Set Up

The work of the engineer in design, research, or development very often involves extensive arithmetical computations. For this he uses a slide rule, computing machine, and sometimes logarithms, but first the factors are set up in some convenient form for easy manipulation. In all his work the engineer is concerned with two things: short cuts to save time, and accuracy. Herewith is outlined a method which constitutes somewhat of a short cut and at the same time results in increased accuracy for arithmetical computation. It is a method much used by engineering students and practicing engineers; it is very convenient, and should be made available to high school students.

Set Up

Modern aspects of many subjects (e.g., computer science and some aspects of medical science) are now taught in many high schools, but the plant sciences are often given short shrift. A collaboration was therefore established with a high school biology program in which pilot workshops could be developed to enable advanced students to gain insights into modern plant science techniques. A successful example is the workshop on plant biotechnology presented in this report. This workshop is simple and flexible, taking into account that most high school biology laboratories and classrooms are not set up for sophisticated plant science/biotechnology projects. It is suitable for from 10 to 30 students, depending upon space and facilities available. Students work in pairs or trios, and learn simple disinfestation and transfer techniques for micropropagation and potential subsequent transformation treatments. Students gain insights into: sterile technique and hygiene; plant hormones and their physiological effects; plant cell, tissue and organ culture; the influence of environmental factors on response of cells and tissues cultured in vitro; and an understanding of the phenomenon of organogenesis and resulting plant growth and development. This workshop has been tested on several classes of students and following analysis, several refinements were included in subsequent iterations. Results of the students' experiments have been positive and instructive, with student learning outcomes above expectations. Further details of the workshop techniques and approach will be presented.

Student Meaning

Written fluency and fluency building activities have been shown to promote linguistic choice and student voice development, increased ability to express ideas using complex grammatical structures and greater intrinsic motivation in English language learners. Since the 1970’s, process-oriented writing has been emphasized, yielding an amplified focus on meaning of student content over linguistic form precision. Current research of writing fluency must delve deeper into questions of student ownership of topic and the outcomes for low-risk activities that support fluency practice and encourage confidence building in students. The purpose of this replication study is to further explore previous findings on the effects of topic selection on writing fluency for high school English as foreign language learners. Building off of the work of Bonzo (2008), this study focused on a timed, non-graded writing activity administered to groups of Japanese engineering students in three departments: mechanical, electrical, and global engineering. The six subsequent samples for each participating student were analyzed using online text-analysis for total and unique word counts, providing data used to perform a t-test. Responses to bi-lingual student questionnaires, with prompts on self-perceived written English ability, self-efficacy and strategies for success while writing, provided additional insight into the facets of fluency. The results of these writing sessions offer both confirmation of and contrast to Bonzo’s original work, demonstrate increased student meaning making, and support the use of free writing activities in English language classrooms as a means by which student written fluency may be improved.

AbstractThe purposes of this study were to integrate imagination and STEAM education to construct a special topic course on wearable devices for pets for technology senior high school students studying electronic science; to explore the impacts of the learning process on students’ imagination, STEAM competences and satisfaction with learning effectiveness; and to investigate the integration of imagination into STEAM education. This study adopted the design research method and took 40 students in the third year of a special topic course in electronic science at a technology senior high school as the research subjects. The students were randomly divided into 8 groups, and teaching activities were carried out for 18 weeks. This study used questionnaire and documentary analysis methods to carry out peer evaluation, pretests, posttests and student self-report surveys to collect qualitative and quantitative data for statistical analysis and cross-validation. In this study, a new integration model of imagination and STEAM is proposed. The design research method was employed to plan the iSTEAM course and design special topic activities about real-life issues so that the degree of integration of imagination into the STEAM special topic course and the quality of the students’ work were moderately positively correlated and highly positively correlated, respectively, with students’ application of their learning from various aspects of iSTEAM, which can significantly enhance their imagination, STEAM competences, and satisfaction with their learning effectiveness. The iSTEAM teaching model can help engineering educators develop and evaluate iSTEAM courses and learning activities and provides new contributions to and research directions for STEAM education.

In 2017, the Ministry of Education promulgated the General High School English Curriculum Standards (2017 Edition), which stressed the importance of affective factors in English learning. This study uses a combination of qualitative and quantitative research methods such as student questionnaires and interviews to explore the motivational function of affective factors and its negative influence upon English reading of 80 students with low English reading ability in a high school in Jiujiang. The results of the study show that reading anxiety is common among high school students, the internal motivation for English reading is weak and the external motivation is strong, the self-efficacy of reading is not clear and firm. The study further found that the great academic pressure and high school students’ self-awareness which are subject to external environment, language and other factors cause high school students’ anxiety, the international social environment and examination system have a large impact on high school student’ external motivation. In order to improve the English reading ability of high school students, this research tries to make corresponding suggestions for teachers, students and other aspects from the perspective of affective factors. As for the English teachers, they should set up diversified activities and increase the interest of teaching content in order to promote emotions with knowledge. As for the students, they should clarify their tasks to enhance learning motivation. The school should set up mental health courses and psychological counseling room and provide psychological training for teachers. Then, parents should try to communicate with students and learn to ask for help rather than paying too much attention to students’ performance.
