research can promote retention for a variety of reasons. V. Tinto et. al.1 reportedthat students often fail to graduate due to a lack of persistence, rather than due to lack ofintelligence or ability. Being familiar with “hands-on” technology in a laboratory where theybecome familiar with current equipment boosts self-confidence2. Participation in research groupscan promote persistence in a variety of ways, in part by increasing personal attachment to theresearch group and the research objectives. Secondly, the mentoring process inherent in therelationship between the research supervisor and the student researchers permits identification ofproblems at critical junctures.

The selection of STSE andTeacher Identity have been informed by my own experience conducting research withpre-service and new science teachers, and their use of an STSE approach in their teachingof science.

inTable 1. As shown, 84% of the total grade was assessed during scheduled class and laboratorytime. Since attendance was mandatory, few would miss any of the in-class graded events. Thisprompted a focus of short-term preparation since quizzes, exams and the term-ends were allscheduled events, while assignments were less emphasized because they were simple, time-demanding, worth few points and provided with solutions at a later time.To overcome this procrastination in this course, the author proposed two objectives: shift pointsfrom in-class to out-of-class events and reduce the total number of events.

This technology makes it possible to create microfluidicdevices with any planar (2D) design that the students can draw on a paper. After the drawing isfinished, it takes only 1 hour to fabricate a microfluidic device with the shape of that drawing.We believe that this technique will enable the study of microfluidics in educational settingslimited in their access to cleanroom facilities.

The laws are relationships of the system, in this case: 1) The area of any rectangle is the product of its length and width and 2) the perimeter is twice the sum of the length and width.Call the length, L, the width, W, the area, A and the perimeter, P. Then in algebraic notationthese laws become: 1) A = LW and 2) P = 2(L + W). This algebraic notation is a wonderfulinvention. Not only are laws written more compactly in algebraic notation, but the algebraicnotation is easily manipulated. The relationship, A = LW, can also be modified by the rules ofalgebra to L = A/W
