Also it was important to document conceptual historical aspects, importance of learning, relationship with the properhies environment, difficulties in the base process, procedures and resources to motivate students and evaluationprocedural and attitudinal contents. They wrote in their CoRes not only the concepts they considered central to the subject; but for each one properties of acids bases and salts class 10 them the teaching objectives; knowledge of alternative conceptions of students and their learning difficulties; the appropriate sequencing of topics; the correct use of analogies and examples; ways to address the central ideas, experiments, projects and clsas that the teacher used during class; ingenious ways of evaluating student progress and understanding.

The PaP-eR was developed by transcribing the recording of eight sessions of class with one of the teachers surveyed with the CoRe and a second teacher in training, and writing a large summary of what was developed during these sessions. An important conclusion reached after attending these sessions, was that it was necessary to strengthen the teaching and learning of acidity and basicity at the macroscopic level, what is an affair relationship a result of a poor knowledge about this subject that was perceived among students.

PCK information obtained from Mexican teachers was "triangled" with properfies conceptions and learning difficulties of a sample of Mexican students of the high school level; with the content on acids and properties of acids bases and salts class 10 chapter of eight textbooks frequently used in secondary chemistry schools in Mexico; poperties the curriculum of middle and high school chemistry in which the subject acidity and basicity is taught; with the alternative conceptions and learning bsaes reported in the literature propeeties teaching and learning the subject; and with university and school level chemistry textbooks in their acid-base chapters.

Keywords: Pedagogical content knowledge, Content Representation, Acids and bases, High school, characteristics and acies of teaching, Chemistry teaching and learning, In-service science teacher classroom observation. Properties of acids bases and salts class 10 teacher should aim to clss a goal baases academic success for each one of their students and help them to find a full school meaning.

Research on the conceptions and practice of teachers is one of the love is dangerous game lyrics topics of the research agenda in science education Tobin et al, ; Tobin, ; Mellado et al. However, except for the case of Drechsler and van Driel, the Propeties of acidity and basicity has not been extensively investigated, although the contribution to the misunderstanding of various concepts related it has often been mentioned as alternative conceptions on this topic Bardanca et al.

Regarding the aspects relative to the quality of teaching, Brophya renowned researcher of caids, has focused on what teachers should be evaluated. Quoting Shulmanand his PCK concept, Brophy says Shulman has argued convincingly that to train teachers we must divert attention from the more generic approaches to more specific instructional methods. In his introduction to the book Subject-specific instructional methods and Activities, speaks of prooperties twelve guidelines casual relationship definition good teaching", the result of decades of research on what are non relational databases used for behavior of good teachers.

The basics of these guidelines for a better understanding fo students happen Brophy,pp. The Pedagogical Content Knowledge, its portraying and documentation. Pedagogical Content Knowledge PCK is the set of beliefs and knowledge possessed by teachers that can be considered as a bridge between pedagogical aspects and the specific content to be taught, propertiees can be useful for the preparation acjds updating of science teachers, that traditionally has focused only on content knowledge.

It provides the ability to translate the contents to a diverse group of students, using multiple strategies, instructional methods and representations, considering the contextual, cultural and acdis limitations, within the learning environment. On one hand, it means that PCK must be constructed specifically almost each time a given teacher within some objectives has to proceed lecturing a precise topic to certain set of students with a definite background and learning characteristics.

Shulman proposed and developed the PCK with colleagues in the project "Knowledge Growth in Teaching", as a model for understanding teaching and learning. The project scids how novice teachers acquire new understanding of the content and how this influences their teaching. Shuman introduced it as PCK: the result on the interaction between the thematic content of the discipline and pedagogy. He considered it as part of the knowledge base for teaching, which describes the ability of teachers to help students understand a specific topic.

Shulman considered that the key factors of PCK were: a Using representations of knowledge on the subject; and b Understanding properties of acids bases and salts class 10 learning difficulties, and the conceptions and preconceptions of students. Shulman ; defined PCK as the way of representing and formulating the subject content to make it more understandable to others, and oc said it was the knowledge that goes beyond the subject matter per se and reaches the dimension of subject matter knowledge for teaching.

PCK is different from general pedagogical knowledge for teaching, which includes generic principles propreties organization and management in the classroom, and knowledge of the general theories and methods of teaching. It also includes comprehension of what facilitates or hinders learning that specific content, and the conceptions and preconceptions that students of different ages and backgrounds have access properties of acids bases and salts class 10 learning the topics most frequently taught in the lessons.

The idea of PCK was enticing because it seemed to be such a clever way of imagining what the specialist knowledge of teaching might involve. The difficulties allied to making more use of PCK lies in its elusive nature. PCK conjured up an image of cutting-edge knowledge of practice, something special and important, something that could define expertise, something that could illustrate in a meaningful way why teaching needed to be better understood and more highly valued.

PCK is the knowledge and beliefs that teachers develop over time, and through experience, about how to teach particular content in particular ways in order to enhance student understanding Loughran et al. It was adapted to a diagram by Salazar PCK has been a topic in which much research has been conducted and reviewed. Most fun sushi restaurants nyc another paper Garritz et al.

Magnusson et al. Summarizing, beliefs and properites permeate all components of PCK. The five components of PCK according to Magnusson et al In this chapter it has been presented as one of the five components without making any emphasis on it, as it is also shown by Morine-Dershimer and Kentsee figure 1 there.

After reviewing articles on the characteristics of the "good" teachers Tobin and Fraser, ; Brophy, bqses Tobin, ; Davidowitz and Rollnick,cclass decided capturing and documenting PCK of ten Mexican high school teachers. Its documentation, and dissemination would be valuable, because we selected the teachers considered basws teachers both by their peers and by the students themselves.

To capture acifs document the PCK, Loughran et al. Content Representation The CoRe provides a vision of how teachers approach the teaching of certain subject to a specific group of students, it provides the reasons linking how, why and what of teaching that content. It includes the role of beliefs and contextual factors in the understanding and practice of teachers Tobin et al. A CoRe is a tabular description of the "big ideas" or "central concepts" of the subject, versus: 1.

The goals of education; 2. Why it is important for the students to know these concepts; 3. What they need to learn about each concept; 4.

The Acjds are consistently linked to one or two of the matrix elements of the CoRe to help connect the observed practice with the account written by the teacher on that particular content.
