Inclusive science education: learning from Wizard

This case study reports on a student with special education needs in an inclusive seventh grade life science classroom using a framework of disability studies in education. Classroom data collected over 13 weeks consisted of qualitative (student and classroom observations, interviews, student work samples and video-taped classroom teaching and learning record using CETP-COP) methods. Three key findings emerged in the analysis and synthesis of the data: (1) The learning experiences in science for Wizard are marked by a dichotomy straddled between autonomy [“Sometimes I do” (get it)] and dependence [“Sometimes I don’t (get it)], (2) the process of learning is fragmented for Wizard because it is underscored by an emerging disciplinary literacy, (3) the nature of the inclusion is fragile and functional. Implications for classroom practices that support students with learning disabilities include focusing on student strengths, intentional use of disciplinary literacy strategies, and opportunities for eliciting student voice in decision making.     

Epistemological beliefs and epistemic strategies in self-regulated learning

How do epistemological attitudes and beliefs influence learning from text? We conceptualize epistemological attitudes and beliefs as components of metacognitive knowledge. As such, they serve an important function in regulating the use of epistemic strategies such as knowledge-based validation of information and checking arguments for internal consistency. We report results from two studies that investigated the effects epistemological attitudes and beliefs on the use of epistemic strategies in academic learning and the motivational states that mediate these effects. Study 1 (N = 289) tested a mediation model with epistemological attitudes (separate vs. connected knowing) and textual characteristics as distal predictors, and learning goals (learning factual knowledge vs. developing an own standpoint) as mediator variables. Separate knowing had large indirect effects on the use of epistemic strategies via the goal to develop an own point of view. In addition, learners adapted their learning goals and epistemic strategies depending on objective characteristics and the perceived familiarity of the texts they read. In Study 2 (N = 124), epistemological beliefs concerning the uncertainty of knowledge increased the use of epistemic strategies only when extrinsic study motivation was low. A mediated moderation model established this effect to be mediated by specific epistemic curiosity. These results illuminate the mechanisms of how epistemological attitudes and beliefs affect self-regulated learning. In contrast to other types of learning strategies, the use of epistemic strategies seems to be strongly and consistently linked to epistemological attitudes and beliefs.     

Software for managing complex learning: Examples from an educational psychology course

Inquiry-based instruction including problem-, project-, and case-based methods often incorporate complex sets of learning activities. The numerous activities run the risk of becoming disconnected in the minds of learners and teachers. STAR.Legacy is a software shell that can help designers organize learning activities into an inquiry cycle that is easy to understand and pedagogically sound. To ensure that classroom teachers can adapt the inquiry activities according to their local resources and needs, STAR.Legacy was built upon four types of design principles: learner centered, knowledge centered, assessment centered, and community centered. We describe how a STAR.Legacy constructed for an educational psychology course helped preservice teachers design and learn about effective inquiry-based instruction.

Piaget's epistemic subject and science education: Epistemological vs. psychological issues

Many individuals claim that Piaget's theory of cognitive development is empirically false or substantially disconfirmed by empirical research. Although there is substance to such a claim, any such conclusion must address three increasingly problematic issues about the possibility of providing an empirical test of Piaget's genetic epistemology: (1) the empirical underdetermination of theory by empirical evidence, (2) the empirical difficulty of testing competence-type explanations, and (3) the difficulty of empirically testing epistemic norms. This is especially true of a central epistemic construct in Piaget's theory — the epistemic subject. To illustrate how similar problems of empirical testability arise in the physical sciences, I briefly examine the case of Galileo and the correlative difficulty of empirically testing Galileo's laws. I then point out some important epistemological similarities between Galileo and Piaget together with correlative changes needed in science studies methodology. I conclude that many psychologists and science educators have failed to appreciate the difficulty of falsifying Piaget's theory because they have tacitly adopted a philosophy of science at odds with the paradigm-case of Galileo.An earlier version of this paper was read at the 1990 annual meeting of the N.A.R.S.T in Atlanta. I wish to thank Mansoor Niaz for making suggestions about improving the quality of the paper.     

How analogies foster learning from science texts

This article provides an introduction to extended text-based analogies used for instructional purposes in science textbooks. A theoretical framework for understanding learning via extended analogies is discussed, and examples of extended textual analogies are provided. Research which provides direction in how to optimally use analogies in science instruction is reviewed. Characteristics of good analogies, types of learners who might benefit from the use of analogies, and kinds of learning which might be facilitated are discussed. The issue of possible misconceptions generated via instructional analogies is addressed, in conjunction with suggestions for remediation. Finally, recommendations for effective use of analogies in text are made, suggestions for instructional practices accompanying textual science analogies are provided and directions for future research are suggested.     

Comprehension evaluation and regulation in learning from science texts

Metacognitive variables influence students' learning from science texts. This article deals with the comprehension monitoring abilities of secondary school science students, one of the areas of metacognition which has drawn considerable attention from researchers. The aims of the study are, in particular: (a) to know the extent to which comprehension is monitored by secondary science students as revealed by inconsistency detection in manipulated science texts, and (b) to identify the strategies used to regulate comprehension by the students who detect the inconsistencies. The results indicate that knowing that one understands or fails to understand science texts could be as important a problem as understanding proper. Besides, some incorrect regulatory strategies used by students who notice the inconsistencies in the texts are identified. These could also have an annoying influence in the regulatory behavior of students when studying regular science texts.     

Uncovering the effect of text structure in learning from a science text: An eye-tracking study

This study examined whether reading a refutational or non-refutational text would induce different cognitive processing, as revealed by eye-movement analyses. Unlike a standard expository text, a refutational text acknowledges a reader’s alternative conceptions about a topic, refutes them, and then introduces scientific conceptions as viable alternatives. Forty university students read one or the other type of text about the phenomenon of the tides. All had alternative conceptions about the topic. Findings showed that at post-test (off-line measure) refutational text readers learned more than non-refutational text readers. Outcomes regarding indices of visual behavior (on-line measures) during reading revealed that refutational text readers fixated the text segments presenting scientific concepts for a longer time overall than non-refutational text readers, in particular during the second-pass reading. Refutational text readers also fixated the refutational segments for a shorter time than non-refutational text readers for the control segments. Furthermore, all indices of visual attention predicted learning only for the refutational text readers. The more the students’ reading of the refutational text was strategic, the better they learned from it. Implications about eye-tracking methodology and the refutational effect are drawn.     

Informal learning: Student achievement and motivation in science through museum-based learning

This study examined changes in student motivation and achievement in science during a visit to a university children’s science museum. The study was based on the pretest–posttest control comparison group design with four treatment groups: control, exhibit, lesson and exhibit/lesson. The sample consisted of 228 sixth-grade students from a Louisiana public school who were randomly assigned to one of the four experimental groups. Pretest, posttest and delayed posttest measures of intrinsic motivation and achievement in science were obtained using the Children’s Academic Intrinsic Motivation Inventory and an achievement test written to measure areas of science incorporated in the museum exhibits. The data were analysed using a one-way ANOVA, dependent t tests and Pearson r. Significant differences were found within groups for (1) the lesson group in motivation and (2) the exhibit group in achievement from pretest to posttest and from posttest to delayed posttest. A significant relationship between level of motivation and science achievement was revealed for the exhibit group on the delayed posttest. There were no other significant findings to support that the treatment led to any long-term effects on motivation or achievement within any of the four experimental groups.     

Creative learning in science education

Conclusion Making sense of the world-including the world of school learning-involves making connections between new and existing experiences. Whether this process is called the construction (Piaget, 1929), the generation (Osborne & Wittrock, 1985) or the creation of meaning, the relation of new experiences to existing understandings, images, experiences, and feelings are essential to the process of learning with understanding. For many years cognitive psychology has focused on the making of logical, sequential, highly structured connections. However, the computer metaphor for human information processing and storage is now being questioned and cognitive psychologists are beginning to explore the new ‘unexplorable’-parallel, holistic, divergent, creative mental processes. In addition, this paper proposes a model of the learning process in terms of reciprocally interactive cognitive, affective, and social variables.     

Perceptions of challenge in science learning

Prior research has indicated that decisions made by students about their learning are influenced by perceptions of various factors related to the task and classroom context. This influence seems to be mediated by the extent to which the learner perceives personal challenge in what is done. This concept of personal challenge comprises both cognitive (demand) and affective (motivation) components. In the current paper, response trends of almost 4000 secondary science students to a questionnaire structured according to factors associated with challenge are considered by school, year level and gender. These trends indicate that challenge in science diminishes as students move from Years 7 to 10, due to increasingly negative perceptions of many of these factors. Results also indicate however that, through purposeful change in teaching perspectives and practices, teachers can establish and sustain students’ sense of challenge in classroom learning.     

Sex differences in science learning: Closing the gap through animations

Males traditionally outperform females on measures of both visuospatial ability and science achievement. This experiment directly tests a manipulation designed to compensate for such differences through the presentation of relevant illustrations or animations to support the construction of understanding of a specific scientific phenomenon. Males and females read a scientific text about plate tectonics that contained static illustrations, animated versions of the static illustrations, or no illustrations. Participants were assessed on their visuospatial ability and also working memory capacity. Results indicated that while males outperformed females on both the visuospatial measure and overall science learning, the presence of animations effectively eliminated performance differences for this science topic. These results suggest that sex differences in learning outcomes can be overcome by supporting the visualization of scientific phenomena.     

On Generalising from Single Case Studies: Epistemological Reflections

The aim of this paper is to explore the conditions under which generalisation from single case studies, in the sense of making inferences concerning a wider class of phenomena beyond a case, is reasonable. Two sets of conditions, in particular, provide the basis for our consideration of this issue. The first is an exploration of the impressive amount of empirical knowledge that is contained within the theories that are used to make observations, to classify phenomena, and to understand and interpret cases. The second is recognition of the role of a pattern of inference known as abduction, or inference to the best explanation, in drawing conclusions from case studies. It is argued that these two conditions, when applied to the procedures for conducting case studies, can be used to defend, as reasonable, the making of certain provisional generalisations from single cases. An epistemological procedure for testing and further justifying these generalisations, with a particular emphasis on dealing with the problem of confirmation bias, is then discussed and recommended.     

Preservice teachers' initial conceptions about assessment of science learning: The coherence with their views of learning science

This study utilized responses from Taiwanese preservice elementary teachers to describe and analyze their conceptions about the assessment of science learning and the extent that these conceptions were coherent with their views of learning science. A methodological framework of phenomenography was used for the study. The results revealed that the preservice teachers' mode of assessment was coherent with a traditional view of learning but their performance mode of assessment was not well developed. Improving preservice teachers' conception of assessment requires clarifying and reconstructing their conceptions of and coherence between assessment, curriculum, pedagogy, and learning.     

Expected benefits of web-based learning for engineering education: Examples in control engineering

This paper presents how 'teaching and learning with technologies' may improve academic education and corporate training for engineering sciences. It particularly details examples of web-based learning tools for control and open distance learning experiments developed at the Grenoble National Polytechnic Institute (INPG, France). The paper describes the observed improvements brought by information and communication technologies in the academic context at different levels: the academic institution, the teacher and finally the user. Then it presents four significant approaches to web-based learning developed at the INPG. The first three approaches are intended to enrich and complete the traditional face-to-face teaching and learning in control with highly interactive, self-learning tools, including hypertext, exercise bases, simulations, and virtual and remote laboratories. The fourth approach is seen as a substitution for traditional face-toface teaching and learning, providing open distance learning in the context of continuing education. The benefits and limits of the four approaches are discussed. Prospective developments in university teacher status and staff evolution are explored and the role of university in the international context is discussed in a generic context. Finally, advantages of distance learning for industry are presented. Benefits of e.learning are shown from the point of view of the individual and the company.
