Assessing the influence of field- and GIS-based inquiry on student attitude and conceptual knowledge in an undergraduate ecology lab

Combining field experience with use of information technology has the potential to create a problem-based learning environment that engages learners in authentic scientific inquiry. This study, conducted over a 2-yr period, determined differences in attitudes and conceptual knowledge between students in a field lab and students with combined field and geographic information systems (GIS) experience. All students used radio-telemetry equipment to locate fox squirrels, while one group of students was provided an additional data set in a GIS to visualize and quantify squirrel locations. Pre/postsurveys and tests revealed that attitudes improved in year 1 for both groups of students, but differences were minimal between groups. Attitudes generally declined in year 2 due to a change in the authenticity of the field experience; however, attitudes for students that used GIS declined less than those with field experience only. Conceptual knowledge also increased for both groups in both years. The field-based nature of this lab likely had a greater influence on student attitude and conceptual knowledge than did the use of GIS. Although significant differences were limited, GIS did not negatively impact student attitude or conceptual knowledge but potentially provided other benefits to learners.     

Difficulties in Learning Thermodynamic Concepts Are They Linked to the Historical Development of this Field?

Students' misunderstanding of basic thermodynamic concepts is analysed on historicalgrounds. The persistence of some ideas from the caloric model are found to be reinforced bymagnitude names and unit definitions that were brought up at the early stages of thermodynamic development. The failure of many popular textbooks to make a clear distinction between internal energy and heat is also explored and related to Students' learning difficulties. Some hints that may help to improve Students' understanding are presented.

Communication in Online Learning – How Important is It?

Abstract

The purpose of this transcendental phenomenological study was to describe teacher experiences of teacher-to-student technology-mediated communication (TMC) in secondary virtual school (VS) environments in Alabama. The central research question for this study was: How do virtual school teachers in Alabama describe their experiences of teacher-to-student technology-mediated communication in secondary virtual school environments? Students educated in virtual environments use TMC, so teachers must know what kinds of TMC work best. The problem is that the teacher voice has been ignored in identifying teacher-to-student TMC that is effective in secondary VS environments. Using purposeful sampling of 12 VS teachers in Alabama, this research utilized semi-structured interviews, artifacts, and an asynchronous online focus group to uncover teacher experiences of teacher-to-student interactions in VS environments. In seeking meaning from their experiences, the predominant theme of whatever is best for the students became evident. Four themes developed pertaining to the participants’ experiences: Teacher mindset, teacher presence, integration of technology into instruction, and technology issues.     

Three-feature model to reproduce the topology of citation networks and the effects from authors’ visibility on their h-index

Various factors are believed to govern the selection of references in citation networks, but a precise, quantitative determination of their importance has remained elusive. In this paper, we show that three factors can account for the referencing pattern of citation networks for two topics, namely “graphenes” and “complex networks”, thus allowing one to reproduce the topological features of the networks built with papers being the nodes and the edges established by citations. The most relevant factor was content similarity, while the other two – in-degree (i.e. citation counts) and age of publication – had varying importance depending on the topic studied. This dependence indicates that additional factors could play a role. Indeed, by intuition one should expect the reputation (or visibility) of authors and/or institutions to affect the referencing pattern, and this is only indirectly considered via the in-degree that should correlate with such reputation. Because information on reputation is not readily available, we simulated its effect on artificial citation networks considering two communities with distinct fitness (visibility) parameters. One community was assumed to have twice the fitness value of the other, which amounts to a double probability for a paper being cited. While the h-index for authors in the community with larger fitness evolved with time with slightly higher values than for the control network (no fitness considered), a drastic effect was noted for the community with smaller fitness.     

COLLABORATION FOR A CURRICULUM OF CARING: THE ZEITGEIST IS RIGHT

Recent catastrophic school shootings have drawn worldwide attention to issues of gun control and mental health. In the wake of these tragedies, more and more schools have begun to adopt school‐wide social and emotional learning (SEL) programs. However, we have few examples of what it looks like to integrate SEL skills into content curricula. What's more, teachers and support professionals are ill‐equipped to engage in the collaborative work necessary to effectively integrate the teaching of SEL into academic content. The collaboration described herein highlights an interdisciplinary collaboration among university faculty and graduate students from school psychology and English education to collaboratively design and evaluate standards‐based secondary English curricula that foreground SEL and themes of care.     

Learning to teach teachers

This paper reports on a study of the practices of a cohort of traditionally appointed teacher educators with the responsibility for facilitating teacher learning and learning teaching. The approach used in this investigation involved a practice-to-theory field experience (PTE), a reflective paper analyzing the PTE, and a shared set of readings on pedagogy for facilitating teacher learning and learning teaching with the PTE as context. The participants in this study were 21 students enrolled in an education doctorate program at a Research I university in the Western United States. The findings from the study revealed that the number of years of experience as a teacher educator was not related to competence or effectiveness. Further, it was found that the combined processes of documenting practice, writing a reflective paper, and engaging in focused dialog with peers based on a shared set of readings, and incorporating the PTE as context enabled participants to think critically and co-construct deep knowledge and understanding of the role of the teacher educator and practices for facilitating teacher learning and learning teaching.     

COUNSELING THE ELDERLY: A TRAINING PROGRAM FOR PROFESSIONALS

The present study examined the effectiveness of a training program designed to teach mental health professionals information and skills specific to counseling the elderly client. Twenty‐eight women and four men, ranging in age from 23 to 56, completed the 12‐hour training program. Results indicated that participants showed statistically significant gains on the two major assessment devices after completion of the training program. Concomitantly, job satisfaction and perception of preparedness for their current jobs as counselors to the elderly were affected in a positive direction, providing support for the efficacy of the program. The impact of the training was also sustained at the two‐month follow‐up. Regression analyses revealed that the trainee characteristic that was most predictive of success in the program was that having to do with prior knowledge; those entering the program with a higher level of basic knowledge tended to improve and learn more in training.     

Collaborative Mentorship: A Mentoring Approach to Support and Sustain Teachers for Equity and Diversity

In this article, I propose collaborative mentorship (CM) as a mentoring approach to support and sustain teachers in diversity and equity education. CM is theorized as a mentoring relationship grounded in critical dialog between mentor and mentee. Drawing on research conducted in a culturally, racially, linguistically, and socially diverse secondary school in Southern Ontario, Canada, this article examines tensions teachers experience with equity and diversity and the knowledge base necessary for such a mentoring approach. As the schools become more diverse, it is vital that teachers seek out new approaches that respond to the changing social contexts. The findings of my research have implications for teacher professional development and teacher training in discovering new ways to support in diverse classrooms.
