In a Digital Electronics class from the Project Lead the Way curriculum, high school students attempt to realize a set of logical relations for designing a voting booth privacy monitoring system. Throughout the sequence of the lesson, knowledge of theta is inscribed in different modal engagements: symbols and diagrams on the whilte board during the initial lecture, paper and pencil during small group design meetings, and a collection of materials fashioned and assembled into a projectile device, which was ultimately manipulated and evaluated.Ĭase #2: Logic Enacted Through Boolean Algebra, Simulation and Silicone: If these devices properly instantiate theta - that is, permit the adjustment of the angle of release while holding the other influential variables (e.g., initial velocity) constant - students will be able to predict the distance that the projectile will travel. Theta was a key variable that students had to represent both in their sketches, and ultimately in the materials they assembled into a catapult, trebuchet, gun or other ballistic device of their own choosing and design. On Day One of the lesson, the students learned the mathematics and physics of calculating projectile motion, and the teacher highlighted for them the angle of ascent of the projectile - labeled theta. ![]() The first case is of a high school Principles of Engineering classroom, part of the Project Lead the Way curriculum ( The case study focuses on a portion of a multiday lesson on ballistics, where the students use mathematics (trigonometry and algebra) and physics (kinematics) to calculate the distance a projectile will travel under certain conditions. ![]() ![]() the stability of mathematical knowledge across contexts produced and enforced “locally” to the agents, time and situation), so they serve as a common thread of coherence through STEM activities.Ĭase #1: Theta in Symbols, Paper and Wood:Ī Ballistic Device Design in a Precollege Engineering Classroom on Mechanical Engineering Many aspects of curriculum and instruction observed across these cases of science, technology, engineering and mathematics (STEM) education exist in order to engage relation-production mechanisms to advance students’ perceptions of locally invariant properties (i.e. The three cases illustrate how teachers and students manage the process of threading mathematical concepts across ecological contexts. The case studies presented in this section are from three high school classrooms: (1) a Principles of Engineering class designing and building ballistics devices, (2) a Digital Electronics class building digital circuits for a secure voting booth, and (3) an advanced Geometry class exploring properties of angles inscribed in circles using dynamic geometry software.
