One of the experiments that made me passionate about physics was the Roller Coaster Experiment in 9th grade, which introduced the concepts of potential and kinetic energy through a hands-on activity. By participating in the activity with a visual tool, I was able to see how energy transformed as the roller coaster moved along the track and how height and speed were connected while manipulating variables. That experience helped me understand the power of learning by doing, and it strengthened my interest in studying physics more deeply. I aim to achieve the same objective with this mission project.
Ms. Walker is an FDR middle school science teacher who teaches 6th-grade and 8th-grade students. I chose her to interview because she is an expert in science education and she is knowledgeable of our middle school's curriculum. Although the original plan was to conduct the interview in person, due to scheduling difficulties, it was conducted via Gmail.
Inquiry questions asked include:
What physics concepts do middle school students usually find most difficult?
From your experience, which learning methods (visual, hands-on, etc.) are most effective for helping students understand these concepts?
Are there any scientific concepts you feel currently lack enough accessible learning resources?
For the first question, she explained that the concepts middle school students struggle with the most are connecting math with physics. As math is an essential and significant part of learning physics, this difficulty becomes a major obstacle for the students. She emphasized that students often have trouble with scale, proportions, ratios, and fractions. More importantly, she identified Newton's second law of motion and calculations involving speed as particularly difficult for students. Her responses helped me understand that my tool must address both mathematical reasoning and the physics concept.
For the second question, Ms.Walker highlighted that direct instruction is very effective. After students get the basic ideas, hands-on activities and data collection help reinforce the concepts. Notwithstanding, she warned that students sometimes treat hands-on activities as play rather than a learning opportunity. This means that the instructional tool must be designed to ensure academic engagement.
For the last question, she noted that the accessible resources for analyzing data and creating graphs are limited. Middle school students need more practice in interpreting data sets and constructing data.
Overall, Ms.Walker's feedback provided valuable information refining my idea and guiding future paths. It underscored the importance of the math-concept relationship and the need for clear, structured data analysis. Based on her suggestions, I decided to design a tool that focuses on Newton's second law, provides further space for math calculation, is interactive and engaging, and has clear instructions.
Ms. Castro teaches coding and robotics at FDR High School, making her an expert in robotics, including Arduino. The interview was conducted in person on November 21.
After explaining my mission project to her, she suggested integrating my learning tool with Arduino, especially the Nano board. After researching existing products, such as Speed Detector, she guided me on what components I would need and how Arduino works.
To enable students to manipulate variables and perform mathematical calculations, the Arduino will measure the time and speed of an object. These measurements require specific Arduino sensors and components: an Arduino Uno (or Nano), an IR Obstacle Avoidance Sensor Module, breadboards, an LED (to visualize if the object passes a certain point), a Liquid Crystal Display, and resistors (to resist the flow of electrical energy in a circuit).
Ms. Castro's feedback and information were invaluable for the project, as Arduino played a major role in it. Moreover, she provided me with the required materials and a tutorial book (used for Benchmark 2).
Note taken during the interview
The research conducted for this mission project provides valuable information and overall support for the idea of a manipulable learning tool to overcome students' difficulties in middle school physics. Results show that the most difficult concepts for students to understand in middle school physics are abstract, such as energy transfer and conservation, and forces, particularly the major misconception that constant motion requires continuous force application. Furthermore, it is important to note that the concept of friction is usually neglected. One example study was an inclined plate system, which is an effective platform that fits with inquiry-based learning that allows students to directly observe and measure the changes that manipulating variables such as surface material and angle have on motion.
The ability to apply mathematics to physics, particularly with regard to Newton's Second Law and speed calculations, has been highlighted by expert interviews as problematic. This information demonstrates the path my tool should take. The research proved that the Arduino is the best platform for accurately measuring variables such as speed, as it is simple and well-suited for hardware control of repetitive tasks. This system will also include components such as an IR Obstacle Avoidance Sensor Module and a Liquid Crystal Display to accurately measure and display times and movement data. The insight into incorporating technological aspects with scientific aspects would greatly benefit my project.
In all, the final project will be a plate kit that addresses both common misconceptions, such as Newton's second law and mathematical calculations, simultaneously. Focusing on a modular design to demonstrate friction and incorporating Arduino technology to give structure to data analysis, my product will effectively engage students because it contains manipulative variables and it will accurately correlate with the science curriculum. Based on the research, the following phases are designing and building.
