Educational Technology

The Oceans of Data project has made an attempt to define and confront what is “hard” for students and teachers who attempt to use large, online professional data sets. We feel passionately that it’s important for us to do this to prepare today’s students for tomorrow’s world.

This article describes an online climate change curriculum that incorporates dynamic computer models that enable students to visualize the complex interactions related to climate change science. Students learn how adjusting variables in a dynamic model affects the entire system.

Due to the rapid advancements of information and communication technologies (ICTs), educational researchers argue that multimodal and new literacies should become common practices in schools. As new ICTs emerge and evolve, students need the new literacies skills and practices to successfully participate fully in the civic life of a global community. Are teachers prepared to integrate ICTs in the classroom to develop students’ new literacies skills? The purpose of this study is to suggest a new literacies framework that guides ICTs integration and supports scientific inquiry, as well as investigate middle school teachers’ confidence to practice new literacies in science classrooms. The study adopted mixed-methodology design, surveyed 32 middle school science teachers’ ICTs and new literacies skills, and randomly observed 15 teachers’ new literacies practices in the classrooms. The results revealed that even though teachers have high confidence in using ICTs, the meaningful technology integration and new literacies practices were scarcely observed in their classroom practices.

A four-year research project funded by NSF examines the efficacy of an approach to high school geometry that utilizes dynamic geometry (DG) software and supporting instructional materials to supplement ordinary instructional practices. It compares effects of that intervention (the DG approach) with standard instruction that does not make use of computer tools. This paper reports a study conducted during the second year of the project. Student learning is assessed by a geometry test and other tests. Data for answering the research questions of the study are analyzed mainly by appropriate HLM methods. The analysis on the geometry test data is discussed in detail. The experimental group significantly outperformed the control group in geometry performance.

Many of us learned about dominant and recessive genes in a humdrum high school biology class. Some of us may still recognize the terms and symbols twenty or thirty years later—are your eyes bb or Bb? But, as it turns out, a very small number of traits in humans and other animals, plants, amoeba … you name it … involve the dominance mechanism of a single gene with just two alleles. (An allele is a variation of a gene, like the B or b in the above example.) The more biologists discover about the mechanisms of inheritance, the fewer traits we can point to that involve only one gene or can be illustrated using a simple Punnett square. In fact, biologists are compiling information about our genes at an astounding rate. As the process of sequencing DNA improves, the science of biology is dramatically changing.

This chapter concludes The role of criticism in understanding problem solving. In it, the overall message of the book—that criticism and critical theories can serve to aid critical reading and synthesis of the educational technology research literature—is summarized. One of the strengths of the educational technology field is its interdisciplinarity. As students enter the field from many different academic disciplines, they should be encouraged to apply not just the content of their former disciplines but also the strategies of and frameworks for thinking about problems.

The concept of criticism as a tool for research, although well established in other educational research traditions, is not well established in the domain of Educational Technology. This book changes all that by substantiating criticism as a way to step back and critically evaluate an educational intervention within educational technology. Doing so provides an valuable approach for researchers in terms of guiding meta analyses and theoretical studies, preventing the proverbial "spinning of the wheels" that often happens in educational research.
