This study involved an investigation of prospective elementary teachers' preconceptions and experiences of diagrams and their ability to draw diagrams in solving math word problems. A questionnaire and two math word problems were administered to prospective elementary teachers who began to taking an introductory mathematics education course. The results from the analysis of their responses to the questionnaire items indicate that prospective elementary teachers appreciate the value of diagrams as tools for problem solving and communication. In addition, prospective elementary teachers have the will not only to teach their future students how to use diagrams but also to encourage them to draw diagrams in solving math word problems. However, the results also indicates that prospective elementary teachers neither use diagrams spontaneously in their math problem solving activities nor have confidence in drawing useful diagrams. Prospective elementary teachers also manifested low scores on the questionnaire items asking whether they were taught how to draw useful diagrams or encouraged by their teachers to use diagrams in their previous learning experiences. The results from the analysis of the diagrams that prospective elementary teachers drew in solving math word problems showed that most of them had difficulty drawing diagrams that represent their reasoning and solving process.

In this paper, we introduce development process and application of a simple and effective model of a statistics laboratory using open source software R, one of leading language and environment for statistical computing and graphics. This model consists of HTML files, including Sage cells, video lectures and enough internet resources. Users do not have to install statistical softwares to run their code. Clicking 'evaluate' button in the web page displays the result that is calculated through cloud-computing environment. Hence, with any type of mobile equipment and internet, learners can freely practice statistical concepts and theorems via various examples with sample R (or Sage) codes which were given, while instructors can easily design and modify it for his/her lectures, only gathering many existing resources and editing HTML file. This will be a resonable model of laboratory for studying statistics. This model with bunch of provided materials will reduce the time and effort needed for R-beginners to be acquainted with and understand R language and also stimulate beginners' interest in statistics. We introduce this interactive statistical laboratory as an useful model for beginners to learn basic statistical concepts and R.

The college students who have relatively weak academic background feel more difficult in learning programming language grammars and programming skills in introductory course. At the end of semester, most of students had the negative attitude to programming and only a few students could write the programs for the given problems because they spent most of time to learn grammars instead of learning problem solving skills and logics. In this study, we propose to use Scratch in introductory programming course to help students to understand grammars and problem solving skills. It's necessary to educate first-time programmers how to solve the problems before they learn grammars of the programming language in their first programming language course. This paper shows that Scratch allows students not only to learn problem solving skills in programming but also to motivate students themselves in the class.

This study was conducted to discover the meaning and the essential structure of the experiences of nursing students' introductory clinical practice. The participants were eight nursing students who had carried out the introductory clinical practice at a hospital. The data was collected from July 15 2019 to July 31, 2019 through focus group discussions and in-depth individual interviews using non-structured questionnaires. The data was analyzed by Colaizzi's phenomenological analysis methodology. The introductory clinical practice experienced by nursing students was categorized as followed: 'Feel worried and concern about expectations at the same time', 'Hospital experience as reality', 'Becoming accustomed to complexed emotion's, 'The first step of becoming a nurse', and 'Preparation for the future'. The five categories were expanded in the same context according to time. The essential structure of the clinical introductory practice experiences of the nursing students revealed by the study is that they begin to practice feeling worried and concerned about expectations, and concern about experience and adaption to various situations, emotions and preparation for the future. Based on the results obtained from this study, it is necessary to develop a realistic and effective education program before starting clinical practice.

In this research, we investigated the support system and professional development in teaching practices of beginning science teachers through instructional consulting. Using open-ended interviews with the participating teachers and group discussions taking place on a regular basis to analyze and compare classes of six beginning teachers, we analyzed beginning teachers' professional development efforts centering around their teaching practices. The group discussion consisted of 6 beginning teachers and another 6 experienced teachers, they discussed and cross-analyzed beginning teachers' 9th lessons on middle school science unit, 'Work and Energy.' The characteristics of beginning science teachers' professional development drawn from this research are: (1) beginning teachers' teaching practices they were taught, (2) lack of reflection on their teaching practices, (3) no guidance for beginning teachers regarding ways to teach, (4) lack of communication between teachers about teaching science, and (5) lack of time for instructional preparation due to other heavy workload. Suggestions for ways to improve and support beginning teachers' professional development are discussed with experienced teachers. Required conditions for an effective induction program are also discussed.
