Troubleshooting in a practice situation requires two types of information, namely for reasoning about the problem-cause and for finding an adequate solution (declarative information) and for manipulating the environment (procedural information). It is hypothesized that presenting this information piece-by-piece during practice (i.e., presentation of declarative and procedural information separately) frees up working memory and facilitates learning. Moreover, this effect is augmented when both information types are presented just-in-time (i.e., declarative information before practice and procedural information during practice). This should yield highest test performance and instructional efficiency, which is defined as higher test performance combined with lower mental effort during practice. Eighty-five students (49 male, 36 female; M = 15.2 years, SD = .59) participated in a 2 × 2 factorial experiment with the factors timing of declarative information and timing of procedural information, both before or during practice. Transfer test scores and transfer efficiency scores support the first hypothesis; the second hypothesis was not supported.  相似文献

This study used a sequential set-up to investigate the consecutive effects of timing of supportive information presentation (information before vs. information during the learning task clusters) in interactive digital learning materials (IDLMs) and type of collaboration (personal discussion vs. online discussion) in computer-supported collaborative learning (CSCL) on student knowledge construction. Students (N = 87) were first randomly assigned to the two information presentation conditions to work individually on a case-based assignment in IDLM. Students who received information during learning task clusters tended to show better results on knowledge construction than those who received information only before each cluster. The students within the two separate information presentation conditions were then randomly assigned to pairs to discuss the outcomes of their assignments under either the personal discussion or online discussion condition in CSCL. When supportive information had been presented before each learning task cluster, online discussion led to better results than personal discussion. When supportive information had been presented during the learning task clusters, however, the online and personal discussion conditions had no differential effect on knowledge construction. Online discussion in CSCL appeared to compensate for suboptimal timing of presentation of supportive information before the learning task clusters in IDLM.  相似文献

Two different methods of practice are available in the learning of simple information, test practice or study practice. Of these two methods of learning, research has generally shown that test practice is superior to study practice. However, this research has not considered the testing advantage with respect to the fact that test learning is uncertain (i.e. if recall fails, nothing appears to be learned) or with respect to the fact that study learning depends greatly on the duration of the study event. The following work clarifies these issues by presenting an integrated computational model of the relative costs and benefits of testing compared to study presentation [based on the ACT-R theory of declarative memory; Anderson, J.R. & Schooler, L.J. (1991). Psychological Science 2: 396–408; Pavlik Jr., P.I.. & Anderson, J.R. (2005). Cognitive Science 29: 559–586]. This model was applied to determine how test and study practice can be optimally employed to improve learning and provides a framework for understanding the effects of mnemonic strategies in simple memory tasks.  相似文献

The present study investigated 3‐ to 7‐year‐olds' (N = 91) comprehension of two‐clause sentences containing the temporal connectives before or after. The youngest children used an order of mention strategy to interpret the relation between clauses: They were more accurate when the presentation order matched the chronological order of events: “He ate his lunch, before he played in the garden” (chronological) versus “Before he played in the garden, he ate his lunch” (reverse). Between 4 and 6 years, performance was influenced by a combination of factors that influenced processing load: connective type and presentation order. An independent measure of working memory was predictive of performance. The study concludes that the memory demands of some sentence structures limits young children's comprehension of sentences containing temporal connectives.  相似文献

This study investigated the effects of presenting domain information (basic information about the domain) either together with or instead of offering exploratory practice (an exploratory opportunity in a simulation-based representation of the learning domain) prior to inquiry learning for facilitating students' hypothesis generation and subsequent inquiry processes and their knowledge acquisition. Secondary school students (n = 118) completed a simulation-based inquiry task on force and motion. They were randomly assigned to one of four conditions: the D + E condition (n = 29), in which domain information and exploratory practice were available; the D condition (n = 30), in which only domain information was available; the E condition (n = 32), in which only exploratory practice was available; or the C condition (n = 27), with no support at all. Students' knowledge was measured with a pre- and posttest and a test on knowledge of variables. Inquiry processes were inferred from information students entered in a Hypothesis Scratchpad and an Observation tool, and from a final summary that they had to write. Results indicated that providing students with domain information alone helps to foster their knowledge of variables before generating hypotheses and leads to knowledge acquisition. The results also showed that the opportunity to explore before experimenting does not affect students' inquiry behavior or learning performance, even when combined with providing students with domain information.  相似文献

Previous research has demonstrated benefits of interleaved practice over blocked practice for learning mathematical formulas. This experiment tested whether the benefits from interleaved practice would generalize to more complex problems, where the problem type must be inferred from information in the problem. We compared delayed test performance of participants assigned to blocked practice to participants assigned to interleaved practice who had high or low practice performance. University students (Mage = 18.97, SDage = 1.50, 64% female) learned how to solve probability word problems in blocked practice, interleaved practice, or hybrid conditions that included both kinds of practice. Conditions that included some interleaved practice outperformed a condition that included only blocked practice at delayed test. Participants with high performance on interleaved practice problems outperformed participants assigned to blocked practice at delayed test. These results suggest that interleaved practice can confer learning advantages even for more complex problems.  相似文献

This study investigated the cognitive processes involved in learning information presented in multimedia and text format using electroencephalographic (EEG) measures. Thirty-eight students (19 gifted, and 19 average) learned material presented with text (text); text, sound, and picture (picture); and text, sound and video (video), while their EEG was recorded. Alpha power, which is inversely related to mental effort, was analyzed. For thetext presentation, the alpha power measures showed higher amplitudes (less mental activity) over the occipital and temporal lobes, and less alpha power (higher mental activity) over the frontal lobes. The results support the assumption that thevideo andpicture presentations induced visualization strategies, whereas thetext presentation mainly generated processes related to verbal processing. The results further showed that gifted students displayed less mental activity during all three formats of presentation. These differences were especially pronounced for thevideo format. No gender-related differences in EEG patterns related to the format of presentation were observed.  相似文献

Retrieval practice has been shown to benefit learning. However, the benefit has sometimes been attenuated with more complex materials that require integrating multiple units of information. Critically, Tran et al. Psychonomic Bulletin & Review, 22, 135–140 (2015) found that retrieval practice improves sentence memory but not the drawing of inferences from the same sentences. In three experiments, we investigated whether this lack of benefit of retrieval practice for inferential ability was due to the presentation format of the material. Participants studied four sets of seven to nine related sentences by practicing retrieval for two sets and rereading the other two sets. A final test was given 2 days later. When sentences were presented one at a time during study/practice as in Tran et al., we found no effect of retrieval practice on a test requiring inferential reasoning. When sentences in a set were presented simultaneously during study/practice, retrieval practice in the form of fill-in-the-blank testing (experiments 1 and 2) and free recall (experiment 3) aided later deductive inference more than rereading. Our findings suggest that retrieval practice can improve deductive inference, but in order to optimize its utility, the format in which the material is presented during practice must not hinder relational processing of the individual sentences.  相似文献

Many new methods have contributed to the learning of anatomy, including several interactive methods, increasing the effectiveness of educational programs. The effectiveness of an educational program involving several interactive learning methods such as problem-based learning and reciprocal peer teaching was researched in this study. A quasi-experimental before–after study on three consecutive groups of second-year students at the Grenoble School of Medicine was conducted. The lectures were replaced by an educational program based on the problem-based learning method and reciprocal peer teaching. The first session was dedicated to reading clinical cases illustrating the medical concept, so that the learning objectives for the second session could be set. Then, after viewing digital courses, the second session was dedicated to a synthetic presentation by the students themselves, followed by an interactive summary with the teacher. The analysis of 630 students showed a significant increase in the theory test results for those who took part in the intervention: 9.71 versus 9.19 (β = 0.57, P = 0.036). Moreover, satisfaction was high after the intervention (mean = 4.5/5), and when comparing the two pedagogical approaches the students showed a clear preference for the program implemented with the concepts highlighted such as interactivity, in-depth work, group work, and autonomy. A multifaceted interactive pedagogy program could have a significant impact on the results of the theoretical concepts presented and on satisfaction as well as increased investment by students in learning anatomy.  相似文献

This study developed three forms of computer-based multimedia, including Static Graphics (SG), Simple Learner-Pacing Animation (SLPA), and Full Learner-Pacing Animation (FLPA), to assist students in learning topographic measuring. The interactive design of FLPA allowed students to physically manipulate the virtual measuring mechanism, rather than passively observe dynamic or static images. The students were randomly assigned to different multimedia groups. The results of a one-way ANOVA analysis indicated that (1) there was a significant difference with a large effect size (f = .69) in mental effort ratings among three groups, and the post-hoc test indicated that FLPA imposed less cognitive load on students than did SG (p = .007); (2) the differences of practical performance scores among groups reached the statistic significant level with a large effect size (f = .76), and the post-hoc test indicated that FLPA fostered better learning outcomes than both SLPA and SG (p = .004 and p = .05, respectively); (3) the difference in instructional efficiency that was computed by the z-score combination of students’ mental effort ratings and practical performance scores among the three groups obtained the statistic significant level with a large effect size (f = .79), and the post-hoc test indicated that FLPA brought students higher instructional efficiency than those of both SLPA and SG (p = .01 and .005, respectively); (4) no significant effect was found in instructional time-spans between groups (p = .637). Overall, FLPA was recommended as the best multimedia form to facilitate topographic measurement learning. The implications of instructional multimedia design were discussed from the perspective of cognitive load theory.  相似文献

Recent research has touted the benefits of learner-centered instruction, problem-based learning, and a focus on complex learning. Instructors often struggle to put these goals into practice as well as to measure the effectiveness of these new teaching strategies in terms of mastery of course objectives. Enter the course evaluation, often a standardized tool that yields little practical information for an instructor, but is nonetheless utilized in making high-level career decisions, such as tenure and monetary awards to faculty. The present researchers have developed a new instrument to measure teaching and learning quality (TALQ). In the current study of 464 students in 12 courses, if students agreed that their instructors used First Principles of Instruction and also agreed that they experienced academic learning time (ALT), then students were about 5 times more likely to achieve high levels of mastery of course objectives and 26 times less likely to achieve low levels of mastery, according to independent instructor assessments. TALQ can measure improvements in use of First Principles in teaching and course design. The feedback from this instrument can assist teachers who wish to implement the recommendation made by Kuh et al. (2007) that universities and colleges should focus their assessment efforts on factors that influence student success.  相似文献

This study examined whether practice testing with short-answer (SA) items benefits learning over time compared to practice testing with multiple-choice (MC) items, and rereading the material. More specifically, the aim was to test the hypotheses of retrieval effort and transfer appropriate processing by comparing retention tests with respect to practice testing format. To adequately compare SA and MC items, the MC items were corrected for random guessing. With a within-group design, 54 students (mean age = 16 years) first read a short text, and took four practice tests containing all three formats (SA, MC and statements to read) with feedback provided after each part. The results showed that both MC and SA formats improved short- and long-term memory compared to rereading. More importantly, practice testing with SA items is more beneficial for learning and long-term retention, providing support for retrieval effort hypothesis. Using corrections for guessing and educational implications are discussed.  相似文献

In the context of gross anatomy education, novel augmented reality (AR) systems have the potential to serve as complementary pedagogical tools and facilitate interactive, student-centered learning. However, there is a lack of AR systems that enable multiple students to engage in collaborative, team-based learning environments. This article presents the results of a pilot study in which first-year medical students (n = 16) had the opportunity to work with such a collaborative AR system during a full-day gross anatomy seminar. Student performance in an anatomy knowledge test, conducted after an extensive group learning session, increased significantly compared to a pre-test in both the experimental group working with the collaborative AR system (P < 0.01) and in the control group working with traditional anatomy atlases and three-dimensional (3D) models (P < 0.01). However, no significant differences were found between the test results of both groups. While the experienced mental effort during the collaborative learning session was considered rather high (5.13 ± 2.45 on a seven-point Likert scale), both qualitative and quantitative feedback during a survey as well as the results of a System Usability Scale (SUS) questionnaire (80.00 ± 13.90) outlined the potential of the collaborative AR system for increasing students' 3D understanding of topographic anatomy and its advantages over comparable AR systems for single-user experiences. Overall, these outcomes show that collaborative AR systems such as the one evaluated within this work stimulate interactive, student-centered learning in teams and have the potential to become an integral part of a modern, multi-modal anatomy curriculum.  相似文献

Three-dimensional (3D) digital anatomical models show potential to demonstrate complex anatomical relationships; however, the literature is inconsistent as to whether they are effective in improving the anatomy performance, particularly for students with low spatial visualization ability (Vz). This study investigated the educational effectiveness of a 3D stereoscopic model of the pelvis, and the relationship between learning with 3D models and Vz. It was hypothesized that participants learning with a 3D pelvis model would outperform participants learning with a two-dimensional (2D) visualization or cadaveric specimen on a spatial anatomy test, particularly when comparing those with low Vz. Participants (n = 64) were stratified into three experimental groups, who each attended a learning session with either a 3D stereoscopic model (n = 21), 2D visualization (n = 21), or cadaveric specimen (n = 22) of the pelvis. Medical and pre-medical student participants completed a multiple-choice pre-test and post-test during their respective learning session, and a long-term retention (LTR) test 2 months later. Results showed no difference in anatomy test improvement or LTR performance between the experimental groups. A simple linear regression analysis showed that within the 3D group, participants with high Vz tended to retain more than those with low Vz on the LTR test (R2 = 0.31, P = 0.01). The low Vz participants may be cognitively overloaded by the complex spatial cues from the 3D stereoscopic model. Results of this study should inform resource selection and curriculum design for health professional students, with attention to the impact of Vz on learning.  相似文献

The novelty of three-dimensional visualization technology (3DVT), such as virtual reality (VR), has captured the interest of many educational institutions. This study’s objectives were to (1) assess how VR and physical models impact anatomy learning, (2) determine the effect of visuospatial ability on anatomy learning from VR and physical models, and (3) evaluate the impact of a VR familiarization phase on learning. This within-subjects, crossover study recruited 78 undergraduate students who studied anatomical structures at both physical and VR models and were tested on their knowledge immediately and 48 hours after learning. There were no significant differences in test scores between the two modalities on both testing days. After grouping participants on visuospatial ability, low visuospatial ability learners performed significantly worse on anatomy knowledge tests compared to their high visuospatial ability counterparts when learning from VR immediately (P = 0.001, d = 1.515) and over the long-term (P = 0.003, d = 1.279). In contrast, both low and high visuospatial ability groups performed similarly well when learning from the physical model and tested immediately after learning (P = 0.067) and over the long-term (P = 0.107). These results differ from current literature which indicates that learners with low visuospatial ability are aided by 3DVT. Familiarizing participants with VR before the learning phase had no impact on learning (P = 0.967). This study demonstrated that VR may be detrimental to low visuospatial ability students, whereas physical models may allow all students, regardless of their visuospatial abilities, to learn similarly well.  相似文献

Given the growing interest in retrieval practice among educators, it is valuable to know when retrieval practice does and does not improve student learning—particularly for educators who have limited classroom time and resources. In this literature review, we developed a narrow operational definition for “classroom research” compared to previous reviews of the literature. We screened nearly 2000 abstracts and systematically coded 50 experiments to establish a clearer picture of benefits from retrieval practice in real world educational settings. Our review yielded 49 effect sizes and a total n?=?5374, the majority of which (57%) revealed medium or large benefits from retrieval practice. We found that retrieval practice improved learning for a variety of education levels, content areas, experimental designs, final test delays, retrieval and final test formats, and timing of retrieval practice and feedback; however, only 6% of experiments were conducted in non-WEIRD countries. Based on our review of the literature, we make eight recommendations for future research and provide educators with a better understanding of the robust benefits of retrieval practice across a range of school and classroom settings.

ABSTRACT

Theoretically, organisational culture, instructor training, and learning space design influence how faculty teach STEM courses. Previous studies have used classroom observation protocols to characterise the range of teaching practices in mostly teacher-centered, traditional STEM classrooms. In this study, we examined the classroom behaviour of 13 STEM faculty teaching biology courses in a reformed undergraduate STEM learning environment. Our findings indicate that instructors teaching in this reformed environment guided student learning (58.4?±?1.9%) almost three times more than they presented information (20.0?±?2.2%). Students worked individually or in groups and talked to the whole class (57.1?±?1.8%) 1.5 times more than they received information (35.5?±?1.9%). We found significant positive correlation between ‘instructor presenting’ and ‘students receiving’ information (r?=?0.743, p?=?1.4?×?10?4) and ‘instructor guiding’ and ‘student working and talking’ in class (r?=?0.605, p?=?7.2?×?10?5), suggesting that instructors can change their own classroom behaviours and expect concurrent change in their students’ behaviours. Finally, sequencing teaching practices in high active-engagement classrooms showed instructors move and guide student group work and lead whole class discussions before lecturing to students, which could lead to deeper learning of conceptual knowledge. We discuss insights from these findings that have implications for acculturating evidence-based teaching practices in STEM departments.  相似文献

Research has shown that the potential benefits of a flipped classroom could be diminished by the way students perceive and prepare information prior to class. This study aims to explore individual characteristics, such as learner motivation, self‐efficacy and epistemology beliefs, that might have an impact on learning outcomes in a flipped classroom. Data were collected using four instruments during a 7‐week flipped classroom conducted from mid‐September 2014 to mid‐November 2014 with a total enrolment of 85 students (10 females and 75 males) in the required course, Applied English for Vocational Education. After controlling for pre‐test and other covariates (eg, gender, grade and experience), an analysis based on structural equation modeling showed a positive and significant (β = 0.12, p < 0.05) indirect effect of instrumentality (promotion) on the change in test scores through averaged quiz scores. Beliefs had a significant positive effect on change in scores between pre‐ and post‐tests (β = 0.20, p < 0.05). Findings revealed that language learners with a high level of motivation in instrumentality (promotion) followed quiz mechanisms closely and thus benefited most from the flipped classroom. Learners with high beliefs exhibited improvement in the post‐tests without doing well in quizzes. The implications for a flipped language learning classroom are discussed, including multiple strategies for regulating learners of different personal traits to preview the online course content before class.  相似文献

Curtin University operates a computer‐managed learning package that gives students the option of undertaking a practice test before the unit assessment. This test is designed predominantly to contribute to student learning and, as such, is considered formative. 417 students took advantage of the optional practice test (PT) and their marks on the unit assessments were compared with those students (N = 197) who opted not to take the practice test (non‐PT). There was a significant improvement in the mean mark of the PT group from the practice test to the first unit test (p < 0.001). The PT group also significantly out performed the non‐PT group. They were significantly better on both unit tests although only the first unit test was preceded by a practice test (p< 0.001). This was despite apparently weaker students opting to sit the practice test. Students who performed the practice test improved their mark on the assessment tests and performed better on these tests than those students who did not do the practice test. Based on these data, practice tests should be offered before all unit assessments despite the implications for departmental resources.  相似文献
