The purpose of this study is to develop authentic assessment model and example tools of mathematics teaching and learning. By reviewing literature researches, we set up the definition of authentic assessment in mathematics education, checked the criterian of authentic assessment tasks and mathematical activities. We searched various assessment models of mathematics teaching and learning, project assessment proceeding model, and criterian of project assessment, and checked various project tasks of the authentic assessment. And we developed authentic assessment model and example tools of mathematics teaching and learning. The model is applied project tasks in the form of being integrated with class to high school students, with high school mathematics especially. Furthermore, we carried the test of content validity for a validity of developed tasks for experts in studies of mathematics education. The result is that authentic assessment model and example tools of mathematics teaching and learning has an significance in mathematics education and can be used to judge whether students are doing 'real' mathematics or not, keeping the applicability in the form of being integrated with class.

In order to increase corporate competitiveness in the fourth industrial revolution environment, it is most important to secure and nurture talented people with digital capabilities. In particular, because the knowledge and skills required in the IT sector are newly created or added, enhancing expertise through upskilling and reskilling of IT company members is essential. Thus, this study proposed theoretical discussions and practical implications for strengthening the competitiveness of IT company in terms of human resource development by analyzing the mediating effects of subordinates' self-directed learning ability in the relationship between managers' authentic leadership and subordinates' work engagement. The results of this study were as follows: First, authentic leadership of IT company manager had positive effect on subordinates' work engagement. Second, self-directed learning ability of subordinates' had partial mediating effect on the relationship between IT company manager's authentic leadership and subordinates' work engagement.

Many universities are searching for educational methods to cultivate problem-solving ability and cooperative learning ability or already trying to implement them. Problem Based Learning(PBL) and Action Learning(AL) are effective teaching and learning methods to cultivate men of talent qualified for problem-solving and cooperative learning abilities that universities are seeking after. PBL and AL have something in common in that learning is accomplished while learners are solving the authentic problem. But, in spite of this similarity, PBL and AL have differences. However, most literatures and cases on these two models introduce only the outline of commons and differences and do not provide teachers with actual helping aids to select a model appropriate for the actual design or operation of classes. Accordingly, many teachers usually select and utilize a familiar model rather than select a proper model to the nature of a subject and the educational goal. Teaching and learning methods or learning environment should be selected appropriately to the educational goal. This study indicates the characteristics of PBL and AL that are being introduced and utilized as a principal teaching and learning method of college education and then shows how this method can be realized in the university by comparing the cases of classes applied in two methods.

International virtual teamwork offers new opportunities for the professional development of teachers. In this paper, we examine the initial experiences in an ongoing international virtual benchmarking project coordinated by the Finnish Online University of Applied Sciences. What challenges does an international context present for project construction and collaboration? Data from five countries, in the form of participant reflections and researchers' observations, were analysed according to four types of barriers: language, time, technical and mental barriers. Initial data indicates that trust is an essential starting point, as there is neither time nor possibilities to build mutual trust by traditional means. Organisational confidentiality issues, however, can complicate the situation. The project introduces 'collision' as a method of professional development, in which physical and organisational borders are crossed and the skills and competencies needed in global learning environments are acquired.

In this study, we created, implemented, and evaluated the impact of proportional reasoning authentic investigative activities on the mathematical content and pedagogical knowledge and attitudes of pre-service elementary and middle school mathematics teachers. For this purpose, a special teaching model was developed, implemented, and tested as part of the pre-service mathematics teacher training programs conducted in Israeli teacher colleges. The model was developed following pilot studies investigating the change in mathematical and pedagogical knowledge of pre- and in-service mathematics teachers, due to experience in authentic proportional reasoning activities. The conclusion of the study is that application of the model, through which the pre-service teachers gain experience and are exposed to authentic proportional reasoning activities with incorporation of theory (reading and analyzing relevant research reports) and practice, leads to a significant positive change in the pre-service teachers' mathematical content and pedagogical knowledge. In addition, improvement occurred in their attitudes and beliefs towards learning and teaching mathematics in general, and ratio and proportion in particular.

Application (app) ratings are feedback provided voluntarily by users and serve as important evaluation criteria for apps. However, these ratings can often be biased owing to insufficient or missing votes. Additionally, significant differences have been observed between numeric ratings and user reviews. This study aims to predict the numeric ratings of Google apps using machine learning classifiers. It exploits numeric app ratings provided by users as training data and returns authentic mobile app ratings by analyzing user reviews. An ensemble learning model is proposed for this purpose that considers term frequency/inverse document frequency (TF/IDF) features. Three TF/IDF features, including unigrams, bigrams, and trigrams, were used. The dataset was scraped from the Google Play store, extracting data from 14 different app categories. Biased and unbiased user ratings were discriminated using TextBlob analysis to formulate the ground truth, from which the classifier prediction accuracy was then evaluated. The results demonstrate the high potential for machine learning-based classifiers to predict authentic numeric ratings based on actual user reviews.

The purpose of this study is to help teachers and program developers develop comprehensive and authentic assessment models with appropriate ways of using various kinds of assessment tools in college English instruction and assessment. Assessing by traditional discrete tests based on grammar and vocabulary cannot measure the authentic ability for language use in meaningful context in the real world. Currently, the trend in language assessment is changing to performance assessment. Increased use of performance assessments that involve language students in selecting and reflecting on their learning means that language teachers will have a wider range of evidence on which to judge whether students are becoming purposeful and are able to communicate as English users. Also, language programs focused on performance assessment are likely to instil in students authentic skills related to communication in the global world and enable them to evaluate what they learn from their English classes. In this study, the author investigated the theoretical background, the need of change, and several types of performance assessment.

I studied on the relations of constructivism and school library assisted instruction in this paper. Constructivism is the most important goal of the modern schooling. In constructivism they insist that knowledge is constructed by the learner individually and subjectively. So in constructivism they focus their attention on setting authentic environment of learning for each individual learner. Constructivism was developed into the learner-centered instruction in schooling nowadays. In constructivism the following instructions are very important for achievement its' goal ; problem based learning, project based learning, discussion based learning etc. These instructions are supported commonly by resource based learning. Educational resources are managed in school library totally. School library assisted instruction is the most effective one for resource based learning. And information literacy instruction by teacher librarian relates closely meta cognitive learning of reflections in constructivism. School library assisted instruction is the essential element for the practice of constructivism in schooling.
