Computer Programming Goes Back to School

Authors:
  • Digital Promise

Abstract and Figures

We are witnessing a remarkable comeback of programming. Current initiatives to promote computational thinking and to broaden participation in computing signal a renewed interest to bring programming back into K-12 schools and help develop children as producers and not simply consumers of digital media. This essay explores the re-emergence of programming in K-12 schools, addressing three questions in particular: First, what is the role of programming in facilitating children’s learning with digital media? Second, how can schools play a more prominent role in supporting such coded production as a veritable new literacy for the 21st century? Third, what are some of the systemic equity issues of access and participation that will need to be addressed? Given these questions facing schools as well as the wider economic viability of this country, it is crucial that we understand the importance of programming as a means to process and communicate information, how it relates to developing minds through computational thinking, and why computational participation as an extension of such thinking represents our best chance to teach programming in schools.

W
e are witnessing a remarkable comeback of computer programming
in schools. In the 1980s, many schools featured Basic, Logo, or Pas-
cal programming computer labs that students typically visited once
a week as an introduction to the discipline. But, by the mid-1990s,
schools had largely turned away from programming. In large part,
such decline stemmed from a lack of subject-matter integration and
a dearth of qualifi ed instructors. Yet there was also the question of purpose. With the rise
of preassembled multimedia packages via glossy CD-ROMs over the 1990s, who wanted
to toil over syntax typos and debugging problems by creating these applications oneself?
This question alone seemingly negated the need to learn programming in school, com-
pounded by the excitement generated by the Internet. Schools started teaching students
how to best surf the web rather than how to delve into it and understand how it actually

other and the greater whole, and then devise algo-
rithms to arrive at an automated solution. Computa-
tional thinking isn’t limited to mathematics and the
sciences but also applies to the humanities in fields
such as journalism and literature.
Thinking like a computer scientist has the poten-
tial to better articulate and advance other academic
disciplines. But how is computational thinking
present and relevant in everyday life? Wing pro-
vides several examples. Consider cleaning up and
sorting Lego brick pieces. If a child sorts the pieces
as “all rectangular thick blocks in one bin,“all thin
ones in another,” and so on, computer scientists
would call this hashing. Of course, most children
(and adults) clean up heaps of Legos simply by just
dumping them in one big bucket. But imagine if the
child wanted to build a bigger project with Legos
and needed to construct the project by selecting
particular pieces in a set sequence. Looking through
a large pile of Lego bricks each and every time
would take far longer than looking through bricks
organized by size, shape, and even color. Establish-
ing these categories would reduce search time and
let the builder concentrate on what he or she wanted
to do in the first place: build, not search. That would
be especially helpful when building more ambitious
and precise structures.
Wing’s definition of computational thinking pro-
voked a wide-ranging response among computer sci-
entists and educators concerning what qualifies as
digital literacy. What does computational thinking
contribute to reasoning and communicating in an
ever-increasingly digital world? To what extent do
works. Schools largely forgot about programming,
some deeming it entirely unnecessary and others la-
beling it too difficult to teach and learn.
But this is changing. In the past five years, we’ve
seen a newfound interest in bringing back learning
and teaching programming on all K-12 levels. But
it’s digitally based youth cultures, not schools, lead-
ing this revival (Kafai & Peppler, 2011). Computers
seem to be accessible everywhere, particularly out-
side school, where children and youth are innovat-
ing with technology often with hand-held devices
to create their own video games, interactive art
projects, and even their own programmable clothes
through electronic textiles. What’s more, the same
computers on which they create these items connect
them to wider networks of other young users who
share common interests and a similar commitment
to connecting through making.
Schools may very well take a page from these
informal communities of creative production and
networked participation. After all, despite this
surge of interconnected youth communities, very
few youth are using their smart devices laptop,
iPad, iPhone, or Droid for something other than
the mass consumption of commercial media. These
digital natives may be able to technically manipu-
late the latest devices, but their capacity to wield
such devices critically, creatively, and selectively is
decidedly less potent.
What then is the role of programming in facilitat-
ing more productive use of technology? And what is
the role of schools in introducing programming to a
wider array of youth, particularly given schools’ own
aborted attempts to teach coding in the past? How
will schools address challenges of diversity and eq-
uity so prevalent in computing culture? Given these
questions facing education as well as the economic
viability of this country, we must first understand
what computational thinking is, how we can teach
it, and why the computational participation of online
communities and traditional schools together offers
new opportunities to engage students.
What is computational thinking?
In 2006, Carnegie Mellon professor Jeannette
Wing defined computational thinking as all “aspects
of designing systems, solving problems, and under-
standing human behaviors” (2006, p. 6). Wing ar-
gued that understanding the world computationally
gives a particular lens to understanding problems
and contributing to their solutions. Computational
thinking while often strictly associated with com-
puter science — actually is better understood as ex-
tending computer science principles to other disci-
plines in order to help break down the elements of
any problem, determine their relationship to each

#1. A shift from code to applications.
Rather than coding exercises for learning about
algorithms and data structures, children now learn
programming to create specifi c applications, be
they video games or interactive stories. They are
engaged by the potential to create something real
and tangible that can be shared with others, con-
verting the learning of programming — at least ini-
tially — from the study of an abstract discipline to
a way of making and being in the world digitally.
#2. A shift from tools to communities.
Happily, the past decade has seen the develop-
ment of many admirable introductory program-
ming languages that have made coding a more in-
tuitive, personal process. Scratch (http://scratch.
mit.edu) and Alice (http://alice.org) are two pri-
mary examples. But developers are realizing that
tools alone are not enough. Every tool needs an
audience and the opportunity to bring like-minded
creators together via the Internet. Accordingly,
tools like Scratch and Alice now have extensive
online communities of millions of young users. The
latest version of Scratch — version 2.0 released
this past spring — actually now exists entirely
online so children can program and share from a
single web site, tacitly highlighting the fact that the
community of practice effectively has become the
key tool for learning to code.
#3. A shift from creating “from scratch” to
creating via “remix.”
Programming is no longer an individual activity in
which source code is hidden and closely guarded.
In the spirit of the open-source movement, there
is an increasing push to share one’s underlying
code and encourage participants to sample oth-
ers’ creations for the sake of adjusting and add-
ing to them. With the idea that such openness
heightens the potential for innovation, young us-
ers embrace sampling and sharing more freely,
challenging the traditional top-down paradigm
characteristic of computer science and of schools
in general.
Broadly speaking, we view the three aforemen-
tioned shifts as a social turn, moving from a pre-
dominantly individualistic view of technology to one
that includes a greater focus on the underlying socio-
logical and cultural dimensions in learning program-
ming and reconceptualizing computational thinking
as computational participation.
schools encourage systematic problem solving across
disciplines, breaking down problems and processes
to determine relationships before reassembling?
These aren’t necessarily new questions for schools
(Grover & Pea, 2013). Although computers have
been in schools for 30 years, computational thinking
hasn’t become part of the curriculum. Teaching word
processing and how to create PowerPoint presenta-
tions don’t engage students in the deeper analysis
needed to think more creatively and critically (Col-
lins & Halverson, 2009). Most youth have no or very
little conception of computer science as a discipline
or how it could apply to their daily lives. In short, stu-
dents need to know not only more about computer
science but what it ultimately means to think more
systematically in order to more effi ciently solve all
types of problems.
Teaching computational thinking
So what could computational thinking look like
in schools? How could we teach it? The defi nition of
computational thinking as designing systems, solv-
ing problems, and understanding human behaviors
admittedly provides quite a broad berth here. Sev-
eral professional groups like the Computer Science
Teachers Association and nonprofi ts like Shodor
have developed academic standards and instructional
activities to make computational thinking more ac-
cessible for K-12 education. Programming has in-
variably played a role in all proposed curricula. Yet
while programming gures prominently, no single
programming language is deemed best by all pro-
ponents. Whether the language is Java/Java Script,
Python, C/ C++, HTML or introductory languages
like Scratch and Alice, teaching the underlying con-
cepts conveyed by the language — not the language
itself — is what’s relevant.
So who is to say that teaching programming in
these languages will have any greater success than
what we witnessed in the 1980s with Logo’s and Pas-
cal’s relatively brief foray into schools?
The answer, we argue, is that children have al-
ready been using code to create and share. Over
the past decade, a plethora of youth-generated web
sites have emerged committed to making and shar-
ing programmable media online, be it video games,
interactive art projects, or digital stories. Inher-
ently do-it-yourself (DIY) in nature, web sites such
as Newgrounds, Planet Kodu, Scratch Online, and
Looking Glass (to name a few) encourage youth pro-
gramming not so much as a learned discipline but
as opportunities to create and share online. Within
this DIY ethos of individual endeavor mixed with
group feedback and collaboration, we see three key
shifts in how youth are now learning computer pro-
gramming:

test takers, yet only 21% of those who took the
AP computer science exam in 2011 were female,
and only 29 of the test takers nationwide that year
were black less than 1% of the total.
In the 1990s and even in the early 2000s, these
longstanding inequities were widely attributed to
the digital divide. Much energy in the 1990s focused
on providing access to computers, not curricula or
pedagogy, with initiatives such as Net Day dedi-
cated entirely to bringing computers into schools
and connecting them to the Internet. Although such
initiatives did some good addressing the access issue,
there remained what media scholar Henry Jenkins
(2006) called the “participation gap” when it came
to children’s usage of digital media in creative and
critical ways.
Debunking the notion that access alone would
address the equity issue, technology educator Mark
Warschauer and Tina Matuchniak (2010) compared
two schools with the same number of computers but
in starkly different neighborhoods in terms of so-
cioeconomics. While students had equal access to
computers in both schools, what was taught and what
students learned in school differed greatly. Students
in the upper socioeconomic neighborhood learned
to work creatively and collaboratively with comput-
ers, at times even programming, while students in
the low-income community were groomed for word
processing and simply learning how to technically
operate the machinery.
Participation in computing is not only about hav-
ing access but also having quality curricula and peda-
gogy. Such quality can occur when computer pro-
gramming allows children to produce, collaborate,
and repurpose content that is personally meaningful.
Focusing on computational thinking would remedy
the lack of engaging curricula in K-12 technology
courses and teach children the concepts and skills
to solve problems algorithmically. Computational
participation meanwhile focuses on the pedagogical
practices and perspectives needed to meaningfully
contribute in wider social networks, including but
not limited to schooling. It is here, within the wider
Getting to computational participation
Who is actually participating computationally is
a whole other story. The three shifts above are hap-
pening largely outside K-12 schools. Within schools,
computer science education remains resolutely top
down, focusing on instilling abstract principles be-
fore any direct application occurs. Within upper-
level high school courses, such as Computer Science
Principles, leading with abstraction is understand-
able given the breadth of topics to be covered. But the
near total lack of computational participation in any
earlier, introductory technology-based coursework
means few students are even considering computer
science principles, much less encountering com-
puter science in their K-12 education.
The numbers support this. Only 2,100 of some
42,000 high schools in the U.S. offer an AP com-
puter science course (College Board, 2012). The
number of introductory computer science courses
has decreased by 17% since 2005. Such a drop
is quite literally inexcusable given the Bureau of
Labor Statistics’ (2012) consistent listing of com-
puter science-related jobs among the fastest grow-
ing professions in the country with over 4 million
new positions expected by 2020. Gender and racial
disparity in computer science represents another
signicant hurdle. Women make up 56% of all AP

outweighs group dynamic and collaborative effort
in terms of academic achievement. Web 2.0 has
taught us the importance of collaboration in facili-
tating more creative and cost-effective solutions to
problems. Access to participation and collaboration
in communities of programming is key to learning
fundamental concepts and practices. Learning to
program is also about learning to participate in the
many digital publics and vice versa.
While only a few of us will become computer sci-
entists who will write the code and design the systems
that undergird much of our daily life, learning, and
leisure, many will encounter the need for some form
of programming at some point in our lives. All of us
are and will remain users of digital technologies and
thus will need at times to be able to critically and
constructively examine designs and decisions that
went into making them. In terms of the magnitude
of what any literacy affords the individual, Paulo
Freire estimated that “reading the word is reading
the world.” We see reading code very much about
reading today’s world in terms of understanding and
having the opportunity to remake it. Schools, their
leaders, teachers, and students play a critical role in
realizing this opportunity.

... Recently, efforts to teach programming skills to K-12 students have become quite popular (Grover & Pea, 2013;Kafai & Burke, 2013;Resnick et al., 2009).

... There is certainly no single answer to this question. The increasing demand for ICT professions necessary for technological and economic growth (Chen et al., 2017;Grover & Pea, 2013), the central role of programming in STEM and computational thinking (Brennan & Resnick, 2012;Lee, 2015;Lye & Koh, 2014;Wilson et al., 2010), its definition as a new skill within 21st-century skills and its contribution to the development of 21st-century skills (Clements & Gullo, 1984;Fessakis et al., 2013;Kafai & Burke, 2013), and its recognition as one of the literacy types of our age (Hagge, 2017) are some of the factors influencing this trend. Through programming, students are exposed to computational thinking, which involves the use of computer concepts such as abstraction, algorithmic thinking, pattern recognition and generalization, and iteration in problemsolving (Brennan & Resnick, 2012). ...
... In the 1990s, there was a decline in interest in programming education (Kafai & Burke, 2013;Moreno-León & Robles, 2016).

The purpose of this study is to adapt the "Computer Programming Self-Efficacy Scale for Computer Literacy Education (CPSES)" developed by Tsai et al. (2019) into Turkish for middle school students and to develop a valid and reliable measurement tool. The participants of the study consisted of 348 eighth grade students. In order to test the factor structures of the adapted scale, the data obtained were analyzed with first and second order factor analysis. The results of the analysis showed that the adapted scale had high reliability, convergent validity and divergent validity. The results of the first-and second-order confirmatory factor analysis showed that both models had good fit values with the data. All 16 items and 5-factor structure (Logical Thinking, Cooperation, Algorithm, Control, Debug) in the original scale were retained in the Turkish scale. As a result, it was concluded that the Computer Programming Self-Efficacy Scale for Computer Literacy Education (CPSES) is a valid and reliable measurement tool in Turkish culture.
... Desde esta óptica, Wing (2011) enfatiza que el principal proceso del pensamiento computacional es la abstracción y que dicho proceso es de gran utilidad para definir patrones, iniciarse en la generalización a partir de contextos específicos y modelizar, poniendo el acento en la promoción de estas habilidades de manera transversal desde las primeras edades. Este tipo de pensamiento, que proviene de la informática, implica conceptos como bucles, condiciones y algoritmos; pero también prácticas, como la abstracción, comprobación y depuración, que también se encuentran presentes en otras disciplinas (e.g., las matemáticas, la biología, las ciencias sociales, el arte, la ingeniería...) (Kafai & Burke, 2013). Por esta razón, diversos autores apuestan por la introducción del pensamiento computacional desde la educación infantil y más allá del contexto informático, siguiendo la idea de que para incorporar el pensamiento computacional es necesario un enfoque práctico, basado en una conceptualización operativa (Alsina & Stephenson, 2011) y multidisciplinar (e.g., Bråting & Kilhamn, 2021;Polanco Padrón et al., 2020;Ye et al., 2023). ...

To meet the needs of 21st-century learners in today’s classrooms, it is needed that teachers be familiar with programming and computational thinking. Particularly, subject-area pre-service teachers should be exposed to programming instruction in their teacher education programs. This case study including three participants aims to explore the process of pre-service teachers’ learning of programming while completing CT-oriented tasks through observations and interviews in a 14-week educational technology course at a public university in Turkey. The findings demonstrate that pre-service teachers, being novice programmers, prefer contextualized, structured and visually well-designed programming tasks. They use various strategies to face challenges, and the effort they put into dealing with these challenges enables them to produce higher-quality programs. Accordingly, implications for further research are also discussed in this study.

The so-called fourth industrial revolution, based upon widespread use of data analytics, rapid refinements in artificial intelligence and its applications, and near universal access to high-speed Internet supporting cloud storages, has created economic and social conditions that require an increasing supply of ICT skilled workers. If one of the important purposes of school mathematics is to help young people to understand these conditions and prepare them to take part in this revolution in their future work, then, among other issues, computational/ algorithmic thinking (CT/AT), which underpins the above conditions, can be expected to assume a more visible place in the mathematics curriculum of the future. This chapter summarises recent research on CT/AT and outlines current trends, challenges and possible directions for the future of school mathematics curriculum that should foster developing CT/AT.

Traditionally, educational researchers and practitioners have focused on the development of youths’ critical understanding of media as a key aspect of new media literacies. The 21st Century media landscape suggests an extension of this traditional notion of literacy – an extension that sees creative designs, ethical considerations, and technical skills as part of youth's expressive and intellectual engagement with media as participatory competencies. These engagements with media are also part of a growing Do-It-Yourself, or DIY, movement involving arts, crafts, and new technologies. The purpose of this chapter is to provide a framework and a language for understanding the multiple DIY practices in which youth engage while producing media. In the review, we will first provide a historical overview of the shifting perspectives of two related fields—new media literacies and computer literacy —before outlining the general trends in DIY media cultures that see youth moving towards becoming content creators. We then introduce how a single framework allows us to consider different participatory competencies in DIY under one umbrella. Special attention will be given to the digital practices of remixing, reworking, and repurposing popular media among disadvantaged youth. We will conclude with considerations of equity, access, and participation in after-school settings and possible implications for K-12 education. Drawing upon international research, Review of Research in Education, Volume 35 examines the interplay between youth cultures and educational practices. Although the articles describe youth practices across a range of settings, a central theme is how gender, class, race, and national identity mediate both adult perceptions of youth and youths’ experiences of schooling.

Various aspects of computational thinking, which builds on the power and limits of computing processes, whether they are executed by a human or by a machine, are discussed. Computational methods and models are helping to solve problems, design systems, and understand human behavior, by drawing on concepts fundamental to computer science (CS). Computational thinking (CT) is using abstraction and decomposition when attacking a large complex task or designing a large complex systems. CT is the way of thinking in terms of prevention, protection, and recovery from worst-case scenarios through redundancy, damage containment, and error correction. CT is using heuristic reasoning to discover a solution and using massive amount of data to speed up computation. CT is a futuristic vision to guide computer science educators, researchers, and practitioners to change society's image of the computer science field.

The Common Core State Standards (CCSS) set a controversial aspirational, quantitative trajectory for text complexity exposure for readers throughout the grades, aiming for all high school graduates to be able to independently read complex college and workplace texts. However, the trajectory standard is presented without reference to how the grade-by-grade complexity ranges were determined or rationalized, and little guidance is provided for educators to know how to apply the flexible quantitative text exposure standard in their local contexts. We extend and elaborate the CCSS presentation and discussion, proposing that decisions about shifting quantitative text complexity levels in schools requires more than implementation of a single, static standard. A rigorous two-part analytical strategy for decision making surrounding the quantitative trajectory standard is proposed, a strategy that can be used by state policy makers, district officials, and educators in general. First, borrowing methods from student growth modeling, we illustrate an analytical method for creation of multiple trajectories that can lead to the CCSS end-of-high-school target for text complexity exposure, resulting in trajectories that place greater burden for shifting text complexity levels on students in different grades. Second, we submit that knowledge of the multiple possibilities, in conjunction with a set of guiding principles for decision making, can support educators and policy makers in critiquing and using the CCSS quantitative standard for text complexity exposure to establish particular expectations for quantitative text complexity exposure for particular students in situ.

Jeannette Wing’s influential article on computational thinking 6 years ago argued for adding this new competency to every child’s analytical ability as a vital ingredient of science, technology, engineering, and mathematics (STEM) learning. What is computational thinking? Why did this article resonate with so many and serve as a rallying cry for educators, education researchers, and policy makers? How have they interpreted Wing’s definition, and what advances have been made since Wing’s article was published? This article frames the current state of discourse on computational thinking in K–12 education by examining mostly recently published academic literature that uses Wing’s article as a springboard, identifies gaps in research, and articulates priorities for future inquiries.
Article
This paper drew upon a recent book (Rethinking Education in the Age of Technology) to summarize a number of prospects and challenges arising from the appropriation of digital technology into learning and educational practice. Tensions between traditional models of schooling and the affordances of digital media were noted, while the promise of these technologies for shaping a new system of education was reviewed. It was argued that new technology brings radical opportunities but also significant challenges. The urgency of seeking a coherent model for the future of education in a technological age was stressed.
