Junior high school students' astronomy conceptions were analysed by means of a written questionnaire presented to them during the beginning of the first semester. The main findings were as follows: almost half of the students indicated that the cause of the day-night cycle is the Earth spinning on its axis; most students chose as their best account for changes in the Moon's phases the Moon moving around the Earth. Despite that, most students thought that the Moon must be in its Full phase for there to be a total solar eclipse; most students underestimated the distances in the Universe and overestimated the Earth's diameter. A great proportion of students indicated that the reason for the different seasons is the tilt of the Earth's axis relative to the plane of its orbit as it revolves around the Sun. But almost the same number of students chose the varying distance between Sun and Earth or between the Earth, Moon and Sun, as a reason for the seasons. Only a third of the students answered correctly that in Israel's latitude, north of the Tropic of Cancer, the Sun is never directly overhead at noon; most students chose the correct estimate of a month for the Moon revolving around the Earth and a year for the Moon going around the Sun; about a third of the students chose the correct answer that when it is noon in Haifa, it would be about sunset in Beijing (90° east of Haifa). Few students indicated that the fact that we always see the same side of the Moon from the Earth implies that the Moon rotates on its axis once a month.  相似文献

ABSTRACT

Alternative conceptions in astronomy are a road block to new learning. Astronomy content is included in the Australian Curriculum (AC) from Year 3 and then intermittently in Year 5, Year 7 and Year 10. In accepting that science is socio-culturally constructed, it is important for teachers to have a clear understanding of the alternative conceptions that students bring with them to the science classroom. This article reports on the alternative conceptions elicited from 546 students ranging from Year 5 through Year 7 using a modified form of the Astronomy Diagnostic Test [Danaia, L. (2006). Students’ experiences, perceptions and performance in junior secondary school science: An intervention study involving a remote telescope (Doctoral dissertation). Charles Sturt University, Bathurst]. Results show that some well identified alternative conceptions, such as the ‘eclipse model’ to explain the phases of the Moon, exist before students enter high school and prior to any formal learning on the topic. In addition, this research identified a number of alternative conceptions held by pre-adolescent students in Western Australia that were based on knowledge that should have been consolidated by students in Year 3, viz., the relative movements of the Earth, Moon and Sun. Armed with students’ alternative conceptions as a part of their pedagogical content knowledge, teachers can construct active learning experiences that will challenge students’ existing constructs in order to allow for new learning. This sample suggests that we need to identify the reasons behind the lack of consolidation of the foundation astronomy content of the Australian Curriculum outlined for students in Year 3.  相似文献

Understanding of the Earth/Sun/Moon system represents a major cultural nexus in the history of ideas as well as being an important conceptual area in junior science teaching. The situation is one in which the objects in question can be observed but do not lend themselves to hands‐on experience in the case of the Sun and Moon or to obvious meaningful experience of the system in the case of the Earth.

Children from 9 to 12 years of age were questioned using a clinical interview technique and stimulus materials, about the shape, size and motion of the Earth, Sun and Moon. A number of alternative views appear to be held. The use of a similar procedure with a group of children would seem to offer a powerful teaching methodology in which both teacher and students gain from the dialectic learning situation that is developed by this technique ‐ apart from providing insights concerning children's understanding.  相似文献

The abundance of images concerning textbooks doesn't always facilitate the understanding of the concepts. In this study, the phases of the moon, the images shown in Primary and Secondary textbooks, the relationships between the written theoretical content and its illustration, as well as the problems of comprehension of some images, are studied. We worked with 78 students in the third year of a university teacher-training course. The images used to illustrate the phases of the moon are not, by themselves, sufficiently explanatory . Students haven't a clear idea of the Sun/Earth/Moon model and they lack some concepts with which to build it. They have also difficulty in expressing themselves in diagrams. Very strong inducements to attract attention are required in the written text, as well as specific instructions on the part of the teacher, if learning is to take place.  相似文献

Children's understandings of the shape and relative sizes of the Earth, Sun and Moon have been extensively researched and in a variety of ways. Much is known about the confusions which arise as young people try to grasp ideas about the world and our neighbouring celestial bodies. Despite this, there remain uncertainties about the conceptual models which young people use and how they theorise in the process of acquiring more scientific conceptions. In this article, the relevant published research is reviewed critically and in-depth in order to frame a series of investigations using semi-structured interviews carried out with 248 participants aged 3–18 years from China and New Zealand. Analysis of qualitative and quantitative data concerning the reasoning of these subjects (involving cognitive categorisations and their rank ordering) confirmed that (a) concepts of Earth shape and size are embedded in a ‘super-concept’ or ‘Earth notion’ embracing ideas of physical shape, ‘ground’ and ‘sky’, habitation of and identity with Earth; (b) conceptual development is similar in cultures where teachers hold a scientific world view and (c) children's concepts of shape and size of the Earth, Sun and Moon can be usefully explored within an ethnological approach using multi-media interviews combined with observational astronomy. For these young people, concepts of the shape and size of the Moon and Sun were closely correlated with their Earth notion concepts and there were few differences between the cultures despite their contrasts. Analysis of the statistical data used Kolmogorov–Smirnov Two-Sample Tests with hypotheses confirmed at K–S alpha level 0.05; rs : p?<?0.01.  相似文献

ABSTRACT:

The influence of the earth education program, Sunship Earth, on ecological knowledge and environmental attitudes was examined. It was found that students who attended the Sunship Earth program increased their ecological knowledge significantly. Participation in the Sunship Earth program did not result in more positive environmental attitudes. Part of the success of the Sunship Earth program is attributed to the setting in which it occurs and the techniques used to develop ecological concepts. The need for more opportunities for teachers to develop skills in environmental education and to participate in environmental education curriculum development that would link extension education more firmly to the school curriculum is discussed.  相似文献

Abstract

Although the number of engineering students is increasing, dropout rates remain high. This problem is also present in the Faculty of Engineering Technology (FET) at KU Leuven, Belgium, which resulted in the need for an in-depth analysis of the academic achievement of the bridging students there. This study examines the contribution of a range of predictors, both cognitive and non-cognitive. The examined predictors are: general characteristics, academic background variables and variables tested in a diagnostic test. A multiple linear regression model for the 2015–2016 chohort accounted for an explained variance of 36% of the students’ academic achievement. After combining three cohorts, we managed to explain 43% of the variance in students’ academic achievement. As expected, the academic background variables are the most important predictors. The diagnostic tests are less predictive but their role is important, since they encourage students to participate in associated interventions.  相似文献

This paper reviews astronomy education research carried out among school students, teachers, and museum visitors over a 35‐year period from 1974 until 2008. One hundred and three peer‐reviewed journal articles were examined, the majority of whose research dealt with conceptions of astronomical phenomena with 40% investigating intervention activities. We used a conceptual framework of “big ideas” in astronomy, five of which accounted for over 80% of the studies: conceptions of the Earth, gravity, the day–night cycle, the seasons, and the Earth–Sun–Moon system. Most of the remaining studies were of stars, the solar system, and the concepts of size and distance. The findings of the review have implications for the future teaching of, and research in, the discipline. Conceptions of the Earth and the day–night cycle are relatively well‐understood, especially by older students, while the Moon phases, the seasons, and gravity are concepts that most people find difficult both to understand and explain. Thoroughly planned interventions are likely to be the most effective way of implementing conceptual change, and such studies have been well‐researched in the past 15 years. Much of this recent research has worked with constructivist theories resulting in methodological and theoretical insights of value to researchers and practitioners in the field. It is recommended that future research should work across the disciplinary boundaries of astronomy education at school and teacher education levels, and aim to disseminate findings more effectively within the education systems.  相似文献

Abstract

The relative effectiveness of a problem-solving-based computer-assisted instruction (PSCAI) and a lecture-Internet-discussion instruction (LIDI) were compared for Taiwan senior high school students' science achievement and attitudes toward science. A pretest-posttest control group experimental design involving 8 classes was used. Experimental-group students (n = 156) received the PSCAI; comparison-group students (n = 138) received the LIDI. Instruments included the Earth Science Achievement Test (C. Y. Chang, 2000) and the Attitudes Toward Earth Science Inventory (C. Y. Chang & S. L. Mao, 1999). A multivariate analysis of covariance suggested that (a) students taught using the PSCAI scored higher but not significantly higher than did students in the LIDI group and (b) there were statistically significant differences in favor of the PSCAI on student attitudes toward the subject matter.  相似文献

Senior high school students' astronomy conceptions were analysed by means of a written questionnaire presented to them during the beginning of the first semester. The main findings were: (1) Most students answered correctly the questions dealing with the following subjects: the day-night cycle, the reason for the different seasons, and the time of the Moon's revolution around the Earth and the Sun. (2) Most students chose their best account for changes in the Moon's phases as the Moon moving around the Earth. Despite that, most students thought that the Moon must be in its full phase in order to get a total solar eclipse. (3) Most students underestimated distances in the Universe and overestimated the Earth's diameter. (4) Most students answered incorrectly the questions dealing with the following subjects: Sun overhead at noon, longitude time zones, and Moon's rotation. (5) Students studying physics succeeded significantly better than their colleagues in some of the subjects that were taught as a part of their optics and mechanics courses.  相似文献

Abstract

One hundred and eight children aged between seven and 11 took part in a cross‐sectional study of the development of their concepts of the Earth and the direction of its gravitational field. A new form of ‘Earth drawing classification’ (EDC) was found to be drawn by 36% of the sample, together with the five classifications established in earlier work. This new EDC is conceptually contradictory and appears to be a critical development stage. It is the result of the pupils’ attempts to reconcile scientific information with their own common‐sense knowledge base. The educational implications of this are discussed. The relationship between the developmental sequence of their Earth drawings and the quality of their human figure drawing was also investigated. It was established that restricted drawing ability does not explain their non‐scientific early EDCs.  相似文献

ABSTRACT

Male students with immigrant backgrounds are disproportionally referred for special educational support outside regular classrooms or schools, which may reflect differential teachers’ expectations concerning the academic achievement of students based on sociodemographic characteristics. Although research has indicated differential teachers’ expectations for students based on immigrant background or special educational needs (SEN), less is known about a possible double vulnerability associated with combined stereotypes. Therefore, in the current study, both SEN and immigrant background were systematically varied and teachers were asked to rate the students’ academic achievement. Results showed that teachers’ expectations of students with SEN and immigrant background were lower than for students without immigrant background, especially in regards to language proficiency. These results may help to explain the overrepresentation of students with immigrant background in special education programmes. The educational and theoretical implications of these findings are discussed.  相似文献

Previous empirical studies using multiple‐choice procedures have suggested that there are misconceptions about the scale of astronomical distances. The present study provides a quantitative estimate of the nature of this misconception among US university students by asking them, in an open‐ended response format, to make estimates of the distances from the Earth to the Moon, to the Sun, to the nearest star, and to the nearest galaxy. The 83 participants were asked to give their estimates on a scale with the Earth the size of a baseball, using a familiar local landmark for its position, and asked to indicate the appropriate location of the other astronomical objects on this scale. These psychological estimates were then compared to the actual physical distances. The data showed that while there is great variation, a general pattern emerged that US undergraduate participants overestimated the distance from the Earth to the Moon, moderately underestimated the distance from the Earth to the Sun, and dramatically underestimated the distances to the nearest star and to the nearest galaxy. The results suggest that these distance misconceptions should receive direct instructional attention in science courses.  相似文献

Abstract

Active teachers noted persistent problems in their classrooms, including low levels of student engagement and gaps in students’ use of evidence in forming arguments. Earth Science students provided written responses to two questions using the previously implemented Claim, Evidence, Reasoning (CER) framework. The first question was answered without a preceding discussion whereas the second question was answered following a discussion protocol—no discussion, discussion without Talk Science, and discussion with Talk Science. A ninth grade teacher more comprehensively implemented Talk Science by incorporating statements from all four goals whereas a seventh grade teacher did not. As a result, ninth grade students improved their use of evidence, reasoning, and content, but seventh graders did not show the same improvements. All students valued the discussion, but this study shows that Talk Science discussions can be used to improve students’ content knowledge and CER argumentation skills.  相似文献

Abstract

Math and science textbook chapters invariably supply students with sets of problems to solve, but this widely used approach is not optimal for learning; instead, more effective learning can be achieved when many problems to solve are replaced with correct and incorrect worked examples for students to study and explain. In the present study, the worked example approach is implemented and rigorously tested in the natural context of a functioning course. In Experiment 1, a randomized controlled study in ethnically diverse Algebra classrooms demonstrates that embedded worked examples can improve student achievement. In Experiment 2, a larger randomized controlled study demonstrated that improvement in posttest scores as a result of the assignments varies based on students’ prior knowledge; students with low prior knowledge tend to improve more than higher knowledge peers.  相似文献

ABSTRACT

Racial segregation has remained a lasting legacy of rural schools in southern states. Our article explains a case where community leaders created a diverse charter school to change its historical practice of an isolated White private school and isolated African American public schools. We scan documents and literature related to this integration strategy to surface key themes when using rural charter schools to alter patterns of school segregation. First, we explain pressing issues in rural schools. Second, we describe how segregation and inequality have evolved in the South. Third, we explain research showing how charter schools maintain patterns of school segregation, but with exceptions and nuances in certain contexts. Fourth, we consider the benefits and tensions surrounding one rural charter school that offers an integrated educational program. Benefits range from societal to individual as the school fosters an environment where students are exposed to diverse educational experiences. Tensions include shifting power and funding dynamics and the possibility of using a good example to shepherd in less effective charter models elsewhere.  相似文献

Abstract

We present ideas about concepts underlying climate change, held by students in years 9 and 10. Misconceptions about climate change are common among students, and may be due to misconceptions about underlying concepts. To investigate this, we developed the Climate Change Concept Inventory (CCCI), and trialed it with 229 students; corroborating findings through focus group interviews. Our interview method and data analysis methods are described. Findings included overestimation of human contributions to atmospheric carbon inputs, ultra violet radiation in sunlight, and greenhouse gases in the atmosphere. Students were unaware that CO2 dissolves in water, and of the role of oceans in the carbon cycle. Greenhouse gases other than CO2 were rarely known. Earth’s energy balance and black body radiation were not well understood. There were misconceptions about interactions between electromagnetic radiation and atmospheric gases; and limited understanding of carbon chemistry. The CCCI is available from the corresponding author.  相似文献

This paper reports an examination on gender differences in lunar phases understanding of 123 students (70 females and 53 males). Middle‐level students interacted with the Moon through observations, sketching, journalling, two‐dimensional and three‐dimensional modelling, and classroom discussions. These lunar lessons were adapted from the Realistic Explorations in Astronomical Learning (REAL) curriculum. Students’ conceptual understandings were measured through analysis of pre‐test and post‐test results on a Lunar Phases Concept Inventory (LPCI) and a Geometric Spatial Assessment (GSA). The LPCI was used to assess conceptual learning of eight science and four mathematics domains. The GSA was used to assess learning of the same four mathematical domains; however, the GSA test items were not posed within a lunar context. Results showed both male and female groups to make significant gains in understanding on the overall LPCI test scores as well as significant gains on five of the eight science domains and on three of the four mathematics domains. The males scored significantly higher than the females on the science domain, phase—Sun/Earth/Moon positions, and on the mathematics domain geometric spatial visualisation. GSA results found both male and female groups achieving a significant increase in their test scores on the overall GSA. Females made significant gains on the GSA mathematics domains, periodic patterns and cardinal directions, while males made significant gains on only the periodic patterns domain. Findings suggest that both scientific and mathematical understandings can be significantly improved for both sexes through the use of spatially focused, inquiry‐oriented curriculum such as REAL.  相似文献

ABSTRACT

This essay attempts to explore the links between politics, poetry, and collective, embodied readings and discussion in the classroom. When my Year 12 class were asked ‘What is Poetry?’, their answers suggested something in the Romantic tradition – of poetry as expressive, individual and emotional. My experience studying poetry with my Year 9 class suggests something altogether different – that studying poetry allows students to have an embodied and collective reading. In the sense that politics concerns the control of bodies, poetry allows the class to read in an embodied sense, thus politically, in a way that assessment criteria and the demands of high-stakes testing, with their focus on individual understanding, do not. Thus, I argue for the study of poetry as essential in terms of recognising students’ political agency – not primarily as exam-takers but as citizens of a country and an Earth they will, to put it grandly, inherit.  相似文献
