Are Virtual Labs as Effective as Hands-on Labs for Undergraduate Physics? A Comparative Study at Two Major Universities

Most physics professors would agree that the lab experiences students have in introductory physics are central to the learning of the concepts in the course. It is also true that these physics labs require time and money for upkeep, not to mention the hours spent setting up and taking down labs. Virtual physics lab experiences can provide an alternative or supplement to these traditional hands-on labs. However, physics professors may be very hesitant to give up the hands-on labs, which have been such a central part of their courses, for a more cost and time-saving virtual alternative. Thus, it is important to investigate how the learning from these virtual experiences compares to that acquired through a hands-on experience. This study evaluated a comprehensive set of virtual labs for introductory level college physics courses and compared them to a hands-on physics lab experience. Each of the virtual labs contains everything a student needs to conduct a physics laboratory experiment, including: objectives, background theory, 3D simulation, brief video, data collection tools, pre- and postlab questions, and postlab quiz. This research was conducted with 224 students from two large universities and investigated the learning that occurred with students using the virtual labs either in a lab setting or as a supplement to hands-on labs versus a control group of students using the traditional hands-on labs only. Findings from both university settings showed the virtual labs to be as effective as the traditional hands-on physics labs.     

Academic responding during instruction and reading outcomes for kindergarten students at-risk for reading difficulties

The purpose of this study was to investigate the academic responding of students at-risk for reading difficulties in beginning reading instruction. Opportunities for kindergarten students at-risk for reading difficulties to respond academically during teacher-facilitated reading instruction in the general education classroom were examined in relation to student reading achievement as well as social behaviors. Student academic responding during teacher-facilitated instruction significantly predicted end of year reading achievement. Teacher perceptions of students’ social skills (positive correlation) and problem behaviors (negative correlation) were significantly correlated with academic responding. When academic responding and teacher perceptions of social behaviors were examined together, only teacher perceptions of academic competence and problem behaviors predicted spring outcomes.

One-Stop Shopping: Merging Service Points in a University Library

ABSTRACT

As libraries change to meet the evolving needs of our patrons, including the development of online services, many libraries are considering consolidating physical service points to maximize staff and better serve the in-house patron. This article describes the planning, implementation, and evaluation process involved in merging the circulation and reference desks at the University of New Orleans Library. The cross-training process is described in detail, and benefits as well as problems experienced are outlined. The authors also provide advice for those considering a merge at their library.     

THE AGING POPULATION AS A CHALLENGE FOR THE HELPING PROFESSIONS: SOME OBSERVATIONS ON A RECENT CONTINUING EDUCATION PROGRAM

This article reviews a recent continuing education program held at the University of Western Australia, Perth. The program addressed some of the crucial issues facing professionals in the field of aged services and comprised a one‐day seminar and a series of workshops. It was hosted by the Department of Social Work and Social Administration over a six‐week period and examined a wide range of issues in gerontological social work practice.     

Representations of nature of science in U.S. science standards: A historical account with contemporary implications

This study evaluated the representations of nature of science (NOS) in U.S. state science standards, and examined the changes in these representations from documents advanced in the 1980s through 2016. Drawing from the consensus perspective on NOS and prior studies focusing on the analysis of textual content, documents were inspected for 10 target NOS aspects: the empirical, tentative, inferential, creative, theory-driven, and social NOS, in addition to the myth of “The Scientific Method,” the nature of scientific theories and laws, and the social and cultural embeddedness of science. Ninety-eight state documents from 48 states were analyzed and multiple editions were collected from 34 states. Additionally, relevant materials from the Next Generation Science Standards (NGSS) were assessed for their coverage of the same NOS aspects. Collected materials were scored as whole documents, including over 11,000 pages of text in total, on each target aspect, which reflected the treatment (naïve vs. informed) of NOS in text and the manner of presentation (explicit vs. implicit). Overall, surprisingly, state standards documents have improved very little with respect to their NOS coverage over the last 30 years. NOS standards documents remain silent on a majority of key aspects of NOS, and the number of aspects showing explicit, informed representations has held constant. The NGSS performed well compared to many contemporary documents, but they failed to address all target NOS aspects in a desirable manner. Further analysis raised concerns with the degree that states fully adopt and disseminate standards in manner consistent with the NGSS despite stated intentions, which may negatively impact NOS coverage in instructional resources and classroom enactments. To improve NOS representations in standards, recognizing the role these documents play in shaping instructional materials and teaching in the science classroom, exemplars from analyzed materials were highlighted with informed and explicit representations of multiple aspects.
