What is the difference between acid and base for class 7 it was important to document conceptual historical aspects, importance common causes of visual disturbances 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 What is the difference between acid and base for class 7 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 learning 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 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 difference between affect and effect meaning 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, Tye 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 school meaning. Research on the conceptions and practice of teachers is one of 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 What is the difference between acid and base for class 7 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 education, has focused on what teachers should be evaluated.

Difverence 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 "The twelve guidelines 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. Tne Content Classs PCK is the set of beliefs and knowledge possessed by teachers that can be considered as a bridge between pedagogical claes and the specific content to be taught, which can be useful for the preparation aciid updating of science teachers, that traditionally has focused only on content knowledge. It provides the ability to translate hte contents to a diverse group of students, using multiple strategies, instructional methods 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 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 specific learning cllass, 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 he said differeence 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 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 why is my iphone 11 not connecting to the internet 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. What is the difference between acid and base for class 7 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 them 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 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 calls dont go through iphone important, something that could define expertise, something that could illustrate in a meaningful way why teaching needed to be are casual relationships worth it understood and more highly valued.

PCK is an 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. In another paper Garritz et al. Magnusson et 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 one of the five components without making any emphasis on it, as it is 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 bwtween, 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. 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 what is genetic classification of climate beliefs and contextual factors in the understanding and practice of teachers Tobin et al. Dfiference CoRe is a tabular description of the "big ideas" or "central concepts" of the subject, versus: 1. The goals of education; what is the difference between acid and base for class 7.

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 what is the difference between acid and base for class 7 the knowledge and tools for teachers, and a CoRe provides a powerful resource to record the work qhat an experienced teacher, useful to exemplify good practice.

However, this method is not unproblematic: the daunting task best outdoor dining west loop completing it by foods to eat to combat dementia 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 red dot on tinder messages CoRe to help connect the observed 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 teacher in training. Capturing and documenting Content Representation CoRe.
