Hypermedia learning environments (HLE) unevenly present new challenges and opportunities to learning processes and outcomes depending on learner characteristics and instructional supports. In this experimental study, we examined how one such HLE—MetaTutor, an intelligent, multi-agent tutoring system designed to scaffold cognitive and metacognitive self-regulated learning (SRL) processes—interacts with learner’s prior domain knowledge to affect their note-taking activities and subsequent learning outcomes. Sixty (N = 60) college students studied with MetaTutor for 120 min and took notes on hypermedia content of the human circulatory system. Log-files and screen recordings of learner-system interactions were used to analyze notes for several quantitative and qualitative variables. Results show that most note-taking was a verbatim copy of instructional content, which negatively related to the post-test measure of learning. There was an interaction between prior knowledge and pedagogical agent scaffolding, such that low prior knowledge students took a greater quantity of notes compared to their high prior knowledge counterparts, but only in the absence of MetaTutor SRL scaffolding; when agent SRL scaffolding was present, the note-taking activities of low prior knowledge students were statistically equivalent to the number of notes taken by their high prior knowledge counterparts. Theoretical and instructional design implications are discussed. 相似文献

This article revisits Paas and Van Merriënboer's (1993) measure of instructional efficiency, which can be applied by educational researchers to compare the effects of different instructional conditions on learning. This measure relied on performance and mental effort on the test, and as such gave an indication of the quality of learning outcomes. The acquisition of more (less) efficient cognitive schemata is indicated by combinations of high (low) performance and low (high) mental effort. This instructional efficiency measure has become widely adopted, but in an adapted form that incorporates mental effort invested in the learning phase instead of the test phase. This article demonstrates that the adaptation has important consequences for the construct of instructional efficiency and for the type of conclusions that can be drawn. Examples are given to illustrate the various implications of different combinations of mental effort and performance measures in the light of more contemporary developments in educational research. 相似文献

This study describes the development of three case studies that included a combination of multimedia production and instructional design skills within a particular setting. These case studies incorporated real-life incidents from 47 professional instructional designers. These instructional designers described a total of 146 activities involving instructional design and/or multimedia production activities. Employing an emergent theme analysis approach, nine distinct themes developed from these activities and were included in the case studies. These themes included: Collaboration; Diffusion of Innovations; Formative Evaluation; Instructional Design; Interactive Instruction; Learner Analysis; Online Instruction; Technical Infrastructure; and Video Solutions. Fifty-seven Instructional Design and Technology graduate students evaluated the effectiveness of these case studies and considered the case studies as being valuable in furthering their understanding of related multimedia production and instructional design activities. The intent of these case studies was to enable Instructional Design and Technology students to comprehend the relationship between multimedia production and instructional design activities. 相似文献

The purpose of this study was to test the effectiveness of a cognitive motivational model of course selection patterns to explain the continued participation of men and women in college science courses. A number of cognitive motivational constructs were analyzed in a path model and their effect on students' intention to continue in college chemistry was determined. Variables in the model included self-perceived ability in science, future expectations, level of past success, effort expended, subjective interpretations of both past success and task difficulty, and the intention to continue in college chemistry. The results showed no sex differences in course performance, the plan to continue in chemistry, perceived ability in science, or past achievement in science courses. The path analysis did confirm the usefulness of the cognitive motivational perspective to explain the intention of both men and women to continue in science. Central to that process appears to be a person's belief about their ability. Students who had confidence in their ability in chemistry expected to do well in the future and were more likely to take more chemistry. Ability ratings in turn were dependent on a number of past achievement experiences and the personal interpretation of those experiences. 相似文献

Promoting Acceleration of Comprehension and Content through Text (PACT) and similar team-based models directly engage and support students in learning situations that require cognitive elaboration as part of the processing of new information. Elaboration is subject to metacognitive control, as well (Karpicke, Journal of Experimental Psychology: General 138(4):469–485, 2009)—successful learners use metacognitive elaborative rehearsal to process and make sense of incoming information even in the absence of structured opportunities or instructional prompts for elaborating. Levels of processing and cognitive load theories suggest that students in PACT classrooms may outperform students in comparison classes because PACT engages and supports deep cognitive processing (via elaboration and discussion) at the time of learning, allowing participants to better conserve and more consistently reallocate cognitive and metacognitive resources (compared to students in the non-treated group) for encoding content. In other words, PACT may moderate the relationship of metacognitive elaborative rehearsal and content retrieval. Extant data from years 1 (n?=?419) and 2 (n?=?704) of the PACT/RFU project suggests such an effect. As hypothesized, there were no mean differences in reported metacognitive rehearsal use across the groups because metacognitive elaborative rehearsal was not taught. However, regression coefficients for content recall on metacognitive elaboration were greater in the treatment group in both samples suggesting that an instructional emphasis on deep processing leads to better content recall. The findings are discussed in the context of the Common Core State Standards and the large-scale testing programs in place currently across the USA. 相似文献

The determinants of stress in teaching were investigated in a context which allowed many of the characteristics of an educational system to be incorporated in the design. Using a specially developed self-report instrument, 545 secondary schoolteachers in Malta reported the perceived levels of stressfulness of 35 items covering various aspects of the teacher’s work environment. One-third of the respondents rated being a teacher as either very stressful or extremely stressful. A principal components analysis of the data on the 35 sources of stress yielded a four-factor structure described in terms of ‘pupil misbehaviour’, ‘poor working conditions’, ‘poor staff relations’ and ‘time pressures’. Repeated measures ANOVA of the factor scores revealed a number of significant two-way and three-way interactions involving the demographic variables of sex, age, type of teaching post, type of school selectivity, type of single-sex school, size of school, and type of curriculum subject/s taught. 相似文献

Effects of sex and strain on exploratory locomotion and development of nonreinforced maze patrolling
Continuous recording of locomotion in an enclosed maze with no reinforcement other than that intrinsic to ambulation through the maze provided evidence for a dissociation between the efficiency of patrolling the entire maze and locomotor activity. Patrolling efficiency improved with repeated exposure to a single maze or to two similar maze configurations but not with daily presentation of dissimilar mazes. There were only small strain and sex differences in the development of efficient patrolling, whereas locomotor activity was considerably higher in female Roman high-avoidance (RHA) rats than in female Roman low-avoidance rats and higher in RHA female rats than in RHA male rats. 相似文献

Job loss researchers have focused on the physical and mental well being of White working and middle class men, their families, friends, and coworkers to with immediate reemployment as the outcome. This study focused on low-income rural women dislocated workers and their decision to enroll in community college for retraining or seek immediate reemployment. Participants were 125 women (86 white, 39 African American; x = 42 years) who held a high school diploma or GED and who were laid off from manufacturing jobs within the last 2 years. Differences between two groups of women based on demographic variables and Transition Guide and Questionnaire-Modified (TGQ-M) scores were examined. The TGQ-M was developed to assess an individual's ability to cope with life transitions, based on Schlossberg's (1995) model of 4Ss (situation, self, supports, and strategies). One group enrolled in community college for retraining while the other group sought immediate reemployment. Findings revealed significant relationships between level of education and race/ethnicity and community college retraining. African-American women in this sample perceived themselves as having less support in coping with job loss. Women who chose community college had higher TGQ-M scores overall. Race/ethnicity and perception of support from others were the best predictors of community college retraining. Women, especially older women of color, have the hardest time finding quality employment after layoff. This study raised questions about the reasons why fewer African-American women in this sample enrolled in community college for retraining and had lower Supports scores than white women. Implications for counseling and future research are discussed. 相似文献

Equity is the most significant problem educators face. Very large inequities and inequalities persist in both education and society. Why? What can be done about them? While much has been written about these issues, progress is very slow and there is little agreement on why or what to do. While this article cannot resolve these questions, it raises five important issues concerning them: inter-agency contradictions concerning equity and global education policy; EFA and the MDGs; privatization and public-private partnerships; evidence-based policy; and the right to education. The article tackles the case of UNICEF, which has recently decided to focus its efforts on equity in education. In the conclusions which are drawn throughout, the article emphasizes the need for widespread, highly participative debates to answer the questions of why educators have made so little progress and what they can do to make more. 相似文献

As schools work to meet the ambitious Common Core State Standards in writing in the US, instructional approaches are likely to be examined (National Governors Association Center for Best Practices, Council of Chief State School Officers, 2010). However, there is little research on the current state of instruction. This study was designed to provide a comprehensive analysis of first-grade writing instruction across 13 schools in one state in the US. Daylong observations were conducted four times during the year in 50 first-grade classrooms. Using a time-sampled, observational protocol, observers coded multiple dimensions of instruction, including grouping, instructional focus, teacher instructional activity, and student writing activity. Results revealed that writing was taught for less than 30 min a day on average, and instruction in skills or process writing was common. Most instruction was organized in whole-class settings with teachers either presenting information or asking students questions. Variability in the amount and focus of writing instruction and in student writing activity was examined at the classroom and school levels. A small number of classrooms and schools were identified with distinctive patterns in their approach to instruction and writing activity. Several moderate relationships were found between the writing instructional focus and the nature of student writing. These findings suggest that first-grade writing instruction is inconsistent across classrooms and schools and point to instructional implications for teachers and schools in the US. 相似文献

This article looks at women teachers' involvement in educational reform from a gendered perspective. Using qualitative data collected in interviews with secondary level educators, the authors show how women teachers' beliefs and actions towards reform efforts were influenced by their gender identity. Socialization of women as nurturers and caretakers created in many women particular notions regarding the appropriate role they should play as teachers. When an educational reform effort 'fitted' with these conceptions, women teachers became advocates for and participated in the reforms. The support and commitment by women teachers in turn facilitated the success of the reforms. However, it was also found that the overrepresentation of women in a reform effort had the potential of creating negative political ramifications. When the character or profile of the reform took on a gendered identity, it ran the risk of facing resistance by men teachers in the school, ultimately thwarting implementation. 相似文献

This paper outlines extensions of Component Display Theory to provide the type of design guidance needed for experiential computer based instructional systems. The new Component Design Theory (CDT) extends the original theory in several significant ways. Content types are extended to content structures. These content structures include experiential as well as structural representations. Primary presentation forms are extended to primary presentation functions and the display is replaced by the transaction. Various types of transactions are identified for both structural and experiential representations. Course organization, previously described as Elaboration Theory, is included as part of the new CDT. Consistency rules are extended to include: (a) goal-content representation consistency; (b) goal/content representation-transaction consistency; and (c) goal/content representation-course organization consistency. Intervention rules are included for intra-transaction guidance, inter-transaction selection and sequence (strategy), inter-content representation selection and sequence (sequence) and control (who makes the guidance, strategy and sequence decisions, the learner or the system?). Finally a set of cardinal instructional principles is identified and the sets of rules which comprise the new CDT are suggested as prescribed procedures for implementing these cardinal principles. 1.

Three groups of college students were given instructions using different testing techniques to determine whether the superior performance obtained with Programmed Student Achievement (PA) was due to a Hawthorne Effect. PA students, operating under the consequence of failing the course if they failed to evidence criterion performance (100% mastery) on weekly quizzes, exhibited superior performance, relative to control groups, on the weekly quizzes and on an unannounced retention test. The results seem to preclude any attempt to interpret the effectiveness of Programmed Student Achievement on the basis of a Hawthorne Effect. 相似文献

This paper and the three which follow it, by Dijkstra, Klauer and Tennyson, are based upon a 1987 symposium of the American Educational Research Association: Metalearning theories and instructional design. This paper discusses the other three papers by posing the question “Are there any thinking skills?”, then considering points that need to be taken into account in arriving at a reasonable answer to this question. It concludes “There is thinking, and there are skills. But-are there any thinking skills?”. 相似文献
