Throughout my math career I have used many different types of software to promote learning. For this posting I decided to search for software that could have been beneficial to my practicum students last year since they are the only kids I’ve worked with so far. Also I wanted a find a program that I can hopefully use later in my teaching career.
I found a software program called “Graph Master” which is created by the Tom Snyder Productions Company which is part of Scholastic. As the title suggests, this software helps students with graphing different data sets and being able to manipulate the data in ways they could not do easily by hand. In our world today, the ability to interpret a graph is very important not to mention a big SOL for middle schoolers. Graph Master is designed for grades 4 – 8 and lets teachers the features as a way to build conceptual learning with real world applications.
The software includes nine different graph types that the students can use to display and manipulate their data. The graphs range from the simple bar graph to the more complicated box-and-whisker plots. It also gives student the chance to conduct research on their own and gather data to put into the program. Graph Master has a section where students can enter their own data into a chart and then choose which graph they feel best fits their data. Once the graph has been entered, students will also be able to label their graph and have a chance to interpret what the graph means. This is a huge part of the SOLs and being able to work with graphs in this manner would be extremely reinforcing to the student. Not only are they getting to play on computer but they are also learning in the process. There is also a section with pre-made data for the students to work with. There are ten different ready-made sets on various topics that the students can use. Having the data sets already made would save time and would be a better opportunity for the students to interpret the meaning. If they are the ones creating the data and graph, they will already have somewhat of an idea about what it means. Graph Master also has features that allow the student to manipulate the data by finding the mean, median, mode, range, sorting data, and create formulas for the data sets. These calculations are fundamental to math and the students need to understand how to find them. There is also a feature called ‘notebook’ where the students can compare data sets and graphs right on the computer screen. Part of the SOLs is for students to analyze and interpret graphs so having an area to express their thoughts is a good idea. Some other features include an online glossary that explains the terms used and how to analysis data, cross-curricular activities that are aligned with the NCTM standards, and a place to print the graphs created. Being able to print the graph would be a fun way for the students to present their findings with the data. Graphs can be easily incorporated into presentations this way.
I could not find an online demo of this program to play around with but there is a video on the website that goes through the features step by step and shows what the students are looking at as they go along. At the end of the video it says that the company offers a free demo for teachers and even parents to try out to see if they like the program. I might consider getting the demo just to see for myself if this software is something I would like to use one day with my own students if I decide to teach middle school. The program is a little pricey and probably is not something an individual teacher would want to buy for her classroom. Just to have the software on one computer would cost $79. However, the school could pay to put the program in one of the computer labs for the students to use for a better deal. I feel this program would be a good thing for a middle school or elementary school to have access too because of all the different features it lets the students do with graphing. Teachers can break the activities up and just have the students do certain functions on different days until the unit is complete. This program made me think about my practicum last semester. As I worked with my sixth grade class, I noticed several of them had trouble with creating and interpreting graphs during the statistics unit. I think if the students had the opportunity to work with the material visually on a computer they would have been able to understand the math behind the concept better. Being able to play on the computer while learning about graphing would be a good idea since these students would always get excited when my host teacher would plan computer lab activities. This would have let the students get a hands-on interactive experience working with graphs and hopefully be able to develop a better understanding of the concepts.

Jennifer,
ReplyDeleteI am a huge fan of this software! Though I have never worked with it personally, I went through the program software overview you provided in your post to see what I was like. I think this would be a perfect stepping stool software for upper elementary and middle school students working with graphs. I am currently in a college statistics course where we use Microsoft Excel to create all of our graphs. I'm 22 and still get confused with all of the things/steps you have to do to get to your end produce.
From the software overview, it was easy to see that Graph Master has 3 simple steps for creating a graph (insert your data into variable columns, select which variables you wish to compare in your graph, and select the graph type). Graph Master is much more explicit than Excel with how to create graphs, which is much more appropriate for younger learners.
Another feature that I really enjoyed about Graph Master were the different types of graphs you could create using the software. Using Microsoft Excel, you can create the standard pie, line, and bar graphs, but using Graph Master you can create box-n-whiskers, dot plots, and histograms! Students in Middle School are often times taught to draw these types of graphs by hand (since you can not create them in Excel). I think allowing students to create these types of graphs on the computer as well as practicing them by hand is a great way to solidify their understanding and increase their interest in the concepts. We need to recognize that the students in our classrooms live in a technology filled society and that it is important to appeal to the students interest which in return should help them learn the content.
Additional features of the software that I think would be helpful in the classroom are the 10 pre-made data sets already available in the software database to create lessons with, the option to compare two graphs (which is great for students to visually see similarities and differences between graphs in order to make conjectures), a notebook function where students can make comments about the graphs which are then saved with the data set, and additional cross curriculum data sets available for purchase through the software.
Overall, I am really fired up about this software and it is DEFINITELY something that I would incorporate into my Middle School Math classes. I might even take advantage of the free trial CD the website offered :)
Graph Masters sounds like great software to me, as well. I see students in upper elementary classrooms struggling with interpreting graphs, creating formulas and finding mean, median and mode of a data collection. One reason I think this might be is because it is an abstract concepts and often students do not get hands-on experience with manipulating graphs. Think this program would allow for student-centered activities and differentiated activities to meet the individual needs of each student. The fact that students can print the graphs they create is also a plus because then you they can take what they generated on a computer and share it with the class and/or use it as a studying resource.
ReplyDeleteOne example of how I would use the student created graphs is a partnered activity. Each student switches their print out with a partner and has their partner come up with a possible data set that the graph could represent. For instance a diagonal line, starting from the origin, could represent the speed of a car as it accelerates over time.
This looks like a great program! So far I have liked a lot of the Tom Snyder software programs, they seem to be interesting and educational, but I can see students getting excited about using them as well. I agree with Kelly, probably the best part of this program is that it includes all types of graphs, including box-n-whiskers, dot plots, and histograms. Even upper elementary students need to become familiar with these types of graphs, and this would definitely help with motivation. I also agree with Jessica, in that this doesn't have to be an individual computer time-- students could work with partners or small groups to evaluate their graphs, or poll their classroom or others in the school to collect data for other graphs.
