Pedagogy for partisanship: research training for Black graduate students in the Black intellectual tradition

Current and former students of two professors in a southern research university and a community educator, all participants in an African-centered research collaborative/apprenticeship, describe what and how we study together and our struggle to use our knowledge and research in service to our community. We uplift the works of key Pan-African/Black/Africana Studies/Nile Valley scholars to illustrate the African epistemic foundation of our collaborative/apprenticeship. We describe how we utilized the methodology of narrative inquiry to explore our experiences as participants in the HeKA (Heritage Knowledge in Action) research collaborative and how HeKA has provided ways of knowing and being centered in our culture and heritage. We present our findings, which include some of the dilemmas of Black doctoral students and emerging scholars engaged in HeKA and how this collaborative/apprenticeship serves as an emancipatory praxis to enable the next generation to realize their goals of partisan research and pedagogy in higher education.     

Exploring the relationship between certification sources,experience levels,and classroom management orientations of classroom teachers

Teachers continue to report that classroom management is one of their greatest challenges in the classroom. Classroom management involves teacher's efforts to oversee classroom activities such as learning, social interaction, and student behavior. In this study, we examined the relationship between sources of teachers’ certification (traditional or alternative), teachers’ experience levels (experienced or novice), and teachers’ classroom management orientations (interventionist, non-interventionist, or interactionalist). We discovered that neither source of certification nor experience level alone impacts a teachers’ classroom management orientation. However, teachers with traditional certification and many years of experience exert significantly less control over classroom activities and students’ behaviors than do their colleagues with other educational and experimental backgrounds. Potential causes and ramifications of these findings are discussed.     

Nonword recall and phonemic discrimination in four‐ to six‐year‐old children

Previous research has established that the degree of ‘wordlikeness’ of nonwords affects young children's nonword repetition performance. Experiment 1 examined the possibility that output processes are responsible for the wordlikeness effect by using a probed recall procedure. Wordlikeness was defined in terms of phonological neighbourhood density, although this measure was found to be related to the traditional measure of wordlikeness involving adult ratings. A significant effect of number of phonological neighbours/wordlikeness was observed in favour of nonwords with many neighbours. In Experiments 2 and 3 the wordlikeness effect was qualified by a significant interaction with nonword repetition ability. Children with poorer repetition ability were affected by number of neighbours/wordlikeness, while children with better repetition ability were not. Children with poorer repetition ability were significantly poorer than the better repeaters with nonwords with few neighbours. The results were interpreted in terms of theories of phonological development that suggest progressive segmentation of lexical representations. In Experiment 4 the relationship of children's nonword repetition ability to phonemic discrimination ability was investigated. The results demonstrated that children with better nonword repetition ability had superior phonemic discrimination performance than children with poorer nonword repetition ability.     

The Impact of Science Fiction Film on Student Understanding of Science

Researchers who have investigated the public understanding of science have argued that fictional cinema and television has proven to be particularly effective at blurring the distinction between fact and fiction. The rationale for this study lies in the notion that to teach science effectively, educators need to understand how popular culture influences their students’ perception and understanding of science. Using naturalistic research methods in a diverse middle school we found that students who watched a popular science fiction film, The Core, had a number of misunderstandings of earth science concepts when compared to students who did not watch the movie. We found that a single viewing of a science fiction film can negatively impact student ideas regarding scientific phenomena. Specifically, we found that the film leveraged the scientific authority of the main character, coupled with scientifically correct explanations of some basic earth science, to create a series of plausible, albeit unscientific, ideas that made sense to students.     

Recasts Used with Preschoolers Learning English as their Second Language

This study examined linguistic recasts provided by 16 early childhood educators to preschool children learning English as a second language (EL2). Recasts are semantic and syntactic revisions of children’s utterances. The educator–child interactions were filmed during book reading and play dough activities with small groups of four children, one of whom was EL2. The EL2 children were rated by their educators as having less well-developed expressive language skills than their unilingual peers. However, despite this finding, educators provided similar rates of recasts to both groups of children. Eight EL2 children with the lowest expressive language skills demonstrated fewer uptakes of their educator’s recasts in comparison to EL2 children with higher expressive language skills. The implications of this study include increasing the rate of recasts and reducing their complexity to provide language-learning opportunities for all preschool children, especially for those learning English as a second language.     

Supplemental reading strategy instruction for adolescents: A randomized trial and follow-up study

In this study, the authors examine the impact of a yearlong supplemental reading course involving daily instruction in the learning strategies curriculum on lower achieving adolescent students' reading achievement and motivation. Using a multiple-cohort randomized treatment-control group design over 4 years, they compared achievement and motivation outcomes for 605 sixth-grade students who participated in the intervention with 530 students who did not participate and 593 ninth-grade students who participated in the intervention with 535 students who did not participate. Results indicated significant impacts of the intervention on reading achievement for ninth-grade students but not for sixth-grade students. Significant impacts on reading motivation were found for both sixth- and ninth-grade students. An exploratory follow-up study indicated potential benefits of a second year of intervention for sixth-grade students who are still low achieving after 1 year of intervention.     

The Effect of a Mentoring Model for Elementary Science Professional Development

This study describes an elementary science model of professional development through mentoring by university science education professors working with teachers at a private elementary school in a regional city in Queensland, Australia. A cross-cultural collaboration involving professors from the United States and Australia resulted in the socially constructed image of the science education mentor. While there is no generic model for elementary science mentoring, results of data collection reveal that (a) one-to-one mentoring has short-term implications for implementing constructivist science teaching practices; (b) successful mentoring models include facilitating the understanding of science content, exploring elementary science pedagogical content knowledge through modeling, and off-site professional development workshops; and (c) understanding and working from the predispositions of the teachers is an essential component of effective professional development.     

Mandatory criteria for the application of variability-based parameters of fluid responsiveness: a prospective study in different groups of ICU patients

Background and objective

Stroke volume variation (SVV) has high sensitivity and specificity in predicting fluid responsiveness. However, sinus rhythm (SR) and controlled mechanical ventilation (CV) are mandatory for their application. Several studies suggest a limited applicability of SVV in intensive care unit (ICU) patients. We hypothesized that the applicability of SVV might be different over time and within certain subgroups of ICU patients. Therefore, we analysed the prevalence of SR and CV in ICU patients during the first 24 h of PiCCO-monitoring (primary endpoint) and during the total ICU stay. We also investigated the applicability of SVV in the subgroups of patients with sepsis, cirrhosis, and acute pancreatitis.

Methods

The prevalence of SR and CV was documented immediately before 1241 thermodilution measurements in 88 patients.Results: In all measurements, SVV was applicable in about 24%. However, the applicability of SVV was time-dependent: the prevalence of both SR and CV was higher during the first 24 h compared to measurements thereafter (36.1% vs. 21.9%; P<0.001). Within different subgroups, the applicability during the first 24 h of monitoring ranged between 0% in acute pancreatitis, 25.5% in liver failure, and 48.9% in patients without pancreatitis, liver failure, pneumonia or sepsis.

Conclusions

The applicability of SVV in a predominantly medical ICU is only about 25%–35%. The prevalence of both mandatory criteria decreases over time during the ICU stay. Furthermore, the applicability is particularly low in patients with acute pancreatitis and liver failure.
