Supporting the Essential Elements with CD-ROM Storybooks

CD-ROM storybooks can support the development of the five essential elements of reading instruction identified by The National Reading Panel: phonemic awareness, phonics, fluency, vocabulary, and comprehension. Specific features inherent in these texts, audio pronunciation of text, embedded vocabulary definitions and animated graphics can be used to support readers\u27 development of various reading skills. In addition, the International Society for Technology in Education states that computer technology should be used with young children to build their technological skill and comfort level. The use of CD-ROM storybooks for instruction in the five essential elements is an effective means of incorporating technology in a meaningful way

High-frequency performance of Schottky source/drain silicon pMOS devices

A radio-frequency performance of 85-nm gate-length p-type Schottky barrier (SB) with PtSi source/drain materials is investigated. The impact of silicidation annealing temperature on the high-frequency behavior of SB MOSFETs is analyzed using an extrinsic small-signal equivalent circuit. It is demonstrated that the current drive and the gate transconductance strongly depend on the silicidation anneal temperature, whereas the unity-gain cutoff frequency of the measured devices remains nearly unchanged

P2P: Assessing a Peer Evaluation Strategy

The purpose of this study was to determine the effectiveness of peer evaluation in a performance-based, Web-enhanced undergraduate instructional technology course. The results of a survey administered at the end of three semesters indicated that learners believe the peer evaluation process helped them improve the quality of their own work, both as a result of being a peer evaluator themselves and from the quality of the feedback received from their classmate-evaluators. Higher quality final projects with fewer mistakes corroborated the students’ assessment. These findings provide valuable information for instructors who are currently utilizing or considering the implementation of a peer evaluation process as a part of their instructional strategy. The results of this study indicate that including peer evaluation in the final project enhanced student performance. Significant technology integration was used to facilitate the projects

Letter from the Editor

Our inspiration to conduct research can come from anywhere. For some, it might be an interesting idea from a lecture, or a unique detail from a research article. For others, it could be an observation of the world around us, whether it is of the behavior of people or the inner workings of nature. Each day we are all struck by this inspiration, as our surroundings are rich with the potential to draw out our latent curiosity. One of the rewarding qualities of research is when we become curious enough to pursue this inspiration, wherever it might take us. The OURJ exists to celebrate this curiosity, as each of these works reflect their author's passion to follow their questions to a logical end

Laser frequency locking by direct measurement of detuning

We present a new method of laser frequency locking in which the feedback signal is directly proportional to the detuning from an atomic transition, even at detunings many times the natural linewidth of the transition. Our method is a form of sub-Doppler polarization spectroscopy, based on measuring two Stokes parameters ($I_2$ and $I_3$) of light transmitted through a vapor cell. This extends the linear capture range of the lock loop by up to an order of magnitude and provides equivalent or improved frequency discrimination as other commonly used locking techniques.Comment: 4 pages, 4 figures Revte

Genotyping-by-sequencing resolves relationships in Polygonaceae tribe Eriogoneae

The resolution of cryptic diversity is essential for understanding the evolutionary diversification of lineages and establishing conservation priorities. We examine relationships in Eriogoneae (Polygonaceae), a diverse lineage in western North America. We ask whether Eriogonum umbellatum, a morphologically and ecologically diverse species, is monophyletic and whether its varieties represent evolutionary lineages. We use genotyping-by-sequencing to assemble a SNP dataset for 51 species in the genera Chorizanthe, Eriogonum and Sidotheca. We report a hierarchical phylogenetic analysis using maximum likelihood to estimate the evolutionary history of Eriogoneae. We illustrate admixture components for 21 populations of E. umbellatum, representing four varieties, and test for lineage structure using TreeMix. We identify strongly supported clades within Eriogoneae. Many relationships in the Eucycla + Oregonium and Latifolia clades are supported, while most relationships within the Eriogonum subg. Oligogonum clade and a clade with most Chorizanthe remain unresolved. Eriogonum congdonii resolves within the main E. umbellatum clade, while populations of three varieties of E. umbellatum are closely related to E. ursinum and are associated with serpentine soils. ADmixture and TreeMix analyses suggest E. umbellatum varieties represent evolutionary lineages. These results from SNP data are largely consistent with previous phylogenetic studies of Eriogoneae based on sequence variation. Structure within Oligogonum suggests consistent environmental association and radiation after initial colonization of serpentine. Morphology is unreliable for the infraspecific taxonomy of E. umbellatum. Additional molecular studies are needed to resolve the evolutionary relationships and ecological diversification within this species, in Oligogonum, and in Eriogoneae. © 2021 The Authors.
