Sensing the Impact of Elementary School Science Reform: A Study of Stakeholder Perceptions of Implementation,Constructivist Strategies,and School–Home Collaboration

This case study of a midwestern school districts reform effort explored the treatment fidelity of the Science: Parents, Activities, and Literature (Science PALs) project. Data were collected from the perspectives of three stakeholders: students, school district, and parents. Students and school district supervisors perceptions indicated that teachers were implementing predicted curricular and instructional features promoted by the Science PALs project. Students perceptions of their current teachers classroom performance did not parallel the supervisors perceptions of the teachers implementation. Parents perceptions and comments indicated a high level of satisfaction with the implemented features. Collectively, the three perspectives suggest that the Science PALs project was successful in changing the classroom practices of K–6 teachers involved in the professional development. The results of this study appear to support the findings of other recent studies that indicate the need for extended professional development and support to fully implement changes in elementary school science instruction.     

The impact of scienceware and foundations on students' attitudes towards science and science classes

In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about using information, drawing conclusions, and thinking about problems, implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems.     

Putting Thought in Accordance with Things: The Demise of Animal-Based Analogies for Plant Functions

Scientists' attempts to understand plant functions by ascribing animal functions to plants – the analogist tradition, derived from Aristotle – began to be superseded in Europe by an experimentalist tradition in the seventeenth century. In classrooms today, science students learning about plant functions (exemplified here by the topic of transpiration) face a parallel dilemma: the pitching of their own habitual mental processes of analogy building (enhanced by the suggestive morphology of plants)and the persuasiveness of everyday language (for example, about plants and water)against the new experimental evidence presented by the teacher. In the case oftranspiration, six practical suggestions whereby teachers can support students in thisstruggle to put their thoughts (especially everyday mental models) in accordance withthings (classroom experimental evidence) are advanced. The wider implications forhow we teach about Living Things, and how we view the status of analogies in sciencegenerally, are discussed.     

Physical and Psychosocial Environments Associated with Networked Classrooms

This article reports a study of the learning environments in computer networked classrooms. The study is unique in that it involved an evaluation of both the physical and psychosocial classroom environments in these computerised settings through the use of a combination of questionnaires and ergonomic evaluations. The study involved administering a student questionnaire designed to assess aspects of the psychosocial learning environment in these settings, and relating these factors to students satisfaction and to important aspects of the physical learning environment. The sample consisted of 1404 students in 81 classes in Australia and Canada. A questionnaire assessing five aspects of psychosocial environment exhibited good factorial validity and internal consistency reliability. When satisfaction was used as a dependent variable, classroom psychosocial environment (especially autonomy/independence and task orientation) was significantly and directly associated with students satisfaction with their learning. In contrast, no direct associations were found between student satisfaction and measures of the physical classroom environment, such as the workspace and visual environments. However statistically significant associations emerged between physical and psychosocial learning environment variables in classrooms using new information technologies. These associations suggest a model of educational productivity for learning environments in technology-rich classrooms. Qualitative case studies provided more detailed information about selected classrooms.     

Towards an electronic independent learning environment for statistics in higher education

This study focuses on the feasibility of implementing independent learning in a traditional university and the feasibility of providing this independent learning by means of an electronic interactive learning environment. The target group contained students enrolled in an applied statistics course at the Department of Psychology and Educational Sciences at the University of Gent (RUG). Three experimental variables were designed: learning environment, delivery and support. This created five different learning conditions to which subjects were assigned at random. The present study gives empirical evidence that an electronic-based independent learning environment with discernible support devices can take its place in a traditional university setting. Our results indicate that the cognitive outcomes of students' learning in a computer-based environment are neither fostered nor hindered by attitudes towards computers. The merely cognitive aspect of attitude towards computers, i.e., interest in learning about computers, affects the perception of structure in the materials; more interested students have a better perception of structure. Students with better prior knowledge and having fewer problems with statistics have a better perception of the learning access to the contents. In order to construct electronic learning environments, further investigation is needed into student characteristics interacting with learning environment characteristics, and this is currently in progress by our group.     

Integrating Curriculum,Instruction, and Assessment in Project-Based Instruction: A Case Study of an Experienced Teacher

This case study of a teacher who engaged his students in inquiry within a technologically rich classroom was conducted over 5 weeks, including 15 regularly scheduled classes. Data include extensive teacher interviews, e-mail, and artifacts such as class notes, curriculum guides, and handouts. A retrospective analysis methodology was utilized to address what Barron et al. (1998), called the major hurdles in implementing project-based curricula: the simultaneous changes in curriculum, instruction, and assessment practices. In addition, a framework developed by the National Research Councils How People Learn was employed to provide detail on the nature of knowledge, learner, assessment, and community centeredness of the project-based unit. Finally, the classroom environment created during a unit of astronomy was analyzed and five principles emerged: the sense of a project, the development of independent individuals, creation of a global community of learners, a cyclic nature of instruction emphasizing conceptual and procedural understanding, and the utilization of distributedexpertise.     

An Investigation of Science Teaching Practices in Indonesian Rural Secondary Schools

This study reports on teaching practices in science classrooms of Indonesian lower secondary schools in rural areas. Using six schools from three districts in the province of Kalimantan Selatan as the sample, this study found that most teaching practices in science classrooms in rural schools were teacher-centred with students copying notes. However, the study also found unique teaching practices of an exemplary science teacher whose teaching style can be described as both student-centred and teacher-centred, with students encouraged to be active learners. Four features of exemplary teaching practices were identified: The teacher managed the classroom effectively; used a variety of questioning techniques; employed various teaching approaches instead of traditional methods; and created a favourable learning environment. Data from classroom observations, interviews with teachers, and students responses to a questionnaire were used to compare the exemplary teacher and his colleagues. This study identified internal factors that may affect teaching practices such as a teachers content knowledge and beliefs about teaching. Compared to the other teachers, the exemplary teacher possessed more content knowledge and had a relatively stronger belief in his ability to teach.     

The Total Quality Initiative at South Bank University

The total quality initiative covers all aspects of the University's academic and support services, but only one of a number of different programmes is discussed in detail, the formulation of quality service agreements. The paper outlines both the theoretical basis and the practical implementation of the approach. Another programme, quality in teaching and learning, is also briefly outlined.The systematic examination and articulation of customer/supplier relationships lies at the core of South Bank's total quality approach, with quality being customer rather than system driven. The concept of the quality chain is developed to stress and demonstrate the interdependence of all staff in providing a high quality service to students.The customer/supplier relationship is founded on three aspects of quality-characteristics, standards and measurement of performance, all of which are dealt with in some detail.Thirty-two Customer/Supplier Working Groups are charged with the task of establishing detailed quality service agreements between academic schools and support departments the internal customers and suppliers, and between the schools as suppliers and their students (and other clients) as external customers.     

Teachers’ Organization of Participation Structures for Teaching Science with Computer Technology

This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher–students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants’ instruction with computer technology was (Teacher) initiation–(Student and Teacher) response sequences–(Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers’ learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers’ own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.     

Collaborative learning processes associated with high and low conceptual progress

Computer-Supported Intentional Learning Environments (CSILE) is a database system in which learners collaboratively construct the knowledge represented in the database. This study examined how students in a grade 5–6 classroom built their classroom database on a science topic, electricity, and differences in activities between high-and low-conceptual-progress students. This categorization of students was based on the amount of progress in understanding exhibited over the course of work on the electricity unit, and was not significantly related to standardized achievement test performance. As an analytic tool, Activity Theory, as explicated by Leontiev (1981) was used to describe students' activities mediated by the computer system. Two different levels of student activities were examined: (1) cognitive actions, in which students intentionally pursued cognitive goals; and (2) computer operations, used to attain these goals. In addition, two different psychological planes of collaborative work were considered: the solo pane, in which students mainly focus on their own inquiries, and the joint plane, in which they focus on improvement of the classroom knowledge as a whole. Comparisons of activities between high-and low-conceptual-progress students showed: (1) that high-conceptual-progress students were more concerned with constructing their knowledge centered around problems, whereas low-conceptual-progress students were more involved in accumulating referent-based knowledge; (2) that high-conceptual-progress students were significantly more likely to construct their knowledge by involving in interactive information flow between problem-based and referent-based knowledge; and (3) that high-conceptual-progress students more frequently used the graphics medium in the database to represent problem-based knowledge.     

Teaching Linear Functions in Context with Graphics Calculators: Students’ Responses and the Impact of the Approach on Their Use of Algebraic Symbols

This study analyses some of the consequences of adopting a functional/modelling approach to the teaching of algebra. The teaching of one class of 17 students was observed over five weeks, with 15 students undertaking both pre- and post-tests and 6 students and the teacher being interviewed individually. Use of graphics calculators made the predominantly graphical approach feasible. Students made considerable progress in describing linear relationships algebraically. They commented favourably on several aspects of learning concepts through problems in real contexts and were able to set up equations to solve contextualised problems. Three features of the program exerted a triple influence on students use and understanding of algebraic symbols. Students concern to express features of the context was evident in some responses, as was the influence of particular contexts selected. Use of graphics calculators affected some students choice of letters. The functional approach was evident in the meanings ascribed to letters and rules. Students were very positively disposed to the calculators, and interesting differences were observed between the confidence with which they asked questions about the technology and the diffidence with which they asked mathematical questions.

Confidence is Everything” – Perspectives of Teachers and Students on Learning Mathematics

This paper problematises confidence as a frequently used explanation for performance in the mathematics classroom. I report on an interview-based study of how some English Advanced level (16+) students who have chosen to study mathematics, and their teachers, speak about confidence with respect to the learning of mathematics. I outline what constitutes confident learners for these teachers and, differently, for their students and what the students feel teachers could do to improve the students confident state. I discuss the implications of this for the education of prospective teachers of mathematics.     

The interrelations between diagrammatic representations and verbal explanations in learning from social science texts

This study examined the instructional effectiveness of abstract diagrams and verbal explanations in learning from social science texts, which contained multi-thematic information and were new to the students. Two texts of about 4,000 words each were examined. Each text appeared in four versions, in which the verbal and schematic representations were manipulated. Unlike previous studies conducted on diagrams and other visual devices that are isolated from the broad research on verbal processing, this study incorporates the investigation of the diagrams' functional utility into the broad context of cognitive elaborations applied to text comprehension. 416 students of Everyman's University, the Open University of Israel, participated in the study. The main results indicate that: an explained diagram is more effective than an unexplained one in complex explanations; a diagram, in general, is more effective than a verbal explanation in representing sequential and hierarchical relations; a diagram has a significant effect on active recollection and passive retention; the mode of the text's design and presentation is more influential than the initial verbal and visual aptitudes; and finally, there are no differences between male and female in processing verbal and diagrammatic representations.     

Collaborative action research on the learning and teaching of algebra: a story of one mathematics teacher's development

This paper presents the story of a mathematics teacher's transformation that resulted from her engagement in collaborative action research. The collaborative research, conducted by a university mathematics educator and an eighth-grade mathematics teacher (Marylin), centered on investigating the outcomes of implementing a Hands-On Equations approach to teaching algebra. This algebraic study, which is briefly reported herein, serves as a vehicle for examining the questions, reflections, and changes brought forth by Marylin throughout the collaborative process. Thus, the project of investigating the teaching and learning of algebra can be viewed as the sub-study within the broader study of the effects of collaborative action research on the mathematics teacher involved in the investigation. Within this paper, issues related to the broader study of collaborative action research in the mathematics classroom, that are connected to Marylin's transformation, are discussed. These issues include the characterization of and goals for collaborative action research as well as the challenges for collaborative action research in mathematics classrooms.This revised version was published online in September 2005 with corrections to the Cover Date.     

Career Development and the Needs of Young College-Educated Females in Taiwan

This interpretive study examined the lived experiences of young college-educated Taiwanese women employed as clerical workers. Using hermeneutic phenomenology as the research methodology, the study explored the meanings of the participants lived experiences. Systematic text analysis of the data revealed various experiences and expectations. Experience themes identified in the study were: (a) bored and busy; and (b) disrespected and mistrusted. Major expectation themes revealed are: (a) career dreams and aspirations; and (b) desire for meaningful work. The study emphasised the importance of career development education in young Taiwanese women. The experiences of Taiwanese female clerical workers as recorded in the study reflected a need for career development, which might provide insightful information for career development scholars and practitioners.     

Formative Peer Review of Teaching: Attitudes of Faculty at Liberal Arts Colleges Toward Colleague Assessment

Nearly all students of faculty evaluation agree that peer review should be part of a comprehensive program of faculty assessment. Faculty are particularly well qualified to critique their colleagues teaching when the objective is to improve quality of instruction because they are in a position to assess several aspects of teaching better than students, academic administrators, and other constituencies of the academic community. Large proportions of faculty in this study indicated they would take part in four methods of formative peer review—classroom observation, videotaping of classes, evaluation of course materials, and assessment of their evaluation of the academic work of students—and they provide important information on factors that might detract from their participation, on conditions that might enhance the process, and on the benefits they and their students, colleagues, and institutions might receive as a result of their participation.     

From Expression to Dialogue: A Study of Social Action Literacy Projects in an Urban School Setting

This paper discusses the revision of a literacy workshop from its basis in expressivist philosophy and pedagogy toward a more socially and critically based practice with urban adolescents. As part of a larger research project, a classroom teacher and a university researcher collaborated to include social action projects within a workshop approach to reading and writing. This paper presents both the positive developments brought about by these social action projects and the difficult dilemmas raised by the enactment of the projects in the classroom. Specifically, I use one of the social action performances to examine how discursive and relational practices and individualistic ideologies held by classroom and school participants shaped the projects in disturbing ways. I highlight how the students engaged in interesting—albeit often superficial—dialogues but did not necessarily learn to taken action to challenge structures and systems that marginalize or oppress people. The paper concludes with suggestions for future revisions of literacy workshops in ways that would allow students to develop literacy skills for taking action in multiple social worlds.     

The Nature of Discourse throughout 5E Lessons in a Large Enrolment College Biology Course

Large enrolment science courses play a significant role in educating undergraduate students. The discourse in these classes usually involves an instructor lecturing with little or no student participation, despite calls from current science education reform documents to elicit and utilize students’ ideas in teaching. In this study, we used the 5E instructional model to develop and implement four lessons in a large enrolment introductory biology course with multiple opportunities for teacher-student and student-student interaction. Data consisted of video and audio recordings of whole-class and small-group discussions that took place throughout the study. We then used a science classroom discourse framework developed by Mortimer and Scott (2003) to characterize the discursive interactions in each 5E lesson phase. Analysis of the data resulted in two assertions. First, the purpose, communicative approach, patterns of discourse, and teaching interventions were unique to each 5E lesson phase. Second, the type of lesson topic influenced the content of the discourse. We discuss how the findings help characterize the discourse of each phase in a 5E college science lesson and propose a model to understand internalization through discursive interaction using this reform-based approach. We conclude with implications for facilitating discourse in college science lessons and future research. This study provides support for using the discourse framework to characterize discursive interaction in college science courses.     

Conceptual knowledge in talk and text: What does it take to understand a science question?

What is referred to as conceptual knowledge is one of the mostimportant deliverables of modern schooling. Following the dominance of cognitive paradigmsin psychological research, conceptual knowledge is generally construed assomething that lies behind or under performance in concrete social activities. In the presentstudy, students' responses to questions, supposedly tapping conceptual knowledge,have been studied as parts of concrete communicative practices. Our focus has been onthe differences between talk and text. The most frequent approach for generatinginsight into conceptual knowledge is by means of written tests. However, the very mannerin which people handle the demands of this particular form of mediation is seldomattended to. This problem has been studied by means of two items taken from theinternational comparison of knowledge and achievement in mathematics and science, TIMSS.The results reveal that it is highly doubtful if the items test knowledge of scienceconcepts to any significant extent. In both instances, the difficulties students have, asrevealed in the interview setting, seem to be grounded in problems in understanding somedetails in the written questions. These difficulties are generally easily resolved in aninteractive setting. It is argued that the low performance on these items can to a largeextent be accounted for by the abstract and highly demanding form of communication that iswritten language.     

The Things they Carry: Ideology in an Urban Teacher Professional Community

This article provides an opportunity to extend the discussion about teacher communities as part of complex school reform models, specifically centered on those communities whose membership is drawn on a semi-voluntary basis. Through a sixteen-month long ethnography, I document the activities of an urban teacher professional community (TPC) at a high school located in a large city in the Northeast, serving a majority of linguistically and culturally diverse students. Guided by Sharp and Greens definition of teacher ideologies, the study focuses on how TPC members negotiated curriculum, teacher learning, and student discipline, carrying ideologies that impacted the outcomes of the communitys work, originally intended to increase teacher collaboration and foster quality teaching.Jorgelina Abbate-Vaughn is an Assistant Professor in the Department of Curriculum and Instruction at the University of Massachusetts-Boston. Her research interests center on the possibilities and challenges that urban schools pose, on school reform approaches, on teacher preparation, and on e.ective educational approaches for low-income, culturally and linguistically diverse (LCLD) students.
