Developing and evaluating instructionally sensitive assessments in science

The purpose of this article is to address a major gap in the instructional sensitivity literature on how to develop instructionally sensitive assessments. We propose an approach to developing and evaluating instructionally sensitive assessments in science and test this approach with one elementary life‐science module. The assessment we developed was administered to 125 students in seven classrooms. The development approach considered three dimensions of instructional sensitivity; that is, assessment items should: represent the curriculum content, reflect the quality of instruction, and have formative value for teaching. Focusing solely on the first dimension, representation of the curriculum content, this study was guided by the following research questions: (1) What science module characteristics can be systematically manipulated to develop items that prove to be instructionally sensitive? and (2) Are the instructionally sensitive assessments developed sufficiently valid to make inferences about the impact of instruction on students' performance? In this article, we describe our item development approach and provide empirical evidence to support validity arguments about the developed instructionally sensitive items. Results indicated that: (1) manipulations of the items at different proximities to vary their sensitivity were aligned with the rules for item development and also corresponded with pre‐to‐post gains; and (2) the items developed at different distances from the science module showed a pattern of pre‐to‐post gain consistent with their instructional sensitivity, that is, the closer the items were to the science module, the larger the observed gains and effect sizes. © 2012 Wiley Periodicals, Inc.

A new approach to determining net impulse and identification of its characteristics in countermovement jumping: reliability and validity

Examining a countermovement jump (CMJ) force-time curve related to net impulse might be useful in monitoring athletes' performance. This study aimed to investigate the reliability of alternative net impulse calculation and net impulse characteristics (height, width, rate of force development, shape factor, and proportion) and validate against the traditional calculation in the CMJ. Twelve participants performed the CMJ in two sessions (48 hours apart) for test–retest reliability. Twenty participants were involved for the validity assessment. Results indicated intra-class correlation coefficient (ICC) of ≥ 0.89 and coefficient of variation (CV) of ≤ 5.1% for all of the variables except for rate of force development (ICC = 0.78 and CV = 22.3%). The relationship between the criterion and alternative calculations was r = 1.00. While the difference between them was statistically significant (245.96 ± 63.83 vs. 247.14 ± 64.08 N s, p < 0.0001), the effect size was trivial and deemed practically minimal (d = 0.02). In conclusion, variability of rate of force development will pose a greater challenge in detecting performance changes. Also, the alternative calculation can be used practically in place of the traditional calculation to identify net impulse characteristics and monitor and study athletes' performance in greater depth.     

Faculty and staff perceptions of undergraduate mentoring

ABSTRACT

The connection between students and faculty is a recognized component of student belonging and engagement. To better understand how these relationships are formed, we utilized a qualitative design to explore the ways in which faculty and staff at a mid-sized public university perceived their roles in supporting, and connecting with, students. Based on our focus group data, we identified three themes. The first theme defined the mentoring relationship in the university context. The second theme addressed the unique features of mentoring Underrepresented Minority (URM) and First Generation (FG) students. Our third theme focused on perceived barriers to mentoring, including personal, institutional, and student-related barriers. Our findings provide a first step in developing a framework for colleges and universities working to promote a culture of mentoring as a means to support students.     

The "Illusion of Life" rhetorical perspective: an integrated approach to the study of music as communication

–The illusion of life rhetorical perspective increases our understanding about how discursive linguistic symbols and non-discursive aesthetic symbols function together to communicate and persuade in didactic music. We argue that lyrics and music work together to offer messages comprised of both conceptual and emotional content through the constructs of virtual experience (lyrics) and virtual time (music). Both virtual experience and virtual time must exist for music to function rhetorically. For songs without lyrics, virtual experience must be derived from some other source. Emotional content is progressively articulated in music and is understood by considering intensity and release patterns both individually and contextually. Music's rhetorical significance lies in the degree of congruity or incongruity that exists between virtual experience and virtual time. Congruent messages make the meaning more poignant, but could come at the expense of listener appeal. Incongruent messages transform the message in some way, making the holistic message more than, and perhaps different from, the message depicted in the lyrics alone. Incongruity could result in misinterpretation, an emotional message devoid of conceptual content, or subtle and systematic persuasion.     

Early Childhood Educators' Perceptions of Nature,Science, and Environmental Education

This study examined early childhood educators' perceptions about nature, science, and environmental education. Preservice early childhood teachers (n = 195) and early childhood professionals currently practicing in the field (n = 162) rated the importance of providing specific nature/science experiences for young children, the importance of specific nature/science learning outcomes, and their confidence implementing specific activities. Research Findings: Consistent with our hypotheses, both professionals and students rated the curricular domain of nature/science as the least important for young children in terms of experiences and learning outcomes in comparison to other curricular domains. Similarly, both professionals and students reported that they were least confident implementing nature/science activities compared to activities in other curricular domains. Qualitative analysis of open-ended questions yielded themes related to definitions of nature, specific activities in and about nature that can promote children's learning and development, and what educators need to know and be able to do in order to be effective “nature educators.” Practice or Policy: Preservice and in-service teacher professional development would benefit from (a) the inclusion of content on nature, science, and environmental education, including the interrelatedness of human and natural systems; (b) a focus on place-based education and/or emergent curriculum; and (c) the provision of experiences in nature that help teachers to develop confidence implementing activities in nature.

Change Within a Teacher Education Program and Laboratory: A Reflective Commentary

Intentional, systemic philosophical change on an educational program level and on an individual level is often a slow and cyclic process. In this article, we reflect on the journey of philosophical change and growth from a traditional philosophy to an inquiry-based, Reggio-inspired one that occurred on both levels in an early childhood teacher education program and laboratory school over a period of 7 years. As an inquiry group, we reflected on the change we experienced in our own teaching methods, our interactions with staff members and each other, and our perceptions of change in interaction with our students. After carefully and systematically reviewing our reflections, five trends in change were identified. They were (a) recasting the image of the teacher and reevaluating the process of teaching and learning, (b) valuing dialogue, (c) cultivating a reflective mindset, (d) valuing outside perspectives, and (e) building meaningful relationships. The process of reflecting on and documenting our journey has improved our ability to articulate the change we made and to see our growth. Further it has illuminated future teaching and learning directions and aims that we intend to pursue. Finally, we hope that sharing this process will encourage others to examine what, how, and why of their teaching and learning in order to enhance their own professional development journey.
