Engaging students in active learning is linked to positive learning outcomes. This study aims to synthesise the peer-reviewed literature about 'active learning' in college science classroom settings. Using the methodology of an integrative literature review, 337 articles archived in the Educational Resources Information Center (ERIC) are examined. Four categories of in-class activities emerge: (i) individual non-polling activities, (ii) in-class polling activities, (iii) whole-class discussion or activities, and (iv) in-class group activities. Examining the collection of identified inclass activities through the lens of a theoretical framework informed by constructivism and social interdependence theory, we synthesise the reviewed literature to propose the active learning strategies (ALSs) model and the instructional decisions to enable active learning (IDEAL) theory. The ALS model characterises in-class activities in terms of the degrees to which they are designed to promote (i) peer interaction and (ii) social interdependence. The IDEAL theory includes the ALS model and provides a framework for conceptualising different levels of the general concept 'active learning' and how these levels connect to instructional decision-making about using in-class activities. The proposed ALS model and IDEAL theory can be utilised to inform instructional decision-making and future research about active learning in college science courses.
There is a growing need for public understanding about groundwater resources. Knowing what groundwater and aquifers are is fundamental to understanding more complex issues such as groundwater quality and availability. However, groundwater and related concepts are among the topics that instructors most struggle to teach. Although constructivist theories suggest that students’ preconceptions or misconceptions can be used as teaching tools, the question about exactly how remains. A resource perspective on this question states the first step involves understanding students’ preconceptions. To gain a deeper understanding of college students’ pre-instructional mental models about groundwater residence, 215 students enrolled in introductory-level environmental geoscience courses taught at two large US state universities were surveyed. An open-ended questionnaire asked participants to draw and label a concept sketch. Follow-up interviews asked participants to elaborate upon their concept sketches. Eight categories of mental models emerged from the analysis of the collected data. These results were interpreted through the lens of cognitive schema theory, which generated to four patterns of mental models. These patterns emphasize key aspects of students’ pre-instructional mental models about groundwater residence. Instructors can use this information to design instructional activities about groundwater and aquifers using a resource perspective.
Discipline‐based education research (DBER) conducted by faculty within geoscience departments can address identified needs in undergraduate geoscience education. This study explores the evolution of undergraduate geoscience education research (GER) from 1985 to 2016, primarily in terms of the types of published research and secondarily in terms of the insights this literature offers on the evolution of GER as a scholarly discipline. Stokes’ (1997) quadrant model of research types is used as a theoretical framework for the former and Kuhn's (1970) model of disciplinary paradigm for the latter. An exploratory sequential mixed‐methods approach to a systematic literature review of 1,760 articles is utilized. The period 1985–2000 is characterized by proto‐research as evidenced by the abundance of instructive and informational education articles rather than research articles. From 2000 to 2011, GER underwent a growth period characterized by the presence of applied, use‐inspired, and pure basic research. The period 2011–2016 appears to be a period of relative steady‐state conditions in the normalized number of GER publications per year. Existing gaps in knowledge about geoscience education, the evident unfamiliarity with education and social science research methodologies among authors of GER articles, and efforts to build consensus about what GER is and how to conduct it suggest that GER is preparadigmatic or at a low paradigm state. That is, GER is an immature discipline as far as the evolution of a discipline goes. A path forward is proposed for the continued evolutionary growth of GER. This study provides new perspectives on the emergence of GER as a discipline that can be used as a basis for studies on cross‐disciplinary DBER comparisons.
Student attitudes about learning science and student ideas about the nature of science were compared at the end of two astronomy courses taught in Fall 2007, a course with a traditional astronomy curriculum and a transformed course, whose traditional astronomy curriculum was supplemented by an embedded curriculum that explicitly addressed the nature of science and student metacognition (i.e., thinking about one's own thinking.) The embedded curriculum in the transformed course gave students practice at evaluating examples of valid science and pseudoscience found on the internet; it also provided students opportunities to discuss what they think about learning science. Student attitudes and ideas were assessed using the epistemological beliefs assessment for physical science (EBAPS) survey, interviews, and written responses to an open-ended exam question. Our results indicate that the embedded curriculum led the majority of students in the transformed course to think that anyone can learn science, whereas a majority of students in the traditional course thought that only individuals with innate abilities can learn science and think scientifically. Students in the transformed course also reported much more confidence in their ability to evaluate the scientific validity of information found on the internet. Furthermore, students from the transformed course valued making sense of science more than students from the traditional course. The embedded curriculum could readily be used in any course for nonscience majors, not just introductory astronomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
