The objective of the three studies presented here was to investigate how situational interest is related to knowledge acquisition. Situational interest is construed as a motivational response to a perceived knowledge deficit. It is triggered in situations where this knowledge deficit becomes manifest, such as in the confrontation with a problem. In Study 1 we manipulated prior knowledge of 32 secondary-school students about a particular problem (i.e., reasons for the conquest of Singapore by the Japanese during the Second World War). Only students who lacked the appropriate knowledge showed an increase in situational interest after the problem was presented. In Study 2 (N = 60), students who showed awareness that they lacked knowledge to understand a problem (i.e., causes of erosion of an island) showed increased situational interest in that problem. In Study 3 (N = 86), situational interest and knowledge acquisition were monitored over the course of a 3-h lesson in a natural classroom. We were able to demonstrate that situational interest decreased with increasing knowledge of the problem-at-hand. We argue that the findings support a knowledge-deprivation account of situational interest. Our findings are at variance with the broadly held conviction that situational interest and knowledge necessarily influence each other positively.  相似文献

Are preservice teachers prepared to teach struggling readers?   总被引:1,自引:0,他引:1  
Reading disabilities such as dyslexia, a specific learning disability that affects an individual’s ability to process written language, are estimated to affect 15–20% of the general population. Consequently, elementary school teachers encounter students who struggle with inaccurate or slow reading, poor spelling, poor writing, and other language processing difficulties. However, recent evidence may suggest that teacher preparation programs are not providing preservice teachers with information about basic language constructs and other components related to scientifically based reading instruction. As a consequence preservice teachers have not exhibited explicit knowledge of such concepts in previous studies. Few studies have sought to assess preservice teachers’ knowledge about dyslexia in conjunction with knowledge of basic language concepts. The purpose of the present study was to examine elementary school preservice teachers’ knowledge of basic language constructs and their perceptions and knowledge about dyslexia. Findings from the present study suggest that preservice teachers, on average, are able to display implicit skills related to certain basic language constructs (i.e., syllable counting), but fail to demonstrate explicit knowledge of others (i.e., phonics principles). Also, preservice teachers seem to hold the common misconception that dyslexia is a visual perception deficit rather than a problem with phonological processing. Implications for future research as well as teacher preparation are discussed.  相似文献

It is widely accepted that general intelligence and phonological awareness contribute to children’s acquisition of reading and spelling skills. A further candidate in this regard is orthographic knowledge (i.e., the knowledge about permissible letter patterns). It consists of two components, word-specific (i.e., the knowledge of the spelling of specific words) and general orthographic knowledge (i.e., the knowledge about legal letter patterns of a writing system). Among German students, previous studies have shown that word-specific orthographic knowledge contributes to both reading and spelling. The results regarding general orthographic knowledge and its contribution to reading and spelling are inconsistent. The major goal of the present study was to determine the incremental predictive value of orthographic knowledge for reading and spelling skills among German elementary-school children (N = 66), over and above the contribution of general intelligence and phonological awareness. The second goal was to examine whether there is a difference between the two subtypes of orthographic knowledge in the amount of their respective contribution to reading and spelling performance. The results show that word-specific as well as general orthographic knowledge contribute to both reading and spelling performance, over and above intelligence and phonological awareness. Furthermore, it reveals that both word-specific and general orthographic knowledge explain more variance of spelling compared to reading. Possible explanations for these results, limitations, and implications of the study are being discussed.

Researchers have argued against deficit-based explanations of students’ difficulties with mathematical sense-making, pointing instead to factors such as epistemology. Students’ beliefs about knowledge and learning can hinder the activation and integration of productive knowledge they have. Such explanations, however, risk falling into a ‘deficit trap’—substituting a concepts/skills deficit with an epistemological one. Our interview-based case study of a freshman engineering major, ‘Jim,’ explains his difficulty solving a physics problem (on hydrostatic pressure) in terms of his epistemology, but avoids a deficit trap by modeling the dynamics of his epistemological stabilities and shifts in terms of fine-grained cognitive elements that include the seeds of epistemological expertise. Specifically, during a problem-solving episode in the interview, Jim reaches and sticks with an incorrect answer that violates common sense. We show that Jim has all the mathematical skills and physics knowledge he would need to resolve the contradiction. We argue that his difficulty doing so stems in part from his epistemological views that (i) physics equations are much more trustworthy than everyday reasoning, and (ii) physics equations do not express meaning that tractably connects to common sense. For these reasons, he does not view reconciling between common sense and formalism as either necessary or plausible to accomplish. But Jim’s in-the-moment shift to a more sophisticated epistemological stance highlights the seeds of epistemological expertise that were present all along: he does see common sense as connected to formalism (though not always tractably so), and in some circumstances, this connection is both salient and valued.  相似文献

This paper explores the different types and characteristics of preschool children's explanations of plant growth and rain formation. The children's explanations were categorized as naturalistic, non-naturalistic, or synthetic, i.e., explanations containing both naturalistic and non-naturalistic parts. In regards to plant growth the children tended to rely on synthetic or on naturalistic explanations, which involved direct and indirect agents (such as water, a person, fertilizers, roots) enabling the plant to grow. Non-naturalistic explanations of plant growth, or the non-naturalistic parts of synthetic explanations, were mainly animistic (anthropomorphic). In the case of rain formation the children most frequently used non-naturalistic explanations, which were mainly teleological or metaphysical. The naturalistic explanations recorded on rain formation, as well as the naturalistic parts of synthetic explanations tended to have a non-agentive character, i.e., children considered rainwater as preexisting in containers such as the clouds. Overall, the explanations recorded about plant growth tended to be more complex than the ones for rain formation. It is suggested that science activities designed for preschool children should take into account the types and characteristics of their explanations in order to select which phenomena are appropriate for this age group, and aim at fostering the children's ability at formulating naturalistic explanations.  相似文献

Example-based learning often follows a design in which learners first receive instructional explanations that communicate new principles and concepts and second examples thereof. In this setting, using the knowledge components of the instructional explanations to explain the examples (i.e., generating principle-based self-explanations) is considered to be a highly important learning process. However, a potential suboptimality of this learning process is that it scarcely requires learners to organize the content of the instructional explanations into coherent mental representations. Thus, in two experiments we investigated whether prompting learners to organize the content of the instructional explanations before providing them with the examples (and self-explanation prompts) enhances the effectiveness of example-based learning. We consistently found that organization prompts fostered learning regardless of whether the learners also received self-explanation prompts. Hence, in example-based learning, learners should be prompted to not only generate principle-based self-explanations but also to organize the content of the instructional explanations.  相似文献

Animated models use animations and explanations to teach how a problem is solved and why particular problem-solving methods are chosen. Often spoken explanations are proposed to accompany animations in order to prevent overloading the visual channel (i.e., the modality effect). In this study we adopt the hypothesis that the inferior performance of written text compared to spoken text is due to the fact that written text receives less attention and, consequently, less effortful processing. In a 2 × 2 factorial experiment (N = 96) with the factors modality (written, spoken) and reflection (reflection prompts, no reflection prompts) the hypothesis is tested that prompted reflection requires learners to explicitly attend to written explanations and carefully process them, thus yielding higher transfer performance, whereas for spoken explanations prompted reflection would have no effect on transfer performance. The results indeed showed the hypothesized interaction between modality and reflection prompts. They suggest that the modality effect can be compensated for when learners explicitly attend to the information and effortfully process it. This has implications for learning situations in which spoken explanations are no option, such as education for the hearing-impaired.  相似文献

Young Children's Understanding of the Mind-Body Distinction   总被引:3,自引:0,他引:3  
4 experiments investigated children's understanding of the mind-body distinction. Children of ages 4 and 5 recognized not only the differential modifiability of changeable versus unchangeable human properties and bodily versus mental properties, but also the independence of activities of bodily organs from a person's intention (Experiment 1). When presented 3 types of causal explanations (i.e., intentional, vitalistic, mechanical), 6-year-olds chose most often as most plausible for bodily functions vitalistic explanations (i.e., those ascribing the phenomena to a relevant bodily organ's initiative and effortful engagement in activity); 8-year-olds chose the vitalistic explanations second most often, following mechanical ones (Experiment 2). However, 6-year-olds, as well as 8-year-olds and adults, did not always choose vitalistic explanations over intentional explanations (Experiment 3); whereas they tended to prefer vitalistic explanations for biological phenomena, they predominantly accepted intentional ones for psychological phenomena (Experiment 3A). These results suggest that children as young as 6 years of age have acquired a form of biology as an autonomous domain which is separate from that of psychology.  相似文献

The development of visual expectations in the first year   总被引:1,自引:0,他引:1  
The development of expectations was investigated by using the Visual Expectations Procedure. In Experiment 1, 128 infants aged 6-, 9-, and 12-months-old saw two 40-trial sequences of a videotaped mechanical toy appearing in various locations. The sequences represented an alternation pattern (i.e., ABAB) or a complex pivot pattern (i.e., ABCBABCB). In Experiment 2, 76 infants aged 4-, 8-, and 12-months-old saw either a left-right alternation or a top-bottom alternation. Reaction time improved and the percentage of anticipations increased between 6 and 9 months in Experiment 1 and between 4 and 8 months in Experiment 2 but not thereafter. Anticipations for the pivot sequence and for younger infants on both sequences were often incorrect (i.e., gaze shifts occurred before stimulus onset but were not directed toward the upcoming stimulus). We conclude that young infants have expectations that reflect some degree of general or procedural knowledge, but it is not clear that this behavior implies specific, articulated expectations about upcoming events.  相似文献

The goal of the present study was to continue to build and refine the Opportunity-Propensity (O-P) model of achievement by using it to explain well-known achievement disparities between schools that differ in terms of their racial and ethnic composition. The O-P model categorizes predictors into antecedent factors (e.g., family SES, parent educational aspirations), opportunity factors (e.g., content coverage and teaching style), and propensity factors (e.g., prior knowledge and motivation). To refine the model further, the authors did the following: (a) added predictors in each category that have not been examined to date; (b) used hierarchical linear modeling to explain growth in knowledge between two assessment points; (c) identified similarities and differences in the models for two content areas (i.e., math and reading); and (d) identified similarities and differences in the models for two age levels (i.e., 3rd grade and 8th grade). Results showed that the combination of new and established predictors accounted for approximately 50% of the variance in the rate at which knowledge grew in both math and reading at both age levels. In addition, the variance explained by the racial and ethnic composition of schools when this variable was entered as the sole predictor of achievement was substantially reduced after antecedent, opportunity, and propensity factors were entered in subsequent models. However, the coefficients for certain school compositions remained significant even after such controls, and the models differed somewhat between content areas (math and reading), and age levels (3rd and 8th grade). Findings are discussed in terms of the implications of these results for building and refining the O-P model further.  相似文献

Previous research has shown that writers and editors of all ages and abilities have trouble correcting errors in texts. In this study, we were interested in discovering whether people do not correct these errors mainly because (1) they do not have the knowledge to correct them, or because (2) even though they do have the knowledge to correct the errors, they do not use it. The first case would point to aknowledge deficit, or a deficit at the cognitive level; the second case would point to aprocessing deficit, or a deficit at the metacognitive level. The study compared the number and type of implanted errors corrected by high school and college subjects working on two different texts under three different conditions. We found that, for both ages, the biggest stumbling block in correcting errors was not the knowledge of how to correct them, but rather a failure to detect them: They did not use their available knowledge to find the errors. This processing deficit may be the result of a dearth of available error-finding strategies, or knowledge may not be activated because of lack of motivation or because of a failure to perceive the nature of the task.  相似文献

In this study of the project DyAdd, implicit learning was investigated through two paradigms in adults (18–55 years) with dyslexia (n?=?36) or with attention deficit/hyperactivity disorder (ADHD, n?=?22) and in controls (n?=?35). In the serial reaction time (SRT) task, there were no group differences in learning. However, those with ADHD exhibited faster RTs compared to other groups. In the artificial grammar learning (AGL) task, the groups did not differ from each other in their learning (i.e., grammaticality accuracy or similarity choices). Further, all three groups were sensitive to fragment overlap between learning and test-phase items (i.e., similarity choices were above chance). Grammaticality performance of control participants was above chance, but that of participants with dyslexia and participants with ADHD failed to differ from chance, indicating impaired grammaticality learning in these groups. While the main indices of AGL performance, grammaticality accuracy and similarity choices did not correlate with the neuropsychological variables that reflected dyslexia-related (phonological processing, reading, spelling, arithmetic) or ADHD-related characteristics (executive functions, attention), or intelligence, the explicit knowledge for the AGL grammar (i.e., ability to freely generate grammatical strings) correlated positively with the variables of phonological processing and reading. Further, SRT reaction times correlated positively with full scale intelligence quotient (FIQ). We conclude that, in AGL, learning difficulties of the underlying rule structure (as measured by grammaticality) are associated with dyslexia and ADHD. However, learning in AGL is not related to the defining neuropsychological features of dyslexia or ADHD. Instead, the resulting explicit knowledge relates to characteristics of dyslexia.  相似文献

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.  相似文献

Using a sample of college students (N = 301), this study examined students' attributions about and explanations for teachers' expressions of anger in the classroom. These displays of anger were evaluated based on the extent to which they were aggressive (e.g., Distributive or Passive) or assertive (e.g., Integrative). Consistent with the fundamental attribution error, students assigned internal attributions to teachers who used Distributive Aggression (e.g., yell and scream) and Passive‐Aggression (e.g., show anger with cold looks) to a greater extent than teachers who were Assertive (i.e., calmly discuss the problem with the students). When students were asked to identify why they thought their teacher was angry, the overwhelming majority of reasons involved student‐related problems. In fact, the most frequently cited reason was Student Misbehaviors followed by Lack of Student Effort. Surprisingly, students acknowledge that something they did triggered the teacher's display of anger; however, consistent with fundamental attribution error, students still attributed the teacher's expression of anger to internal causes. The implications of these findings for negative emotional expressions in the instructional context in particular and for teacher‐student relationships in general are discussed.  相似文献

The authors discuss the cultural relativism of enuresis and the subsequent notion that urinary incontinence may not be a disease or psychopathy, but, rather, a problem associated with social expectations and developmental delays. Published literature has revealed that, historically, enuretic children have been subjected to distressing and painful methods of treatment, i. e., medications, mechanical devices, and pharmacologic preparations, to the point of permanent disability. They also discuss the evolution of explanations and treatments for enuresis from the Middle Ages into the 1970s, with emphasis on the successful use of behaviral therapies and meaningful parent and child reeducation.  相似文献

Recent research has shown that example study only (EE) and example-problem pairs (EP) were more effective (i.e., higher test performance) and efficient (i.e., attained with less effort invested in learning and/or test tasks) than problem-example pairs (PE) and problem solving only (PP). We conducted two experiments to investigate how different example and problem-solving sequences would affect motivational (i.e., self-efficacy, perceived competence, and topic interest) and cognitive (i.e., effectiveness and efficiency) aspects of learning. In Experiment 1, 124 technical students learned a mathematical task with the help of EEEE, EPEP, PEPE, or PPPP and then completed a posttest. Students in the EEEE Condition showed higher posttest performance, self-efficacy, and perceived competence, attained with less effort investment, than students in the EPEP and PPPP Condition. Surprisingly, there were no differences between the EPEP and PEPE Condition on any of the outcome measures. We hypothesized that, because the tasks were relevant for technical students, starting with a problem might not have negatively affected their motivation. Therefore, we replicated the experiment with a different sample of 81 teacher training students. Experiment 2 showed an efficiency benefit of EEEE over EPEP, PEPE, and PPPP. However, only EEEE resulted in greater posttest performance, self-efficacy, and perceived competence than PPPP. We again did not find any differences between the EPEP and PEPE Condition. These results suggest that, at least when short training phases are used, studying examples (only) is more preferable than problem solving only for learning. Moreover, this study showed that example study (only) also enhances motivational aspects of learning whereas problem solving only does not positively affect students’ motivation at all.  相似文献

Beliefs About Academic Knowledge   总被引:9,自引:0,他引:9  
Individuals' beliefs about knowledge (i.e., epistemological beliefs) have become the focus of inquiry in the educational and psychological literatures. Based on an analysis of those literatures, we first propose that epistemological beliefs are multidimensional and multilayered. That is, individuals possess general beliefs about knowledge, as well as beliefs about more specific forms of knowledge (e.g., academic knowledge). Second, we examine the relationship between epistemological beliefs and learning in order to understand why such beliefs are important to educators. Third, we question whether beliefs about academic knowledge are truly general (i.e., unwavering across academic domains) or have a character reflective of the domain to which they are associated (i.e., domain specific). Finally, we explore some of the common problems in the research and suggest topics for future study.  相似文献

Extinction-induced attenuation of single-phase and two-phase blocking was examined with rats in a conditioned lick-suppression task. In Experiment 1, which compared the effectiveness of single- and two-phase blocking, it was found that single-phase blocking was facilitated by the initiation of training with an A-US trial rather than an AX-US trial. Single-phase (but not two-phase) blocking was attenuated as a result of 200 extinction trials with the blocking stimulus (Experiment 2). Experiment 3 revealed recovery from two-phase blocking after 800 extinction trials with the blocking stimulus. Recovery from both types of blocking was specific to the blocked CS trained in compound with the extinguished stimulus (Experiment 4). This is the first article to report that the blocking deficit can be reversed by extinguishing the blocking stimulus. These results are discussed in light of acquisition models (i.e., retrospective revaluation) and expression models (i.e., the comparator hypothesis).  相似文献

The concept map is becoming a ubiquitous tool in education. In recent years there has been a growing interest in “diagramming” or “mapping” ideas to be learned (e.g., Jonassen et al., 1998). The approach has been championed by study skills proponents such as Buzan (1993). Maps of concepts and relationships have been used by many researchers and practitioners to help diagnose misunderstanding, improve study methods and glimpse how learners come to know. In other areas, the representation of knowledge in formalisms such as the Net greatly assisted the development of intelligent tutoring systems (e.g., Sowa, 1983). In order to better understand the claims made for its efficacy, reference to how concept maps have been used and defined will lead to a plausible explanation of the process of “off–loading” of concepts during learning or study (McAleese, 1994, 1998). In order to demonstrate the widespread application of supporting learn ers with external “learning spaces” (c.f. ISLEs/ and REALs—Grabinger et al., 1998; Grabinger & Dunlap, 1995; MacFarlane, 1993), consideration will be given in this paper to techniques that formally represent knowledge in Concept–Relationship–Concept “instances” (Fisher et al., 1990). Other techniques such as reflection journals draw on the same process but are not considered in detail here. The importance of self regulation (Zimmerman, 1990) and self-confrontation (McAleese, 1985) is highlighted in this framework. The map as a mirror or an assistant to learners is well documented (e.g., Vizcarro & Leon, 1998); the question of an external representation of thinking, in the form of a map determining what can be learned as well as what might be learned, is not yet fully known.  相似文献
