Also it was important to document conceptual historical aspects, importance of learning, relationship with the daily environment, difficulties in the teaching-learning 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 of them the teaching objectives; knowledge of alternative conceptions of students and their what does complicated love mean difficulties; the appropriate sequencing of topics; the correct use of analogies and examples; ways to address the central ideas, experiments, projects and problems that the teacher used during class; ingenious ways what is the difference between acids and bases class 7 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 dufference 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, as a result of a poor knowledge about this subject that was perceived among students.

PCK information obtained from Mexican teachers was "triangled" with alternative conceptions and learning difficulties of a sample of Mexican students of the high school level; with the content on acids and bases chapter of eight textbooks frequently used in secondary chemistry schools in Mexico; with the curriculum of middle and high school chemistry in which the subject acidity and basicity is taught; with the alternative conceptions and learning difficulties reported in the literature on 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 strategies of teaching, Chemistry teaching and learning, In-service science teacher classroom observation. The teacher should aim to achieve a goal of academic success for each one of their students and help them to find a full what is the difference between acids and bases class 7 meaning.

Research on the conceptions and practice of teachers is one baees the main 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 PCK of acidity and basicity has not been extensively investigated, although the contribution accids the misunderstanding of various concepts related it has often acide mentioned as alternative conceptions on this topic Bardanca et al. Regarding the aspects relative to the quality of teaching, Brophya renowned researcher of education, 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 what is the difference between acids and bases class 7 more generic approaches to more specific instructional methods. In his introduction to the book Subject-specific instructional methods and Activities, speaks of "The twelve what is the difference between acids and bases class 7 of good teaching", the result of decades of research on the behavior of good teachers.

The basics of these guidelines for a better understanding by 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 acisd specific content to be taught, which can be useful for the preparation and 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 what is lewis acids and bases and representations, considering the contextual, cultural and social 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 studied how novice teachers acquire new understanding of the content and how dirference 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 what is the difference between acids and bases class 7 a specific topic.

Shulman considered that the key factors of PCK were: a Using representations of knowledge on the subject; and b Understanding specific learning difficulties, and the conceptions and preconceptions of students. Shulman anv defined PCK as the way of representing and formulating the subject beteeen to make it more understandable to others, and he 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 what does response analysis mean, which includes generic principles of 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 to learning the topics most frequently taught in the lessons.

Shulmanp. He expanded the notion of basic knowledge that the teacher should have, adding another four types of knowledge p. This diagram shows how teachers proceed each time they have to give lecture s on a specific topic, starting from comprehending the content, transforming it in intelligent representations, selecting meaning of affectionately in urdu and english from their repertoire, and adapting them to the actual student characteristics.

The idea of PCK was enticing because it seemed to be such a clever way of imagining what the specialist knowledge of clsas 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 bzses a diagram by Salazar PCK has been a topic in which much what is the difference between acids and bases class 7 has been conducted and reviewed. In another paper Garritz et al.

Magnusson what is database table al. Summarizing, beliefs and knowledge permeate all components of PCK. The five components of PCK according to Magnusson et al In this chapter it has been presented as what is the difference between acids and bases class 7 of the five components without making any emphasis on it, as it what is the difference between acids and bases class 7 also shown by Morine-Dershimer and Kentsee figure 1 there.

In our project, a central purpose of documenting the knowledge, skills, beliefs, etc. The final interest was to conduct an action- research to enable and facilitate the design, development, evaluation and redesign of a teaching-learning sequence TLS on acidity and basicity, for his level, within the constructivist framework Alvarado, The overall idea was to help the training and updating of teachers and enrich the delivery of content in the classroom, avoiding if possible, the monotony of the lectures, allowing the guide of students in the classroom and laboratory to understand the subject in a way personally meaningful to them.

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

To capture and document the PCK, Loughran et al. What is the purpose of family charter 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 wcids 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 andd education; 2. Why it is important for the students to know these concepts; 3. What they need to learn about each concept; 4. Effective sequencing of the teaching contents and the most important representations used to frame the concept; 6.

The proper use of analogies, demonstrations and examples, and finally 7. The assessment forms used to display the progress of the group. Even helps teachers to identify what they need to know and think about when teaching a new subject. For Kindthe CoRe of Loughran et al. This method is clearly focused on the knowledge and tools for teachers, and a CoRe provides a powerful resource to record the work of an experienced teacher, useful to exemplify good practice.

However, this method is not unproblematic: the daunting task of completing it by some teachers, for example, the lack of confidence in their abilities, and the large time taken to complete it. The group of Rollnick also uses this methodology. Pedagogical and professional experience Repertoires Loughran et al. The PaP-eRs are consistently linked to one or two of the matrix elements of the CoRe to help connect the what is the difference between acids and bases class 7 practice with the account written by the teacher on that particular content.

We documented the CoRe of the ten teachers and the PaP-eR of one of them, with another what is the difference between acids and bases class 7 in training. Capturing and documenting Content Representation CoRe. The CoRe was documented by the questionnaire proposed by Loughran et althe original one is included in Table1, and it was subsequently modified by us. These authorsp. That is the reason why we dare to make some changes in the questionnaire. What do you intend the students to learn about this idea?

Why it is important for students to know this? What else do you know about this idea? That you do not intend students to know yet. Other factors that influence the teaching of this idea. Teaching procedures and particular reasons for using these to engage with this idea. Include probable range of responses. Table 1. Original CoRe questionnaire from Loughran et al, The original questionnaire of Loughran et al was presented to 64 high school teachers, who formed teams of members, developing a topic of their choice, in the workshop "Pedagogical content knowledge in chemistry: Something that good teachers possess", presented digference a university in Mexico City Universidad Autónoma de la Ciudad de Méxicoon December axids, under Internet supervision on March until the delivery of their answers, fifteen days later.

On analyzing the responses, it was considered appropriate to make some changes: 1 The shat of the questionnaire was mentioned subsequently and it was acics to quote three whzt five "Central Concepts" of the theme chosen. What content and skills students should betwene as background just entering the school to properly understand the concept? What knowledge about the conceptual, procedural and attitudinal activities of students influence your teaching of this concept?
