We designed an interrupted case study to teach aerobic cellular respiration to major and nonmajor biology students. The case is based loosely on a real-life incident of rotenone poisoning. It places students in the role of a coroner who must determine the cause of death of the victim. The case is presented to the students in four parts. Each part is followed by discussion questions that the students answer in small groups prior to a classwide discussion. Successive parts of the case provide additional clues to the mystery and help the students focus on the physiological processes involved in aerobic respiration. Students learn the information required to solve the mystery by reading the course textbook prior to class, listening to short lectures interspersed throughout the case, and discussing the case in small groups. The case ends with small group discussions in which the students are given the names and specific molecular targets of other poisons of aerobic respiration and asked to determine which process (i.e., glycolysis, citric acid cycle, or the electron transport chain) the toxin disrupts.  相似文献

Engaging with ‘English in a Historical Perspective’ Through Analysing Texts     

Mark Wyatt  Dorothy Constantino  Corinne Cox  Kristy Gilkes  Serena Thompson  Rachael Tiller 《Changing English: An International Journal of English Teaching》2016,23(1):22-41

Though there is little in the literature on the teaching of the history of English, criticism of textbooks which over-simplify the story as the rise of the standard variety has been more vocal of late. Meanwhile, some academics have argued for focusing teaching on the analysis of texts. This article reports on a unit/module taught at a British university that makes the analysis of texts central to teaching and assessment. It sets out to demonstrate what can be learned from approaching the subject in this way by presenting composite textual analyses created by the first-named author drawing on the work of his co-authors (five of his final-year undergraduate students). This was for two assignments, one focusing on an Early Modern English text and the other a more contemporary piece. A discussion highlights the benefits of making the analysis of texts central to the unit, and considers practical applications for teachers of the subject in other parts of the world.  相似文献   

Is the Poor Performance of Self‐Worth Protective Students Linked with Social Comparison Goals?     

Ted Thompson  Zoe Perry 《教育心理学》2005,25(5):471-490

Students motivated to protect self‐worth perform poorly in situations that threaten to reveal low ability while performing well in situations that involve little threat to self‐worth. One factor contributing to their poor performance is thought to be their orientation towards social comparison goals (goals that have to do with vindicating their ability relative to others rather than pursuing mastery). In the present study, 96 undergraduate students who were either high or low in self‐worth protection were exposed to either success or failure feedback and subsequently primed to pursue either social comparison or mastery goals. For students high in self‐worth protection, the negative effects of either failure or social comparison goal priming is sufficient to give rise to poor performance. However, only when success is combined with mastery goal priming is a positive achievement outcome evident. The requirements of best practice approaches to encouraging students to adopt mastery‐orientated behaviours are discussed.  相似文献

Enhancing Elementary Pre-service Teachers’ Plant Processes Conceptions     

Stephen L. Thompson  Christine Lotter  Xumei Fann  Laurie Taylor 《Journal of Science Teacher Education》2016,27(4):439-463

Researchers examined how an inquiry-based instructional treatment emphasizing interrelated plant processes influenced 210 elementary pre-service teachers’ (PTs) conceptions of three plant processes, photosynthesis, cellular respiration, and transpiration, and the interrelated nature of these processes. The instructional treatment required PTs to predict the fate of a healthy plant in a sealed terrarium (Plant-in-a-Jar), justify their predictions, observe the plant over a 5-week period, and complete guided inquiry activities centered on one of the targeted plant processes each week. Data sources included PTs’ pre- and post-predictions with accompanying justifications, course artifacts such as weekly terrarium observations and science journal entries, and group models of the interrelated plant processes occurring within the sealed terraria. A subset of 33 volunteer PTs also completed interviews the week the Plant-in-a-Jar scenario was introduced and approximately 4 months after the instructional intervention ended. Pre- and post-predictions from all PTs as well as interview responses from the subgroup of PTs, were coded into categories based on key plant processes emphasized in the Next Generation Science Standards. Study findings revealed that PTs developed more accurate conceptions of plant processes and their interrelated nature as a result of the instructional intervention. Primary patterns of change in PTs’ plant process conceptions included development of more accurate conceptions of how water is used by plants, more accurate conceptions of photosynthesis features, and more accurate conceptions of photosynthesis and cellular respiration as transformative processes.  相似文献   

Afro-Caribbean Immigrant Faculty Experiences in the American Academy: Voices of an Invisible Black Population     

Dave A. Louis  Keisha V. Thompson  Patriann Smith  Hakim Mohandas Amani Williams  Juann Watson 《The Urban Review》2017,49(4):668-691

Afro-Caribbean immigrants have been an integral part of the history and shaping of the United States since the early 1900s. This current study explores the experiences of five Afro-Caribbean faculty members at traditionally White institutions of higher education. Despite the historical presence and influence of Afro-Caribbean communities and the efforts within education systems to address the needs of Afro-Caribbean constituents, Afro-Caribbean faculty members continue to be rendered indiscernible in higher education and to be frequently and erroneously perceived as African–Americans. The study examines the lived experiences of these individuals in the hegemonic White spaces they occupy at their institutions with both White and Black populations. Through their narratives, issues of stereotyping, microaggression, and isolation are addressed. The participants also offer solutions to address these issues by university administrators, department heads, faculty development professionals, diversity officers, policy makers, and other stakeholders. The voices in this study shed light on an overlooked, misunderstood, and under-researched population within our faculty ranks in the American Academy.  相似文献   

Seeing Is Believing: Effective Components of Professional Development Training for County Extension Educators on an Innovation Perceived as Risky—Food Irradiation     

B.M. Thompson  J.F. Schielack  T.A. Vestal 《Journal of Food Science Education》2004,3(4):54-58

ABSTRACT: Decades of research have provided evidence that food irradiation is a safe technology that can decrease the incidence of foodborne diseases; however, adoption of this technology has been slow. The purpose of our study was to qualitatively explore the effectiveness of various components of a professional development training on family and consumer sciences county extension educators' understanding of food irradiation. This training included presentations by experts in the field, a tour of a food irradiation research facility and a meat processing facility, group activities, and a computer simulation model. Data were collected using qualitative research methodology through in-depth interviews conducted after the training. Results indicated that those components that allowed participants to visualize food irradiation processes seemed most beneficial to their understanding. Based on these data, implications for practice are discussed.  相似文献   

Journal Editorial Policies Regarding Statistical Significance Tests: Heat Is to Fire as p Is to Importance     

Bruce Thompson 《Educational Psychology Review》1999,11(2):157-169

The present paper responds to defenses of statistical significance testing offered by Levin and Robinson. First, some inaccurate perceptions of contemporary criticisms of statistical tests are noted. Second, areas of disagreement are explored. For example, it is noted that all nine empirical studies of reporting practices since 1994 show that encouraging (per the 1994 APA style manual) authors to report effect sizes has not worked; two reasons for this failure are explored. Finally, two important areas of agreement regarding needed improvements in contemporary practices are noted.  相似文献   

Association between self-reported health and physical and/or sexual abuse experienced before age 18     

Bonomi AE  Cannon EA  Anderson ML  Rivara FP  Thompson RS 《Child abuse & neglect》2008,32(7):693-701

OBJECTIVE: The present study evaluated the association between women's health and physical and sexual abuse suffered before age 18. METHODS: A total of 3,568 randomly sampled insured women ages 18-64 completed a telephone interview to assess history of physical only, sexual only, or both physical and sexual abuse before age 18 (Behavioral Risk Factor Surveillance System); and current health (Short Form-36, Center for Epidemiologic Studies-Depression, Presence of Symptoms surveys). Adjusted analyses compared the health of women with physical abuse only, sexual abuse only, or physical and sexual abuse to the health of women without these abuse histories. RESULTS: Poorest health status was observed in women with a history of both physical and sexual child abuse compared to women without these abuse histories. In models that adjusted for age and income, women with both abuse types had increased prevalence of depression (prevalence ratio, 2.16), severe depression (PR, 2.84), physical symptoms (PR range, 1.33 for joint pain to 2.78 for nausea/vomiting), fair/poor health (PR, 1.84), and lower SF-36 scores (3.15-5.40 points lower). Women with physical abuse only or sexual abuse only also had higher prevalence of symptoms and lower SF-36 scores but the associations were not as strong. CONCLUSIONS: This study adds to the literature showing a graded association between multiple adverse events in childhood and adult health.  相似文献
