Using MEL in a networked classroom

With Micro Experimental Laboratory (MEL) and network software in a computer-assisted classroom, an instructor can run class demonstrations and projects with great control and flexibility. The network allows quick file transfer between the instructor’s and the students’ machines. MEL allows easy reprogramming of experiments for more interactive demonstrations, and data merging for comparison of individual and group data. In this article, the pros and cons of running MEL on a network are discussed, and its use at the University of California at Berkeley is outlined.     

Student MEL software support for instructors and teaching assistants in research methods course

A number of common problems plague the teaching of the undergraduate research methods course, from the training of teaching assistants to providing meaningful experimental materials to handling data acquisition and analysis. The Student Micro Experimental Laboratory (MEL) offers a systematic approach to the management of a computerized research methods laboratory course by combining high-quality experiments in many areas of psychology with background materials to help the instructor and teaching assistant. The software presents and collects data from 28 experiments. The data can be analyzed for single subjects and for classes as a whole. Students can rapidly implement new experiments in a variety of paradigms. An expanding library of experiments created by students and instructors should provide an expanding environment for teaching experimental research methods. Instructor’s materials provide background information, discussion questions, and data analysis for all experiments. The student workbook provides discussion of the background of the experiment, details of the methodology, and questions addressing various aspects of experimental design and interpretation of data.     

Micro Experimental Laboratory: An integrated system for IBM PC compatibles

Micro Experimental Laboratory (MEL) is a third-generation integrated software system for experimental research. The researcher fills in forms, and MEL writes the experimental program, runs the experiments, and analyzes the data. MEL includes a form-based user interface, automatic programming, computer tutorials, a compiler, a real-time data acquisition system, database management, statistical analysis, and subject scheduling. It can perform most reaction time, questionnaire, and text comprehension experiments with little or no programming. It includes a Pascal-like programming language and can call routines written in standard languages. MEL operates on IBM PC compatible computers and supports most display controllers. MEL maintains millisecond timing with high-speed text and graphics presentation. MEL provides a systematic approach to dealing with nine concerns in running an experimental laboratory.     

Using internet resources in a research methods course

Internet resources (a WWW home page, a Unix-based Listserv discussion list, and e-mail) were used to supplement traditional materials in a research methods course. The course also included word processing and computerized data analysis, and the student version of MEL was used as a research simulator. A computer usage survey was administered at the beginning and end of the semester. Analysis of the survey results indicated that students were more positive in their attitudes about computers as a helpful tool for psychologists at the end of the course than at the beginning. They did not show an increased appreciation for the usefulness of Internet and e-mail, however, which is probably the result of the text-based Internet browser and the slowness of the e-mail system used.

This report presents a simple way to implement and use an expanded MEL response box that accommodates up to 16 external switches. Hardware and software considerations are reviewed, and relevant MEL code is provided. This includes a simple algorithm that permits the reading of multiple responses within a single trial.     

A psychotherapeutic computer application: Modification of technological competence

The increasing sophistication of computer technology, combined with increased specification of therapeutic interventions, has facilitated development of computer programs that have achieved marked success in the psychotherapeutic treatment of circumscribed populations. This paper briefly reviews the history of computerized psychotherapy and examines several successful therapeutic computer applications in depth. These applications have attempted to replace the therapist with a computer. Another possible, as yet unexplored, application is the use of the computer as a vehicle for modification of an individual’s perceived competence to effectively operate on his or her environment. Using a computer to successfully manipulate one’s environment can provide a personal mastery experience that has the potential to contribute significantly to an increase in perceived self-competence, an essential component of positive therapeutic change. A study that would provide empirical support for this type of computer application is proposed.     

Microprocessors: Their impact on real-time computing in psychology

This paper attempts to evaluate the impact of microprocessors and other products using large-scale integrated circuit technologies with a set of examples of past, current, and proposed computer applications in psychological research. I first discuss a number of developments in real-time computing that have taken place during the last 10 years. The major part of this paper describes future developments in the Computer Laboratory for Instruction in Psychological Research. We are developing an intelligent high-speed communication network that will enable computers and terminals to communicate with each other. In addition, we are developing a microprocessor-based real-time computer system. The network, the real-time system, and the general assumption underlying the development of the next generation of CLIPR facilities are described.     

Use of a common software system for collaborative clinical research on attentional processes in schizophrenia and ADHD

MacArthur Network III, consisting of five nodes (locations) and over 100 investigators, was formed in 1983 to conduct collaborative clinical research on risk and protective factors associated with psychiatric disorders. The common measurement of attentional dysfunction associated with two specific disorders (schizophrenia and attention deficit-hyperactivity disorder) was a goal of a subgroup of 11 Network III investigators. In this paper, the experiences with five approaches for implementing common protocols on laboratory computers for collaborative clinical research are described. The reasons for selecting the approach provided by Schneider’s (1988) MEL system are presented and discussed.     

Digital LED Pixels: Instructions for use and a characterization of their properties

This article details how to control light emitting diodes (LEDs) using an ordinary desktop computer. By combining digitally addressable LEDs with an off-the-shelf microcontroller (Arduino), multiple LEDs can be controlled independently and with a high degree of temporal, chromatic, and luminance precision. The proposed solution is safe (can be powered by a 5-V battery), tested (has been used in published research), inexpensive (～ $60 + $2 per LED), highly interoperable (can be controlled by any type of computer/operating system via a USB or Bluetooth connection), requires no prior knowledge of electrical engineering (components simply require plugging together), and uses widely available components for which established help forums already exist. Matlab code is provided, including a ‘minimal working example’ of use suitable for use by beginners. Properties of the recommended LEDs are also characterized, including their response time, luminance profile, and color gamut. Based on these, it is shown that the LEDs are highly stable in terms of both luminance and chromaticity, and do not suffer from issues of warm-up, chromatic shift, and slow response times associated with traditional CRT and LCD monitor technology.     

From the Laboratory to the Classroom: The Effects of Equivalence-Based Instruction on Neuroanatomy Competencies

Equivalence-based instruction (EBI) has been used to successfully teach college-level concepts in research laboratories, but few studies have examined the results of such instruction on classroom performance. The current study answered a basic question about the ordering of training stimuli as well as an applied question regarding the effects of EBI on classroom performance. Students recruited from a Behavioral Neuroscience course learned neuroanatomy concepts using EBI. Outcomes revealed that the ordering of stimuli did not differentially affect performance and that students who completed the tutorial scored significantly higher on the course’s final examination than did students who had not completed the tutorial. Implications for future classroom applications are discussed.     

‘Making’ as a catalyst for reflective practice

Within the research and teaching program of maker pedagogy(TM), this study analyzes how teacher candidates construct knowledge about teaching and teaching with technology. The study applies an experiential-intuitive framework of reflective practice and takes cues from critical thinking to analyze the participants’ interactions in a maker pedagogy lab. Schön’s conception of reflection drove the data collection and analysis of participants who were asked to reflect on their experiences gained in the maker pedagogy lab. The researchers argue that the maker pedagogy lab provides participants with a way to understand their teaching practice. The results demonstrate that the maker projects enabled teacher candidates to engage in exploratory and hypothetical talk about how they are thinking about teaching and learning, particularly with technology. Furthermore, the researchers uncovered that teacher candidates’ prior knowledge and frames of reference affect their making experiences and their developing identities as science and technology teachers.     

Maximizing the mini-uses of on-line computers

This paper draws on our experiences at Carnegie-Mellon University to provide a decision framework for the acquisition of computer systems for laboratory applications. Also recommended are ways of creating an effective operating environment that can handle changing needs. Systems developed for our most recent research in eye-movement recording and children’s concept learning using the Turtle will illustrate the design principles for hardware and software components of minicomputer systems.     

Multidisciplinary Engagement with Nanoethics Through Education—The Nanobio-RAISE Advanced Courses as a Case Study and Model

This paper presents and evaluates two advanced courses organised in Oxford as part of the European project Nanobio-RAISE and suggests using their format to encourage multidisciplinary engagement between nanoscientists and nanoethicists. Several nanoethicists have recently identified the need for ‘better’ ethics of emerging technologies, arguing that ethical reflection should become part and parcel of the research and development (R&D) process itself. Such new forms of ethical deliberation, it is argued, transcend traditional disciplinary boundaries and require the active engagement and involvement of both nanoethicists and nanoscientists with the broader issues surrounding technological developments. Whereas significant research efforts into multi- and interdisciplinary collaborations during R&D processes are now emerging, opportunities for encouraging multidisciplinary engagement through education have remained relatively underexplored. This paper argues that educational programmes could be a natural extension of ongoing collaborative research efforts ‘in the lab’ and analyses how the Nanobio-RAISE courses could be used as a model for course development. In addition to exploring how the elements that were conducive to multidisciplinary engagement in this course could be preserved in future courses, this paper suggests shifting the emphasis from public communication towards ethical deliberation. Further course work could thus build capacity among both nanoscientists and nanoethicists for doing ‘better’ nanoethics.     

The Special Sign Indeterminacy of the Direct-Fitting Parafac2 Model: Some Implications, Cautions, and Recommendations for Simultaneous Component Analysis

Parafac2 is the most flexible Simultaneous Component Analysis (SCA) model that produces an essentially unique solution. In this paper, we discuss how Parafac2’s special sign indeterminacy affects applications of SCA, and we reveal how an external criterion variable can be used to ensure that estimated Parafac2 weights are meaningfully signed across the levels of the nesting mode. We present an example with real data from clinical psychology that illustrates the importance of Parafac2’s special sign indeterminacy, as well as the effectiveness of our proposed solution. We also discuss the implications of our results for general applications of SCA.     

RELEASE FROM PI: Comparison of traditional and computer modules in an experimental psychology laboratory

RELEASE FROM PI is a computer-controlled participatory module designed for use by students in laboratory sections of an experimental psychology course. It allows the student subjects to trace their recall performance across sets of four lists when the fourth list changes in physical characteristics or semantic category. The performance of students participating in this computer module was compared with that of students receiving a traditional procedure with a human experimenter. All other aspects of the laboratory session were equated as much as possible. The recall data showed that the traditional procedure produced better recall and greater release with a semantic shift. However, both methods resulted in roughly equivalent learning (as measured by multiple-choice questions) and student evaluation ratings. Implications for the use of computers in instruction and research are examined.     

Exploring Societal and Ethical Views of Nanotechnology REUs

Little previous research has examined attitudes about societal and ethical issues (SEI) among interns participating in research experience for undergraduate programs (REUs) in nanotechnology, thus neglecting an important population for understanding the burgeoning views of the next generation of nanotechnology researchers. This study surveyed a sample of interns (N?=?85) participating in the National Nanotechnology Infrastructure Network’s (NNIN) REU program during the summer of 2012. Our questions focused on interns’ experiences with education on ethical issues, as well as their attribution of responsibility for considering ethical issues, motivations to talk about ethical issues, and comfort level of discussing ethical issues with faculty, mentors, lab staff, and other REU students. Among key findings was that lab culture related to the extent to which REU interns felt comfortable discussing ethical issues. In addition, those who reported more discussions about ethical issues with their mentors were more likely to consider themselves as responsible for considering ethical issues. We conclude with recommendations and future research directions.     

The Low Risk Research Ethics Application Process at CQUniversity Australia

The CQUniversity Australia Human Research Ethics Committee (HREC) is a human ethics research committee registered under the auspices of the National Health and Medical Research Council. In 2009 an external review of CQUniversity Australia’s HREC policies and procedures recommended that a low risk research process be available to the institution’s researchers. Subsequently, in 2010 the Human Research Ethics Committee Low Risk Application Procedure came into operation. This paper examines the applications made under the Human Research Ethics Committee Low Risk Application Procedure during the course of 2010 and 2011. The paper contributes to the literature analyzing the decision-making processes of research review committees through an analysis of the quantitative data relating to the low risk research applications made and through discourse analysis of the qualitative data represented by the assessment comments of the members of the Committee.     

Computer interactive heuristics to assess preference indefinition and resolve discrepancies between preference ratings and rankings

Ipsative and absolute assessment of preferences are contrasted, with particular reference to the different quantitative and qualitative information provided by each. Although it may not be possible to mathematically combine the respective qualitative information provided by rankings and ratings, when used in conjunction, they may offer a valuable consistency check of a respondent’s preference assessments. A set of heuristics, interactively implemented via computer, is proposed to (1) identify inconsistencies between preference rankings and ratings of the same set of items, and (2) attempt to resolve those inconsistencies. The number of iterations required to resolve inconsistencies might be used as an index of the respondent’s lack of preference definition.     

Cutting Deep: The Transformative Power of Art in the Anatomy Lab

On Tuesday evenings at New York University School of Medicine (NYUSoM), the anatomy lab is transformed into an art studio. Medical students gather with a spirit of creative enterprise and a unique goal: to turn anatomy into art. They are participants in Art & Anatomy, an innovative drawing course within the Master Scholars Program in Humanistic Medicine (MSPHM)—a component of NYUSoM, which offers elective courses across a range of interdisciplinary topics in medical humanities. Art & Anatomy has had approximately four hundred fifty participants since its inception in 2009. The educational intention of the course is to use drawing as an active mode of learning that enhances visual-perceptual ability and three-dimensional (3D) spatial understanding of the body's interior; however, the course also opens a creative space for participants to process the emotional complexities of cadaver dissection and the anatomy lab experience. The anatomy lab can be the training ground for clinical detachment, but many U.S. medical schools are beginning to attend more closely to the emotional aspects of dissection. The authors maintain that the inherently expressive nature of drawing makes the Art & Anatomy course a novel and effective approach to this endeavor. Select student artwork and a curriculum overview are provided.     

Failure of laboratory evaluation of CAI to generalize to classroom settings: TheSuperShrink interview simulation

Laboratory settings are often used to evaluate instructional innovations. This paper reports a comparison of laboratory and course evaluation ofSuperShrink, an educational computer simulation of two comprehensive clinical interviews designed to teach undergraduates personality and diagnostic formulation. Previous experimental comparison of the computer simulation with a booklet version ofSuperShrink in a laboratory setting, carried out with volunteers from the departmental subject pool, indicated that students found the computer version more involving, enjoyable, and realistic. The present experiment involved the comparison of computer and booklet versions of two complete cases in four courses in abnormal psychology. The results opposed those from the laboratory setting. The students strongly preferred the booklet version and cited its greater convenience as one reason for their preference. Our findings suggest that care must be taken to ensure that laboratory evaluations of CAI are ecologically valid and are replicated in classroom settings.
