San Francisco Uses Weighed Student Formulas to Track School Needs

What Weighted Student Formulas Do

One of the primary features of the WSF is that it allows San Francisco Schools more flexibility than the previous system, called the "staffing ratios" model. Through staffing ratios, the central office basically directed school sites to spend the bulk of their resources in a particular way, through allocations of staff and a small supplies budget. This system gave schools little control over their financial resources. Under the WSF, each school site receives a budget denominated in dollars instead of positions and decides what staff and non-staff items to purchase with those dollars. Under this approach, each school has more room to design and use innovative instructional programs that match the specific characteristics and needs of its students, parents, and community. Central administration helps and monitors schools in a number of important ways, but it shares more decisions with principals and local school governance teams called School Site Councils--the people who are most familiar with what their schools need.

Resources are also distributed based on the specific needs of each SFUSD student. We all know that different students have different educational needs, which often mean educational services with different price tags. A student with special education needs or a student who does not speak English requires more than a native speaker of English with no special education needs. Some schools enroll students from family backgrounds with lower incomes who on average start school at a disadvantage compared to students from middle class or affluent families. The new formula reflects these needs by channeling funds to specific student characteristics such as grade level, special education needs, needs of English Language Learners (ELL's), and socioeconomic status.

Finally, the WSF distributes basic education resources more consistently on a per-pupil basis across schools, and all stakeholders are better able to see and understand how resources are allocated and spent in each school. Did you know how much each student at each school received under the old budget system? Did you know whether or not one school received a higher share of public resources than others? The WSF makes the largest part of the District's budget more transparent. The public can now see exactly why each school gets the resources it does and that the school is being treated like every other school in the District following a common set of principles.

What Do Schools Do

Schools' added responsibilities primarily involve developing their budgets and school academic plans. Each school's principal and School Site Council discuss their school's needs, challenges, and priorities and build its budget accordingly for the upcoming school year. They determine the number of each type of staff they need as well as their non-staff requirements. During the year, schools can revisit their original decisions by requesting budget transfers. This requires ongoing evaluation of how the original plan is working out. In short, giving schools more flexibility means more responsibility. But these are responsibilities that will build dialogue and awareness among more members of each school community - especially responsibilities to think creatively and in many cases to make different choices than the central administration may have made for them previously.

To make this initiative work, principals and site teams have needed training and technical assistance. School Site Council members have of course needed information on a number of questions -- about developing an academic achievement plan, financial management, how to include local teams in decision-making, or simply how to use the software to build their budgets. The District sees building the capacity of principals and School Site Councils as crucial to the successful implementation of a WSF and has offered training and vehicles for technical assistance through each step of the WSF process. Additional training and outreach to School Site Councils will continue to be provided and refined in the future.

Inexpensive Salsa Dance Classes in San Francisco

Dance SF is the top salsa dance school that caters to the needs of aspiring salsa dancers.

Our classes are only $50 for a 4-week dance program taught by experienced salsa dance instructors. IF you are looking for a location near you in the San Francisco Bay Area, check out http://www.dancesf.com/home.htm.

Whether you are young or old we have salsa dance classes for everyone! But you shouldn't only use those moves in the dance studio. Why not go out to a local salsa dance club and show off those new moves! It's a great way to improve upon your newly acquired skill but it's also a great way to mingle and meet new people.

While you're at the club, party it up! The best way to improve is to dance with everybody, everywhere, anytime. You're just starting out? You're not expected to be Fred Astaire! Dance with as many people as you possibly can, and don't be afraid to ask that great dancer that you see in the club for a dance, or for some pointers. When asking people more advanced than yourself, be mindful of Salsa Etiquette for Beginners (which you'll learn in your Dance Class at www.dancesf.com). Even if you have a partner, don't only dance with them! It pays to learn to lead and follow from a variety of people, spread yourself around. You will learn FASTER!

While taking dance classes make sure you at least get out to a salsa dance club at least once a week (preferably more). Not only is it a blast to go out dancing, but in the beginning it can help reinforce those things you learn in class. Nothing is like some real world practice. It also helps you get used to the music which is played in the clubs, which by and large, is faster than what you will find in your typical salsa class! Check out Beginner Friendly Clubs listed on www.dancesf.com to find places to go out that are better bets for beginner dancers in the San Francisco Bay Area!

Cisco CCNA Certification Exam Tutorial: Keep Your Most Important Appointment

Imagine this. You have an appointment with a client to work on a server or router install. A few minutes before you're scheduled to be there, you decide there's something really good on TV you'd like to watch. Or you decide to go to the gym, or play a game, or do anything else except go see the client. Even if you weren't going to get fired for not showing up, it's certainly unfair to the client. You've got a professional obligation, and you should be there on time.

Now, what's this got to do with you becoming a CCNA or CCNP? Plenty. Because when it comes to your study time, you're the client. You owe it to yourself to show up. You would never blow off an appointment to meet a client to get some important work done.

First, though, you have to make that appointment with yourself! Schedule your CCNA / CCNP study time, and keep that appointment as you would with a client. Turn off the TV, your cell, your iPod, and everything else electronic that you carry around. Believe it or not, the world can survive with being in contact with you for an hour or so! You might even like it!

Getting certified isn't about how many hours, days, or weeks you spend studying. It's about how much quality time you put in. Be honest with yourself and realize that you're better off with 45 minutes of uninterrupted study as you would be with three hours of constantly interrupted study.

Don't blow off an appointment to yourself, either. Schedule the time, be there on time, get your study done, and you're one step closer to your CCNA and CCNP!

Cisco CCNA / CCNP Home Lab Tutorial: The 2503 Router

I know from experience that part of the excitement and anxiety of putting together your own CCNA / CCNP home lab is deciding what to buy! While you can make a workable home lab out of almost any combination of Cisco routers and switches, some routers are better suited for home lab work than others because they can fill multiple roles.

When you buy CCNA or CCNP "lab kits" - bundles of routers and switches - you can get a little confused about whether you're getting a good deal. One router I get asked about quite a bit is the 2503.

2503 routers are fantastic for CCNA and CCNP home labs. They come with two serial interfaces, allowing you to connect one interface directly to another router (you'll need a DTE/DCE cable for that, too) while connecting another to a frame relay switch if you like. If you don't have a frame relay switch, you can connect a 2503 directly to two other routers via the serial interfaces.

You also have an AUI port, which requires a transceiver to operate as your Ethernet interface. Transceivers are pretty cheap and readily available from Cisco resellers and ebay vendors, so pick one up for each 2503 you decide to buy.

2503 routers also come with a BRI interface. Even though you may not have an ISDN simulator right now, you may choose to add one later. That makes a 2503 a great bet for future lab expansion.

All in all, 2503 routers are great for your CCNA / CCNP home lab. They run about $125 each on ebay, or less, so they're also very affordable. There's no better training than training on your own CCNA or CCNP home lab, and you can always sell the equipment later if you like. Basically, you're renting the routers and switches, and the experience you get by working with the real deal is invaluable.

Cisco CCNP / BSCI Exam Tutorial: The Passive Interface Command And OSPF

To pass the BSCI exam and become a CCNP, you have to be aware of the proper use of passive interfaces. You learned about passive interfaces in your CCNA studies, but here we'll review the basic concept and clear up one misconception regarding passive interfaces and OSPF.

Configuring an interface as passive will still allow the interface to receive routing updates, but the interface will no longer transmit them. While the command itself would make you think this command will be applied at the interface level, that is not the case. Below, we'll configure ethernet0 as a RIP passive interface.

R1(config)#router rip

R1(config-router)#passive-interface ethernet0

Ethernet0 will no longer send RIP routing updates, but will accept them.

The passive interface concept is clear enough with RIP, IGRP, and EIGRP - all protocols that send routing update packets. But OSPF doesn't send routing update packets - OSPF sends link state advertisements. It's the inability of the passive interface command to stop LSAs that lead many to think that passive interfaces cannot be used with OSPF.

Even though OSPF does not sent "routing updates" in the form that RIP, IGRP, and EIGRP do, you can still configure an OSPF-enabled interface as passive in order to prevent OSPF traffic from exiting or entering that interface. No OSPF adjacency can be formed if one of the interfaces involved is a passive interface, and if you configure an OSPF-enabled interface as passive where an adjacency already exists, the adjacency will drop almost immediately.

Let's see that in action. R1 and R2 have an existing OSPF adjacency over their Ethernet interfaces. In an effort to reduce routing traffic, R1's e0 interface is configured as passive. The adjacency drops right away.

R1(config)#router ospf 1

R1(config-router)#passive-interface ethernet0

18:31:11: %OSPF-5-ADJCHG: Process 1, Nbr 2.2.2.2 on Ethernet0 from FULL to DOWN, Neighbor Down: Interface down or detached

Knowing how to use the passive interface command is a vital part of being a CCNP, and of being a master networker. Good luck to you in both of these pursuits!

Cisco CCNP / BCMSN Exam Tutorial: Dynamic VLANs and VMPS

Knowledge of Dynamic VLANs and VMPS is important in your efforts to pass the BCMSN exam and earn your CCNP, and it's also a great skill to have for your networking career.

As a CCNA and CCNP candidate, you know how and why to configure static VLANs. Static VLANs can be a powerful tool for reducing unnecessary broadcast and multicast traffic, but if hosts are moved from one switch port to another, you've got to make those changes manually on the switch. With Dynamic VLANs, the changes are made - how else? - dynamically.

The actual configuration of dynamic VLANs is out of the scope of the BCMSN exam, but as a CCNP candidate you need to know the basics of VMPS - a VLAN Membership Policy Server.

Using VMPS results in port VLAN membership changes being performed dynamically, because the port's VLAN membership is decided by the source MAC address of the device connected to that port. (Yet another reason that the first value a switch looks at on an incoming frame is the source MAC address.)

In my home lab network, I've got a host connected to switch port fast0/1 that resides in VLAN 12. What if we had to move Host 1's connection to the switch to port 0/6? With static VLANs, we'd have to connect to the switch, configure the port as an access port, and then place the port into VLAN 12. With VMPS, the only thing we'd have to do is reconnect the cable to port 0/6, and the VMPS would dynamically place that port into VLAN 12.

I urge you to do additional reading regarding VMPS. Use your favorite search engine for the term configuring vmps and you'll quickly find some great official Cisco documentation on this topic.

To review, the VLAN membership of a host is decided by one of two factors. With static VLANs, the host's VLAN membership is the VLAN to which its switch port has been assigned. With dynamic VLANs, it is dependent upon the host's MAC address.

Cisco CCNP/BSCI Certification: BGP Route Reflector Tutorial

When you're studying for your BSCI exam and CCNP certification, you quickly realize that BGP is a whole new world from anything you've previously studies. One topic that sometimes confuses CCNP candidates is when a BGP route reflector needs to be configured. Route reflectors are an excellent workaround for a basic rule of BGP route advertisement that we?ll review in just a moment.

In the following example, the routers R1, R2, and R3 are all in BGP AS 100. This is not a full mesh, however. There are peer relationships between R1-R2 and R1-R3, but not between R2 and R3. R3 is advertising network 3.3.3.0/24 via BGP, and the route is seen on R1. R1's iBGP neighbor, R2 does not see the route, nor would any other iBGP neighbors of R1. Why?

A basic rule of BGP is that a BGP speaker cannot advertise a route to an iBGP neighbor if that route was learned from another iBGP neighbor. Configuring R1 as a route reflector will allow us to circumvent this rule. The entire route reflector process is transparent to the clients, and no configuration is necessary on those clients. We'll configure R1 as a route reflector for both R2 and R3.

R1(config)#router bgp 100

R1(config-router)#neighbor 172.12.123.2 route-reflector-client

3d18h: %BGP-5-ADJCHANGE: neighbor 172.12.123.2 Down RR client config change

R1(config-router)#neighbor 172.12.123.3 route-reflector-client

3d18h: %BGP-5-ADJCHANGE: neighbor 172.12.123.3 Down RR client config change

The BGP adjacencies do come down when this configuration is added, so this isn't something you want to do during a peak traffic time.

Once the adjacencies come back up, R2 will have the route to 3.3.3.0/24.

There are other possible solutions to this iBGP limitation, such as configuring BGP confederations. Those solutions are generally used on larger BGP deployments and with other concerns in mind, though, and configuring route reflectors serves this purpose just as well.

Cisco CCNP Certification FAQ

To earn your CCNP, you've got to pass some very rigorous Cisco exams, and you also need to know the rules regarding this important certification. In this article, I'll answer some of the most commonly asked questions regarding the CCNP.

Q: What exams do I need to pass to get my CCNP?

A: You have two options, a three-exam path and a four-exam path. Currently, the four-exam path consists of rigorous exams on advanced routing techniques (BSCI), advanced switching (BCMSN), remote access methods (BCRAN), and advanced troubleshooting techniques (CIT). The three-exam path combines the BCMSN and BSCI exams into a single exam, the Composite exam.

Q: Do I have to take them in any order?

A: No, the order is up to the candidate. Most CCNP candidates take the BSCI exam first and the CIT exam last, but again this is up to the candidate.

Q: What else do I have to do to get the CCNP?

A: You must earn your CCNA before you can be CCNP certified (as well as passing the exams, of course).

Q: Is there a recertification requirement?

A: Cisco CCNP certifications are valid for three years. During that time, you must either pass the Composite exam, the BSCI and BCMSN exams, or pass any CCIE written exam.

Q: What if I don't recertify within the three-year period?

A: You must then meet whatever CCNP requirements there are at that time, from the beginning. It's easier to make sure you recertify!

Becoming CCNP certified is a great boost to your career and your confidence, and as with any Cisco certification, it's up to you to stay current with the CCNA and CCNP requirements. Visit the Career Certification section of Cisco's website regularly to learn about the program's requirements and changes.

Cisco CCNA / CCNP Home Lab Tutorial: The (Many) Cable Types And Their Purposes

One of the most common questions I get from CCNA and CCNP candidates who are setting up their own home labs is "What cables will I need?" The answer is "It depends." As you know from your exam studies, the physical layout of your lab is what determines the cables you'll need. Let's take a look at the most common home lab cable types and when you will need them.

Straight-through cables have quite a few uses in a CCNA / CCNP home lab. You'll need them to connect a switch port to an AUI port on a router (and you'll need a transceiver for that as well). If you have an ISDN simulator, straight-through cables can be used to connect a router's BRI port to the simulator.

Crossover cables are used to connect switches and allow them to trunk. If at all possible, get two switches in your home lab. This will allow you to gain valuable experience in manipulating root bridge election, working with STP, and creating EtherChannels.

DTE/DCE cables are used to connect two routers via their serial cables. If you are planning on using a frame relay switch in your lab, you'll need several of these. You can also get some great practice in by directly connecting two routers and bringing the connection up (and making sure it stays up!). This is valuable practice for your CCNA exam.

Octal cables are used to connect an access server to each of the other routers and switches in your lab.

Finally, there's that precious blue cable, the rollover cable. Rollover cables (sometimes called "rolled cables") allow you to connect a host device directly to a router or switch's console port. These cables have a way of disappearing around an IT shop, so make sure to take one home - and leave it there!

The Best Mexican Food Across The Country, Chosen By Mexican Restaurant Reviews From Boston To San Francisco

?You can?t get good Mexican food anywhere north of Texas.?

So averred my good buddy Tony when I suggested a Mexican meal on his recent visit. Now, I?m a good deal north of Texas, being in the Heart of Massachusetts, but that?s the kind of challenge that I can?t pass up. Three hours later, he was rubbing his stuffed belly as we left Tortilla Sam?s, voted Worchester?s Best Mexican Restaurant for the third year in a row. Being voted Best Mexican Restaurant in a little northeastern city may not seem like much ? till you stand in front of the window at Tortilla Sam?s and watch the tortillas ? freshly mixed and cut by hand ? roll through the steam press and catch a whiff of the mole. Then you realize that this is real Mexican food. And if the Mexican food in Worcester is good enough to impress Texas-born-and-raised Tony, we?ve got to figure that there are great Mexican restaurants in other unexpected places, right?

I went looking for the most out-of-the-way and unexpected places to find good Mexican food. My criteria and method were simple ? and hardly foolproof. In order to make the list, the restaurant must serve primarily Mexican food, and must have been voted a Best Mexican Restaurant in a local newspaper poll. There must be some mention in the review of authenticity. If there was a comment from someone who really KNOWS Mexican food, that gets bonus points. The list is a long way from exhaustive, but if you?re looking for good Mexican food a long way from home, you just might get your craving satisfied at one of these unlikely places to find authentic Mexican food.

Charlotte, N.C.

Me, I?d go looking for a good mess of pinto beans and Southern barbecue in beautiful Charlotte, but if I did have a craving for Mexican food, I?d head on over to Taqueria Las Delicias. It only took the #8 spot on AOL?s CityGuide City?s Best awards, but any place that serves its tamales wrapped in corn husk AND offers lesser known Mexican foods like pupusas and taquitos is going to get a visit from me when I hit Charlotte.

Boston, MA

The home of baked beans and clam chowder (white, thank you very much) is also the home to Andale!, a tiny restaurant that seats 8 at the counter. Forget the ground, slightly spiced meat mush that passes for Mexican food in most of Massachusetts, and build yourself a quesadilla from chunks of roast chicken and spiced vegetables. It?s fast Mexican food at its best, even if it is in Boston.

Philadelphia, PA

Next time I?m in Philly, I?m skipping the cheese steak and heading out for Mexican food. Voted Best Mexican food in the Philly area, Coyote Crossing in Conshohocken has all the standard gringo-Mex foods on the menu, but it also has? caramel crepes and homemade sangria.

Seattle, WA

Can I get a caf? latte to go with the chilies relleno? El Puerco Lloron in Seattle has been serving up its handmade tortillas and fresh salsa for over two decades and they?re still making the Best Of lists. If there is real Mexican food in the gateway to Alaska, chances are that you?ll find it here.

Baltimore, MD

The folks at the Baltimore Citypaper appreciate the irony of naming a Best Mexican Restaurant in Baltimore. To paraphrase, it?s like naming the best air conditioner salesman in Antarctica. Still, they dub the Mexican food at Los Amigos Mexican restaurant ?good? and the wait staff friendly. Not quite a ringing endorsement, but if I get sick of crab cakes in Baltimore, I know where I?ll go.

Cisco CCNA/CCNP Home Lab Setup: How To Configure Reverse Telnet

Occasionally, during your CCNA and CCNP studies, you'll run into a term that just doesn't quite make sense to you. (Okay, more than occasionally!) One such term is "reverse telnet". As a Cisco certification candidate, you know that telnet is simply a protocol that allows you to remotely connect to a networking device such as a router or switch. But what is "reverse telnet", and why is it so important to a Cisco CCNA / CCNP home lab setup?

Where a telnet session is started by a remote user who wants to remotely control a router or switch, a reverse telnet session is started when the host device itself imitates the telnet session.

In a CCNA / CCNP home lab, reverse telnet is configured and used on the access server. The access server isn't a white box server like most of us are used to; an access server is a Cisco router that allows you to connect to multiple routers and switches with one session without having to move a rollover cable from device to device.

Your access server will use an octal cable to connect to the other routers and switches in your home lab. The octal cable has one large serial connector that will connect to the access server, and eight rj-45 connectors that will connect to your other home lab devices. Your access server then needs an IP Host table in order to perform reverse telnet.

An IP Host table is easy to put together (and you better know how to write one to pass the CCNA!). The IP Host table is used for local name resolution, taking the place of a DNS server. A typical access server IP Host table looks like this:

ip host FRS 2007 100.1.1.1

ip host R3 2003 100.1.1.1

ip host R1 2001 100.1.1.1

ip host R2 2002 100.1.1.1

ip host R4 2004 100.1.1.1

ip host R5 2005 100.1.1.1

ip host SW1 2006 100.1.1.1

interface Loopback0

ip address 100.1.1.1 255.255.255.255

no ip directed-broadcast

This configuration will allow you to use your access server to connect to five routers, a frame relay switch, and a switch without ever moving a cable. When you type "R1" at the console line, for example, you'll be connected to R1 via reverse telnet. If you have a smaller lab, an access server is still a real timesaver and an excellent investment. And by getting a static IP address to put on your access server, you can even connect to your home lab from remote locations!
