  • This study investigated the influences of situational interest, attention, and cognitive effort on drawing as a method to assist students to connect and integrate multiple external representations provided in learning chemical concepts. Seventh graders (N=178) at two coed middle schools were taught about the "Boyle's Law" and the "Charles's Law" for two class hours through drawing. They observed macroscopic phenomena through demonstrations. After these observations, they drew their mental model from the external verbal representation, and then compared their drawings with external visual representation. The tests assessing situational interest, attention, cognitive effort, and conceptual understanding were administered as post-tests. Correlation and path analyses supported a causal model which situational interest had a positive direct effect on attention to the drawing. Attention led to conceptual understanding directly as well as through cognitive effort. These results suggest that situational interest may be induced by drawing first of all, and attention and cognitive effort may be direct causes of conceptual understanding in drawing. Educational implications are discussed.

  • Various kinds of cognitive aspects must be inclusively considered for understanding to transitivity. Basically, transitivity is not a notion of pure lexical items, pure syntactic dimensions and only semantic interpretation. That is, transitivity is affected by the extralinguistic phenomena which contain speakers psychological and cognitive interpretations. It is based on human cognitive abilities to interpret the exact meaning of language expressions. To sum up, transitivity has a relation with the observer's (speaker's) cognitive interpretation within the entire contexts.

  • This study was carried out to identify the cognitive obstacles while using addition and subtraction with fractions, and to analyze the sources of cognitive obstacles. For this purpose, the following research questions were established : 1. What errors do elementary students make while performing the operations with fractions, and what cognitive obstacles do they have? 2. What sources cause the cognitive obstacles to occur? The results obtained in this study were as follows : First, the student's cognitive obstacles were classified as those operating with same denominators, different denominators, and both. Some common cognitive obstacles that occurred when operating with same denominators and with different denominators were: the students would use division instead of addition and subtraction to solve their problems, when adding fractions, the students would make a natural number as their answer, the students incorporated different solving methods when working with improper fractions, as well as, making errors when reducing fractions. Cognitive obstacles in operating with same denominators were: adding the natural number to the numerator, subtracting the small number from the big number without carrying over, and making errors when doing so. Cognitive obstacles while operating with different denominators were their understanding of how to work with the denominators and numerators, and they made errors when reducing fractions to common denominators. Second, the factors that affected these cognitive obstacles were classified as epistemological factors, psychological factors, and didactical factors. The epistemological factors that affected the cognitive obstacles when using addition and subtraction with fractions were focused on hasty generalizations, intuition, linguistic representation, portions. The psychological factors that affected the cognitive obstacles were focused on instrumental understanding, notion image, obsession with operation of natural numbers, and constraint satisfaction.

  • The current study examines whether the dementia experience and social support is associated with dementia attitude and whether health literacy moderates the relationship between these variables. We used data from the 2016 Dementia Literacy Survey collected by K University. We conducted our analysis with 522 community-dwelling older Koreans aged 60 to 79. Findings of the multivariate regression analyses showed belows. First, dementia experience and dementia attitude were related in cognitive and behavioral aspects. Second, social support was also related negatively with dementia attitude in cognitive part. However, social support was also related positively with dementia attitude in behavior part. Third, health literacy was positively related with dementia attitude in cognitive part. However, health literacy was negatively related with dementia attitude in behavior part. Lastly, health literacy had significant moderating effects with social support and dementia attitude in cognitive part. Our findings suggest that health literacy plays an important role in fostering a positive dementia attitude.

  • Meanwhile, the meaning has been emphasized in mathematics. But the meaning of meaning had not been clearly defined and the meaning classification had not been reported. In this respect, the meaning was classified as expressive and cognitive. Furthermore, it was reclassified as mathematical situation and real situation. Based on this classification, we investigated how student recognizes the meaning when solving mathematical modeling problem. As a result, we found that the understanding of cognitive meaning in real situation is more difficult than that of the other meaning. And we knew that understanding the meaning in solving of equation, has more difficulty than in expression of equation. Thus, to help students understanding the meaning in the whole process of mathematical modeling, we have to connect real situation with mathematical situation. And this teaching method through unit and measurement, will be an alternative method for connecting real situation and mathematical situation.

  • The purpose of the study was to reveal the effects of visual organizer types and cognitive styles in electronic text understanding. 126 graduate students were divided into a field-dependent group and a field-independent group, and then assigned to two different types of web- based instruction programs which included visual organizers of 'reduction' type and 'abstraction' type. Regarding the comprehension of contents, there were no significant effects of visual organizer types and cognitive styles. However, it was revealed that there were significant interaction effects between visual organizer types and cognitive styles on the awareness of structure in electronic texts. That is to say, while Type 2 ('abstraction' type) was more effective to field-dependent learners, Type 1 ('reduction' type) was more effective to field-independent learners in awareness of structure in electronic texts.

  • It has been known that the tool characteristics embedded in physical tools and virtual tools act with different underlying mechanisms in a user's knowledge acquisition and conceptual understanding. This overview study examines the learning process through the use of physical and virtual tools from the perspective of conceptual frameworks, affordability that tools present, and the depth of cognitive engagement that occurs in the process of learning concepts through various learning activities. Based on the conceptual frameworks, the results of previous comparative studies were reinterpreted. It was found that what mattered for learning is the amount of new information that a tool provides and the different level of cognitive engagement that students use through various learning activities. Finally, the implications to be considered when teachers use physical and virtual tools to help students better understand various concepts are discussed.

  • 원활한 의사소통을 위해서는 문장들을 연결하여 흐름을 조직하고 말로 산출하고 전체적인 의미를 파악할 수 있어야 한다. 이야기는 이러한 문장들이 연결되어있는 것으로, 종속적이거나 나열적인 이야기 특성은 의사소통장애인의 이야기 이해와 산출의 수행에 영향을 미칠 수 있다. 본 연구에서는 이야기 특성에 따른 유창성 실어증환자의 이야기 이해 및 산출의 능력을 알아보고, 이해과제 수행이 산출과제에 미치는 영향을 분석해보았다. 이야기 종류로는 시간적 나열 이야기와 인과적 관계 이야기, 유머가 있는 이야기를 사용하였으며, 사실적 정보, 텍스트 추론, 빠진 정보추론 등 세 가지의 이해과제를 통하여 이해 능력을 측정하였다. 산출능력은 이해과제 전과 후에 CIU 비율로 질적인 측면을 측정하고, 분당어절 수를 이용하여 양적인 측면을 분석하였다. 그 결과 이해측면은 세 가지 이야기 모두 사실적 정보에 대한 이해 능력이 상대적으로 좋았으며, 오류의 형태는 추론오류가 가장 많이 나타났다. 산출에서는 인과적 관계이야기에서의 CIU 비율이 가장 높았고, 이해과제 전, 후의 차이를 비교한 결과, CIU 비율은 변화하지 않았으나, 분당 어절수에서는 증가하고 있음을 보여주었다. 이야기의 종류에 따라서 유창성 실어증화자의 산출과제의 수행수준은 다르게 나타났다. 그리고 이해과제의 수행이 산출과제에서 양적인 증가는 가져왔으나 질적인 수준에는 아무런 영향을 미치지 않았다.
