Description and purpose of the general education course: General Education courses must be introductory and foundational within the offering department or within the General Education Group. They must emphasize breadth, context, and connectedness; and relate course content to students’ future lives: See Preamble: http://umt.edu/facultysenate/archives/minutes/gened/GE_preamble.aspx Scientists and professionals in every natural resource field must reason from empirical data to reach inferences or decisions concerning the systems they study and manage. This course emphasizes the utility of empirical data, the inherent variability of environmental data, and the consequent need for the application of statistical reasoning in the interpretation of data. The purpose of the course is to introduce students to effective means of visualizing, describing, and accounting for variation in order to better understand ecological systems and processes. Using data from a spectrum of environmental applications including forestry, hydrology, and wildlife biology, the course begins with a development of graphical and numerical methods of data analysis. The laboratory component parallels this, and gives students the opportunity to apply these methods to uncover pattern and variability in real data. Students are next introduced to the basic tenets of experimental design and statistical sampling, which, in turn, motivate a treatment of probability models. The last segment of the course integrates probability modeling and data analysis into methods for statistical inference. In laboratory sessions students apply these formal inferential procedures in environmental applications involving techniques such as analysis of variance and simple linear regression. V. Criteria: Briefly explain how this course meets the criteria for the group. See: http://umt.edu/facultysenate/documents/forms/GE_Criteria5-1-08.aspx 1. Rigorously presents a mapping between a real-world system and a human abstraction of the system. The processes and heterogeneity of natural systems are represented in the abstract, as qualitative and quantitative data. Data are consistently referenced to meaningful, measurable ecological attributes, yet the general concepts of data and data analytic methods are reinforced in order to unify the treatment of observations from a range of natural resource applications. Additionally, probability models are used to abstract the data generating processes and are made central to the measurement of evidence in support of alternative statistical hypotheses. 2. Applies analysis, reasoning and creative thinking in the understanding and manipulation of symbolic codes. Data analytic methods are central to the course and are applied extensively in laboratory sessions. Both graphical and numerical modes of analyses are considered. Analyses are not prescribed, however; students must identify the relevant features of the data in light of the problems that are presented to them and then weigh the effectiveness of alternative approaches. 3. Utilizes alternative methods of communication, perception, and expression in order to encourage rigorous thinking. An important component of this course is the empirical evaluation of ecological hypotheses and relationships. This requires, firstly, that the relevant ecological concepts be communicated in statistical terms. Patterns and trends perceived through various analyses of data then must be related back to the natural systems of interest. Thus, the symbolic system is used as a tool to facilitate rigorous analysis, but the results are interpreted and communicated in terms of concrete ecological relationships. VI. Student Learning Goals: Briefly explain how this course will meet the applicable learning goals. See: http://umt.edu/facultysenate/documents/forms/GE_Criteria5-1-08.aspx 1. Demonstrate an understanding of the symbols and the transformations of the system. In laboratory sessions in particular, students will apply formulas and manipulations of data to calculate quantities of interest. Students’ understanding of the need for these transformations will be demonstrated through their selection of an analytical approach and through their interpretation of the data summaries. 2. Relay and interpret information in terms of the given symbolic system. Extraction of information from data is, in essence, the subject of the course. The symbolic system is a means to an end, with the end being a more thorough understanding of the natural systems under study. 3. Apply creative thinking using the symbolic system in order to solve problems and communicate ideas. Throughout the course, students confront real problems in natural resource science and management. They must determine how to efficiently collect data, how to effectively analyze data, and how to draw valid inferences from data in order to solve these problems. VII. Assessment: How are the learning goals above measured? Please list at least one assignment, activity or test question for each goal. 1. Weekly written laboratory assignments utilize real-world data on natural resources. On each of these assignments, students must conceptualize the variables and their values in terms of the symbolic system in order to apply appropriate transformations/formulae. For example, on the 3 rd laboratory assignment, students are supplied with data on black bear dimensions (length, weight). They are then asked to conceptualize the data as continuous quantitative variables (“x” and “y”) and to apply various operations: “Explain in words what is meant by each of the following formulas. Then use the black bear data above to perform the appropriate calculation. 2 1. xi 2. yi 3. xi 4. (xi – x̄ˉ )2 5. xi yi ” 2. Symbolic representation of attributes or relationships is a major theme of the course. For example, in the 5th laboratory assignment, students are supplied with tree biomass and tree size data and then are asked to i) describe how certain attributes are statistically related (using linear regression) and ii) explain what the regression coefficients actually mean in terms of tree biology: “Fit a linear regression of tree biomass on tree basal area and report the values of the slope and intercept coefficients. Interpret the slope coefficient: What does its value actually mean?” Carrying out this exercise requires an ability to translate the tree measurements into a symbolic representation, apply the appropriate mathematical formulae to that symbolic representation, then translate the symbolic results of those operations back into the real-world domain of tree size inter-relationships. 3. Examination questions are designed to challenge students beyond applications of formulae or interpretations of data. In particular, these questions are designed to assess whether students have an understanding of the foundations and limitations of the statistical methods. For example: “A crew contracted to replant a clearcut claims to have planted 4,500 seedlings per acre. You decide to check this claim by installing plots at 36 random locations across the cutblock. Across your plots, you observe a mean of 4,052 seedlings per acre with a standard deviation of 2,247 seedlings per acre. (a) At the 5% significance level, is there evidence that the planting crew overstated the stocking level? (b) Explain the need for the significance test in part (b) above. That is, since the sample mean is 4,052 seedlings per acre, doesn’t that by itself contradict the planting crew’s claim? ” To properly answer these questions, students must be able to conceptualize the sample data as a single realization of a population of different possible outcomes. Part (a) requires them to logically develop a statistical hypothesis testing framework and carry it through to a logical conclusion. Doing so relies heavily on translation of the problem into the symbolic system of random variables, as well as on back-transformation of the results into a very practical conclusion regarding operational/contractual compliance. Part (b) pushes them to communicate why these symbolic systems are used, and how they are relevant to this type of real-world problem. VIII. Justification: Normally, general education courses will not carry pre-requisites, will carry at least 3 credits, and will be numbered at the 100-200 level. If the course has more than one pre-requisite, carries fewer than three credits, or is upper division (numbered above the 200 level), provide rationale for exception(s). Not applicable. IX. Syllabus: Paste syllabus below or attach and send digital copy with form. The syllabus should clearly describe how the above criteria are satisfied. For assistance on syllabus preparation see: http://teaching.berkeley.edu/bgd/syllabus.html See attached. Please note: Approved general education changes will take effect next fall. General education instructors will be expected to provide sample assessment items and corresponding responses to the Assessment Advisory Committee.
