PickleBall Unit

In the pickleball unit, we first learnt about the serving and the rules, I have completely understood the rules and how to serve a good serve. I later worked with my partner and we collaborated very well. I am now very confident to play a official pickleball competition with my partner and I improved a lot on serves and return this unit.

French Work: L4 Final Project

This oral presentation is related to the Unit of Health. In this task, I worked with Alexander and Kyle. We needed to write a script and then present it in front of the whole class by acting it out. Our script is about me getting into an accident, and Alexander calling for help from Doctor Kyle. We used past tense and vocabulary words in the script. While it was easy for my teammates and me to write the script, memorizing it and performing in front of the class is challenging.

My pronunciation is alright because I pronounced every word clearly and loudly, but I can still work on pronouncing it more accurately. To improve, I can continue to practice speaking every day and seek help from my teacher.

French Work: Writing Introduce Yourself Review

Presentation:

This work is part of a unit focused on reviewing previously learned knowledge. Its purpose is to assess my vocabulary, spelling, grammar, and writing skills. I needed to write a paragraph introducing myself and my family, using adjectives to describe them and their hobbies. This is an individual task. I chose this assignment because it requires multiple skills, such as grammar and vocabulary, to craft a well-written paragraph and achieve a good grade. I believe I have written an excellent paragraph that demonstrates my mastery of these skills.

This is my work:

Feedback and Reflection:

My teacher did not provide me with direct feedback, but she made several corrections to my paragraph, addressing issues such as incorrect word usage and spelling errors. For example, she highlighted my misspelling of “toujours,” which shows that I need to pay closer attention to my writing. Moving forward, I will continue to learn from these corrections and avoid repeating the same errors in the future. By doing so, I hope to improve my writing skills and produce clearer, more polished work.

Conclusion:

Overall, in this unit, I reviewed all the important skills and words I have learned over the past few years, which has prepared me for the upcoming unit and the new school year. I believe I can apply this knowledge frequently in real life, especially when I am asked to write something in French. I feel quite confident in reusing what I have learned because my vocabulary continues to grow in the new year, as do my writing skills. This growth not only enhances my ability to express myself clearly but also boosts my overall confidence in using the language effectively.

Integrated Mathematics 8 Semester 1

Active Learner Habits:

Strengths:

One strength I bring to math class is my organizational skills. I am always being prepared for class. I always bring my laptop, notebook and writing utensils.

Another Strength I bring is my collaboration skills. I actively collaborated with my teammates when there are team projects or questions that we need to solve together. I explained to other teammates with they don’t understand certain questions.

A Third Strength I bring is finishing works on time. I always finish my homeworks and check if it is correct when the answers are given. I also submit all the projects before the deadline and ontime.

Area of Improvements:

One habit I want to improve this semester is having neater notes in class. This is an area of growth for me because having neater notes would make it easier for me to review them while studying.

Plan for Growth:

I will work on this habit by writing or organizing my notes into Cornell notes, which would impact me to have easier and more efficient ways to study. One specific action I will take is to find a method to organize my notes for my learning and studying.

Math Notations and Communications:

My math work has improved because I drew I clear scatter plot with labeled X and Y axis and added neat descriptions on the newest notes while my old notes lack clear titles to make it easy to find.

Evidence of Understanding of Key Concepts:

Designing Your Story Problem:

My partner and I designed this story problem to create a real-world situation that requires solving questions using functions. This example demonstrates my understanding of functions, as I was able to create a problem and solve it using appropriate functional methods. I developed a complex linear function that makes sense within the context of the problem and provided a clear, step-by-step solution with full explanations.


This is the Sticker Project Unit, where we were tasked with designing a logo using transformations, dilations, and rotations. I designed a Real Madrid logo and wrote a detailed paragraph explaining each step of my process. I demonstrated how to perform transformations, dilations not from the origin, and rotations not from the origin, clearly showing my understanding of these concepts.

Overall, my work shows that I have a clear understanding of the math concepts taught in school and can apply them to real-life situations, and I feel very confident using all the skills.

Badminton Unit

In this unit, we played badminton. I am very good at singles badminton, however i am not very good at doubles badminton, through this unit, I worked with my partner trying to communicate and cooperate better when playing doubles. Now, my partner and i can play perfectly at doubles badminton. I also improved at serving, I can now serve low and short balls and long and far balls. Something I want to improve on is returning smashes, because usually when people smash, I can barely return it, so I really need to improve on returning smashes.

Designing a Story Problem( Piecewise Function Project)

1. Describe your story and what real-life situation it modeled.

The story is about Jordan, a rideshare driver who works a 5-hour shift on a busy Friday night. It shows how his earnings change throughout the shift based on different factors, like how many passengers are requesting rides and when surge pricing kicks in. This is similar in real-life, where the taxi is using more expensive in busy night time.

2. What part of your project are you most proud of? Why?

I am most proud of how I created the piecewise function to show Jordan’s earnings. It clearly breaks down his income during different parts of his shift, showing when he earns more and when he doesn’t earn anything.

3. What was the hardest part of creating your piecewise function?

The hardest part was figuring out the different time intervals for Jordan’s earnings and making sure I calculated everything correctly. I had to think carefully about when he was making money, when he was waiting without earning, and how the surge pricing affected his total earnings.

4. If you could revise one part of this project, what would you improve and how?

I would improve the graph that shows Jordan’s earnings. I think it could be clearer if I added more labels and made the lines different colors for each part of the shift. This would help people understand the changes in earnings better.

5. What did this project help you understand better about piecewise functions?

This project helped me understand that piecewise functions are useful for showing situations where things change at different times. I learned how to break down a story into parts and use different rules for each part.

Unit 2 Reflection and Semester Check-In

Part 1: Unit 2 Topic A and B Test Reflection (Functions & Statistics)

A. Evidence of Your Best Thinking

  1. I choose question 5 as evidence of my best thinking because question 5 requires a complete understanding of the residual plot, the scatter plot, and the skill to draw a line of best fit. I answered all questions correctly indicating I achieved all of the skills required.
  2. I choose question 7 as evidence of my best thinking becasuse question 7 is a exceeding question requires precise mathematical reasoning and understanding of the correlation, causation, and scatter plot. I wrote clear explanations answering each questions and got them all correct, suggesting that I also achieved all of the skills required.

B. Skills Reflection

Throughout Unit 2, I improved the most at drawing a scatter plot and a residual plot. I does not use scatter plot often, so after learning about scatter plot in this unit, I developed my understanding and can draw a good scatter plot. I also learned about residual plot in this unit, and how i can use it to indicate of the line is the best fit, or if the function chosen is correct.

    One skill from this unit that I still need to work on is interpreting the correlation coefficient in context and consider the difference between correlation and causation.

      The biggest challenge for me on this assessment was drawing a scatter plot and a line of best fit using only the residual plot. I think it is hard to draw a scatter plot and a line of best fit because it is sloped while the residual plot is flat.

        One strategy that helped me on this test was skipping the hard question and leave it at the end for me to do it.

        Part 2: Goal Reflection & End-of-Semester Check-In

        A. Looking Back at Your Last Goal

        Last Unit, i set this goal: I want to submit everything on time and earn a meeting for all of the assessments.

        How will did you work towards your goal?

        Very Well

        What helped you make progress toward this goal?

        To submit everything on time, I used organization systems to keep track of all my homeworks, and I review the key points for the test. The boba lottery review also helped my alot.

        B. End-of-Semester Self Reflection

        List three strengths you have shown last semester:

        Active Learning

        Functions

        Scatter Plot

          List three areas you still want to improve:

          Causations

          Critical Thinking

          Notebook Managment

          C. New Academic Goal Moving Forward

              In the next unit I want to earn more exceedings in celebration of learning and work with my groupmates more.

                What might get in the way of this goal?

                To earn more exceedings and work well with my groupmates, I may struggle with time management, group dynamics, and motivation. By prioritizing tasks and communicating clearly, I can overcome these challenges.

                  What will I do if I get stuck or need help?

                  I can ask my teachers to help me review before quiz, and create notecards to help me review keypoints.

                    Unit 2: Robotics

                    Jack.Zheng.8C2.Robotics.pdf

                    This project documents the full engineering process behind designing, building, and testing a robot for three competitive tasks in Design Technology: the Controller Race, the Wall Racer autonomous test, and the Stacking Challenge. Throughout the project, multiple iterations were made to improve speed, stability, power distribution, and functional performance. The work included constructing and adjusting different gear ratios, reinforcing the robot’s frame, optimizing wheel placement for stability, and developing functional mechanisms such as a front claw for block-pushing. Coding improvements—most notably the use of the inertial sensor—were also introduced to ensure the autonomous wall-racing robot could travel in a straight and consistent path. Each challenge required targeted design changes, systematic testing, and analysis of failures and successes. The final robot demonstrated mixed performance: it completed the required tasks but showed limitations in speed, alignment, and stacking capability, which were later evaluated through a functional test, SWOT analysis, and reflection. Overall, the project highlights the iterative nature of robotics engineering, where performance is continuously improved through testing, redesign, and problem-solving.

                    Unit 1: Tissue Box Design

                    Jack.Zheng.8C2.Thebox.V1.pdf

                    I am excited to present our Grade 8 Design class project at Shanghai American School (SAS) Puxi, where we are designing functional tissue boxes. Under the guidance of Jack Zheng, our project emphasizes innovation and addresses important community needs while also reflecting global design movements.

                    In this project, we are applying design principles in a practical context. We are using Inkscape for digital design and laser cutting technology for production. Our process includes thorough research, prototyping, and refinement to ensure our designs are both aesthetically pleasing and functional. We are working with materials such as plywood, acrylic, paper, cork, and spray paint to create tissue boxes that are durable and environmentally sustainable.

                    Our design inspiration comes from Modernism, which emphasizes simplicity and the idea that “form follows function.” This means we focus on clean lines and practical shapes, avoiding unnecessary decoration. Our goal is to create tissue boxes that not only prevent the spread of germs but also promote hygiene in communal spaces.

                    Through this project, we aim to demonstrate how thoughtful design can enhance daily life and contribute to health and environmental sustainability. I look forward to sharing our designs and the impact they can have on our community!
