Abstract

Engineering Teaching Kits, Experiments, and Demonstrations as Part of Workshops for Teachers to Facilitate Learning of Science and EngineeringXXX is an inquiry-based science and engineering program for P-12 students [1]. We havedeveloped, implemented, and evaluated educational materials (simple and inexpensiveexperiments that utilize easy-to-obtain materials) and pedagogical practices designed jointly withP-12 teachers [1, 2]. As part of this program, we have adapted (from the University of Virginia)as well as developed several experiments, demonstrations, and engineering teaching kits (ETKs).An Internet page with most of the developed materials is available [3].To promote our experiments, demonstrations, ETKs, and to further encourage theirimplementation in P-12 schools, our faculty presented several workshops at the Yucatanpeninsula. Around 250 teachers from the states of Campeche and Quintana Roo were engaged in2-day seminars, during which they attended several distinguished lectures and two workshopswhere they performed and learned how to teach more than ten experiments and demonstrationsas part of two ETKs, using recycled or inexpensive materials as tools to facilitate science andengineering learning.Experiments and demonstrations (planned to follow a guided-inquiry procedure) were includedin the workshops such as first, second, and third Newton’s Laws, effect of friction, Archimedes’principle, Pascal’s principle, among others. These were part of the ETKs entitled Racing Carsand Under Pressure [4], which are centered on Newton’s motion laws and density and buoyancyconcepts, respectively. Racing Cars include a tow engineering design challenge that requiresteams to use Newton’s motion laws concept to design a car propelled by air that advances amaximum distance while Under Pressure includes a design challenge to build a submarine ofminimum cost that achieves neutral buoyancy using a plastic bottle as a container as well as salt,sand, grave, beans, and/or rice to achieve required buoyancy. Teacher teams competed againsteach other. Thus the ETKs approach involved hands-on, inquiry-based, team-oriented projects.Information to report workshop outcomes was obtained from observational and interview fieldnotes from the formal sessions, participant workshop evaluations and an exit survey. Responsesto the survey indicated that the workshops were successful in preparing teachers and encouragingadoption of the experiments, demonstrations, and ETKs in Yucatan peninsula P-12 classrooms.Most teachers agreed that the experiments/demonstrations and ETKs are interesting and useful.In general, attendees rated them as good or excellent and felt very or somewhat comfortableperforming and teaching the experiments/demonstrations and ETKs after the workshops. Morethan 75% of the teachers plan to use experiments and/or demonstrations while more than 70% ofthe teachers plan to use ETKs. More than 90% of Pre-school, Kindergarten, and Elementaryteachers plan to use two or three experiments or demonstrations and ETKs in their classes, while70% of Middle and High School teachers will use only one or two and the ETKs. The writtenmaterials provided were rated as very helpful. The workshop provided participants withopportunities to interact more closely and to develop strong interpersonal relationships, whichare widely appreciated aspects of our program and valued highly by the teachers. In the paperactual experiences of some teachers after implementing workshops’ experiments,demonstrations, and ETKs in their classrooms will also be presented.[1] XXX (for blind review purposes)[2] YYY (for blind review purposes)[3] ZZZ (for blind review purposes)[4] Donohue, S.
