Students face various challenges in organic chemistry, including learning complex organic chemistry concepts, applying them to solve problems, and navigating curved arrow notation to depict organic chemistry mechanisms. Given these challenges, many chemistry education practitioners and researchers have focused their efforts on implementing and assessing pedagogical practices that can produce positive outcomes for all students. In this chapter, we describe flipped classroom pedagogy as an evidence-based practice in organic chemistry that has improved student outcomes and addressed learning challenges in the course. We also review key aspects of this practice. In addition, we focus on group activities since they are a common component of flipped classrooms. We will present a case study that analyzes students' reasoning through dialogue when they were engaged in a group quiz activity that was a component of a flipped organic chemistry course. Through the results of this case study, we will make suggestions for how group activities can be implemented to improve students' reasoning skills in organic chemistry.

Organic chemistry students’ use of stability in mental models on acid and base strength
The Brønsted–Lowry acid–base model is fundamental when discussing acid and base strength in organic chemistry as many of the reactions include a competing proton transfer reaction. This model requires evaluating chemical stability via a consideration of electronic granularity. The purpose of this study is to identify students’ mental models on acid and base strength in terms of granularity and stability. Fourteen students enrolled in organic chemistry participated in this case study. Data were collected through semi-structured interviews including total case comparison tasks on stability, acidity, and basicity. Analysis of data revealed that there were four groups of students differentiated by their reasoning: (1) acid and base strength through structure without association to stability, (2) acid and base strength through electronics without association to stability, (3) acid strength associated with electronically centered stability, and (4) acid and base strength associated with electronically centered stability. This characterization can support teaching and research to promote reasoning that leads to a more consistent mental model across acid and base strength.

Stimulating interest in science at an early age is important for STEM education. This work details an educational activity utilizing the anthocyanins found in the butterfly pea flower (Clitoria ternatea). This activity was developed for use in official classroom settings, online, and/or at-home with parental or educator guidance. Primary and high school students aged 7 to 14 performed a straightforward extraction of anthocyanin pH indicators from Clitoria ternatea with hot water. Students were able to use this indicator and its vast range of colors to compare the acidity and basicity of different household solutions. Most responses recorded show that students used reasoning from the indicator and a subsequent chemical reaction to correctly differentiate acids from bases and compare their strengths. Overall, this activity's application of non-toxic and easily accessible indicators from the butterfly pea flower assisted in introducing young students to various concepts in acid-base chemistry, including acid/base strength and pH, solute dissolution, neutralization reactions, and qualitative analysis.more » « less

Reaction mechanisms are a difficult and foundational topic students encounter in organic chemistry. Consequently, students often memorize when attempting to learn the array of organic reactions. While interventions have been offered to encourage mechanistic reasoning as an alternative approach, a deeper struggle pertaining to students’ comprehension of the underlying chemical principles driving reaction mechanisms is still prevalent. In this study, electrostatic potential maps (EPMs) were explored as a tool students could use to reason with some of these principles to predict and explain the outcomes of a reaction. Through semistructured interviews, 19 students’ sense-making strategies were recorded and analyzed to uncover how they used the features of EPMs with concealed atomic identities and how they reconciled their answers once the identities were made explicit. Analysis revealed that the absence of atomic identities generated approaches centered around electron densities and their utility in predicting reaction mechanisms and outcomes. As the atomic identities were revealed, the majority of participants reverted to memorized mechanisms, while six participants attempted to relate the atomic identities to the interactions of the electron densities. These findings suggest utility in implementing EPMs in the organic chemistry curriculum and offer a feasible intervention to promote sense-making when students reason with organic reactions.more » « less

Instructional materials in organic chemistry include a wide variety of representations, such as chemical formulas, line-angle diagrams, ball-and-stick diagrams, and electrostatic potential maps (EPMs). Students tend to focus on explicit features of a representation while they are reasoning about chemical concepts. This study examined the affordances of electrostatic potential maps in students’ approaches when the maps were integrated into four foundational organic chemistry problems using an experimental design approach. First-semester organic chemistry students were surveyed from two different institutions, where they made predictions and explained their reasoning behind identifying an electrophilic site, predicting the product, selecting the faster reaction, and classifying a mechanism. Students were randomly assigned to one of four surveys that differed by the representation they were given for the prompts: chemical formula, line-angle diagram, ball-and-stick diagram, and EPM. Responses from students with EPMs were analyzed and compared to responses from students with the non-EPM representations. Results indicated that students with EPMs had higher performance depending on the problem. They were also more likely to cite electronic features such as electron density, nucleophilicity, etc., and were more likely to use causal reasoning in their explanations. This study offers evidence in support of affordances of EPMs in promoting students’ use of electronic features and causal reasoning. This evidence adds to the chemistry education literature by offering a potential means for promoting students’ use of electronic features and causal reasoning by incorporating EPMs into assessment items. Implications for instruction include using EPMs in both instruction and assessment as a tool to help students build skills around invoking electrostatics and causal reasoning to solve problems in organic chemistry.more » « less

Abstract BackgroundThis study investigates undergraduate STEM students’ interpretation of quantities and quantitative relationships on graphical representations in biology (population growth) and chemistry (titration) contexts. Interviews (n = 15) were conducted to explore the interplay between students’ covariational reasoning skills and their use of disciplinary knowledge to form mental images during graphical interpretation. ResultsOur findings suggest that disciplinary knowledge plays an important role in students’ ability to interpret scientific graphs. Interviews revealed that using disciplinary knowledge to form mental images of represented quantities may enhance students’ covariational reasoning abilities, while lacking it may hinder more sophisticated covariational reasoning. Detailed descriptions of four students representing contrasting cases are analyzed, showing how mental imagery supports richer graphic sense-making. ConclusionsIn the cases examined here, students who have a deep understanding of the disciplinary concepts behind the graphs are better able to make accurate interpretations and predictions. These findings have implications for science education, as they suggest instructors should focus on helping students to develop a deep understanding of disciplinary knowledge in order to improve their ability to interpret scientific graphs.more » « less
