Science Laboratory Classroom Environments at Schools and Universities: A Cross‐National Study∗

ABSTRACT

Because already existing classroom environment scales are unsuitable for science laboratory classes, a new instrument was developed and validated in a Class form (student's perceptions of the class as a whole) and a new Personal form (student's perceptions of his/her own role within the class). The instrument was cross‐nationally field tested with 5,447 students in 269 classes in six countries, and cross‐validated with 1,594 students in 92 classes in Australia. Each scale exhibited satisfactory internal consistency reliability, discriminant validity, and factorial validity, and differentiated between the perceptions of students in different classes. Use of the new instrument revealed that: science laboratory classes are dominated by closed‐ended activities; Class form means consistently were more favorable than Personal form means; associations existed between attitudinal outcomes and laboratory environment; and the Class and Personal form each accounted for unique variance in student attitudes.     

Warwick University PGCE Mentoring Scheme

As schools and HEIs have become partners in initial teacher education, the roles of personnel from both institutions have experienced radical change. Whilst the role of the university tutor as a student support and assessor has diminished, the teacher's role has been extended, to that of the student's subject‐specific mentor. Considering the importance of mentorship in the teacher education process and the lack of evidence on mentoring from the student's perspective, the present study sought to expand on current knowledge and increase understanding of the student's perspective through exploration of postgraduate PE and Dance students’ perceptions of the mentor role and the mentorship relationship at the University of Brighton. This study forms part of a larger, collaborative project between the University of Brighton and Liverpool John Moore's University which is investigating the development and impact of School Based Teacher Education Partnerships. In semi‐structured interviews, 25 students were asked to discuss: ideal qualities for mentoring and the student/mentor relationship; the mentor's role and their influence on the student. Students generally valued a supportive, professional relationship with their mentor which allowed mutual input and a mentor who is approachable and has a depth of subject expertise. These findings indicated the need, in the course of future research, to consider interaction and information exchange in the student/mentor relationship and the perceived and actual role which student and mentor play in this relationship.

Of current interest is the postgraduate student's experience of mentoring, which is highlighted and discussed in the present article. The data discussed here derive from work in the project's early stages at the University of Brighton, and the article is the first in a series which will be presented as the project continues. Future publications will discuss investigations which expand on the present findings and which result from either collaborative inquiry between the two institutions or replication studies to enable cross‐comparison between findings.     

Effect of acquisition rates on off‐task behavior of kindergarten students while learning sight words

Assessing a student's acquisition rates (ARs) is a reliable way to determine how many new words should be taught in one lesson without reducing retention. Exceeding a student's AR can result in frustration and problem behaviors. The purpose of this study was to examine the effect of AR on the off‐task behavior of kindergarten students while participating in a commonly used sight‐word instruction video. Participants included 39 kindergarten students whose ARs were assessed before showing the sight‐word video. Behavior was measured as on‐ and off‐task using momentary time‐sampling with 10‐s intervals. Results indicated that students' time off task increased after exceeding their ARs, with a noticeable immediate increase. The implications and limitations of these results are discussed.     

Undergraduate project work: can directed tutor support enhance skills development?

Students' perceptions of their skills development and the overall value of their undergraduate project work were evaluated using data derived from questionnaires. Thirty‐nine students completing their second year of study (i.e. prior to the commencement of project work) and 42 students completing their third‐year project work took part. Thirteen tutors also completed questionnaires. They were asked to give their perceptions as to what skills project students developed and what attributes of project work enhanced both students' personal development and students' assessment grades. Results showed a shift in students' perceptions of the types of skills reinforced, developed and assessed within project work during the course of their third‐year project. Their perceived views did not fully coincide with tutors' perceptions of student skills development, although evaluation of both the assessment and personal importance of particular aspects of project work showed some interesting relationships between students and tutors. The diversity of opinion shown in these results may be due to lack of clarification of assessment criteria rather than a ‘hidden curriculum’. For example, the distinction between presentation of work and scientific writing may not be clear from an initial reading of the criteria. The outcomes of this study, with particular reference to the relationship between scientific writing and thinking, have implications regarding tutor and student discussion, the development of marking criteria and the use of plenary project support sessions.     

Effects of training experienced teachers in the use of the one‐minute preceptor technique in the gross anatomy laboratory

The one‐minute preceptor (OMP) is a time‐efficient, learner‐centered teaching method used in a busy ambulatory care setting. This project evaluated the effects of training experienced anatomy teachers in the use of the OMP in the gross anatomy laboratory on students' perceived learning. Second‐year medical students from a five‐year, undergraduate‐entry, system‐ and problem‐based medical program were divided randomly into two groups of 76 students each. The groups took part in the same gross anatomy laboratory session on different dates, supervised by the same two teachers (both with over 25 years of teaching experience). The teachers attended a workshop on the use of the OMP between the two sessions. Students were given a questionnaire at the end of the two sessions to indicate their agreements to statements regarding their learning experiences. Semistructured interviews were conducted with the two teachers after the second session. Results showed that training experienced anatomy teachers in the use of the OMP did not result in improvement of student learning perception in the gross anatomy laboratory. The experienced teachers have developed their own approaches with elements similar to those in the OMP: being learner centered and adaptable to individual student's needs, providing feedback, and enhancing teacher immediacy. They do not have an explicit structure such as the OMP, and are thus flexible and adaptive. Confining the teachers' teaching behaviors to the OMP structure could limit their performance. Although there are theoretical advantages for novice teachers in adopting the OMP technique, these advantages still need to be supported by further studies.

Facilitating Meta‐learning in Art and Design Education

Art and design programmes are educationally unique in that students themselves play a central role in determining their own learning needs. To be successful in their study, art and design students are required to operate with a high degree of independence and self‐direction. Developing the skills for greater self‐reliance requires students to become aware of their conceptions of the subject of study, and of themselves as learners in a particular learning context. Developing greater self‐awareness as a learner and becoming more independent in one's learning is captured by the concept of meta‐learning. In this article I present an alternative strategy to prevalent diagnostic approaches to assist in developing a student's capacity for meta‐learning in the subject context of art and design. An inquiry cycle was created to provide a structure within which to facilitate generative thinking about learning through engaging with fundamental questions related to the subject of learning (art and design) rather than the learning subject (i.e. the student). This method represents a departure from existing approaches to engaging students in meta‐learning. A pilot study used to trial the effectiveness of this strategy is also presented here. The inquiry map, and the conceptual base upon which it was developed, were found to be useful ways to structure reflective thinking about learning and to assist in developing a student's conception of the subject.     

Exploring an experiential learning project through Kolb's Learning Theory using a qualitative research method

Experiential learning pedagogy is taking a lead in the development of graduate attributes and educational aims as these are of prime importance for society. This paper shows a community service experiential project conducted in China. The project enabled students to serve the affected community in a post-earthquake area by applying their knowledge and skills. This paper documented the students’ learning process from their project goals, pre-trip preparations, work progress, obstacles encountered to the final results and reflections. Using the data gathered from a focus group interview approach, the four components of Kolb's learning cycle, the concrete experience, reflection observation, abstract conceptualisation and active experimentation, have been shown to transform and internalise student's learning experience, achieving a variety of learning outcomes. The author will also explore how this community service type of experiential learning in the engineering discipline allowed students to experience deep learning and develop their graduate attributes.     

School Students' Responses to Architecture:a practical studio project

This paper focuses on a built environment project with a mixed ability group of learners from year seven attending Deacon's School in Peterborough, England. The School caters for students aged between eleven and eighteen, from a wide range of ethnic and cultural backgrounds (including a substantial minority from the Indian Sub‐Continent); it is an active participant within the University of Cambridge Post Graduate Certificate in Education partnership and is a ‘beacon school’. In practical studio terms, the project was concerned with school students making ‘pop‐up cards’ based on first hand observation of local architecture under the guidance of the Head of Art. [1] The focus for students' learning was on their critical responses to their built environment, in and around the City of Peterborough. In particular, students were encouraged to make full use of their sketchbooks and to engage in active oral work. The approach taken builds upon that advocated by Wolff and Geahigan [2] by emphasising the relationship between students' personal engagement with art and design and their personal response to it through their own art; students were encouraged to learn about art and design objects through the process of reacting, researching, responding and reflecting.

Do Research Findings Apply to My Students? Examining Study Samples and Sampling

Special educators are urged to use research findings to inform their instruction in order to improve student outcomes. However, it can be difficult to tell whether and how research findings apply to one's own students. In this article, we discuss how special educators can consider the samples and the sampling methods in studies to examine the relevance of research findings for their students. We describe two approaches for examining the degree to which research findings apply to one's students—the classical generalization model and the case‐to‐case transfer model. We also note additional factors and caveats to consider when evaluating the applicability of research findings, examine the implications of samples and sampling in two research studies, and provide a take‐away message that educators should determine the relevance of research findings for their own students by examining studies’ samples and the sampling methods.     

An investigation of Zimbabwe high school chemistry students' laboratory work–based images of the nature of science

This study investigates the proximal and distal images of the nature of science (NOS) that A‐level students develop from their participation in chemistry laboratory work. We also explored the nature of the interactions among the students' proximal and distal images of the NOS and students' participation in laboratory work. Students' views of the NOS and the nature of their chemistry laboratory work were elicited through students' responses to an open‐ended questionnaire and semistructured interviews. The results suggest that students build some understandings of the NOS from their participation in laboratory work. Students' proximal NOS understandings appear to build into and interact with their understandings of the nature and practice of professional science. This interaction appears to be mediated by the nature of instruction. It is posited that each student's conceptual ecological system is replete with interactions, which govern attenuation of proximal understandings into distal images. Methodologically, the study illustrates how students' laboratory work–based proximal and distal images of the NOS can be identified and extracted through analyzing and interpreting their responses to protocols. Implications for A‐level Chemistry instruction and curriculum development are raised. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 127–149, 2006     

Pedagogical Thinking in a Student's Mind: A conceptual clarification on the basis of self‐determination and volition theories

This article suggests that educational psychology should pay more attention to the role of the curriculum when the optimal motivation to learn in school is considered. The curriculum frames the teaching‐studying‐learning process in school. This fact has several implications on the motivation to learn in school. After the child starts school, his or her motivation to learn seems to change from an intrinsic motivation to an extrinsic motivation. To develop pedagogical thinking in a student's mind means that the student must become acquainted with the aims and goals of the curriculum, assimilate them into his or her integrated sense of self and, thus, fully accept them as their own. If this succeeds, it will have positive effects on the student's motivation at school and especially on the motivation to study and learn. The concept of pedagogical thinking in a student's mind is analogous to the concept of teacher's pedagogical thinking. Based on previous studies, this article provides an example of how joint‐planning can offer a learning environment that promotes students' pedagogical thinking and the internalisation of the aims and goals of the curriculum in school. This article calls for new theoretical syntheses and research programmes that better take into account the normative nature of learning and teaching in school.     

A Comparison of the Degree of Student Satisfaction using a Simulation or a Traditional Wet Lab to Teach Physical Properties of Ice

It is often difficult to offer food chemistry students traditional, hands‐on laboratory experiences due to lack of funds for equipment, insufficient laboratory space, or the nature of distance education. A traditional wet laboratory exercise was developed to demonstrate the effects of the physical properties of ice formation when making high‐quality sorbets, varying the amounts of sugar, water, and stabilizer. This wet lab was compared to a simulated, detective‐based crime scene investigation (CSI) of why a famous food scientist's sorbet had become a “stiff.” Forty‐six food chemistry students were randomly assigned to groups, completing either the traditional wet lab or the simulated lab 1st before completing the 2nd type of laboratory. While there were preferences for one lab over another, there were no differences in the learning outcomes between the 2 laboratory formats. Students who preferred the simulated lab felt they could move at their own pace and were able to stop and review the simulation to understand the concepts more clearly. Traditional wet lab proponents liked working in groups and having immediate access to instructors. From the initial evaluation it appears that simulations could be used as replacements for hands‐on laboratory experiences or could serve as effective introductions to laboratory principles and concepts, resulting in increased student learning.     

AN ANALYSIS OF TEACHING AND THE RELATIONSHIP BETWEEN UNIVERSITY TEACHERS AND STUDENTS

As a principal task of higher education in the German Democratic Republic is to create the conditions by which it will have a major impact upon development, a major aspect of these conditions refers to the relationship between university teachers and students. The totality of this relationship can be broken down into relationships of partnership, of authority, and of work. The third of these relationships, particularly collaboration in research projects, creates the best links between teachers and students and enables teachers to gain the fullest knowledge of their students and to have the most fruitful influence over them. The validity of this assertion has been corroborated by the results of the author's investigations of the stimulating and orientational effects of communicative and cooperative relations at Central Exhibitions of Achievements of Students and Young Scientists in the German Democratic Republic. In order to obtain the best pedagogical results through collaborative work, the teacher must understand and add to the student's motivations and be prepared to stimulate the learning process through constant evaluation of both specific achievements and of the development of the student's personality resulting from work on the project. The latter evaluation criterion is in turn best measured by the assessment of results achieved against objectives and by an analysis of the environment of the study process. As individual teachers can only know students in specific courses, the position of “seminar group advisor” has been created in the GDR to be filled by young academics who are assigned to groups of students from their matriculation to their graduation.     

A learning model for enhancing the student's control in educational process using Web 2.0 personal learning environments

In recent educational literature, it has been observed that improving student's control has the potential of increasing his or her feeling of ownership, personal agency and activeness as means to maximize his or her educational achievement. While the main conceived goal for personal learning environments (PLEs) is to increase student's control by taking advantage of Web 2.0 tools and technologies, there is not a robust learning model available to achieve it. This contribution focuses on proposing a learning model built upon self‐regulated learning and student's control theories and concepts, and supported by the learning affordances of Web 2.0 tools and technologies for enhancing student's control by developing and applying Web 2.0 PLEs.     

Controlling response shift bias: the use of the retrospective pre‐test design in the evaluation of a master's programme

Traditionally the measures used to evaluate the impact of an educational programme on student outcomes and the extent to which students change is a comparison of the student's pre‐test scores with his/her post‐test scores. However, this method of evaluating change may be problematic due to the confounding factor of response shift bias when student self‐reports of change are used. Response shift bias occurs when the student's internal frame of reference of the construct being measured, for example research ability or critical thinking, changes between the pre‐test and the post‐test due to the influence of the educational programme. To control for response shift bias the retrospective pre‐test method was used to evaluate the outcomes achieved from students completing a research module at master's level. The retrospective pre‐test method differs from the traditional pre‐test–post‐test design in that both post‐test and pre‐test perceptions of respondents are collected at the same time. The findings indicated that response shift bias was evident in that the programme had significantly greater impact on outcomes than identified using the traditional pre‐test–post‐test design leading to the conclusion that students may overestimate their ability at the commencement of an educational programme. The retrospective pre‐test design is not a replacement for the traditional pre‐test–post‐test measures but may be a useful adjunct in the evaluation of the impact of educational programmes on student outcomes.     

Project work in the graduate classroom: Teachers as students apply skills beyond the classroom

Abstract

Through the use of a long‐term project in a graduate teacher education course on the importance of play, students learned skills beyond those usually required in a graduate classroom. Students used their understanding and knowledge of play, constructive practice, and project work to develop a family play day at the university lab school. As part of the project, students helped to develop a play‐style instrument that served as a self‐study for their own classrooms as they observed the play among their own students. The project culminated with the students hosting the families of the lab school at a fun day and preparing a brochure that gave families information about the importance of play.     

Student‐directed learning strategies to promote the progress of students with intellectual disability in inclusive classrooms

Student‐directed learning strategies involve teaching students to modify and regulate their own behaviour. Teaching students to self‐regulate behaviour has been identified as one means of promoting self‐determination, and promoting and enhancing self‐determination has become a valued outcome internationally. In addition, however, student‐directed learning strategies could prove important for including students with disabilities in general education classrooms by reducing the student's dependency upon others in the classroom setting. Four students with intellectual disability were supported to select an educational goal on which they wanted to work and were taught to self‐monitor their progress toward that goal in general education classrooms. Their progress toward the goal was evaluated through data collection activities and by using the Goal Attainment Scaling process. In general, students achieved their self‐selected goals. The potential contribution of student‐directed learning strategies to inclusion and promoting self‐determination are discussed.     

Hydrodistillation and antimicrobial properties of lemongrass oil (Cymbopogon citratus,Stapf): An undergraduate laboratory exercise bridging chemistry and microbiology

A traditional classroom usually focuses on concepts from a specific discipline. However, solving complex real‐world problems requires integration and application of knowledge from various fields. Here, we describe a 4‐hr undergraduate‐level laboratory exercise that utilizes concepts of extraction and biological property, bridging between chemistry and microbiology courses. In the first half of this exercise, students performed hydrodistillation to extract essential oil from a locally available herb, lemongrass (Cymbopogon citratus, Stapf). In the second half, students investigated the potential antimicrobial activity of the extracted oil against various microorganisms using the Kirby–Bauer disk diffusion method. Students also developed their own experimental questions based on the extracted oil and the antimicrobial testing technique. Self‐assessment questionnaire shows students’ appreciation of the experiments and substantial learning gains in the extraction process, properties of the extracts, and antimicrobial activity testing. This laboratory exercise prompts students to formulate their own experimental questions and engages students in interdisciplinary experimentation.     

Postgraduate Research: Some Changing Personal Constructs in Higher Education

This paper discusses how computer programs, such as FOCUS and SOCIOGRIDS, can aid students and staff in learning about their own formerly tacit perceptions of research effectiveness. The programs are designed to elicit and analyse one's own construct system and theory of, for example, learning, teaching, or research. The computer printout can be used to facilitate “learning conversations” either with oneself or with others. A greater awareness and understanding of one's own theory and that of expert others can lead to improved learning, teaching or research.

Kelly's (1955) theory of personal constructs and its repertory grid technology made it possible for the present study to demonstrate and measure both how the construing of a group of continuing postgraduate students changed over the three‐months period of their professional preparation as researchers and how it differed from that of four experienced staff researchers. This study shows how computers can help promote greater personal control over the construction and negotiation of meaning in higher education.     

Development and evaluation of an interactive electronic laboratory manual for cooperative learning of medical histology

This article describes the development of an interactive computer‐based laboratory manual, created to facilitate the teaching and learning of medical histology. The overarching goal of developing the manual is to facilitate self‐directed group interactivities that actively engage students during laboratory sessions. The design of the manual includes guided instruction for students to navigate virtual slides, exercises for students to monitor learning, and cases to provide clinical relevance. At the end of the laboratory activities, student groups can generate a laboratory report that may be used to provide formative feedback. The instructional value of the manual was evaluated by a questionnaire containing both closed‐ended and open‐ended items. Closed‐ended items using a five‐point Likert‐scale assessed the format and navigation, instructional contents, group process, and learning process. Open‐ended items assessed student's perception on the effectiveness of the manual in facilitating their learning. After implementation for two consecutive years, student evaluation of the manual was highly positive and indicated that it facilitated their learning by reinforcing and clarifying classroom sessions, improved their understanding, facilitated active and cooperative learning, and supported self‐monitoring of their learning.
