Improving the Background Knowledge of Non-traditional Students

Three intervention methods to assist non-traditional college students in evaluating and improving their chemical and mathematical backgrounds were developed and implemented over three successive years. The goal was to improve students' self-confidence and success in the course. The first method was a one-day optional symposium featuring a variety of tutorial sessions. In the second, a pre-test helped students determine potential deficits in requisite knowledge, and topical workshops were made available outside of class time. The third method used the same assessment pre-test combined with instructional videos on selected topics drawn from the pre-test. The three approaches were compared in a formative sense with respect to 1) student identification of areas of potential weakness, 2) accessibility of each method to the non-traditional student population. The success of the third method at improving student course performance was also examined.     

Characterizing Learning Environments Capable of Nurturing Generic Capabilities in Higher Education

There has been wide recognition that today’s graduates need the type of generic capabilities necessary for lifelong learning. However, the mechanism by which universities can develop these generic skills is not clearly established. This study aimed to investigate the mechanism for their development. Structural equation modeling (SEM) was used to test a hypothesized model of capability development through a suitable learning environment with 1756 undergraduates at a university in Hong Kong. To triangulate against this model and more fully characterize the learning environment, focus group interviews were held with five to six students from three programs with good records of capability development. Analysis of the interview data resulted in a set of categories, describing a learning environment, which were consistent with the SEM model. The learning environment which seemed conducive to capability development aimed for understanding of key concepts through a variety of assessment methods and active engagement in learning activities. Teacher–student relationships were developed through interaction, feedback and assistance. The promotion of peer–student relationships led to a high degree of collaborative learning.     

Review of Single Subject Research Examining the Effectiveness of Interventions for At‐Risk English Learners

We review published single subject design (SSD) studies that examine the effects of interventions for English learners at‐risk or with learning disabilities. Results of our literature search yielded 10 studies, five in reading, one in reading and behavior, and four in mathematics that met our inclusion criteria. Seven studies targeted Spanish‐speaking English learners, and three studies included students who spoke other languages than English and/or English only students. Two studies in mathematics included native language instruction. Six studies included English learners in second grade and above, and one study included high school students. We were able to calculate effect sizes (Hedges g) for eight of the 10 studies. Findings indicated a significant effect of the intervention for 12 of the 18 dependent variables measured. SSD methodology has the potential to help researchers and practitioners better understand what interventions work for English learners, and under what circumstances.     

Investigating the Psychometric Properties of the ACEI Global Guidelines Assessment,Third Edition (GGA) in Nine Countries

The Third Edition of the ACEI Global Guidelines Assessment (GGA) was evaluated for its effectiveness as an international assessment tool for use by early childhood educators to develop, assess, and improve program quality worldwide. This expanded study was conducted in nine countries [People’s Republic of China (2 sites), Guatemala, India, Italy, Mexico (2 sites), Peru (2 sites), Taiwan, Thailand, United States] to continue the investigation of the psychometric properties of the GGA. A total of 346 programs and 678 early care and education professionals participated in this study. Results primarily confirmed the findings of the previous study, (Hardin et al. in Early Child Educ J 41(2): 91–101, 2013), indicating that the GGA showed strong to moderate internal consistency and interrater reliability for subscale ratings across this larger number of countries and programs. The congruence of item ratings and written evidence to support ratings was acceptable, although some programs had lower participation in providing evidence. To test concurrent validity of ratings, external raters also evaluated a subset of programs (n = 44 from Peru and United States) on both the GGA and the Early Childhood Environment Rating Scale-Revised that showed moderate positive correlations. Patterns of program practices were also identified within and across the participating sites and countries. Results suggest that the GGA can be used as an onsite evaluation method that can help stakeholder participants (teachers and administrators) increase their awareness of program quality standards and serve as an assessment method for their own programs. In particular, the results suggest the GGA is a reliable and useful instrument that can be used effectively by early childhood stakeholders for assessing and improving program quality worldwide (Bergen and Hardin in Child Educ 91(4): 259–264, 2015).     

Assessing Knowledge and Attitudes of U.S. Healthcare Providers about Benefits and Risks of Consuming Seafood

An online needs assessment survey of healthcare providers was developed and implemented to determine knowledge and attitudes about the benefits and risks of consuming seafood along with how this might impact patient/clientele counseling. Only 6 of the 45 knowledge items queried (13%) met the 80% subject mastery or proficiency with a total knowledge score of 56 ± 18%. Based on this survey, it was found that healthcare providers were less than proficient regarding all knowledge areas for seafood. Understanding of seafood safety and contaminants was low. In addition, while the majority (76%) of healthcare respondents knew the correct recommendation for seafood meals per week, they failed to identify the groups that were targeted by the Food and Drug Administration/Environmental Protection Agency (FDA/EPA) advisory about seafood and mercury and therefore could be providing inaccurate information. Attitudinal responses for 18 items resulted in an overall average score of 3.28 ± 0.47 meaning slightly agree (based on a 5‐point Likert scale strongly disagree—strongly agree). While trends showed that it was important to the respondents to provide accurate information (3.78 ± 1.06) about seafood to their patients, they felt more comfortable recommending that their patients follow government advice (3.52 ± 0.91) about both seafood safety and which seafood to eat over other sources. Combined with a low knowledge base, attitudinal responses indicate that there could be a barrier to both outreach education to these healthcare providers and to their patient counseling regarding seafood consumption. Results also showed that a combination of online, science‐based, easy to access information with the capability to provide brochure‐formatted information would appear to be the best way to communicate seafood safety, nutrition, and health information.     

Language‐Switching Costs in Bilingual Mathematics Learning

Behavioral studies on bilingual learning have revealed cognitive costs (lower accuracy and/or higher processing time) when the language of application differs from the language of learning. The aim of this functional magnetic resonance imaging (fMRI) study was to provide insights into the cognitive underpinnings of these costs (so‐called language‐switching costs) in mathematics. Twenty‐nine bilingual adults underwent a 4‐day arithmetic training in one language, followed by an fMRI test session in which they had to solve the trained problems in both languages. Language‐switching costs were accompanied by increased activation in areas associated with magnitude processing (intraparietal sulcus), visuo‐spatial imagery (precuneus), numerical stimulus recognition (fusiform gyrus) and executive functions (frontal areas). These findings suggest that language‐switching costs in arithmetic are due to additional numerical information processing. Bilingual education programs need to take these findings into account to reduce language‐switching costs in order to fully exploit the potential of bilingual learning.     

Upper Secondary Students’ Understanding of the Use of Multiple Models in Biology Textbooks—The Importance of Conceptual Variation and Incommensurability

In this study we investigate students’ ability to discern conceptual variation and the use of multiple models in genetics when reading content-specific excerpts from biology textbooks. Using the history and philosophy of science as our reference, we were able to develop a research instrument allowing students themselves to investigate the occurrence of multiple models and conceptual variation in Swedish upper secondary textbooks. Two excerpts using different models of gene function were selected from authentic textbooks. Students were given the same questionnaire-instrument after reading the two texts, and the results were compared. In this way the students themselves made a classification of the texts which could then be compared with the researchers’ classification of the texts. Forty-one upper secondary students aged 18–19 participated in the study. Nine of the students also participated in semi-structured interviews. Students recognized the existence of multiple models in a general way, but had difficulty discerning the different models and the conceptual variation that occurs between them in the texts. Further they did not recognize the occurrence of incommensurability between multiple models. Students had difficulty in transforming their general knowledge of multiple models into an understanding of content specific models of gene function in the textbooks. These findings may have implications for students’ understanding of conceptual knowledge because research has established textbooks as one of the most influential aspects in the planning and execution of biology lessons, and teachers commonly assign reading passages to their students without further explanation.     

Development of an Objective Measure of Rhythmic Motor Response

Abstract

This study was undertaken to develop a test that would objectively measure the rhythmic element in dance, and one that could be used by teachers of dance. The resulting Test of Rhythmic Motor Response was administered to 92 college women enrolled in dance classes. Test reliability coefficients ranged from .90 to .91; validity coefficients with teachers' ratings, .49 to .51. An investigation of the relationship between this test and the rhythm imagery section of the Gordon Measures of Musical Perception yielded correlation coefficients ranging from .52 to .69. These findings are all statistically significant at the .01 level. The Test of Rhythmic Motor Response appears to have a substantial relationship with the rhythmic element in dance.
