In an experiment, secondary students from Australia and Malaysia (n = 130) were randomly assigned to one of three approaches (equation, unitary, unitary-pictorial) to learn how to solve challenging percentage-change problems. In line with the differential types of cognitive load associated with the three approaches, the unitary-approach group outperformed both the unitary group and the equation group across Australia and Malaysia. In support of cross-cultural findings, the Malaysian students outperformed the Australian students for the equation approach but not the unitary approach nor the unitary-pictorial approach. The Australian students, in contrast, learned better with the unitary-pictorial approach. This study, overall, reveals the “gap” between the Asian and Western countries in the use of problem-solving approaches across different cultural settings.  相似文献

Within the cognitive load theory framework, we designed and compared three alternative instructional solution formats that can be derived from a common static hierarchical network representation depicting problem structure. The interactive-solution format permitted students to search in self-controlled manner for solution steps, static-solution format displayed all solutions steps, and no-solution format did not have solution steps. When we matched instructional time across the formats, in relation to the complex molarity problems rather than the dilution problems, differential transfer performance existed between the static-solution or no-solution formats and the interactive-solution format, but not between the static-solution format and no-solution format. The manner in which learners interact with the static-solution and no-solution formats depends on their level of expertise in the chemistry domain. With considerable learner expertise, provision of solution steps may be redundant incurring extraneous cognitive load. Absence of the solution steps may not have left sufficient cognitive capacity for germane cognitive load as some beginning learners lacked the prior knowledge to deduce the solution steps. Searching for solution steps presumably incurred extraneous cognitive load which interfered with learning and hence, in the interactive-solution format, it outweighed the benefit of engaging in self-regulated interaction with the content. Hence, cognitive load theory is a promising tool to predict the mental load associated with learning from the three alternative computer-based instructional formats.  相似文献

Individual differences in student learning influence academic performance, and two aspects influencing the learning process are the particular learning approach the students use and procrastination behaviour. We examined the relationships between learning approaches, procrastination and academic achievement (measured 1 year later as the grade point average (GPA)) amongst 428 first-year university students. Deep and strategic learning approaches positively predicted GPA, and a mediation analysis showed that the strategic learning approach also partly mediated the effect between deep learning approach and GPA. Less procrastination was associated with a strategic learning approach, but procrastination tendencies did not predict GPA. Recommendations are made for educating new students in cognitive and meta-cognitive strategies, helping reduce their procrastination and facilitating the use of deep and strategic learning approaches.  相似文献

A methodology for studying change during instruction in content-specific cognitive processes is presented. The methodology borrows both from the cognitive mediational approach in instructional effectiveness research and the instructional approach in cognitive psychology research. It is argued that learning from instruction must be understood in terms of the way in which instruction changes the cognitive processes used to solve tasks. The methodology is illustrated by summarizing a project on instructing middle-school students in semantic processes for solving decimal-fraction problems. The benefits of the methodology, such as tracing the effects of instruction on performance change, are discussed.  相似文献

The scope and complexity of the Australian taxation system (as with other tax regimes) is daunting for many accounting students. This paper documents the implementation of new practices that were initiated in an effort to address some of the challenges faced by undergraduate students studying taxation. Based on the principles of cognitive load theory, summaries of the lecture material became the focus of tutorials. These summaries provided the impetus for teaching staff to experiment with illustrations as a strategic means of delivery. Drawing diagrams and presenting them in the form of pictorial mnemonics proved to be effective tools in helping students understand and synthesize basic taxation concepts, thereby promoting effective deep learning. Both formal and informal feedback was overwhelmingly positive and affirming of this innovative approach to the subject. A selection of the pictorial mnemonics we designed is provided.  相似文献

The interaction between approaches to teaching and students’ learning has been the focus of research for more than 20 years. Previous studies concerning approaches to teaching in higher education have identified two broad categories: content- and learning-focused approaches. Some studies indicate that teachers do not always adopt a consonant teaching- or learning-focused approach, but might employ elements of both, which results in a dissonant approach. Research on how dissonant approaches to teaching and students’ quality of learning are related is scant. This study explored relationships between how teachers’ approaches to teaching and undergraduate students’ self-reported approaches to learning and learning outcomes. The data for this study consisted of 33 semi-structured interviews with students from three courses. Interviews were analysed with qualitative content analysis. The results demonstrated that, when the teacher used a consonant learning-focused approach to teaching, students’ learning outcomes and approaches to learning were of a slightly higher quality than when the teacher employed a dissonant approach to teaching. However, a dissonant approach to teaching did not always result in a lower quality of approaches to learning and learning outcomes.  相似文献

ABSTRACT

In recent decades, a constructivist view of learning has triggered a change in teaching-learning environments (TLEs). Teacher-centred TLEs have been replaced by student-centred ones where the teachers’ approaches to teaching are more learning- than content-focused. Previous research exploring the relationship between student-centred TLEs and the quality of learning has shown contradictory results. Previous studies also indicate that various elements of TLEs may influence students’ learning. This study explored course-level types of elements, enhancing or hindering, related to TLEs, which the course students described. The TLEs of the courses varied because the teachers adopted different types of approaches to teaching. The data for this study were collected through semi-structured interviews with undergraduate students (N = 33) from three compulsory courses. The interviews were designed so that students could describe their perceptions of the course as well as their learning experiences and processes. The data were analysed using qualitative content analysis. The results revealed that when the teacher employed a consonant learning-focused approach to teaching, the students perceived almost all elements of the TLE as enhancing. When the teacher’s approach to teaching was identified as dissonant, the students perceived several elements of the TLE as hindering. This study revealed that inclusion of student-activating teaching-learning activities is important when designing TLEs, but that it is also crucial to design elements which guide and structure students’ learning.

Based on the cognitive-affective theory, the present study designed a science inquiry learning model, predict-observe-explain (POE), and implemented it in an app called “WhyWhy” to examine the effectiveness of students’ science inquiry learning practice. To understand how POE can affect the cognitive-affective learning process, as well as the learning progress, a pretest and a posttest were given to 152 grade 5 elementary school students. The students practiced WhyWhy during six sessions over 6 weeks, and data related to interest in learning science (ILS), cognitive anxiety (CA), and extraneous cognitive load (ECL) were collected and analyzed through confirmatory factor analysis with structure equation modeling. The results showed that students with high ILS have low CA and ECL. In addition, the results also indicated that students with a high level of self-confidence enhancement showed significant improvement in the posttest. The implications of this study suggest that by using technology-enhanced science learning, the POE model is a practical approach to motivate students to learn.  相似文献

ABSTRACT

In this study, a linked data-based annotation approach is proposed. A learning system has been developed based on the approach by providing an annotating function, a linked data enrichment function, a sharing function and faceted search function. To evaluate the effectiveness of this innovative approach, an experiment was carried out in which two classes of students participated. The first class served as the experimental group, in which the students learned with the proposed approach, and the second class served as the control group, in which the students learned with the conventional annotation approach. The experiment results show that the experimental group significantly outperformed the control group. Moreover, the cognitive load of the students in the experimental group was significantly lower than the ones in the control group. This implies that the linked data-based annotation approach not only reduced the students’ cognitive load, but also improved their learning achievement.  相似文献

ABSTRACT

Rubrics can guide teachers to provide effective feedback and students’ peer- and self-assessment. This paper examines the effect of rubric use in flipped learning activities on students’ learning achievement, metacognitive awareness, and cognitive load through a quasi-experiment. A total of 83 university students were randomly assigned to an experimental group or a control group. The students in the experimental group were given rubrics in performing pre-class learning activities on the cloud platform, while those in the control group used rubrics in post-class assessment and modification of their finished works. The results show that rubric use can assist flipped learning by improving students’ learning achievement and metacognitive awareness, while reducing their cognitive load. Using rubrics before in-class work can yield stronger benefits in raising metacognitive awareness and lessening cognitive load. Moreover, the study reveals that students tend to hold a generally favorable attitude toward rubric use. These findings imply that appropriate use of rubrics in flipped learning has the potential to create a more efficient and learner-friendly condition to enhance self-regulated learning.  相似文献

Reading has been regarded as a medium for learning science, revealing the importance of enhancing learners’ reading competence in science education. The critical features of science texts are their multiple representations, such as text and visual elements, which assist the representation of science concepts. A multimedia learning environment can present relevant materials in various formats and help students to process the materials in meaningful ways, for example, by integrating learning materials with relevant prior concepts, and organizing them into a consistent and coherent cognitive structure. However, some issues with multimedia instructional design have been proposed, such as students’ cognitive load and learning motivations. In this study, an augmented reality-based science learning system was developed based on the contiguity principle of multimedia learning in order to promote students’ science learning. Moreover, an experiment was conducted on a natural science course in an elementary school to assess the effectiveness of the implemented system on students’ learning. The experimental results display that the students learning with this approach found made significant gains in their learning achievements and motivations compared to those learning science with conventional multimedia science learning; moreover, their perceptions of extraneous cognitive load were significantly reduced during the learning activity.  相似文献

Computer programming is a subject that requires problem-solving strategies and involves a great number of programming logic activities which pose challenges for learners. Therefore, providing learning support and guidance is important. Collaborative learning is widely believed to be an effective teaching approach; it can enhance learners’ social interaction and offer a learning environment which provides rich learning experiences. However, the social interaction in collaborative learning does not occur automatically. Without proper guidance strategies or supporting tools for collaborative learning, the learning effects can be disappointing. To solve such a problem, a problem posing-based practicing strategy was proposed to support the development of a collaborative learning activity in a computer programming practice course. The students were guided to raise computer programming problems to boost the discussion among team members. The problems raised in each team were then exchanged and solved by another team to examine the coding and to provide feedback. To investigate the effectiveness of the proposed approach, an experiment was conducted in a C# programming course. Two classes of students from a university participated in the experiment. One class with 25 students was randomly assigned as the experimental group, and learned with a collaborative learning activity using the problem posing-based practicing strategy; the other class with 28 students was the control group, which learned with a conventional collaborative learning activity. The results show that the proposed strategy benefited the students in terms of improving their learning achievement, in particular, their programming skills. Moreover, it was found that the students who learned with the proposed approach had higher self-efficacy and lower cognitive load than those who learned with the conventional collaborative learning approach.  相似文献

In this article, I present a longitudinal study comparing problem-solving performance for medical students trained using 2 different approaches to medical education. The first approach is the traditional medical education that involves lectures supplemented by laboratory exercises. The second approach is problem-based learning (PBL). In PBL, students learn basic science in small groups in the context of authentic patient problems. Because an expected outcome of medical education is to move students along the path from naive laypersons to novice physicians, the effects of these approaches should be understood in terms of how they affect the early acquisition of cognitive skill. The results indicate that there are important cognitive benefits of the PBL approach.  相似文献

ABSTRACT

In classroom, scientific contents are increasingly communicated through visual forms of representations. Students’ learning outcomes rely on their ability to read and understand pictorial information. Understanding pictorial information in biology requires cognitive effort and can be challenging to students. Yet evidence-based knowledge about students’ visual reading strategies during the process of understanding pictorial information is pending. Therefore, 42 students at the age of 14–15 were asked to think aloud while trying to understand visual representations of the blood circulatory system and the patellar reflex. A category system was developed differentiating 16 categories of cognitive activities. A Principal Component Analysis revealed two underlying patterns of activities that can be interpreted as visual reading strategies: 1. Inferences predominated by using a problem-solving schema; 2. Inferences predominated by recall of prior content knowledge. Each pattern consists of a specific set of cognitive activities that reflect selection, organisation and integration of pictorial information as well as different levels of expertise. The results give detailed insights into cognitive activities of students who were required to understand the pictorial information of complex organ systems. They provide an evidence-based foundation to derive instructional aids that can promote students pictorial-information-based learning on different levels of expertise.  相似文献

This study investigated a reliable and valid method for measuring cognitive load during learning through comparing various types of cognitive load measurements: electroencephalography (EEG), self-reporting, and learning outcome. A total of 43 college-level students underwent watching a documentary delivered in English or in Korean. EEG was measured during watching, and subjective rating load was reported right after watching. Comprehension was tested for learning achievements. The results demonstrated a positive relationship between difficulty rating by self-report and beta frequency via EEG in the T3 area (Pearson r = .309, p < .05). Difficulty rating and learning performance are correlated negatively and significantly (Pearson r = ?.391, p < .01). The results have theoretical implications supporting cognitive load theory in terms of a negative relationship between the difficulty rating and the learning performance. On the practical side, the study contributes to provide the information of validity of cognitive load measurements.  相似文献

A 2 (learning strategies: diagram vs. summary) × 2 (levels of expertise: low vs. high) experiment was conducted to compare the effectiveness of using diagrams to writing summaries for students given biological information to learn and who possessed different levels of expertise in that topic area. A main effect of learning strategy used on number of idea units encoded (in diagrams or summaries) was found: drawing diagrams was superior to writing summaries. However, no interaction effect between learning strategies and expertise was found. An examination of students’ subjective ratings of cognitive load revealed that those with low expertise reported higher levels of cognitive load when constructing diagrams. These findings suggest that using diagrams is effective for identifying and encoding important information when learning, but that it would be helpful to provide guidance about diagram use particularly to students who are novices in the topic area to reduce cognitive load.  相似文献

In traditional teacher-centered mathematics instruction, students might show low learning motivation owing to the lack of applied contexts. Game-based learning has been recognized as a potential approach to addressing this issue; however, without proper alignment between the gaming and math-applied contexts, the benefits of game-based learning could be limited. Therefore, this study aims to develop a microworld-based educational game, which provides simulated contexts encouraging students to explore, discover, and solve practical problems using the mathematics knowledge gained in the class. A quasi-experimental design was implemented in the learning activity of the “Speedy World” unit in an elementary school mathematics course to examine the effectiveness of the proposed approach. A total of 107 sixth graders participated in the experiment. The experimental results showed that the students who learned with the microworld-based gaming approach had better learning achievement and motivation in the mathematics course than those who learned with the conventional technology-enhanced learning approach. In addition, the students also showed that they highly accepted the microworld-based game for learning mathematics. The findings of this study provide good evidence for the importance and necessity of associating authentic applied contexts with gaming contexts in developing computer educational games for mathematics.  相似文献

For this study the researchers designed learning activities to enhance students’ high level cognitive processes. Students learned new information in a classroom setting and then applied and analyzed their new knowledge in familiar authentic contexts by taking pictures of objects found there, describing them, and sharing their homework with peers. An experiment was carried out in which 58 junior high school students were divided into a control (n = 30) and an experimental (n = 28) group. The control group studied and completed learning activities with traditional textbooks while the experimental group used electronic textbooks and a learning system, Virtual Pen for Tablet PC (VPenTPC), in order to gauge the feasibility of the proposed approach. The post-test results show a significant difference between the control and experimental groups. In our analysis of the various approaches students took to complete the task, we were able to identify thirty cognitive and metacognitive strategies for using mobile technology, from which we selected the ten most frequently used ones. The results show that low ability students make better use of strategies than their high ability peers, resulting in significant learning gains. The results also show that most students perceive VPenTPC positively. Based on these results, we suggest some implications along with conclusions and directions for future research.  相似文献

In this study, a spreadsheet-based visualized Mindtool was developed for improving students’ learning performance when finding relationships between numerical variables by engaging them in reasoning and decision-making activities. To evaluate the effectiveness of the proposed approach, an experiment was conducted on the “phenomena of climate on earth” unit of an elementary school geography course. The experimental results showed that the spreadsheet-based visualized Mindtool significantly benefited the students in terms of improving their learning achievement and promoting their learning attitudes and satisfaction. Moreover, the cognitive load of the students was significantly decreased, indicating the effectiveness of this approach in helping students comprehend, learn content and organize their knowledge. To further investigate the learning behaviors of high-achievement and low-achievement students in using the spreadsheet-based Mindtool, a learning pattern analysis was conducted by coding the students’ behaviors recorded on video.  相似文献
