Science starts early: A literature review examining the influence of early childhood teachers’ perceptions of gender on teaching practices

Women are underrepresented in science fields as compared to men and although much research has been dedicated to understanding this disparity, most has been conducted on older aged children. However, this excludes the youngest and arguably most impressionable group of students: preschoolers. This study reviewed the literature to investigate how early childhood teachers’ perceptions of gender influence their teaching practices. Qualitative analysis and coding of 31 articles resulted in five main categories: Teacher Perception, Curriculum, Teacher Interactions, Gender Identity, and Social Standing. Results are discussed in the context of early childhood science teaching practices to better understand the role of the teacher and gender bias in young children’s preschool science experiences and how it may impact their future science interests

Toddler Play Preferences and the Teacher’s Role in the Outdoor Play Environment

Direct experience with nature is a primary component of environmental education and especially beneficial for young children. The present study examined the outdoor play preferences of toddlers and investigated the role teachers play in the outdoor space. Toddlers’ outdoor play was video recorded by GoPro cameras and coded for preferred play locations and initiator of the play. Results showed that the three most preferred spaces for toddlers in the outdoor classroom were the sandbox, swing area, and play structures; least frequently visited were open areas close to the classrooms, the garden, and the tree area. In addition, toddlers initiated play 71% of the time whereas teachers initiated approximately 11% of the time and mostly in the swing area. Findings indicate that teachers may play a role in where toddlers prefer to play. Implications for teacher preparation regarding environmental education are discussed

Communication with families: Understanding the perspectives of early childhood teachers

Communication between teachers and families in early childhood is a key aspect of successful teacher-family engagement. The goal of this exploratory study was to investigate how teachers communicated with families in early childhood classrooms and what they communicated about. This study of 31 teachers working with children birth to age five, primarily in the Midwestern U.S. examined how they described communication with families using semi-structured interviews. Findings indicated that teachers used multiple formats to communicate with families about children’s daily routines, developmental progress, and other relevant information. Teachers preferred in-person communication although challenges occurred due to classroom dynamics and the global COVID-19 pandemic restrictions. Technology such as apps and messaging emerged as an efficient way to reach most families, however difficulties facilitating reciprocal communication with families were described. Further research is needed to identify successful communication strategies for both teachers and families, thus building higher quality teacher-family partnerships

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Global Retinoblastoma Presentation and Analysis by National Income Level.

Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. Objectives: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. Design, Setting, and Participants: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. Main Outcomes and Measures: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. Results: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n = 3685 [84.7%]) were from low- and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 [62.8%]), followed by strabismus (n = 429 [10.2%]) and proptosis (n = 309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 [95% CI, 12.94-24.80], and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 [95% CI, 4.30-7.68]). Conclusions and Relevance: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs

The global retinoblastoma outcome study : a prospective, cluster-based analysis of 4064 patients from 149 countries

DATA SHARING : The study data will become available online once all analyses are complete.BACKGROUND : Retinoblastoma is the most common intraocular cancer worldwide. There is some evidence to suggest that major differences exist in treatment outcomes for children with retinoblastoma from different regions, but these differences have not been assessed on a global scale. We aimed to report 3-year outcomes for children with retinoblastoma globally and to investigate factors associated with survival. METHODS : We did a prospective cluster-based analysis of treatment-naive patients with retinoblastoma who were diagnosed between Jan 1, 2017, and Dec 31, 2017, then treated and followed up for 3 years. Patients were recruited from 260 specialised treatment centres worldwide. Data were obtained from participating centres on primary and additional treatments, duration of follow-up, metastasis, eye globe salvage, and survival outcome. We analysed time to death and time to enucleation with Cox regression models. FINDINGS : The cohort included 4064 children from 149 countries. The median age at diagnosis was 23·2 months (IQR 11·0–36·5). Extraocular tumour spread (cT4 of the cTNMH classification) at diagnosis was reported in five (0·8%) of 636 children from high-income countries, 55 (5·4%) of 1027 children from upper-middle-income countries, 342 (19·7%) of 1738 children from lower-middle-income countries, and 196 (42·9%) of 457 children from low-income countries. Enucleation surgery was available for all children and intravenous chemotherapy was available for 4014 (98·8%) of 4064 children. The 3-year survival rate was 99·5% (95% CI 98·8–100·0) for children from high-income countries, 91·2% (89·5–93·0) for children from upper-middle-income countries, 80·3% (78·3–82·3) for children from lower-middle-income countries, and 57·3% (52·1-63·0) for children from low-income countries. On analysis, independent factors for worse survival were residence in low-income countries compared to high-income countries (hazard ratio 16·67; 95% CI 4·76–50·00), cT4 advanced tumour compared to cT1 (8·98; 4·44–18·18), and older age at diagnosis in children up to 3 years (1·38 per year; 1·23–1·56). For children aged 3–7 years, the mortality risk decreased slightly (p=0·0104 for the change in slope). INTERPRETATION : This study, estimated to include approximately half of all new retinoblastoma cases worldwide in 2017, shows profound inequity in survival of children depending on the national income level of their country of residence. In high-income countries, death from retinoblastoma is rare, whereas in low-income countries estimated 3-year survival is just over 50%. Although essential treatments are available in nearly all countries, early diagnosis and treatment in low-income countries are key to improving survival outcomes.The Queen Elizabeth Diamond Jubilee Trust and the Wellcome Trust.https://www.thelancet.com/journals/langlo/homeam2023Paediatrics and Child Healt

The Impact of Literacy Coaches on Teachers\u27 Beliefs and Practices

The field of literacy education has long been concerned with the question of how to help classroom teachers improve their practices so that students will improve as readers. Although there is consensus on what characterizes effective professional development, the reading research on which this consensus is based most often is small scale and involves direct support provided by university faculty. The South Carolina Reading Initiative is an exception: It is a statewide, site-based, large-scale staff development effort led by site-selected literacy coaches. Although university faculty provide long-term staff development to the coaches, the faculty are not directly involved with the professional development provided to teachers. In this study we sought to understand whether site-based, site-chosen literacy coaches could help teachers\u27 beliefs and practices become more consistent with what the field considers to be best practices. To understand teacher change, we used two surveys (Theoretical Orientation to Reading Profile, n = 817; South Carolina Reading Profile, n = 1,005) and case study research (n = 39) to document teachers\u27 beliefs and practices. We also had access to a state department survey (n = 1,428). Across these data, we found that teachers\u27 beliefs and practices became increasingly consistent with best practices as defined by standards set by the South Carolina State Department of Education, standards that were consistent with national standards. This suggests that large-scale staff development can affect teachers when the providers are site-based, site-selected literacy coaches
