What's Meat Got to Do with It? Some Considerations for Ecologizing Education with Respect to Diet

Even in a society of meat‐eaters such as the United States, when diet is addressed in school at all, it is widely treated as matter of personal choice, the consequences of which are borne by individual consumers. Overlooked are myriad connections involved in human diet and the implications of consumption for other entities. In the first part of this essay, Suzanne Rice discusses ways in which diet, particularly meat‐eating, is connected to animal suffering, environmental harms including climate change and pollution, and risks to the health of agricultural workers and consumers. In the second part, she discusses ways in which education might be “ecologized” in efforts to help students gain insight into such connections. There are many ways to ecologize education, but regardless of how teachers proceed, they are likely to encounter not only simple ignorance, relatively unproblematic gaps in students' knowledge linked to youth and inexperience, but also willful ignorance, more problematic gaps linked to avoidance, manipulation, or rejection of evidence perceived as threatening.     

Teachers’ perceptions of their most significant change: source,impact, and process

The purpose of the study was to examine the differences among significant changes in the practice of individual teachers. Seventeen US teachers were interviewed about the most successful change in their teaching career. The differences in teacher change were based primarily on the source and impact of the change. The sources of change were divided into two categories: other-initiated or self-initiated. The level of impact was determined in three ways: by whether teachers described a new practice, a new direction, or a change in their beliefs. By organizing according to both the source and impact of the change, four types of change were identified: Response to School Initiatives, Professional Development Initiatives, Student-Centered Changes, and Self-Designed Changes. Self-Designed changes were further distinguished based on the time required for the change process. Implications for developing new strategies to foster teacher development are discussed.     

TOWARD AN ARISTOTELIAN CONCEPTION OF GOOD LISTENING

In this essay Suzanne Rice examines Aristotle's ideas about virtue, character, and education as elements in an Aristotelian conception of good listening. Rice begins by surveying of several different contexts in which listening typically occurs, using this information to introduce the argument that what should count as “good listening” must be determined in relation to the situation in which listening actually occurs. On this view, Rice concludes, there are no “essential” listening virtues, but rather ways of listening that may be regarded as virtuous in the context of particular concrete circumstances.     

Using concept maps to assess student learning in the science classroom: Must different methods compete?

This yearlong study was implemented in seventh-grade life science classes with the students' regular teacher serving as teacher/researcher. In the study, a method of scoring concept maps was developed to assess knowledge and comprehension levels of science achievement. By linking scoring of concept maps to instructional objectives, scores were based upon the correctness of propositions. High correlations between the concept map scores and unit multiple choice tests provided strong evidence of the content validity of the map scores. Similarly, correlations between map scores and state criterion-referenced and national norm-referenced standardized tests were indicators of high concurrent validity. The approach to concept map scoring in the study represents a distinct departure from traditional methods that focus on characteristics such as hierarchy and branching. A large body of research has demonstrated the utility of such methods in the assessment of higher-level learning outcomes. The results of the study suggest that a concept map might be used in assessing declarative and procedural knowledge, both of which have a place in the science classroom. One important implication of these results is that science curriculum and its corresponding assessment need not be dichotomized into knowledge/comprehension versus higher-order outcomes. © 1998 John Wiley & Sons, Inc.

Teachers' perspectives on competency-based testing

The study described in this article was designed to gather information about teachers' perspectives on achievement testing and to describe where the competency-based testing in Continuous Uniform Evaluation Systems (CUES) programs fits into teachers' overall plans for teaching and assessing students.The specific objectives of the research were (1) to develop a taxonomy of techniques that teachers use to assess students, (2) to describe teachers' uses and perceptions of various assessment techniques, and (3) to describe the implementation of various assessment activities in natural classroom settings. The results of the study have implications for the design and implementation of instructional systems in school settings.     

Convergent validity of a novel method for quantifying rowing training loads

Elite rowers complete rowing-specific and non-specific training, incorporating continuous and interval-like efforts spanning the intensity spectrum. However, established training load measures are unsuitable for use in some modes and intensities. Consequently, a new measure known as the T2minute method was created. The method quantifies load as the time spent in a range of training zones (time-in-zone), multiplied by intensity- and mode-specific weighting factors that scale the relative stress of different intensities and modes to the demands of on-water rowing. The purpose of this study was to examine the convergent validity of the T2minute method with Banister’s training impulse (TRIMP), Lucia’s TRIMP and Session-RPE when quantifying elite rowing training. Fourteen elite rowers (12 males, 2 females) were monitored during four weeks of routine training. Unadjusted T2minute loads (using coaches’ estimates of time-in-zone) demonstrated moderate-to-strong correlations with Banister’s TRIMP, Lucia’s TRIMP and Session-RPE (rho: 0.58, 0.55 and 0.42, respectively). Adjusting T2minute loads by using actual time-in-zone data resulted in stronger correlations between the T2minute method and Banister’s TRIMP and Lucia’s TRIMP (rho: 0.85 and 0.81, respectively). The T2minute method is an appropriate in-field measure of elite rowing training loads, particularly when actual time-in-zone values are used to quantify load.     

Lessons from television: children's word learning when viewing

The study investigated if preschoolers can learn novel words when viewing television and if the learning is influenced by age or type of word. 61 preschoolers, ages 3 and 5, were assigned to either an experimental or control group. They viewed a 15-min television program, featuring 20 different novel words, 5 each in the 4 categories of object, action, attribute, and affective-state words. Comprehension was tested before and after viewing. The experimental group performed better than the controls for object, action, and attribute words. 5-year-olds were more accurate than 3-year-olds and gained relatively more from the experimental condition. The easiest words to learn were object and attribute words. The results are relevant for studies of media effects and accounts of preschoolers' "fast mapping" of new words.
