New Online Homework System--CANVAS

posted Dec 30, 2017, 2:18 PM by Tom Erekson_lphs   [ updated Dec 30, 2017, 2:28 PM ]

You will have the option to create  a new account, or to log in if you already have an existing account. 
Please use your "@alpinesd.org" gmail account for your Canvas account email.
If you create a new account, you will have to check your email and verify it by clicking the link in the Canvas email they send you.

Click HERE to join the LPHS AP Phyiscs Canvas course. 

After you have enrolledHERE is the link to log in to Canvas.

This is where your online homework will be done from now on. 

There is a Canvas app for your phone if you want to search for it.  After joining this course, you can set up your Canvas app by entering "canvas" as your school site.

Setting up a Canvas Account for Mr. Erekson's classes at LPHS:

  1. Go to the "join" link above.

  2. It will say "You are enrolling in Mr. E's class" and it will request an email address.  You MUST use your Alpine District email address. (That email address is probably something like erekstho000@alpinesd.org.  It is your Skyward login with @alpinesd.org on the end.)

  3. Now there are two options.  You can either make a new account, or login to an existing account.

    1. If you've never used Canvas before, choose "I am a new user."

      1. If you get an “email already in use” error, you apparently have used Canvas before, even though you didn’t know it.

      2. Generally this is because you had a junior high computer class in which the teacher had Canvas accounts created for everyone.

      3. Now you have to try to remember a password that you didn’t even know you had!  Try the default password for district accounts-- your birthdate (MMDDYYYY).  If that doesn’t work, the main login page has a “Forgot Password?” link.

    2. If you HAVE used Canvas, and you used your Alpine District email for your account, choose "I already have a Free for Teachers login."  (You'll need to remember what password you used before.)

    3. If you used Canvas before, but you used a NON-Alpine-District email, choose "I am a new user" and make a new account using your district email address.

  4. Now that you have either logged in or created an account, it will say, "You have successfully enrolled in Mr. Erekson's class."  (If it doesn't, just click on the enroll link again-- for some reason, a few people have had to go to that page twice.)

  5. You're not actually done yet!  To complete your registration you need to log in to your district email account-- Canvas sent an email to it for you to confirm your registration-- open the email and click the link.  

    1. If you have never changed the password on your district email account, it is your birth date, in the format "MMDDYYYY" (two-digit month, two-digit date, four-digit year).

    2. If your district email account is denying you access, it probably means that your parent/guardian still needs to approve the new district AUP for you (this is done via the Skyward-parent-login).

  6. Now that you have an account, it will take 12-24 hours for your account to be sorted into the correct section.

AP Scores in July

posted Apr 12, 2016, 12:25 PM by Tom Erekson_lphs

Fill in AP answer sheets carefully and consistently at exam time or during a pre-administration session. It is especially important to provide name, date of birth, sex, mailing address, and email address.
Sign up for a College Board account on the student AP score website as early as possible. Students must have an account to access their scores.
Some students may already have an account. Have them confirm this by signing in.
Remember the following information, which will be required to see scores in July:
College Board account username and password
2016 AP number (or student ID number if they provided it on their AP answer sheet)
Score Release Schedule
The score release schedule will be available on the student AP score website in May, and students will receive an email in early July reminding them when they can access their scores.
