Emotions like regret and envy share a common origin: they are motivated by the counterfactual thinking of what would have happened had we made a different choice. When we contemplate the outcome of a choice we made, we may use the information on the outcome of a choice we did not make. Regret is the purely private comparison between two choices that we could have taken, envy adds to this the information on outcome of choices of others. However, envy has a distinct social component, in that it adds the change in the social ranking that follows a difference in the outcomes. We study the theoretical foundation and the experimental test of this view.  相似文献

The COVID‐19 global pandemic caused instructors to pivot to remote and online teaching, an especially challenging task in hands‐on classes such as invertebrate biology. In this special 25th anniversary issue of Invertebrate Biology, the authors present a variety of clever and effective ways to help invertebrate biology instructors adapt to teaching in an online environment. Student‐centered research and learning are essential in all biology classes, and we explore scientific writing, field trips, do‐it‐yourself laboratories, and more. These techniques will be useful for classes of varying sizes and types, from non‐major undergraduates to graduate students, even after the pandemic is over. Innovation for teaching invertebrate biology online may help facilitate more inclusive courses that serve diverse students more equitably. Ideas for how to best move traditionally hands‐on laboratories into online or remote formats are currently also being informally discussed in a collaborative online space for instructors.  相似文献

Since the time of Charles Darwin, studies of interspecific hybridization have been a major focus for evolutionary biologists. Although this phenomenon has often been viewed as problematic in the fields of ecology, taxonomy and systematics, it has become a primary source of data for studies on speciation and adaptation. Effects from genetic/evolutionary processes, such as recombination and natural selection, usually develop over extended periods of time; however, they are accelerated in cases of hybridization. Interspecific hybrids exhibit novel genomes that are exposed to natural selection, thus providing a key to unravel the ultimate causes of adaptation and speciation. Here we provide firstly a historic perspective of hybridization research, secondly a novel attempt to assess the extent of hybridization among animals and thirdly an overview of the reviews and case studies presented in this theme issue.  相似文献

First‐year majors organismal biology courses are frequently taught as survey courses that promote memorization rather than synthesis of biological concepts. To address the shortcomings of this approach, we redesigned the organismal portion of our introductory biology curriculum to create a “Foundations of Form and Function” course. Foundations of Form and Function introduces different organismal forms and focuses on the relationship between those forms and the execution of key physiological functions. Goals of our new course include the following: developing student recognition of common characteristics that unite living organisms as well as features that distinguish taxonomic groups, facilitating student understanding of how organisms accomplish similar functions through different forms, and reinforcing course themes with independent student research. In this paper, we describe course learning outcomes, organization, content, assessment, and laboratory activities. We also present student perspectives and outcomes of our course design based on data from four years of student evaluations. Finally, we explain how we modified our course to meet remote learning and social‐distancing challenges presented by the COVID‐19 pandemic in 2020 and 2021.  相似文献

This article contributes to the field of anthropological pedagogy, adding to recent articles regarding needed change in anthropology teaching methods. All have in common the practice of anthropology in the classroom. The author used the theory of optimal foraging to encourage students to operationalize human behavior. The economic benefit that students reaped warrants discussion. Students rapidly and measurably improved several areas of their lifestyle including health, finance, and home. Pursuing an anthropology degree thus becomes a personal journey.  相似文献

We reviewed 2524 articles published from 1987 to 1995 in five international journals, Conservation Biology , Biological Conservation , Biodiversity and Conservation , Ecological Applications , and the Journal of Applied Ecology , to assess patterns and imbalances in biodiversity research in the following subject areas: locations where research was conducted, types of organisms studied, types of ecosystems studied, types of methodologies used, and types of stresses investigated. Biodiversity research was found to be narrowly focused with little deviation from its initial course set of being a discipline concerned largely with the implications of forest habitat loss on charismatic terrestrial megafauna; i.e. the 'founder effect' is very much in evidence. The 'sleeping dragon' of ignored marine biodiversity is really symptomatic of a wider problem, and can perhaps be referred to as a 'hibernating hydra' of many imbalances due to, for example, under-representations of research from developing nations, or on amphibians and invertebrates, alpine and arctic systems, sociological components and chemical stresses etc. It is time to take steps to actively awaken the creature so that conservation biology/applied ecology can become more pluralistic in scope.  相似文献

As education methodology has grown to incorporate online learning, disciplines with a field component, like ecology, may find themselves sidelined in this transition. In response to challenges posed by moving classes online, previous studies have assessed whether an online environment can be effective for student learning. This work has found that active learning structures, which maximize information processing and require critical thinking, best support student learning. All too commonly, online and active learning are perceived as mutually exclusive. We argue the success of online learning requires facilitating active learning in online spaces. To highlight this intersection in practice, we use a case study of an online, active, and synchronous ecology and conservation biology course from the College of Natural Sciences at Minerva Schools at KGI. We use our perspectives as curriculum designers, instructors, and students of this course to offer recommendations for creating active online ecology courses. Key components to effective course design and implementation are as follows: facilitating critical “thinking like a scientist”, integrating open‐ended assignments into class discussion, and creating active in‐class dialogues by minimizing lecturing. Based on our experience, we suggest that by employing active learning strategies, the future of ecology in higher education is not inhibited, but in fact supported, by opportunities for learning online.  相似文献

We examined selected situational emotions (interest, well-being and anxiety) experienced by 291 secondary school tenth graders during a hands-on gene technology lesson. Two different instruction groups (I-1, I-2) participated in the same teaching unit, in which four basic gene technology experiments were performed. Using a modified ‘constructivist teaching sequence’, a teacher confronted group I-2 with the alternative conceptions of their peers regarding central issues and processes of gene technology in addition to providing the scientific concepts. The pupils within the I-2 group scored higher in the positive emotions of interest and well-being. The negative emotion anxiety was almost absent in both instruction groups. Furthermore, our results indicate a potential influence of interest and well-being upon learning success. Pupils who felt fine and worked with interest in the experimental lessons scored significantly higher on the cognitive achievement test. Eliciting pupils’ alternative conceptions and using them in a wide variety of teaching contents is therefore advisable. By doing so, teachers could help create a classroom environment where pupils feel safe and confident. Also, a pupil’s interest regarding the choice of material needs to be taken into account if positive emotions need strengthening and the learning achievement needs improvement.  相似文献

Education for sustainability (EfS) in higher education is an emerging specialisation within the general field of EfS. EfS encompasses cognitive, affective and behavioural aspects, and aims at enhancing a variety of learning outcomes in these domains and reaching students from all programmes. One of the main challenges for higher education educators is to design courses in a way that will effectively promote the various learning outcomes of EfS. A central question is how sustainability should be integrated into the curriculum; which topics should be taught and which pedagogies ought to be applied to improve students’ knowledge, skills and motivation to promote sustainable living. The present study aimed to contribute to the knowledge about students’ learning outcomes yielded by different designs of EfS courses. This multiple-case study of three courses used a mixed-methods design. For each course, we identified its characteristics and analysed students’ self-reported learning outcomes. We found that: (1) a course with a higher degree of participatory learning, employing a system approach, promoted the highest and most varied learning outcomes; (2) the lecture-based course yielded the fewest learning outcomes; and (3) field trips promoted learning outcomes only when accompanied by more advanced pedagogies.  相似文献

Our interpretative study that was carried out in a science and engineering oriented university examined the ways students in an introductory biology course perceived their learning in the course that was substantially changed to allow student-centered learning. The instructional change was framed by the view of learning as a sociocultural activity as well as a cognitive process that can take place face-to-face or through online interaction. Most of the lectures were substituted with individual learning and project-based, small-group learning that lasted one month. Data were collected through interviews with students and instructors, and through observations. In the paper, we show evidence for deep learning that was associated by the students and the instructors with short-term, meaningful activities in a setting that included collaborative peer learning; and replacing most lectures by small group learning that ended in a mini-conference. Deep learning was evidenced by the ways students reflected on how they organised and applied knowledge using deep learning strategies.  相似文献

Video displays for behavioral research lend themselves particularly well to studies with chimpanzees (Pan troglodytes), as their vision is comparable to humans', yet there has been no formal test of the efficacy of video displays as a form of social information for chimpanzees. To address this, we compared the learning success of chimpanzees shown video footage of a conspecific compared to chimpanzees shown a live conspecific performing the same novel task. Footage of an unfamiliar chimpanzee operating a bidirectional apparatus was presented to 24 chimpanzees (12 males, 12 females), and their responses were compared to those of a further 12 chimpanzees given the same task but with no form of information. Secondly, we also compared the responses of the chimpanzees in the video display condition to responses of eight chimpanzees from a previously published study of ours, in which chimpanzees observed live models. Chimpanzees shown a video display were more successful than those in the control condition and showed comparable success to those that saw a live model. Regarding fine-grained copying (i.e. the direction that the door was pushed), only chimpanzees that observed a live model showed significant matching to the model's methods with their first response. Yet, when all the responses made by the chimpanzees were considered, comparable levels of matching were shown by chimpanzees in both the live and video conditions.  相似文献

The association between circadian preference and academic achievement has been assessed through a systematic review and meta-analysis. The literature searches retrieved 1647 studies; 31 studies, with a total sample size of 27?309 participants, fulfilled the inclusion criteria and were included in the meta-analysis. With reference to all these 31 studies, before running the meta-analysis, the sign of the correlation between the investigated variables was set in a way that a positive correlation showed that eveningness was related to worse academic performance. The meta-analysis yielded a small overall effect size of 0.143 (CI [0,129; 0,156]) under a fixed effects model (Z?=?20.584, p?<?0.001, I2?=?72.656; Q?=?109.715) and of 0.145 (CI [0.117; 0.172]) under a random effects model (Z?=?10.077, p?<?0.001). A random effects model with a grouping variable (participants) revealed 15 studies based on school pupils and 16 on university students. The random model showed a higher effect size in school pupils (0.166, CI from 0.127 to 0.206) compared to university students (0.121, CI from 0.080 to 0.163). Self-report measures of grades revealed a stronger effect size (0.171; CI: 0.137 to 0.206; N?=?20) compared to objective measures (0.093; CI: 0.047 to 0.140; N?=?19). Overall, the present results suggest that evening orientation is associated with a worse academic performance, both in school pupils and university students; for the first time, it has been shown that such relationship changes over time, being weaker in university students.  相似文献

Numerous studies over the years have documented an effect of human chronotypes on physiological and psychological processes. Studies evaluating the impact of an individual’s chronotype on his/her academic achievement have indicated that morning chronotypes have an academic advantage over evening chronotypes. However, these studies did not account for the time of day in which the participants were being evaluated. The goal of the present study was to examine whether morning chronotypes do have an academic advantage over evening chronotypes when the time of day of classes and exams is taken into consideration. We obtained morningness–eveningness scores and course grades from 207 university students who took classes (and exams) at different times of the day. We confirmed that morning chronotypes attain better grades than evening chronotypes, although the association is weak (r2 = 0.02). The difference persisted even after the time of day of classes and exams was taken into consideration. This is probably due to the fact that evening chronotypes are generally more sleep deprived than morning chronotypes as a result of the early schedule of most schools, which can impair their performance both early and late in the day.  相似文献
