The researchers asked to what extent do middle school ELL texts depict frequency and variation of language-teaching models in illustrations and written texts. Using content analysis, they measured the range of depiction of the 4 language-teaching models and concluded that 4 of the 33 textbooks had considerable to extensive frequency and variation of L2 teaching model

The Development of Historical Instruction/Teaching Material in Senior High Schools Based on Local History with SOI Approach

ABSTRACT Purpose: The purpose of this research is to develop more comprehensive model of historical instructional materials that is a model of local history-based teaching materials and oriented to local historical events. The method used in the development of historical instructional materials is Research and Development (R & D) approach. This research is to formulate a development model of teaching materials on Indonesian history with local history. So the appropriate method in this research is the R & D method/approach.The development of historical materials based on local history will give students an understanding of the historical values that occur in their environment so that the understanding level of historical values will more achieve the target in the historical learning objectives. Method: The method used in the development of historical instructional materials is Research and Development (R & D) approach. This research is to formulate a development model of teaching materials on Indonesian history with local history. So the appropriate method in this research is the R & D method/approach. Findings: The developed product is teaching materials about Indonesian history arranged on the concept of SOI (Selecting, Organizing, and Integrating.). The development of historical teaching materials with SOI begins with the gathering of local historical sources which are relevant to the national curriculum on the history subjects. The selection result based on the observations of historical objects and oral sources is combined with existing knowledge of history and sorted which is included in national curriculum. After the materials are selected/sorted then the next stage is to organize them which are suitable with material orders (basic competence) on nasional curriculum. The last stage before organizing the teaching materials is to combine the local history with national curriculum of history subjects into the historical teaching materials. The product of teaching materials is able to accommodate the materials of local history relating to the basic competence in the national curriculum

Multimedia technologies and online task-based foreign language teaching-learning

Teaching and learning a foreign language at a distance implies many challenges, namely regarding oral skills. At Universidade Aberta (the Portuguese Open University), and taking into account its virtual pedagogical model (Pereira, 2007) and the Common European Framework of Reference for Languages (Alves, 2001), we suggest curricular paths which include online communicative practices, both oral and written, within the present pedagogical offer, following a student- centred, task-oriented approach. Thus, in this text, we share some examples of training activities in German, French and English, focusing on oral practice, and based on digital resources. These digital resources comprise multimedia materials, either produced by the teachers or the students, as well as other materials available on the web 2.0. Our teaching and research practice within the field of foreign languages and in e-learning, in particular, leads us to conclude that the multimedia resources used are suitable for the online teaching and learning of foreign languages (see third question of questionnaire), especially for professionally engaged adults, as is the case with Universidade Aberta’s students, providing them with real-life situations that foster the teaching-learning of languages in the virtual environment. We include responses to a questionnaire survey filled out by a group of students.info:eu-repo/semantics/publishedVersio
