EARTH 501: CONTEMPORARY CONTROVERSIES IN THE EARTH SCIENCES (3 credits). Exploration of current areas of research in the Earth sciences.
This course will introduce you to a variety of topics from different disciplines within the Earth sciences, with the aim of piquing your interest in areas of current research being conducting by myself and my colleagues here at Penn State. I intend the subject matter and the rigor with which I treat it to be beyond the level found in typical secondary school or introductory college textbooks. However, this should not deter anyone who feels they have a limited science or math background! On the contrary, I have designed each unit to present both the cutting-edge science as well as the background a secondary student (or a teacher of secondary students) would need to place the cutting-edge research in context. Gaining an appreciation of how scientists choose the subjects they study and why certain topics elicit controversies is as fundamental to Earth science as the discovery of the facts themselves. The topics we are covering in EARTH 501 include subjects in which a consensus has recently been reached as well as scientific questions that are so far unanswered. You will learn the appropriate state-of-the-art scientific content relevant to each topic by performing basic data analysis (e.g., collection, interpretation and assessment) using publicly available data in order to complete the activities in each lesson. I have specifically designed the lessons with publicly available datasets precisely because I want you to be able to use the data and lessons from this course freely in any courses you teach.
EARTH 501 will be conducted entirely on the World Wide Web. There will be no set class meeting times, but you will be required to complete weekly assignments. There are 6 lessons that will be completed at a rate of approximately 2 or 3 weeks per lesson. Lesson learning activities will require background reading and discussion that outlines a current scientific problem or debate, the collection and manipulation of appropriate data, and the assessment of the results of this work. By doing this, you will simultaneously become familiar with the content as well as the practice of science. You will also participate in online discussions about how to teach this content to specific secondary school audiences. You will complete a capstone project in which you will construct a teaching plan based on the topic of your choice.
What I Expect of You
On average, most students spend eight hours per week working on course assignments. Your workload may be more or less depending on your prior experience with computing and the Web in general, and with geology in particular.
I have worked hard to make this the most effective and convenient educational experience possible. The Internet is still a novel learning environment, but in one sense it is no different than a traditional college class: how much and how well you learn is ultimately up to you. You will succeed if you are diligent about keeping up with the class schedule, and if you take advantage of opportunities to communicate with me, as well as with your fellow students.
Specific learning objectives for each lesson and project are detailed within each lesson.
At the successful completion of this course, students should be able to summarize current thinking on several specific areas of current research in the Earth sciences, collect and analyze data relevant to these topics, and formulate a plan to teach appropriate content from these topics to secondary school audiences.

If you have any questions about obtaining or activating your Penn State Access Account, please contact the World Campus.
EARTH 501 will rely upon a variety of methods to assess and evaluate student learning, including:
- Required participation in online discussion forums, so I can gauge your progress and ability to articulate key concepts. I will assign weekly readings and ask you to discuss and debate the significance of these readings within the larger framework of the current lesson's topic. The discussions will also be a venue for you to get help or give help when performing the data analyses.
- Data analyses and write-ups that require you to collect and interpret datasets.
- A capstone project that will be used to evaluate your knowledge and skills through the production of a learning module that you, in turn, will be able to use to teach course concepts to your own students.
You will earn a grade that reflects the extent to which you achieve the course learning objectives listed above. Grades are assigned by the percentage of possible points earned in each lesson's activities. Below is a breakdown of each lesson's value as a percentage of the total course grade.
|Lesson||Percentage of Grade|
(based on participation)
|Lessons 2–5 data analyses + papers||50%|
|Lessons 2–5 discussion participation||30%|
I will use the gradebook in Canvas to keep track of your grades. You can see your grades, too, by clicking the Grades link in this course's Canvas space. Overall course grades will be determined as follows. Percentages refer to the proportion of all possible points earned.
|X||Unsatisfactory (student did not participate)|
Below you will find a summary of the learning activities for this course and the associated time frames. This course is 12 weeks in length, beginning with an official orientation week. We will also have a week-long break, usually in between lessons 4 and 5. In the fall semester there will also be a break for the Thanksgiving holiday. I will make the actual dates of our schedule clear both in Canvas and in the lesson overview pages.
|Date||Weeks 2 & 3|
|Date||Weeks 4, 5 & 6|
|Date||Weeks 7, 8 & 9|
|Date||Weeks 10 & 11|
Plenty of students who have never taken an online course worry about feeling isolated. In fact, past experience shows that it is easier to feel isolated in a great big lecture hall where nobody wants to draw attention to themselves. This class is not enormous and you will find that regular participation in the discussion boards will not only make you part of the community of this course but will also allow you to organize your thoughts and logically process the science you'll be doing. I conceptualize the discussion forums the same way I do weekly lab meetings with grad students. Having to explain things to your peers is a great way to crystallize your own thinking about a topic. It is also the perfect platform for giving and receiving feedback about your scientific approach or your teaching approach.
Do the work on time
Please believe that I understand the time constraints placed on you. I have five kids, ranging in age from 20 years to 2 years. I know how hard it is to work, study, be a parent, and occasionally still try to stay up for a West Coast baseball game on TV. My suggestion is to treat this like a class that has actual hours, and to set aside specific periods of time each week to do the work, think, and participate in the discussions. If you find you are falling behind, do not silently suffer and try to rush through the work. You must let me know of any difficulties so that I can help you! Unforeseen emergencies excluded, my late policy is that you need to discuss with me any potential problems regarding being on time before assignments are due.
Don't lie, cheat, or step on people's feet
You are an adult. You are a graduate student. Cheating and plagiarizing is a waste of your time and mine. If you are unsure what constitutes cheating and plagiarizing, then please review our course policy on Academic Integrity located below.
I cannot overemphasize the importance of academic integrity. DO NOT copy and paste from unreferenced sources. Without exception: if you use a direct quote from any source, as part of any submitted assignment, the quote must be clearly noted and properly referenced.(In-line references are fine.)

In case of weather-related delays at the University, this online course will proceed as planned. Your instructor will inform you if there are any extenuating circumstances regarding content or activity due dates in the course due to weather delays. If you are affected by a weather-related emergency, please contact your instructor at the earliest possible time to make special arrangements.
Connect Online with Caution
Penn State is committed to educational access for all. Our students come from all walks of life and have diverse life experiences. As with any other online community, the lack of physical interaction in an online classroom can create a false sense of anonymity and security. While one can make new friends online, digital relationships can also be misleading. Good judgment and decision making are critical when choosing to disclose personal information with others whom you do not know.
If you are prevented from completing this course within the prescribed amount of time, it is possible to have the grade deferred with the concurrence of the instructor. To seek a deferred grade, you must submit a written request (by e-mail or U.S. post) to your instructor describing the reason(s) for the request. It is up to your instructor to determine whether or not you will be permitted to receive a deferred grade. If, for any reason, the course work for the deferred grade is not complete by the assigned time, a grade of "F" will be automatically entered on your transcript.
This course will be conducted entirely online. There will be no set class meeting times, but you will be required to complete assignments with specific due dates. Many of the assignments are open for multiple days. It is your responsibility to complete the work on time, which may require you to complete the work early if you plan to travel or participate in national holidays, religious observances, or University-approved activities.
If you need to request an exception due to a personal or medical emergency, contact the instructor directly as soon as you are able. The instructor's ability to accommodate you is dependent on the earliest possible notification. Such requests will be considered on a case-by-case basis.
Please note that the specifics of this Course Syllabus can be changed at any time, and you will be responsible for abiding by any such changes. All changes will be communicated with you via e-mail, course announcement and/or course discussion forum.
