Instructional Goals and Purposes

Panola College's instructional goals include 1) creating an academic atmosphere in which students may develop their intellects and skills and 2) providing courses so students may receive a certificate/an associate degree or transfer to a senior institution that offers baccalaureate degrees.

General Course Objectives

  • To help students understand the basic need to maintain the Earth's ecosystem
  • To help students understand the basic Earth life support systems
  • To make the students aware of changing global problems as related to environmental science

Specific Course Objectives

  • Discuss the characteristics of living organisms.
  • Identify Earth's life support systems.
  • Explain why biodiversity is important in ecology.
  • Describe the Earth's major biomes.  Explain the major cause of the distribution of biomes on the Earth.
  • Draw and explain an exponential growth curve.  Distinguish between exponential growth and linear growth.  Discuss overpopulation as related to carrying capacity.
  • Distinguish between the following terms:  physically depleted and economically depleted


Grading:  Lecture average (50%) + Lab average (50%) = 100%

For example: Lecture average is 70 and the lab average is 80 then the class average and letter grade would be a 75 & “C”.

Lecture grades will be as follows:

Part 1 Testing at college

Midterm  200 pts.  At the testing center

Final 200 pts.  At the testing center

Part 2 online work

Online Quizzes:

There are 15 quizzes in the course over the topics in lecture. These are mastery quizzes. Which means you must score 90% on the quiz to earn credit for the quiz. For example, if a quiz has 20 questions, then you must score 18 to get full credit. If you don’t score 90% a quiz it will not count for credit. Each quiz is over the major point and terms in the chapter.  You have 5 attempts per quiz. The number of quizzes scored as credit will be divided by 15 for the quiz average.  Average of the online quizzes will be counted twice and is worth up to 200 points.

Online Discussion Topics:

The discussions are over environmental / biological topics. The student must submit an original post for each topic. The original post must be at least 5 sentences. Then the student must reply to 2 other student’s original post. The grade will be based on both post and replies that are made during the week. The instructor will post the topic by Tuesday and the class must complete their post and replies by Saturday at Midnight. The number of completed post will be counted up and divided by the number of topics for an average. This will be counted twice and is worth up to 200 points.

Lecture Total =  800 Points

Lab grades will be as follows:

Journal articles = 100
soil lab = 100
Graphing  = 100

Metric = 100
Water = 100

Weather and environmental data and report = 100

2 test worth 100 points each = 200
Lab Total =   800
