In her commentary Danielle J. Ford mainly focused on three issues that highlight the promises and challenges for the use of Adapted Primary Literature (APL) in science curricula: the possible contribution of APL to authentic experiences in secondary schools, implementation issues of APL including the support required for the teachers, and the possibilities to extend the use of APL to younger and older students. In this rejoinder, we first offer some general comments on Ford’s commentary. Then we offer more specific comments on two areas of her response, authenticity and the support for teachers.  相似文献   

Learning Using Dynamic and Static Visualizations: Students’ Comprehension, Prior Knowledge and Conceptual Status of a Biotechnological Method   总被引：1，自引：0，他引：1  

Hagit Yarden  Anat Yarden 《Research in Science Education》2010,40(3):375-402

The importance of biotechnology education at the high-school level has been recognized in a number of international curriculum frameworks around the world. One of the most problematic issues in learning biotechnology has been found to be the biotechnological methods involved. Here, we examine the unique contribution of an animation of the polymerase chain reaction (PCR) in promoting conceptual learning of the biotechnological method among 12th-grade biology majors. All of the students learned about the PCR using still images (n = 83) or the animation (n = 90). A significant advantage to the animation treatment was identified following learning. Students’ prior content knowledge was found to be an important factor for students who learned PCR using still images, serving as an obstacle to learning the PCR method in the case of low prior knowledge. Through analysing students’ discourse, using the framework of the conceptual status analysis, we found that students who learned about PCR using still images faced difficulties in understanding some mechanistic aspects of the method. On the other hand, using the animation gave the students an advantage in understanding those aspects.  相似文献   

Validating human and automated scoring of essays against “True” scores     

Yoav Cohen  Effi Levi  Anat Ben-Simon 《教育实用测度》2018,31(3):241-250

ABSTRACT

In the current study, two pools of 250 essays, all written as a response to the same prompt, were rated by two groups of raters (14 or 15 raters per group), thereby providing an approximation to the essay’s true score. An automated essay scoring (AES) system was trained on the datasets and then scored the essays using a cross-validation scheme. By eliminating one, two, or three raters at a time, and by calculating an estimate of the true scores using the remaining raters, an independent criterion against which to judge the validity of the human raters and that of the AES system, as well as the interrater reliability was produced. The results of the study indicated that the automated scores correlate with human scores to the same degree as human raters correlate with each other. However, the findings regarding the validity of the ratings support a claim that the reliability and validity of AES diverge: although the AES scoring is, naturally, more consistent than the human ratings, it is less valid.  相似文献   

Active learners’ characterization in MOOC forums and their generated knowledge     

Anat Cohen  Udi Shimony  Rafi Nachmias  Tal Soffer 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(1):177-198

This study explores and characterizes learners' participation patterns in MOOC forums, as well as the factors that correlate with learners' participation. Educational data mining and learning analytics methods were used to retrieve and analyze the learners' interpersonal interaction data, which had accumulated in the Coursera log files. The content in the forums was categorized based on Henri's criteria and converted into quantitative values that could be compared and visualized. It was found that only 20% of the learners were collaborating in the forums throughout the entire course and were responsible for 50% of the total posts. A portion of them earned the name “Super Active.” The analyses not only demonstrated the volume of activity and its pattern but also revealed the content of the discussions, which helped to highlight the needs and reasons for students' usage of the forums. The content analysis showed intensity in the “Cognitive” and “Discipline” categories. Thus, forum participants benefit from discussions not only socially but disciplinarily and cognitively as well. Furthermore, even though a strong significant correlation was found between the learners’ completion status and their activity in the forums, a group of learners, who did not complete the course, was highly active.  相似文献   

Separating the research question from the laboratory techniques: Advancing high‐school biology teachers' ability to ask research questions     

Eilat Hasson  Anat Yarden 《科学教学研究杂志》2012,49(10):1296-1320

Inquiry is essentially a process in which research questions are asked and an attempt is made to find the answers. However, the formulation of operational research questions of the sort used in authentic scientific inquiry is not a trivial task. Here, we set out to explore the possible influence of separating the research question from the laboratory techniques used to try and answer this question on teachers' understanding of laboratory techniques and their ability to formulate research questions. We conducted a laboratory course in microbiology in which the laboratory techniques were presented in an explicit and generalized manner, in the context of specific research questions. During the course, teachers' understanding of laboratory techniques improved as reflected in their answers to exercises given throughout. In addition, teachers' ability to ask research questions, analyzed using Dillon's classification of research questions, also improved. When reflecting upon the course, some teachers attributed the change in their ability to ask research questions to their increased knowledge of techniques, whereas others did not. We conclude that to facilitate research‐question‐asking skills among teachers, they should be provided with knowledge of the relevant laboratory techniques in an explicit fashion. © 2012 Wiley Periodicals, Inc.

Assessing Teachers’ Pedagogical Knowledge in the Context of Teaching Higher‐order Thinking     

Anat Zohar  Noa Schwartzer 《International Journal of Science Education》2013,35(13):1595-1620

This article reports the development and application of two instruments for assessing science teachers’ pedagogical knowledge in the context of teaching higher‐order thinking: a Likert‐type research instrument, and an instrument that analyzes classroom observations. The rationale for developing these instruments and their main categories is described. One hundred and fifty Israeli science teachers replied to the Likert‐type questionnaire. Results show that biology teachers gained a significantly higher score than either physics or chemistry teachers, that junior high school teachers scored significantly higher than high school teachers, and that a significant negative correlation was found between final scores and teaching experience. Participants in the classroom observation study were 14 teachers who attended a one‐year professional development course for teaching higher‐order thinking. The instrument was sensitive in detecting progress in teachers’ pedagogical knowledge in several categories, such as: Frequency of tasks that required higher‐order thinking; The variety of thinking strategies that teachers addressed during their lessons; Engagement of students in metacognitive thinking; and Using the “language of thinking” in class. The implications of the findings for research and practice are described.  相似文献   

Israeli college students’ perceptions of internationalisation     

Miri Yemini  Vered Holzmann  Dalia Fadilla  Nazeh Natur  Anat Stavans 《International Studies in Sociology of Education》2013,23(3):304-323

In the last two decades, higher education institutions have invested significant resources to internationalise, due to economic, political, academic and cultural pressures. Students play a dual role in this process: as customers, selecting institutions based on respective reputations (including the international dimension) and as outputs of institutional internationalisation processes aiming to produce internationally oriented graduates. Universities aspire towards integration of international, global and intercultural dimensions as main aims of higher education, reflecting the upsurging prominence of cosmopolitan capital among their future graduates. Indeed, cosmopolitanism is increasingly considered desirable on individual and institutional levels. Using data from a student survey (n = 1650) gathered at seven geographically and otherwise diverse colleges in Israel, this paper investigates Israeli college students’ perceptions of internationalisation and estimation of their institutions’ internationalisation activities. Parents’ education, previous experiences abroad, proficiency in English and institutional efforts to internationalise were found to positively impact students’ perceptions of on-campus internationalisation initiatives and characteristics. Such differences were also found to relate to the university’s general status and context. This paper presents the findings of the survey and discusses possible implications for policy and practice at institutional and national levels.  相似文献   

School Religious-Cultural Attributes and School Principals’ Leadership Styles in Israel     

Anat Barth  Pascale Benoliel 《Religious education (Chicago, Ill.)》2013,108(4):470-485

Schools in Western cultures, including Israel, have been transformed from closed to open systems. This change is especially important to the principal’s role and leadership style. This article seeks to investigate the cultural-religious differences in Israeli Jewish principals’ leadership styles. Data were collected from 1,859 teachers, 34% from ultra-Orthodox schools, 50% state-religious schools, and 16% from state-secular schools. Regression results support the study's main hypotheses: cultural-religious orientation explains participative and transactional leadership styles but not transformational leadership. We discuss the implications of these findings for both theory and practice.  相似文献   

Activity and Action: Bridging Environmental Sciences and Environmental Education     

Tali Tal  Anat Abramovitch 《Research in Science Education》2013,43(4):1665-1687

The main goal of this study was to examine the Environmental Workshop unit taught to Environmental Sciences majors in the high schools in Israel and learn if, and in what ways, this unit could become a model for environmental education throughout the high school curriculum. We studied the special characteristics of the Environmental Workshop (EW) unit, which is based on inquiry-based learning that takes place in and out of school, and includes an environmental action component as well. We describe three approaches to the EW we identified. After identifying teachers’ challenges in assessing their students, in addition to the phenomenographic study, we suggest and demonstrate assessing the EW students by relevant socio-scientific issues. Finally, we argue that the EW could be incorporated in the junior as well as the high school curriculum as a coherent unit that is in line with environmental education in its broader sense.  相似文献   

The Persistence of Solid and Liquid Naive Conceptions: A Reaction Time Study     

Reuven Babai  Anat Amsterdamer 《Journal of Science Education and Technology》2008,17(6):553-559

The study explores whether the naive concepts of solid and liquid persist in adolescence. Accuracy of responses and reaction times where measured while 41 ninth graders classified different solids (rigid, non-rigid and powders) and different liquids (runny, dense) into solid or liquid. The results show that these naive conceptions affect adolescences’ classifications in terms of both accuracy and reaction time. The rate of correct classifications of non-rigid solids and powders was significantly lower than of rigid solids. Lower rate of success was also found for classification of dense liquids compared with runny liquids. In addition, the reaction time results of correct classifications for non-rigid solids and powders were longer than those for rigid solids and, likewise, reaction times for dense liquids were longer than for runny ones. These results suggest that reasoning processes associated with correct classification of objects that are not consistent with the naive conceptions are more demanding.  相似文献
