A simple introduction to programming and statistics with decision trees in R

University students in other disciplines without prior knowledge in statistics and/or programming language are introduced to the statistical method of decision trees in the programming language R during a 45-minute teaching and practice session. Statistics and programming skills are now frequently required within a wide variety of research fields and private industries. However, students unfamiliar with these subjects may be reluctant to join a full course because of time or student workloads or other commitments or a belief it is not for them. The proposed session is short and can be used as an ice-breaker to let students have a basic understanding of running statistical models in programming language.     

Research in online and blended learning in the business disciplines: Key findings and possible future directions

In this literature review, we examine and assess the state of research of online and blended learning in the business disciplines with the intent of assessing the state of the field and identifying opportunities for meaningful future research. We review research from business disciplines such as Accounting, Economics, Finance, Information Systems (IS), Management, Marketing, and Operations/Supply Chain Management. We found that the volume and quality of research in online and blended business education has increased dramatically during the past decade. However, the rate of progress is somewhat uneven across disciplines. IS, Management, and multi-disciplinary studies have the highest volumes of research activity, with markedly less activity in Finance and Economics. Furthermore, scholars of online and blended business education predominantly publish in learning and education journals of the business disciplines rather than also publishing in journals that focus on technology-mediated learning, thereby missing an opportunity to inform scholars in other disciplines about their work. The most common research streams across disciplines were outcome comparison studies with classroom-based learning and studies examining potential predictors of course outcomes. Results from the comparison studies suggest generally that online courses are at least comparable to classroom-based courses in achieving desired learning outcomes, while there is divergence in findings of comparisons of other course aspects. Collectively, the range of untested conceptual frameworks, the lack of discipline-specific theories, and the relative absence of a critical mass of researchers focused on the topic suggest ample opportunities for business scholars seeking to enter this research community.

Numeracy for everyone

Most techniques in statistics are used in many disciplines besides ecology and have a wide range of applications from anthropology to zoology. They are used in industry, agriculture, social sciences and business. That is why we have called this series ’Numeracy for Everyone’. In the forthcoming parts, we will discuss applications of statistics in some of these fields. But some techniques are developed specially for ecological problems. Let us briefly look at a selection of those techniques.     

Capping them off! Exploring and explaining the patterns in undergraduate capstone subjects in Australian business schools

Universities are increasingly offering capstone subjects as part of curricula to prepare final-year undergraduates for employment through consolidating and integrating their knowledge and skills while bridging the gap between academic learning and professional work. This study investigates capstone subjects offered by Australian business schools, drawing on national survey data collected in 2010 and 2011, complemented by interviews with associate deans teaching and learning instrumental in curricula design. Findings indicate the sector-wide use of capstone subjects in business disciplines, diversity in the patterns of offerings, and instances where subjects labelled as capstones do not meet the definition of capstones. We argue that these features are explained by a range of historic and strategic factors, such as the ad hoc development of subjects and a lack of understanding of the features of capstones. The findings of this paper inform the debate on the design, development, value and the use of capstone subjects identifying the implications for staff development and knowledge management in higher education.     

Learner Resistance to English-medium instruction practices: a qualitative case study

The internationalization of higher education has resulted in the growth of English-medium instruction (EMI) practices and research. The existing EMI research has documented learners’ favorable attitudes toward EMI but not necessarily its practices. Learners’ dissatisfaction has not been viewed as a form of resistance. Through the notion of learner resistance that underscores agency in defiance, this study examined the occurrences of learner resistance and the reasons for it by investigating Chinese learners’ experiences in an undergraduate business English-taught program in Taiwan. Multiple sources of data, including interviews, stories, and class observations, were gathered for analysis. The findings showed that most Chinese learners resisted an unhelpful curriculum, pedagogy, and context. Their resistance may be related not simply to academic disciplines but more importantly to a Confucian Heritage Culture of learning. Such findings highlight learner agency in resisting actions and call for further investigation into potential learner resistance in EMI practices.     

Statistical knowledge and the over-interpretation of student evaluations of teaching

Research shows that teachers interpret small differences in student evaluations of teaching as meaningful even when available statistical information indicates that the differences are not reliable. The current research explored the effect of statistical training on college teachers’ tendency to over-interpret student evaluation differences. A sample of 225 English, mathematics and psychology teachers evaluated statistical reports of student evaluation data corresponding to a fictional teacher’s courses. Teachers from the three disciplines varied significantly in their statistics training, but there were no differences in their tendency to rate small, non-significant differences in student evaluations as indicative of the need to make improvements in a course. These results illustrate that statistical knowledge alone does not prevent the over-interpretation of student evaluation means.     

Academic discipline and generalizability of student evaluations of instruction

Previous research on the generalizability of student ratings of instruction has raised questions about the effects of academic discipline and item types on the generalizability of these data for making relative decisions about instructors and about courses. In particular, although student evaluation data appear to provide a reasonable basis for making decisions about instructors when generalizing across courses and students, when course is the object of measurement, the data appear to be less generalizable. It was suggested in the literature that this may be due to the type of evaluation items used or it may be due to academic discipline differences in the type of courses selected for study. This study used Biglan's (1973a) model for classifying disciplines along the dimensions of paradigmatic/preparadigmatic (hard/soft) and pure/applied. A nested sampling procedure yielded two sample types: courses within teachers, in which individual instructors taught more than one course; and teachers within courses, in which individual courses were taught by more than one instructor. For each sample type, evaluation forms for twenty courses within each discipline classification were sought. The evaluation items for this study were classified as measuring six dimensions of instruction: organization, breadth of coverage, group interaction, enthusiasm, grading, and individual rapport. Generalizability and decision studies were conducted in which, for one sample, teacher was the object of measurement, and for the second sample, course was the object of measurement. Results indicated that reliable decisions about instructors could reasonably be made from all six of the evaluation dimensions; however, reliability for course decisions varied greatly with the evaluation dimension, being highest for breadth of coverage and lowest for grading. The same general pattern was noted for the paradigmatic disciplines and the preparadigmatic-applied disciplines but not for the preparadigmatic-pure disciplines. It is suggested that a single evaluation instrument may not be uniformly applicable to all discipline areas.

Examining Undergraduate Students’ Attitudes toward Business Statistics in the United States and China

The rapid growth of analytics is bringing more attention to quantitative core curriculum requirements in undergraduate business programs. Statistical knowledge and skills are unequivocally recognized as essential cornerstone of business analytics. Furthermore, educational research has shown that academic performance in statistics classes is related to the attitudes that students bring to the course. This article assesses the reliability and validity of the Survey of Attitudes toward Statistics (SATS) in measuring noncognitive dimensions of attitudes among undergraduate business students. Sample data from U.S. and Chinese introductory business statistics classes were collected and analyzed to learn more about this aspect of student engagement across business schools located in countries with substantially different levels of success in international mathematics achievement testing, as well as differing cultural and educational practices. Results show that the six‐factor model structure of the SATS provides a good fit in both populations, with students entering business statistics holding only slightly positive attitudes toward the subject. Significant distinctions between four of the six attitude components were identified. Implications of measuring and improving these attitudes are discussed. Business statistics instructors are encouraged to use the survey as a standardized instrument to measure effects of interventions and make evidence‐based pedagogical decisions.     

Implications of Prelecture Material on Cognitive Load and Instructional Effectiveness in Cross‐Disciplinary IS Education: The Nexus of Benford's Law and SQL

For some time, there has been a call for cross‐disciplinary teaching within the business disciplines. With the rise of data and analytics, there is an opportunity for cross‐disciplinary teaching by integrating technology throughout the business curriculum. However, many business professors have little experience in cross‐disciplinary teaching. We hope to rectify this by introducing an approach that uses prelecture material to prepare students for learning concepts and terms that are not core to the focal class. In a study that combines Structured Query Language (SQL) coding with an audit principle called Benford's Law, we analyze the impact of adding prelecture material about Benford's Law on student's cognitive load, knowledge gained, and instructional efficiency. Results indicate that students who received a prelecture on Benford's Law outperformed the control group in performance measures related to Benford's Law, and that the instructional efficiency on Benford's Law was also higher for the treatment group. We did not find any significant differences in cognitive load between the two groups, nor did the treatment group perform significantly better when tested on the SQL concepts. We conclude that cross‐discipline teaching is a fine balance between each discipline and communicating to students the importance of both disciplines is key.     

Exploring TPACK among pre-service teachers in Australia and Israel

The ubiquitous nature of technology in the world has not yet translated into the ubiquitous use of technology to transform learning and teaching. Teachers lack the confidence and competence to integrate technology across a broad range of tools within a range of contexts. Technological pedagogical content knowledge (TPACK) has become a common framework to explore technology within teaching and teacher education. However, little research exists to explore the similarities and differences of TPACK between different teacher education programmes, within different countries or even different disciplines, especially in a secondary context. Using a self-report online survey, this study sought to compare and contrast TPACK results from pre-service teachers studying in secondary teacher education programmes in Australia and Israel. Findings suggest that TPACK is higher in Australia, and in both countries for those students who were aged over 26. There were no significant differences between gender and disciplines reported. The paper also discusses broad-scale implications for the future of research in TPACK.     

On the global knowledge components in an information security curriculum–a multidisciplinary perspective

Because of the borderless feature of the Internet, information security threats could come from anywhere around the globe. In this research, we propose adding global knowledge components in the information security curriculum using a multi-disciplinary approach. We argue that a global perspective has been lacking in the current information security curriculum. We then propose several knowledge components to be added in the curriculum to enhance the global perspective. We also examine how to incorporate knowledge from various related disciplines, including political science, criminal justice, and business administration. Through our empirical study on faculty from various disciplines and the industry practitioners with first-hand information security knowledge, we confirm that the proposed knowledge components are relevant to the information security education and practice. Analyzing the similarities and differences among responses from various disciplines, we also found that albeit different disciplines have slightly different emphases on the curriculum components, they all tend to agree on the importance of adding the global perspectives in information security education. Our research could be of value to the educators in the information security field when considering incorporating a global perspective into the curriculum. It could also shed some lights when examining the relevance of global information security to various disciplines.

Gender Differences in Self‐efficacy and Academic Performance among Students of Business Administration

Gender differences in perceived self‐efficacy and academic performance in marketing, organizational behaviour, accounting, computing, mathematics and statistics were investigated in 154 college students studying business administration. At the beginning of their second year in college, the students completed a questionnaire designed to measure self‐efficacy in subjects they had studied during their first year. The female students had significantly lower self‐efficacy in computing and marketing and higher self‐efficacy in statistics than the male students. Except for statistics, where female students outperform their male counterparts, there were no significant gender differences in academic performance.     

An investigation of prospective secondary mathematics teachers’ conceptual knowledge of and attitudes towards statistics

The development of statistical literacy is fast becoming the focus of a large part of mathematics instruction at primary, secondary and tertiary levels. This broadening of the mathematics curriculum to encompass a focus on statistics makes considerable demands on teachers. Most mathematics teachers acknowledge the practical importance of statistics and are willing to give more relevance to the teaching of statistics; however, many mathematics teachers do not consider themselves well prepared to teach statistics. The aims of this study were to investigate the conceptual understanding of statistics of prospective secondary mathematics teachers; the nature of their attitudes towards statistics and if there was a relationship between attitude towards statistics and conceptual understanding of statistics. Conceptual understanding was measured using a standard assessment instrument (comprehensive assessment of outcomes in a first statistics course) which allows comparison across other disciplines. Despite being very mathematically able and confident, the prospective mathematics teachers in this study do no better in the assessment than students from other (mostly non-quantitative) disciplines. This, perhaps, gives further evidence that statistical thinking is different from mathematical thinking and that a strong background in mathematics does not necessarily translate to statistical thinking. Conceptual knowledge was poor in some fundamental areas of statistics such as being able to properly describe the distribution of a quantitative variable and data production. The attitudes of these teachers towards statistics were measured using a widely used instrument (survey of attitudes towards statistics). The results indicate generally positive attitudes but an acknowledgement that statistics is not a subject quickly learned by everyone and requires discipline to learn. No strong correlation was found between attitudes and conceptual knowledge. It is recommended that in order to improve teacher knowledge, teacher education programmes must include tailored modules in statistics and highlight the differences between mathematical and statistical thinking.     

Reprint requesting: A possible adjunct to citation analysis for judging research: Preliminary questions and findings

Interest in the quality of published research is evident across the range of disciplines including education. Several comprehensive studies either sponsored or published by the American Educational Research Association attest to this fact. In the sciences, citation analysis is attracting interest as a methodology for assessing research. The procedure has both theoretical and practical promise. The present study considers an overlooked source of information, reprint requesting, as a possible adjunct to citation analysis. The study stems from the questionnaire responses of 24 reprint requestors for an article by the authors. Requestor characteristics, motives, and reprint uses are considered. Implications for further research are advanced.     

Alumni Research and Criminal Justice

Alumni studies use past graduates of educational programs or institutions to address various types of research aims. While alumni research is common in disciplines such as business, psychology, nursing, and social work, few criminal justice alumni studies have been published in the academic literature. This article reviews the types of alumni studies that are typically conducted, discusses reasons for conducting criminal justice alumni surveys, considers barriers to these surveys, identifies criminal justice‐specific themes that address why alumni studies are rare in the discipline, and suggests strategies for enhancing and expanding this sort of research in the discipline.
