Southeastern Louisiana University Dual Enrollment Program--Chemistry

Transcription

1 Southeastern Louisiana University Dual Enrollment Program--Chemistry The Southeastern Dual Enrollment Chemistry Program is a program whereby high school students are given the opportunity to take college chemistry courses at their high schools and receive credit on their high school and university transcripts. Southeastern is offering a progressive pair of courses in chemistry during the academic year. Each course consists of about 130 hours of instruction and practice; schools in which students only meet with the teacher an hour or less per day will not be successful completing a dual enrollment course in just two quarters. The courses are: CHEM 101 General Chemistry I (for non-science majors). Credit 3 hours. The first of a two semester sequence covering the following general topics: metric and temperature conversions, density, calorimetry, mixtures/compounds/elements, chemical and physical properties, structure of the atom and electron configuration, periodic table, bonding, chemical formulas and nomenclature, moles, stoichiometry, chemical reactions, gas laws, and properties of gases, liquids and solids CHEM 102 General Chemistry II (for non-science majors). Credit 3 hours. Prerequisite: Chemistry 101. A continuation of Chemistry 101 covering topics such as: solutions, concentrations (% composition and molarity), acids/bases, ph, buffers, kinetics, equilibrium, solubility, oxidation/reduction, nuclear chemistry, and an introduction into organic chemistry and biochemistry. Program Requirements From the High School: A computer lab must be available to all Dual Enrollment chemistry classes two times per week (or once per week if another day per week is devoted to solving homework problems on paper) for the practice portion of the course. This can be a hard-wired classroom or a wireless cart. From the Teacher: Any teacher new to the program must complete the corresponding workshop during the summer at Southeastern s main campus in Hammond. Any teacher already in our program who would like to teach new classes must complete the workshop for those new classes during the summer at Southeastern s main campus. All teachers (new and returning) must attend one half-day workshop at the end of the summer to copy all online course materials and receive any revisions to the Program Guidelines. The teacher(s) must agree to follow the rules of the program as given by Southeastern and outlined in the Dual Enrollment Eligibility Framework and Memorandum of Understanding. It is highly recommended that the teacher be certified in the area for the course they wish to teach. From the Students: Students must be in the 10 th, 11 th or 12 th grade. Students must be on track to complete the Core 4 curriculum with no developmental coursework required. Students must have a PLAN, ASPIRE or ACT equivalent composite score of 18 or greater Students must have a PLAN, ASPIRE or ACT equivalent Mathematics sub-score of 19 or greater Students must be enrolled in a high school chemistry course while dual enrolled To enroll in CHEM 102, the student must have successfully completed CHEM 101 with a D or better. Program Costs To the School or Student: One access code must be purchased by the high school on behalf of each student per course. Each code costs $25 (if billed in bulk to the school) and gives the student access to the software used in the courses. Schools may handle this fee in different ways. Some schools fund it and some pass the fee on to the parents as a course fee. Southeastern rental textbooks are provided to the dual enrolled students at no cost. If there are other students in the high school course who are not dual enrolled, they will not be able to borrow a textbook (they will only have the high school textbook). Any lost text shall be reimbursed to Southeastern by the high school. The school, in turn, can request the fee from the student who lost the book. Reduced tuition will be charged for each dual enrollment course enrolled in with year-long courses being billed in the spring. Please see the Eligibility Framework document for complete details. To the Teacher: There is no cost to the teachers.

2 Program Benefits To the School: Academic Endorsement is received for each eligible student who enrolls in the Dual Enrollment Program. Certificates of completion are provided for all students who enroll in and successfully complete Dual Enrollment Courses. Note that high schools may choose to place ineligible students in the same class with eligible students to fill the classroom. Our experience over the past few years shows that ineligible students often benefit from being in these classes. For example, such students have experienced an increase of 2 7 points in their ACT Math subscores. To the Teacher: Ongoing support is provided, via telephone, and site visits, throughout the duration of any Dual Enrollment course from the Southeastern Dual Enrollment Chemistry Coordinators. All necessary assessment materials are provided, including all assignments, quizzes, practice tests, tests, and final exams. A free account with the online is also provided. All grading and grade book calculations for the university course requirements are done by Southeastern Professional Development credit is given for any summer training sessions attended To the Student: Regular periodic feedback and evaluations of student work by Southeastern faculty throughout the semester/academic year Any student eligible for the Dual Enrollment Program who enrolls in the Program and completes the course with a passing grade will receive college credit for that course 2015 Summer Workshops for Dual Enrollment Chemistry Session Title Dates Audience General Chemistry I (Chem 101) General Chemistry II (Chem 102) ½ Day Workshop May 26 & 27, am 3pm May 28, am 3pm July 21, am 12pm Mandatory for all new CHEM101 Dual Enrollment Chemistry teachers Mandatory for all new CHEM102 Dual Enrollment Chemistry teachers Mandatory for all Dual Enrollment Chemistry teachers Note: Once a teacher has completed the workshop for a particular course, he or she does not have to repeat that workshop in subsequent summers. The only mandatory workshop for returning teachers who do not wish to teach any new courses is a ½ Day Workshop at the end of the summer. This ½ Day Workshop must be repeated every summer.
