Building Multicultural Awareness in University Students Using Synchronous Technology

To explore the potential for building multicultural awareness in university students using synchronous technology, faculty members from an American regional state university and a Chinese regional university collaborated to find appropriate ways to integrate synchronous technology (e.g., Adobe Connect) into a teacher education program in the American university and in an English as a Foreign Language (EFL) program in China. The paper reports the collaborative efforts during the spring 2016 semester using Adobe Connect to enrich student learning at both sites. This report includes the project overview, project implementation, its evaluation framework, and initial findings.     

Online teaching competencies in observational rubrics: what are institutions evaluating?

Evaluation of online instructors is a developing field of research. Institutions have made great progress in recent years to refine their efforts to evaluate online teaching in order to improve online teaching. Some institutions, however, still struggle to evaluate online instructors who did not design the course they are teaching. The purpose of this study was to identify some of the most important observable teaching behaviors identified in evaluation rubrics and how these compare to established online teaching competencies. Findings indicate that there is a growing consensus of what are the most important, observable teaching behaviors, and that this can help improve existing models of online teaching competencies.     

The adoption of student-centered teaching materials as a professional development experience for college faculty

Efforts to promote the use of student-centered learning environments in STEM education have been tempered by a lack of professional development strategies that help faculty overcome common barriers to reform. This study investigated the impact that adopting a suite of student-centered teaching materials had on the teaching practices and beliefs of eight geoscience faculty at a variety of US institutions. Each instructor adopted 18 class lessons that were developed as part of the InTeGrate (Interdisciplinary Teaching about the Earth for a Sustainable Future) project into a semester-long course. The Teaching Practices Inventory (TPI) and Reformed Teaching Observation Protocol (RTOP) were used to collect data on teaching practices whereas instructor beliefs were captured with the Teacher Beliefs Interview (TBI). Data were collected over three semesters, a control semester using traditional materials, a pilot semester using the new materials, and a final treatment semester. While the TPI survey showed no self-reported changes in the practices, RTOP observations recorded the incorporation of more student-centered teaching practices. TBI results confirm that most of the instructors also made at least moderate shifts toward more student-centered beliefs about teaching and learning. These findings demonstrate that the adoption of well-crafted, student-centered instructional materials can have a positive impact on both the teaching practices and beliefs of college faculty.     

The structure of subject matter content and its instructional design implications

This paper discusses the analysis of subject matter structure for purposes of designing instruction. The underlying assumption is that subject matter structures provide an important basis for deciding how to sequence and synthesize the modules of a subject matter area. Four types of fundamental structures are briefly described and illustrated: the learning hierarchy, the procedural hierarchy, the taxonomy, and the model. Then a theoretical framework is presented for classifying types of subject mater content — both modules and structures. Finally, some implications of these content classifications are discussed. The classification of modules is hypothesized to be valuable for prescribing strategies for the presentation of single modules, and the classification of structures is hypothesized to be valuable for prescribing strategies for selecting, sequencing, synthesizing, and summarizing related modules. The need to take into account more than one kind of structure in the process of instructional design is emphasized.     

Effects of induced orthographic and semantic knowledge on subsequent learning: a test of the partial knowledge hypothesis

Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, also known as “frontier words” (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar. However, studies investigating this question have produced mixed findings, and individual differences in baseline knowledge have complicated results both within and across studies. We present two studies that took a different approach, controlling both familiarity and the nature of the familiarizing episode. We controlled familiarity with novel words through pre-exposure (“pre-familiarization”) in isolation, to induce form-based familiarity, or in sentences that provided few clues to meaning, to induce partial semantic knowledge. The number of pre-exposures varied (0, 1, or 4). After the pre-familiarization phase, we presented the words in several highly informative sentences to support meaning acquisition. Participants included both adults and typically developing children, ages 9–12. Participants’ self-rated familiarity with target words, and their knowledge of the words’ meanings and orthography were each measured at baseline, immediately after learning, and 1 week later. Orthographic and semantic word learning showed contrasting effects of pre-familiarization. For orthographic learning, it was the number, rather than the type, of pre-familiarizations that mattered most. By contrast, the number of pre-familiarizations had little impact on word semantic learning; further, pre-familiarization in low-constraint sentences did not consistently boost subsequent learning. These findings suggest that familiarity with a word prior to instruction does not necessarily improve word-learning outcomes, and they highlight the importance of repeated exposures to high quality contexts for robust word learning.     

Associations between Phenylalanine-to-Tyrosine Ratios and Performance on Tests of Neuropsychological Function in Adolescents Treated Early and Continuously for Phenylketonuria

Phenylketonuria (PKU) is a genetic disorder characterized by hyperphenylalaninemia. Treatment involves dietary phenylalanine restriction to prevent mental retardation. Because phenylalanine is involved in tyrosine synthesis and tyrosine is a catecholamine precursor, low tyrosine may lead to brain dopamine deficiencies. Because dopamine is involved in the modulation of prefrontally orchestrated executive functions, deficiencies may lead to executive impairments. Despite treatment, impairments in executive cognitive functions have been reported in young children with PKU. Outcome beyond middle childhood has not been extensively investigated. In this study, PKU-affected adolescents (N = 18) with normal-range IQ scores completed neuropsychological tests, and their performance was compared with unaffected peers (N = 16) and chronically ill controls (N = 17). Results demonstrated that the overall performance of the PKU group did not differ from that of the other two groups, but that performance of the PKU proband was associated with phenylalanine and tyrosine levels, and most strongly with phenylalanine-to-tyrosine ratios at several points in development. These findings provide a preliminary test of the dopamine hypothesis of PKU as it applies to adolescents and young adults.     

A model of MBA student performance

A number of regression studies have attempted to predict success in an MBA program. The current study extends the work of previous investigations by proposing a model that incorporates a number of terms which represent interaction of undergraduate grade point average with undergraduate institution and undergraduate major. The resulting model has a significantly largerR ² value then previously reported studies. The largeR ² value is attributed to a more complete model and a careful scrutinizing of the data employed in model construction.     

Transsituational negative contrast

Rats were shifted from 32% sucrose solution in one apparatus to a 4% sucrose solution in a different apparatus, and the performance of these animals was compared to rats that received the 4% solution in both situations. Transsituational negative contrast effects were found in both consummatory and instrumental measures of behavior and, in addition, these contrast effects were found to have some elements in common with both successive and simultaneous contrast effects, but were identical to neither.
