The purpose of this study was to examine the extent to which three teachers’ professional experience and existing orientations toward teaching and learning mathematics and science influenced their implementation of a project-based curriculum (i.e. project-based learning (PBL)). Data sources included interviews, videotapes of classroom activity, and a teaching philosophy questionnaire. Data analysis was conducted using an iterative coding technique. We found coherency between the teachers’ perceived orientations and their emergent ideas about PBL, their sense of PBL as being compatible with their goals, and the specific challenges with which they struggled. All the teachers wanted their students to be successful; however, different definitions of success led to quite different approaches toward teaching, and for the most part, these differences appeared to have occurred because of existing orientations the teachers held for teaching their discipline. Implications for professional development taking into account teachers’ orientations and thus their professional experience are discussed, as well as disciplinary challenges to using PBL.  相似文献   

Goethe’s Conception of “Experiment as Mediator” and Implications for Practical Work in School Science     

Wonyong Park  Jinwoong Song 《Science & Education》2018,27(1-2):39-61

There has been growing criticism over the aims, methods, and contents of practical work in school science, particularly concerning their tendency to oversimplify the scientific practice with focus on the hypothesis-testing function of experiments. In this article, we offer a reading of Johann Wolfgang von Goethe’s scientific writings—particularly his works on color as an exquisite articulation of his ideas about experimentation—through the lens of practical school science. While avoiding the hasty conclusions made from isolated experiments and observations, Goethe sought in his experiments the interconnection among diverse natural phenomena and rejected the dualistic epistemology about the relation of humans and nature. Based on a close examination of his color theory and its underlying epistemology, we suggest three potential contributions that Goethe’s conception of scientific experimentation can make to practical work in school science.  相似文献   

Skills for Independence for Children with Cerebral Palsy: a comparative longitudinal study     

Jane Jung‐Ae Hur 《International Journal of Disability, Development & Education》1997,44(3):263-274

Thirty‐six children with cerebral palsy, aged 3.5 to 4.5 years were compared on their skills for independence. Of the 36 boys and girls, 19 children were enrolled in a Conductive Education Program in Birmingham and 17 were enrolled in British special education programs in the Greater Manchester area. Skills for independence were measured with the Vineland Adaptive Behavior Scales via teachers’ responses, once a year on three occasions. Parents were interviewed using the Developmental Profile 2, once a year on three occasions. The results of two‐way ANOVA with one repeated measure on both teachers’ and parents’ responses indicate that there was no significant difference between the two groups in their skills for independence. However, both groups performed significantly better as they were getting older. Despite the strong emphasis on independence in Conductive Education, the children's level of independence was no different from their counterparts. Thus, the claim for the effectiveness of Conductive Education is not supported by the study.  相似文献   

Multiple Dimensions of Instructional Effectiveness in Reading: A Review of Classroom Observation Studies and Implications for Special Education Classrooms     

Yujeong Park  Mary T. Brownell  Elizabeth F. Bettini  Amber E. Benedict 《Exceptionality》2019,27(1):1-17

The purpose of this study was to review and analyze effective classroom reading practices for early graders, using information gathered from the existing content-general and content-specific observation protocols measuring teachers’ classroom reading practices. Dimensions and constructs from 28 observation studies were synthesized to identify classroom instructional practices that have positive impacts on student achievement. Findings revealed that (a) instructional support, emotional support, and classroom management have positive impacts on student achievement, (b) the degree to which instructional practices are effective depends on students’ particular learning needs, and (c) students’ entering skills and primary language are associated with instructional effectiveness in reading. Challenges and implications for future research on effective instructional strategies for special education and the development of an observational protocol for special education teacher effectiveness are discussed.  相似文献   

Developing self-awareness using mindfulness meditation with preservice teachers: reflections on practice     

Mi-Hwa Park  Jeanetta G. Riley  Jessica M. Branch 《Journal of Early Childhood Teacher Education》2020,41(2):183-196

ABSTRACT

Mindfulness offers a pathway for preservice teachers to develop self-awareness, which is an essential part of personal and professional growth. However, supporting teacher self-awareness is rarely given much attention in teacher education programs. The authors studied the use of mindfulness meditation in an early childhood college course with early childhood preservice teachers. This article reports the main findings that emerged from the students’ journals regarding the mindfulness meditation. Reflecting on the findings, this article suggests that educators need to provide meaningful learning experiences and activities, which could help their students develop the personal qualities necessary to teach with high self-confidence.  相似文献   

Antimelanogenic effects of <Emphasis Type="Italic">Inula britannica</Emphasis> flower petal extract fermented by <Emphasis Type="Italic">Lactobacillus plantarum</Emphasis> KCCM 11613P     

Eun-hye Park  Won-young Bae  Jae-yeon Kim  Kee-tae Kim  Hyun-dong Paik 《Journal of Zhejiang University. Science. B》2017,18(9):816-824

The inhibitory effects of Lactobacillus plantarum-fermented and non-fermented Inula britannica extracts on the tyrosinase activity were comparatively investigated to examine whether and how they improve the whitening activity, and the contents of total flavonoids and polyphenolics as bioactive compounds were determined. The skin whitening activity using in vitro or ex vivo tyrosinase and L-3,4-dihydroxyphenylalanine (L-DOPA) staining was examined. The total flavonoid content (TFC) was increased by 13.4% after 72 h-fermentation. The viabilities of the B16F10 cells treated with the fermented and non-fermented control extracts were 100.26% and 92.15% at 500 μg/ml, respectively. In addition, the inhibition of tyrosinase activity was increased by the fermented samples from 29.33% to 41.74% following fermentation for up to 72 h. The tyrosinase activity of the untreated control group was increased to 145.69% in B16F10 cells. The results showed that I. britannica fermented by L. plantarum dose-dependently inhibited tyrosinase activity, which was stimulated by α-melanocyte stimulating hormone. These results suggest that lactic fermented I. britannica extracts can be used as effective skin-whitening materials.  相似文献   

A quantitative analysis of moral exemplars presented in moral education textbooks in Korea and Japan     

Hyemin Han  Sung Choon Park  Jongsung Kim  Changwoo Jeong  Yutaka Kunii  Sora Kim 《Asia Pacific Journal of Education》2018,38(1):62-77

This study is a comparative analysis of the characteristics of moral exemplars presented in moral education textbooks in Korea and Japan. The purpose of the study is to examine and compare moral values presented through the lives and stories of moral exemplars in the two countries that have moral education as an independent and separate subject based on the national curriculum. To this end, the study uses analytical criteria such as gender, nationality, social roles, historical backgrounds, and specific moral values in order to investigate characteristics of 307 moral exemplars in Korea’s and Japan’s most used moral education textbooks. The results show significant similarities and differences in moral exemplars between the two nations. In the case of the similarities, both countries emphasize moral autonomy and respect for human life. In the case of the differences, while Korea presents more historic figures as moral exemplars, Japan presents more students and ordinary people as moral exemplars.  相似文献   

Use of place information for improved event tracking     

Yun Jin  Sung Hyon Myaeng  Yuchul Jung 《Information processing & management》2007

The main purpose of topic detection and tracking (TDT) is to detect, group, and organize newspaper articles reporting on the same event. Since an event is a reported occurrence at a specific time and place and the unavoidable consequences, TDT can benefit from an explicit use of time and place information. In this work, we focused on place information, using time information as in the previous research. News articles were analyzed for their characteristics of place information, and a new topic tracking method was proposed to incorporate the analysis results on place information. Experiments show that appropriate use of place information extracted automatically from news articles indeed helps event tracking that identify news articles reporting on the same events.  相似文献   

Scaffolding learning of language structures with visual-syntactic text formatting     

Youngmin Park  Ying Xu  Penelope Collins  George Farkas  Mark Warschauer 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(4):1896-1912

The current study examines the effects of digital scaffolding on the English literacy of fourth- and sixth-grade students. A total of 1085 native English-speaking and language minority students from 25 treatment classes and 20 control classes across three school districts participated in this study for one school year. Treatment students read their English language arts and social studies text in visual-syntactic text format (VSTF) on their laptops and control students read the regular block format of the textbook either on their laptops or in print. Observations and interviews revealed that VSTF reading facilitated instruction processes and student learning in reading activities. The results of California Standard Tests (CST) before and after the treatment revealed that sixth-graders who received syntactic scaffolding outperformed control students on the composite CST score. In particular, reading in VSTF benefited the treatment students in three CST sub-categories: word analysis, written conventions and writing strategies. This study suggests that future research should investigate instructional strategies that support reading and writing development of adolescents, including at-risk students, using syntactic scaffolding.  相似文献
