Students' learning in science lessons: towards understanding the learning process

Constructivist views of learning have been applied to science education largely as a response to attempts to understand the origins of students' misconceptions in science, and therefore the learning process. As part of this effort to understand learning in science lessons, Appleton (1989) proposed a learning model drawn mainly from Piagetian (1978) ideas and generative learning theory (Osborne & Wittrock, 1983). This paper explores the development and evolution of the learning model as other constructivist view were applied, and as the model was tested against students' responses in science lessons. The revised model finally arrived at is then examined. It was found to be a useful means of describing student's learning processes during a science lesson. Specializations: primary teacher education, teaching strategies in science, cognitive change and learning theories. Specializations: secondary science teacher education, chemical education.     

Grade 10 Students' perceptions of and attitudes toward science teaching and school science

Grade 10 students' perceptions of classroom practices and activities, as well as their attitudes toward science teaching and school science, were assessed in the Westend School District (pseudonym) in British Columbia, using both quantitative (statistics of Likert-type scales) and qualitative (critical interpretive analysis of interview data) methods. The major findings of the study were that students do not appreciate the most prevailing contemporary practices in science classes, perceived by them as mainly the copying of the teacher's notes, and that they prefer science teaching and learning in which they take an active and responsible part. Additionally, teaching style appears to be the major determinant of high school students' attitudes toward science and science teaching. No change in students' perceptions of and attitudes toward science teaching and school science (in 1989 compared with 1986) could be detected in spite of the impact made by the recently advocated constructivist and science-technology-society (STS) approaches on science curriculum and science education. It is argued, therefore, that more emphasis must be placed on the science teachers' role and their teaching style if an educational change in the constructivist/STS direction is to be achieved.     

The interaction of learning environments and student discourse about knowing,learning, and the nature of science: Two longitudinal case studies

This is one of a series of studies conducted by a high school physics teacher, who used constructivist referents to plan and enact the curriculum, and to understand and improve the learning environment in his physics classes. Data were collected in the course of a two-year physics course including (a) repeated administrations of a classroom learning environment survey, (b) written essays on the topics of knowing, learning, and classroom learning environment, and (c) interviews. While there was a general trend for students to adopt more constructivist views of knowing and learning, there was also a small number who resisted to adapt to the constructivist learning environment in their physics course. Two case studies of individual students are used to illustrate the interactions of the learning environment, student understanding of scientific knowledge, and the nature of science, and students' views of their own learning.     

Nonscience majors learning science: A theoretical model of motivation

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large‐enrollment college science course that satisfies a core curriculum requirement. Based on a social‐cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster science achievement. Structural equation modeling was used to examine the hypothesized relationships among the variables. The students' motivation, as measured by the Science Motivation Questionnaire (SMQ), had a strong direct influence on their achievement, as measured by their science grade point average. The students' motivation was influenced by their belief in the relevance of science to their careers. This belief was slightly stronger in women than men. Essays by the students and interviews with them provided insight into their motivation. The model suggests that instructors should strategically connect science concepts to the careers of nonscience majors through such means as case studies to increase motivation and achievement. © 2006 Wiley Periodicals, Inc.

Knowing and teaching science: the constructivist paradox

This paper addresses the parallel between the changes in students' and teachers' learning advocated by constructivist science educators. It begins with a summary of the epistemology of constructivism and uses a vignette drawn from a set of case studies to explore the impact of a constructivist science in‐service programme on an experienced and formal elementary science teacher. Judged by constructivist standards, the teacher described in the vignette makes very little progress. The irony of applying a constructivist critique to his work, however, is that it fails to treat the teachers' imperfect knowledge of teaching with the same respect as constructivists treat students' imperfect learning of science. The remainder of the paper explores this constructivist paradox, and suggests that‐like students' knowledge of science‐teachers' knowledge of constructivist science teaching is likely to grow through slow and gradual re‐formation of their established understanding of classroom theory and practice.     

The Classroom Practice of a Prospective Secondary Biology Teacher and His Conceptions of the Nature of Science and of Teaching and Learning Science

We describe research carried out with a prospective secondary biology teacher, whom we shall call Miguel. The teacher’s conceptions of the nature of science and of learning and teaching science were analyzed and compared with his classroom practice when teaching science lessons. The data gathering procedures were interviews analyzed by means of cognitive maps and classroom observations. The results reflected Miguel’s relativist conceptions of the nature of science that were consistent with his constructivist orientation in learning and teaching. In the classroom, however, he followed a strategy of transmission of external knowledge based exclusively on teacher explanations, the students being regarded as mere passive receptors of that knowledge. Miguel’s classroom behavior was completely contrary to his conceptions, which were to reinforce the students’ alternative ideas through debate, and not by means of teacher explanation.     

University science students as curriculum planners,teachers, and role models in elementary school classrooms

Project SEARCH (Science Education and Research for CHildren) is an outreach program designed to teach science and to foster positive attitudes toward science. Through the project, university science students bring activity-based learning, plus materials and content expertise, to local classrooms and after-school programs. Using observations, surveys, and interviews, we examined the experiences of these students as curriculum planners, teachers, and role models for the children. We found that teachers value the enthusiasm and the resources provided by the SEARCH students. Children were engaged in the activities and looked forward to the students' visits. They also see them as positive and diverse models for the role of scientist. But there were often problems in the areas of preparation, scheduling, and communication, and the classroom activities often replicated traditional didactic lessons. The SEARCH experience highlights both the value of providing diverse and challenging experiences for children, and the need for dialogue and reflection on those experiences. Despite several concerns, the SEARCH model is one that deserves expansion and further study as it is extended into new settings. © 1997 John Wiley & Sons, Inc. J Res Sci Teach 34 : 69–88, 1997.     

Learning from inquiry‐based laboratories in nonmajor biology: An interpretive study of the relationships among inquiry experience,epistemologies, and conceptual growth

The use of inquiry‐based laboratory in college science classes is on the rise. This study investigated how five nonmajor biology students learned from an inquiry‐based laboratory experience. Using interpretive data analysis, the five students' conceptual ecologies, learning beliefs, and science epistemologies were explored. Findings indicated that students with constructivist learning beliefs tended to add more meaningful conceptual understandings during inquiry labs than students with positivist learning beliefs. All students improved their understanding of experiment in biology. Implications for the teaching of biology labs are discussed. © 2003 Wiley Periodicals, Inc.

Constructivism in Practice: an Exploratory Study of Teaching Patterns and Student Motivation in Physics Classrooms in Finland,Germany and Switzerland

For the last three decades, moderate constructivism has become an increasingly prominent perspective in science education. Researchers have defined characteristics of constructivist-oriented science classrooms, but the implementation of such science teaching in daily classroom practice seems difficult. Against this background, we conducted a sub-study within the tri-national research project Quality of Instruction in Physics (QuIP) analysing 60 videotaped physics classes involving a large sample of students (N?=?1192) from Finland, Germany and Switzerland in order to investigate the kinds of constructivist components and teaching patterns that can be found in regular classrooms without any intervention. We applied a newly developed coding scheme to capture constructivist facets of science teaching and conducted principal component and cluster analyses to explore which components and patterns were most prominent in the classes observed. Two underlying components were found, resulting in two scales—Structured Knowledge Acquisition and Fostering Autonomy—which describe key aspects of constructivist teaching. Only the first scale was rather well established in the lessons investigated. Classes were clustered based on these scales. The analysis of the different clusters suggested that teaching physics in a structured way combined with fostering students’ autonomy contributes to students’ motivation. However, our regression models indicated that content knowledge is a more important predictor for students’ motivation, and there was no homogeneous pattern for all gender- and country-specific subgroups investigated. The results are discussed in light of recent discussions on the feasibility of constructivism in practice.     

BOOK REVIEW

This paper describes an investigation in Korea of the extent to which a new general science curriculum, reflecting a constructivist view, has influenced the classroom learning environment in grade 10 science. The Constructivist Learning Environment Survey (CLES) was selected for the investigation and translated into Korean. Other objectives of this study were to determine whether the Korean version of the CLES is valid and reliable, differences between students’ perceptions of their actual and preferred learning environment and associations between students’ perceptions of the constructivist learning environment and their attitude to science. The Korean‐language version of the CLES was found to be valid and reliable and grade 10 students did perceive a more constructivist learning environment than grade 11 students who had not been exposed to the new curriculum. This suggested that efforts of curriculum reform had produced some positive effects. Students tended to prefer a more positive environment than what was perceived to be present and statistically significant relationships were found between classroom environment and student attitudes. These relationships suggest that favourable student attitudes could be promoted in classes where students perceive more personal relevance, share control with their teachers and negotiate their learning.     

Problem solving in science lessons: How students explore the problem space

This report examines, from a constructivist framework, how students presented with discrepant event problems during science lessons begin the problem solving process by exploration of the problem space. Three discrepant events were presented to five classes of eleven to thirteen year-olds using three different teaching strategies identified from the literature. The teaching strategies used teacher demonstrations followed by students asking the teacher questions, teacher demonstrations followed by an explanation by the teacher, and small groups of students under the guidance of the teacher. Data were collected from field notes, video tapes of the lessons, and student interviews using a stimulated recall technique to elicit the students' thinking during the lessons. The extent to which students could explore the problem space was found to be determined by the teaching strategy used, as the first and last strategies encouraged students to find their own explanations. Different information sources were also available in each of the teaching strategies. That is, exploration of the problem space was inextricably linked to the social context, partially determined by the teaching strategy. Because of constraints imposed by each teaching strategy none of those used was considered entirely satisfactory. An alternative strategy is suggested from a combination of aspects of the strategies trialled.     

Students' Reports of Their Cognitive Processes and Level of Understanding During Regular Classroom Instruction

The study was designed in an attempt to gain greater understanding of the kinds of learning processes engaged in by students during regular classroom instruction, and at investigating the students' level of understanding and problems in understanding parts or all of the lessons. Six school levels of male and female students from 44 secondary and pre-university classes (N=2719) were the subjects of this study. During the lessons, students and teachers were observed and video-taped. Following the lessons, students' reports of their learning processes were obtained using a questionnaire. The questionnaire also served as the basis for a follow-up interview of four randomly selected students from each of the sampled classes. The whole procedure was repeated for each class within a one-month period and for a different curricular area.

Analyses of student responses showed that more of the average ability students as compared to the high or low ability students reported understanding all of the lessons. However, the higher ability students were more likely to report using specific cognitive strategies to monitor their understanding of the lessons and in processing intellectual tasks and lesson content. They were able to provide more elaborate and more specific reasons for not understanding parts of the lessons. The results were interpreted in terms of physical and organizational characteristics of educational classrooms in Singapore. Instructional implications are discussed in relationship to both the findings and previous literature.     

Combating Stereotypes of the Scientist Among Pre-service Science Teachers in Nigeria

This paper looks at the effect of instruction on pre-service science teachers' conceptions of the scientist. Twenty-six pre-service science teachers involved in a 14-week course were the subjects. The constructivist teaching approach was adopted. The students' preconceptions were the starting point for the teaching. Seven students were selected for in-depth interview to determine the reasons for their positions (change or no change in view at the end of the period). It was found that instruction enhanced better conceptions of the scientist. The pre-test to post-test change scores differed from zero and the difference was significant at the 0·05 level of significance. However, the interview revealed that the changes in conceptions were mediated by the students' life worldviews. We therefore conclude that whereas remediating strategies enhance understanding (comprehension), worldview of the students has a greater effect on meaningful learning (apprehension).     

Senior High School Student Biology Learning in Interactive Teaching

This paper reports Grade 12 students’ biology learning during interactive teaching classes in 2001 in Taiwan. The researcher as teacher, working within an interpretive framework, set out to improve her senior high school student biology teaching and learning. An intervention based on a social constructivist view of learning was designed, implemented and evaluated. The findings of this study indicate that intervention students’ cognitive development was facilitated, their reasoning and social abilities were enhanced, and they enjoyed the lessons more. Their first term examination outcomes were comparable with those in the traditional teaching classes. This study, therefore, provides an example for how interactive teaching, based on a social constructivist view of learning, can be effectively used for teaching and learning biology in the senior high school in Taiwan.     

Effectiveness of instruction based on the constructivist approach on understanding chemical equilibrium concepts

The purpose of this study was to identify misconceptions concerning chemical equilibrium concepts and to investigate the effectiveness of instruction based on the constructivist approach over traditional instruction on 10th grade students' understanding of chemical equilibrium concepts. The subjects of this study consisted of 71 10th grade students from two chemistry classes of the same teacher. Each teaching strategy was randomly assigned to one class. The data were obtained from 32 students in the experimental group taught with instruction informed by the constructivist approach and 39 students in the control group taught with traditional instruction. The data were analysed using analysis of covariance. The results indicated that the students who used the constructivist principles-oriented instruction earned significantly higher scores than those taught by traditional instruction in terms of achievement related to chemical equilibrium concepts. In addition, students' previous learning and science process skills each made a significant contribution to the achievement related to chemical equilibrium concepts. In light of the findings obtained from the results, an additional misconception of chemical equilibrium concepts was determined in addition to the misconceptions in related literature. This misconception is that when one of the reactants is added to the equilibrium system, the concentration of the substance that was added will decrease below its value at the initial equilibrium.     

Misconceptions Reconceived: A Constructivist Analysis of Knowledge in Transition

This article uses a critical evaluation of research on student misconceptions in science and mathematics to articulate a constructivist view of learning in which student conceptions play productive roles in the acquisition of expertise. We acknowledge and build on the empirical results of misconceptions research but question accompanying views of the character, origins, and growth of students' conceptions. Students have often been viewed as holding flawed ideas that are strongly held, that interfere with learning, and that instruction must confront and replace. We argue that this view overemphasizes the discontinuity between students and expert scientists and mathematicians, making the acquisition of expertise difficult to conceptualize. It also conflicts with the basic premise of constructivism: that students build more advanced knowledge from prior understandings. Using case analyses, we dispute some commonly cited dimensions of discontinuity and identify important continuities that were previously ignored or underemphasized. We highlight elements of knowledge that serve both novices and experts, albeit in different contexts and under different conditions. We provide an initial sketch of a constructivist theory of learning that interprets students' prior conceptions as resources for cognitive growth within a complex systems view of knowledge. This theoretical perspective aims to characterize the interrelationships among diverse knowledge elements rather than identify particular flawed conceptions; it emphasizes knowledge refinement and reorganization, rather than replacement, as primary metaphors for learning; and it provides a framework for understanding misconceptions as both flawed and productive.     

A Cross-cultural Study of Classroom Learning Environments in Australia and Taiwan

This research is distinctive in that it not only provides an example of one of the few cross-cultural studies in science education, but also it used multiple research methods from different paradigms in exploring classroom learning environments in Taiwan and Australia. This article describes the validation and use of an English and Mandarin version of the What is Happening in this Class? (WIHIC) questionnaire in junior high school science classes in Australia and Taiwan. When the WIHIC was administered to 1,081 students in 50 classes in Australia and to 1,879 students in 50 classes in Taiwan, data analysis supported the reliability and factorial validity of the questionnaire, and revealed differences between Taiwanese and Australian classrooms. Although the study commenced from a more positivistic framework, favouring a more objectivist view, as the study progressed, it employed an interpretative framework and drew on elements of constructivist and critical theory paradigms. This article outlines the researchers' use of multiple research methods including classroom observations, in-depth interviews and narratives. The themes which emerged from the data gathered using these methods helped to make sense of classroom environments that were created in each country.

     

Guidance counsellor and student perceptions of counselling lessons in Finnish comprehensive school

The present study concerns counselling lessons in the final grade of Finnish comprehensive school. It focuses on the relevance of counselling lessons to the students on the basis of their personal assessments. Methodologically, the issues at stake centre around the simultaneous examination of the classroom setting from the point of view of different participants.The methods employed are the so called stimulated recall interview and the content analysis of qualitative interview data. The observations presented are based on interviews of guidance counsellors and of their students after the lessons, which dealt with work and students' future choices.According to the observations, the students' perceptions on the relevance of the lessons varied to a major degree. Most of them regarded them as easy and routine school work. Also the interpretations of the teacher and the students differed in many aspects. In particular, only a minority of the students shared the teachers' views about the aims of the lesson.In general, the implications of the study for career education are fairly obvious. If it is organized as an ordinary classroom activity, students are inclined not to consider it to be personally relevant to them.     

Can teachers predict their students' wait time preferences?

The study examined students' preferences for wait times of 3 seconds versus .9 second, teachers' ability to accurately predict their students' preferences, and the reasons both groups of participants gave for their choices. Thirty-five middle school science classes watched two versions of a videotaped science review lesson. The versions differed only in length of time the teacher paused after questions before she called on students to respond. When asked which version would produce more learning and when asked which version they preferred (after being told how the two versions differed), significantly more students chose the one with the longer wait time. Significantly more teachers predicted these choices accurately than inaccurately. Students identified think time, time use, teacher helpfulness, and topic ease as reasons for their choices.
