    Methods of Evaluation

    • Objective Examinations
      • Example: 1. Standard quizzes, mid-term, and final exams consisting of a variety of tasks and question formats, evaluating all levels of performance according to Bloom's taxonomy (knowledge, understanding, application, analysis, synthesis, and evaluation)(Example question: You are given a pair of binoculars which are labeled "7x50." What do the two numbers represent?)
    • Problem Solving Examinations
      • Example: Midterm and Final Exams also contain problems to solve. (Ex. What is the scale of the star map in mm/deg, given that stars A and B are 15 deg apart)?
    • Projects
      • Example: Each person will build or co-build a working sundial. Students are expected to submit a report and tell the class about how they constructed it.
    • Reports
      • Example: 1. Laboratory exercises to evaluate student comprehension of weekly assignments and assigned reading (Example exercise: Find and determine the azimuth and altitude of Vega, Deneb and Altair (the summer triangle)).
    • Skill Demonstrations
      • Example: 1. Use of the Meade Telescopes during observation nights, to look and examine several celestial objects for every evening.

    Methods of Instruction

    • Laboratory
    • Distance Learning

    Lab:

    1. Critical Thinking: Students are taught what characteristics of a telescope and eyepiece determine magnification, light gathering power, field of view, and resolving power. Using this basic information, students must then answer questions relating different parameters to each other, and what external factors would limit the telescope performance – for example earth based telescopes vs space-base telescopes. (Objectives 11,12,13) Reading: Reading from the required course text is assigned on a regular basis. Weekly lab assignments require students to read procedures and expected analysis (Objectives 9,14,22,27,28). Writing: Term sundial project requires written report. (Objective 26) Field Trips: Students will be required to go on at least one field trip per semester or more (depending on weather and moon phase). (Objectives 1,3,4,10,15,20)

    Distance Learning

    1. Students will watch instructional video on how to complete a laboratory activity. At the end of the laboratory exercise, there are three particularly challenging analysis questions. Students will then interact with each other in a discussion board, where they are given a prompt to discuss one of the three challenging analysis questions in the lab. This discussion board is shaped with hints from the instructor, as to how to solve the problems. Answers to the problems are submitted individually by the students.

    Typical Out of Class Assignments

    Reading Assignments

    1. Reading from assigned text on a weekly basis. Example: Read the Chapter on "Stars for All Seasons". Be prepared to discuss in class. 2. Reading from supplemental handouts. Example: Read the "Meade LX-200 Telescope: Set-up and Take-down Procedure" handout. Students will then list the steps.

    Writing, Problem Solving or Performance

    1. Weekly laboratory reports. Example question: Calculate the magnification for the LX-200 telescope using a 40 mm eyepiece. 2. Written sundial project report. Example demonstration: Calculate, design and build a sundial which functions. 3. Quizzes, Midterm, and final exam to demonstrate acquisition of critical thinking skills and astronomical knowledge. Example exam question: Suppose that you live in Saint Louis, MO. What is the altitude of Polaris?

    Other (Term projects, research papers, portfolios, etc.)

    One assignment is given for each week of class. Each of these assignments will be of a nature that is reflective of the course outcomes. In particular, for assignments that are of a hands-on nature, our online students will acquire this experience through computer simulations, remote access to a robotic telescope, and/or visits to a public telescope observation site (either at a Sierra College Astronomy Department site or one owned by a local astronomy club). Example: Using the LX-200, locate and sketch the crater Copernicus on the Lunar surface.
