Writing and genre scholarship has become increasingly attuned to how various nontextual features of written genres contribute to the kinds of social actions that the genres perform and to the activities that they mediate. Even though scholars have proposed different ways to account for nontextual features of genres, such attempts often remain…

Research has highlighted difficulties experienced by students when studying quantum physics in introductory courses. In this paper, we present a teaching and learning sequence (TLS) aiming at introducing a quantum model of emission and absorption of radiation and we assess its impact on the students' learning about atomic spectra. The TLS has been…

Climate change is one of the most critical problems facing citizens today. Chemistry faculty are presented with the problem of making general chemistry content simultaneously relevant and interesting. Using climate science to teach chemistry allows faculty to help students learn chemistry content in a rich context. Concepts related to…

Conceptual Change is a widely accepted theoretical framework for science education. Setting up successful learning and teaching arrangements in this framework necessarily entails including students´ preconceptions into the construction of those arrangements. In order to provide a basis for such arrangements this study investigated and explored…

The purpose of this study is to investigate prospective physics teachers' knowledge of and attitude towards radiation and radioactivity. Participants of this study are 56 prospective physics teachers. A questionnaire related with the knowledge about radiation and radiation fear was conducted. The results of this study showed that most of the…

Sunscreens have different levels of protection, measured most commonly with the sun protection factor (SPF). Students initially believed higher SPF factors mean greater sun protection and learned through this activity that higher SPF does not mean greater protection. Students analyzed the amount of ultraviolet radiation (UVR) protection and…

The science education literature shows that students have difficulty understanding what causes the seasons. Incorrect explanations are often due to a lack of knowledge about the physical mechanisms underlying this phenomenon. To address this, we present a module in which the students engage in quantitative measurements with a photovoltaic panel to…

This article presents the results of a trend study investigating what students associate with the term radiation and what ideas they have about this topic. The first part of the interview study was conducted in June 2010 and its results were reported in a previously published article (Neumann & Hopf, 2012). Two years later (June 2012, 15…

This research compared three clinical preparedness domains, communication ability, social comfort, and clinical confidence, between US-born and non-US born radiation sciences students. The aim of the study was to determine if there were perceived differences in clinical preparedness between them. Student's place of birth was found to be an…

The importance of nonvisible wavelengths for the study of astronomy suggests that student understanding of nonvisible light is an important consideration in astronomy classrooms. Questionnaires, interviews, and panel discussions were used to investigate 6-12 student and teacher conceptions of ultraviolet (UV) and infrared (IR). Alternative…

The school day makes up a major part of a child's everyday life. The time children spend outside of the classroom, including recess, lunch, physical education classes, field trips, and after-school activities, can result in a significant amount of sun exposure, especially if it occurs during the hours of peak sun intensity from 10 a.m. to 4 p.m.…

This project included three separate studies undertaken to determine the effectiveness of television instruction as a method of effectively delivering information about solar energy systems to present and future workers in related industries, and as a method of delivery for adult continuing education instruction. All three studies used a series of…

This manual contains Progress Checks and Tests for use in a Solar Heating Systems curriculum (see note). It contains master copies of all Progress Checks and Unit Tests accompanying the curriculum, organized by unit. (The master copies are to be duplicated by each school so that adequate copies are available for student use in a self-paced student…

Discusses health concerns associated with the use of video display terminals (VDT) and provides guidelines to enhance the performance of VDT users. Health issues addressed include radiation, musculoskeletal, psychological, and visual concerns. Guidelines for a well-designed VDT environment are also presented, including hardware considerations,…

A survey of 161 students who graduated from Mississippi County Community College (MCCC) during the years 1977-79 with an associate of applied science degree was conducted to determine the occupational success of the graduates, their perceptions of the strengths and weaknesses of MCCC, and suggestions for improvement. The survey instrument…
