Epistemological, Psychological, Neurosciences, and Cognitive Essence of Computational Thinking

Publications

The construct of computational thinking (CT) was popularized a decade ago as an “attitude and skillset” for everyone. However, since it is equated with thinking by computer scientists, the teaching of these skills poses many challenges at K-12 because of their reliance on the use of electronic computers and programming concepts that are often found too abstract and difficult by young students. This article links CT – i.e., thinking generated and facilitated by a computational device – to our typical fundamental cognitive processes by using a model of mind that is aligned with research in

The Essence of Computational Thinking

Publications

A decade of discourse to capture the essence of computational thinking has resulted in a broad set of skills whose teaching continue to pose challenges because of the reliance on the use of electronic computers and programming concepts. This article not only links computational thinking skills to fundamental cognitive competencies but also describes pedagogical tools that have proven effective in teaching them at early ages.

Barcoding Life's Matrix: Engaging Students as Citizen Scientists in the Barcode of Life Initiative

Publications

Discovery-based science education represents a structured alternative to open-ended forms of hands-on inquiry that is now being employed in a number of secondary and post-secondary settings to address science education reform agendas. In the context of molecular life science education, this particular form of instruction links domain knowledge, laboratory methods, and bioinformatics (or computational biology) within the framework of a complete and integrated analytic workflow that culminates in a tangible scientific output and a bona fide contribution to a particular body of scientific

Growing Plants and Scientists: Fostering Positive Attitudes toward Science among All Participants in an Afterschool Hydroponics Program

Publications

This study examines an out-of-school time program targeting elementary-aged youth from populations that are typically underrepresented in science fields (primarily African-American, Hispanic, and/or English Language Learner participants). The program aimed to foster positive attitudes toward science among youth by engaging them in growing plants hydroponically (in water without soil). Participants’ attitudes toward science, including anxiety, desire, and self-concept, were examined through pre-post survey data (n = 234) over the course of an afterschool program at three separate sites. Data

Social Justice Driven STEM Learning (STEMJ): A Curricular Framework for Teaching STEM in a Social Justice Driven, Urban, College Access Program

Publications

This article presents the curricular framework for a social justice driven STEM curriculum (i.e., STEMJ) within an out-of-school time program for Boston Public high school students (i.e., College Bound) at Boston College. Starting with a discussion of the authors’ ideological positionality within critical social justice discourses, the authors share how Bronfenbrenner’s (1994) General Ecological Model provides a conceptual framework for operationalizing social justice inquiry with and through STEM. Positioning this curriculum within the College Bound program’s overall design gives readers a

STEM Pathways: Examining Persistence in Rigorous Math and Science Course Taking

Publications

From 2006 to 2012, Florida Statute §1003.4156 required middle school students to complete electronic personal education planners (ePEPs) before promotion to ninth grade. The ePEP helped them identify programs of study and required high school coursework to accomplish their postsecondary education and career goals. During the same period Florida required completion of the ePEP, Florida’s Career and Professional Education Act stimulated a rapid increase in the number of statewide high school career academies. Students with interests in STEM careers created STEM-focused ePEPs and may have

Techno-Social Change Agents: Fostering Activist Dispositions Among Girls of Color

Publications

Discourse about girls and women of color in technology has followed the familiar path of using a single-unit analysis to explain disparity. Consequently, approaches to “motivate” girls of color overemphasize gender and engage in technological fetishization without fully considering how race, gender, class, and technology are co-constituted. Drawing on critical feminist theory, social justice education, and science and technology studies, this essay offers a critique of neoliberal approaches to technology education for girls of color and provides a broad overview of the conceptual catalysts

Traversing a Political Pipeline: An Intersectional and Social Constructionist Approach Toward Technology Education for Girls of Color

Publications

First, this paper argues that applications of SCOT in feminist science and technology studies (STS) have largely focused on analyzing how gender and technology are coproduced, resulting in lack of scholarship that examines the mutually constitutive relationship between technology, gender and other intersecting identity categories, such as race and class. Second, this paper argues that an intersectional view of technology can dismantle the language of objectivity deeply embedded in technological artifacts by revealing how gender, race, and class are integral components of “the social shaping of

Designing and Implementing an Elementary Science After School Field Experience

Publications

Field experiences provide an important opportunity for preservice teachers to observe and practice science instruction. Too often, insufficient time is allotted for elementary science instruction in the formal classroom. This paper outlines the opportunities and lessons learned from an after school field experience where preservice elementary teachers worked in two-person teams with a classroom mentor teacher at local elementary schools and community centers to deliver two science lessons per week during an elementary science methods course. Multiple evidences of success are presented at the

Computing with a Community Focus: Outcomes from an App Inventor Summer Camp for Middle School Students

Publications

This paper describes the design and evaluation of a one-week App Inventor summer camp for middle school students with an explicit focus on addressing local community needs. The community focus of the camp was designed to appeal to a broad range of students. We conducted an in-depth interview study to examine its impact on students' attitudes and perceptions, and supplemented this with results from project evaluation. Our results indicate that students had positive experiences in learning and creating real apps for solving community problems. Focusing on local community needs can also help to
