Teachers’ and Students’ Conceptions of Good Science Teaching

Capitalizing on the comments made by teachers on videos of exemplary science teaching, a video-based survey instrument on the topic of ‘Density’ was developed and used to investigate the conceptions of good science teaching held by 110 teachers and 4,024 year 7 students in Hong Kong. Six dimensions of good science teaching are identified from the 55-item questionnaire, namely, ‘focussing on science learning’, ‘facilitating students’ understanding’, ‘encouraging students’ involvement’, ‘creating conducive environment’, ‘encouraging active experimentation’ and ‘preparing students for exam (PSE)’. Significant gaps between teachers’ and students’ conceptions on certain dimensions have been revealed. The inconsistency on the dimension ‘PSE’ is particularly evident and possible reasons for the phenomenon are suggested. This study raises the important questions of how the gap can be addressed, and who is to change in order to close the gaps. Answers to these questions have huge implications for teacher education and teacher professional development.     

The Research of College Students’ English Classroom Behavior Investigations

By employing quantitative research methods, the paper investigates college students' preferences to English classroom behaviors and the relations between behaviors and achievements. The results indicate that there are significant differences among the subjects' behavior, cognitive and emotional elements, and their classroom behaviors are mainly visual, individual, imitative and exterior-motivated; there are significant differences in behavior element and emotional element between high-result group and low-result group; confident and oral classroom behaviors have prominent relations with CET-4 achievements, and different teaching methods may make learning behaviors produce good or bad effects to achievements.     

Elementary and Middle School Students’ Conceptions of Knowledge,Information, and Truth

Although the study of epistemic beliefs has received growing interest in the past decades, this research tends to focus on high school and undergraduate students, and does not address beliefs about information and truth, concepts that have been regarded as critical for learners in 21st-century educational contexts. In this study, the authors examined 87 elementary and middle school students’ beliefs about the definitions of and relations among knowledge, information, and truth through the use of a graphical and justification task, and addressed the consistency of beliefs across contexts and domains. Results indicated that students tended to regard knowledge, information, and truth as interrelated, and the majority of students described their beliefs as consistent across contexts and domains.

Muslim Egyptian and Lebanese Students’ Conceptions of Biological Evolution

In this study, we investigated distinctions among the diversity of religious traditions represented by Lebanese and Egyptian Muslim high school students regarding their understanding and acceptance of biological evolution and how they relate the science to their religious beliefs. We explored secondary students’ conceptions of evolution among members of three Muslim sects—Sunni, Shiite, and Druze—in two cultural contexts; one in which the overwhelming majority of the population is Muslim (Egypt) and another in which there is a sizable Christian community (Lebanon). Data were collected via surveys that examined students’ scientific and religious understandings of evolution among 162 Egyptian students (all Sunni Muslims; 63% females and 37% males) and 629 Lebanese students (38.5% Sunni, 38% Shiite, and 23.5% Druze; 49% females and 51% males). Additional data were collected via semi-structured interviews with 30 Lebanese students to allow triangulation of data for accuracy and authenticity. Results indicate that many Egyptian and Lebanese Muslim students have misconceptions about evolution and the nature of science which often lead to rejection of evolution. Also, Lebanese Sunni and Shiite students and Egyptian Sunni students tend to exhibit high levels of religiosity, and these students report that their religious beliefs influence their positions regarding evolution. Finally, Sunni and Shiite Lebanese students have religious beliefs, conceptions of evolution, and positions regarding evolution similar to those of Sunni Egyptian students. These conceptions and positions, however, are substantially different from those of Druze Lebanese students.     

Relational Analysis of College Science‐Major Students’ Epistemological Beliefs Toward Science and Conceptions of Learning Science

In recent years, there has been an increasing interest among educational researchers in exploring the relationships between learners’ epistemological beliefs and their conceptions of learning. This study was conducted to investigate these relationships particularly in the domain of science. The participants in this study included 407 Taiwanese college science‐major students. All of them responded to two major questionnaires, one assessing their scientific epistemological beliefs (SEBs) and the other one probing their conceptions of learning science (COLS). The SEB questionnaire included four factors: “certainty,” “source,” “development,” and “justification” of science knowledge. The COLS survey consisted of six factors in a hierarchical order, that is, learning science as “memorizing,” “preparing for tests,” “calculating and practicing,” “increasing one’s knowledge,” “application,” and “understanding and seeing in a new way.” The students’ confidence and interest toward learning science were also assessed by additional questionnaire items. Stepwise regression analyses, in general, showed coherence between students’ SEBs and their COLS, indicating that the sophistication of SEBs was consistent with less agreement with lower‐level COLS (such as “memorizing” and “preparing for tests”) as well as more agreement with higher‐level COLS (such as “understanding and seeing in a new way”). However, the SEB’s “justification” factor was positively related to almost all of COLS factors from the lower‐level to higher‐level. This study finally found that among all of the SEB and COLS factors, the “preparing for tests” factor in COLS was the solely significant variable for predicting students’ interest in science and confidence toward learning science.     

Investigating Undergraduate Science Students’ Conceptions and Misconceptions of Ocean Acidification

Scientific research exploring ocean acidification has grown significantly in past decades. However, little science education research has investigated the extent to which undergraduate science students understand this topic. Of all undergraduate students, one might predict science students to be best able to understand ocean acidification. What conceptions and misconceptions of ocean acidification do these students hold? How does their awareness and knowledge compare across disciplines? Undergraduate biology, chemistry/biochemistry, and environmental studies students, and science faculty for comparison, were assessed on their awareness and understanding. Results revealed low awareness and understanding of ocean acidification among students compared with faculty. Compared with biology or chemistry/biochemistry students, more environmental studies students demonstrated awareness of ocean acidification and identified the key role of carbon dioxide. Novel misconceptions were also identified. These findings raise the question of whether undergraduate science students are prepared to navigate socioenvironmental issues such as ocean acidification.

Students’ Alternative Conceptions about Electricity and Effect of Inquiry-Based Teaching Strategies

This study attempted to investigate the alternative conceptions that a group of 12 Lebanese students in a grade 9 class hold about electricity. It also attempted to evaluate learning outcomes of implementing in that class an inquiry-based module for the acquisition of conceptual understanding of basic concepts in electricity. Fourteen mostly subjective tests were administered throughout the implementation phase of the inquiry-based module to assess the evolution of participants’ conceptions. The instrument DIRECT (Version 1.0) focusing on conceptual understanding was used as a post-instructional test to measure acquisition of understanding. The findings revealed that most of the alternative conceptions reported in literature were found amongst the participants. Results of the post-testing showed that the implemented inquiry-based approach was successful in enhancing participants’ conceptual understanding of the targeted DC circuit concepts.     

Israeli Students’ Conceptions of Science and Views about the Scientific Enterprise

Abstract

Israeli students’ conceptions of the nature of science and views about the scientific enterprise were studied within the framework of the Second International Science Study (SISS). Representative samples of 10, 14 and 17year‐old student, about 2000 in each, responded to background questionnaires and a battery of tests and scales. The Science Understanding Measure, a 20 item, multiple choice instrument provided data on understanding the nature of science by 14 and 17 year‐olds. An Attitude toward Science Scale provided data on the views of 10, 14 and 17 year‐olds on the importance of science to society and to individuals, the usefulness of science in everyday life and on harmful aspects of science. A comparison was made between the view of Israeli, British and USA students. The relationships of the conceptions and views of 17 year‐olds with personal, home and school variables as well as with achievement in science, intentions for further learning and career aspirations were explored as well. Based on the results and conclusions some recommendations are offered on how to enhance the understanding of science and promote more positive attitudes towards the scientific enterprise     

An Exploration of Indonesian Postgraduate Students’ Conceptions of Learning

Abstract

This study sets out to explore and model selected aspects of the approaches to, and conceptions of, learning by Indonesian postgraduate students. Meyer's Experiences of Learning Inventory was administered to 105 postgraduate students at the University of Indonesia in 1995. In 1996, Meyer and Boulton‐Lewis's Reflections on Learning Inventory was administered to a separate group of 94 postgraduate students studying at the same University. An initial finding is that, for a Javanese subgroup of responses, some established operationalised constructs collectively associated with a broader ‘meaning orientation’ to learning, in particular a ‘deep approach’, exhibit low values of internal consistency (alphas between 0.18 and 0.51; ‘deep approach'= 0.28). In contrast, non‐Javanese responses exhibit acceptably higher values of internal consistency (alphas between 0.54 and 0.76; ‘deep approach’ = 0.60). Further contrasts between these two subgroups emerge in terms of exploratory factor structures (of conceptions of learning and related effects). It is argued that an understanding of variation in students’ conceptions of learning, and the influence of these conceptions on the experiences of postgraduate students, can assist supervisors and support staff to better assist them during their candidature. Such assistance, while being important for local postgraduate students, takes on an added dimension when students and supervisors are working within a cross‐cultural setting.     

College Students’ Conceptions of Chemical Stability: The widespread adoption of a heuristic rule out of context and beyond its range of application

This paper reports evidence that learners commonly develop a notion of chemical stability that, whilst drawing upon ideas taught in the curriculum, is nevertheless inconsistent with basic scientific principles. A series of related small‐scale studies show that many college‐level students consider a chemical species with an octet structure, or a full outer shell, will necessarily be more stable than a related species without such an electronic configuration. Whilst this finding is in itself consistent with previous research, the present paper shows how students commonly apply this criterion without consideration of chemical context, or other significant factors such as net charge. Species that would seem highly unstable and non‐viable from chemical considerations, such as Na^7?, C⁴⁺ and even Cl^11?, are commonly judged as being stable. This research shows that many college‐level students are privileging a simple heuristic (species with full outer shells will be stable) when asked about the stability of chemical species at the submicroscopic level, to the exclusion of more pertinent considerations. Some students will even judge an atom in an excited state as more stable than when in the ground state, when an electron is promoted from an inner shell to ‘fill’ the outer shell. It is suggested that the apparently widespread adoption of a perspective that is so at odds with the science in the curriculum is highly significant for the teaching of chemistry, and indicates the need for more detailed studies of how such thinking develops and can be challenged.     

Comparing the Utility of the 2000 and 2005 Carnegie Classification Systems in Research on Students’ College Experiences and Outcomes

This study compares the explanatory power of the 2000 edition of Carnegie Classification, the 2005 revision of the classification, and selected variables underlying Carnegie’s expanded 2005 classification system using data from the National Survey of Student Engagement’s spring 2004 administration. Results indicate that the 2000 and 2005 classifications generally offer comparable explanatory power for measures of self-reported gains and student engagement, but the new variables from the 2005 system are more strongly related to cognitive outcomes and engagement than were the two categorical groupings. The variables most consistently related to outcomes and engagement are graduate-undergraduate coexistence, residential character of the campus, and arts and sciences share of undergraduate majors. Implications of the findings for research and assessment are discussed.

The Methodology of Self-correction on College Students’ English Composition and Results

Based on the related theories of Corpus Linguistics and Error Analysis, this paper is aimed to evaluate the effect of selfcorrection through the educational experiment, with non-English major students using web corpus to identify and self-correct their errors as the subjects. To help art students improve their English writing skills, the search engine of and sentence database of online dictionary of the internet corpus are effective and helpful.     

Students’ Conceptions as Dynamically Emergent Structures

There is wide consensus that learning in science must be considered a process of conceptual change rather than simply information accrual. There are three perspectives on students’ conceptions and conceptual change in science that have significant presence in the science education literature: students’ ideas as misconceptions, as coherent systems of conceptual elements, and as fragmented knowledge elements. If misconceptions, systems of elements, or fragments are viewed implicitly as “regular things”, these perspectives are in opposition. However, from a complex dynamic systems perspective, in which students’ conceptions are viewed as dynamically emergent structures, the oppositions are lessened, and the integrated view has significant implications for theory and practice.     

College Students’ Relationship Between Trauma and Disordered Eating

Among college students, a correlation exists between trauma exposure and eating disorders. Although disordered eating behaviors are more prevalent than eating disorders, the relationship between different types of trauma exposure and disordered eating is unknown. The current study explored this relationship. One hundred two participants completed questionnaires on disordered eating and trauma exposure. Results showed that (a) sexual abuse was a significant predictor of concerns regarding food and weight gain (p < .05) and (b) other form of trauma (e.g., natural disaster) was a significant predictor of difficulties in individuals’ relationship with food (p < .05). Clinical implications, especially those related to trauma assessment and disordered eating behaviors, are discussed. The importance of examining the impact of nonsexual trauma is described, and the clinical utility of breaking eating pathology down into specific abnormal attitudes and behaviors is highlighted.
