Two for One: Squeezing Human-Computer Interaction and Software Engineering into a Core Computer Science Course

The final report of the Joint Task Force on Computing Curricula (CC2001) suggests that an updated computer science curricula must reflect the broadening nature of our discipline. Two areas that are included in the CC2001 are software engineering (SE) and human-computer interaction (HCI). While the first inclination might be to incorporate HCI concepts into a traditional SE course, we propose a different approach. This paper outlines a project-oriented HCI course in which we are able to emphasize some SE notions in the context of HCI concepts. Our course is also a maturation class for our students because they are exposed to a number of non-programming computer science activities, including project specification, software and interface design, user testing, prototyping and use of guidelines. We include an overview of course content that illustrates our approach. We also describe our coverage of specific CC2001 knowledge units and provide some feedback data for our course.     

Introducing MOOC-like methodologies in a face-to-face undergraduate course: a detailed case study

During the last years online education, in particular Massive Open Online Courses (MOOCs), has contributed to spread and popularize educational methodologies such as peer-review, automatic assessment, self-paced courses, self-evaluation, etc. Although these techniques can benefit face-to-face courses, most of them are not yet widely used in these courses. In this paper we present our experience integrating MOOC-like techniques in a face-to-face first year undergraduate course. We describe the academic and institutional context of the project, how we designed and adapted the methodologies to our face-to-face course, the software tools that we have used and developed to support and integrate such methodologies and, finally, we discuss some lessons learned from the experience that can be useful to potential users of these methodologies in face-to-face courses.

Then, we share the intellectual and logistical hurdles we have experienced and offer advice on how to overcome them for those planning to teach a seminar on prisons. Included is specific advice on how to successfully integrate prison tours as an experiential learning tool.     

Game Building with Complex-Valued Functions

Abstract

In this paper, we describe how we integrated complex analysis into the second semester of a geometry course designed for preservice secondary mathematics teachers. As part of this inquiry-based course, the preservice teachers incorporated their geometric understanding of the arithmetic of complex numbers and complex-valued functions to create a game using Geometer’s Sketchpad. We detail a game created by a pair of preservice teachers that exemplifies their creativity and knowledge of complex-valued functions. Given inquiry-based courses have inherent challenges we also present projects that were not as exemplary.

A culturally relevant teaching course: Reflecting pre‐service teachers’ thinking

As professors of Culturally Relevant Teaching, we seek to expand pre‐service teachers’ understanding of cultures through critical examination of personal cultural backgrounds, as well as, of those diverse groups who historically have experienced oppression in US society and its educational system. We share the story of how we develop and implement the course, setting it in the context of our teaching for a social justice‐oriented teacher education program in a predominantly White, rural, state university college. We indicate the literature from which we developed the course content and its activities; we analyze pre‐service teachers’ awareness of their cultural identities; and, describe the implications of this knowledge for teaching as reflected in the cultural autobiographies and narratives pre‐service students write at the beginning and end of the course. We hope this study will be helpful to other multicultural educators implementing similar courses.     

Mathematics for teaching and deep subject knowledge: voices of Mathematics Enhancement Course students in England

This article reports an investigation into how students of a mathematics course for prospective secondary mathematics teachers in England talk about the notion of ‘understanding mathematics in depth’, which was an explicit goal of the course. We interviewed eighteen students of the course. Through our social practice frame and in the light of a review of the literature on mathematical knowledge for teaching, we describe three themes that weave through the students’ talk: reasoning, connectedness and being mathematical. We argue that these themes illuminate privileged messages in the course, as well as the boundary and relationship between mathematical and pedagogic content knowledge in secondary mathematics teacher education practice.     

Breaking with Tradition: Using Rapid Prototyping In The Software Engineering Course

One approach to the development of software, which has received considerable attention in the software engineering literature, is rapid prototyping. We describe the rapid prototyping methodology and discuss some of its advantages and disadvantages. We then focus on the use of rapid prototyping in the project component of the typical undergraduate software engineering course. Several approaches to prototyping are described, along with various automated tools that support prototyping. Our experiences with prototyping in our undergraduate software engineering course are described, and we draw a number of conclusions vis a vis the use of prototyping.     

The development of a conceptual framework and tools to assess undergraduates' principled use of models in cellular biology

Recent science education reform has been marked by a shift away from a focus on facts toward deep, rich, conceptual understanding. This requires assessment that also focuses on conceptual understanding rather than recall of facts. This study outlines our development of a new assessment framework and tool-a taxonomy- which, unlike existing frameworks and tools, is grounded firmly in a framework that considers the critical role that models play in science. It also provides instructors a resource for assessing students' ability to reason about models that are central to the organization of key scientific concepts. We describe preliminary data arising from the application of our tool to exam questions used by instructors of a large-enrollment cell and molecular biology course over a 5-yr period during which time our framework and the assessment tool were increasingly used. Students were increasingly able to describe and manipulate models of the processes and systems being studied in this course as measured by assessment items. However, their ability to apply these models in new contexts did not improve. Finally, we discuss the implications of our results and the future directions for our research.     

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.     

On Consultation and Beginner Educational Psychologists

In this article, we describe some of our purposes and processes when introducing consultation as a comprehensive model of service delivery to course members in their programme of initial professional education. We also note some of the impacts from this model, both in the course modules and the placement experiences. While it is written from the perspective of course tutors, we hope that this account may trigger useful thoughts for readers-about their own initial training, about their current model of practice, about their current professional development or even their current contribution to initial training.

Inverse function: Pre-service teachers’ techniques and meanings

Researchers have argued teachers and students are not developing connected meanings for function inverse, thus calling for a closer examination of teachers’ and students’ inverse function meanings. Responding to this call, we characterize 25 pre-service teachers’ inverse function meanings as inferred from our analysis of clinical interviews. After summarizing relevant research, we describe the methodology and theoretical framework we used to interpret the pre-service teachers’ activities. We then present data highlighting the techniques the pre-service teachers used when responding to tasks that involved analytical and graphical representations of functions and inverse functions in both decontextualized and contextualized situations and discuss our inferences of their meanings based on their activities. We conclude with implications for the teaching and learning of inverse function and areas for future research.     

Beyond the Central Dogma: Model-Based Learning of How Genes Determine Phenotypes

In an introductory biology course, we implemented a learner-centered, model-based pedagogy that frequently engaged students in building conceptual models to explain how genes determine phenotypes. Model-building tasks were incorporated within case studies and aimed at eliciting students’ understanding of 1) the origin of variation in a population and 2) how genes/alleles determine phenotypes. Guided by theory on hierarchical development of systems-thinking skills, we scaffolded instruction and assessment so that students would first focus on articulating isolated relationships between pairs of molecular genetics structures and then integrate these relationships into an explanatory network. We analyzed models students generated on two exams to assess whether students’ learning of molecular genetics progressed along the theoretical hierarchical sequence of systems-thinking skills acquisition. With repeated practice, peer discussion, and instructor feedback over the course of the semester, students’ models became more accurate, better contextualized, and more meaningful. At the end of the semester, however, more than 25% of students still struggled to describe phenotype as an output of protein function. We therefore recommend that 1) practices like modeling, which require connecting genes to phenotypes; and 2) well-developed case studies highlighting proteins and their functions, take center stage in molecular genetics instruction.

Field philosophy: environmental learning and moral development in Isle Royale National Park

We conducted a qualitative analysis of 5 years of student writing data to understand learning and moral development on a field philosophy course in Isle Royale National Park. We were interested in the connection between physical experiences in the natural world and the way students care about or value nonhuman beings, natural systems, and place. Students consistently demonstrated a shift from a dualistic to a more complex understanding of ideas, relationships, and the natural world. This widening perception and moral awareness occurred in tandem with course content learning. In this paper we describe the model that emerged from our data to describe this shift from dualism to complexity – from self-awareness, to social learning, to curriculum engagement, to a wider moral community – and the factors that facilitate each step. We also provide a planning and assessment tool to help other educators begin to observe ethical development and relational growth in their own interdisciplinary environmental field classes.
