CRISPR-cas technology is being incorporated into undergraduate biology curriculum through lab experiences to immerse students in modern technology that is rapidly changing the landscape of science, medicine and agriculture. We developed and implemented an educational module that introduces students to CRISPR-cas technology in a Genetic course and…

This research aims to investigate the effect of socio-scientific issues (SSI) based instruction on preservice science teachers' soft skills and environmental awareness. By applying cluster random sampling, 83 preservice science teachers (PSTs) were selected from the Department of Science Education at a university in Indonesia. The participants…

Many physics learners take the specific mathematical representations they are using as part of their learning and doing physics for granted. The paper addresses this problem by highlighting two goals. The first is to show how a historical investigation from history of science can be transformed into a concrete lesson plan in physics, in a physics…

Using a joystick module, we followed the movement of a chaotic magnetic pendulum. The pendulum bar was attached to a joystick that served as a pivot point and biaxial angular motion sensor. Using an Arduino board, we could follow the position as a function of time along both the "x" and "y"-axis and draw a graph showing the…

This article reports on research investigating the experiences and resources that make science thinkable for undergraduate science majors as they engage in postsecondary science contexts. We regard these experiences and resources as contributing to science majors' "science capital," and we suggest that science capital accumulates over…

In biological research, generic questions that are derived from perspectives (ways of looking at and thinking about life processes) help in generating specific questions. In this study, we used perspective-based generic questions as scaffolds to support student teachers in increasing the quality and quantity of their questions about biological…

Elementary teachers are tasked with teaching the language and literacy strategies and skills leading to reading comprehension while also teaching disciplinary content that is the subject of texts, frequently with limited instructional time. Prior research demonstrates that an integrated approach to science and literacy instruction featuring…

The bromination of six isomeric alcohols is adapted to a discovery-based organic chemistry laboratory experiment, whereby students are provided an alcohol starting material and are charged with determining the product or product mixture produced using relevant spectroscopic data. The experiment solidifies NMR analysis skills while reinforcing the…

Conceptual teaching was developed three decades ago as an alternative to conventional teaching approaches. It promised a significant shift in teaching practices across different disciplines and age groups. Traditionally, science subjects in high school tend to be content-heavy. Teaching science, especially biology, is still rooted in teaching…

This study tested how different implementations of explaining and drawing activities affect learning from a multimedia science lesson. After studying a multimedia slideshow about the human respiratory system, college students (n = 145) were assigned randomly to one of four learning activity conditions: write explanations before drawing pictures…

We have developed a new foundation-level course at our institution that links the concept of chemical equilibria from four of the traditional subdisciplines (analytical, biochemistry, inorganic, and physical). The course, entitled Solution and Solid State Chemistry (CHEM 210), is designed to serve our chemistry and biochemistry majors, as well as…

This work presents a simple protocol that demonstrates the use of an inexpensive household carbon monoxide detector as a useful tool to detect the release of carbon monoxide gas from thermal cheletropic decarbonylation reactions. The carbon monoxide detection method described has been employed in a short series of reactions used in a university…

We often say food and fuels "contain" energy. It is more accurate to say that energy is stored in the "fuel-oxygen system" generated during photosynthesis. It is definitely "not" stored in fuels or food (except for the very small amount of energy that can be obtained during anaerobic respiration). Aerobic respiration…

The onset of the COVID-19 pandemic in 2020 greatly impacted all forms of social activities globally, including traditional classroom activities across all levels of instruction (kindergarten to universities). While online and blended learning (including MOOCs) have been an active subject of research and discourse during the pre-pandemic days,…

Developing student capacity for the science, technology, engineering, and math (STEM) workforce requires not only better preparation in specific content and skills but also better preparation in understanding the goals that STEM fields can afford. In particular, stereotypic views that STEM fields lack communal opportunities to work with and help…
