Lectures are a commonly used teaching method in higher education, but there is significant debate about the relative merits of different classroom practices. Various classroom observation tools have been developed to try to give insight into these practices, beyond the simple dichotomy of “traditional lecturing versus active learning”. Here we review of a selection of classroom observation protocols from an ethological perspective, and describe how this informed the development of a new protocol, FILL+. We demonstrate that FILL+ can be applied reliably by undergraduate students after minimal training. We analysed a sample of 208 lecture recordings from Mathematics, Physics, and Veterinary Medicine and found a wide variety of classroom practices, e.g. on average lecturers spent 2.1% (±2.6%) of the time asking questions, and 79.3% (±19%) of the lecture talking, but individuals varied considerably. The FILL+ protocol has the potential to be widely used, both in research on effective teaching practices, and in informing discussion of pedagogical approaches within institutions and disciplines.

We demonstrate that FILL+ can be applied reliably by undergraduate students after minimal training. We analysed a sample of 208 lecture recordings from Mathematics, Physics, and Veterinary Medicine and found a wide variety of classroom practices, e.g. on average lecturers spent 2.1% (± 2.6%) of the time asking questions, and 79.3% (± 19%) of the lecture talking, but individuals varied considerably. The FILL+ protocol has the potential to be widely used, both in research on effective teaching practices, and in informing discussion of pedagogical approaches within institutions and disciplines.

ABSTRACTUnderstanding how students learn is crucial for helping them succeed. We examined brain function in 107 undergraduate students during a task known to be challenging for many students – physics problem solving – to characterize underlying neural mechanisms and determine how these support comprehension and proficiency. Further, we applied module analysis to response distributions, defining groups of students who answered using similar physics conceptions, and probed for brain differences linked with different conceptual approaches. We found integrated executive, attentional, visual motion, and default mode brain systems cooperate to achieve sequential and sustained physics-related cognition. While accuracy alone did not predict brain function, dissociable brain patterns were observed when students solved problems using different physics conceptions, and increased success was linked to conceptual coherence. Our analyses demonstrate that episodic associations and control processes operate in tandem to support physics reasoning, offering insight into effective classroom practices to promote student success.

In recent years horticulture programs at universities across the United States have experienced a decline in student numbers. Researchers at the Univ. of Florida and Texas A&M Univ. have developed a survey to gain insight into the influences on undergraduate students who major in horticulture. Five universities participated in the survey of undergraduate horticulture programs, these include the Univ. of Florida, Texas A&M Univ., Oklahoma State Univ., Univ. of Tennessee, and Kansas State Univ. Approximately 600 surveys were sent to the schools during the 1997 fall semester. The questionnaires were completed by horticulture majors and nonmajors taking classes in the horticulture departments. The survey consisted of two main sections. The first section examined student demographic information, high school history, university history and horticulture background and was completed by all students. Only horticulture majors completed the second section, which examined factors influencing choice of horticulture as a major. Results examine fundamental predictors in promoting student interest in horticulture, demographic variables that may influence student choice of major, and student satisfaction and attitude toward current collegiate horticulture programs. Findings from this study will provide insight into the status of post-secondary horticulture education and assist in identifying methods to increase student enrollment in horticulture programs across the country.

: Oligopeptide transporter 3 (OPT3) proteins are one of the subsets of OPT clade, yet little is known about these transporters. Therefore, homolog OPT3 proteins in several plant species were investigated and characterized using bioinformatical tools. Motif and co-expression analyses showed that OPT3 proteins may be involved in both biotic and abiotic stress responses as well as growth and developmental processes. AtOPT3 usually seemed to take part in Fe homeostasis whereas ZmOPT3 putatively interacted with proteins involved in various biological processes from plant defense system to stress responses. Glutathione (GSH), as a putative alternative chelating agent, was used in the AtOPT3 and ZmOPT3 docking analyses to identify their putative binding residues. The information given in this study will contribute to the understanding of OPT3 proteins’ interactions in various pathways and to the selection of potential ligands for OPT3s.

The psychological effect of the pandemic and measures taken in response to control viral spread are not yet well understood in university students; in-depth qualitative analysis can provide nuanced information about the young adult distress experience. Undergraduate students ( N = 624) in an early US outbreak “hotspot” completed an online narrative writing about the impact and distress experienced due to the COVID-19 pandemic. Data were collected April-May 2020. A random selection of 50 cases were sampled for thematic analysis. Nine themes were identified: viral outbreak distress, fear of virus contraction/transmission, proximity to virus, dissatisfaction with public response, physical distancing distress, social distancing distress, academic and school-related distress, disruptive changes in health behavior and routines, financial strain and unemployment, worsening of pre-existing mental health problems, and social referencing that minimizes distress. Future work is needed to understand the persistence of the distress, in addition to developing methods for assessment, monitoring, and mitigation of the distress.

Search Domain

The influences of task type on search of the World Wide Web using search engines without limitation of search domain were investigated. 9 graduate and undergraduate students studying psychology (1 woman and 8 men, M age = 25.0 yr., SD = 2.1) participated. Their performance to manipulate the search engines on a closed task with only one answer were compared with their performance on an open task with several possible answers. Analysis showed that the number of actions was larger for the closed task ( M = 91) than for the open task ( M = 46.1). Behaviors such as selection of keywords (averages were 7.9% of all actions for the closed task and 16.7% for the open task) and pressing of the browser's back button (averages were 40.3% of all actions for the closed task and 29.6% for the open task) were also different. On the other hand, behaviors such as selection of hyperlinks, pressing of the home button, and number of browsed pages were similar for both tasks. Search behaviors were influenced by task type when the students searched for information without limitation placed on the information sources.

Classical beam models do not account for partial restraint of anticlastic bending and are therefore inherently inaccurate. This article proposes a modification of the exact Bernoulli–Euler equation which allows for an exact prediction of the beam's deflection without the need of two-dimensional finite element calculations. This approach offers a substantial reduction in the computational effort, especially when coupled with a fast-solving schema like the circle-arc method. Besides the description of the new method and its validation, this article offers an insight into the somewhat disregarded topic of anticlastic bending by a short review of the published theories and a selection of representative numerical results.

Purpose The purpose of this paper is to evaluate the model of a rear pressure bulkhead with different design optimizations to meet the pressurized cabin requirements of an aircraft. Design/methodology/approach This paper presents the results of the static analysis of a dome-shaped rear pressure bulkhead model designed in Catia-v5. Numerical analysis of model meshed in hyper-mesh and solved using Opti-Struct for iterative design optimizations. Findings All the iterative models are analyzed at 9 Psi. Rear pressure bulkhead designed with L-section stringer shows better results than the model optimized with T-section stringer for the same thickness. The model optimized with L-shaped stinger also reduces the weight of the bulkhead without affecting the structural integrity. Practical implications It has been concluded in this paper that the selection of specific shapes of the stringers shows a significant influence on weight reduction. Originality/value This paper provides a topical, technical insight into the design and development of a rear pressure bulkhead. It also outlines the future development of dome-shaped rear pressure bulkhead.
