Animations

To learn reaction mechanisms in organic chemistry students must understand organic chemistry’s symbolism, make connections between many abstract concepts, and visualize the invisible molecular world. However, the static models that educators use to describe reaction mechanisms poorly represent the dynamic nature of chemistry at the molecular level, where molecules are in constant motion. Animations of organic reaction mechanisms can bring to life the information embedded in these traditional, static representations.

The new organic chemistry curriculum at uOttawa and our online learning platform orgchem101.com use Organic ChemWare animations, created using best practices from the visualization literature. We are investigating how these animations affect student learning at the behavioural and neurological level. To do this, we are conducting studies to compare how static and animated representations of organic chemistry reactions are experienced by the students using eye-tracking technology, and also how they affect patterns of brain activity. In particular, we are interested in how resting state brain activity can predispose an individual’s problem solving abilities and capacity for learning. This mix of neuroscience and educational research allows us to investigate complex questions and will help us improve the quality and effectiveness of animations as learning tools for organic chemistry.


Flipped Classrooms

I teach most courses in a flipped  (aka inverted) format.  In a flipped course, content that is traditionally delivered in class is moved online, and problem-solving and other learning activities take place in class.  For these courses, the lectures are now online and are broken up in short video segments.  In-class time is dedicated to problem solving and figuring out more complex topics.  Our research found that a flipped classroom format significantly increased students' academic success in the course as well as significantly decreased the withdrawal and failure rates.

Improving Chemistry Education

Here are some other things we've worked on:


Online Learning Tools (the study of student learning)

 
 

OrgChem101 is a website that was created to help students learn organic chemistry’s language and provide students with the tools to help them better interpret organic reaction mechanisms as well as improve their metacognitive skill. OrgChem101 is free for anyone to use, and includes three modules: Organic Nomenclature, Organic Mechanisms, and Acid-Base Reactions.

Organic chemistry nomenclature

The Organic Nomenclature module is a FREE, bilingual, online, interactive learning tool designed to help students learn organic chemistry nomenclature. With this learning tool, students can draw organic molecules, name organic molecules, and identify key functional groups. There are hints to guide students along the way. Best of all, we describe the relevance of these molecules in our everyday lives! Here’s an article about the project written by Tyler Irving for the Canadian Chemical News (January 2012 issue): ACCN article.pdf and a more recent one: Organic chemistry students get online support for knowledge gap. ACCN, July/Aug 2014 issue, page 42.

organic reaction mechanisms

The purpose of the Organic Reaction Mechanisms module is to provide students with an online interactive resource in learning organic chemistry concepts. Currently, eye-tracking studies are working to investigate students' experiences using OrgChem101.

Organic Chemistry Curriculum

new organic chemistry curriculum

We developed a new organic curriculum at uOttawa that we have been teaching since 2011. We reorganized the reactions we teach so that they are organized by their governing mechanism. The goal is to help students identify and predict patterns and principles of reactivity rather than memorize.

current research

The organic chemistry curriculum at the University of Ottawa has been redesigned to incorporate a patterns-of-mechanisms model in place of a functional group one. To reflect and expand on this change, we are developing an evaluation strategy that encompasses the entire organic chemistry curriculum. The first step in establishing this framework was to subdivide the curriculum into the intended, enacted, and achieved curricula. To evaluate the intended curriculum, we are using fine- and coarse-grained learning outcomes to assess intra- and inter-course alignment and evaluating the learning outcomes for their potential to elicit science practices, crosscutting concepts, and disciplinary core ideas. We are evaluating the enacted curriculum by investigating which learning outcomes have been taught, practiced, and assessed in each course. Finally, we are employing the New World Kirkpatrick Model to evaluate the achieved curriculum—to establish evidence for student success in attaining and applying the learning outcomes. Investigating the connections between all three parts composing the framework will directly inform testable curricular modifications that will be implemented and evaluated in future years.

Organic Chemistry's Language

There are currently two projects related to the evaluation of the patterns of mechanisms curriculum at uOttawa. One project is studying how students interpret and use the language of mechanisms having learned the symbolism, but before learning specific reactions. The second project is investigating how students organize their knowledge of organic reactions.

patterns of reactions research

The organic chemistry curriculum at uOttawa is taught based on the governing pattern of mechanism. One of the goals of this organization is to help students to be able to make connections between reactions with different structural features but similar mechanisms. If students are able to identify mechanistic patterns between reactions, then the need for memorizing individual reactions is reduced. Although the curriculum is organized by pattern of mechanism, we need to collect evidence for how students are perceiving (or not) connections between organic reactions. We have developed a card sort task to explore how students are organizing their knowledge of organic reactions. The results from this study will provide evidence for how to design instruction to help students be able to identify mechanistic patterns across organic reactions.

SSHRC Project

Students studying organic chemistry must learn to understand the macroscopic and submicroscopic levels of chemistry, both of which are communicated through a third symbolic level comprised of symbols and representations, which is organic chemistry’s language. More specifically, organic chemists use curved arrows as a form of symbolism to analyze and explain electron movement at a molecular level.

The SSHRC study employs eye-tracking methods to investigate how students and experts “read” organic chemistry’s language. Additionally, since the new curriculum at the University of Ottawa explicitly teaches organic chemistry’s language before concepts and reactions, this study aims to investigate, through eye-tracking, the effect on cognitive load of learning chemistry’s language before concepts. The SSHRC study also aims to investigate, through interviews, how students categorize organic reaction mechanisms by considering how they choose to associate new information with existing knowledge. The results from the SSHRC study will provide insight into how explicitly learning organic chemistry’s language affects students’ attention, cognitive load, and meaningful learning.

Organic Synthesis

The cognitive domain of Bloom’s taxonomy (describes six orders of learning in the form of a pyramid, in which remembering is at the bottom and creating (something new) is at the top. The higher orders of learning require advanced skills such as analysis and problem-solving, as well as incorporating the lower level skills. Retrosynthetic analysis and synthesis require higher order thinking skills and constitute challenges in learning. We are studying how chemistry students learn those higher order skills and the effectiveness of in- and out-of-class teaching & learning activities. One main goal is to help students improve their higher order thinking skills through those targeted learning activities.

We're studying students' strategies and skills in solving organic synthesis problems. We've also developed learning activities that can be used in large or small classes to help students learn those skills. Check out Nik's recent video about our work:
