Few would deny that teachers play a decisive role in the learning-teaching process of students. The learning-teaching process with a gender equity perspective is an important tool to improve the participation and success of women in chemistry. The learning-teaching process with a gender equity perspective was analyzed using the final scores of two…

Several traditional chemistry lab experiences were replaced with a problem-based learning (PBL) experience in a university general education, conceptual chemistry course. Students worked in small groups on an authentic chemistry problem in which each student played a different role (Scientist, Engineering, Marketing Manager, Safety Officer, or…

The current study examines the progress of 8th-grade student drawings and written explanations of chemical phenomenon, subsequent to being involved in an instructional strategy that explicitly involves drawing as a supportive toll to construct scientific explanations. Additionally, the study examines the association between the representation of…

This study consists of a longitudinal research using an active methodology to teach the contents of the periodic table to high school students, based on project-based learning and WebQuest. The aim of this investigation is to study the relationship between learning the periodic table and the type of strategy that students choose to achieve the…

This study examined assessment item difficulty patterns in two energy aspects, energy source/form/transfer and energy degradation/conservation, across and within science disciplines. The participant students were taking at least one college-level introductory science course. Findings showed a common pattern of item difficulties for the two energy…

From its inception in 2016 through 2019, the Baltimore SCIART Consortium offered an annual 10-week interdisciplinary summer research program for undergraduate students. Each year, the program mentored approximately 10 students, many from primarily undergraduate institutions including minority serving institutions and historically black colleges…

Serious game-based learning coupled with just-in-time teaching strategies was applied by offering six different questionnaires to evaluate student knowledge about the safety issues and theoretical concepts and protocols of laboratory exercises. The questionnaires were presented with an appearance similar to that of computer games by means of the…

Despite advances in software development, symmetry-related topics are among the most important yet confusing concepts in crystallography training for chemistry students who routinely use small-molecule crystallography in their scientific study. The case-based learning approach is very effective in stimulating students' interests in self-exploring…

The aim of this work was to design, deliver, and evaluate group case studies focused on the integration of analytical and medicinal chemistry with pharmacy practice. A patient-centered beta-blocker workshop was developed and delivered to year two MPharm and BSc students. Students were tasked with reviewing patient clinical data along with…

In this laboratory experiment, the synthesis and characterization of H[subscript 5]PV[subscript 2]Mo[subscript 10]O[subscript 40]@Cu[subscript 3](BTC)[subscript 2] (denoted as NENU[subscript -9], H[subscript 3]BTC = 1,3,5-benzenetricarboxylic acid) and its application in fuel desulfurization were performed. This experiment is designed for advanced…

Chemistry of the environment has been a long-standing and important area of scientific research. Atmospheric chemistry is of particular interest in society due to the impact that rising levels of pollutants are having on the climate. It is well-known that combustion processes create CO and NO[subscript x], which leads to the creation of other…

This study examines gender representation in 10 current (2016-2020) US college-level general chemistry textbooks. On average, females were found to constitute 30% of images and 3% of the named science, technology, engineering, math, and medical (STEMM) professionals in the index. A male name appears on average every four pages of text, while a…

The Reaction Coordinate Diagram Inventory (RCDI) was developed to measure chemistry students' thinking and confidence when interpreting the kinetic and thermodynamic information encoded within reaction coordinate diagrams (RCDs). The RCDI was designed based upon analyses of qualitative data collected in semi-structured interviews with general…

This contribution reports the process and outcomes of a multiyear effort that supported institutions in reforming general chemistry using multidimensional learning approaches in the form of performance expectations. Performance expectations are based on evidence-centered assessment design principles and describe what learners should be able to do…

This study addresses the use of epistemic criteria related to the scientific practice of inquiry in the context of environmental chemistry. In particular, it analyses the type of criteria that are used by pre-service teachers when assessing the adequacy of several scientific procedures for identifying microplastics in beach sand, as well as…
