Learner control in full and lean CAI programs     

Robert D. Hannafin  Howard J. Sullivan 《Educational technology research and development : ETR & D》1995,43(1):19-30

This study investigated the effects of two types of control over instruction (learner and program) and two modes of instructional programs (lean and full) on the achievement, option use, and time-in-program of 274 high-ability and low-ability students from grades 9 and 10. The basic instructional program in geometry was delivered by computer. Subjects under learner control scored significantly higher on the program posttest than those under program control, spent significantly more time in the program, and liked it better. Learner-control subjects appeared to “trust” their given version of the program, viewing many more optional screens in the full version than those in the lean one. High-ability learners adapted their study behavior to the lean version under learner control by choosing significantly more optional screens than their low-ability counterparts. This research was conducted while he was a graduate student at Arizona State University where Howard J. Sullivan is a professor in Learning and Instructional Technology.  相似文献   

Interstimulus interval determines whether ethanol produces conditioned place preference or aversion in mice     

Christopher L. Cunningham  Dobrina M. Okorn  Christine E. Howard 《Learning & behavior》1997,25(1):31-42

DBA/2J mice were exposed to a distinctive floor stimulus (CS+) and ethanol (2 g/kg) in a place conditioning paradigm. A different floor stimulus (CS?) was presented with saline. Mice injected just before or 30 min before CS exposure (Groups 0, ?30) showed conditioned place preference, whereas mice injected right after exposure to the CS (Group 5) displayed place aversion (Experiment 1). None of the other groups (?120, ?60, 15, 60) showed place conditioning. Handling and saline injection given just before or after CS exposure were unable to produce place conditioning (Experiment 2). However, there was a positive relationship between ethanol concentration (10% vs. 20%) and test performance, suggesting that peritoneal irritation influences place conditioning (Experiment 3). Overall, these findings support the suggestion that intraperitoneal injection of ethanol produces an initial short-duration aversive effect that is followed by a longer lasting positive motivational effect.  相似文献   

Exploring Engineering instructors’ views about writing and online tools to support communication in Engineering     

Sarah K. Howard  Maryam Khosronejad  Rafael A. Calvo 《European Journal of Engineering Education》2017,42(6):875-889

To be fully prepared for the professional workplace, Engineering students need to be able to effectively communicate. However, there has been a growing concern in the field about students’ preparedness for this aspect of their future work. It is argued that online writing tools, to engage numbers of students in the writing process, can support feedback on and development of writing in engineering on a larger scale. Through interviews and questionnaires, this study explores engineering academics’ perceptions of writing to better understand how online writing tools may be integrated into their teaching. Results suggest that writing is viewed positively in the discipline, but it is not believed to be essential to success in engineering. Online writing tools were believed to support a larger number of students, but low knowledge of the tools limited academics’ understanding of their usefulness in teaching and learning. Implications for innovation in undergraduate teaching are discussed.  相似文献   

Flavor- vs. tone-cued shock avoidance     

Howard B. Parker  Richard F. Smith 《Learning & behavior》1981,9(3):335-338

In a direct comparison, flavor-cued rats learned to avoid shock in a two-way shuttlebox as well as, or better than, tone-cued rats. These results stand in contrast to the prevalent view that rats encounter difficulty in forming flavor-shock, but not tone-shock, associations. In attempting to account for this contrast, we note that experiments revealing cue-modality specificity employ an aversion paradigm and record ingestive behavior. It is argued that both the paradigm and the dependent variable are inappropriate for assessing shock-avoidance learning, and that cue-modality specificity in such a setting reflects paradigm and response choice rather than a general characteristic of rats.  相似文献   

Pedagogy for partisanship: research training for Black graduate students in the Black intellectual tradition     

Joyce E. King  Thais M. Council  Janice B. Fournillier  Valora Richardson  Chike Akua  Natasha McClendon 《International journal of qualitative studies in education》2019,32(2):188-209

Current and former students of two professors in a southern research university and a community educator, all participants in an African-centered research collaborative/apprenticeship, describe what and how we study together and our struggle to use our knowledge and research in service to our community. We uplift the works of key Pan-African/Black/Africana Studies/Nile Valley scholars to illustrate the African epistemic foundation of our collaborative/apprenticeship. We describe how we utilized the methodology of narrative inquiry to explore our experiences as participants in the HeKA (Heritage Knowledge in Action) research collaborative and how HeKA has provided ways of knowing and being centered in our culture and heritage. We present our findings, which include some of the dilemmas of Black doctoral students and emerging scholars engaged in HeKA and how this collaborative/apprenticeship serves as an emancipatory praxis to enable the next generation to realize their goals of partisan research and pedagogy in higher education.  相似文献   

Brief Research Report: Bayesian Versus REML Estimations With Noninformative Priors in Multilevel Single-Case Data     

Eunkyeng Baek  S. Natasha Beretvas  Wim Van den Noortgate  John M. Ferron 《Journal of Experimental Education》2020,88(4):698-710

Abstract

Recently, researchers have used multilevel models for estimating intervention effects in single-case experiments that include replications across participants (e.g., multiple baseline designs) or for combining results across multiple single-case studies. Researchers estimating these multilevel models have primarily relied on restricted maximum likelihood (REML) techniques, but Bayesian approaches have also been suggested. The purpose of this Monte Carlo simulation study was to examine the impact of estimation method (REML versus Bayesian with noninformative priors) on the estimation of treatment effects (relative bias, root mean square error) and on the inferences about those effects (interval coverage) for autocorrelated multiple-baseline data. Simulated conditions varied with regard to the number of participants, series length, and distribution of the variance within and across participants. REML and Bayesian estimation led to estimates of the fixed effects that showed little to no bias but that differentially impacted the inferences about the fixed effects and the estimates of the variances. Implications for applied researchers and methodologists are discussed.  相似文献   

Effects of group rearing on the control exerted by an imprinting stimulus     

Stephen J. Gaioni  Peter DePaulo  Howard S. Hoffman 《Learning & behavior》1980,8(4):673-678

Prior research suggests that group rearing may attenuate a young bird’s tendency to approach and follow an imprinting stimulus. The present work examined the effect of group rearing on a different measure of attachment, suppression by the imprinting stimulus of distress calling induced by abrupt reductions in group size. In Experiment 1, ducklings were reared in groups of 12 or 3 over Days 1–6 posthatch, and each group received a total of 3.5 h of exposure to an imprinting stimulus. Subsequent tests revealed that, when the groups of ducklings were separated into smaller subgroups: (1) the fewer the ducklings in a subgroup, the more distress calls emitted; (2) a given number of birds separated from a larger group emitted more distress calls than an equal number from a smaller group; and (3) regardless of the subgroup size, fewer distress calls occurred when the imprinting stimulus was present than when it was absent. A second experiment revealed that when a group of 12 birds was first confronted with an imprinting stimulus on Day 6 posthatch, they reacted with an increase in distress calling and corner huddling (an aversive reaction). After several hours of exposure to the stimulus, however, its presence exerted a powerful suppressive effect on distress calling. It is concluded that the social bonds between the members of a brood do not preclude the formation of a social attachment to an imprinting stimulus subsequently encountered.  相似文献   

Maternal Representations of Attachment during Pregnancy Predict the Organization of Infant-Mother Attachment at One Year of Age   总被引：4，自引：0，他引：4  

Peter Fonagy  Howard Steele  Miriam Steele 《Child development》1991,62(5):891-905

While strong retrospective and concurrent associations between maternal and infant patterns of attachment have been noted, this is one of the first reports of a prospective investigation of such associations. The Adult Attachment Interview was administered to 100 mothers expecting their first child, and, at 1-year follow-up, 96 of these were seen with their infants at 12 months in the Strange Situation. Maternal representations of attachment (autonomous vs. dismissing or preoccupied) predicted subsequent infant-mother attachment patterns (secure vs. insecure) 75% of the time. These observed concordances, as well as the discordances, are discussed in terms of the uniquely powerful contribution the Adult Attachment Interview makes to the study of representational and intergenerational influences on the development of the infant-mother attachment.  相似文献   

Acquisition of behavioral control by the auditory features of an imprinting object     

Leonard A. Eiserer  Howard S. Hoffman 《Learning & behavior》1974,2(4):275-277

Presentations of a visible moving object immediately suppressed ongoing distress vocalization in newly hatched ducklings, but presentations of only the auditory features of the object initially had no effect. However, as the ducklings received more and more exposure to the visible moving object, the object’s auditory features gradually acquired the ability to suppress distress calls themselves. These auditory features failed to develop suppressive properties in ducklings which received prolonged exposure to those features but never saw the object in motion. The gradual acquisition of behavioral control by the auditory features of a moving object is taken to represent the essence of the imprinting process.  相似文献
