General Information

Description: 3 hours, 3 credits: This course presents an overview of computer science (CS) with an emphasis on problem-solving and computational thinking through 'coding': computer programming for beginners. Other topics include: organization of hardware, software, and how information is structured on contemporary computing devices. This course is pre-requisite to several introductory core courses in the CS Major. The course is also required for the CS minor. MATH 12500 or higher is strongly recommended as a co-req for intended Majors.

Grading Policy

Expectations: Completing homework is an essential part of the learning experience. Students are expected to learn both the material covered in class and the material in the online Labs, the textbook and other assigned reading.

Honor Code: You are encouraged to work together on the overall design of the programs and homework. However, for specific programs and homework assignments, all work must be your own. You are responsible for knowing and following Hunter College's Academic Integrity Policy:

Hunter College regards acts of academic dishonesty (e.g., plagiarism, cheating on examinations, obtaining unfair advantage, and falsification of records and official documents) as serious offenses against the values of intellectual honesty. The College is committed to enforcing the CUNY Policy on Academic Integrity and will pursue cases of academic dishonesty according to the Hunter College Academic Integrity Procedures.

All incidents of cheating will be reported to the Office of Student Conduct in the Vice President for Student Affairs and Dean of Students office.

Course Format: This course is taught as a blend of synchronous online meetings and online as well as in-person activities. Each week the course meets:

• 1.5 hours of lecture (Tuesdays, 9:45am-11:00am, Zoom -- link provided on Blackboard),
• 0.5 hours of in-person assessments (appointments and drop-ins between Mondays-Fridays, 11am-5pm, 1001E Hunter North), and
• 1.0 hours of Online Labs to be completed by the students independently (links to the labs can be found in the Course Outline).

Lecture Preview: Before every lecture, there is a short on-line quiz based on the material for the week. The preview is available on Blackboard the day before lecture and can be repeated as many times as you would like until the start of lecture. Turning in lecture previews will only help your grade. There are no make-ups for lecture previews. Instead, if you miss a lecture preview, your grade on the final exam will replace that grade.

Lecture Participation: At every lecture (Tuesdays, 9:45am-11:00am on Zoom), we will administer a lecture quiz available electronically via Gradescope. Completed lecture quizzes are given full credit. The quiz will only be available for 5 minutes when we announce it during lecture. Turning in lecture quiz will only help your grade. There are no make-ups for lecture quizzes. Instead, if you miss a lecture quiz, your grade on the final exam will replace that grade.

Quizzes: Every week, there will be an quiz to be taken in 1001E HN, on the lecture notes, reading, submitted programs, and programming assignments.

• As the semester progresses, quizzes will include review questions as well as short programming exercises based on the homework.
• All quizzes must be taken by the deadline.
• Quizzes are on paper (echoing the style of the final exam and the first pass of many programming job interviews).
• For the quizzes, you may not use any notes, books, or any computer device (laptop, phone, calculator, smart watch, etc.).
• Quizzes are offered 11am-5pm Mondays to Fridays, when classes are in session in 1001E HN. You may sign up for a time slot in advance or drop in. Advance sign-up for quizzes will be available a week before classes start (see class Blackboard page for links).
• There are no make-up quizzes. Instead, your score on the final exam will replace missing quiz grades (the final exam will also replace a quiz grade when you take the quiz but do better on the final exam).

Code Reviews: Every two weeks, there will be an in-person code review on the recently submitted programs.

• For each code review, you choose one of the programs due the previous week to explain on the whiteboard.
• All code reviews must be taken by the deadline.
• There are no make-up code reviews. Instead, your score on the final exam will replace missing code reviews (the final exam will also replace a code review grade when you take the code review but do better on the final exam).
• Code reviews are on the whiteboard (echoing the style of many programming job interviews).

Weekly Online Lab (replaces a recitation section): Each week, you are expected to work through the associated Online Lab. These are available on the course webpage (you will need a computer with Python and Unix shell, and as the term goes on, C++. See the first lab for installation instructions). Laptops will also be available in 1001E HN with all required software.

Homework: Programming exercises are posted on the class website, usually three weeks before the due date. They reinforce concepts covered in lecture and lab. Note that as the semester progresses, the programs will require work on design and programming outside of class to complete. You should plan to spend approxiimately 3 hours per week on programming exercises. To receive full credit for a program, the program must perform correctly, must include comments, be written in good style, and be submitted by 6pm on the due date.
While every 5 programs should be worked on the week of the corresponding lab, due dates are staggered to provide flexibility (should you be unable to work for a few days you need not miss the deadline). Students who work on the programming assignments the week of the corresponding lab tend to have greater success rate in the course. Students who work on assignments at the due dates are more likely to miss deadlines and fall behind.
Programs are submitted via gradescope. You can miss up to 5 programming assignments without affecting your grade (if you turn in all the programming assignments, we will drop the lowest 5 scores). No late homework is accepted.

Final Exam: The final exam is required. It is comprehensive, covering all the material of the course. Sample and past exams are available on the course webpage.
We will end most lectures with past exam questions and review to prepare for the final. You must take and pass the final (60 points or more) to pass the course.

Grades: The grading for the course will be based on:

• Programming Assignments: 30%.
• Lab Quizzes: up to 25% (if you miss a quiz, or do better on the final exam, your grade on the final will replace that paper quiz grade).
• Code Reviews: up to 5% (if you miss a code review, or do better on the final exam, your grade on the final will replace that code review grade).
• Lecture Previews: up to 5% (if you miss a lecture preview, or do better on the final exam, your grade on the final will replace that lecture preview grade).
• Participation (Lecture Quizzes): up to 5% (your grade on the final will replace the grades for missing lecture quizzes).
• Final Exam: 30% (up to 70% if you do better on the final exam than on lab quizzes, lecture previews, and lecture quizzes).
