The Ordering Challenge: An Online Game to Introduce Independent Demand Inventory Concepts

Students are put in the role of a manager who watches inventory levels decrease and must order at the right time and in the right quantity to minimize costs. This interactive game requires the students to race against time and has levels of increasing difficulty. It introduces the students to the concepts of holding cost, ordering cost, backlog cost, the sawtooth curve, reorder point, order quantity, ABC categorization, and continuous review systems. The game is simple and is available free online. An accompanying assignment is designed to guide the student's reflection process while playing the game.

Embedded Clinical Librarianship: Bringing Medical Reference Services Bedside

This article was written by Patti Gibbons and Debra A. Werner. Patti is the Head of Collection Management at the University of Chicago Library’s Special Collections Research Center and holds a MLIS from the University of Illinois and a MA from the University of Washington. Debra is the Librarian for Science Instruction & Outreach and Biomedical Reference Librarian at the University of Chicago Library and the University of Chicago’s Pritzker School of Medicine’s Director of Library Research in Medical Education and she holds a MLIS from Dominican University. This article covers an experimental project at the University of Chicago where the library’s medical librarian teamed up with the hospital’s clinical team during patient rounds to provide real-time reference services. The project’s effectiveness was studied by a medical student who found that the embedded librarian’s services improved the clinical team’s evidence-based medical decision-making abilities without increasing the length of bedside rounds.     

Assessment Practices: Empowering Mathematics and Science Teachers in Rural Secondary Schools to Enhance Student Learning

Aligned with recent changes to syllabuses in Australia is an assessment regime requiring teachers to identify what their students ‘know’ and ‘can do’ in terms of the quality of understanding demonstrated. This paper describes the experiences of 25 secondary science and mathematics teachers in rural schools in New South Wales as they explore the changing nature of assessment and its implications on their classroom practice. To help reconceptualise these changes, teachers were introduced to a cognitive structural model as a theoretical framework. Throughout the 2-year study, teachers attended a series of professional development sessions and received ongoing consultative support. Each session was taped and transcribed while interviews were conducted with each teacher at the end of both years. Analysis of these data using a grounded theory approach identified seven major components of teacher practice impacted by the study. The core component was questioning while the six contributing components were teachers’ pedagogical practices, attention to cognition, teaching strategies, assessment linked to pedagogy, classroom advantages for students, and classroom advantages for teachers. These findings represent a major shift in teachers’ perceptions of assessment from a focus on the accumulation of students’ marks to one of diagnosis as a means of directing teaching to enhance students’ scientific and mathematical understandings.     

Racial identity,maternal support,and psychological distress among African American adolescents

This study investigated the role of racial identity and maternal support in reducing psychological distress among African American adolescents. Both direct and indirect influences of multiple dimensions of racial identity (i.e., centrality, private regard) and maternal support on perceived stress, depressive symptoms, and anxiety were examined among 521 African American twelfth graders. Findings indicated that maternal support was positively related to both centrality and private regard. Results provided little support for a direct association between racial identity or maternal support and depressive symptoms and anxiety within a multivariate context. Rather, the influences of racial identity attitudes and maternal support on these mental health outcomes were mediated by perceived stress. Further, the two racial identity attitudes were associated with perceived stress in different ways. Study findings suggest that the significance and meaning that African American adolescents attribute to being Black may be critical to their psychological well-being, and that maternal support and perceived stress are important considerations.     

Coming to America: need for acculturation and media use motives among indian sojourners in the US

Many uses and gratifications scholars have called for more research on media use within various cultural contexts as a means of extending the understanding of motivations for media use and the resulting patterns of exposure. This study of 99 Asian Indian graduate students at a US university differentiates the mass media that these predominantly young, urban males used in India (prior to coming to the US) and in the US (after their arrival in the US). Via principal components analysis, the study also identifies eight motives for Indian students’ use of American television, including the motives of acculturation and reflection on values. The data show that need for acculturation is strongly correlated with the motives of acculturation and surveillance and moderately correlated with reflection on values and learning. Overall, motives for American television viewing shared 45% of their variance with need for acculturation, indicating the importance of the new culture's media in the acculturation process of sojourners.     

Teachers' Knowledge of Children's Mathematics after Implementing a Student-Centered Curriculum

Our study investigated the knowledge 13elementary teachers gained implementing astudent-centered curriculum in the context ofdistrict-wide reform. Participants comprisedall the teachers in grades three, four and fiveat a single elementary school. We believed thatinvestigating teachers' responses to fictionalpedagogical scenarios involving nonstandardalgorithms would yield insights into criticalcomponents of their knowledge base. We lookedin particular at teachers' knowledge of children's mathematics. We found that teacherswere in the midst of creating a knowledge basefocused on children's mathematics and groundedin knowledge about alternative conceptualtrajectories through the elementary curriculum.Teachers' knowledge of nonstandard strategiessupported by the curriculum materials wasstronger and more coherent than their knowledgeof students' novel nonstandard strategies.Strong mathematical knowledge was notnecessarily associated with strong knowledge ofchildren's mathematics. Teachers' thinkingvaried by a topic's treatment in the writtencurriculum materials used, suggestingimplementation of the curriculum as a source oflearning.     

College Students' Experiences of Childhood Developmental Traumatic Stress: Resilience,First‐Year Academic Performance,and Substance Use

Developmental trauma—distressing childhood experiences that include mistreatment, interpersonal violence, abuse, assault, and neglect—is associated with substance use and poor academic performance. The authors investigated the links between developmental trauma, grade point average, substance use, and resilience among first‐year college students (N = 169). The results indicate there is a significant relationship between cumulative trauma and self‐reported substance use.
