What are Student Hours?
The main purpose of student hours is to offer students an opportunity for one-on-one interactions with the instructor outside of the regular class time. Here’s what typically occurs:
• Scheduled Timing: The instructor will announce the student hours at the beginning of the semester, including the time, day, and location. These details can also be found on the course syllabus. Each Sunday, the student hours for that week will be posted as an announcement on Blackboard, which also gets sent as an email.
• Questions and Clarifications: Students come with questions about lecture material, readings, assignments, or topics that they find confusing. It’s an opportunity to clarify doubts or delve deeper into a subject.
• Assignment Feedback: After grading, students might want to understand mistakes they made on assignments, exams, or papers. During student hours, instructors can provide more detailed feedback and suggestions for improvement.
• Discussing Grades: If students are concerned about their grades, they might meet with the instructor to understand how they’re performing in the class and get recommendations on how to improve.
• Building Relationships: Beyond just academics, student hours can be a time for students to get to know their instructors better, discuss their academic interests, and potentially seek guidance about future courses, research opportunities, or career paths.
• Course Logistics: Students might have questions about upcoming assignments, exam formats, course policies, or other logistical aspects.
• Additional Resources: The instructor can recommend additional resources for students looking to further their understanding, like books, articles, or other supplementary material.
• Personal Concerns: Sometimes, students might discuss personal issues that are affecting their academic performance, such as health concerns, personal crises, or other challenges. The instructor can offer support, understanding, and direct students to appropriate campus resources.

How to turn in your work (homework, practice exam, and exam correction) on Canvas?
For each individual assignment, please take pictures of your work and combine them into a SINGLE pdf, then upload to Canvas. Please make sure the pictures(pdf) are readable orientation and in good order.
Ways to convert your pictures into a SINGLE pdf:
1. Use smartphone app such as pdf scanner, Genius Scan, CamScanner
2. Copy those pictures in word/ google docs, then convert to a SINGLE pdf
3. Use some website like https://imagetopdf.com/ to combine pictures into a SINGLE pdf
Thank you! If you have any questions, please email me. Cheers!
Homework assignments:
Please show all your work and do not copy the solution. Please finish your homework first, then use a red pen to grade your work and make corrections according to the solution. (If you are correct, make a checkmark ✓ next to the problem; if you made a mistake, cross your mistake, then write the correction next to it. Don't just write down the final answer; write down the steps of the correction. ) So leave more space for the problems for corrections.
When you have questions, come to ask me! Cheers! ^o^
I prefer to see homework full of corrections rather than "perfect homework". Sometimes I made mistakes too. Let's learn from our mistakes!
