The Virtual Solar System Project: Developing Conceptual Understanding of Astronomical Concepts Through Building Three-Dimensional Computational Models

The Virtual Solar System (VSS) course described in this paper is one of the first attempts to integrate three-dimensional (3D) computer modeling as a central component of an introductory undergraduate astronomy course. Specifically, this study assessed the changes in undergraduate university students' understanding of astronomy concepts as a result of participating in an experimental introductory astronomy course in which the students constructed 3D models of different astronomical phenomena. In this study, we examined students' conceptual understanding concerning three foundational astronomical phenomena: the causes of lunar and solar eclipses, the causes of the Moon's phases, and the reasons for the Earth's seasons. Student interviews conducted prior to the course identified a range of student alternative conceptions previously identified in the literature regarding the dynamics and mechanics of the Solar System. A previously undocumented alternative conception to explain lunar eclipses is identified in this paper. The interviews were repeated at the end of the course in order to quantitatively and qualitatively assess any changes in student conceptual understanding. Generally, the results of this study revealed that 3D computer modeling can be a powerful tool in supporting student conceptualization of abstract scientific phenomena. Specifically, 3D computer modeling afforded students the ability to visualize abstract 3D concepts such as the line of nodes and transform them into conceptual tools, which in turn, supported the development of scientifically sophisticated conceptual understandings of many basic astronomical topics. However, there were instances where students' conceptual understanding was incomplete and frequently hybridized with their existing conceptions. These findings have significant bearing on when and in what domains 3D computer modeling can be used to support student conceptual understanding of astronomy concepts.     

The impact of three‐dimensional computational modeling on student understanding of astronomy concepts: a qualitative analysis

In this study, we explore an alternate mode for teaching and learning the dynamic, three‐dimensional (3D) relationships that are central to understanding astronomical concepts. To this end, we implemented an innovative undergraduate course in which we used inexpensive computer modeling tools. As the second of a two‐paper series, this report focuses on the qualitative differences of students' understandings of both spatial and declarative knowledge domains as reflected by their two distinct learning environments — a traditional astronomy classroom and an experimental astronomy course grounded in problem‐solving and modeling with dynamic, 3D, computational modeling software. We found that students who constructed 3D computational models tended to have a more scientifically sophisticated understanding of dynamic spatial relationships, whereas students in the traditional class developed more accurate understandings of the properties and general facts and figures regarding celestial bodies.     

The impact of three‐dimensional computational modeling on student understanding of astronomical concepts: a quantitative analysis

The increased availability of computational modeling software has created opportunities for students to engage in scientific inquiry through constructing computer‐based models of scientific phenomena. However, despite the growing trend of integrating technology into science curricula, educators need to understand what aspects of these technologies promote student learning. This study used a multi‐method research approach involving both quantitative (Paper 1) and qualitative data (Paper 2) to examine student conceptual understanding of astronomical phenomena, relative to two different instructional experiences. Specifically, based on students' understandings of both spatial and declarative knowledge, we compared students who had constructed three‐dimensional computational models with students who had experienced traditional lecture‐based instruction. Quantitative analysis of pre‐interview and post‐interview data revealed that construction of three‐dimensional models best facilitated student understandings of spatially related astronomical concepts — whereas traditional instruction techniques best facilitated student understandings of fact‐oriented astronomical knowledge. This paper is the first in a two‐paper set that continues our line of research into whether problem‐based courses such as the Virtual Solar System course can be used as a viable alternative to traditional lecture‐based astronomy courses.     

Learning through Making: Emerging and Expanding Designs for College Classes

As higher education institutions seek to prepare an increasingly diverse population of students for a rapidly changing future, makerspaces offer a pedagogical approach for engaging all learners in active thinking and hands-on learning while promoting creativity, problem solving, and collaboration skills. In this paper, we discuss ways to integrate makerspaces and maker-centered learning within undergraduate and graduate college courses that reach students from majors ranging across the college and university curriculum. We highlight four courses, each taken by students at different points within their academic programs of study: a) digital media production & 3D modeling in a first-year seminar, b) poetry writing and 3D modeling and printing in a flipped learning course, c) wiki page building workshops for future teachers, and d) learning, media, and technology undergraduate/graduate courses. Makerspace experiences are ongoing features of each course, but not in the same ways, offering models that faculty can use in adapting their courses to include more active and applied learning for students.     

Situated Learning with Online Portfolios, Classroom Websites and Facebook

In this article we describe the evolution of an elective course designed specifically for undergraduate students in our pre-service teacher education program. This course is intended to prepare these undergraduate students as future teachers—helping them to make effective and creative uses of technology in learning settings. This course emphasizes learning to learn with and about technology, in the ever-changing context of educational technology. Generally speaking, we outline and describe three key goals of teaching young teachers to thoughtfully integrate technology into a real-world classroom. First, the course emphasizes learning to explore and learn proactively by engaging in learning by design activities. Second, students are given an opportunity to try a wide variety of innovative technologies through explorations of their own choosing. Finally, we attempt to leverage the power of online community building for learning by harnessing the ubiquity and convenience of tools like Facebook. We look into the future with great hope and enthusiasm that our preservice teachers will lead the way in integrating new technologies into their teaching in ways that will benefit their students, colleagues, and the greater education community.     

Educational Standards: Mapping Who We Are and Are to Become

Educational technology supports meaningful learning and enables the presentation of spatial and dynamic images, which portray relationships among complex concepts. The Technology-Enabled Active Learning (TEAL) Project at the Massachusetts Institute of Technology (MIT) involves media-rich software for simulation and visualization in freshman physics carried out in a specially redesigned classroom to facilitate group interaction. These technology-based learning materials are especially useful in electromagnetism to help students conceptualize phenomena and processes. This study analyzes the effects of the unique learning environment of the TEAL project on students' cognitive and affective outcomes. The assessment of the project included examining students' conceptual understanding before and after studying electromagnetism in a media-rich environment. We also investigated the effect of this environment on students' preferences regarding the various teaching methods. As part of the project, we developed pre- and posttests consisting of conceptual questions from standardized tests, as well as questions designed to assess the effect of visualizations and experiments. The research population consisted of 811 undergraduate students. It consisted of a small- and a large-scale experimental groups and a control group. TEAL students improved their conceptual understanding of the subject matter to a significantly higher extent than their control group peers. A majority of the students in the small-scale experiment noted that they would recommend the TEAL course to fellow students, indicating the benefits of interactivity, visualization, and hands-on experiments, which the technology helped enable. In the large-scale implementation students expressed both positive and negative attitudes in the course survey.     

Student Learning and Performance in Information Systems Courses: The Role of Academic Motivation

Despite the need for information technology knowledge in the business world today, enrollments in information systems (IS) courses have been consistently declining. Student performance in lower level IS courses and student assumptions about the level of difficulty of the courses seem to be reasons for lower enrollments. To understand how student motivation may explain learning outcomes in introductory IS courses, this study investigates the impact of intrinsic and extrinsic academic motivations as framed by self‐determination theory on two measures of learning outcomes: (1) student self‐reported measures of learning and (2) actual grades obtained in courses and course components. Using 269 student responses collected in a second‐year undergraduate core course and a first‐year MBA core course, both of which are offered in a traditional face‐to‐face classroom environment, study hypotheses are analyzed. Results indicate that the motivational model explains both the affective and cognitive perceptions of learning held by students. In examining overall grades and grades in course components, the motivational model, however, was unable to sufficiently explain student performance. Data also indicate that there are significant differences between undergraduate and graduate students in terms of their motivation and learning outcomes.

Assessment for learning: a catalyst for student self-regulation

The development of students as lifelong, self-regulating learners is a valued outcome of higher education. To this end, the current project investigated how students in an undergraduate course experienced and responded to a teaching–learning environment where they were expected to take responsibility for their learning. The pedagogic environment of this course was grounded in strategies and activities associated with assessment for learning (AfL). As such, students were expected to participate in activities that provided them with opportunities to exercise control over their learning. Data gathering comprised individual semi-structured interviews and the collection of artefacts. Findings indicated goals helped students know where they were going; exemplars provided insights into what was expected and what constituted quality work; course activities elicited evidence of learning; dialogic interactions around these generated feedback about understandings and progress; the evaluation of exemplars developed evaluative knowledge, skill and expertise; peer review and feedback provided an authentic context for evaluation and monitoring of works-in-progress. It was concluded that, while each of the AfL strategies contributed to student self-regulation, the full impact of AfL as a catalyst for self-regulated learning was realised in the cumulative and recursive effect these strategies had on students’ thinking, actions and feelings.     

Diversity of Students' Views about Evidence,Theory, and the Interface between Science and Religion in an Astronomy Course

Arguments for teaching about the nature of science have been made for several decades. The most recent science education policy documents continue to assert the need for students to understand the nature of science. However, little research actually explores how students develop these understandings in the context of a specific course. We examine the growth in students' understanding about the nature of astronomy in a one‐semester college course. In addition to student work collected for 340 students in the course, we also interviewed focus students three times during the course. In this article we briefly describe class data and discuss in detail how five students developed their ideas throughout the course. In particular, we show the ways in which students respond to instruction with respect to the extent to which they (a) demand and examine evidence used for justifying claims, (b) integrate scientific and religious views, and (c) distinguish between scientific and nonscientific theories. © 2000 John Wiley & Sons, Inc.

Peer Learning and Support of Technology in an Undergraduate Biology Course to Enhance Deep Learning

This study offers an innovative and sustainable instructional model for an introductory undergraduate course. The model was gradually implemented during 3 yr in a research university in a large-lecture biology course that enrolled biology majors and nonmajors. It gives priority to sources not used enough to enhance active learning in higher education: technology and the students themselves. Most of the lectures were replaced with continuous individual learning and 1-mo group learning of one topic, both supported by an interactive online tutorial. Assessment included open-ended complex questions requiring higher-order thinking skills that were added to the traditional multiple-choice (MC) exam. Analysis of students’ outcomes indicates no significant difference among the three intervention versions in the MC questions of the exam, while students who took part in active-learning groups at the advanced version of the model had significantly higher scores in the more demanding open-ended questions compared with their counterparts. We believe that social-constructivist learning of one topic during 1 mo has significantly contributed to student deep learning across topics. It developed a biological discourse, which is more typical to advanced stages of learning biology, and changed the image of instructors from “knowledge transmitters” to “role model scientists.”     

Analyzing service-learning reflections through Fink's taxonomy

Reflection is an increasingly essential component of experience-based learning in higher education to encourage students to draw connections between theoretical and practical knowledge and experiences. This qualitative study examines the reflections of undergraduate students in a service-learning course for secondary English teacher candidates. The authors use Fink's taxonomy of significant learning as a lens through which to examine the learning within and critical natures of students’ reflections. Findings from this study suggest that to consider and extend students’ academic content knowledge and to move students toward new and critical understandings of their service work, reflections should direct students toward more explicit considerations of academic course content over a period of time. To help students write critical reflections that achieve both academic and personal growth learning goals, the authors recommend explicitly teaching the reflective mode, introducing students to Fink's taxonomy, and instructing students to include course content in their reflections.     

How to use (five) curriculum design principles to align authentic learning environments,assessment, students’ approaches to thinking and learning outcomes

In this article, we articulate five principles of curriculum design and illustrate their application in a third‐year undergraduate course for environmental and ecological scientists. In this way, we provide a practical framework for others wishing to enhance their students’ learning. To apply the five principles, we created a learning environment consisting of a broad range of learning resources and activities which were structured and sequenced with an integrated assessment strategy. The combined effect of this ensured alignment between the learning environment we created, the thinking approaches students used and the learning outcomes they achieved. More specifically, the assessment activities guided students by requiring them to recognise when their understanding was limited – and then to engage them in thinking approaches that would develop their understanding further. By providing a framework of thoughts, ideas and information, we sought to progressively enhance the sophistication of our learners’ thinking. Thus, the assessment required students to integrate, synthesise and construct their understandings in ways consistent with the discipline and the professional pathways on which they had embarked. We intend that this illustration will act as a guide to other academics to adopt the same principles in their teaching.     

Preferences for Team Learning and Lecture-Based Learning Among First-Year Undergraduate Accounting Students

This study investigates students’ preference for team learning and its effectiveness, compared to lecture-based learning. A quasi-experiment was set up in a financial accounting course in the first-year undergraduate of the Economics and Business Administration Program, where students had to choose between one of the two learning methods (team learning or lecture-based) and subsequently followed their preferred method of pedagogy. The quasi-experiment was administered for a first-year undergraduate class, with data for 291 students. The first objective of this study is to investigate students’ preference in relation to their gender, ability, motivation, and learning strategy. The second objective is to explore whether a team-based approach is more effective than lecture-based learning, when students participate in their preferred method. The results show that female students had a higher preference for team learning than male students. Furthermore, students with a preference for team learning had a lower ability level, were more intrinsically motivated, had less control of their learning beliefs, were more help seeking, and were more willing to share their knowledge with peers. The team learning approach resulted in increased performance, compared to the lecture-based setting, while controlling for differences in gender and ability. This beneficial impact of team learning on performance was not found for other courses (in which team learning was not implemented), leading to the conclusion that team learning offers an appropriate learning method at the university level for a first-year course. Implications for student learning, faculty members, and institutional policy are discussed.     

Cotton Island: Students’ Learning Motivation Using a Virtual World

As technology advances, it is important for teachers to seamlessly integrate technology into their innovative teaching techniques. Using virtual worlds is one alternative to traditional teaching methods that can provide rich learning experiences. The purpose of this article is twofold: (a) to present Cotton Island, an avatar‐based 3‐D virtual learning environment in Second Life and (b) to evaluate students’ learning motivation in using Cotton Island as a learning tool. Cotton Island was designed with unique navigational features to provide access to rich resources and educational activities that improve students’ knowledge of cotton. Based on the ARCS (attention, relevance, confidence, and satisfaction) model, this study assesses students’ learning motivation when using Cotton Island as a learning tool, and whether students had a positive learning outcome consistent with the instructors’ goal of knowledge improvement. The results show that students had a positive experience in terms of learning motivation and knowledge improvement.     

An alternative way of responding to powerful ideas: notes to accompany the poem entitled ‘Five Principles of Quality in Narratives of Action Research’

The author examines the development of her thinking in regard to the value, the purposes, the process and the outcomes of teaching an undergraduate course in action research for the past 4 years. The emergent understandings were informed by recurrent hermeneutic cycles of interpretative readings of the formal written and oral feedback conducted with the students at the end of each year, the students’ final action research projects submitted at the end of each course and personal field notes kept in journal writing. These sources have yielded rich longitudinal data that sheds light on the impact of a course for the learning of both its participants and the course professor. The article focuses on the actions that the author has undertaken in the design and implementation of the course as a result of her learning or on how action research ‘of a second order’ has informed the structure of ‘first order’ action research. The exploration has led the author to important insights regarding her role as course professor, issues of pedagogy, reflection, process and products of learning as they play out in an action research course at undergraduate level.     

Pedagogical intersectionality: exploring content,technology, and student-centered learning through a problem based/project based approach

ABSTRACT

A narrative case study exploring the course design and implementation of a capstone undergraduate course for future teachers taught with a lens of pedagogical intersectionality, an integration of K-12 history-social science content, advocating for students, and technology. Four undergraduate students’ perspectives on the taught concepts of culturally sustaining pedagogies, universal design for learning and social justice through multimodal approaches resulting in the creation and facilitation of a digital one-day lesson (DODL) that incorporates course tenets and use of technology. Data was collected from course surveys, reflections, DODL lesson plan, and DODL Post microteaching reflections. Themes generated from the data sources were personal learning experiences, cultural respect and acknowledgement, pedagogical growing pains, fatigue, and synthesis occurring in DODL. Collaborators responded to student comments and reflected on course design and goals to foster independent learning of course tenets. Future research will involve additional analysis of subsequent sections of the course based on feedback and reflective modifications learned through this project.

Learning to see the familiar: Technological assemblages in a higher education (non)classroom setting

If an objective of public higher education is to engage with a diversity of communities, then coursework should be less insulated within classrooms. This work describes and analyzes a university course design that supports undergraduate students to experience learning as relational and transformational via Site Visits within various communities. We focus on “technological assemblages” as a way to understand students’ reorientation to the process and purpose of learning (and teaching). We analyze experiences within the course as moments of disorientation, reassembly and stabilization in which students use their mobile devices, bodies and interactions-in-place to understand familiar locations as socially and historically contingent sites of learning (and teaching). We argue that this instructional model does important work of putting students at the nexus of building relationships between the university and other community settings around the city.
