My Personal Zoo Biology Activity

(View Complete Item Description)

This individual or group activity involves reading about the human microbiome, followed by explorations at University of Utah's Genetic Science Learning Center website. It was developed by Ryan Chabarria, Lone Star College- Kingwood; Jennifer Kneafsey, Tulsa Community College; Catherine Parmiter, Estrella Mountain Community College; Natalie Russell, Tarrant County College; and Andrew Tag, Texas A&M University.

OpenStax Chemistry: Flipped Classroom Reading Guides for General Chemistry (1st semester)

(View Complete Item Description)

Here you can find reading guides that were created by Montgomery College faculty for undergraduate general chemistry students to use to guide their reading of OpenStax Chemistry. These guides are closely aligned with chapters 1-11 and were designed for use in the first semester sequence of general chemistry. They can be used in a flipped-style classroom where students complete them before the lecture. Or they can be used to reinforce important topics learned in class. Each study guide has fill-in-the blank style questions, as well as links to videos where similar problems are worked through. Finally, suggested practice problems relevant to the topic of each study guide are listed at the end.

Ion-Exchange Chromatography

(View Complete Item Description)

We now know how to analyze pure compounds, but what if we have a mixture? Spectrophometry becomes quite complex when dealing with multiple species of compounds at once. In order to purify a compound we can separate if from a mixture based on its intrinsic chemical properties. Remember that fluorescein is negatively charged at a pH above pKa of the carboxyl group. We can take advantage of this fact and use its attraction to positive charges to separate it from other molecules. In ion-exchange chromatography, we will use a stationary phase with a positive charge, allowing negatively charged molecules to bind and positively charged species to flow through. We can then disrupt this interaction and retrieve our now-purified molecule, and use spectrophotometric analysis of our purified fractions to determine how well we were able to separate our molecules.

Here you can find reading guides that were created by Montgomery College faculty for undergraduate general chemistry students to use to guide their reading of OpenStax Chemistry. These guides are closely aligned with chapters 12-17 and 21 and were designed for use in the second semester sequence of general chemistry. They can be used in a flipped-style classroom where students complete them before the lecture. Or they can be used to reinforce important topics learned in class. Each study guide has fill-in-the blank style questions, and many have links to videos where similar problems are worked through. Finally, suggested practice problems relevant to the topic of each study guide are listed at the end.

ims-compliant zip file to upload to d2l (aka brightspace)

(View Complete Item Description)

I've converted the collection.xml file in the zipped version of OpenStax Chemistry v 12.1 https://cnx.org/exports/85abf193-2bd2-4908-8563-90b8a7ac8df6@12.1.zip/chemistry-12.1.zip to an imsmanifest.xml file so that one can import the whole book into D2L (Brightspace). Attached here is the imsmanifest.xml file alone. I don't know a lot about IMS compliance, but I think this imsmanifest.xml file could work for other LMSs as well. Please let me know if it does, or if you have other ways of importing the textbook to a LMS. I have also "prettied up" the html files in the zipped version of OpenStax Chemistry v12.1 by: - removing the path for the images, - using <details></details> for objectives, summaries and solutions, and - creating a .css file which takes advantage of the various environments defined in the .html file That new zip file is attached. Finally, I'm also attaching the perl script that I used to change the .html files, in case you want to make systemic changes to what I did or try something else.

Google Translate

(View Complete Item Description)

I used Google Translate to convert chapters of the US History OpenStax textbook to languages other than English by following these steps using Adobe Acrobat 9 Pro: 1. download the .pdf 2. Open in Adobe Acrobat 9 Pro (or other program that allows altering a .pdf file) 3. Under "Document", select "Extract" then identify the pages (assigned by Adobe, not the textbook) to extract. The file should be about 1/2 of a chapter to submit to Google Translate, otherwise it's too large. 4. Save the extracted file under a new name. 5. Go to translate.google.com and: a) select the language to translate to; b) click on "Translate a whole document", then upload the extracted chapter portion. 6. The translation appears as a page in the browser (I use Google Chrome) 7. Right click on the page and "Save as" on your computer (html file). 8. Upload to your LMS or other website, or email to the target student(s). The page will open in their browser. Although it's good for international students to learn and practice English in a formal setting, I feel it's unfair to test them on a subject they are completely unfamiliar with in a language they may not understand perfectly - double whammy! Translating can help even the playing field.
