There are ways to cut cheating by students

Last spring, there was wide spread cheating in a Harvard course titled “Government 1130: Introduction to Congress.” Taking this course was reputedly a way to “an easy A.”

The course grade was based entirely on four take home exams, each counting 25 percent.

The students were instructed not to collaborate (work together) in answering their questions.

There were indications that 125 students (out of 279) cheated (collaborated or copied) in this course.

Harvard University is now considering an honor code , a pledge against lying, cheating and stealing that each student will sign.

Is this problem unique to Harvard? Donald McCabe, a Rutgers University professor has been studying college students’ attitude toward cheating for several decades.

In his 2010-2011 survey of students at many different schools, 62 percent of undergraduate students admit to either cheating on tests or on submitted papers.

I want to add that surveys of college students reveal that the average student (at many different schools) spends only 11 hours of study a week outside of his/her classes.

This is quite different from the usual faculty recommendation that students spend two hours a week in studying per week for each hour spent in their classes. Without adequate preparation (outside study), many students will be tempted to cheat in their courses.

First, as a college teacher for a number of decades, I want to point out some obvious things.

It is folly for any professor to rely on take home tests for all of a student’s grade.

Most college teachers rely on papers, quizzes in class, tests in class, and student participation (a mix of assessment tools) to determine a student’s grade.

There are different kinds of skills and talents each student brings to a class and student evaluation should tap into what students can do.

It was reported that the exam questions were unrelated to the professor’s class presentations. This shows poor teaching technique.

It’s not that exams should closely follow the class presentations, but what’s done in class should connect with the course objectives, that the exam questions should reflect.   

Over the years, I have developed some teaching techniques that reduce the amount of cheating in my classes.

The in-class tests vary in the sequence of questions so a student looking at another student’s test will not see the same items. Also the questions are not numbered so I can rearrange them easily.

For multiple choice questions, I don’t use the standard A), B), C) and D) as choices. The response identifiers are usually two letters, as AT = all true, LA = lacks atmosphere, etc.

For the fill-in the blank questions, at the end I supply a BANK of possibly correct answers that a student may pick from.

I tell the students that they should use their own answers; relying on the BANK should be a last resort.

I also put into this BANK some formulae that may be relevant to answering some questions and problems.    

As a way of preparing a student for my tests, I post a sample test that they can view. I tell them these test items are not those from the actual test but utilize the same kind of thinking.

I also post a study guide for each test that encourages the students to go back through the chapters and try to answer key questions.

Once again, the study guide questions are not actual test questions; but by answering these questions, the students will be testing their understanding of topics.

SKY SIGHTS THIS WEEK: Late yesterday, the moon swung from the morning to the evening side of the sun (new moon).

By Tuesday, a very slender crescent moon should be seen low in the western dusk as it begins to get dark (about 8:15 p.m.). Nearby the moon that evening will be the planet Saturn.

On Wednesday at dusk, the moon will be close to the planet Mars. Both planets are rather dull, being on the far side of their orbits.

This Saturday, the moon will appear half full. This is the best phase or shape to see the moon’s craters and mountain ranges.

The Cumberland Astronomy Club will meet this Sept. 21 at the LaVale Public Library just off the National Highway.

  • It’s hotter here than in D.C. or Baltimore

    At this time of the year, the weather is a frequent subject of conversation, particularly the temperatures. We are now in the “Dog Days,” usually the hottest days of the year. The term comes from our sun appearing to be near the “Dog Star” (Sirius) and the “Little Dog Star” (Procyon). In reality, the sun is now about 94.5 million miles away while Sirius is 8.6 light years away with Procyon at 11 light years distance. Sunlight takes only 507 seconds to reach us, while the two dog stars’ light takes about a decade to travel to our eyes. So our sun is in the same direction (but not distance) as these two bright winter evening stars.

  • A long and winding road faces our food

    Last week’s column dealt with organs you can do without, our DNA (molecular blueprint for our bodies) and hair. My reference is “Body: Discover What’s Beneath Your Skin,” a Miles Kelly Book, written by John Farndon and Nicki Lampon and published in 2010. This column will consider finger and toe nails, breathing and coughing, saliva, mucus and your food’s long and torturous journey. Most cities and mid sized towns have nail shops where you can have your finger nails and toe nails adorned. Nail painting can be traced back 5,000 years.

  • Here’s a look at what goes on inside you

    In high school, my favorite science course was biology. I can remember Mr. Munley in his wheelchair. Our class went on a field trip to the University of Miami Medical School where we saw the cadavers used by the medical students.

  • Moon-watching easy when you know how

    Long before the first writing (scratches on clay tablets) appeared, our early ancestors noticed that the moon went through a regular cycle of shapes in about 30 days.

  • Here’s how you can tell the stars, planets

    How can one tell one star from another at night? It’s a matter of knowing the sky areas (constellations).

  • Smithsonian guide to stars is a good one

    At a local book store, I yielded to temptation and bought “Stars and Planets,” a Smithsonian Nature Guide written by four authors. Dinwoodie, Gater, Sparrow and Stott. It’s another Dorling Kindersley product with ISBN 978-0-7566-9040-3 and a 2012 copyright. “Stars and Planets” is a trade size paperback that is beautifully illustrated with appealing diagrams. “Stars and Planets” begins with the biggest topic, the Universe. There is a striking visual showing the known universe on the hugest scale, a delicate lacework of superclusters of galaxies with large voids. It resembles a bubble bath!

  • Think a little more and be less frazzled

    Last Sunday’s column dealt with using technology carefully in education. What about technology in everyday life? There is a marvelous book “The Thinking Life,” by P.M. Forni, of The Johns Hopkins University which addresses this issue as well as timeless suggestions for living by Greek and Roman thinkers. “The Thinking Life: How To Thrive in the Age of Distraction” was published by St. Martin’s Press in 2011 with ISBN 978-0-312-62571-9. Dr. Forni also wrote “Choosing Civility” and “The Civility Solution”.

  • Technology helps with learning, but take care

    Since I have been involved in teaching, two different technologies have been applied to learning at the secondary and collegiate level. The first was video (from videocassettes to DVDs) where a student or class might watch a presentation of some historical event, or a set of scientific principles or even a simulated exploration of the human body.

  • Here are numbers that apply in our lives

    One of the best exercises is walking. Cardiologists suggest that each of us walk 10,000 steps per day. Assume each step is 0.5 meters or 19.7 inches. Then 10,000 steps would cover 5,000 meters or 3.11 miles. But studies find that the average American (from age 4 and up) takes only 2,000 steps/day or 1 kilometer.
