This study examined the effects of conditions of generation(0, 1, or 2 cognitive operations) and task difficulty in children's recall. Subjects were 40 children in each age group, 8-year-olds and 10-year-olds. Each subject was shown 12 simple or difficult multiplication problems in one of the conditions of generation. After a buffer task, subjects were required to recall correct answers to the problems in random order. The data were analyzed by ANOVA and simple main effect analyses. Results showed that generation effect(GE) occurred among children younger than 12, and GE improved with age. Learning from cognitive operations was more effective than learning through simple repetition. Easier tasks led to greater GE, a phenomenon explained by procedures used in this study.

Mental workload has a improtant place in modern work environment such as human-computer interaction. Designing man-machine system requires knowledge and evaluation of the human cognitive process which controls information flow during our works. Many studies estimate reaction time as a index of menatal workload. This paper investigates what reflacts the workload of human information handling when the informations grow its degree. Experiment result introuce the memory time that explain the information-load more sensitive than react time. And react time shows learning effect but memory time does'nt show that effect So it can be concluded that cognitive learning or work schema needs more time to achieve dexterity than motor skill.

In implicit learning tasks, human participants learn grammatical letter strings better than random letter strings. After learning grammatical letter strings, participants were able to judge the grammaticality of new letter strings that they have never seen before. EPAM (Elementary Perceiver and Memorizer) IV, a rote learner without any rule abstraction mechanism, was used to simulate these results. The results showed that EPAM IV with a within-item chunking function was able to learn grammatical letter strings better than random letter strings and discriminate grammatical letter strings from non-grammatical letter strings. The success of EPAM IV in simulating human performance strongly indicated that recognition memory based on chunking plays a critical role in implicit learning.

The purpose of this study is to develop appropriate science teaching models which can be applied effectively to relevant situations. Five science teaching models; cognitive conflict teaching models, generative teaching model, learning cycle teaching model, hypothesis verification teaching model and discovery teaching model, were identified from the existing models. The teaching models were modified and in primary and secondary students using a nonequivalent pretest-posttest control group design. Major findings of this study were as follows: 1. For teaching science concepts, three teaching models were found more effective; cognitive conflict teaching model, generative teaching model and discovery teaching model. 2. For teaching inquiry skills, two teaching models were found more effective; learning cycle teaching model and hypothesis verification teaching model. 3. For teaching scientific attitudes, two teaching models were found more effective; learning cycle teaching models and discovery teaching model. Each teaching model requires specific learning environment. It is strongly suggested that teachers should select a suitable teaching model carefully after evaluating the learning environment including teacher and student variables, learning objectives and curricular materials.

Prior research has reported that student epistemological beliefs might affect their participation in learning and the process of conceptual change. The purposes of this study were to investigate the characteristics of sixth grade students epistemological beliefs about science and the relation between their epistemological beliefs about science and factors related their learning. For this research questions, 245 sixth grade students participated and various test instruments were used in this study. Students answered two types of questionnaires on epistemological beliefs about science and three test instruments on factors related students' learning(achievement in science, science inquiry skills, and cognitive levels). The results of this study were as follows. First, a large number of elementary school students believed that the purpose of science to perform activities like simple experiments. A lot of students believed that scientific knowledge was changeable according to the nature of scientific knowledge and that scientific knowledge could be learnt on their own. Also, many students believed experiment results to be basis on which to form personal scientific conceptions. Second, students who believed in more modern epistemology about science represented higher levels of science learning achievement, science inquiry skills, and cognitive levels. Therefore, when developing science curriculum, science educators need to consider how to develop student modern epistemological beliefs about science.

This study employed a child-centered approach in the examination of patterns of preschooler's learning behaviors. A hierarchical cluster analysis was employed in order to discern a meaningful typology of such behavior. The subjects consisted of 232 children (117 boys, 106 girls) and their mothers from 6 kindergartens and 6 day care centers. The results of this study were as follows. The cluster analysis yielded five types of learning behaviors; the competent type, the average type, the low attention/persistence type, the low motivation -attitude type, and the deficient type. The most consistent level differences among these types appeared to lie in distinctions among the average Attention/Persistence scores. The composition of the cluster types, including both the age and gender of the children, was ascertained. Our results indicated that preschool learning behavior types could be seen to differentially relate to children's self-regulation, cognitive styles, problem behaviors, and the level of maternal involvement. It was revealed that a child's characteristics was more important than maternal involvement and beliefs. As there were more girls and older children in the learning type, this type was seen to be more competent.

This study is to investigate how do elementary students' eye movements appear in cognitive process that they perceive science learning materials depending on motivation system of science learning. For this study we had a random sampling of 301, 6th grade students. And we had selected 32 students through the three tests for the final; motivation system test of science learning, a learning styles test, an Edinburgh inventory for handedness test. We were analysis the cognitive process during learning tasks for the selected student using eye-tracking equipment. The results of the research are as follows: First, when students see a science learning material, we found out that SL-BAS group that has tendency searched various areas than SL-BIS group in learning task. Second, results confirmed through the data of integrational count that students looked alternately texts, images and graphs in the learning material, SL-BIS group were more than SL-BAS group on integrated count, but they had a simple and insignificant eye movement. Especially SL-BAS students showed that integrated eye movement between texts, images and graphs in the learning material, and they explored important areas of the graph compared with SL-BIS group that there was no eye movement in graph. These results may be utilized as a useful resource for designing students' learning.

This study was conducted to test the effect of flipped learning on academic self-efficacy, achievement goal, cognitive engagement of nursing students. This study used a one group pre-post test design. Participants were 91 students who were taking the health and physical assessment in nursing. The flipped learning was provided for 5 times (10 hours). The data of 91 people who agreed to the study and responded to the pre and post questionnaires were analyzed. Data were collected between September 26 and November 25, 2022. Data were analyzed by frequencies, paired t-test using SPSS WIN 24.0. The results showed that self-efficacy of learning(t=-5.445, p<.001), and cognitive engagement(t=-2.120, p=.035) increased significantly. As a result of the study, it was proved that flipped learning is effective for self-efficacy of learning and cognitive engagement. But it is necessary to conduct repeated studies due to limitations in research design, and to explore ways to utilize various teaching-learning strategies to improve the learning ability and clinical performance of nursing students.

This study aims to explore cognitive biases relating the core competences of science and instructional strategy in reducing the level of cognitive biases. The literature review method was used to explore cognitive biases and science education experts discussed the relevance of cognitive biases to science education. Twenty nine cognitive biases were categorized into five groups (limiting rational causal inference, limiting diverse information search, limiting self-regulated learning, limiting self-directed decision making, and category-limited thinking). The cognitive biases in limiting rational causal inference group are teleological thinking, availability heuristic, illusory correlation, and clustering illusion. The cognitive biases in limiting diverse information search group are selective perception, experimenter bias, confirmation bias, mere thought effect, attentional bias, belief bias, pragmatic fallacy, functional fixedness, and framing effect. The cognitive biases in limiting self-regulated learning group are overconfidence bias, better-than-average bias, planning fallacy, fundamental attribution error, Dunning-Kruger effect, hindsight bias, and blind-spot bias. The cognitive biases in limiting self-directed decision-making group are acquiescence effect, bandwagon effect, group-think, appeal to authority bias, and information bias. Lastly, the cognitive biases in category-limited thinking group are psychological essentialism, stereotyping, anthropomorphism, and outgroup homogeneity bias. The instructional strategy to reduce the level of cognitive biases is disused based on the psychological characters of cognitive biases reviewed in this study and related science education methods.
