Bioinformatics Education in High School: Implications for Promoting Science,Technology, Engineering,and Mathematics Careers

We investigated the effects of our Bio-ITEST teacher professional development model and bioinformatics curricula on cognitive traits (awareness, engagement, self-efficacy, and relevance) in high school teachers and students that are known to accompany a developing interest in science, technology, engineering, and mathematics (STEM) careers. The program included best practices in adult education and diverse resources to empower teachers to integrate STEM career information into their classrooms. The introductory unit, Using Bioinformatics: Genetic Testing, uses bioinformatics to teach basic concepts in genetics and molecular biology, and the advanced unit, Using Bioinformatics: Genetic Research, utilizes bioinformatics to study evolution and support student research with DNA barcoding. Pre–post surveys demonstrated significant growth (n = 24) among teachers in their preparation to teach the curricula and infuse career awareness into their classes, and these gains were sustained through the end of the academic year. Introductory unit students (n = 289) showed significant gains in awareness, relevance, and self-efficacy. While these students did not show significant gains in engagement, advanced unit students (n = 41) showed gains in all four cognitive areas. Lessons learned during Bio-ITEST are explored in the context of recommendations for other programs that wish to increase student interest in STEM careers.     

Efficacy of the TELL language and literacy curriculum for preschoolers with developmental speech and/or language impairment

The purpose of this investigation was to examine the efficacy of a new preschool oral language and early literacy curriculum package (Teaching Early Literacy and Language [TELL]) for children with developmental speech and/or language impairment (DSLI) either as a primary (e.g., specific to speech and/or language) or secondary impairment (e.g., developmental delay that includes DSLI). Participants included 118 children (30 females, 88 males, M age = 53.58 months) with DLSI and their 29 preschool teachers. The design was a randomized controlled trial (RCT) with assignment to experimental versus contrast conditions at the classroom level. Teachers in TELL classes received formal training, in-class support, and mentoring to implement the curriculum. Dependent measures for the children included scores on the Clinical Evaluation of Language Fundamentals-Preschool 2nd edition (CELF-P2), the Phonological Awareness Literacy Screening for Preschool (PALS-PreK), the Renfrew Bus Story (BUS), and a receptive and expressive vocabulary measure developed for this investigation (VOCAB). Results indicated that when compared to the contrast group, children in the TELL condition demonstrated greater gains on the phonological awareness subtest of the CELF-P2, the sentence length score of the BUS, the letter sounds, beginning sound awareness, and rhyme awareness subtests of the PALS-PreK, and VOCAB. Results suggest that the TELL curriculum package has promise for promoting gains in early literacy and oral language skills in preschool children with DLSI.     

The Concept of Information Overload: A Review of Literature from Organization Science, Accounting, Marketing, MIS, and Related Disciplines

Based on literature from the domains of organization science, marketing, accounting, and management information systems, this review article examines the theoretical basis of the information overload discourse and presents an overview of the main definitions, situations, causes, effects, and countermeasures. It analyzes the contributions from the last 30 years to consolidate the existing research in a conceptual framework and to identify future research directions.     

Preschool Children's Evolving Conceptions of Badness: A Longitudinal Study

The purpose of this research was to investigate longitudinally preschool children's conceptions of badness. Forty children from the Block and Block study of personality and cognitive development were interviewed at ages 3, 4, and 5 years. When asked to generate things children do that are “bad”, preschoolers predominately generated events entailing negative consequences to others, that is, moral transgressions. They also mentioned events pertaining to conventional violations, emotional expressions, prudential situations, and punishments, but these were comparatively rare. The moral transgressions generated involved physical harm, property violations, and inter- personal trust violations. Physical harm was referred to significantly more often than the latter two moral categories. These findings were stable across the preschool years.     

Reading Aloud with Infants: The Controversy, the Myth, and a Case Study

Reading aloud to infants continues to be the focus of controversy between educators, researchers, and health care professionals. This article will provide insight into what research says about reading aloud to infants as well as the results of a case study of a six-month-old infant who has been read aloud to in utero to the present time. The results of this case study confirm that parents and caregivers reading aloud to infants is necessary in developing literacy skills that are paramount to book awareness, print awareness, vocabulary development, fluency, and comprehension, all of which are stepping stones to learning to read and write.     

Food Safety Education Using Music Parodies

ABSTRACT:  Musical parodies of contemporary songs with their lyrics altered to address current food safety issues were incorporated into a variety of food safety educational programs and the effectiveness of the music was evaluated by semiquantitative and qualitative measures. Audiences receiving the music-enriched curricula included school foodservice supervisors, school foodservice managers, culinary arts instructors, culinary arts students, Family and Consumer Sciences teachers, and youth aged 8 to 12 y and studies were conducted in South Carolina, North Carolina, and Delaware. Among school foodservice supervisors, school foodservice managers, and culinary arts students, most participants were able to recall the main points of each song that was introduced in the curriculum. The culinary arts students were less likely to recall the main points of each song than were the other 2 groups, possibly because of the lack of prior knowledge of food safety practices as well as a lack of preference for the style of songs used. Family and Consumer Sciences teachers were enthusiastic about the use of the music but also identified potential barriers to the successful use of the music, due to the potential lack of appropriate audiovisual equipment, a lack of skills in using such equipment, and time constraints for the use of music in curricula due to the strong emphasis on end of year testing. Participants in the summer youth groups demonstrated significant increases between pre- and posttest examinations of safe food handling behaviors and most were able to quote lines or phrases from the songs.
