Chemical bonding is one of the key and basic concepts in chemistry. The learning of many of the concepts taught in chemistry, in both secondary schools as well as in the colleges, is dependent upon understanding fundamental ideas related to chemical bonding. Nevertheless, the concept is perceived by teachers, as well as by learners, as difficult, with teaching commonly leading to students developing misconceptions. Many of these misconceptions result from over‐simplified models used in text books, by the use of traditional pedagogy that presents a rather limited and sometimes incorrect picture of the issues related to chemical bonding and by assessments of students' achievement that influence the way the topic is taught. In addition, there are discrepancies between scientists regarding key definitions in the topic and the most appropriate models to teach it. In particular, teaching models that are intended to have transitional epistemological value in introducing abstract ideas are often instead understood by students as accounts of ontological reality. In this review paper we provide science educators, curricula developers and pre‐service and in‐service professional development providers an up‐to‐date picture regarding research and developments in teaching about chemical bonding. We review the external and internal variables that might lead to misconceptions and the problematic issue of using limited teaching/learning models. Finally, we review the approaches to teaching the concept that might overcome some of these misconceptions. 相似文献

An inquiry-type laboratory has been implemented into the chemistry curriculum in high schools in Israel. In this study, we
investigated the idea that generally the science laboratory provides a unique learning environment that differs from the learning
environment that exists in classrooms in which other instructional techniques are used. Moreover, the inquiry laboratory provides
students with a learning situation in which they are involved in activities that might influence some of the variables that
are influencing the learning environment of such laboratories. In this study, the Science Laboratory Environment Inventory
(SLEI) was used to assess the students' perceptions of their chemistry laboratory learning environment. Statistical comparison
of two groups (control and inquiry) revealed significant differences between the groups regarding their actual perceptions.
Moreover, it was found that the differences between the actual and preferred laboratory learning environment were significantly
smaller for the inquiry group than for the control group.

This study identifies health beliefs influencing Hispanic college men's human papillomavirus (HPV) vaccine uptake decision making processes. Hispanic college men were interviewed about their HPV vaccine knowledge, and information seeking behaviors. Overall, participants did not view HPV infection or vaccination as an immediate concern or priority; belief that it was a virus that only affected women, and a sense of invulnerability informed their positions. Despite these issues, most men were willing to consider getting the HPV vaccine if they received more education from health care providers, and cost concerns were addressed. These findings pointed to gaps in our understandings of Hispanic college men's HPV vaccination beliefs and provided insight into the importance of integrating this population's unique beliefs into campus health providers efforts aimed at increasing vaccination rates. 相似文献

Proof and reasoning are fundamental aspects of mathematics. Yet, how to help students develop the skills they need to engage
in this type of higher-order thinking remains elusive. In order to contribute to the dialogue on this subject, we share results
from a classroom-based interpretive study of teaching and learning proof in geometry. The goal of this research was to identify
factors that may be related to the development of proof understanding. In this paper, we identify and interpret students'
actions, teacher's actions, and social aspects that are evident in a classroom in which students discuss mathematical conjectures,
justification processes and student-generated proofs. We conclude that pedagogical choices made by the teacher, as manifested
in the teacher's actions, are key to the type of classroom environment that is established and, hence, to students' opportunities
to hone their proof and reasoning skills. More specifically, the teacher's choice to pose open-ended tasks (tasks which are
not limited to one specific solution or solution strategy), engage in dialogue that places responsibility for reasoning on
the students, analyze student arguments, and coach students as they reason, creates an environment in which participating
students make conjectures, provide justifications, and build chains of reasoning. In this environment, students who actively
participate in the classroom discourse are supported as they engage in proof development activities. By examining connections
between teacher and student actions within a social context, we offer a first step in linking teachers' practice to students'
understanding of proof. 相似文献

The majority of studies examining the language and literacy skills of second generation immigrant bilingual children have focused on the breadth of lexical knowledge in populations with a low level of involvement in literacy activities. This study extends previous work in three ways. First, we focused on a sample of second generation immigrant bilingual children from favorable socio-cultural backgrounds. Second, we examined whether these children show lexical knowledge gaps in their second language on various measures of breadth and depth, as compared to their monolingual peers. Finally, we asked whether this gap tends to increase, remain stable, or decrease with formal schooling. Bilingual (n?=?70) and monolingual (n?=?55) children between the ages of 7 and 8?years were evaluated on measures of depth and breadth of lexical knowledge in the second language of the bilingual group. Both groups were tested twice: at the beginning of second grade and at the beginning of third grade. The findings indicate a significant gap between the target groups with respect to most measures of both depth and breadth at the beginning of second grade. However, after a year of schooling, the bilingual children showed significant progress in their lexical knowledge in their second language. The discussion addresses theoretical and clinical implications of these findings. 相似文献

AbstractThis mixed-method study sought to examine the experiences of a group of 21 pre-service teachers in a collegiate literacy education class which required a semester-long exploration of the potential of tablets to enhance the reading skills of youngsters. The quantitative portions of the study identified the participants’ daily use habits of electronic devices as well as their views on what is known as the new literacies. In the qualitative portions of the study, interviews and journal entries of the pre-service teachers were gathered relative to their experiences in devising literacy learning experiences using tablets. While these prospective teachers were avid users of electronic devises and confident in their abilities to use technology, they found considerable difficulty in preparing literacy-enhancing instruction which used tablet devices, which clearly points to the need for attention in teacher training programs to the use of tablet technology infused throughout teacher education courses. 相似文献

The study explored how a group of private Haredi (ultra-Orthodox Jewish) schools legitimized an innovative non-mandatory reform. Specifically, it examined the circumstances that facilitated and hindered a coincidence of wants between the schools and the Ministry of Education, which resulted in signing agreements that changed the status of the schools from private to public. The study drew on interviews and on various documents, including contracts, summaries of meetings, and work plans. The conclusions portray the correspondence between the top-down and bottom-up processes that facilitated the reform. At their intersection, discursive interactions transpired between the Haredi inspectors at the Ministry of Education and school leaders, reflecting a mutual aspiration toward pragmatic legitimacy. The prominent barriers to the reform derived from the Ministry of Education’s strategic assumption that a quiet, unregulated reform would generate less resistance. However, this assumption led to actions that ultimately reduced the effectiveness of the discursive interactions and their ability to produce pragmatic legitimacy. We argue that to legitimize innovative non-mandatory educational reforms in strict religious groups, the State should speak in several voices: through discursive interactions led by cultural mediators, but also through official publications, regulations, and marketing campaigns that would strengthen the reform’s pragmatic legitimacy. 相似文献

Self-assessment and peer-assessment are strategies employed to encourage students to take more responsibility for the learning process. Although the advantages are not obvious, the process has the potential to empower learning and to assist the development of assessment skills, which are so important for future teachers. The research aimed to identify student-teachers' attitudes concerning the contribution of self-assessment and anonymous peer-assessment to the quality of their assignments and improvement of their assessment skills, using both qualitative and quantitative methodologies. The sample included 300 students studying for bachelor’s or master’s degrees. Texts that were analysed included: responses to a questionnaire, self and peer-assessments, word comments on the assignments and written blog content relating to students’ activities and their performance of peer evaluations. The students noted that they significantly benefitted from the process, learned various methods of assignment and assessment performance and it positioned them in relation to others, noticing how others evaluated them. Anonymous evaluation allowed students to overcome inhibitions in evaluating peers' works and improved their assessment skills. 相似文献
