In this article, we ‘think with’ the theoretical concepts of flow, rupture, layering, and sampling to affectively attune to ‘in-the-red frequencies’ flowing across/with-in a New York City primary classroom—that is, alternative sonic frequencies that trouble and refuse hegemonic literacy practices. These hip-hop concepts theorise affect in relation to Black intellectual frameworks for moving, feeling, and sounding. Such frameworks honour philosophical practices emerging from Black people's lived experiences—practices that, historically, have been perceptually coded out of legibility by white supremacist institutions. Ultimately, we argue that thinking with flow↔rupture↔layering↔sampling enables more equitable practices that push literacies ‘into the red,’ namely, by respecting multiple perspectives, histories, and truths; accounting for power, privilege, positioning, and complicity; and highlighting ‘otherwise’ social worlds not predicated on hegemonic whiteness, anti-blackness, and socio-political violence.  相似文献

Mathematical modeling is a high-leverage topic, critical for college and career readiness, participation in STEM education, and civic engagement. Mathematical modeling involves connecting real-world situations, phenomenon, and/or data with mathematical models, and in this way applies across various STEM disciplines, including mathematics, engineering, and science. Although research has begun to explore mathematical modeling instruction in the elementary grades, questions remain about how to assess student learning at the elementary level. We addressed this need by designing an assessment of mathematical modeling competencies for students in grades 3 through 5. Informed by international research, our assessment includes a hybrid structure to assess mathematical modeling competencies holistically (as students engage in the complete modeling process) and atomistically (as students engage in different components of the modeling process, including making sense of phenomena and real-world situations, setting up and operating on mathematical models, and interpreting results in relation to the real-world context). We conducted student interviews, followed by two rounds of pilot testing to inform item development and ensure acceptable psychometric properties. The final assessment included 13 items (9 multiple choice, 3 open-response, and 1 complete modeling task). We describe our assessment development process, and provide sample assessment items and detailed coding rubrics. We summarize quantitative analyses which established high reliability and low standard error for our assessment, supporting its use for grades 3 to 5. Implications of our framework and assessment for mathematical modeling instruction and future research on STEM learning are discussed.

The purpose of this study is to introduce a measure of standards-based mathematics teaching practices, the Mathematics Scan (M-Scan), and to examine its validity and score reliability. First, we define standards-based mathematics teaching practices based on eight dimensions that have emerged in recent conceptualizations by researchers and in the context of existing observational measures. Second, we present three sources of validity evidence: content review by experts, analysis of response processes of coders, and convergent and discriminant patterns with existing observational measures. Third, we provide evidence of inter-coder (or inter-rater) reliability through analyses of variance components and calculation of reliability coefficients, using the framework of generalizability theory. Results show the M-Scan holds promise as a useful tool in mathematics education research, measuring indicators of standards-based teaching practices unique to the subject of mathematics.  相似文献

Currently, there are few strengths‐based preschool rating scales that sample a wide array of behaviors believed to be essential for early academic success. The purpose of this study was to assess the factor structure of a new measure of early academic competence for at‐risk preschool populations. The Teacher Rating Scales of Early Academic Competence (TRS‐EAC) includes two broad scales (Early Academic Skills and Early Academic Enablers) and was completed by 60 teachers for 440 children enrolled in Head Start and public preschool classrooms. Evidence from two exploratory factor analyses supported a five‐factor solution for the Early Academic Skills Scale (Creative Thinking, Critical Thinking Skills, Numeracy, Early Literacy, and Comprehension) and a five‐factor solution for the Early Academic Enablers Scale (Approaches to Learning, Social and Emotional Competence, Fine Motor Skills, Gross Motor Skills, and Communication). TRS‐EAC scores also demonstrated good to excellent reliability and were related to children's performance on direct measures of early academic skills.  相似文献

This study reports on results from the Early Mathematics Beliefs and Confidence Survey, administered to 346 preschool teachers in a large public school system in the Midwest. Survey results depict a much more positive view of teachers’ beliefs and confidence in early math teaching than previously reported. Results also suggest that teacher confidence varies with specific types of math knowledge and teaching abilities, and assessing math learning is a specific area where teachers lack confidence. Examining confidence in their math abilities and in teaching early math, results indicate that teachers are more confident teaching math and remain confident in teaching even when confidence in their abilities is low. Implications of results for early math professional development are discussed.  相似文献

This synopsis centers on Eleanor Duckworth’s ideas about the relationship between education and intellectual development. Specifically, Duckworth described the essence of intellectual development as the “having of wonderful ideas” and the essence of pedagogy as the creation of occasions to “have wonderful ideas.” As opposed to accepting the persistent, pernicious educational belief that there is a single, best way to understand and a single, best way of explaining this understanding, Duckworth determined that all children can come to comparable, equally satisfactory, wonderful understandings when provided occasions to do so.  相似文献

The present experiments, using the latent inhibition (LI) paradigm, evaluated the effect of nonreinforced exposure to saccharin on the acquisition of an LiCl-induced saccharin aversion as measured by conditioned disgust reactions in the taste reactivity test and conditioned taste avoidance in a consumption test. When rats were preexposed to saccharin by bottle exposure (Experiments 1 and 3), LI was evidenced only by conditioned taste avoidance (bottle testing), but not by conditioned disgust reactions (intraoral [IO] testing). On the other hand, when rats were preexposed to saccharin by IO infusion (Experiments 2 and 3), LI was evidenced only by conditioned disgust reactions, but not by conditioned taste avoidance. Experiment 4 showed that LI of conditioned disgust reactions does not appear to be affected by a context shift from preexposure to testing phases. These results show that the expression of LI of both conditioned taste avoidance and conditioned disgust reactions depends critically on a common method of flavor exposure during preexposure and testing.  相似文献

To inform public health recommendations for adolescent sleep, the amounts of sleep associated with the highest levels of academic achievement and mental health were examined. The degree to which daily variability in sleep duration represents an underappreciated but functionally significant sleep behavior also was tested. A total of 421 adolescents (Mage = 15.03 years) with Mexican‐American backgrounds reported nightly sleep times for 2 weeks; approximately 80% repeated the same protocol 1 year later. Multilevel modeling indicated that the amount of sleep associated with the lowest levels of internalizing and externalizing symptoms was more than 1 hr greater than the amount associated with the highest levels of academic performance. Greater daily variability in sleep duration predicted greater symptomatology and mixed academic outcomes.  相似文献
