High school biology: What makes it a challenge for teachers?

This study contributes to our understanding of the complex issues inherent in dealing with the heterogeneity of current high school science classrooms, by reporting on in-depth interviews with 38 experienced biology teachers. Analyses of teachers' responses revealed complex and occasionally counter-intuitive relationships among: (a) their perceptions of what was distinctive about their school, its biology program, or their students; (b) their allocation of class time; (c) their efforts to individualize instruction and meet the needs of a heterogeneous student population; (d) their student outcome goals; and (e) the methods they used to evaluate student progress. Thus, for example, of the 9 teachers who cited the diversity of their students. 4 also commented on their poor motivation, but another 4 also commented on their high motivation. In addition, teachers reported using a similar range of instructional formats but for different reasons, depending on the characteristics of their students (e.g., cooperative learning groups used to compensate for poor attention spans, to challenge bright students, and to foster social tolerance). Discussion of these findings addresses several points of relevance for science education, teacher preparation, and curriculum reform. © 1996 John Wiley & Sons, Inc.     

Kinematic analysis of hip and knee rotation and other contributors to ballet turnout

Turnout, or external rotation (ER) of the lower extremities, is essential in ballet. The purpose of this study was to utilise physical examination and a biomechanical method for obtaining functional kinematic data using hip and knee joint centres to identify the relative turnout contributions from hip rotation, femoral anteversion, knee rotation, tibial torsion, and other sources. Ten female dancers received a lower extremity alignment assessment, including passive hip rotation, femoral anteversion, tibial torsion, weightbearing foot alignment, and Beighton hypermobility score. Next, turnout was assessed using plantar pressure plots and three-dimensional motion analysis; participants performed turnout to ballet first position on both a plantar pressure mat and friction-reducing discs. A retro-reflective functional marker motion capture system mapped the lower extremities and hip and knee joint centres. Mean total turnout was 129±15.7° via plantar pressure plots and 135±17.8° via kinematics. Bilateral hip ER during turnout was 49±10.2° (36% of total turnout). Bilateral knee ER during turnout was 41±5.9° (32% of total turnout). Hip ER contribution to total turnout measured kinematically was less than expected compared to other studies, where hip ER was determined without functional kinematic data. Knee ER contributed substantially more turnout than expected or previously reported. This analysis method allows precise assessment of turnout contributors.     

New media environments’ comparative effects upon intercultural sensitivity: A five-dimensional analysis

An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life^®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness.     

ROUSSEAU'S IMAGINARY FRIEND: CHILDHOOD,PLAY, AND SUSPICION OF THE IMAGINATION IN EMILE

In this essay Amy Shuffelton considers Jean‐Jacques Rousseau's suspicion of imagination, which is, paradoxically, offered in the context of an imaginative construction of a child's upbringing. First, Shuffelton articulates Rousseau's reasons for opposing children's development of imagination and their engagement in the sort of imaginative play that is nowadays considered a hallmark of early and middle childhood. Second, she weighs the merits of Rousseau's opposition, which runs against the consensus of contemporary social science research on childhood imaginative play. Ultimately, Shuffelton argues that Rousseau's work offers an important cautionary note to enthusiasts of children's imaginative play, due to the potentially disruptive influence of consumer capitalism, though she also notes that imagination may play a more redemptive role than Rousseau granted it.     

PRESERVICE TEACHER APPLICATION OF DIFFERENTIATED INSTRUCTION

Successfully implementing the practice of inclusion by differentiating instruction depends on both the skills and attitudes of general education teachers. New general education teachers who are entering the field are particularly vulnerable to the demands and stress of the profession, and teacher education programs must prepare preservice teachers to meet the needs of all students by teaching the skills needed to make appropriate lesson adaptations, accommodations, and modifications. This study investigates the manifestation of differentiation for special education students in work sample lesson plans written by preservice teachers working toward an elementary school credential. The research examined the nature, characteristics, and types of instructional adaptations included in the work samples prepared by a sample of preservice teachers resulting in six distinct themes and recommendations for teacher education programs.     

Early Literacy Measures for Improving Student Reading Achievement: Translating Research Into Practice

The importance of early literacy instruction and its role in later reading proficiency is well established; however, measures and procedures to screen and monitor proficiency in the area of early literacy are less well researched. The purpose of this study was to (a) examine the technical adequacy and validity of early curriculum-based literacy measures, Letter–Sound Correspondence, Onset Phoneme Identification, and Phoneme Segmentation, developed for use within the problem-solving model in the Minneapolis Public Schools and (b) describe the district-wide implementation of these measures. In general, these measures were found to have adequate reliability and validity, have moderate to moderately high correlations with criterion measures (oral reading, report cards), and be sensitive to growth across the school year. A case study of how these measures are used for screening and progress monitoring to improve reading achievement within 1 school is included. Limitations and future directions are also presented.     

Quality control in distance education: The role of regional accreditation

Abstract

Presidents wanting their institutions to maintain traditional educational primacy despite necessary changes occasioned by offerings made possible through technological innovations can rely upon the quality assurance mechanisms of their regional accrediting association. This article discusses how, by augmenting traditional standards as well as the process for their application, the associations address such areas as: the admission, promotion, and graduation of students; the availability of out‐of‐class services, including information resources; the integration of distance education programming into the institution as a whole; and public communication of the expectations, process, and results of distance education programming at an accredited institution.
