Abstract: The interest of this research is learner’s competency in using and regulating of electrical motor based on teaching models and instructional materials used. Data are obtained through quasi-experimental study with a number of 60 learners as a sample, which it was taken randomly. A sheet test and an observation sheet are used as the research instrument, which was developed and tested in advance. Data are analyzed by ANOVA, and concluded that there is a difference of the effect of learning models and forms of teaching materials used towards the learners’ competency in using and regulating of an electric motor.
Keywords: Instructional Models, Learning Materials, Competency
A person in charge of a work must be competent in that field in order to guarantee the quality of his work. Competencies represent an approach that is popular in practice [1,2]. The competence of someone is the ability to channel and apply knowledge and skills to face the new situation. This is a picture of a qualitative nature of the person's behavior when doing the job .
Competence looks of skill, power, authority, and the finesse of someone on rational action based on the expected conditions (Makmun & Abin Syamsuddin, 1996). Someone is important to have the competence to be able to contribute to something of high value at the level of individual and social life, and that makes competence as an instrument to deal with the demands and challenges of a complex .
A competency can be awakened through a variety of learning activities with opportunities for learners to conduct investigations and experiments . A considerations used in assessing learning outcomes is the success of the students to realize a theory, and analogies and represents the variables contained in the theory [6,7]. In accredit work-based learning student in connection with the development of competencies is conducted through a learning model in the form of practicum, ie meaningful as objects or concepts used in presenting something .
A model of learning is becoming a learning process that is intended to allow the learners to understand the material, namely through a systematic procedure of organizational learning experience. And this is a conceptual framework for achieving learning objectives, and serves as a guideline for the designers of learning and teachers in planning learning activities [9,10,11]. Selection of the learning model is determined by several factors, including the circumstances of a learner and the learning environment. The decision can be taken by considering a model that will be selected .
Dick and Carey model is selected in this study because of its development stages suitable as a basis to draft consisting of 10 steps with a clear relationship, uninterrupted relationship between the stage of each other. Based on the form of the strategy has been envisaged to be played when the learning process. Learning strategy here is a fusion of a sequence of events, ways of organizing the subject matter and students, equipment and materials, as well as the time spent in the learning process . Besides teacher qualifications and school facilities, another important determinant of quality of education is the teaching and learning materials. It is essential for quality materials to be made available to the teachers and students in adequate quantities to support the teaching and learning processes. Different people learn in different ways is a fact of the classroom and something that teachers often try to overcome (Online).
In practice, the learning materials are often used in the module form, but it seems not to provide maximum results. Learning materials need to be developed with opportunities for learners to build it-self. Learners as knowledge constructors share some fundamental features from, whether working individually or in groups, on traditional screen-based structures or within more of webpage hypertext architecture. They develop diverse skills in data/ media selection, generation, organization, orchestration and re-structuring. The opportunity to share the results of construction labor with others permits these active learners to gain feedback as to whether their level of understanding is sufficient to facilitate meaningful communication of ideas to others .
The packaging of teaching materials can be in variety form, namely printed materials and ingredients are not printed. In this study, the printed instructional materials used is module, and unprinted teaching materials are packaged in compact disk. The using of learning materials packed in CD can increase student motivation and student learning outcomes. Learning materials can be packaged such that fun learners, and can relieve the boredom of students when learning [15,16]. It became the basis of this study that the teaching materials are built in the form of animation that is packaged in a Compact Disk (CD), namely the use and regulation of the electric motor in the form of animation. The teaching materials are included in the experiment of learning model i.e. Dick & Carey model of learning and conventional learning models.
A Quasi-experimental design was used with 2x2 factorial design. The effects of learning models and teaching materials were analyzed in teaching the learning materials in the CD animation form and modules. The learning models used in this study are Dick & Carey model and conventional learning model. The influence of the learning model and instructional materials used were viewed in the competence of the learner in using and regulating the electric motor.
This study involved 60 students as a samples, which took randomly, and are grouped into two experimental groups. Each group consisted of 30 students. Data on students’ competency in using and regulating electric motors, is obtained through a test sheet related to the students’ knowledge and observation sheet used to see the attitude and skills of students. All the instruments used in this study was developed by the researchers and tested first to see the level of reliability and validity of the instrument. Students’ competence is determined by the composition of the assessment of knowledge, attitudes and skills in using and regulating of electricmotors. Data was analyzed by two ways ANOVA. The advanced test was done to see the best group among of the existing groups.
Data was analyzed to obtain the necessary information relating to the Mean value, Standard deviation. Summary of the results of calculations of data from each treatment group are presented in Table 1.

|Interaction of A and B||1848.1503||1||1848.1503||90.5534||2.772||Significant|
In the Table 2 appears the calculation analysis of variance between columns (learning model), obtained F = 27.3476 and pFtable= 2,772 for the significance level α = 0:05 with degrees of freedom df (1: 56). It shows the average results of the use and regulation of competence electric motor that students learned with Dick & Carey learning model (= 82.30) is higher than the average competence of the use and regulation of electric motors students who learned with conventional learning model (= 76.23).
Likewise, the results of the analysis of variance of the effect of teaching materials, obtained Fh of 31.0517 and price Ftable = 2,772 for the significance level α = 0.05 with degrees of freedom df (1: 56). It shows the average results of the use and regulation of competence electric motors students with learning materials animation higher CD (= 81.50) than the average competence of the use and regulation of electric motors students with learning materials module (= 76.10).
The results of testing the interaction between learning model with the teaching materials used, ieFh = 90.5534 and Ftable= 2,772 for the significance level α = 0:05 with dk = (1:56). On this basis it appears that the competence of the use and regulation of electric motorsor the students with learning materials animation CD packed, which learned with Dick & Carey model of learning, is higher (= 90.80) than the competence use and regulation of electric motors of students with module learning materials (= 73.70). And the competence in using and regulating of an electric motor of students with learning materials animation CD, learned with conventional learning model is lower (= 73.97) than the competence in using and regulating of the electric motor of student which learn with module learning materials (= 78.23). It shows that there is an interaction between learning models and learning materials to affect the competency of using and regulating electric motor of students. Based on further testing is done to see which of the best combination of the combination of existing treatment.
Tuckey test conducted showed Q = 12.5680 higher than Qtable = 3.03 at significance level α = 0.05. It gives the sense that the competence of the use and regulation of electric motors students with learning materials animated CD packed of the lessons learned with Dick & Carey model, is higher (= 90.80) than in the use of learning modules (= 73.70). Further calculations Q = 3.1310 smaller than Qtable = 3.03 at significance level α = 0.05 is meant that the average competence of the using and regulating of an electric motor of students with learning materials animation CD, which learned with conventional learning models, lower (= 73.97) than the competence which learn with the module learning material (= 78.23). Likewise Q = 12.3695 is higher than Qtable = 3.03 confidence level α = 0.05. It shows the average of the competence of the using and regulating electric motors of student, with learning materials animation CD packed, learned with Dick & Carey model of learning is higher (= 90.80) than the competence of students with learning materials animation CD packed, which learned with conventional learning model (= 73.97). The next test results showed Q = 3.3294 is higher than Qtable = 3.03 at significance level α = 0:05. It shows the average of the competence of the using and regulating of electric motor, which learned with learning model Dick & Carey is lower (= 73.70) than the competence of students with learning materials module, which learned with conventional learning model (= 78.23). Summary of test results from the combination treatment group are presented in Table 3 below.

 look at the instructional design as a system and consider learning is a systematically process. This systematic way of working always refer to the general stages of learning development system (Instructional Systems Development/ISD), namely stages of analysis, design, development, implementation, and evaluation. All components interact in the learning process to achieve its intended purpose. This is the determinant in this study that the competence of the students in the use and regulation of the electric motor, which is taught using learning model Dick & Carey, better than the competence of students who are taught by conventional models. All elements of the learning model role for the implementation of learning in order to obtain better results than the conventional learning model. This is in line with the statement of  that the use of Dick & Carey model of learning in the learning provides the better outcome due to the sequential stages of proper instructional designing and presentation-provided in the Dick and Carey offered models have a better understanding of the difficult, concepts by the learners.
Likewise, teaching materials are included in the study, it turns teaching materials are packaged in the form of a compact disk (in the form of animation), learning outcomes (competencies) are better, compared with the use of teaching materials in the form of modules. This is in line with the statement of the experts that, to create meaningful learning experience allowing applicable moments of student learning, instructional Several strategies are suggested: matching instructional level to students' competency levels, use of identical elements between learning and application settings , and variation in the modality of instructional delivery to promote near and far transfer of learning 
Based on the findings of this study that Dick & Carey learning model that includes instructional materials are packaged in the form of animation is much more successful than the other combinations. This implies that to get maximum learning outcomes when applying Dick & Carey model, which included teaching materials need to be made in bentu animation. The advantage of using teaching materials are packaged in the form of animation, make the learners can directly replicate all the steps shown in the animation .
