Case‐Based Teaching: Four Experiences in Educational Software Design

Abstract

Good teaching is good story telling. Case‐based teaching exploits the basic capacity for students to learn from stories and the basic desire of teachers to tell stories that are indicative of their experiences. The premise of software that used case‐based teaching would be to place a student in a situation that the student found interesting and where the telling of a story would be appreciated. First, case‐based teachers teach the student what he or she needs to know at precisely the point of becoming interested in knowing the information. This information should be presented in the form of stories. Law schools and business schools have been teaching this way for years. They teach cases rather than rules because, by and large, they don't have rules to teach. The second critical part of learning in a case‐based environment is teaching a student to abstract from what the student has been told, and adapting it to situations for which the student was not specifically trained.

At the Institute, we have, to date, built four examples of case‐based teaching software. The programs are:

VICTOR — a voice and image courtesy tutor — built for Ameritech

DUSTIN — a language experience — built for Andersen Consulting

CREANIMATE — a biology experience‐built for schools and supported by IBM

TAXOPS — a tax opportunity advisor and cross seller — built for the Tax division of Arthur Andersen     

An example based environment for beginning programmers

Making a good programming environment for beginning programmers is an enterprise which can exploit the strong connections between machine learning and human learning. Applying what we know about teaching and learning to improve the programming environment can result in a system which allows beginners to more readily acquire programming skills.Surprisingly, a universally accepted principle of good teaching and good learning has not been taken seriously enough in designing programming environments-learning by example. A good teacher presents examples of how to solve problems, and points out what is important about the examples. The student generalizes from the examples to learn principles and techniques. This paper describes a programming environment called Tinker, in which a beginning programmer presents examples to the machine, distinguishing accidental and essential aspects of the examples. The programmer demonstrates how to handle the specific examples, and the machine formulates a procedure for handling the general case. Because people are much better at thinking about concrete examples than they are at thinking about abstractions, and because examples provide immediate feedback, Tinker is a more congenial environment for a beginner than conventional programming systems.     

Project R.A.C.E.

Abstract

Learning by doing may not be the most effective strategy for teaching environmental problem-solving skills. A survey of Michigan educators indicates that of the teaching strategies listed, case studies and talking about what others do to solve environmental problems are the most important. The implications of building familiarity with environmental issues and solutions from a variety of examples are discussed, and an explanation for the reported low success of classroom action projects is presented.     

Revisiting Peirce’s account of scientific creativity to inform classroom practice

Abstract

Peirce made repeated attempts to clarify what he understood as abduction or creative reasoning in scientific discoveries. In this article, we draw on past and recent scholarship on Peirce’s later accounts of abduction to put a case for how teachers can apply his ideas productively to elicit and guide student creative reasoning in the science classroom. We focus on (a) his rationale for abduction, (b) conditions he recognised as necessary to support this speculative reasoning, (c) pragmatic strategies to guide inquiry and test conjectural hypotheses, and (d) his growing recognition of creative dimensions to reasoning beyond abductive inference-making. We illustrate this case through examples of a guided inquiry approach to student claim-making in the science classroom.     

Teacher Testing and the Improvement of Practice

Previous approaches to teacher testing have been criticized for poorly representing the knowledge base for teaching, for oversimplifying teaching decisions, and for lacking criterion-related validity evidence supporting their use. A new generation of teacher assessments has been developed in the United States through the efforts of the National Board for Professional Teaching Standards and a corollary organization of more than 30 states. These performance-based assessments use videotapes of teachers' practice, examples of lessons and assessments, samples of student work, and analyses of classroom events and outcomes to provide evidence about teaching. Early research on the effects of these assessments suggests that they may be more valid measures of teacher knowledge and skill and that they may help teachers improve their practice. The stimulus to teacher learning appears to occur through task structures that require teachers to learn new content and teaching strategies as part of their demonstration of performance and through the processes of required reflection about the relationships between learning and teaching.     

Reflective Classroom Practice: case studies of student teachers at work

Abstract

This paper addresses the nature of reflective classroom practice in a setting where action research has been undertaken by both the student teachers and the teaching practice supervisor. It is based on a cross‐case study of the processes through which student teachers learn to teach. Specifically, the analysis focuses on how student teachers reflect on their experiences in learning to teach. The data are based on student teachers’ reported thoughts about their learning over a period of one year. The results contribute to the understanding of reflective classroom practice by highlighting first student teachers’ perceptions about learning to teach and second their reviews on classroom practice. The discussion also adds to the literature on teacher development taken from the novice‐expert research tradition. Accordingly, implications for curriculum development in teacher education are drawn.     

The Antiracism Field Assignment

Abstract

As a second article in a series devoted to an ongoing evaluation of our antiracism field project, a controversial assignment rooted in our Smith College School for Social Work's antiracism commitment, this paper focuses on the review of 128 assignments completed between September 1998-August 2000. A thematic analysis of these projects revealed interesting findings regarding the types of projects, population served, race of student, institutional receptivity, factors that enhanced or impeded student learning, obstacles encountered and degree of collaboration. Specific case examples are included that illuminate the complexity of the processes involved in learning skills utilized in antiracism work.     

Measuring Attitudinal Outcomes of Child Psychology with The Parental Attitude Research Instrument

Abstract

The assumption that laboratory training in specific teaching skills is directly related to classroom performance was tested for a sample of 32 elementary student teachers. Eight to 20 weeks after laboratory training of experimental groups and testing to verify initial training effect" samples of teaching performance of all Ss were recorded in the student teaching classrooms. These recordings were coded for exhibition of target skills by application of a low-inference category instrument which yielded scores representing rates of occurrence of the target skills per minute of teacher talk. Using a two-way analysis of variance, a statistical comparison of the rates of exhibition of the target skills by the experimental and control groups revealed no significant differences. These results are discussed in terms of the possible causes of such a lack of significant relationships between groups.     

Can ‘pooling teaching tips’ be more than ‘pooling teaching tips’?

Abstract

There is increasing interest in how academic development of various kinds influences university teaching and student learning. To date the focus has been on formal, expert-led opportunities to learn how to teach. Our institution has developed a less formal, participant-led forum for teaching staff that was initially established to share ideas on teaching techniques and skills. We report here on participant-led research that explores if and how this model of group learning works, and how it might relate to other models that have been applied to tertiary teaching development. Authors adopted a self-study research framework incorporating a collaborative autoethnography. The data emphasises how participants use this forum as a community of practice, as a means for deep engagement with learning about teaching, and as a means to rationally manage their learning against a backdrop of challenges associated with learning to teach in research-led higher education.     

Collaborative learning and teaching: Reflections on a facilitated journey

Abstract

This report summarises the first year of an innovative and multilayered teaching and learning collaborative experience within the context of an undergraduate unit in early childhood. The facilitative influence is two‐fold: (a) generic information skills training (GIST) project which is a joint initiative between the Institute of Early Childhood (IEC), the Library and the Centre for Flexible Learning to teach information literacy skills which are contextualised within the unit presentation mode, its requirements and assessment tasks, and (b) redesign of the unit from a former third‐year level to a first‐year level to incorporate the notion of problem‐based, collaborative teaching and learning. Many challenges were faced by those involved in the unit in its first year, mainly class size and heterogeneity of student levels, incorporation of technology into learning and teaching, and flow of information for smooth operations for students, the teaching team and Library staff. Multilevel collaborations were central to this experience, and examples of student‐student, student‐teacher, and teacher‐staff collaborations are provided. The first of the 2‐year cycle of the GIST project has generated substantive data, as has the implementation of the unit in an innovative format. The complexity and challenges presented in the unit seemed to account for student withdrawal of about 25% in the first month; final evaluations are obtained from 292 students. Survey results presented here are both from the withdrawn students, as well as those who completed the unit. Modifications to the delivery of the unit in its second year and ways of strengthening the communities of learners and teachers towards a common goal are briefly reviewed.     

The Challenge to Challenge: Shifting the Motivational Climate of the College Classroom for Enhanced Learning

Abstract

Student motivation for achievement is a particular concern in college teaching. The desire for students to learn for the sake of learning is strong, yet this often leads to “dumbing down” the curriculum. In this article, I present a case analysis of motivational dimensions of instructional practice in college classrooms using a social cognitive theory approach. Three dimensions are discussed: task, authority, and evaluation. Examples are provided to describe the role that challenge and support play in each of these dimensions. Implications for student motivation and learning are provided.     

Which Technique is most Effective for Learning Declarative Concepts—Provided Examples,Generated Examples,or Both?

Students in many courses are commonly expected to learn declarative concepts, which are abstract concepts denoted by key terms with short definitions that can be applied to a variety of scenarios as reported by Rawson et al. (Educational Psychology Review 27:483–504, 2015). Given that declarative concepts are common and foundational in many courses, an important question arises: What are the most effective techniques for learning declarative concepts? The current research competitively evaluated the effectiveness of various example-based learning techniques for learning declarative concepts, with respect to both long-term learning and efficiency during study. In experiment 1, students at a large, Midwestern university were asked to learn 10 declarative concepts in social psychology by studying provided examples (instances of concepts that are provided to students illustrate how the concept can be applied), generating examples (instances of concepts that the student generates on his or her own to practice applying the concept), or by receiving a combination of alternating provided examples and generated examples. Two days later, students completed final tests (an example classification test and a definition cued recall test). Experiment 2 replicated and extended findings from experiment 1. The extension group was a variation of the combination group, in which participants were simultaneously presented with a provided example while generating an example. In both experiments, long-term learning and study efficiency were greater following the study of provided examples relative to the other example-based learning techniques.     

Enhancing the Student Experience for Direct Entrants to the Penultimate Year of Undergraduate Degree Programmes

In higher education, modifications to student induction would be broadly beneficial in order to take account of the changing student population and its increasingly diverse needs. A case study of one rather innovative approach to induction is described where a pre-semester credit-bearing bridging module is mounted. This module is designed for Higher National Diplomates from the Further Education sector who have gained direct entry to the penultimate year of a university degree course. The module has five broad aims: to facilitate general integration into the university; to familiarise students with the main methods of teaching, learning and assessment that they will experience; to develop the skills necessary for successful independent study in higher education; to build self-confidence; and to improve the appropriate skills which will enhance career prospects.     

Infusing Content About Discharging Legal Responsibilities into Social Work Practice Classes

ABSTRACT

In social work education, legal content may be best conveyed through infusion, rather than specialized law/social work courses. Infusion will occur differently in each social work education sequence (practice, human behavior, policy, and research). When infusing content about discharge of legal responsibilities into a practice class, the instructor should choose a common legal topic, and teach the relevant knowledge and skills. As the instructor generalizes from the topic presented, students learn that most legal topics affect practice in a complex manner. The example of legally mandated child maltreatment reporting is used to demonstrate knowledge, skills, and teaching methods. Implications are presented for social work literature, and for contact between social work faculty and field instructors.     

A case study of scientific reasoning

Concern is increasingly being expressed about the teaching of higher order thinking skills in schools and the levels of understanding of scientific concepts by students. Metaphors for the improvement of science education have included science as exploration and science as process skills for experimentation. As a result of a series of studies on how children relate evidence to their theories or beliefs, Kuhn (1993a) has suggested that changing the metaphor to science as argument may be a fruitful way to increase the development of higher order thinking skills and understanding in science instruction. This report is of a case study into the coordination of evidence and theories by a grade 7 primary school student. This student was not able to coordinate these elements in a way that would enable her to rationally consider evidence in relation to her theories. It appeared that the thinking skills associated with science as argument were similar for her in different domains of knowledge and context. Specializations: science learning, scientific reasoning, learning environments, science teacher education. Specializations: cognition, reasoning in science and mathermatics.     

Toward Expert Thinking: How curriculum case writing prompts the development of theory-based professional knowledge in student teachers

The present paper explores what, and how, student teachers may learn about theory and practice from writing cases, and examines some pedagogical features that may contribute to these results. Drawing on data collected from our course "Principles of Learning for Teaching", including student cases from outline to final drafts and students' course reflections, we found that students' successive case drafts demonstrated a development from naïve generalizations to sophisticated, theory-based explanations of the issues at play in their cases. In particular, we suggest that students' cases demonstrated some of the moves that Berliner (1986, 1991) identified as characteristic of more "expert" thinking about teaching. We propose that reading theory in context with writing cases, that sharing cases with peer readers, that specific, theoretically grounded, and concrete feedback from instructors, and that providing multiple opportunities for revision may have been most useful in helping student teachers learn to think like a teacher.     

The Relationship between Personality and Achievement Variables in the Elementary School

Abstract

A 20-hour training program in human relations skills was provided for two groups of student teachers using the model initially developed by Carkhuff (3). One group received training concurrent with the student teaching experience while the other received human relations training immediately prior to student teaching experience. A control group of student teachers received no training. Results indicated that the training was highly successful, however, the group trained before the student teaching experience decreased in human relationship skills following the experience. The concurrently trained group, while exhibiting no deterioration, did not achieve as high an initial level of functioning as the former group. The attitudes of both experimental groups toward the training experience were extremely favorable. Implications of the findings for the timing of human relations training groups in the teacher education process were considered.     

Assessing computer technology in the criminal justice classroom: A case study

Previous research examining computer-assisted teaching is inconclusive. Some studies find enhanced student performance while others find no difference from traditional-approach pedagogy. This case study compares student performance and course evaluations for computer-assisted and traditional-approach sections in three criminal justice courses: crime theory, criminal courts, and inequality in the justice system. Overall results indicate a significant difference between student performance in computer-assisted and traditional classes. Yet differences are not the same for each course. The theory course shows the least difference while the courts course had the greatest difference. Student evaluation data indicate computer-assisted activities are enjoyed, yet differences from traditional-approach sections are not significant. Questions for future research on the use of technology in teaching are raised.     

Benefits of self‐paced learning modules for teaching quantitative methods in environmental science

Abstract

This is a multiple‐indicators evaluation of an innovative approach, using self‐paced learning modules accompanying computerised exercises as an adjunct to teaching quantitative concepts and skills to environmental science students at university. The evaluation data, based on a pre‐unit and a post‐unit questionnaire survey completed by 38 students, show high levels of student satisfaction with the unit as a whole, and the self‐paced workbooks in particular. Students also indicated a clear preference for learning from self‐paced workbooks compared to learning from textbooks. Some students applied the quantitative skills acquired to other academic units, or took the initiative to learn to use additional statistical procedures (not covered in the unit) for academic purposes. However, comparison of students’ levels of interest and confidence in quantitative subjects before and after the completion of the unit did not yield significant changes. Implications of the research findings for university science education are discussed.
