Manipulation of Light in the Nanoworld
Contributed by Boyang Liu on 26-OCT-07
Author(s) Seng-Tiong Ho, Ki Young Kim

Nanotechnology has become a globally popular and also a household name. The nanotech industry is rapidly expanding its territory of influence within last five years. However, it is surrounded by a state of confusion, because it is different from other tangible technologies of the past, and it lacks educational effort to promote the correct image to society. Therefore, more attentions and efforts should be paid on the Nanoscale Science and Engineering(NSE) education to link nano concepts to ever...

Nanocamp: An evaluation of student learning and an elaboration of student thinking
Contributed by Clara Cahill on 26-OCT-07
Author(s) Namsoo Shin, Joe Krajcik, Harold Short

Abstract: Summer nanocamp was designed to introduce middle school students to nanoscale science and technology, and to help them gain an understanding of some of its characteristic concepts. Activities were designed and adapted to help students develop and coordinate an understanding of size and scale, concepts important to size-dependent properties, and the tools used to observe micro and nanoscale objects. Additionally, students wrote their own nanoscience research questions, and created and...

Manipulation of Light in Nanoworld: Nanoplasmonics
Contributed by Maxim Sukharev on 25-OCT-07
Author(s) Joseph Yelk, Tamar Seideman

We present basic concepts of plasmon resonance phenomenon and nanoplasmonics for classrooms. Several interactive tools are developed using highly paralleled home-built FORTRAN90 codes to provide physical understanding of plasmonic physics at the nanoscale....

Summer Nanoscience Camp: Learning-Goals Driven Design and Evaluation Plan
Contributed by Clara Cahill on 06-JUN-07
Author(s) Namsoo Shin, Cesar Delgado, Shawn Stevens, Joe Krajcik, Minyoung Song

This poster details the learning-goals-driven planning and development of a Summer Nanoscience Camp for middle school students. The design of the camp takes into account the evaluation of the previous year's camp, as well as new research on students' learning progressions and common misconceptions. In the research-based, principled design, learning goals are identified and unpacked, and formative, embedded assessments are developed prior to or concurrently with the learning activities. We ou...

Classical Item Analysis in the Development of a Measure of Pre-service Elementary Teacher Understanding of Mass Density
Contributed by Eric Hagedorn on 23-MAY-07
Author(s) Eric A. Hagedorn, Sudheer Rakasi

Even after careful item generation?deciding the content domain, identifying sub-areas, considering item types, writing items, reviewing items, etc. an item analysis of pilot data is critical to the development of an instrument. This poster presents the item analysis of a mass density concept inventory, developed for use with preservice elementary and middle school teachers. This item analysis uses approaches from Classical Test Theory (CTT) such as: facility, delta, biserial and point biseria...

Manipluation of Light in the Nanoworld
Contributed by Boyang Liu on 18-MAY-07
Author(s) Ki Young Kim, David E. Ashkenaz, Seng-Tioing Ho, Jim Chen, Yeh Fei

The nanotech industry is rapidly expanding its territory of influence in the last five years. However, it is surrounded by a state of confusion, because it is different from other tangible technologies of the past, and it lacks educational effort to promote the correct image to society. Therefore, more attentions and efforts should be paid on the Nanoscale Science and Engineering(NSE) education to link nano concepts to everyday applications, close gap between cutting-edge research and Science, T...

Size and scale: An investigation of student conceptions of size
Contributed by Cesar Delgado on 05-MAY-06
Author(s) Shawn Stevens, Molly Yunker, Namsoo Shin Hong, Kelly Hutchinson, Emma Tervaarwek, Joe Krajcik, Nick Giordano

Scale is one of four "common themes" in the AAAS Benchmarks, which can unify content across grades, topics, and disciplines. Scale also underlies critical principles in nanoscience and technology. Considering widely varying ranges of variables (e.g., size) is the first step in learning about scale. This study investigates students' conceptions of size, including ordering (qualitative relative), grouping (categorical), how many times bigger one object is than another (quantitative relative), and ...
