The learning of linear functions is pervasive in most algebra classrooms. Linear functions are vital in laying the foundation for understanding the concept of modeling. This unit gives students the opportunity to make use of linear models in order to make predictions based on real-world data, and see how engineers address incredible and important design challenges through the use of linear modeling. Student groups act as engineering teams by conducting experiments to collect data and model the relationship between the wall thickness of the latex tubes and their corresponding strength under pressure (to the point of explosion). Students learn to graph variables with linear relationships and use collected data from their designed experiment to make important decisions regarding the feasibility of hydraulic systems in hybrid vehicles and the necessary tube size to make it viable.

The purpose of this Guide for Culturally Responsive Practice is to provide educators and educator teams with questions and protocols to guide and/or reflect on how to apply culturally responsive instruction practices as they address learner variability. Learner variability is a recognition that all students differ, and that learning sciences research guides us in understanding how these differences matter for learning. It embraces both students’ struggles and strengths. It considers the whole child—academic, social-emotional, and student background. When people understand learner variability, they see a design challenge, not a student problem.

This unit engages students in a variety of activities that analyze and reflect on the role of social media in our everyday lives. This includes options for collaborative group work, reading nonfiction articles, a design challenge and presentations to communicate ideas. The unit also includes a formal writing assessment option that aligns with the Common Core State Writing Standards. Activities can be adapted or combined in a variety of ways to support student reflection and analysis. These lessons were piloted in 9th grade English classes but are suitable or a range of secondary students. 

Students make two different formulations of imitation Silly Putty with varying degrees of cross-linking. They witness how changes in the degree of cross-linking influence the putty properties.

Students use latex tubes and bicycle pumps to conduct experiments to gather data about the relationship between latex strength and air pressure. Then they use this data to extrapolate latex strength to the size of latex tubing that would be needed in modern passenger sedans to serve as hybrid vehicle accelerators, thus answering the engineering design challenge question posed in the first lesson of this unit. Students input data into Excel spreadsheets and generate best fit lines by the selection of two data points from their experimental research data. They discuss the y-intercept and slope as it pertains to the mathematical model they generated. Students use the slope of the line to interpret the data collected. Then they extrapolate with this information to predict the latex dimensions that would be required for a full-size hydraulic accumulator installed in a passenger vehicle.

You are part of the NASA design crew and your task is to design a suit to keep the human body safe from the hazards of deep space. Are you up to the challenge? This is an ADA compliant document.

This is an activity about spacecraft design. Teams of learners will model how scientists and engineers design and build spacecraft to collect, store, and transmit data to earth. Teams will design a system to store and transmit topographic data of the Moon and then analyze that data and compare it to data collected by the Lunar Reconnaissance Orbiter .

In this video segment adapted from ZOOM, cast members make a seismometer and experiment with different ways to make it register movement.

This activity focuses on the relationship between science of looking for life and the tools, on vehicles such as the Mars Rover, that make it possible. Learners will create their own models of a Mars rover. They determine what tools would be necessary to help them better understand Mars (and something about life on Mars/its habitability). Then they work in teams to complete a design challenge where they incorporate these elements into their models, which must successfully complete a task. Teams may also work together to create a large-scale, lobby-sized version that may be put on display in the library to engage their community. The activity also includes specific tips for effectively engaging girls in STEM. This is activity 6 in Explore: Life on Mars? that was developed specifically for use in libraries.

As part of a design challenge, students learn how to use a rotation sensor (located inside the casing of a LEGO® MINDSTORMS ® NXT motor) to measure how far a robot moves with each rotation. Through experimentation and measurement with the sensor, student pairs determine the relationship between the number of rotations of the robot's wheels and the distance traveled by the robot. Then they use this ratio to program LEGO robots to move precise distances in a contest of accuracy. The robot that gets closest to the goal without touching the toy figures at the finish line is the winning programming design. Students learn how rotational sensors measure distance, how mathematics can be used for real-world purposes, and about potential sources of error due to gearing when using rotation sensor readings for distance calculations. They also become familiar with the engineering design process as they engage in its steps, from understanding the problem to multiple test/improve iterations to successful design.

Multilinguals, those of us who use more than one language in everyday life, are... gifted semilinguals who are dominant in no mother tongue, for example? Apparently so, judging by the ways people keep talking about them. This is the first book that discusses, in light-hearted lay terms, the reasons behind the beliefs and myths about multilinguals that allow you to fill the blank in its title with almost any label and get away with it. Drawing on solid academic research, the book provides keys to the origin and endurance of the many intriguing names that multilinguals have been called, starting with the master-key to them all. The conclusion is that any oddities assigned to multilinguals are due to the language that is used to talk about them, not to multilingual behaviour itself. The book is abundantly illustrated and includes many cartoons. It is written for the general public, families, teachers, policy-makers, clinicians, and anyone who ever wondered about multilingualism, but is targeted exclusively at multilingual or monolingual readers (of English).

Students' understanding of how robotic touch sensors work is reinforced through a hands-on design challenge involving LEGO MINDSTORMS(TM) NXT intelligent bricks, motors and touch sensors. They learn programming skills and logic design in parallel as they program robot computers to play sounds and rotate a wheel when a touch sensor is pressed, and then produce different responses if a different touch sensor is activated. Students see first-hand how robots can take input from sensors and use it to make decisions to move as programmed, including simultaneously moving a motor and playing music. A PowerPoint® presentation and pre/post quizzes are provided.

This is a template intended to be used by participants in the OER Design Challenge to copy, remix, upload and insert media, write, describe, align to standards, license and publish their remixed OER.

Developing a course, and associated materials, to support professional development can often be a costly enterprise. Designers and developers need to consider curriculum design, materials development, quality assurance, platform customisation and evaluation. Following this process step by step is often protracted and costly. The ADDIE model of instructional design, a popular and often cited ideal approach to creating courseware, suggests that analysis of needs, courseware design and development, implementation and course evaluation is required by any entity bent on creating effective courses.

In contrast to this mindset, however, there is evidence that a collaborative-shared approach to instructional design challenges the ADDIE model’s assumption that each step needs to be done in-house. Since 2011, several Teacher ICT Integration professional development initiatives around the globe have demonstrated that burdens in both design and development phases can be shared, shortening the time required to design courses and develop the accompanying resources. This approach also is more cost effective than typical ventures.

In this field exploration, student teams (consisting of 3 students) will investigate whetherincandescent, fluorescent or a no light situation will attract the most nocturnal insects.
