As new communication technologies enter the classroom, teachers must attend to how digital platforms impact the interpersonal practices of teaching and learning. In this article, I study email exchanges with three of my students – Jorge, Adriana, and Jason – over the course of one year in an 11th-grade English class at River High School, a struggling American school subject to intervention for failing to meet the federal No Child Left Behind requirements. I ask several questions: what role does email play in my relationships with students; what does email reveal about the ideological content of my communication with students; and how could I use email transformatively? When I studied these email exchanges, I found that while email has the potential to transform literacy instruction, it can also perpetuate a poor student/teacher relationship and reproduce neoliberal narratives that narrowly imagine students as test-takers, workers, and consumers. 相似文献

The aims of this study were to describe and determine the test-retest reliability of an exercise protocol, the Loughborough Intermittent Shuttle Test (the LIST), which was designed to simulate the activity pattern characteristic of the game of soccer. The protocol consisted of two parts: Part A comprised a fixed period of variable-intensity shuttle running over 20 m; Part B consisted of continuous running, alternating every 20 m between 55% and 95% VO 2max , until volitional fatigue. Seven trained games players (age 21.5 +/- 0.9 years, height 182 +/- 2 cm, body mass 80.1 +/- 3.6 kg, VO 2max 59.0 +/- 1.9 ml kg -1 min -1 ; mean s x ) performed the test on two occasions (Trial 1 and Trial 2), at least7 days apart, to determine the test-retest reliability of the sprint times and running capacity. The physiological and metabolic responses on both occasions were also monitored. The participants ingested water ad libitum during the first trial, and were then prescribed the same amount of water during the second trial. The 15 m sprint times during Trials 1 and 2 averaged 2.42 +/- 0.04 s and 2.43 +/- 0.04 s, respectively. Run time during Part B was 6.3 +/- 2.0 min for Trial 1 and 6.1 +/- 1.3 min for Trial 2. The 95% limits of agreement for sprint times and run times during Part B were -0.14 to 0.12 s and -3.19 to 2.16 min respectively. There were no differences between trials for heart rate, rating of perceived exertion, body mass change during exercise, or blood lactate and glucose concentrations during the test. Thus, we conclude that the sprint times and the Part B run times were reproducible within the limits previously stated. In addition, the activity pattern and the physiological and metabolic responses closely simulated the match demands of soccer. 相似文献

The ways in which cooperating teachers give shape and meaning to their work in practicum settings is one of the most critical elements of initial teacher education. This international comparison draws upon surveys of Australian and Canadian cooperating teachers. The global contrast highlights taken‐for‐granted assumptions in local settings that in some instances are cause for celebration and in other instances concern. The comparison of the two settings illustrates, among other things: some striking similarities in the profiles of cooperating teachers; important differences with respect to the cooperating teachers' preparation and remuneration for their role in practicum settings; and deeper complexities regarding the relationship between schools and universities. 相似文献
