Background: STEM education and research are increasingly emphasized by governments worldwide to foster national development and productivity, economic competitiveness and societal wellbeing. There is no exception in Hong Kong, with its desire to promote STEM education and to strengthen Innovation and Technology development in the future. Purpose:…

Students often find human anatomy courses to be difficult due to the large amount of content covered at a fast pace, which can result in students failing to retain pertinent information. Superheroes are at the forefront of today's popular culture, with many students identifying with specific characters. Utilizing aspects of students' lives, or…

This century, the twenty-first century, is a century of science and technology explosion. This is the period when the boon of science has arrived in almost every corner of the world. One such example is exposure to information (data) using a cell phone, bypassing a computer. This has made information available to the masses at a much cheaper rate…

The purpose of the study is to see if there is a significant difference in chemistry exam achievement growth for 10th grade students in classes with problem-based learning compared with those students in classes with direct instruction. The state in which the study was conducted is developing new standards that are challenging students more than…

Surface chemistry is a challenging realm for most students because of its abstract nature and numerous associated mathematical equations. Herein we report a set of dedicated sequential inquiry-based learning (IBL) activities enriched with virtual laboratory learning and hands-on instructions. The activities were intended to help students grasp…

A laboratory experiment that exposes students to fundamental concepts in kinetics and statistical thermodynamics to study systems of great current interest in nanotechnology by employing a foundational technique in physical chemistry is described. A modified commercial flash photolysis spectrometer was used to study photoinduced isomerization…

Crystal materials are an important pillar of advanced technology. Among them, the preparation of large-sized single crystal materials is of great importance for their practical application. Herein, we select the well-known nonlinear optical crystal KH[subscript 2]PO[subscript 4] and impressive deep-blue colored crystal CuSO[subscript…

A laboratory experiment was developed for the continuous flow preparation of an aminal derived from the condensation of furfural with morpholine. The experiment introduces the students to concepts of green chemistry, heterogeneous catalysis, and continuous flow. A cheap and easy setup allows the heterogeneous catalyst reactor to be built in class.…

The independent curriculum is designed to be a better future solution for education in Indonesia. This curriculum is expected to reduce the learning losses that occurred after the COVID-19 pandemic. In the independent curriculum at the elementary school level, natural science subjects are changed to natural and social science subjects. Natural…

In an effort to further develop critical thinking and problem solving skills, a guided-inquiry-based, multioutcome organic chemistry synthesis and characterization experiment was developed. Students were provided with the protocol for a time-saving microwave-assisted acetanilide synthesis reaction from acetic anhydride and an unknown primary aryl…

A national survey of chemists (n = 174) explored the self-reported format and focus of postsecondary inorganic chemistry instructional laboratory curricula. Multiple instructional laboratory course formats were observed, including stand-alone inorganic chemistry instructional laboratory courses, inorganic chemistry laboratory instruction as a…

This article attempts to address the challenge that preschool teachers face, when integrating a specific content area, science, with play. The study builds on the theoretical framework of Play-Responsive Early Childhood Education and Care (PRECEC), in which teaching, and play are understood as a mutual activity. In this mutual activity, teachers…

Purpose: This study examined science achievement; science vocabulary knowledge; and the relationship between science vocabulary, language skills, and science achievement in school-age children with language/literacy disorders (LLDs) and typical language development (TD). Method: Thirty-nine sixth graders (11 with LLDs) completed standardized…

Southern blot analysis is an important molecular biology technique for identifying a specific sequence in DNA samples. Although it is no longer used extensively in recent years, the steps and underlying principles of Southern blot are applicable to modern biology. High sensitivity and limited background are keys to successful Southern blots,…

The formation of chemical patterns is in general difficult to control due to the random diffusive motions of the reacting chemical species in solution. In this paper, we present a new method using audible sound to control the formation of chemical patterns obtained in blue bottle experiments. The waves generated on the surface of the solution by…
