• The process of designing curriculum is quite useful as it details how different activities correspond to learning goals in science, mathematics, and technology. Fig. 3 describes the steps: selecting content through content specialists in the POAC team, making a curriculum outline, individual meetings with content specialists, and making the lesson plans. I really like the activities they designed, such as comparing different mask materials and how they protected against differently-sized viruses. They were also given time to research career pathways and present on epidemiology careers, a step that invites students to imagine career pathways. 

• I realize the scope and audience of this paper is different, but I am so curious about how the Imhotep Academy created a setting that encouraged underrepresented students to participate and speak up, given that they cite evidence of how difficult that can be. How did they choose participants? 

• Having read Freire’s Pedagogy of the Oppressed recently, I am thinking about his approach to curriculum design that is based on a feedback loop between would-be learners and would-be educators. The roles of learners and educators aren’t fixed. Content development is not done beforehand just by content specialists but in an iterative process with multiple feedback loops. Since very few research teams have the time or the resources to deploy Freire’s rigorous approach, I am not surprised that most curriculum development does not follow the route. And educators are working with former experiences anyway. So I am curious about how the authors’ previous experiences shaped their approach to curriculum design?

• A context for this paper is the controversy on the proposed revisions to the California math curriculum that conservative media outlets argue “waters down” calculus–a cherry topping on the college admissions cake–to privilege data science in middle-school grades. Education researchers contend that apart from physics and engineering majors, not many colleges actually require calculus for admissions (many private institutions do), and that the relevance of advanced calculus for college preparation is overrated.

Smart autoalarm guardrail is designed for helpping people emergency contact and remind the other drivers when car accident happen in remote area. People will drive on some remote area, or late night. If car accident happens, might be no one know the accident is happen. This design is help the litigant automatically make a emergency call, and send the location through the GPS when the car is crash the guardrail. As well as, it can turn on/flash the light within the accident area to warn the other drivers. 

Smart guardrail is concept design by Yuguo chen and Changlin He, who are from School of Design, Hunan University in China. 

This design could help people in an unknow emergency situation, for example, the driver pass out when the traffic accident happen, and this design can help people to save life. However, I think this concept design might be cost a lot if it is applied into real life, because it means there are lots of guardrail need to install this system, and the government also need to prepare another extra fee for repair the guardrail after every accident. 

The smart guardrail is designed to be used in some remote area and highway. 

Smart Guardrail is autoalrm and could be send location to the nearset emergency centre by GPS when the car crash into the guardrail. As well as the warning light within the area will be swithched on to avoid the potential sencond accident. The system is design to install into the highway guardrail, and use the circuit to make the system work. Therefore, the materials might be include electrical wire and circuit, and also plastic caution lights.

This concept design is supposed to install on the highway guardrail and work automatically in a pubilc area, therefore there is no specifically skill need to learn. 

Smart Guardrail is considered as a good concept design, because it can be solve the emergency problem for traffic accident in some situation. This design is applied a common materials and method to solve problem. It is a small change and might make a big influenced. But the design could be used or not is depend on the cost would be proportional to the value or not.

This concept design is create a market which is within more functions and technologies for guardrail. In the existing market, there are some good design highway guardrail, such as EZY-guard smart guardrail. Most of the existing product are applied outter shapes and physical structures rather than some electrical technology. Compare to the existing products, this concept design is more challenged by the cost.
