School Administrators and Educational Technologies: narrowing the divide

ABSTRACT

Technologies that enhance classroom instruction and school administration are widespread. The majority of schools, however, have yet to implement technologies beyond a basic level. Reasons for this reluctance include a lack of funds, teacher beliefs about the role of technology in education, methods of technology allocation and distribution in schools, a lack of understanding of how technologies can accentuate learning and administration, and most importantly, a lack of vision and support from school administrators. To help solve the problem of administrative support, we propose the creation of university courses designed to nourish school technology leaders. Included in this paper is a basic outline for such a course.     

Activity-based learning of statistics: Using practical applications to improve students' learning

Many obstacles are involved in teaching statistics to undergraduates, including high attrition rates, students' anxiety, and a limited ability to grasp difficult concepts. These concerns can be addressed effectively by implementing strategies that require students to be actively engaged in the learning of statistics. First, we discuss how activity-based strategies and information technology can be an effective way to teach a statistics course. Second, we discuss how we changed a statistics course to include activity-based strategies. Finally, we discuss how cooperative learning, as a type of activity-based strategy, can increase students' understanding of statistics.     

Take space,make space: how students use computer science to disrupt and resist marginalization in schools

ABSTRACT

Background and Context

Overlaying Computer Science (CS) courses on top of inequitable schooling systems will not move us toward “CS for All.” This paper prioritizes the perspectives of minoritized students enrolled in high school CS classrooms across a large, urban school district in the Western United States, to help inform how CS can truly be for all.     

Constructing Problems in a Web‐Based Learning Environment

Abstract

This article describes how the World Wide Web was implemented in a graduate course. The interactions that took place among the students and between the students and instructor illustrate how problem‐based learning strategies can be supported by the Web. Of particular note, the course content focused on technology‐based learning, thus students were immersed in an authentic learning environment. The article chronicles the various strategies ? that students implemented to facilitate the problem‐solving process and concludes by way of issues to consider when implementing such strategies within Web‐based learning environments     

The Roles of Technology in Mathematics Education

Abstract

We review literature relevant to using technology in the teaching/learning of mathematics to highlight four roles of effective technology use: (a) promoting cycles of proof; (b) presenting and connecting multiple representations; (c) supporting case-based reasoning; and (d) serving as a tutee. We then discuss how they intersect with good instruction. Finally, we provide specific examples to illustrate how these roles of technology can be used to maintain the focus of a technology course on mathematics.     

The S‐Machine: An Alternative Approach to Teaching Assembler Programming

The demand for assembler language programmers has dropped dramatically over the past 20 years with the advent of structured programming languages and the accessibility of hardware features from high‐level languages. Nevertheless, a course in assembler language programming is often the first, and sometimes the only, introduction a student has to a machine's hardware. For this reason alone, assembler language programming courses should not be removed from a curriculum; instead, they should be kept and taught in conjunction with modern software engineering practices. This article describes an alternative approach to teaching assembler language programming. Whereas the students are still introduced to a machine and its assembler language, they are required to write several low‐level library routines they used in introductory courses (such as ACM CS1 and CS2). Furthermore, the S‐Machine's support software allows students to study the internals of an assembler, a librarian, and a linker.     

Complex Systems Approaches to Educational Research: Introduction to the Special Issue

Abstract

To explore the movement toward increased complex systems (CS) research in education, this special issue of the Journal of Experimental Education was developed to identify some under-examined places where CS approaches have advanced research. The articles provide empirical examples of research leveraging methods and analyses from complexity science. In this introduction article to the special issue, we discuss the authors’ contributions to defining and explicating concepts and methods that fall under the umbrella of CS perspectives and how these methods were used to investigate complex processes in their topics of study. The articles capture the goal of the special issue to demonstrate how the research questions framed by CS assumptions can change our expectations about the very nature of the processes under study in education. We then take a more global perspective and acknowledge the commonalities amongst the papers, including (a) the reliance on intensive data to answer research questions, and (b) the use of dynamic approaches that yield findings about the stability and change of these systems and phenomena.     

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.     

Tensions in learning content and technology: the experience of education students in a web-based research project

Abstract

There has been little research on how a content-based teacher education course can embed effective training in the use of the World Wide Web to search for information and present learning outcomes. To address this gap, the present study documents the experience of 64 pre-service and inservice teachers who completed a web-based group project in an applied linguistics course. Participants expressed general appreciation of the experience but also felt tension between technology and content learning. The study raises questions about the role of technology in knowledge construction, teachers' beliefs regarding what constitutes learning in a content-based course, and how new technology can be used to enhance the learning of content knowledge.     

A longitudinal study on boys’ and girls’ career aspirations and interest in technology

Background: More young people, boys and girls, are needed in technical studies and professions, as the relative number of students in technology-related studies has been decreasing in most industrialised countries. To overcome this decrease several countries implemented mandatory technology classes in the curriculum of secondary education.

Purpose: This study has two goals: exploring the evolution of pupils’ interest during the year(s) they attend the mandatory technology classes and exploring determining characteristics for differences in boys’ and girls’ attitude change over time.

Sample: This study focuses on data gathered in the first and second grade of the first cycle in general secondary education in the North region of Belgium, Flanders. In a first stage we selected a good representation of geographically spread schools (n = 20), from which over 1300 students participated.

Design and methods: A longitudinal study with eight measurement occasions spread over the course of two years is presented in order to capture the evolution of students’ attitudes, making use of a multilevel growth model analysis.

Results: The results show that students’ interest in technology decreases over time, although at the end of each grade interest is increasing again. Boys’ and girls’ interest in technology also evolves a little different in the first cycle of secondary education. For career aspirations we didn’t see any significant difference between boys and girls. Boys’ and girls’ aspirations decrease over time with a little increase by the end of the second grade. Students with a more technological curriculum also have more career aspirations in the field of technology than their peers with other curricula. Although students’ perceptions about technology as a subject for boys and girls are largely stable.

Conclusions: The evolution of students’ attitude is far from linear, this strengthens us in the choice for a more complex analysis model and the choice for more measuring points than only at the beginning and the end when analysing students’ attitudes towards technology. With this research we found that students interest and aspirations in the field of technology are not stable and do change in the first cycle of secondary education. Overall, we can conclude that if the goal of technology education at school maintains to promote ‘a larger number of students in technological oriented studies and professions’, there is still much to do.     

CS1: how will they do? How can we help? A decade of research and practice

ABSTRACT

Background and Context: Computer Science attrition rates (in the western world) are very concerning, with a large number of students failing to progress each year. It is well acknowledged that a significant factor of this attrition, is the students’ difficulty to master the introductory programming module, often referred to as CS1.

Objective: The objective of this article is to describe the evolution of a prediction model named PreSS (Predict Student Success) over a 13-year period (2005–2018).

Method: This article ties together, the PreSS prediction model; pilot studies; a longitudinal, multi-institutional re-validation and replication study; improvements to the model since its inception; and interventions to reduce attrition rates.

Findings: The outcome of this body of work is an end-to-end real-time web-based tool (PreSS#), which can predict student success early in an introductory programming module (CS1), with an accuracy of 71%. This tool is enhanced with interventions that were developed in conjunction with PreSS#, which improved student performance in CS1.

Implications: This work contributes significantly to the computer science education (CSEd) community and the ITiCSE 2015 working group’s call (in particular the second grand challenge), by re-validating and developing further the original PreSS model, 13 years after it was developed, on a modern, disparate, multi-institutional data set.     

THE COLLABORATIVE COURSE: INNOVATIVE TEACHING AND LEARNING

Advances in information technology provide an opportunity for academic librarians and professors to offer innovative collaborative courses. The purpose of collaboration between a faculty member and a professional librarian is to integrate instruction in the course subject matter with bibliographic instruction. This integration promotes learning information acquisition skills and critical thinking, as well as the use of library resources. Research skills that students need in order to use contemporary information technology are included. The integration of those skills with the subject material of the course is described.

Two applications of freshman/sophomore level courses are discussed in the paper. Course rationale, topics, and course assignments are illustrated. It is argued that students must learn modern methods of acquiring information in order to make informed independent judgments and in order to achieve understanding in any particular discipline. Providing students with the skills required to achieve access to the ever‐widening body of available information is an essential requirement of contemporary liberal education. These skills are transferable to subsequent course work and will provide the basis for life‐long learning habits. The paper presents the argument that students' achievement of “library literacy” can be promoted by effective course collaboration between faculty members and professional librarians. Benefits and problems of such collaborative courses are also discussed.     

Pre-service teachers' views on their information technology education

Abstract

The concern that teachers are being inadequately prepared by their pre-service education to be confident and competent users of information technology remains, despite over a decade of computer availability in education systems. This paper examines the views of 234 pre-service teachers who experienced an information technology component in their teacher education course. It finds that many students have low computer self-efficacy and express negative feelings about information technology. These perceptions are gender and age related. It concludes that the need for information technology competency training remains important, but such programmes need to be specifically tailored to account for the wide range of experiences and attitudes of pre-service teachers.     

High-School Students' Attitudes Regarding Procedural Abstraction

During the last decade a new computer science curriculum has been taught in Israeli high schools. This curriculum introduces CS concepts and problem-solving methods independently of specific computers and programming languages, along with the practical implementation of those concepts and methods encountered in actual programming languages. The advanced study unit of the curriculum, Software Design, introduces the students to various aspects of software systems design through the use of abstract data types (ADTs). One main goal of the unit is to develop abstract thinking skills and problem-solving abilities. More specifically, the unit presents principles such as procedural abstraction, data abstraction, information hiding, modularity, efficiency, and reuse of code.We present the results of a preliminary study whose aim was to assess students' attitudes regarding procedural abstraction. The research population consisted of high-school students who attended the Software Design course (beginners), and a control group of undergraduate CS students (advanced). The results of the study clearly indicated a significant difference between the attitudes of the two groups. We found that the advanced students preferred algorithms that were formulated to some extent with high-level abstraction; however, they encountered a cognitive barrier when dealing with algorithms that they had evaluated as too abstract for them. However, beginners felt more comfortable with algorithms with low-level abstraction. Nevertheless they showed open-mindedness toward some degree of procedural abstraction. The results of the study were used to design scaffolding problem-solving tools for algorithm development, utilizing procedural abstraction techniques that can be adapted to various student populations (Haberman, B. (2002) SIGCSE Bulletin, 34(4), 60–64).     

Beyond the GRE: Using a Composite Score to Predict ?the Success of Puerto Rican Students in a Biomedical ?PhD Program

The use and validity of the Graduate Record Examination General Test (GRE) to predict the success of graduate school applicants is heavily debated, especially for its possible impact on the selection of underrepresented minorities into science, technology, engineering, and math fields. To better identify candidates who would succeed in our program with less reliance on the GRE and grade point average (GPA), we developed and tested a composite score (CS) that incorporates additional measurable predictors of success to evaluate incoming applicants. Uniform numerical values were assigned to GPA, GRE, research experience, advanced course work or degrees, presentations, and publications. We compared the CS of our students with their achievement of program goals and graduate school outcomes. The average CS was significantly higher in those students completing the graduate program versus dropouts (p < 0.002) and correlated with success in competing for fellowships and a shorter time to thesis defense. In contrast, these outcomes were not predicted by GPA, science GPA, or GRE. Recent implementation of an impromptu writing assessment during the interview suggests the CS can be improved further. We conclude that the CS provides a broader quantitative measure that better predicts success of students in our program and allows improved evaluation and selection of the most promising candidates.     

Inverting the Transition-to-Proof Classroom

Abstract

In this paper, we examine the benefits of employing an inverted or “flipped” class design in a Transition-to-Proof course for second-year mathematics majors. The issues concomitant with such courses, particularly student acquisition of “sociomathematical norms” and self-regulated learning strategies, are discussed along with ways that the inverted classroom can address these issues. Finally, results from the redesign of a Transition-to-Poof class at the author’s university are given and discussed.     

Project Infusion: teachers,training, and technology

ABSTRACT

This paper describes a teacher training project at Barry University in Miami Shores, Florida. The purpose of this project is to develop, implement, and evaluate a model for providing district‐wide teacher training in the use and integration of instructional technology to achieve curricular goals that are competency‐based and designed to be world class standards. The project was funded by the US Department of Education's Fund for Innovation in Education for a period of three years. During that time, 284 elementary teachers received graduate credit at Barry University for participation in an intensive course on the infusion of technology across the curriculum and for conducting teacher training at their own schools. This paper describes the teacher training model and preliminary results of the project.     

Accessing ICLAS Network Log Data to Study Student Computer Usage,Course Performance,and Attitude Change

ABSTRACT

This study demonstrated how network usage logs such as those generated by the IBM Classroom Local Area Network Administration System (ICLAS) can be used to study student use of software available on a local area network. Software instrumentation was developed to convert ICLAS log files to a format (?.DIF) usable by spreadsheet and statistics software. Data on 163 students enrolled in an ‘Introduction to Computers in Education’ course during the Summer, 1992 session at the University of South Florida were compiled for exploratory analysis. Correlations of lab use time to course grade, change in knowledge, and change in attitude were performed. It was found that amount of lab use correlated significantly to general attitude toward computers, but that it did not correlate significantly to change in attitude toward school uses of computers or to change in knowledge of course topics.
