Sensor data collection for class projects

RPi-Logo-Stacked-SCREEN

Collect data with sensors for classroom exploration.

Involving students in the first step of the data collection process promotes engagement and interest.

It’s hard to collect accurate data in the real world. Students must learn to be aware of different variables that impact readings and to harness their critical thinking skills to troubleshoot often.


Raspberry Pi
Raspberry Pi is a small, microcomputer processor with an average cost of $25-$35. This simplistic device can be outfitted with different sensors, including those that measure temperature, moisture, humidity, and so much more.

Without a keyboard or monitor, the Raspberry Pi can be set up in any location in a classroom and take measurements of sensor data at requested intervals.

Once collected, data can be downloaded and used for analysis.

Hawkes is using these devices to set up several experiments to provide a live data feed for free use, and you can too!


Here are 3 ideas for experiments that we have in the works using Raspberry Pi:

1. Bamboo growth
Follow how quickly different bamboo plants are growing and what impacts their growth. You can also check out the cool sensor data PiPlanter is collecting, including soil humidity and ambient light, to create a clever irrigation device!

2. Air quality control
Track carbon monoxide emissions and see how the readings change as distance to humans varies.

3. Temperature
Assess temperature in different locations of the room. Watch out for variables such as air conditioning drafts, sunlight, and proximity to people and computers.

2 videos to kill math intimidation

Students fear failure and, too often, math.

What are two things that can help?


1. A mastery-based approach to learning
The word “mastery” gets thrown around a lot, but it’s not just a word to us at Hawkes Learning; it’s the core of what we do.

This type of learning ensures students with different skill sets understand the same material by adapting to their needs and providing additional support for those who require more time.

A mastery-based program should set clear goals for students, hold them accountable for achievement, and reward them fully for success.

Discover why Hawkes’ approach works:

2. Detailed, error-specific feedback
Most students don’t see that mistakes are learning opportunities rather than evidence of not being a “math person.”

The Explain Error tutorial diagnoses exactly where students went wrong on a problem. It explains specific errors and allows students to learn from their own mistakes in real time, answering the most important question: Why am I wrong?

You focus on teaching. Let us provide the data.

The new Discovering Statistics and Data text offers 36 (and counting!) real data sets for free download.

Data Set Obesity

The companion website to the new Discovering Statistics and Data textbook, stat.hawkeslearning.com, supplies updated and relevant data sets, instructions on computational technologies, and access to data visualization tools and websites.

These large data sets expose students to the kind of real-world data they will encounter in their future careers. With so many variables and data points included, students must learn to work the data and make meaning from all the information provided.

This free online resource from trusted sources shows how interesting exploring data can be. Students will learn to work with raw data and draw meaningful conclusions.

Exercises in the new Discovering Statistics and Data textbook refer to the data sets provided on this curated website.

Teaching a corequisite statistics course?
The new Discovering Statistics and Data + Integrated Review emphasizes the importance of data in today’s world and is designed to provide all developmental math content needed to support statistics learners.

Stop Cheating on Calculus Homework

Cheating Image

2 Advantages of Homework Software

Learning math requires the repetition of solving problems until the concept is learned.

Consider two advantages of software over a traditional paper-and-pencil approach:


  1. Eliminate cheating by copying out of the back of the book.
    Software has the ability to provide students with their own unique homework assignments with algorithmically generated questions. This will completely eliminate the former methods of cheating on homework by copying out of the book or copying a neighbor’s paper.
  2. Provide unlimited practice for students.
    Software can give students unlimited practice problems and even practice testing options, whereas a textbook only contains a finite number of exercises and examples. Practice makes permanent.

Calc Book and ComputerHawkes Learning’s NEW Calculus with Early Transcendentals courseware provides learning modules with unlimited practice opportunities & unique, algorithmically generated questions.

Reducing Algebra as a Calculus Pain Point

Time and time again, we hear from calculus professors across the country that one of the biggest issues in their classes is students remembering the building blocks of algebra.

Here are a few suggestions to help ensure students have the basics mastered:

Consider diagnostic testing.

Identify students who have skill gaps, then provide them with supplemental assignments in the first weeks of class for additional support.

Ask students who excel on the diagnostic test if they are willing to be course mentors, which will build classroom camaraderie.

If possible, host a 1-day algebra refresher workshop before the first day of class.

Begin the term explaining how algebra is foundational to calculus. Let students know they are not alone in struggling with algebraic concepts. Hosting an algebra refresher will help students feel more comfortable asking questions.

Remind students that you’re grading for accuracy.

Feedback is critical for students to realize they are struggling. If time permits, set aside a few minutes after passing back assignments so students can look over the feedback you gave them and ask questions.

Provide every student with technology resources as further help.

List out a few tech resources that are easy to access, such as YouTube videos or online interactive games, on your syllabus. Additionally, look for calculus materials that provide a brief algebra refresher as part of the text.


Hawkes Learning’s Calculus with Early Transcendentals textbook and NEW courseware offer exercises and diagnostic testing that target the key algebraic topics calculus students need to master. Request a complimentary exam copy.

5 Ways to Get Students Interested in Statistics

Creating a universally engaging classroom environment can be challenging, but having the right tools that make lesson content relevant to students helps! Below are 5 ways to get your students more excited about statistics:

1. Interesting Data
Finding data on topics students think are fun, like beers and breweries across the country, might pique interest. Use this spreadsheet from the U.S. Census to show them socioeconomic trends they may witness themselves in their own demographic (or age bracket).

2. Visualization Tools
Seeing is believing. The free online resource Gapminder offers a graphical simulator depicting 5 dimensions of real-world data in 2D. Students can change the relationships between demographic, economic, and societal variables animated over time to see some pretty neat relationships in motion.

3. Applications Challenge
Knowing the immediate value of the lesson they’re learning gives students more encouragement to commit the content to memory. Asking students to find their own data sets on their favorite sports team or something they connect with might engage their interest and help them truly grasp the concepts.

5 ways to makes stats more relevent

4. Games
You know statistics can (and is!) fun, and who doesn’t like to win? Interacting with a game and trying to win it make learning more exciting. View some examples of statistics games here.

5. Simulations
Help students grasp key concepts through simulations that hold their attention! Use simulations in class and encourage students to work through as a group to liven up the lecture time. Check out fun simulations here.
