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.     

THE IMPACT OF A GERONTOLOGICAL INTERVENTION ON OSTEOPATHIC MEDICAL STUDENTS

In order to evaluate the impact of adding a brief unit on aging to the first‐year curriculum of a school of osteopathic medicine a quasiexperimental design was employed. The educational experience involved three hours of classroom material, a visit to a nursing home, and a visit to a congregate housing facility for the well elderly. Over one semester the entire first‐year class was scheduled for the program. Analysis of pretest and posttest data revealed a mild but significant improvement in knowledge and attitudes with respect to the elderly. Subjective responses to the program were very positive.     

LITERACY AND ELDERS: WHAT WE KNOW AND WHAT WE NEED TO KNOW

Little research has been done on the literacy needs and interests of elders. Consequently, many programs of literacy training for elders are based upon inadequate and inaccurate information. The authors review recent literature about literacy and the aged and offer some suggestions for future investigations. They maintain that there is a need for empirical research into the perceptions of reading and writing held by the elderly themselves. Specifically, this research should: (1) assess the reading/writing needs and interests of the elderly; and (2) examine what effect societal expectations of the elderly have on their reading/writing behavior and interests.     

The Destination of Three Paths: Improved Student,Faculty and Staff,and System Learning

Piecemeal change to improve schooling is an approach that at its worst does more harm than good, and at its best is limited to creating pockets of good within school districts. When it comes to improving schooling in a district, however, creating pockets of good isn't good enough. Whole school systems need to be improved.

This article focuses on helping educators learn how to transform entire school systems to create unparalleled opportunities to improve student, faculty and staff, and system learning, and presents a set of principles to help change leaders in school systems navigate large-scale, district-wide change to create these multiple learning opportunities.     

Birthday effects and preschool attendance

Young-for-grade students have been shown to receive lower grades and have a higher likelihood of retention compared to their oldest peers upon kindergarten entry. Our study of 1474 economically disadvantaged first-time kindergarteners investigates if preschool attendance may ameliorate some of the risks potentially associated with being young-for-grade. Using the state-mandated age cutoff date, we establish four groups of students based on age (oldest/youngest in the cohort) and preschool experience (attended preschool/did not attend preschool) and use multilevel linear and logistic regression models in analyzing early literacy scores as well as the likelihood of being retained. Our findings show that while preschool attendance is associated with higher emergent literacy performance, young students still experience higher retention risks compared to their older peers, regardless of preschool attendance and controlling for end-of-year literacy scores.     

Sample Plan for a Survey of Higher Education Enrollment

Despite marked changes in the composition of the population of higher education over the past 20 years, few researchers have tested hypotheses pertaining to predictors of turnover among nontraditional college students. In the present study, we controlled several variables and tested to see whether credit load moderates the effects of intent on turnover at a community college. The results of a stepwise logistic regression model generated from data collected during the spring and fall of 1987 indicated a significant (p < .01) joint effect of credit load and intent. As predicted, intent was more strongly related to turnover among students carrying 13 or more credit hours as compared with students carrying 1–6 and 7–12 credit hours.     

Organizational Chunking and Postquestions in Facilitating Student Ability to Profit from Visualized Instruction

This experiment was designed to examine the instructional effectiveness and efficiency of organizational chunking and batched postquestions within the framework of an information-processing approach to learning and memory. The coding processes utilized by the content organization employed both encoding and retrieval aids to facilitate the acquisition, retention, and retrieval of the information to be learned. Major findings indicate that the chunked treatment resulted in a more efficient learning strategy than the conventional treatment; however, the chunked and conventional treatment, as different encoding strategies, did not produce significant differences in achievement on the performance task. Additionally, students receiving the intervening postquestion strategy took significantly less time in completing the performance measure than did those students who received the non-intervening postquestion treatment.     

INSTRUMENTS AND ENDS IN SPIRITUAL WORLD CONQUEST∗

It is the conviction of the editor that there is a theological basis for a theory of Christian education. In some writings, this theological basis may be hidden or be an aspect of which one is not conscious. But today, as theological reformulations continue to challenge us, theories of Christian education also have undergone certain changes. The emphasis on kerygma among both Catholic and Protestant educators is an illustration of this

As a result of this concern, the editor wrote a number of people asking their cooperation in a brief symposium. The letter and the replies follow     

THE RELATIONSHIP BETWEEN BIBLE READING AND ATTITUDE TOWARD SUBSTANCE USE AMONG 13-15 YEAR OLDS

The relationship between Bible reading and attitude toward drug use is examined among a sample of 25,888 teenagers, 13-15 year olds, throughout England and Wales. Information about sex, age, personality, belief in God, and church attendance was also considered. The conclusion is that Bible reading makes a small but significant contribution to promoting a negative attitude toward drug use among this age group.
