable and easy to handle tool for scientific studies. Many govt. schools of Kamrup district, Assam found it difficult to use microscope in their regular practical classes for its complexity and high cost. For…

Empowerment of creative thinking skills is important in every lecture activity, including practicum. This study aimed to analyze students' creative thinking skills in Plant Microtechnique practicum. This research used descriptive method in which the participants were the seventh semester biology education students (n=20) of State University of…

During their first physics courses, most students struggle with mathematical concepts that are used but not fully understood, for example, the appearance of infinity in introductory physics exercises. In many cases, these concepts are critical to understanding the underlying physical phenomenon. Typically, most books do not place much emphasis on…

A laboratory exercise for undergraduate advanced students of enzymology and biocatalysis is presented. Since enzyme assays can be quenched or continuous, this experiment compares the performance of two quenching agents for lactase, in a continuous setup. Enzymatic activity of [beta]-galactosidase ("Aspergillus oryzae") was determined…

One of the objectives in the science National Curriculum in England is to 'observe changes across the four seasons' (DfE, 2013: 9). The winter months can be a busy time for teachers, but can also cater for a wide range of science experiments based around the season. Practical investigations based on winter themes can hold a sense of magic and…

The traditional treatment of the electric circuit in textbooks can be criticized in at least three respects: A) Knowledge of the global aspects of the electric circuit as a system is essential for a deeper understanding. However, this is not sufficiently emphasized. B) The presentation of the term "potential difference" or…

This study analysed secondary school teachers' self-reported learning during their participation in a long-term, non-formal scientific activity in the form of a crystal-growing contest. Therefore, the purpose of this research is to explore in-service teachers' experiences and describe the different types of learning that they report they have…

Background Study: Developments in science and technology, have created a need for technology-supported learning environments. Robotics is a technology widely used in science education. Collaborative learning is one of the methods used in education based on the constructivist approach. Using robotic and cooperative learning together is a new and…

The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

Researchers and educators have been exploring systems thinking (ST) in chemistry education to better equip citizens for 21st century challenges; however, little is known about students' perspectives and experiences. In this study, we investigated students' perspectives of ST and their experiences with ST activities. We designed and implemented a…

This study revamps and optimizes the teaching and learning process and instrument for the classic binary vapor-liquid equilibrium experiment by combining activity coefficient model simulations and practical exercises. Our teaching process combines a software simulation and practical exercises. Utilizing Aspen software, students can predict phase…

"Productive Uncertainty in Science Education" provides the support that teachers and students need for more complex science investigations. Science is driven by the need to manage uncertainty--uncertainty about how to explain the world, but also how to represent the world in an investigation, what to measure, and how to convince peers to…
