We revisit the relationship between attendance and performance in the undergraduate university setting and apply agency theory in the instructor–student context. Building on agency theory propositions in the educational setting advanced by Smith, Zsidisin, and Adams (2005) , we propose that the student and instructor must align goals to promote the student's achievement of performance learning outcomes, and attendance functions as a behavior‐based alignment mechanism to encourage the convergence of faculty and student interests. Further, we propose that attendance does not equally affect lower‐ and higher‐performing students and that absences are also negatively related to students' cumulative grade point average. We test these hypotheses with data from undergraduates enrolled in management courses at a state university in the southeast. Our results show that attendance is positively related to exam performance, there are more pronounced negative effects of an absence for lower‐performing students than for higher performers, and absences are negatively related to a student's cumulative grade point average. We discuss the implications of our findings for students, instructors, and universities as well as practice in teaching and learning. 相似文献

Pigeons pecked on three keys, responses to one of which could be reinforced after 3 flashes of the houselight, to a second
key after 6, and to a third key after 12. The flashes were arranged according to variable-interval schedules. Response allocation
among the keys was a function of the number of flashes. When flashes were omitted, transitions occurred very late. Increasing
flash duration produced a leftward shift in the transitions along a number axis. Increasing reinforcement probability produced
a leftward shift, and decreasing reinforcement probability produced a rightward shift. Intermixing different flash rates within
sessions separated allocations: Faster flash rates shifted the functions sooner in real time, but later in terms of flash
count, and conversely for slower flash rates. A model of control by fading memories of number and time was proposed. 相似文献

This study examined learning in the domain of sentence parsing and syntax treediagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations. 相似文献

Designing Instructional Examples to Reduce Intrinsic Cognitive Load: Molar versus Modular Presentation of Solution Procedures 总被引:2,自引:1,他引:2
It is usually assumed that successful problemsolving in knowledge-rich domains depends onthe availability of abstract problem-typeschemas whose acquisition can be supported bypresenting students with worked examples.Conventionally designed worked examples oftenfocus on information that is related to themain components of problem-type schemas, namelyon information related to problem-categorymembership, structural task features, andcategory-specific solution procedures. However,studying these examples might be cognitivelydemanding because it requires learners tosimultaneously hold active a substantial amountof information in working memory. In ourresearch, we try to reduce intrinsic cognitiveload in example-based learning by shifting thelevel of presenting and explaining solutionprocedures from a `molar' view – that focuseson problem categories and their associatedoverall solution procedures – to a more`modular' view where complex solutions arebroken down into smaller meaningful solutionelements that can be conveyed separately. Wereview findings from five of our own studiesthat yield evidence for the fact thatprocessing modular examples is associated witha lower degree of intrinsic cognitive load andthus, improves learning. 相似文献

Teachers, unlike their counterparts in other professions such as doctors and lawyers, lack professional control over their profession. This paper examines how this has come about in the United Kingdom by identifying the problems in seeing teaching as a profession and explains why the professional development of teachers should be a central concern of universities. Many parallels can be drawn with problems highlighted in this paper and those encountered elsewhere. 相似文献

This introduction to the special issue on Genes, Environment, and Reading presents an overview of the background for behavior-
and molecular-genetic research on dyslexia and individual differences across the normal range. The general methods, questions
addressed, and selected results are summarized for each of the papers in the order of their presentation in the special issue.
Concluding comments reflect on the influence of environmental range on estimates of genetic and environmental influences,
and the future of behavior- and molecular-genetic research on reading. 相似文献

In this paper, a method for analyzing data from student evaluations of teaching is presented. The first step of the process requires development of a regression model for teacher's summary rating as a function of student's expected grade. Then, two‐sigma control charts for individual evaluation scores (section averages) and residuals from the regression model are used to identify both excellent and poor outcomes. The performance of an individual whose scores are out of control on both charts cannot be explained by expected grade and therefore is worthy of note. 相似文献

Peer evaluation: A case study 总被引:1,自引:0,他引:1
Peer evaluation is the process whereby students critique the performances of other students. A peer evaluation format emphasizes skills, encourages involvement, focuses on learning, establishes a reference, promotes excellence, provides increased feedback, fosters attendance, and teaches responsibility. The process of peer evaluation is explained, the criteria are specified, the training for use is described, and how standards are maintained is explained. Finally, objections are suggested and addressed. Peer evaluation is a unique, controlled, and precise form of classroom evaluation that involves carefully constructed evaluation instruments, structured classroom situations, and exact evaluative assessments. Peer evaluation is a new and different form of evaluation. 相似文献

ABSTRACTA large diversity of theoretical frameworks exists in the physical education literature. This article focuses on two of those frameworks to examine their compatibility and their complementarity. The classroom ecology paradigm concentrates on the balance between three task systems, two vectors, and programs of actions proposed by the physical education teacher and negotiated by students. The didactique research program studies the teaching and learning processes using the concepts of didactic contract and didactic milieu that focus on how the knowledge content emerges within teacher and students’ joint action. The article underlines the complementarity and the compatibility of the two frameworks when analyzing teaching and learning in physical education. It argues that the gray areas left by the classroom ecology paradigm could be filled with the insights of the didactique research program. A concise example of how the two frameworks have already been utilized is presented. 相似文献
