Engaged food science: Connecting K‐8 learners to food science while engaging graduate students in science communication

Connecting the public to concepts in science, technology, engineering, and mathematics (STEM) is an essential for technological advancement and inspiring future scientists, impacting both the communicator and the audience's understanding of scientific topics. Without proper communication of scientific knowledge, acceptance and implementation of new technologies can be hindered. Additionally, increasing public awareness about current scientific issues through STEM engagement permits more informed policy and consumer choices, especially in the field of food science where many new food technologies are met with initial resistance by the consuming public. Here, we describe an event that introduced topics in food science to the nonexpert public, including K‐8th grade participants and their adult caregivers in an informal learning environment. This program consists of six activities that collectively introduce three areas in food science: food chemistry, food microbiology, and process engineering. Protocols are provided for each activity including a materials list (with the option to scale up or down according to event duration, event space allowances, and number of participants), learning objectives and discussion points that are adaptable to different age groups, event spaces, or budgets. Each activity has a participatory component to ensure both audience member and instructor engagement. A program designed for food science communication empowers young scientific minds to better understand complex scientific topics and could inspire them to envision a possible career in STEM fields, with the additional benefit of providing graduate students an exciting medium through which they may practice their science communication skills, potentially benefiting not only their personal academic and professional skills but also broader societal needs.     

Fear of Death and Examination Performance in a Medical Gross Anatomy Course with Cadaveric Dissection

Cadaveric dissection offers an important opportunity for students to develop their ideas about death and dying. However, it remains largely unknown how this experience impacts medical students' fear of death. The current study aimed to address this gap by describing how fear of death changed during a medical gross anatomy dissection course and how fear of death was associated with examination performance. Fear of death was surveyed at the beginning of the course and at each of the four block examinations using three of the eight subscales from the Multidimensional Fear of Death Scale: Fear of the Dead, Fear of Being Destroyed, and Fear for the Body After Death. One hundred forty-three of 165 medical students (86.7%) completed the initial survey. Repeated measures ANOVA showed no significant changes in Fear of the Dead (F (4, 108) = 1.45, P = 0.222) or Fear for the Body After Death (F (4, 108) = 1.83, P = 0.129). There was a significant increase in students' Fear of Being Destroyed (F (4, 108) = 6.86, P < 0.0005) after beginning dissection. This increase was primarily related to students' decreased willingness to donate their body. Concerning performance, there was one significant correlation between Fear for the Body After Death and the laboratory examination score at examination 1. Students with higher fears may be able to structure their experience in a way that does not negatively impact their performance, but educators should still seek ways to support these students and encourage body donation.     

Individual Differences in the Stability and Change of Childhood Depression: A Growth Mixture Model With Structured Residuals

Studies of developmental trajectories of depression are important for understanding depression etiology. Existing studies have been limited by short time frames and no studies have explored a key factor: differential patterns of responding to life events. This article introduces a novel analytic technique, growth mixture modeling with structured residuals, to examine the course of youth depression in a large, prospective cohort (N = 11,641, ages 4–16.5, 96% White). Age-specific critical points were identified at ages 8 and 13 where depression symptoms spiked for a minority of children. Most depression risk was due to dynamic responses to environmental events, drawn not from a small pool of persistently depressed children, but a larger pool of children who varied across higher and lower symptom levels.     

Argument Types Affect Children’s Acquisition of a Novel Argument Structure

Acquisition of an argument structure may be affected by the diversity of lexical types that appear in that structure (Conwell et al., 2011; Yang, 2016). Seventy-two 5- and 6-year-old English-speaking children completed a learning study where they were exposed to a novel argument structure and then tested on their ability to comprehend it. The number of verb types heard in the learning phase did not predict comprehension at test. However, learning with only full noun phrase arguments resulted in lower comprehension of the structure, particularly with pronouns. Hearing pronouns during learning supported comprehension of all argument types at test. These results indicate that pronominal arguments support argument structure learning by providing multiple cues that can facilitate thematic role assignment.

Assessment of mathematics and reading performance: An examination of the correspondence between direct assessment of student performance and teacher report

Teacher judgments have been identified as a primary source of information regarding student academic achievement. Research examining the accuracy of teachers' judgments in assessing students' academic abilities has shown relatively high accuracy. However, previous studies have relied primarily on norm‐referenced measures to obtain estimates of students' achievement in reading and mathematics. Recent developments in the assessment of students' academic skills, such as Curriculum‐Based Measurement (CBM), provide a direct estimate of students' skill levels in basic areas such as reading and mathematics. The purpose of the present study was to examine the extent to which teachers' perceptions of students' reading and mathematics skills corresponded to direct estimates of students' reading and mathematics skills. Two second‐grade teachers estimated the reading and mathematics skills of 33 second‐grade students. Results of this study indicated that teachers were not accurate in assessing their students' mathematics functioning. Teachers were more accurate in assessing the occurrence of Mastery mathematics levels in basic addition, but were very inaccurate in assessing the occurrence of Mastery, Instructional, or Frustrational mathematics levels in all other skills assessed. In reading, teachers' judgment accuracy varied as a function of grade‐level material and instructional level. Specifically, teachers experienced considerable difficulty accurately identifying students who were reading at a Mastery level in grade‐level or above‐grade‐level material. © 2006 Wiley Periodicals, Inc.

“Don’t give up on me”: critical mentoring pedagogy for the classroom building students’ community cultural wealth

This one-year ethnographic case study focused on students of color from a West Coast High School who faced a variety of academic challenges. Collectively, they shared perspectives on school improvement, and among the recommendations was the importance of mentorship in the classroom to develop students’ aspirational, navigational, and informational capital for academic resiliency, high expectations, and success. This article highlights the perspectives of multiple stakeholders, such as students and teachers, on the qualities of mentorship practices. Using these data, a framework was developed to promote mentoring as an interrelated process in classroom instruction to ignite a new perspective on school reform. In this particular context, this study concludes that these students of color viewed mentorship as a critical component that was often missing in their high school careers. In an effort to improve students’ experiences in the classroom, this article argues that teachers must develop critical mentoring skills, beyond what is traditionally considered as mentoring services, as a pedagogical tool to assist students to overcome their academic challenges and achieve school success.     

Reading motivation and reading comprehension growth in the later elementary years

Reading motivation has been viewed as a multifaceted construct with multiple constituents. Our investigation of motivational multiplicity expanded on previous literature by including motivation constructs (interest, perceived control, collaboration, involvement, and efficacy), text genres, specific versus general contexts, and the self-versus other evidence sources about motivation. We expected that this multiplicity would influence the identification of reading comprehension growth predictors. We obtained pre- and post-interview data, teacher ratings, motivation self-reports, and reading comprehension scores. Interviews showed motivation constructs to be semi-independent. Students’ reading motivations for narrative and information texts were not highly associated; and self-reports and other motivation reports were not highly associated, but situated and general reading motivations were correlated. Interview-based coding of motivation predicted reading comprehension growth, but reading comprehension did not predict motivation growth. Situated motivation for information books predicted general motivation growth according to multiple regression analyses. Implications for an engagement model of reading development were discussed.
