A Systematic Review of Remote Laboratory Work in Science Education with the Support of Visualizing its Structure through the <Emphasis Type="Italic">HistCite</Emphasis> and <Emphasis Type="Italic">CiteSpace</Emphasis> Software

Laboratory work, particularly the latest remote laboratories (RLs), has been assumed to have a general positive effect on science education because practical work can provide diverse learning experiences and enhance thinking skills suitable for the 21^st century. However, there has not been a synthesis of the science education research to support this assumption. The objective of this study is to systematically review the growth of educational research on laboratory work, particularly in RLs, utilizing a series of review processes with innovative software for visualizing structural relationships. The combined use and support of HistCite and CiteSpace software enabled the visualization of the citation structure and history of articles. The findings revealed that RLs were a state-of-the-art subset of laboratory work and a new way of conducting laboratory work that has gained fairly wide research attention in engineering education over the past two decades. Thus, this innovative literature review process has established a solid background for future research and development efforts on RLs in science education dealing with scientific and engineering practices.     

Managing Element Interactivity in Equation Solving

Between two popular teaching methods (i.e., balance method vs. inverse method) for equation solving, the main difference occurs at the operational line (e.g., +2 on both sides vs. ?2 becomes +2), whereby it alters the state of the equation and yet maintains its equality. Element interactivity occurs on both sides of the equation in the balance method, but only on one side in the case of the inverse method. Thus, the balance method imposes twice as many interacting elements as the inverse method for each operational line. In two experiments, secondary students were randomly assigned to either the balance method or the inverse method to learn how to solve one-step, two-step, and three-or-more-step linear equations. Test results indicated that the interaction between method and type of equation favored the inverse method for equations involving higher element interactivity. Hence, by managing element interactivity, the efficiency of instruction for equation solving can be improved.     

Teachers’ Perceptions of Appraiser–Appraisee Relationships

Teacher appraisal procedures may lead to formative (teacher development and improvement of teaching) and summative (managerial decision) outcomes. Elementary school teachers in Hong Kong (N=527) responded to survey items on formative outcomes, summative outcomes, perceived purposes of appraisal, overall effectiveness of appraisal, and summative purposes such as promotion and dismissal of staff. Principal components analysis and confirmatory factor analysis yielded the two a priori outcome factors, each of which was significantly correlated with perceived overall effectiveness of appraisal. Analysis of variance found that senior teachers appraised by the school principal (SP) perceived that appraisal had formative purposes and this perception was stronger than for those teachers appraised by senior staff (TS). Teachers in the TS group did not perceive the importance of the promotion purpose as did the other groups. Teachers appraised by the principal (TP) perceived that appraisal had dismissal purposes whereas teachers in the TS group did not. Although the three groups did not differ in their perceptions of formative outcomes, summative outcomes, or overall effectiveness of teacher appraisal, the appraiser-appraisee combination did make a significant difference in teacher perceptions of the purposes and appropriateness of the appraisal.     

Development of a computer-assisted cranial nerve simulation from the visible human dataset

Advancements in technology and personal computing have allowed for the development of novel teaching modalities such as online web‐based modules. These modules are currently being incorporated into medical curricula and, in some paradigms, have been shown to be superior to classroom instruction. We believe that these modules have the potential of significantly enriching anatomy education by helping students better appreciate spatial relationships, especially in areas of the body with greater anatomical complexity. Our objective was to develop an online module designed to teach the anatomy and function of the cranial nerves. A three‐dimensional model of the skull, brainstem, and thalamus were reconstructed using data from the Visible Human Project and Amira®. The paths of the cranial nerves were overlaid onto this 3D reconstruction. Videos depicting these paths were then rendered using a “roller coaster‐styled” camera approach. Interactive elements adding textual information and user control were inserted into the video using Adobe Creative Suite® 4, and finally, the module was exported as an Adobe Flash movie to be viewable on Internet browsers. Fourteen Flash‐based modules were created in total. The primary user interface comprises a website encoded in HTML/CSS and contains links to each of the 14 Flash modules as well as a user tutorial.

Contested spaces: trans-inclusive school policies and parental sovereignty in Canada

ABSTRACT

This article analyses five public consultation meetings about revisions to an LGBTQ-related school board policy on unceded Coast Salish territory in Vancouver, British Columbia, Canada. These meetings focused largely on the new provision that students in publicly funded schools be allowed to use the washroom that corresponds with their gender identity. Almost all of the objections to the policy revisions were articulated by parents of non-queer, or not openly queer students. We found that these parental concerns centred around two perennial issues in Canadian educational studies; namely, how schools regulate students’ gender identities and expressions, and the role of the state in publicly funded schooling. We conclude by drawing upon emerging literature on best practices for trans youth in schools to offer alternative visions for how these issues can be better addressed with the public, and parents in particular.     

Higher Education in Hong Kong: the context of and rationale for rapid expansion

Hong Kong is now engaged in implementing a programme designed rapidly to expand its Higher Education sector. This policy will effectively shift the role of higher education away from providing for the needs of a small and elite segment of school leavers to one which provides for a significant proportion of the relevant age cohort.The paper initially identifies the factors which have contributed to the emergence of the new policy. Central amongst these is the impending return of Hong Kong's sovereignty to the PRC in 1997. Subsequently the policy is analysed with reference to the context within which it will be implemented. This includes the shifting demographic structure, the level of emigration and the number of students who study overseas. Finally the paper anticipates the probable impact of the expansion on both higher education itself and on other sectors within the education system.     

Maximum oxygen uptake and body composition of healthy Hong Kong Chinese adult men and women aged 20 - 64 years

The aims of the present study were to assess the maximal oxygen uptake and body composition of adult Chinese men and women, and to determine how these variables relate to age. The cross-sectional sample consisted of 196 men and 221 women aged 20 - 64 years. Maximal oxygen uptake (VO2max) was determined by indirect calorimetry during a maximal exercise test on an electrically braked cycle ergometer. The correlations between VO2max and fat mass were -0.52 in men and -0.58 in women. Linear regression defined the cross-sectional age-related decline in VO2max as 0.35 ml kg(-1) min(-1) year(-1) in men and 0.30 ml kg(-1) min(-1) year(-1) in women. Multiple regression analysis showed that more than 50% of this cross-sectional decline in VO2max was due to fat mass, lean mass, and age. Adding fat mass and lean mass to the multiple regression models reduced the age regression mass from 0.35 to 0.24 ml kg(-1) min(-1) year(-1) in men and from 0.30 to 0.15 ml kg(-1) min(-1) year(-1) in women. We conclude that age, fat mass, and lean mass are independent determinants of maximal oxygen uptake in Chinese adults.
