My thesis work is focused on conceptual and epistemic learning and characterizing the environments in which this learning takes place. Earlier studies conducted by the Stowe group explored how instructional practices, instructional emphasis, and assessment emphasis relate to student outcomes in general and organic chemistry courses. Student…

The ability to express scientific concepts in mathematical terms and integrate scientific and mathematical reasoning about a phenomenon is a foundational cognitive process involved in scientific thinking. This process called "blended math-science sensemaking" (MSS) is a desired skill for all science, technology, engineering, and math…

Design activities are gaining interest as rich contexts for learning science, technology, engineering, and mathematics (STEM) subjects. STEM teachers may find this challenging however, as designing requires support that they are not used to providing. In a subject like chemistry, teachers would have to balance creativity and responsibility for the…

Escape rooms are making their way into the chemistry classroom as a learning tool. However, escape rooms require a large amount of preparation and setup, and they are only novel and exciting for a single play-through. For escape room games to be incorporated into multiple class periods, they must be streamlined for reuse. In this work, I introduce…

Integrating science and engineering has become a focal point for current research in science and STEM educational fields. Infusing engineering design as an application of scientific principles is beneficial, as it demonstrates an authentic, real-world application and allows for not only student engagement and enthusiasm, but also an avenue to…

Despite chemistry's recognized importance to multiscale industrial and environmental processes, first-year undergraduate chemistry is often regarded as comprising a collection of unconnected topics with little relevance to everyday life. Implementing systems thinking into the chemistry curriculum can help to contextualize chemistry learning and…

The periodic table is a fundamental tool used in chemistry classes that allows students to systematically understand different types of elements and their physical and chemical properties. While many textbooks emphasize the historical process of classifying substances, they often superficially elucidate the achievements of chemists such as Dmitry…

It is the responsibility of chemistry educators to identify and implement instructional strategies, such as introducing educational board games that can foster active and constructive learning and promote an enjoyable learning experience. This study aimed to design, develop, and evaluate a board game that has the potential to be used as a…

Atomic orbitals represent an essential construct used to develop chemical bonding models, upon which other more advanced chemistry topics are built. In this article, we share a series of active-learning activities and a gamified approach to develop students' representational competence about atomic orbitals and to engage students in learning the…

Many approaches to teaching Newman projections and conformational manipulation rely on lecturing using only two-dimensional representations. While molecular models are recognized as useful learning tools, students are often left to figure out how to use them during the initial learning process. The availability of basic online molecular models…

Teaching natural sciences can be challenging, especially with unmotivated or disinterested students. The challenge increases when the term "Didactics" appears in the subjects under study, for example, with Didactics of Natural Sciences. The present work details the design and execution process of an escape room experience used as a…

Frost diagrams provide convenient illustrations of the aqueous reduction potentials and thermodynamic tendencies of different oxidation states of an element. Undergraduate textbooks often describe the lowest point on a Frost diagram as the most stable oxidation state of the element, but this interpretation is misleading because the thermodynamic…

Students tend to think of their science courses as isolated and unrelated to each other, making it difficult for them to see connections across disciplines. In addition, many existing science assessments target rote memorization and algorithmic problem-solving skills. Here, we describe the development, implementation, and evaluation of an activity…

This study investigated students' meaning-making of polymeric concepts during modelling and discuss students' creation of visible representations in chemistry. The analysis combines a phenomenographic and social semiotic approach and leads to the finding and description of 21 different meaning-making processes. We refer to meaning-making as the…

Science educators are integrating more and more computational thinking (CT) activities into their curricula. Proponents of CT offer two motivations: familiarizing students with a realistic depiction of the computational nature of modern scientific practices and encouraging more students from underrepresented backgrounds to pursue careers in…
