We explored the semiotic choices children in grades 1-6 made that nurtured embodied, dramatizing performances in science classes at urban public schools, serving predominantly students of color in a large US city. We studied how such choices in school and home settings (when instruction was remote during the COVID-19 pandemic) were implicated in…

The American Chemical Society advocates a shift from rule-based to risk-based safety education for chemistry graduates, emphasizing meaningful student engagement in the risk assessment process for laboratory work. To implement this paradigm shift, we introduced RAMP (Recognize Hazards, Assess Risk, Minimize Risk, and Prevent Emergencies)-based…

Biology teachers received professional development to effect instructional changes that ensure student cognitive engagement and knowledge acquisition at higher cognitive levels. We asked the following questions: 1) What are the initial needs of teachers to promote active learner engagement and knowledge acquisition at higher cognitive levels? 2)…

Both lecture and laboratory courses of biochemistry are important professional courses for undergraduates with biology related majors. Course optimization and update is crucial but challenging, especially for the laboratory course. Although taught separately, here we showed a strategy to bridge the two courses and promote the improvement of both.…

The problem addressed by this study was to determine the influence of high school start times on students' academic achievement and precisely how this impacts the scores students received on the Biology I End of Course Exams. It also determined if there was a difference in influence between males and females. This was determined by comparing the…

Reduced hours of instruction are reported within the gross anatomy education literature. Anatomy instruction continues to be challenged with motivating and inspiring learners to value the contribution of gross anatomy knowledge to their career development alongside increased organizational demands for efficiency and effectiveness. To address these…

Molecular biology, broadly defined as the investigation of complex biomolecules in the laboratory, is a rapidly advancing field and as such the technologies available to investigators are constantly evolving. This constant advancement has obvious advantages because it allows students and researchers to perform more complex experiments in shorter…

Past research repeatedly revealed students' struggles to understand chemical equilibria, especially concerning their dynamic nature. Black-box simulations have proven to be helpful here. However, the effect is strongly dependent on the quality of teaching, the design principles of which are not yet fully known. One aspect of debate concerns the…

The Next Generation Science Standards (NGSS) demand that science educators shift from traditional to NGSS teaching and learning. The purpose of this qualitative case study was to explore the change process of shifting from traditional one-dimensional teaching to NGSS three-dimensional teaching and learning. A survey was sent to all science…

This study used a cluster randomized controlled trial to investigate the effectiveness of two approaches to increasing middle school students' science learning when using an inquiry-based science curriculum. Eighty-nine schools, with 253 teachers and 20,591 students, were randomly assigned into one of three conditions: (a) a treatment condition in…

This study aimed to determine the effect of using a virtual anatomy system (VAS) on student learning with regard to reproductive system with respect to the acquisition of misconceptions. This study used an experimental method by comparing the results of the class learning using virtual laboratory media with a control class. The result showed that…

Molecular imprinting technology holds significant potential for applications in chemical analysis and detection. In order to integrate the fundamental knowledge of polymer chemistry, electrochemistry, and analytical chemistry with practical applications and cutting-edge research, we proposed a comprehensive experiment of the preparation,…

Metabolism is always a challenging topic in biochemistry. In our project, a courseware called "Metabolism Metro" was developed. "Metabolism Metro" is a self-learning tool which aims to facilitate students learning of metabolic pathways in an interactive and easy-to-understand manner. The courseware includes both pre-class and…

The development and acquisition of science process skills (SPS) in science education are closely linked to the development of 21st-century skills and improvements in academic performance. To help facilitate the development of SPS in learners, teachers should acquire and exhibit SPS. This study assesses the SPS acquired by final-year students in a…

Although formulating a broadly accepted definition of scientific literacy may be challenging, it is widely recognized that Nature of Science (NOS) is an essential component of it. There are different ways to define NOS. In some cases, NOS can be conceptualized through a number of general NOS aspects like for instance science's empirical basis or…
