The integration of nano-science and technology concepts into upper-division high school and lower-division college curricula will require innovative educational approaches that will help students understand the structures and properties of matter on a scale below 100 nanometers, i.e., the nanoscale. This Interactive Nano-Visualization in Science and Engineering Education (IN-VSEE) project will create a consortium of university and industry researchers, community college and high school science faculty, computer scientists and museum educators with a common vision of creating an interactive World Wide Web (WWW) site to develop a new educational thrust based on remote operation of advanced microscopes and nanofabrication tools coupled to powerful surface characterization methods. The centerpiece of this project is the web-based operation of the revolutionary scanning probe microscope (SPM), which has evolved rapidly into a relatively simple, yet powerful, technique capable of imaging and manipulating materials at resolutions down to the atomic scale.

OCLI is a leading manufacturer of thin films for optical and thermal control applications. The determination of thin film and substrate topography can be a powerful way to obtain information for deposition process design and control, and about the final thin film device properties. At OCLI we use a scanning probe microscope (SPM) in the analytical lab to obtain qualitative and quantitative data about thin film and substrate surfaces for applications in production and research and development. This manufacturing environment requires a rapid response, and a large degree of flexibility, which poses special challenges for this emerging technology. The types of information the SPM provides can be broken into three categories:(1)Imaging of surface topography for visualization purposes, especially for samples that are not SEM compatible due to size or material constraints;(2)Examination of sample surface features to make physical measurements such as surface roughness, lateral feature spacing, grain size, and surface area;(3)Determination of physical properties such as surface compliance, i.e. “hardness”, surface frictional forces, surface electrical properties.

A modification of the Paired-Stimuli Parent Program (Florance, 1977) was adapted for the treatment of articulatory errors of visually handicapped children. Blind high school students served as clinical aides. A discussion of treatment methodology, and the results of administrating the program to 32 children, including a two-year follow-up evaluation to measure permanence of behavior change, is presented.

Summary: This article describes a triarchic analysis of an aptitude-treatment interaction in a college-level introductory-psychology course given to selected high-school students. Of the 326 total participants, 199 were selected to be high in analytical, creative, or practical abilities, or in all three abilities, or in none of the three abilities. The selected students were placed in a course that either well matched or did not match their pattern of analytical, creative, and practical abilities. All students were assessed for memory, analytical, creative, and practical achievement. The data showed an aptitude-treatment interaction between students' varied ability patterns and the match or mismatch of these abilities to the different instructional groups.

This study examined how social opportunity structure influences identity exploration and commitment of Albanian high school students. A total of 258 students completed a questionnaire that gauged their identity exploration and commitment in three domains: education, occupation, and family. ANOVA results indicated that, overall, students scored highest in exploration in the domain of education and in commitment in the domain of family. Students' exploration and commitment were linked to gender. Albanian female students scored higher than male students in exploration and commitment regarding education and family. Perceived work opportunities in Albania or abroad also significantly moderated participants' exploration in the domain of education and were associated with commitment in education and occupation. As one of the first studies to explore Albanian youth's identity development in relation to social opportunity structure, findings are discussed in light of furthering the field of Albanian adolescent and youth development.

Abstract. This study investigated the effects of politicians’ nonparticipatory and participatory Facebook posts on young people’s political efficacy – a key determinant of political participation. We employed an experimental design, using a sample of N = 125 high school students (15–20 years). Participants either saw a Facebook profile with no posts (control condition), nonparticipatory posts, or participatory posts. While nonparticipatory posts did not affect participants’ political efficacy, participatory posts exerted distinct effects. For those high in trait evaluations of the politician presented in the stimulus material or low in political cynicism, we found significant positive effects on external and collective efficacy. By contrast, for those low in trait evaluations or high in cynicism, we found significant negative effects on external and collective efficacy. We did not find any effects on internal efficacy. The importance of content-specific factors and individual predispositions in assessing the influence of social media use on participation is discussed.
