Data and data analysis are central to science and the complex world in which people live. Students need to practice working with data--addressed in the "Next Generation Science Standards" (NGSS Lead States 2013)--starting with small, self-collected data sets and moving on to larger, remotely collected data assemblages. Small data sets…

Many researchers have documented the difficulties for learners of different ages and preparations in understanding basic astronomical concepts. Traditional instructional strategies and communication media do not seem to be effective in producing meaningful understanding, or even induce misconceptions and misinterpretations. In line with recent…

This paper is an examination of a teacher professional development program in northeast Louisiana, that provided 30 teachers and their students with the technology, skills, and content knowledge to collect data and explore weather trends. Data were collected from both continuous monitoring weather stations and simple school-based weather stations…

Ocean acidification is one of the most serious environmental issues facing the planet (e.g., Doney 2006; Guinotte and Fabry 2009). It is caused by excess carbon dioxide (CO[subscript 2]) in the atmosphere. Human activities such as burning fossil fuels put CO[subscript 2] and other heat-trapping gases into the atmosphere, which causes the Earth's…

At the University of Vermont, an interdisciplinary faculty team developed an introductory watershed science field course. This course honed field skills and catalyzed communication across water-related disciplines without requiring specific prerequisites. Five faculty (geology, engineering, geography, natural resources) taught the four-credit…

An instructional unit incorporating some of the Global Learning and Observation to Benefit the Environment (GLOBE) hydrology protocols provides an excellent way to connect academic learning, scientific inquiry, multiple subjects, and the values required for concerned citizenship in a democracy. This article describes the GLOBE hydrology protocols…

Constructing model hot air balloons is an activity that captures the imaginations of students, enabling teachers to present required content to minds that are open to receive it. Additionally, there are few activities that lend themselves to integrating so much content across subject areas. In this article, the authors describe how they have…

Undergraduate students compared Next Generation Weather Radar (NEXRAD) estimates of storm total precipitation to measurements from a network of 20 rain gauges. Student researchers gained valuable experience in field data collection, global positioning systems (GPS), geographic information systems (GIS), Internet data access and downloading,…

Differentiating between time-series design and time-series analysis, examines design considerations and reanalyzes data previously reported by Mayer and Kozlow in this journal. The current analysis supports the analysis performed by Mayer and Kozlow but puts the results on a somewhat firmer statistical footing. (Author/JN)

Work on the development of the intensive time-series design was initiated because of the dissatisfaction with existing research designs. This dissatisfaction resulted from the paucity of data obtained from designs such as the pre-post and randomized posttest-only designs. All have the common characteristic of yielding data from only one or two…
