Lewis structures are fundamental to learning chemistry, yet many students struggle develop a complex understanding of its meaning and uses. Writing-to-Learn supports in developing deeper conceptual the topic, making it an ideal pedagogy apply student structures. One difficulty often associated with classroom writing is capacity instructors provide feedback each on their written work; however, this practical constraint can be mitigated through incorporating peer review. Peer review revision...
Generating a testable hypothesis is necessary skill for engaging in science, requiring both general reasoning skills and specific content knowledge of the phenomenon being investigated. While many students have developing hypotheses science context, it can be challenging to apply these areas where phenomena studied are unobservable, such as problems organic chemistry. experiments that expected chemistry teaching laboratories. Students benefit from receiving real-time feedback support this...
Nuclear magnetic resonance (NMR) spectroscopy is an essential analytical tool in chemistry, and the technique routinely included as a topic across undergraduate chemistry curriculum. As result of NMR's importance, classroom instruction this has received considerable attention education research. However, little known about instructors’ knowledge for teaching topic. In order to better understand knowledge, we investigated topic-specific pedagogical content 1 H NMR among 20 assistants at large...
Promoting students’ ability to engage in discipline-specific practices is a central goal of chemistry education. Yet if instruction meaningfully foster such ability, we must first understand reasoning during these practices. By characterizing constraints on reasoning, can design that targets this constrained and ultimately promotes more sophisticated ways thinking. For study, investigated used by 18 organic students at large university the United States as they evaluated success chemical...
Instrumentation plays a critical, ubiquitous role in modern chemistry. The undergraduate chemistry curriculum must therefore cultivate students' ability to investigate chemical phenomena via relevant instruments. instructional laboratory serves as the primary context which undergraduates learn about instrumentation, where use of instruments these settings is requisite meaningful learning. However, little known what are incorporated and level hands-on experience. Also, prior research points...
A national survey of chemists (n = 174) explored the self-reported format and focus postsecondary inorganic chemistry instructional laboratory curricula. Multiple course formats were observed, including stand-alone courses, instruction as a component multidisciplinary course, absence an experience. Additionally, types synthetic, characterization, purification methods, well professional skills addressed in surveyed varied greatly. The results this work have direct implications "current state...
Over a decade has passed since faculty members’ goals for the undergraduate chemistry instructional laboratory were first investigated on large, national scale in United States. This study revisits these goals, using data from 2022 survey of members States ( n = 521) to investigate current objectives, including how those vary with course, institutional context, and receipt funding improving courses. A modified version Faculty Goals Undergraduate Chemistry Laboratory Instrument was used...
Faculty members in STEM report numerous motivators and barriers to adopting evidence-based instructional practices (EBIPs), yet the degree which these factors are associated with EBIP adoption postsecondary chemistry courses is unclear. The role of departmental climate around teaching driving or hindering particularly unresolved. This study investigates, via a national survey faculty (n = 983), various other courses. Measures were obtained using modified version Departmental Climate Teaching...
Advancements in organic chemistry depend upon chemists' ability to interpret NMR spectra, though research demonstrates that cultivating such proficiency requires years of graduate-level study. The community thus needs insight into how this expertise develops expedite learning among its newest members. This study investigated undergraduate and doctoral students' understanding information processing during the interpretation 1H spectra complementary IR spectra. Eighteen seven students...
Course-based undergraduate research experiences (CUREs) are a promising approach for incorporating inquiry-based instruction into the chemistry laboratory curriculum. This study used data from national survey of inorganic faculty members (n = 142) to investigate CURE implementation in instructional laboratory. Results indicate that who implement CUREs place greater emphasis on distinct set goals when compared do not CUREs. was further associated with range and departmental characteristics,...
Nuclear magnetic resonance (NMR) spectra are among the most common visualizations used by chemists in both academic and industrial settings, where they serve as representations of submicroscopic entities tools that support social discourse. The ability to use words communicate about features within NMR is thus an essential aspect chemists' representational competence. Collectively, these constitute a highly specialized language specific this technique. To adequately prepare chemists,...
Proton nuclear magnetic resonance ( 1 H NMR) spectroscopy is an essential characterization tool for organic chemists widely taught in the undergraduate chemistry curricula. Previous work has focused on how students advance from novice to expert interpreting NMR spectra. However, we need know more about within We sought characterize instructors’ topic-specific pedagogical content knowledge (PCK) teaching as a starting point investigate taught. Participants multiple institutions—six...
Course-based undergraduate research experiences (CUREs) integrate authentic into chemistry laboratories, introducing students to while simultaneously reinforcing fundamental concepts. Despite their ubiquitous nature in bioanalytical research, few CUREs have been published applying the techniques of separations, spectroscopy, quantification, and mass spectrometry. To engage learning these increasingly essential techniques, we designed implemented a semester-long project-based course centered...
A national survey on chemistry instructional laboratories was administered to faculty members at four-year postsecondary institutions in the United States for purpose of exploring levels inquiry-based instruction implemented laboratory courses. Respondents were asked rate level choice their students had deciding six key characteristics experiments used course ( e.g. , what research questions explore); more choices get make, experience. MANOVA and post hoc analyses suggest that there are...
Abstract. The FORCAsT (FORest Canopy Atmosphere Transfer) model version 1.0 is updated to 2.0 by implementing five major changes, including (1) a change the operator splitting, separating chemistry from emission and dry deposition, which reduces run time of gas-phase 70 % produces more realistic in-canopy profile for isoprene; (2) modification eddy diffusivity parameterization produce greater vertical mixing in boundary layer, ameliorates unrealistic simulated end-of-day peaks isoprene under...
Despite institutional reform efforts to increase use of evidence-based instructional practices (EBIPs) in undergraduate chemistry and STEM courses, didactic lecture remains the predominant mode instruction. Research inform these initiatives routinely focuses on drivers barriers EBIP adoption, with recent work investigating factors associated faculty members’ cooperative adoption EBIPs from five disciplines including chemistry. To understand role specific within education across a broad set...
