Pre Service Teacher

This study aimed to explore chemistry pre-service teacher view toward implementation of contextual learning in Organic Chemistry. The context that was investigated about is Organic Light Emitting Diodes (OLEDs), which was a novel display technology that is being used for smartphone display. Seventeen pre-service chemistry teachers were interviewed about their knowledge about organic chemistry, conjugated double bond, OLEDs and their view about implementing OLEDs context in organic chemistry learning. Three groups of questions were asked to the pre-service chemistry teacher, most of them indicating lack knowledge about detail information of OLEDs even though they really appreciate if OLEDs was introduced in Organic Chemistry learning especially in conjugated double bond and nature-generated organic compound topics.

Abstract In this paper we describe and evaluate a study on the use of concepts in organic chemistry while solving tasks that are designed after the concept of school-related content knowledge (SRCK). The study was designed as a mixed methods study and conducted at a German university for the content of “organic chemistry”. As the results of this study show, the students rate the tasks and the use of anchoring concepts as for example “bonds” or “structure and function” as relevant for their future profession as a chemistry teacher. They therefore propose that concepts should be an integral part of their university studies as they find it lacking at the moment. Concepts can also be seen as an opportunity to build a bridge between school knowledge and university knowledge.

This study aimed to determine the competence of teachers in planning and implementing chemistry learning based of curriculum 2013 case studies in class X SMA Negeri 6 Pontianak. Research subjects were chemistry teachers in class X SMA Negeri 6 Pontianak. Data collection tools used are documentation sheets, observation sheets and competency tests. Data were analyzed through data collection steps, presentation, data reduction and conclusions. Technique examination of data validity was conducted by triangulation technique and source triangulation. The result showed that the percentage of competence of chemistry teacher class X SMA Negeri 6 Pontianak in planning chemistry learning based of curriculum 2013 was 91,02% in the very high category and the percentage of competence of chemistry teacher class X SMA Negeri 6 Pontianak in implementing chemistry learning based of curriculum 2013 was 88,09% in the very high category. It showed that chemistry teacher had implemented the curriculum 2013 well.

The purpose of this study was to investigate the cognitive structures of chemistry teacher candidates about “stereochemistry”. A case study research method, one of the qualitative research patterns, was used in the study and the sample of study involved 28 prospective chemistry teachers who had taken Organic Chemistry I and II courses at Education Faculty of a middle Anatolian university. For the data collection, stereochemistry concept inventory comprising of 20 questions was used. In the analysis of data, students’ responses in SCI were categorized. The detailed analysis of the results indicated that chemistry teacher candidates had some misconceptions concerning stereochemistry parallel to the literature. Based on these observations, some suggestions were presented for improving students’ foundational understanding about stereochemistry.

AbstractOrganic light-emitting diode (OLED) displays are now poised to be the dominant mobile display technology and are at the heart of the most attractive televisions and electronic tablets on the market today. But this begs the question: what is the next big opportunity that will be addressed by organic electronics? We attempt to answer this question based on the unique attributes of organic electronic devices: their efficient optical absorption and emission properties, their ability to be deposited on ultrathin foldable, moldable and bendable substrates, the diversity of function due to the limitless palette of organic materials and the low environmental impact of the materials and their means of fabrication. With these unique qualities, organic electronics presents opportunities that range from lighting to solar cells to medical sensing. In this paper, we consider the transformative changes to electronic and photonic technologies that might yet be realized using these unconventional, soft semiconductor thin films.
