Photocatalytic hydrogen generation over semiconductor photocatalysts has attracted considerable attention over the past few decades. This experiment is designed for sophomore- and higher-level undergraduates who are in the majors of materials chemistry, analytical chemistry, catalysis, or chemical engineering. In this experiment, CdS nanoparticles…

Due to the COVID-19 pandemic, many universities have switched to online learning platforms, which inhibits engineering students from completing formative hands-on experiments. To address this, we developed at-home experiments for an undergraduate biomaterials course. These inquiry-based learning experiments were well received by students and…

Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

A central goal of introductory physics for the life sciences (IPLS) is to prepare students to use physics to model and analyze biological situations, a skill of increasing importance for their future studies and careers. Here we report our findings on life science students' ability to carry out a sophisticated biological modeling task at the end…

The pendulum was an important scientific instrument in the 17th century. It became a typical textbook problem in the 18th century. After the introduction of vectors in physics in the 1890s, the pendulum problem started to be progressively solved in the manner we know nowadays from introductory mechanics courses. Starting from "F = ma"…

As part of COVID-19 preparedness, a student-developed, Android-based app was used as a pre-laboratory learning aid for a molecular modeling laboratory in a first-year general chemistry course. A worksheet activity with trigger codes and questions related to spatial features of transition metal complexes was designed. Using the Transition Metal…

UV-vis absorption spectroscopy is one of the most accessible spectroscopic techniques at the high school educational level, and it is usually introduced in analytical chemistry courses due to its high versatility and to the wide range of applications in many fields of chemistry. Within this framework, we have developed an easy-to-use"…

Recommendations for enhancing scientific literacy, inclusivity, and the ecosystem for innovation call for transitioning from teacher-centered to learner-centered science classrooms, particularly at the introductory undergraduate level. Yet little is documented about the challenges that undergraduates perceive in such classrooms and the students'…

The level of students' engagement during active learning activities conducted in small groups is important to understanding the effectiveness of these activities. The Interactive-Constructive-Active-Passive (ICAP) framework is a way to determine the cognitive engagement of these groups by analyzing the conversations that occur while student groups…

The global COVID-19 pandemic has had a significant impact on university course design, implementation, and instruction, with many courses being offered remotely rather than face-to-face to prevent the spread of COVID-19. As the COVID-19 pandemic subsides, more and more courses are transitioning back to face-to-face instruction. In this article, we…

Inquiry- and context-based learning (IBL and CBL, respectively) can lead to improved student outcomes, including increased motivation and interest, the development of critical thinking skills, and improved assessment results. This study outlines the application of IBL research projects in third-year university Environmental Chemistry and…

Given the recent state of social distancing, the online lab experience discussed in this article offers an economical and versatile approach to online undergraduate chemistry lab instruction. With videoconferencing software, this experience is easily adaptable to a socially distanced learning environment, although it was initially designed for a…

Scientific reasoning, argumentation, and problem-solving are essential skills in 21st century. They help people solve problems in daily life. This study aimed to investigate the effect of local-based teaching materials on student's argumentation, scientific reasoning, and problemsolving skills using Science Project-based Learning (SPjBL).…

The case study-based module on chemical thermodynamics course (ideal and real gases) was developed to fulfill the needs of undergraduate students in online learning during the COVID-19 pandemic. The purpose of this study was to test feasibility of case study-based module. The case study-based module refers to the 4D model (define, design, develop,…

Chemistry education research has increasingly considered the role of affect when investigating chemistry learning environments over the past decade. Despite its popularity in educational spheres, mindset has been understudied from a chemistry-specific perspective. Mindset encompasses one's beliefs about the ability to change intelligence with…
