My Choice For My School
In late 2017, I chose to lead my school in the direction of purchasing Pasco Scientific probeware. At the time we had some funds available, Vernier did not have equivalent equipment for sale. In addition, a big draw for me was Pasco’s Smart Carts. As an 8th grade teacher, physics is an important part of the year and having a smart dynamic track (I.E. Pasco Wireless Smart Cart) was a big draw. At the time, Vernier had nothing close.
In 2017, Pasco had a clear lead with Bluetooth sensors for the classroom. At the time, Vernier had very few Bluetooth sensors, and was more known for their LabQuest data loggers and sensors.
In my opinion, graphical data loggers were more relevant before every student had a smartphone in their pocket. Vernier’s LabQuest 2 device costs $329.
With these Bluetooth devices, I can rely on student’s smartphones and let students see how their phone can be used to solve real world problems. Logging the data to their own device means they have control of the data (no worries about the next class deleting it) and can analyze it in class or at home.
For the inevitable group or two that doesn’t have a phone, I make my old iPhone available, and I purchased an Amazon Fire Tablet. Both run Pasco’s SPARKvue software quite well.
Vernier has been introducing quite a few new products at competitive price levels making the decision of what brand to buy more difficult. In every category above, Pasco and Vernier have equivalent equipment priced competitively.
If you are buying probeware for the first time, here are a few points to consider:
- Do you use DonorsChoose.org?
- Vernier equipment is easily available through standard suppliers. Both Wards’ and School Specialty are approved vendors and carry Vernier equipment.
- Pasco equipment requires a “special request” which requires teachers to have 6 “points”. See details here. Pasco had asked to be added as a vendor to DonorsChoose, but there is no timeline for that happening.
- Pasco is less expensive for equipment.
- Vernier provides free software for all platforms.
- Pasco provides free software for iOS and Android, but charges a $200 site license fee for Windows and Mac software.
- My Pasco rep promised me a free license for my middle school for their “Capstone” software if I purchased over $1,000 of equipment. I purchased over $4,000 of equipment this year, so I was rather surprised when I was told “NO” they would not honor that promise.
If you already have some probeware, I suggest sticking to your current vendor. The hassle of having to know and use two different data logging software systems is not worth it.
