The empirical derivation of equations for predicting subjective textual information     

Dan Kauffman  Mike Johnson  Gene Knight 《Instructional Science》1976,5(3):253-276

Parameters pertaining to information processing by human beings have, in the past, been determined by learning and memory experiments with nonsense syllables, number sequences, etc. However, in the real world we are concerned with the processing of meaningful information, not senselles texts. Therefore, the determination of subjective information directly from meaningful material becomes extremely important in the instruction-learning process.This study derives an equation for predicting the subjective textual information contained in a text of material written in the English language. Specifically, this investigation describes, by a mathematical equation, the relationship between the subjective information content of written textual material and the relative number of errors committed by a learner when asked to predict, letter by letter, the content of given textual material. This relationship shows that the subjective information of a given text for a specific learner is directly proportional to the number of wrongly guessed signs made by that learner. This is expressed mathematically by% MathType!MTEF!2!1!+- % feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn % hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr % 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9 % vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x % fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaamysaiabg2 % da9iaaiodacaGGUaGaaGymaiaabccacaWGfbaaaa!3B57! \[ I = 3.1{\rm{ }}E \] 0935 0212 VWhere: I = Information in bits E = Number of wrongly guessed signsThe application of Shannon's guessing procedure (1951) in this study permits the measurement of the subjective information of a given text for a specific learner. Unlike senseless texts, the subjective information of a meaningful text varies from learner to learner. Therefore, the derived equation permits the measurement of information in terms of a value that is dependent not only upon the inherent qualities of the subject matter, but also upon the internal state of the learner.The derived equation for the English language is then compared to an equation derived by Weltner (1967) for the German language and found to be remarkably similar.This work was, in part, supported by United States Air Force Contract F41609-71-C-0027 entitled Flying Training Research on Airborne and Ground Training Systems, and a research grant from Arizona State University.  相似文献   

Curriculum Continuity and Transfer from Primary to Secondary School: the case of history     

Mike Huggins  Peter Knight 《Educational studies》1997,23(3):333-348

The transfer of children from primary school to secondary school has long been seen as a problematic area. The National Curriculum was depicted as offering a solution to some of the transfer problems by providing for curriculum continuity across the primary-secondary divide. This paper reports the results of a study of curriculum continuity in one subject, history, now that a National Curriculum has been in place for several years. It reports that teachers continue to see problems with the transfer and that secondary school teachers still incline to a ‘fresh start’ approach to year 7 pupils. There is also some evidence of a lack of curriculum consistency within the secondary schools involved in the research, there are differences between primary and secondary schools in the range of teaching and learning methods employed, there is some decline in pupils’ ratings of their experience of secondary education across year 7 and there are signs of some gender differences in these ratings. The conclusion is that there is a case for saying that the new arrangements have not alleviated the problems associated with the transfer.  相似文献   

#NeverAgainMSD Student Activism: Lessons for Agonist Political Education in an Age of Democratic Crisis     

Kathleen Knight Abowitz  Dan Mamlok 《Educational theory》2020,70(6):731-748

In this essay, Kathleen Knight Abowitz and Dan Mamlok consider the arguments for agonist political education in light of a case study based in the events of the 2018 mass shooting at Stoneman Douglas High School in Parkland, Florida, and the subsequent activism of its survivors. We use this case to examine agonist expressions of citizenship, and to present an argument for framing agonist politics through the lens of Deweyan transactional communication combined with the critical concept of articulation. A major lesson in this case is the significance of citizenship learning that prioritizes challenging the political status quo along with working to reestablish new political relations on grounds that are more just. The authors argue that the endgame of agonist-informed political education should be that which helps students, as present and future citizens, reconstruct existing political conditions. Knight Abowitz and Mamlok conclude with suggestions for four domains of knowledge and capacities that can productively shape agonist citizenship education efforts: political education, lived citizenship, critical political literacies, and critical digital literacies.  相似文献   

Perceived efficacy and attitudes towards genetic science and science governance     

Knight T  Barnett J 《Public understanding of science (Bristol, England)》2010,19(4):386-402

Arguments for public involvement in science and technology are often based on ideas of developing a more capable public and the assumed effects this may have for science. However, such a relationship is yet to be sufficiently explored and recent work indicates that a more involved public may have counterintuitive effects. Using nationally representative survey data for the U.K. and Northern Ireland, the effects of the public's own beliefs about involvement are explored. Developing the concept of "belief in public efficacy," findings suggest those who believe that the public might be able to affect the course of decision making have less approving attitudes towards future applications of genetic science; however, an individual's political efficacy does not significantly influence these attitudes. Furthermore, political efficacy and belief in public efficacy have some distinct and opposing relationships with the principles of governance people prefer. Overall, findings provide support for suggestions that it is simplistic to consider increasing public involvement as a way of increasing the approval of risky new technologies.  相似文献   

Different but Equal? How Nonmajors and Majors Approach and Learn Genetics     

Jennifer K. Knight  Michelle K. Smith 《CBE life sciences education》2010,9(1):34-44

Introductory biology courses are frequently offered separately to biology majors and nonbiology majors, with the assumption that the two groups of students are different enough to merit different courses. To assess the evidence behind this assumption, we compared students in two different genetics classes at the University of Colorado–Boulder, one class for nonscience majors (nonmajors) and the other class for biology majors and students planning a biology-related career (majors), to see whether these two groups of students were fundamentally different in performance and attitudes. To measure content knowledge, we administered identical assessments to both groups of students during the semester: a validated pre- and postcontent assessment (Genetics Concept Assessment), ungraded quizzes after problem-solving sessions, and questions on each exam. We measured attitudes, study time, and study techniques through online surveys. Majors outperformed nonmajors on content assessments, finishing with significantly higher learning gains. Nonmajors and majors also differed in their motivation, interest, study time, and expert-level of beliefs. We suggest that focusing on the process of science and its connection to students'' lives will better engage and motivate nonmajors while still helping them learn the fundamental concepts of genetics.  相似文献   

A diagnostic assessment for introductory molecular and cell biology     

Shi J  Wood WB  Martin JM  Guild NA  Vicens Q  Knight JK 《CBE life sciences education》2010,9(4):453-461

We have developed and validated a tool for assessing understanding of a selection of fundamental concepts and basic knowledge in undergraduate introductory molecular and cell biology, focusing on areas in which students often have misconceptions. This multiple-choice Introductory Molecular and Cell Biology Assessment (IMCA) instrument is designed for use as a pre- and posttest to measure student learning gains. To develop the assessment, we first worked with faculty to create a set of learning goals that targeted important concepts in the field and seemed likely to be emphasized by most instructors teaching these subjects. We interviewed students using open-ended questions to identify commonly held misconceptions, formulated multiple-choice questions that included these ideas as distracters, and reinterviewed students to establish validity of the instrument. The assessment was then evaluated by 25 biology experts and modified based on their suggestions. The complete revised assessment was administered to more than 1300 students at three institutions. Analysis of statistical parameters including item difficulty, item discrimination, and reliability provides evidence that the IMCA is a valid and reliable instrument with several potential uses in gauging student learning of key concepts in molecular and cell biology.  相似文献
