The Development of Teacher Knowledge in Support of Student Mathematical Inquiry

Abstract

Applying the Mathematical Knowledge for Teaching framework, we discuss the components of teacher knowledge that might be useful in supporting mathematical inquiry, and examine ways in which we strive to develop this knowledge within a middle grades mathematics program for undergraduate students who are prospective teachers. Using sample activities from multiple courses in the program, we offer general principles of instruction for supporting mathematical inquiry at all grade levels. We contend that an awareness and application of the multiple facets of mathematical knowledge for teaching can be critical to supporting mathematical inquiry across the K-16 spectrum.     

Component skills affecting elementary students’ informational text comprehension

This study was conducted to examine the factors that influence informational text comprehension and to determine how these vary for students with higher and lower component skills. The sample included 177 students in grades 3–5. Regression analyses were used to predict informational text comprehension with decoding efficiency, vocabulary knowledge, prior knowledge, and intrinsic motivation. This model, that also included age and grade as control variables, explained 62.5 % of the variance in informational text comprehension. Each component skill explained unique variance, and vocabulary knowledge accounted for the largest portion. Next, we examined whether the factors contributed differently to informational text comprehension for students with higher and lower component skills. Overall, the regressions were better predictors for students with higher than those with lower component skills. For students with lower component skills, motivation and vocabulary were consistent predictors, whereas vocabulary and decoding efficiency were consistent predictors for students with higher component skills. The findings indicate multiple factors are important for informational text comprehension, particularly vocabulary, and research should examine this topic for different types of readers.     

Impact of sustained professional development in STEM on outcome measures in a diverse urban district

Sustained professional development can support STEM (Science, Technology, Engineering, and Mathematics) reform. The authors describe a 3-year study of sustained professional development for 3 diverse urban schools across the salient factors of fidelity of implementation of project-based learning, development of professional learning communities, and student achievement. Qualitative and quantitative data were collected. The students who experienced the greatest fidelity of implementation exhibited the greatest gains (d = 1.41–2.03) on standardized test scores, while those with the lowest fidelity of implementation exhibited negative gains (d = –0.16 to –0.08). Qualitative data indicated teachers perceived there were multiple benefits from the implementation of project-based learning.     

Information literacy in science writing: how students find,identify, and use scientific literature

For undergraduate students to achieve science literacy, they must first develop information literacy skils. These skills align with Information Literacy Standards and include determining appropriate databases, distinguishing among resource types, and citing resources ethically. To effectively improve information literacy and science literacy, we must identify how students interact with authentic scientific texts. In this case study, we addressed this aim by embedding a science librarian into a science writing course, where students wrote a literature review on a research topic of their choice. Library instruction was further integrated through the use of an online guide and outside assistance. To evaluate the evolution of information literacy in our students and provide evidence of student practices, we used task-scaffolded writing assessments, a reflection, and surveys. We found that students improved their ability and confidence in finding research articles using discipline-specific databases as well as their ability to distinguish primary from secondary research articles. We also identified ways students improperly used and cited resources in their writing assignments. While our results reveal a better understanding of how students find and approach scientific research articles, additional research is needed to develop effective strategies to improve long-term information literacy in the sciences.     

Assessing and Predicting Small-Group Literacy Instruction in Early Childhood Classrooms

Research Findings: The present study assessed the extent to which early childhood educators utilized small-group literacy instruction and explored factors potentially associated with the use of this evidence-based practice. The classroom activities of 83 early childhood educators were observed in the fall and spring, and videos were coded to calculate time spent in small-group literacy instruction. Educators completed questionnaires indicating classroom adult:child ratios, literacy beliefs, and feelings of self-efficacy. Classroom Assessment Scoring System scores for classroom organization and instructional support measured the quality of classroom management and instructional interactions, respectively. On average, educators provided 11.4 min (SD = 10.6) of small-group literacy instruction a day. It is notable that many educators provided little or no small-group literacy instruction. Negative binomial regression analyses indicated that educators with better classroom management, higher quality instructional interactions, and lower adult:child ratios were more likely to use small-group literacy instruction. Educators’ beliefs and feelings of self-efficacy were not associated with the use of small-group literacy instruction. Practice or Policy: Educators may be better able to provide small-group literacy instruction in contexts affording low adult:child ratios and high levels of classroom management and instructional support, all of which are malleable factors that can be changed via policy or professional development.     

Women Faculty of Color: Stories Behind the Statistics

In this qualitative study we address two primary research questions: What are the experiences of women faculty of color (WFOC) who departed the tenure track at predominantly White, research universities? Using the modified lens of the newcomer adjustment framework, what socialization factors may have contributed to the WFOCs’ departure? Through a longitudinal, in-depth examination of three WFOC who left their university prior to earning tenure, themes of gendered and racialized tokenization and isolation, a need for a more intrusive style of mentoring, and poor institutional fit were identified. Implications for future research on faculty members’ social identity and promising practices for faculty development are shared.     

Patient and Partner Strategies for Talking about Lifestyle Change Following a Cardiac Event

Heart patients are frequently advised to make lifestyle changes and communication with a romantic partner can help or hinder adoption of heart healthy behaviors. However, talking about lifestyle change can have both positive and negative meanings and this can create dilemmas for couples. We engaged in an interpretive analysis of interviews with 25 patients and 16 partners to identify the ways they managed the meanings of lifestyle change talk. Their communicative strategies included rationing talk, saying it nicely and framing it cooperatively. Each strategy had advantages and disadvantages as well as optimal conditions. We also identified interpretive lenses that shaped the meaning of talk, including legitimacy, patience, emphasizing the positive, moderation, benefits for both people, and perceived compliance. Finally, environmental resources (such as household patterns and communication with the social network) contextualized the meaning of talk. We proposed a model of the interrelated influence of communication, interpretation, and environment on the meanings of talking about lifestyle change.     

Student formation in higher education: teachers’ approaches matter

Teaching in higher education encompasses more than merely helping students develop knowledge and skills. It entails engaging students in their own formation as persons, professionals and citizens. From this perspective, this article investigates how approaches to teaching academic writing contribute to formation. By analysing a case from initial teacher education in Norway, we identify and examine one teacher educator’s beliefs about writing and his approaches to teaching writing. Theoretical framework rests on six discourses of writing developed by Roz Ivani? and on the formative possibilities and constraints embedded in these different literacy discourses. Thus, we provide students’ experien-ces with this teacher’s approaches and discuss what formation his approaches seem to have initiated. The findings point to the need for more critical reflection on the formative impact of teaching approaches in higher education more generally.     

Foster Mother–Infant Bonding: Associations Between Foster Mothers' Oxytocin Production,Electrophysiological Brain Activity,Feelings of Commitment,and Caregiving Quality

This study examined the biological processes associated with foster mother–infant bonding. In an examination of foster mother–infant dyads (N = 41, mean infant age = 8.5 months), foster mothers' oxytocin production was associated with their expressions of behavioral delight toward their foster infant and their average P3 response to images of all infant faces in the first 2 months of the relationship. Three months later, foster mothers' oxytocin production was still associated with delight toward their foster infant and was also specifically associated with their P3 response to an image of their foster infant. Similar to biologically related mothers and infants, oxytocin appears to be associated with foster mothers' brain activity and caregiving behavior, with patterns suggestive of bond formation.     

Consistently inconsistent: An examination of the variability in the identification of emotional disturbance

The federal definition of emotional disturbance (ED) has been heavily criticized as vaguely defined and poorly operationalized yet there has not been a formal analysis of the reliability of the ED criteria. This study examined the reliability of the federal criteria for a special education designation of ED. A total of 179 school psychologists reviewed a mock special education report, made an eligibility determination, and provided information about their eligibility decision. In all, 56 participants found the student met ED eligibility criteria using 16 different combinations of the five criteria. Krippendorff’s α, a statistic preferred for content analysis, was calculated as a measure of criterion reliability. Results indicated extremely poor reliability (α = 0.2011). These findings demonstrate the importance of redefining the existing criteria.
