Homework System

Students are required to purchase a key to Mastering Astronomy. The key comes bundled with the text if purchased at the Blinn bookstore. Otherwise, you can obtain a key from the Mastering Astronomy website: www.masteringastronomy.com. The course ID for this section is PHYS1403302SP14.

Planetarium Software

We will use SkyGazer planetarium software for several of the labs. The software resides on the laboratory computers, but also comes bundled with the text if purchased at the Blinn bookstore. You may load this software on your personal computer for use away from the laboratory.

Course Requirements


Exams

There are three exams during the semester and a comprehensive final. I will give a make-up exam ONLY IF you have a valid excused absence recognized by the college.

Exams generally comprise multiple-choice questions and short-answer questions. The exams are given in two stages: First, the entire exam is given closed-book. Following the closed-book exam students retake the multiple-choice portion open book. This exam is called a pyramid exam. The overall exam grade is a combination of the closed-book and pyramid portions.

Astronomy Projects and Practicum

During the semester, students will be assigned two projects to be completed outside of the regular classroom hours. In addition, students will receive instruction in the use of star charts and how to recognize and identiry various constellation, stars and other objects in the sky.

Labs

The lab schedule is provided in the detailed schedule on eCampus: Lessons->Phys 1403 Handouts->Detailed Class Schedule. Laboratory time will be used primarily for collecting data. Students should expect to complete questions and calculations outside of lab. Labs are generally due the by the end of the next laboratory period. You must be present the day the lab is assigned in order to get credit for it, with the following exception: Labs utilizing the SkyGazer software may be completed at home on your own in advance of the relavent lab day, and submitted on the day the lab is assigned.

Homework

There is an online home work assignment for each chapter. Homework utilizes the Mastering Astronomy homework system. Homework assignments are due at 11:59 PM on the evening before the exam covering the relavent chapters.

Optional Service Learning Project

Students may opt to complete a Service Learning project involving community outreach. Details are available on eCampus: Lessons->Phys 1403 Handouts->Service Learning Project.

Evaluation


Criteria

TypeWeightTopicNotes
Exams 1-3

The overall grade for each of the three major exams is calculated according to the following:

Exam Grade = 0.9 (closed-book score) + 0.1 ( pyramid exam score).

Projects and Practicum

Grades from the two projects and the two practicum quizzes will be weighted equally to deteremine the overall grade for this category.

Overall Exam Grade 40% WITH Service Learning

NOTEYou must score at least a 60% overall on your homework grade to be eligible for this option.

The overall exam grade is a combination of the major exam grades and the four project and practicum grades.

I drop the lowest of the three major exam grades and average the remaining two major exam grades with the average of the four project and practicum grades.

 

Overall Exam Grade 55% NO Service Learning

The overall exam grade is a combination of the major exam grades and the four project and practicum grades.

I drop the lowest of the three major exam grades and average the remaining two major exam grades with the average of the four project and practicum grades.

Service Learning 15%

If you are eligible for, and successfully complete a Service Learning Project according to the requirements in the document referenced above, you will receive a grade of 90%.

Homework 12.5%

Homework is graded automatically by the Mastering Astronomy system.

  • Each assignment will has a due date. You will receive a 10% grade deduction for every day the homework is late. Due dates will typically be midnight on the day before I give an exam covering the material.
  • You have a maximum of 6 attempts to answer any problem.
  • For multiple-choice questions don’t just guess at the answer until you find the correct one. If you guess wrong, you will be penalized according to the number of possible answers. For example, if there are four possible answers and you guess wrong once, the maximum possible score on that problem will drop to 75%.
  • You can ask for a hint. If you ask for a hint, you will be penalized 1% for each hint you receive.
  • If you answer a question incorrectly, you receive a deduction of 3% per incorrect answer.
Labs 12.5%

Labs are grades according to the policy set forth in the document on eCampus: Lessons->Phys 1403 Handouts->Phys 1403 Lab Policies and Procedures.

Blinn College Policies


Blinn College policies on civility, class attendance; scholastic integrity; students with disabilities; final grade appeals; and electronic devices as stated in the Blinn College Student Handbook, Faculty Handbook, Blinn College Catalog and specific technical program handbooks. All policies, guidelines and procedures in the Student and Faculty Handbook and the Board and Administrative Policy Manuals are applicable to this course

Civility Statement

Members of the Blinn College community, which includes faculty, staff and students, are expected to act honestly and responsibly in all aspects of campus life. Blinn College holds all members accountable for their actions and words. Therefore, all members should commit themselves to behave in a manner that recognizes personal respect and demonstrates concern for the personal dignity, rights, and freedoms of every member of the College community, including respect for College property and the physical and intellectual property of others.

      Civility Notification Statement. If a student is asked to leave the classroom because of uncivil behavior, the student may not return to that class until he or she arranges a conference with the instructor; it is the student’s responsibility to arrange for this conference. 

      This statement reflects step one in a possible four step process.  The Incivility Protocol is detailed in the Blinn College Student Handbook.

Attendance Policy

The College District believes that class attendance is essential for student success; therefore, students are required to promptly and regularly attend all their classes. A record of attendance will be maintained from the first day of classes and/or the first day the student’s name appears on the roster through final examinations. If a student has one week’s worth of unexcused absences during the semester, he or she will be sent an e-mail by the College District requiring the student to contact his or her instructor and schedule a conference immediately to discuss his/her attendance issues. Should the student accumulate two weeks’ worth of unexcused absences, he or she will be administratively withdrawn from class.

There are four forms of excused absences recognized by the institution:

  1. observance of religious holy days—The student should notify his or her instructor(s) not later than the 15th day of the semester concerning the specific date(s) that the student will be absent for any religious holy day(s);
  2. representing the College District at an official institutional function;
  3. high school dual credit students representing the independent school district at an official institutional function; and
  4. military service.

Other absences may be considered excused at the discretion of the faculty member with appropriate documentation.  A student enrolled in a developmental course is subject to College District-mandated attendance policies. Failure to attend developmental classes shall result in removal from the course as defined by the College District.

It is the student’s responsibility to officially drop a class he or she is no longer attending.  To officially drop a class the student must obtain the class withdrawal form from Enrollment Services, complete the class withdrawal form, secure the required signatures, and return the completed form to Enrollment Services. The last day to drop with a Q is according to the Academic Calendar.

Scholastic Integrity

Blinn College does not tolerate cheating, plagiarism, or any other act of dishonesty with regard to the course in which you are enrolled.  The following text defines the faculty member’s responsibility with regard to the scholastic integrity expectation for this and all courses at Blinn College.

It is the responsibility of faculty members to maintain scholastic integrity at the College District by refusing to tolerate any form of scholastic dishonesty.  Adequate control of test materials, strict supervision during testing, and other preventive measures should be utilized, as necessary, to prevent cheating or plagiarism.  If there is compelling evidence that a student is involved in cheating or plagiarism, the instructor should assume responsibility and address the infraction.  Likewise, any student accused of scholastic dishonesty is entitled to due process as outlined in Blinn College Board Policy FLB (Local).  The Scholastic Integrity Policy is located in the Blinn College Student Handbook. In a case of scholastic dishonesty, it is critical that written documentation be maintained at each level throughout the process.

Blinn College is dedicated to providing the least restrictive learning environment for all students. Support services for students with documented disabilities are provided on an individual basis, upon request. Requests for services should be made directly to the Office of Special Populations serving the campus of your choice.  For the Bryan campus, the Office of Special Populations (Administration Building) can be reached at (979)209-7251.  The Brenham, Sealy and Schulenburg campuses are served by the Office of Special Populations on the Brenham campus (Administration Building Room 104) and can be reached at (979)830-4157.  Additional information can be found at www.blinn.edu/disability/index.html.

Final Grade Appeal

If a student wishes to appeal a final grade in a course, Blinn College Board Policy FLDB (Local), Course Grade Complaints, outlines the timeline for the appeal and the four steps in the appeal.  This policy is located in the Blinn College Student Handbook.

Electronic Devices

Cellular telephones and beepers/pagers must be disengaged while the student is in the Blinn College Library or any classroom/lab, unless otherwise instructed. Any noncompliance with this policy shall be addressed in accordance with the College District civility policy (administrative policy).  This information is contained in Blinn College Board Policy FLB (Local).
