Palo Alto High School journalism students are empowered to lead their publications and their learning



(Cross-posted on the Google Student Blog.)

Editors note: One of the main discussion points of Education on Air, the free online conference from Google on May 8th-9th, was how we can empower students in their learning. Our guest author today, Coby Parker, is one of the students who shared views as part of the student empowerment panel at the conference. Coby and his classmate and co-author Claire Liu are the Editors-in-Chief of the Campanile, the student-created, award-winning publication at Palo Alto High School. Today they share more insights about how the journalism program at his school, led by educator Esther Wojcicki, motivates students. We hope this provides ideas for teachers as they head into summer and next year.

One of the most vital pieces of an education is student empowerment. Here at Palo Alto High School, students are given the opportunity to take complete control over their academic and creative journey through the journalism program Esther Wojcicki (or “Woj”) has created.

The journalism program and publications that Woj has built over the last 30 years are incredibly appealing to our student body, as demonstrated by the hundreds of kids who choose to enroll in “Beginning Journalism” each year. High school is a challenging time – young people are faced with the obstacles presented by academic stress, extracurricular commitments and changing social norms. For me, it was difficult to find something to spend my time doing that provided both intellectual stimulation and creative escape.

Joining Paul Kandell’s “Beginning Journalism” class sophomore year, and then enrolling in The Campanile, a school newspaper that Woj advises, has granted me the space to grow my academic independence and leadership ability. Our entire publication is headed by students only. Student editors like me lead story ideas, and staff writers pick and choose the pieces they feel passionate about writing. There are no limitations on story ideas – as long as a proposal is relevant, we give it the green light.


If you like what you see in this highlight reel for the Education on Air student empowerment panel, check out the full session.

After students submit first drafts, peers make edits on Google Drive, suggesting changes, marking grammar and AP style errors, and more. When “production” begins, the entire staff stays on campus in the Media Arts Center until 9 P.M. each night to design the tangible, paper product. The entire process is run by students, meaning it is the high schoolers alone who create the complex and sophisticated end product. We even sell advertisements to pay the bills. If a student needs help, he or she asks a high school peer – not Woj. Woj leads very much from behind – an approach that may be challenging for many educators, but one that is truly beneficial to the strengthening of student initiative.

Essentially, the only time Woj intervenes is if she has a specific design suggestion, brief lesson, or if a specific story may contain libel or is unethical in some way – this happens pretty infrequently. In my three years on The Campanile, Woj has never forced us to do or publish anything we did not want to. Her approach provides students the room to take on big projects and develop a self-confidence and desire to test boundaries, both personal and societal.

My colleague Claire Liu, another Editor-in-Chief, explained the impact the course has had for her. “As a staff writer, I have pursued a range of stories, standard and provocative. Whether I was documenting a sports game, addressing race relations or discussing gender roles and sexuality through the paper, I have felt Woj’s subtle but ever present support. In this rare, fast-paced and invigorating environment, we are allowed to fail, and encouraged to take risks and challenge the norm, all while being supported by a teacher who consistently has our back (even when she’s feeling a bit hesitant, and even if we mess up big time!). Students join The Campanile expecting to learn how to design a newspaper page and write articles. They gain not only those things, but an entire toolbox of powerful character traits and skills that will last them a lifetime.”

In psychology class I recently learned the difference between intrinsic and extrinsic motivation. Generally in the education system, students work hard to get good grades and please their teachers – extrinsic motivation. In The Campanile, the motivation is more intrinsic. The threshold to get an A is the bare minimum, and anything above and beyond that has to come from the individual student’s efforts. The reward is much more basic than an A on the report card; it’s being able to hold a newspaper and point to the real impact that he or she made.

Our advisor, Woj, truly plays the role of advisor and not teacher. She’s there for us when we need her, but when we don’t, she doesn’t impose on us or make us do anything we don’t want to. In the end, we are responsible for our actions, the dime stops with us. I hope more schools can implement programs like The Campanile and empower students to take charge of their own education.

Young people who are changing the world through science



(Cross-posted on the Google for Education Blog.)

Sometimes the biggest discoveries are made by the youngest scientists. They’re curious and not afraid to ask, and it’s this spirit of exploration that leads them to try, and then try again. Thousands of these inquisitive young minds from around the world submitted projects for this year’s Google Science Fair, and today we’re thrilled to announce the 20 Global Finalists whose bright ideas could change the world.

From purifying water with corn cobs to transporting Ebola antibodies through silk; extracting water from air or quickly transporting vaccines to areas in need, these students have all tried inventive, unconventional things to help solve challenges they see around them. And did we mention that they’re all 18 or younger?

We’ll be highlighting each of the impressive 20 finalist projects over the next 20 days in the Spotlight on a Young Scientist series on the Google for Education blog to share more about these inspirational young people and what inspires them.
Then on September 21st, these students will join us in Mountain View to present their projects to a panel of notable international scientists and scholars, eligible for a $50,000 scholarship and other incredible prizes from our partners at LEGO Education, National Geographic, Scientific American and Virgin Galactic.

Congratulations to our finalists and everyone who submitted projects for this year’s Science Fair. Thank you for being curious and brave enough to try to change the world through science.

Present to anyone from wherever you are



Google Slides helps you share your big ideas with the world, but sometimes presenting these ideas can be challenging. In June, Slides added support for Chromecast and Airplay, which made it easier to project your slides on the big screen. Now there’s another new way to share your work: easy presenting to Hangouts video calls. Teammates, partners, clients and classmates can see your ideas, even if they’re on the other side of the planet.


As you get ready for the big meeting, all you need is your Android phone or tablet. With one tap of the present button, you’ll see the option to present to a Hangouts video call. Meetings that are scheduled on your calendar will automatically be listed, so you can be up and running in no time.

You’ll also get a handy look at whos on the call before you start presenting. Once you’re ready to rock, you can use your mobile device to advance slides, view speaker notes and stay on track with a built-in timer.

Presenting just got even easier with Google Slides on Android – available starting today and rolling out over the next few days.

Q What are the reason of TCH Drop due to bad quality Uplink

Ans:

 Probable reasons for poor Uplink Quality
1. Poor Frequency plan (TCH)
2. Interference in UL
3. Overshoot of neighboring cells.
4. Poor Level on the UL.
5. Fault in TCH TRX
6. Codec issues.
7. Transmission related issues.
8. Boosters/Repeater related issues.
9. External interferences – Restricted area/Electronics equipment Factory/Jammers.


Uplink Quality Checkpoints
1. Poor Frequency Plan
a. Always resolve DL quality issues before attempting to correct the UL.
2. Interference in UL
a. Avoid using Co & adjacent TCH frequencies in the same cell or site.
b. Avoid using co TCH on neighboring cells.
c. Wrong values of the HSN or MAIO/MAIO Offset.
i. Do not reuse HSN in nearby sites.
ii. Review MAIO & MAIO Offsets as per the TCH plan(1x1, 1x3, adhoc etc).
d. In cases where intra-cell handovers are allowed, interference will cause a lot of intra-cell handovers thus degrading the UL & DL quality
3. Overshooting of neighboring cells.
a. TCH reuse becomes tight is there’s a lot of overshooting of nearby cells. Allow only 1 or up to 3 dominant servers only.
b. Reduce the overshooting of neighboring cells.
4. Poor level on the uplink
a. Possible coverage problem.
b. Rx Level Versus Rx Quality distribution per TRX on a cell.
c. TMA’s can be used judiciously used to enhance UL level.
5. Fault in TCH TRX
a. Check the alarm printouts.
b. (BTS UL Quality history at 24 Hour/10 day resolution). Check if the BTS is within defined interference boundary limits & for how long it has been out of limits of acceptable interference.
c. BTS Analyzer. Check if the BTS is within defined interference boundary limits.
d. Path balance for TCH TRXs

6. Codec Issues
a. AMR related quality issues.
b. AMR related parameter settings. Check if the Codec (AMR/Non-AMR) settings are OK.
c. Check if the BTS s/w version is OK & supports the codec.
d. If the problem is with many sites in a BSC then that BSC’s parameter file needs to be checked/updated.
7. Transmission related issues.
a. Check the BSC ET availability & Quality profile .
b. Check the TCSM ET availability and quality,.
c. Check the QOS
8. Boosters/Repeater related issues.
a. Check for repeaters and/or booster installations. Check for spillage of the repeater signals in areas not intended to be covered.
b. If repeaters are a problem( you will know once you switch off the repeater for a short duration), adjust the gain of repeater
c. Adjust the repeater antenna & orient it to closest serving cell. DO NOT latch a repeater with a DISTANT dominant cell.
9. External Interferences
a. If you suspect external interference on single TRX, lock the TRX & see if the problem persists. If the problem is resolved then the TRX or its implementation is at fault.
b. If you suspect external interference on the entire site, Lock the site & scan the area served by the site for potential interferers. Somebody may be transmitting the same frequencies in the serving area of affected site.
c. Workaround: If you indeed found an interferer over which you have no control, try allocating a different frequency (beyond 2 MHz). There’s a high probability that the frequency which is being severely interfered now will no longer be interfered after frequency change.

How Bitwise Operators are Used an Example Program

Well, one-by-one we’ve discussed each of the Bitwise
Operator
. Starting from Operation
on Bits and Bitwise Operators
, we moved on to Right/Left
Bit Shift Operators
then discussed Decimal
Number to Binary Conversion Program
. and at last Ones
Complement and XOR Operators
. After having so much theoretical it’s
time now for a nice Example Program, which is the topic of today’s post.
The code here is basically to show how these bitwise operator are used rather
than what they are used for.
