Environmental Education in Missouri

Abstract

One result of globalization is that more of what people consume comes from distant regions through complex transactions hidden from ordinary view. To illuminate such flows, scholars often trace commodity chains following one product from inception to sale. Although most of us cannot escape being involved in commodity chains, we can participate with greater or less responsibility. This article outlines the advantages of studying the coffee chain to understand its relationship to consumer choice and environmental issues.     

From an essential being to an actor’s becoming: political ecology transformational learning experiences in adult education

Adult education in political ecology entails critically and constructively observing the interactions among the actors involved in socioecological conflicts at global and local scales. This definition invites transcending environmental education and education for sustainability’s frontiers, examining the ontology, or the ‘place’, from where actors co-construct these conflicts. If actors don’t question the reified and divided assumptions of the ‘self’ and ‘reality’ at the base of these conflicts, the creative and transformative potential of becoming together cannot unfold. The transformational learning approach is a coherent way of addressing this challenge, as it promotes an ontological change in actors and their worldview. The training experience offered by the University of Santiago provides insights into how transformational education’s perspective can contribute to education in political ecology, inciting an acknowledgment of the self and the world as a complex and dynamic entanglement of actors.     

Determination of the prevalence of anabolic steroids, stimulants, and selected drugs subject to doping controls among elite sport students using analytical chemistry

Drug abuse by adolescents has been investigated in various surveys that reported correlations between age, gender, and activity. However, none of these studies included chemical analyses to help substantiate the statements of participants. In the present study, the urine specimens of 964 students (439 females, 525 males; mean age 22.1 years, s = 1.7), who applied to study sports sciences at university, were assessed for anabolic steroids, stimulants, and selected drugs prohibited in sports. In total, 11.2% of the urine specimens provided contained drugs covered by doping controls. The most frequently detected compound was the major metabolite of tetrahydrocannabinol (9.8%) followed by various stimulants related to amphetamine and cocaine (1.0%). Indications of anabolic steroid use were found in 0.4% of urine samples but originated from contraceptives containing norethisterone. The present study provided unambiguous data on the status quo of drug (ab)use by adolescents hoping for a career related to elite sport or sports sciences. No use of anabolic steroids was detected. However, evidence for stimulants and tetrahydrocannabinol administration was obtained, although not reported by any participant, which highlights the issue of under-reporting in surveys based solely on questionnaires.     

A closer look at integrated writing tasks: Towards a more focussed definition for assessment purposes

The use of integrated tasks is increasingly common in second language assessment in both high stakes and classroom contexts. However, because of the vague definition of what constitutes an integrated task, the types of tasks included in this area and the assessment of the resulting writing is highly varied. In this paper, we argue for a better definition of the term ‘integrated writing task’. We start by reviewing current definitions available in the literature, discuss the construct underlying integrated tasks and then propose a number of features which we feel need to be present in integrated tasks. We then propose a new, narrower definition of the term. We hope that this will result in better task design, improved assessment outcomes for test takers, more detailed test specifications, better replicability of research and a shared research agenda.     

Using New Technology to Comply with ADA Assistive Listening Requirements

Hearing loss impacts 17 percent of the U.S. population. Recent changes to the Americans with Disabilities Act may require updates to how libraries accommodate people with hearing loss. Assistive listening technologies, such as Hearing Loop, open up more opportunities for libraries to engage with and better serve individuals with hearing loss.     

Modellierung von Lehrerkompetenzen

This contribution will investigate both the subject-specific and the didactic competencies of trainee teachers for lower secondary education in mathematics on the basis of the study “Mathematics Teaching in the 21st Century (MT21)”, which compares criteria-based samples from Germany, Bulgaria, South Korea, Taiwan, Mexico and the USA. In order to analyze their strengths and weaknesses more precisely, the paper considers both traditional IRT-scaling of competencies, which involves a simple loading of test performance in mathematics and didactics of mathematics, and an alternative. Under the assumption that solving items concerning didactics of mathematics requires competencies in didactics of mathematics and mathematics itself, a double-barreled approach was used in the alternative. In a further elaboration of this model, knowledge of arithmetic, algebra, functions, geometry and stochastic was used as a set of further explanatory factors for solving the items. This third model, which presumes a hierarchical structure of teaching competencies, displays the best data fit. Only this model reflects the specialisms and focal points of the education and training systems in the countries participating in MT21 concerning the relative learning opportunities in mathematics and didactics of mathematics and concerning the five subject areas in the field of mathematics.     

Digital Media and Education: cognitive impact of information visualization

In this article I argue that, like other technological innovations, the rise of the digital information age is contributing to shape people's mode of cognition. I review the use of computers in teaching and learning in terms of their impact on our ability to (1) process parallel data, (2) access information in a non‐linear order, and (3) visualize information. I analyse some implications for education stressing the importance of focusing on the meaning and interpretation of information rather than on gathering or memorizing data. In addition, I contend that although hypertextuality is perceived to be dynamic for its engagement with multiple dimensions, it is also a highly mediated form of accessing information. The most significant innovation of the computer, however, is the return to a visually based representation of reality. Paradoxically, the digital visualization of information aids the understanding of abstract concepts while simultaneously increasing conceptual abstraction.     

Students’ Energy Concepts at the Transition Between Primary and Secondary School

Energy is considered both a core idea and a crosscutting concept in science education. A thorough understanding of the energy concept is thought to help students learn about other (related) concepts within and across science subjects, thereby fostering scientific literacy. This study investigates students’ progression in understanding the energy concept in biological contexts at the transition from primary to lower secondary school by employing a quantitative, cross-sectional study in grades 3–6 (N?=?540) using complex multiple-choice items. Based on a model developed in a previous study, energy concepts were assessed along four aspects of energy: (1) forms and sources of energy, (2) transfer and transformation, (3) degradation and dissipation, and (4) energy conservation. Two parallel test forms (A and B) indicated energy concept scores to increase significantly by a factor of 2.3 (A)/1.7 (B) from grade 3 to grade 6. Students were observed to progress in their understanding of all four aspects of the concept and scored highest on items for energy forms. The lowest scores and the smallest gain across grades were found for energy conservation. Based on our results, we argue that despite numerous learning opportunities, students lack a more integrated understanding of energy at this stage, underlining the requirement of a more explicit approach to teaching energy to young learners. Likewise, more interdisciplinary links for energy learning between relevant contexts in each science discipline may enable older students to more efficiently use energy as a tool and crosscutting concept with which to analyze complex content.     

Word length and word frequency affect eye movements in dyslexic children reading in a regular (German) orthography

We combined independently the word length and word frequency to examine if the difficulty of reading material affects eye movements in readers of German, which has high orthographic regularity, comparing the outcome with previous findings available in other languages. Sixteen carefully selected German-speaking dyslexic children (mean age, 9.5 years) and 16 age-matched controls read aloud four lists, each comprising ten unrelated words. The lists varied orthogonally in word length and word frequency: high-frequency, short; high-frequency, long; low-frequency, short; low-frequency, long. Eye movements were measured using a scanning laser ophthalmoscope (SLO). In dyslexic children, fixation durations and the number of saccades increased both with word length and word frequency. The percentage of regressions was only increased for low-frequency words. Most of these effects were qualitatively similar in the two groups, but stronger in dyslexic children, pointing to a deficient higher-level word processing, especially phonological deficit. The results indicate that reading eye movements in German children are modulated by the degree of difficulty, and orthographic regularity of the language can determine the nature of modulation. The findings suggest that, similar to Italian but unlike English readers, German children prefer indirect sub-lexical strategy of grapheme-phoneme conversion.
