Mineralogy

This course is an introduction to fundamental mineralogy and mineralogical principles.

The exercises linked to the classes below are all cooperative learning exercises, except for the Private Mineral Project. Most of the exercises are started during class but require groups to continue working on them outside of normal class time. Materials and mineral samples used in the activities can be altered to correlate with what is available to each institute.

Downloadable files of the exercise assignments, problem answers, and instructor's notes can be obtained for most of the exercises by clicking on appropriate links on the exercise pages.

Comments for Students on the First Day of Class

How Class is Taught

This class is taught in a studio format. Studio classrooms may have many different manifestations but all share common elements. They involve longer, fewer, class sessions with focused, intense, student activity. Any disconnect between laboratory and lecture time is absent because lab and lecture are combined. Lectures are de-emphasized or eliminated altogether so students can work on projects instead, generally in groups.

Why Teach This Way?

Many studies have shown that students learn best by doing things (active learning) instead of just listening (passive learning). Additionally, it is well known that most students learn best when they learn in groups (cooperative/collaborative learning). Studio classrooms are centered around active and group learning. The interactive classroom helps students learn the standard class content. Additionally, it promotes holistic skills, including thinking, inquiry, creativity and reflection.

Spiral Learning

This class also involves spiral learning. That means we will cover topics more than once, returning to them several times and in different contexts. The basic order of topics follows the textbook but we will discuss the key principles many times.

Working in Groups

Most of the work you do this semester will be done in groups. The instructor and TA will assign the groups; they will change periodically. All members of a group are responsible for seeing that assignments get completed. For some assignments, a single group report will be adequate. For others, each person must write their own report.

Reading Assignments: Text Books and Handouts

Two texts are used:
  1. Perkins, 2002, Mineralogy, Prentice Hall
  2. Perkins and Henke, 2004, Minerals in Thin Section, Prentice Hall
In addition, the instructor will provide many handouts and supplemental information pertinent to specific class activities. You are expected to read them on your own. The instructor and TA will NOT give lectures that just repeat what is in the books. Instead, they will talk about things that you identify as being areas of confusion.

Quizzes

We will have many quizzes this semester. They are meant, primarily, to be learning experiences. Often, you will take the quiz individually and then get together with other students and take it again. Individual and group grades will be averaged.

Work Time In and Out of Class

Although class is scheduled to meet in 3 hour blocks, there will be quite a bit of variation. During a typical class period, we will have several things going on. Different groups will be doing different things. Some days you may get done early. But, if you fall behind, it will be very difficult to catch up. Also, many of the projects we will be doing require you to put in time beyond normal class hours. This is especially necessary when you need to use the X-ray machine, photographic equipment, and other gizmos.

Portfolios

This semester, you must keep a three ring binder portfolio that includes all your work for this class. You will hand in most assignments by handing in your portfolio. Periodically the TA or instructor will review your portfolio with you to make sure it is readable, complete and well organized. From time to time, we will ask you to go back through your portfolio and reflect on what you have done and what you have learned. During this process you will evaluate the merit/effectiveness of the various activities, making suggestions for things we could do that would help promote better learning. You will also discuss your learning: what worked, what did not work, and why. You will be able to use your portfolios for most parts of your exams!

Keeping Notes

Some projects are complicated and several experiments require a lot of measurement and calculation. It is absolutely necessary to keep good notes or risk getting very confused. We will talk more about this as we go on, but keep this rule in mind while working in the lab: write down everything and keep good portfolio notes! One common source of mistakes is weighing errors. So, everything that is weighed needs to be weighed twice, by two separate people. There will be a book by the scale. Write down what is weighed, how much it weighs, and then initial it. Then get someone else to repeat the weighing and put down their initials.

Assessment

Students will be graded based on:
  • group projects
  • class portfolios
  • a semester long "private mineral" project
  • several exams
