A bacterium was isolated by elective culture with p-hydroxybenzoate as substrate and nitrate as electron acceptor. It grew either aerobically or anaerobically, by nitrate respiration, on a range of aromatic compounds. The organism was identified as a pseudomonad and was given the trivial name Pseudomonas PN-1. Benzoate and p-hydroxybenzoate were metabolized aerobically via protocatechuate, followed by meta cleavage catalyzed by protocatechuic acid-4,5-oxygenase, to yield a-hydroxy-'y-carboxymuconic semialdehyde. Pseudomonas PN-1 grew rapidly on p-hydroxy-430
Purpose
College students need more support learning to effectively search for and evaluate online information. Without such skills, students are vulnerable to mis- and disinformation that may appear in their search results, Web browsing and social media feeds. This study investigated four short instructional modules four short instructional modules that were developed to be delivered asynchronously to teach effective approaches to online search and evaluation.
Design/methodology/approach
This exploratory study analyzed pre- and post-tests that students in two journalism courses completed before and after the modules. A total of 29 students completed written versions of the pre- and post-tests and 8 students participated in interviews in which they thought aloud while completing the pre- and post-tests. Written and oral responses were analyzed to understand students’ search and evaluation strategies and how, if at all, these shifted from pre- to post-test.
Findings
From pre- to post-test, students showed evidence of using strategies that were introduced in the modules to search for and evaluate online content. On the post-test, more students engaged in lateral reading to evaluate unfamiliar websites, used search operators and tools and more critically evaluated elements of the search engine results page.
Originality/value
This study provides initial, positive evidence for the efficacy of embedding short, asynchronous modules in college courses to improve students’ approaches to online searches and evaluations. College students need such support and modules like the ones investigated in this study may be one way to provide it.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
