3 HS CS curricula are all over the map. Problems Implementing Effective Computer Science Courses at the High School LevelComputer Science is widely confused with Computer Literacy or CTE vocational courses (the use of computers), when it should be thought of as a sister ACADEMIC field to Mathematics.There are no accepted or recognized national or state standards.There is little research on which to judge the effectiveness of pedagogical strategies.The field struggles with a large gender gap and low enrollments of under-represented minority students (URMs).There is a lower level of high school STUDENT INTEREST in and/or ACCESS to Computer Science – by an order of magnitude – as compared to Calculus, Statistics or Biology, as measured by those taking the AP Exam.There is no credible certification process, nor credential training programs, for Computer Science instructors.HS CS curricula are all over the map.
4 Even if we had a standards-based curricula, there exist no standardized assessment mechanisms to determine whether we would be successfully teaching the material to our students.(putting aside the question of whether a pen-and-pencil examination without a computer-based programming portion meaningfully assesses whether students can solve real problems in new contexts)
6 Typical High School Standards: Math vs. CS ACM Model Level II Curricular StandardsStandard 6: The connection between elements of mathematics and computer science, including binary numbers, logic, sets, and functions.What ARE the specificconnections?For what tasks are you using binary numbers, sets, etc.?ACM Model Level III Curricular StandardsTopic 1: Program Design and Problem Solving.14. Iteration.Iteration in what context?Iteration to do which tasks?Iteration to solve what kinds of problems?Algebra I9.0. Students solve a system of two linear equations in two variables algebraically and are able to interpret the answer graphically. Students are able to solve a system of two linear inequalities in two variables and to sketch the solution sets.19. Students know the quadratic formula and are familiar with its proof by completing the square.The math standards are specific concepts and skills detailing how students will demonstrate mastery. The CS standards are general topics.
7 What might a specific CS Standard look like? Iteration through a list (array / arraylist):Students know how to write a loop that uses iteration to:(1) FIND a specific value in a list.(2) REMOVE all items in an arraylist that have a specific value.(3) CALCULATE an AGGREGATE VALUE for items in a list.How do you create High School Standards?There is general agreement that we want at least a two-year sequence for programming.In CS, we use control structures for many specific purposes. For each year, determine (1) what specific concepts and skills we want students to know, and (2) what kinds of problems should they be able to solve using those concepts and skills?When we determine exactly what we want our students to know, then we can devise assessments that will measure whether students have learned those standards.

9 At our schools, CS teachers are often the only people who know – or care – about computer science education.Other teachers (and administrators) are not only ignorant of the possibilities of potential application of CS to their subject matter, they are oftentimes indifferent .This can be a lonely state of affairs.The upside, however, is that this also givesCS instructors a great deal of freedom in what and how they teach.HOWEVER…

11 Broadening the Scope of CS in Course Content A research study1 of differences between men and women CS students at CMU found:Curriculum helps set the tone and, unfortunately, most computer science programs in their early years are narrowly focused on programming and the more technical aspects of the field, with applications and multidisciplinary projects deferred to the very end. This gives beginning students the false message that computer science is "only programming, programming, programming," abstracted away from real world contexts.Feminist educator Sue Rosser , from her investigation of gender and science education, argues that "insuring science and technology are considered in their social context…may be the most important change that can be made in science teaching for all people, both male and female" (p.72.) Computer science professor Dianne Martin , in her article In Search of Gender Free Paradigms for Computer Science Education, discusses "a premise for the gender bias in computer science: the existing educational paradigm that separates studies of science, math, and computer science from studies of the humanities, starting in the secondary schools." She speculates that an integrated approach to computer science would attract more women students, and that "greater attention [should be paid] to values, human issues, and social impact as well as to the mathematical and theoretical foundations of computer science."1.Caring About Connections: Gender and Computing (1997). Jane Margolis, Allan Fisher and Faye Miller.
12 enrollment numbers of women (and URMs) in CS courses. 1. The pervasiveness of computer games in recent decades, as well as instructors' embrace of gaming as a central curricular theme for attracting young people, reinforces a badly skewed perception of CS as both (a) an arena of hyper-competition and (b) a field having limited application to areas outside of CS itself. If an academic field can be said to exist within a context, then:The context of CS is popularly believed to includea very narrow slice of human knowledge and activities.2. Consider that, at the undergraduate level, women are either overrepresented or have high representation in the fields of Environmental Science (a subfield of the geosciences), the Life Sciences, Psychology, the Social Sciences, Education and the Arts. Were CS curricula to add content whose contexts included, but were not limited to, these subjects, it would more fairly represent the influence and scope of CS in matters of potential interest to a broader swath of students.Hypothesis #1: Interdisciplinary CS curricula that emphasize connections with academic subjects where the representation of women is more balanced might increaseenrollment numbers of women (and URMs) in CS courses.

15 If Prof. Dianne Martin were correct, namely that separating the curriculum into discrete academic subjects - with a major demarcation between the STEM fields and the humanities – contributes to gender inequities, then one would expect gender disparities to show up in all STEM areas across the board. From the 2010 AP Exam data shown below, this is not the case.AP EXAM (2010)N% FemaleBiology172,51257.8%Calculus AB245,86748.4%Calculus BC78,99840.5%Chemistry115,07746.7%Computer Science A20,12019.0%Economics – Macro83,14645.0%Economics – Micro51,60142.9%Environmental Science86,65055.4%Physics B67,31235.0%Physics C E&M14,19123.0%Physics C Mechanics31,97326.2%Psychology177,70857.3%Statistics129,89950.4%

18 What are those subject areas doing that CS is NOT doing? … or …. So one question that arises is:What are those subject areas doingthat CS is NOT doing? … or ….What is CS doing that is TURNING OFF STUDENTS ?But the data also suggest a different strategy for addressing gender and ethnic inequities:If we increase the participation of ALL students in Computer Science, will that by itselfbring about an increase inthe percentages of females (and URMs)?In deciding whether to pursue this line of attack, it may be instructive to look at the narrowing/elimination of the gender gap in mathematics and try to understand why that area has experienced an improvement in gender equity.
19 Women and Math, the Gender Gap Bridged Social equality frees women to match menBased on the Research of Luigi Guiso, Ferdinando Monte, Paola Sapienza And Luigi ZingalesJune 2008, Kellogg School of Management, Northwestern UniversityRegardless of which measure of gender equality they used, Sapienza and her colleagues found that improved social conditions for women were related to improved math performance by girls. For example, the math gender gap almost disappeared in Sweden (GGI = 0.81), while girls scored nearly 23 points below boys in math in Turkey (GGI = 0.59). Not only did average girls’ scores improve as equality improved, but the number of girls reaching the highest levels of performance also increased. In Iceland, for example, there were 117 girls for every 100 boys among the top 1 percent of math students.“We establish that in some countries the gender gap in math disappears. But there’s a big tension. Is it emancipation of women, or is it something else?” said Sapienza. “One possible explanation is wealth.”
20 To learn whether the math gender gap shrank as a result of girls in richer countries performing better than those in poorer countries, the researchers incorporated each country’s gross domestic product (GDP) into their mathematical model. Regardless of national differences in per capita GDP, the relationship between gender equality and the math gap remained. Improved roles for women in society, not simply economic development, predicted more gender-equal achievement in math. For example, Sapienza pointed out, “In some countries like Philippines or Sri Lanka, which aren’t particularly wealthy, women are fairly emancipated. On the contrary, some wealthy countries, like Italy, are among the less gender equal societies.”Though these findings are fascinating and extremely important, they raise as many questions as they answer. It is not yet clear how important education is compared with other social features. “The big, important question is, ‘What’s the mechanism?’ ” said Sapienza. “What are these northern European countries doing so that there is no gap? Is it happening through role modeling? The kinds of jobs women get? Is it more acceptable for a woman to be a physicist in Sweden than in other countries? We simply do not know.”
21 Summary of CS at the High School Level CS has one of the lowest enrollments of the STEM fields. (College Board data)In the STEM areas, there is a positive correlation between absolute numbers / enrollments of all students and gender equity. (College Board data)On a country-by-country basis, there is a positive correlation between the narrowing of the gender gap in mathematics achievement with higher levels of gender equity in society as a whole. (Sapienza et al.)A gender gap no longer exists in many STEM subjects. (College Board data)CS curricula are widely taught without significant connections to other academic disciplines, and abstracted away from real world contexts. (Margolis et al.)The most important areas of real world application of CS are widely believed to be limited to gaming, the Internet, social networking, and hand-held devices. That is:The popular perception is that the SCOPE of CS is NARROW.
22 InferencesThe fact that girls participate in equal or better numbers in several STEM subjects indicates that the social conditions already exist in the U.S. for girls to participate and succeed in Computer Science on a par with boys.Increasing the absolute numbers of all students in CS may have a positive effect on gender equity.Low enrollments may be due to a problem in PR. Low overall enrollment numbers may mean that all students – not just girls and URMs – see little value to CS in the real world.REVISED HYPOTHESIS: Suppose we were to provide MEANINGFUL CONTEXTS in CS curricula connecting Computer Science to other academic subject areas, and human interests and activities. If we devise curricula that connect CS to a FULL spectrum of topics –and strive to include topics that students study in their other classes – in a SERIOUS AND SIGNIFICANT WAY, the absolute numbers of students taking CS courses may increase, and the proportion of females and URMs should also rise.
23 COURSE CONTENTAP Computer Science A and AB are two courses whose basic content has no substantial differences from college courses taught in the 1980s. Although as part of a college sequence, one could make an argument for retaining these courses, few seem to question why one should teach high school students the specific content in these courses.For example, APCS-A requires that students learn certain SORTING algorithms. This content might make sense for students to learn at the beginning of a comprehensive course in algorithms. However, given the breadth of fascinating CS applications that have appeared over the previous decades, one would be hard-pressed to make a case as to WHY high school students should be learning this [relatively drab and boring] material, especially in isolation and with no further follow-up.While the course content in subject areas such as Biology have kept pace with new discoveries, CS content seems to be stuck.
24 PEDAGOGYIn CS Education, new student software tools appear at a relatively fast clip, e.g. Alice, Scratch, BYOB/Snap, but little collective thought is focused on how best to use these tools. In high school educational settings, these tools are primarily used to engage students using story-telling or games, and lesson content is often shallow.When curricula are developed for these tools, they employ the SAME PEDAGOGICAL PARADIGM that has been used for the last 30 years. That is, students learn CS constructs and control structures, then practice using these concepts in short problems divorced from substantial real-world applications.Moreover, curricula fail to explore and fully exploit in new ways the possibilities that these tools offer. The strength of Alice and BYOB is their ability to visually model real-world problems and clarify the algorithms used for their solution. Using Alice, students can build a replica of the solar system to calculate the trajectory of a space mission to Mars, or construct biologically important molecules to illustrate disease in BYOB. Tasks such as skaters performing pirouettes around holes in the ice tend to trivialize CS in pursuit of a perceived trade-off for engagement at the expense of rigor (though this instructor found students quickly tiring of make-believe scenarios.)
25 PEDAGOGYAn alternative to a CS-concepts-first curriculum is one whose units revolve around a CENTRAL PROBLEM which students solve over a period of several weeks using whatever CS tools are needed.In mathematics, IMP1 (Interactive Mathematics Program), created with the support of NSF in the 1990s, is such a curriculum. IMP is a 4-year program of problem-based mathematics that replaces the traditional Algebra I-Geometry-Algebra II/Trigonometry-Precalculus sequence."IMP units are generally structured around a complex central problem. Although each unit has a specific mathematical focus, other topics are brought in as needed to solve the central problem, rather than narrowly restricting the mathematical content. Ideas that are developed in one unit are usually revisited and deepened in one or more later units."For example, although the real-world application is a stretch, the complex problem posited by IMP’s High Dive (Year 3) unit has students calculate at what point a circus performer on a turning Ferris wheel should dive so as to land in a tub of water on a moving cart.1(Unit Summary)
26 IMP: Interactive Mathematics Program The HIGH DIVE problem. Students extend right-triangle trigonometric functions to the circular functions, learn about the graphs of the sine and cosine functions, study polar coordinates, inverse trigonometric functions, and the Pythagorean identity, and study the physics of falling objects.
27 Guidelines for Interdisciplinary Problem-Based CS Curricula 1. Computer Science’s natural relationship to other disciplines is known as Software Engineering, a field which uses programming and CS concepts, along with expert knowledge of specific target topics, to model and solve societal problems and needs. The topic areas for which software engineering methods might be applied may themselves be within the realm of CS, however the vast majority are not.2. Each unit lasts several weeks and revolves around solving a central problem in the target topic area. A software solution evolves in a scaffolded way, utilizing whatever CS concepts and control structures may be required. Various strategies are attempted at each step to solve problems, discussing their advantages and disadvantages. Drill-like short practice problems (in the spirit of Codingbat.com) are used to integrate CS concepts and skills whenever they are introduced or used in new ways.3. One way instructors can foster connections is by having students create small scale versions of engaging and complex real world applications. With little imagination, students should be able to envision logical extensions of their projects to the already existing and more complex programs from which student exercises were inspired.
28 Guidelines for Interdisciplinary Problem-Based CS Curricula 4. In order to solve a unit’s central problem, students may need to review or be introduced to new concepts in geometry, trigonometry, biology, physics and so forth. This reflects typical considerations that software engineers encounter in their day-to-day work, i.e. programmers must not only be proficient in their own field, but must have knowledge of the specific (non-CS) systems they are modeling in order to write accurate, robust and logically organized programs. The pedagogic advantage for students in needing more than token exposure to other academic fields to solve a central problem is that the multiple CONTEXTS allow students more handles to recall and integrate what they learn.5. Units also place the central problem within a SOCIAL or HISTORICAL CONTEXT. This helps students to not only understand how to solve the central problem, but provides them an explanation why solving the central problem is important in the first place. These so-called back-stories may utilize Literature, Theatre, History, Social Studies, Economics, Film and Art in making those connections. This is NOT done in a tokenistic way. This part of the unit may take up to several days and in some cases more than a week of class time. Students are assessed on this material in a serious way, such as writing an essay in response to a choice of several prompts. One goal should be for instructors to make connections to topics students learn in other academic courses.
