In part I of this blog series, we explored why Pete, Melanie, and I believe critical thinking is a vital skill that students should learn while earning an undergraduate degree. We also explained our hypothesis in which we believe that the utilization of the flipped teaching model allows us to incorporate more active learning and blended learning techniques that can enable our students to further practice and hone those skills associated with critical thinking. In this video, we explain both the differences in our three classes and how we incorporate flipped teaching; as well as our study methodology and the tools we utilized to assess whether or not flipped teaching promotes critical thinking within our students.
If you have been following along with me during my flipping journey, then you are aware of a study in which two colleagues (Dr. Melanie Styers and Dr. Pete Van Zandt) and I wanted to assess whether or not flipped teaching promoted critical thinking within our students... but instead of me writing about it, we thought, in good flipped teaching manner, we would make some short videos to describe our project.. here is video one which describes who we are, and why we think critical thinking is important:
Please stay tuned for part II, which describes the mechanics of our project.
As Chemistry faculty in a small private liberal arts college just miles from a medical school that ranks 22nd in the nation, I have noticed that 90% of my chemistry and biology majors are pre-health. When I accepted my position at BSC, I was asked to continue the Medicinal Chemistry course (CH418) within our department. In my previous experience as a student I have found that a traditional MedChem course consisted mainly of the in depth analysis of various organic chemistry reaction mechanisms, sprinkled with a little discussion on drug targets, drug sources and pharmacokinetics. Although I believe the traditional Medicinal Chemistry course is valuable for graduate school bound chemistry majors, I wanted to focus on some different learning goals. The following learning goals are ones that I felt would benefit my pre-health majors as they continued on to become nurses, doctors, physical therapists and dentists. And of course, still sticking to my flipped style of teaching, this course is designed very much around active learning, discussion techniques with pre-assigned readings from the text and peer-reviewed literature.
From initial hit to market, a new compound has a long and arduous path that almost everyone in our society takes for granted. The number of various agencies, individuals and monies involved to develop safer and therapeutically more effective drugs is quite astounding. One day my students will be doctors prescribing these medications to patients; or nurses and pharmacists packaging, administering, delivering and counseling on these medications; and I want to ensure that they (1) understand the drug's pathway to the market, (2) understand why the drug is effective and how it works, (3) are able to evaluate and relay the pertinent information of that drug to a wide range of patients and (3) are able to effectively answer patient questions. Currently, our society is plagued with an ever increasing amount of scientific illiteracy and public distrust in modern medicine, our emerging generation of health professionals will be at the forefront of this battle, and we as their instructors and teachers need to equip them with sufficient knowledge and skills to be effective in this battle.
In order to approach this learning goal, I have designed CH418 as a discussion based class with pre-meeting reading assignments. Our typical class meeting utilizes a variety of active learning techniques such as "Think-Pair-Share", POGIL, case studies, and "2-minute papers" in order to facilitate classroom discussions. At the end of class, I will sometimes assign a discussion board reflection to continue our conversation. For example, after creating a timeline of events for a drug's path to the market through classroom discussion, I then assigned each student a different stakeholder's role (e.g. Chemical Engineer, FDA Agent, Patent Attorney, Clinician, or Patient) and had them write a short summary of that stakeholder's role and responsibilities and a reflection of how interactions with that stakeholder may impact their own lives or careers. These reflections were then posted on our course management page and students were encouraged to read and respond to each other's posts.
In order to measure students' success in reaching this learning goal, students will be given 3 take home exams consisting of short answer and multiple choice for content testing, and short essay questions to further explore their understanding and ability to evaluate, apply and communicate complex processes. In addition, I also utilize Sapling Online Learning to create weekly online homework assignments, as Sapling does not yet have a Medicinal Chemistry unit, I am working with my TA to help design a bank of questions.
Overall, I have arranged a guest speaker series bringing in 5 different professionals through out the semester, giving my students the opportunity to learn directly from the source, make new network connections, and discuss their questions with someone other than me. To see the schedule of speakers for Spring 2015, click here.
To prepare my students for our guest speakers, I will assign one or two published peer-reviewed articles authored or recommended by our speakers and then have them post at least one question to our course message board prior to the event. Often questions in the take home exams will arise from these talks or assigned readings.
In order to further understanding (and allow me another opportunity to assess their learning) students work on a literature review paper and prepare an oral presentation detailing the path to the market of a drug of their choosing. This project is assigned at the beginning of the semester and students are given detailed guidelines, rubrics and a timetable of assignments to follow and opportunities for peer review in order to help keep them on track. During the last week of class, students then give oral presentations summarizing their findings to the rest of the class, and questions from these presentations do show up in the final take home exam.
Although this class strays from the path of a traditional medicinal chemistry course, it does so to service my non-traditional students. In this course students are able to utilize a variety of resources from peer reviewed literature, texts, and guest speakers to explore in-depth current topics related to medicinal chemistry. So far, the students seem to enjoy the course, they have found the guest speakers engaging, and our classroom discussions have been pretty productive! I will report back at the end of the term how the course reviews go! Till then, happy studies everyone!
No, no, no.. I am not verbally expressing dismay with Biochemistry, I am talking about a teaching method that has gained momentum in the STEM disciplines recently: Flipping the class. Instead of spending class time lecturing, students are given lecture materials and reading assignments to complete on their own time before class. This method allows class time can be spent working on practice problems, group learning activities or discussions. Since this was my first experience with a full lecture course of my own, and because I prefer active learning techniques, I decided "why the heck not!!" and dove head first into creating a flipped biochemistry course. The major advantages I have found for flipping the class is that we, as a class, now have time to delve deeper into the material, allowing my students to further develop their critical thinking, communication and creativity skills necessary for developing as life long learners. However, as rewarding as the results of a flipped classroom may be... there are still some major challenges... a flipped class is hard work (on both the instructor and the student)! So I wanted to spend some time describing the challenges of a flipped class, my method for flipping an advanced undergraduate chemistry course like biochemistry, and resources that can help you flip your own course.
Pre-Class: The Video Lecture
During Class: Group Learning
Because this is my first year teaching biochemistry, as well as my first year doing a flipped class, I have been devoting most of my time on the development of lectures and videos, and not on developing my own group learning activities. Thankfully, there are a number of great case studies, and group-learning activities already developed for Biochemistry. For this semester, I have been utilizing the POGIL workbook "Foundations of Biochemistry" and so far have been very pleased with both the level of challenge and the amount of time to complete the activities ( about 45 minutes). For units that do not match well to an activity in the biochemistry POGIL, I often turn to case studies provided by the textbook publisher or from the NSF Case Study Collection. As the semester continues, should I find an exceptionally good activity or design one, I will share it here!
After Class : Homework
To help reinforce the material from the text, lecture and group learning activities, I also offer my students weekly interactive homework assignments using Sapling Learning. This wonderful tool was first introduced to me by my colleague, Dr. Melanie Styers from the Department of Biology at BSC, who also utilizes this website for her Biochemistry course. At Sapling, instructors are able to design homework or practice assignments, as well as quizzes or exams from a bank of questions ranging in difficulty developed from the class' text book material by educational professionals. The instructor can set the point value and distribution as well as the number of times students can attempt a problem (and whether there is a point penalty for each attempt). Sapling also provides a range of review exercises, tutorials, hints, and answer solutions. Each instructor is paired with either a masters or PhD level teaching assistant with a background in the course material who can assist in developing the material as well. In addition to helping students further understand the material, students are able to access their course materials for as long as they are a student, allowing them to utilize this tool for professional school entrance exams such as the MCAT,
In addition to online homework, I also utilize current media or interesting studies related to the current unit's material to spur online discussions. And I have to say, these students do exceptionally well discussing topics such as the increased rate of the ebola virus genetic mutations, and the effect of climate change on specific ecosystems at the cellular level.
So far, I have really enjoyed this method of teaching. It has allowed me to cover the immense amount of material required for an undergraduate Biochemistry course, while at the same time allowing my students to further explore these topics much as graduate students would in a more advance course. That is not to say there hasn't been any push back, the students do realize they are working harder and doing more. However, my students are starting to realizing that instead of being challenged by the material for the first time in an exam, they are instead being challenged by the material for the first time while working in groups of their peers with unlimited resources at their hands. By learning how to solve real world simulations, delving deeper into the material, and learning how to work with their peers, my students are quickly gaining not only a working knowledge and understanding of Biochemistry, but also the skills necessary for becoming life long learners.
Some other bits of advice... don't be so hard on yourself, even in traditional lectures, the class doesn't always run as according to plan. You may run out of time, an activity may not have worked as well as you hoped, or you may finish waaaay to early and didn't prepare. So first, keep a teaching journal and immediately following class go back and right down what worked and what you could change for next year. If you finish early, never under estimate the power of classroom discussions, keep a few think-pair share questions on hand, a good one is to have students jot down 3 things they already know about the next unit's material, or have them come up with 3 possible exam questions. And always remember, if your students watched the lecture videos and read their assignments, then even if the day's group activity fail short of expectations, it was still above and beyond what they would have gotten from a traditional course.
The first day of class sets the tone for the entire semester, this same principle can also be applied for the first day of a project in industry. Commonly, on the first day of class students file in, excited knowing that it will be short class while they (sometimes) listen as the instructor goes over the syllabus, describes how the class works and expectations, so on and so on. Sometimes students will be able to introduce themselves, if class size and time permits, but usually its just a passive experience of watchful waiting till they are dismissed.
Hi, my name is.....
Last semester in my Current Research Methods in Chemistry course (CH201), I decided to break the ice utilizing more active learning techniques. After a brief, and I mean brief, introduction of myself, I had students introduce themselves with their name, major, and after school goals (grad school, med school, industry, etc). Because this class only consists of 10-15 students, this is easily do-able. For larger classes, this introduction could still be used utilizing current technology from polling software such as polleverywhere.com , clickers, and social whiteboards such as padlet.com.
Grouping it up!
After introductions, I went into a brief explanation of the course, why the course is important. A large portion of CH201's grade is based on a semester long group project so I take the time in this class meeting to set up groups. Now the instructor has a few ways in which students can be divided into groups such as allowing the students to form their own groups or assigning groups randomly. I decided to merge group formation with another active introduction technique : "mix to rank". Here, students had to form a line, ranking themselves based on their previous research experience from most experienced to least or none. Again, this is a technique easily employable in a small classroom size such as CH201, and allows students to talk and get to know about each other's previous research experience AND gets them up, out of their seat and moving after having to sit and listen to me drone on and on about the course syllabus for 15 minutes. Again, if you are in a larger class, you can use polling software or clickers to try and discern previous experience or knowledge. Once the students are ranked, I then have them count off 1 through 3 or 1 through 4 depending on class size. All the people with the same numbers are then in a group. This allows for an even distribution of research experience within the groups, so that each groups has someone with lots of experience, someone in the middle and someone with little or none.
Shhhhh. It's quiet time.
Now that we have groups formed, introductions made, and have gone over the syllabus and course expectations, it was time to get them thinking. WHAT... wait? You make students think on the first day of class? Yes, In class time is precious on the college campus, its the only time we as instructors have where we can focus on our students 100% without distraction of research, faculty, administration, etc. So I try to pack as much into each class as I can. Do I want to overload my students? No, so I try to employ as many active learning techniques so that the students can learn through guided activities without feeling overwhelmed or without getting bored from listening to me yammer on and on about the scientific method. In this activity to help teach students the elements of a good experiment, I employed "silent discussions". In this activity each group of students (formed previously from the "mix and rank" activity) are instructed to pick a team leader, handed a stack of post-it notes and sharpies, and are instructed to write words or phrases on at least 5 post-it notes per person that describe the elements of a good experiment. And they are to do this without saying one single word to each other. Once the words/phrases are written, students then arrange the notes on a whiteboard or wall into categories... again in complete silence. Once each group is satisfied with their groupings, the team leader is allowed to do one final rearrangement at his or her discretion, again without talking. In the end, the team leader from each group reads the words/phrases and explains why they are grouped together. This activity then naturally progressed into a whole group discussion about what makes a good experiment good, and got them thinking about what general elements or factors they need to consider in their upcoming research project. If this class size is too large or the course is online this activity can easily be adapted with virtual whiteboards such as padlet.com,
Reflect and Adapt
So now the students were so engrossed in our discussion that we didn't just run out of time, we ran over by 10 minutes before anyone realized. On the first day of class! That, to me was, a huge success. I was able to engage 15 freshman chemistry students for an ENTIRE hour (and 10 minutes) on the first day of class, got them talking to each other, sharing research experiences, discussing the scientific method and thinking about their future projects. At the end of class, I had students share and record their group's contact information (which ever they are comfortable giving) and sent them off on their way till next time!
Upon reflection of this class meeting, I have been pondering ways in which to adapt this course for an online environment. I believe everyone agrees that the undergraduate research experience is an invaluable aspect of college life, but those who are distance learners are at a serious disadvantage if they are unable to participate in research. In order to achieve this, I think i need to first reflect on each class day by day. To adapt the first day, we could hold a synchronous class through a platform like Blackboard Collaborate where students can still introduce themselves using video and audio feed just as we do in the face to face class. We can still share information about previous research experience, and even rank students with polling questions, and can even still form groups for classroom activities. The group project however may be difficult due to location barriers and each student may then have to do an individual project or if location allows, groups can form based on location. The "silent discussion" activity can still easily work on an online platform by utilizing either Blackboard's whiteboard in Collaborate or by using padlet.com. And then we can try to moderate discussions by "raising hands" so that not everyone talks at once and we just end up with noise and feedback.
