Course Textbook

Anita Wasilewska
LOGICS FOR COMPUTER SCIENCE:  Classical and Non-Classical
Springer 2019

ISBN 978-3-319-92590-5             ISBN 978-3-319-92591-2 (e-book)

You can get the book in Hard cover, or in Electronic form. Springer has an option of providing you with chapters of your choice

Here is  a copy of the MY BOOK for you to use. Please read the  relevant chapters before and after the LECTURES.
Study  Examples and Problems solutions - you need to  know them  all for your TESTS.

COURSE TEXTBOOK COPY

The course outcomes and catalog description are in the official course description page.

Course Goal

The goal of the course is to make student understand the need of, and to learn the formality of logic. The book, and the course is developed to teach not only intuitive understanding of Classical and Non-Classical LOGIC but (and mainly) to teach formal, symbolic  logic as scientific subject, with its language, definitions and main theorems and problems.

Course Structure

I will progress relatively slowly, making sure that the pace is appropriate for the students in class. The book is written with students on my mind so that they can read and learn by themselves, even before coming to class. For sure, it is also essential to study and review material  after the class. There is no recitations, but I will cover  in class solutions of  some previous  tests and quizzes and will held questions/answers sessions in class.  Students are also responsible to study and know solutions to all chapters examples  and problems  that are not included in Lectures. I may include them in Tests.

Grading General Principles and Workload

TESTING

ALL TESTS, including the FINAL Examination will be given IN CLASS

The PRELIMINARY schedule is poste
d below. Changes will be posted on the course Webpage
 and  on BRIGHT SPACE

We do not give  MAKE-UP TESTS  except of documented cases of illness or documented emergencies


WORKLOAD
there will be 2 QUIZZES,(40pts Total) MIDTERM (80pts), and  FINAL (80pts).
 I will also give some  Extra Credit Quizzes for  (20 extra points total).
The consistency of your efforts and work is the most important for this course.

None of the grades will be curved

Final Grade Computation

You can earn up to 200 points + x extra points = 200+x points during the semester.
The grade will be determined in the following way: number of earned points divided by 2 = % grade.
The % grade is translated into a letter grade in a standard way - see SYLLABUS for explanation

TESTS FINAL Schedule

EQ1 - Thuesday, September 15 - extra credit EQ1
Q1  - 
October 6 - regular Q1
Fall Break - October 12 -13
MIDTERM Tuesday, October 20
EQ2
Tuesday, November 3   extra credit EQ2
Q2
Tuesday, November 17 - regular Q2

ACADEMIC INTEGRITY STATEMENT

Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Any suspected instance of academic dishonesty will be reported to the Academic Judiciary. For more comprehensive information on academic integrity, including categories of academic dishonesty, please refer to the academic judiciary website at A Judiciary Website

For procedures and information go to the following website: http://www.sunysb.edu/ehs/fire/disabilities.shtml

Critical Incident Management

Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of University Community Standards any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn. Faculty in the HSC Schools and the School of Medicine are required to follow their school-specific procedures. Further information about most academic matters can be found in the Undergraduate Bulletin, the Undergraduate Class Schedule, and the Faculty-Employee Handbook.
