Enhancing the Student Experiment Experience: Visible Scientific Inquiry Through a Virtual Chemistry Laboratory

Practical work is often noted as a core reason many students take on science in secondary schools (high schools). However, there are inherent difficulties associated with classroom practical work that militate against scientific inquiry, an approach espoused by many science educators. The use of interactive simulations to facilitate student inquiry has emerged as a complement to practical work. This study presents case studies of four science teachers using a virtual chemistry laboratory (VCL) with their students in an explicitly guided inquiry manner. Research tools included the use of the Inquiry Science Implementation Scale in a ‘talk-aloud’ manner, Reformed Teaching Observation Protocol for video observations, and teacher interviews. The findings suggest key aspects of practical work that hinder teachers in adequately supporting inquiry and highlight where a VCL can overcome many of these difficulties. The findings also indicate considerations in using the VCL in its own right.

Developing the characteristic spirit of publicly managed schools in a more secular and pluralist Ireland

This discussion paper considers the identification and definition of the ‘characteristic spirit’ of publicly managed schools in the Republic of Ireland. Some international approaches to values in publicly funded schools are introduced along with relevant contextual aspects of Irish education including the cultural diversity and secularisation of modern Irish society. The Irish Education Act (1998) gives ultimate responsibility for school values and ‘characteristic spirit’ to the school ‘patron’, a role legally separate from that of school ownership and school management. The underlying values of privately managed faith-based schools are well established. However, the ‘characteristic spirit’ of publicly managed Education and Training Board schools remains largely undeveloped. Appropriate responses to this challenge are identified and discussed.     

SEEK Web tutor: fostering a critical stance while exploring the causes of volcanic eruption

We investigated the impact of a Web tutor on college students’ critical stance and learning while exploring Web pages on science. Critical stance is an aspect of self-regulated learning that emphasizes the need to evaluate the truth and relevance of information as the learner engages in systematic inquiry to answer challenging questions. The Web tutor is called SEEK, an acronym for Source, Evidence, Explanation, and Knowledge. The SEEK Tutor was designed to promote a critical stance through several facilities in a computer environment: spoken hints on a mock Google™ search page, on-line ratings on the reliability of particular Web sites, and a structured note-taking facility that prompted them to reflect on the quality of particular Web sites. We conducted two experiments that trained students how to take a critical stance and that tracked their behavior while exploring Web pages on plate tectonics to research the causes of the volcanic eruption of Mt. St. Helens. The SEEK Tutor did improve critical stance, as manifested in essays on the causes of the volcanic eruption, and did yield learning gains for some categories of information (compared with comparison conditions). However, many measures were unaffected by either the presence of the SEEK Tutor or by prior training on critical stance. We anticipate that robust improvements on critical stance and learning will require more training and/or some expert feedback and interactive scaffolding of critical stance in the context of specific examples. This work was conducted while Tenaha O’Reilly was a postdoctoral fellow at the University of Memphis.     

Cultivating minority scientists: Undergraduate research increases self‐efficacy and career ambitions for underrepresented students in STEM

In this study, Social Cognitive Career Theory (SCCT) is used to explore changes in the career intentions of students in an undergraduate research experience (URE) program at a large public minority‐serving college. Our URE model addresses the challenges of establishing an undergraduate research program within an urban, commuter, underfunded, Minority‐Serving Institution (MSI). However, our model reaches beyond a focus on retention and remediation toward scholarly contributions and shifted career aspirations. From a student's first days at the College to beyond their graduation, we have encouraged them to explore their own potential as scientists in a coordinated, sequential, and self‐reflective process. As a result, while the program's graduates have traditionally pursued entry‐level STEM jobs, graduates participating in mentored research are increasingly focused on professional and academic STEM career tracks involving post‐graduate study. In addition to providing an increasingly expected experience and building students’ skills, participation in undergraduate research is seen to have a transformative effect on career ambitions for many students at MSIs. While undergraduate research is often thought of in context of majority‐serving institutions, we propose that it serves as a powerful equalizer at MSIs. Building on the institutional characteristics that drive diversity, our students produce scholarly work and pursue graduate degrees, in order to address the long‐standing under‐representation of minorities in the sciences. © 2016 Wiley Periodicals, Inc.

How Individual Differences Interact With Task Demands in Text Processing

Reading is affected by both situational requirements and one’s cognitive skills. The current study investigated how individual differences interacted with task requirements to determine reading behavior and outcome. We recorded the eye movements of college students, who differed in reading efficiency, while they completed a multiple-choice (MC) comprehension test in two within-subject conditions: one in which they read passages and answered MC questions as in a typical reading test and one in which they wrote a summary before answering the MC questions. We found students spent longer time reading the text in the summary-writing condition, resulting in a benefit in the time they spent when answering MC questions. This time benefit was larger for students who had relatively low reading efficiency. These results demonstrated that both task requirements and individual differences can interact to affect reading behavior and performance. Implications for reading practice and assessment are discussed.     

The determinants of undergraduate degree performance: How important is gender?

This study uses data drawn from three recent cohorts of undergraduates at the University of Sussex to investigate the key determinants of degree performance. The primary theme of the study is an examination of the gender dimension to degree performance. The average ‘good’ degree rate for female students was found to be superior to the male rate. The modest raw gender differential in first class degree rates favoured women but was found to be attributable to their better endowments, particularly pre-entry qualifications. The largest differential favouring women was in the II:i classification, where almost all of the difference was attributable to differentials in coefficient treatment rather than endowments (or characteristics). The analysis undertaken also allowed the investigation of a number of sub-themes relating to the effects on degree performance of, inter alia, pre-entry qualifications, ethnicity, socio-economic background and health disability. The largest effects were reserved for the role of pre-entry qualifications with more modest effects detected for ethnicity and socio-economic background.     

The role of a short post-lunch nap in improving cognitive, motor, and sprint performance in participants with partial sleep deprivation

The aim of this study was to determine the effects of a post-lunch nap on subjective alertness and performance following partial sleep loss. Ten healthy males (mean age 23.3 years, s = 3.4) either napped or sat quietly from 13:00 to 13:30 h after a night of shortened sleep (sleep 23:00-03:00 h only). Thirty minutes after the afternoon nap or control (no-nap) condition, alertness, short-term memory, intra-aural temperature, heart rate, choice reaction time, grip strength, and times for 2-m and 20-m sprints were recorded. The afternoon nap lowered heart rate and intra-aural temperature. Alertness, sleepiness, short-term memory, and accuracy at the 8-choice reaction time test were improved by napping (P < 0.05), but mean reaction times and grip strength were not affected (P > 0.05). Sprint times were improved. Mean time for the 2-m sprints fell from 1.060 s (s(x) = 0.018) to 1.019 s (s(x) = 0.019) (P = 0.031 paired t-test); mean time for the 20-m sprints fell from 3.971 s (s(x) = 0.054) to 3.878 s (s(x) = 0.047) (P = 0.013). These results indicate that a post-lunch nap improves alertness and aspects of mental and physical performance following partial sleep loss, and have implications for athletes with restricted sleep during training or before competition.     

School psychology: The continuing search

This article describes the development of school psychology as a continuing search for identity and professional recognition. This search has led it to identity primarily with psychology at the expense of involvement and concern with the broad issues of educational development. Internal differences have exacerbated school psychology's difficulty in maturing. A suggestion for increased emphasis on learning and a decreased emphasis on mental health issues is offered.
