The development of science epistemology in senior science courses: A quantitative study

<p>Epistemological development is a pivotal aspect of liberal education because the ability to distinguish between knowledge and pseudo-knowledge and the ability to use the particular methods of reasoning associated with various disciplinary fields equips people to make judgements in complex issues. The present study examines the extent to which studying each of the different science disciplines in secondary years 12 and 13 supports the development of science epistemology. A further aim was to determine the relationship between epistemological development in science and the completion of inquiry-type coursework. Data were collected from 735 year 12 and 13 students from 11 schools, mainly from the Wellington region. A survey, designed for this study, comprised statements about the nature of science and scientific argumentation conceptions, two pivotal aspects of science epistemology. Using a quasi-experimental design, this quantitative study explores the extent of the development of science epistemology over a year of studying science, by comparing students’ scores in Term 1 with scores in Term 3 on the instrument. The findings showed a more advanced epistemic view among science students; however, a positive effect of science studies on epistemic development was not evident. It was concluded that a greater emphasis on authentic inquiry is essential for epistemic development and, while understanding of the philosophical assumptions underpinning scientific knowledge is important, this should arise from authentic science inquiries – or the processes of science – rather than being taught in isolation from the practice of the discipline of science. This leads to a question the extent to which an emphasis should be placed on the ontological aspects of the philosophy and the sociology of science, potentially at the expense of developing sound understanding of science epistemology.</p>

Reintroducing “the” Scientific Method to Introduce Scientific Inquiry in Schools?

There are some crucial critiques on scientific inquiry and “the” Scientific Method in current science education. Recent research literature is replete with arguments against inquiry’s legitimacy to be included in science classes, and it has even been abandoned from the Next Generation Science Standards. Critics of scientific inquiry in schools blame it to be a caricature of authentic inquiry suffering from five shortcomings: (1) knowledge becomes desocialized from its generative contexts, (2) scientific inquiry in schools suggests methodological monism favoring (3) a primacy of experimentation, (4) which portrays scientific inquiry as a knowledge automaton (5) raising an illusion of determination with regard to the generation of knowledge. This article argues for a reorientation of scientific inquiry in schools tentatively embracing “the” Scientific Method anew since critics appear not to sufficiently consider that scientific inquiry operates differently in schools from science. It will be shown that most critiques can be defused when untangling such an illegitimate mix-up of science proper with school science. It will be argued that current (and recent) descriptions of how science generates knowledge lack authoritative validity and should be fundamentally revisited. “The” Scientific Method will be shown to be a valid idealization that can serve as a frame of reference for introductory science classes. Still, it is understood that science education needs to extend beyond “the” Scientific Method if it is to prepare for science-related careers.

Science teachers’ experiences of inquiry-based learning through a serious game: a phenomenographic perspective

This study employed a phenomenographic approach to investigate science teachers’ conceptions of inquiry-based learning through a serious game. Simaula is a prototype game designed and used as a virtual practicum for eliciting understandings on how in-game inquiry was appeared to, or experienced by, the participating teachers. Group interviews with 20 secondary education science teachers revealed four qualitatively different ways of experiencing inquiry-based learning through Simaula: (a) as uncovering insights about student’s learning needs, interests and emotions; (b) as generating ideas and concepts for meaningful inquiry; (c) as a set of operations for designing and carrying out scientific research; and (d) as authentic inquiry for enabling knowledge building processes. Seven dimensions of variation have been identified viewed as contextual influences on conceptions of in-game inquiry constituting discernment of: epistemic inquiry-based learning modes; role of teacher; role of student; game-play focus; core mechanics focus; feedback and progress mechanics and game uncertainty. The results illuminated a partial in-game inquiry approach with distinct epistemic modes from developing empathy and meaning making to knowledge construction and knowledge building. The findings also indicated that game design elements played central role in shaping conceptions of in-game inquiry from focusing on rules and logic as means to completing the game’s level to understanding the complexity of core mechanics for developing and transferring in-game inquiry to the real classroom. This insinuates that distinct game design properties may be considered in terms of extending intrinsic in-game inquiry experiences to actual in-class inquiry practice.

Web-based authentic inquiry experiences in large introductory classes consistently associated with significant learning gains for all students

Background Continuous calls for reform in science education emphasize the need to provide science experiences in lower-division courses to improve the retention of STEM majors and to develop science literacy and STEM skills for all students. Open or authentic inquiry and undergraduate research are effective science experiences leading to multiple gains in student learning and development. Most inquiry-based learning activities, however, are implemented in laboratory classes and the majority of them are guided inquiries. Although course-based undergraduate research experiences have significantly expanded the reach of the traditional apprentice approach, it is still challenging to provide research experiences to nonmajors and in large introductory courses. We examined student learning through a web-based authentic inquiry project implemented in a high-enrollment introductory ecology course for over a decade. Results Results from 10 years of student self-assessment of learning showed that the authentic inquiry experiences were consistently associated with significant gains in self-perception of interest and understanding and skills of the scientific process for all students—both majors and nonmajors, both lower- and upper-division students, both women and men, and both URM and non-URM students. Student performance in evaluating the quality of an inquiry report, before and after the inquiry project, also showed significant learning gains for all students. The authentic inquiry experiences proved highly effective for lower-division students, nonmajors, and women and URM students, whose learning gains were similar to or greater than those of their counterparts. The authentic inquiry experiences were particularly helpful to students who were less prepared with regard to the ability to evaluate a scientific report and narrowed the performance gap. Conclusions These findings suggest that authentic inquiry experiences can serve as an effective approach for engaging students in high-enrollment, introductory science courses. They can facilitate development of science literacy and STEM skills of all students, skills that are critical to students’ personal and professional success and to informed engagement in civic life.

Advancing Undergraduate Laboratory Education Using Non-Model Insect Species

Over the past decade, laboratory courses have made a fundamental shift to inquiry-based modules and authentic research experiences. In many cases, these research experiences emphasize addressing novel research questions. Insects are ideal for inquiry-based undergraduate laboratory courses because research on insects is not limited by regulatory, economic, and logistical constraints to the same degree as research on vertebrates. While novel research questions could be pursued with model insect species (e.g., Drosophila, Tribolium), the opportunities presented by non-model insects are much greater, as less is known about non-model species. We review the literature on the use of non-model insect species in laboratory education to provide a resource for faculty interested in developing new authentic inquiry-based laboratory modules using insects. Broader use of insects in undergraduate laboratory education will support the pedagogical goals of increased inquiry and resesarch experiences while at the same time fostering increased interest and research in entomology.
