  • This research is a study on student's understanding fundamental concepts of mathematical curriculum, especially in geometry domain. The goal of researching is to analyze student's concepts about that domain and get the mathematical teaching methods. We developed various questions of descriptive assessment. Then we set up the term, procedure of research for the understanding student's knowledge of geometric figures. And we analyze the student's understanding extent through investigating questions of descriptive assessment. In this research, we concluded that most of students are having difficulty with defining the fundamental concepts of mathematics, especially in geometry. Almost all the students defined the fundamental conceptions of mathematics obscurely and sometimes even missed indispensable properties. And they can't distinguish between concept definition and concept image. Prior to this study, we couldn't identify this problem. Here are some suggestions. First, take time to reflect on your previous mathematics method. And then compile some well-selected questions of descriptive assessment that tell us more about student's understanding in geometric concepts.

  • The purpose of this research was to investigate the descriptive evaluation method that focuses on the problem solving process of the student. The goal was to evaluate the students' understanding of the subject rather than the students' ability to find the final answer. The descriptive evaluation is being suggested as a way of examining the thought process of the student by performing a structured analysis of the problem solving process. Today, there are not enough descriptive evaluation resources available for teachers to effectively carry out this alternative assessment method in the elementary school mathematics curriculum. This research is a case study on the development of resources for descriptive evaluation in grade 4 mathematics. We designed the development process for descriptive evaluation and its rubric for all 8 units of the 4-Na level of mathematics in the elementary school curriculum. Three descriptive problems were developed for each of the 8 units for a total of 24 problems. The rubric consisted of three areas of assessment, 1) understanding of the problem, 2) problem solving, and 3) mathematical communication. The problems were first pilot tested in two 4th grade classes. Modified problems were then tested in a different 4th grade classroom. The study showed that the three defined areas of evaluation framework (problem understanding, problem solving and mathematical communication) were measurable and analyzable using the developed grading rubric. We then conclude that he descriptive evaluation could be used as an effective tool for improving teacher performance in elementary school mathematics.

  • Purpose - In recent years, many companies include franchises have acquire customers by making an online stores and they are carrying out permission marketing activities with e-mail and SMS. Permission marketing requires voluntary customer approval for receiving commercial messages such as cross-selling and upselling. Therefore, it is necessary for the business to induce the customer's acceptance. The purpose of this study is to examine which type of different messages can affect higher in consumer persuasion. Thus, we investigated the impact of descriptive norm message on intention of reception in an online store context, and its interaction with chronic regulatory focus. Research design, data, and methodology - This study hypothesized that the descriptive norm message would affect positive influences to consumers' intension of reception. Specially, this study inquired into whether the interaction effect between descriptive norm and regulatory focus. To verify the hypothesis, we conducted 2 × 2 between-subject factorial design with message type (general message and descriptive norm message) and regulatory focus(promotion focus and prevention focus) as independent variables. Participants of the experiment were assigned to one of 2 kind experimental situations randomly according to characteristics of message type. A total of 131 participants (descriptive norm message: 65, general message: 66) responded for this study. The data were analyzed using frequency analysis, exploratory factor analysis, and two-way ANOVA. Result - The results of the study are as follows. First, we found main effects of the descriptive norm message. The intention of reception were significantly higher in the descriptive norm message rather than general message as in previous researches. Second, interaction effect between the descriptive norm message and regulatory focus was significant. The prevention focus (vs. promotion focus) were hight in a positive behavior intention when the descriptive norm message was given. Conclusions - This study verifies the main effect and interaction effect of descriptive norm message and regulatory focus on the consumers' intention of reception in permission marketing, and persuasive message in the online store context. The results of this study will provide various advantages to companies that want to establish long lasting relationship with customers by carrying out permission marketing in the future.

  • The objective of this study was to investigate taste profiles and the correlation of Doenjang soup solution prepared with three different temperatures (5, 25, $45^{\circ}C$) and using an electronic nose (e-nose), electronic tongue (e-tongue), and descriptive analyses by trained panelists. A total of 17sensory attributes were generated from the descriptive analyses for the Doenjang soup solution. There were significant difference among the samples in the cooked soybean flavor, the cooked soybean odor, the soy sauce odor, the sweet odor, the sweet taste, and the sweet aftertaste attributes. The intensities of these sensory attributes tended to increase as the serving temperature of the Doenjang soup solution increased. There were seven volatile compounds detected by the electronic nose: ethanol, propanal, 2-methylpropanal, ethyl acetate, 3-methylbutanal, and beta-pinene. The intensities of the volatile compounds increased as the temperature of the Doenjang soup solution increased. On the other hand, the intensities of the basic tastes by the e-tongue decreased as the temperature of the Doenjang soup solution increased. In conclusion, the e-nose, e-tongue, and descriptive analysis results showed different correlations depending on the temperature of the Doenjang soup solutions.

  • Sujeonggwa is a popular Korean traditional beverage. However, consumers only prepare it at home on special occasions due to the time and effort required. Developing a convenient form of Sujeonggwa may promote its consumption. The objectives of this study were to 1) develop Sujeonggwa in a tea bag using different sweeteners and 2) describe the characteristics of Sujeonggwa's flavor in tea bag samples and 3) determine how well consumers accept the tea bag samples. A total of four types of Sujeonggwa in a tea bag were developed: two samples with varying amount of sugar, another sample using sugar and stevia and the last sample using sugar and short chain fructo-oligosaccharide as a sweetener. A commercial ginger tea and cinnamon tea were used as control products. Descriptive analysis was conducted on the same six samples and a descriptive panel identified its attributes. A total of 61 consumers evaluated acceptability using a nine-point hedonic scale and how they felt about intensities of the samples using a just-about-right scale. The results indicated that consumers liked Sujeonggwa samples in a tea bag more than commercial ginger tea and cinnamon tea.

  • The purpose of this research was to make fair assessment methods which took into account characteristics of mathematically underachievers. The researchers devised an descriptive tests and interviews and applied them to the mathematics underachievers who could not reveal their achievements in the traditional assessment and then analyzed their cognitive and affective characteristics in the alternative assessments. After selecting three students by the normal assessment made of simple subjective and multiple choice questions, the cognitive and affective characteristics found in the general assessment were reflected to the descriptive tests and interviews. The descriptive tests and interviews are comprised of descriptive narrations and informal interview questions. After the assessment, the teacher and students gave feedbacks one another. All the assessment activities were recorded by a camcorder to analyze cognitive and affective characteristics of the children. Throughout the research, the following conclusions were made. The mathematics underachievers showed the characteristics which didn't appeared in the normal assessment. They showed normal abilities of problem solving and communication In the cognitive area. Also they brought in positive result in most parts in the affective area. However, the student B displayed considerable ability of mathematical thinking that is over the average level of mathematical underachievers. This implies that we can definite the mathematical underachievers differently when we use the detailed and relief assessment method instead of the traditional assessment. On the other hand, one student tended to depend on the teacher and another student overheard what the others talk during the study. This defect should be complemented by the further studies about assessment method for the mathematical underachievers. Also appropriate assessment methods should be made for applying to the various mathematical underachievers. Many studies have been concentrated on the learning for mathematical underachievers but there is little concern about the assessment for the mathematical underachievers. However it is the fundamental way to reduce the number of mathematics underachievers that we construct consistent learning methods and assessments for the mathematical underachievers.
