This study aimed at finding out the level of effectiveness of the implementation of the teaching at the  Department of  Mechanical Engineering Politeknik Negeri Bali (PNB) viewed from  the interrelatedness of the components of context, input, process, and product, This study used the evaluative study model of CIPP (Context, Input, Process, Product) and was done in two stages. The data were collected using a questionnaire, interview guide, and related documents that have proved to be highly valid and reliable. The data were analyzed descriptive-qualitatively and descriptive-quantitatively. The result showed that the implementation of the teaching program at the Department of Mechanical Engineering PNB viewed from the interrelatedness of the components of CIPP falls into the fairly effective category. On the other hand, the constraints encountered in the teaching program implementation were faced in the components of context and product. The greatest constraints were found in the variables of process and product related to the evaluation of nonacademic learning achievement.

The COVID-19 pandemic has indeed forced people to do more activities from home, including the learning process. The learning from home policy is not accompanied by rules and regulations such as what this learning process should be carried out. As a result, various learning processes emerged, from what they are to complex things. This study aims to find innovations and learning solutions during a pandemic, to support learning from home. Online learning is the only option. It's just that, based on the problems and constraints revealed, this online learning must be packaged like traditional face-to-face learning. The choice then turned to blended learning, with various adjustments. Face-to-face learning is carried out via video conference if needed only. The shortcomings are then overcome by compiling learning materials in the form of problem-based, text-based, video, or multimedia practical guides. The learning process is complemented by the opening of active interactive communication channels. Learning evaluation is carried out not only on results but also considering the process and self-evaluation. All of this learning process should be as optimal as possible using a mobile device or smartphone.

Applied Mathematics is a basic skill that determines the success of students in pursuing their education in the Department of Mechanical Engineering. Besides having to understand concepts and be able to solve cases according to the topics taught, students are also required to be able to solve mathematical engineering problems in the application of mechanical engineering. This makes it a difficult subject for the majority of students. This difficulty is overcome by applying blended learning. This is done by integrating curriculum design with strategy and use of learning technology so that innovation and teaching excellence are formed to support the learning process of students. Learning strategies that can be applied include explanations of concepts, problem-based learning, problem-solving and case discussions. This learning strategy is supported by multimedia technology and internet-based, namely video tutorials, discussion of material and examples of online-based cases and online discussion forums. The process of face-to-face learning in class is still being carried out. The key to the success of this learning lies in the ability to create interactions between students and fellow students, with teachers, with the community, with the material with the use of existing technology.

Qualified elementary teachers are teachers who have competencies that meet the demands of the 21st century and the industry revolution 4.0. The 21st century competencies are ICT competency, cultural competency, the competency to implement culture-based learning, and personal competence in the form of self-efficacy. One way for developing such competencies in the digital age is by developing a learning resource which integrates Balinese culture with technology. This learning resource helps the elementary teachers to produce a new teaching style in the classroom that can boost their competencies, thereby quality learning that meet the demands of the 21st century can be realized.

This study was aimed at finding out: 1) the difference in concept understanding and ability to solve mathematical problems between the students who were facilitated with problem-based learning model and those facilitated with conventional learning model; 2) the difference in concept understanding and ability to solve mathematical problems between the students who were facilitated with authentic assessment and those who were facilitated with conventional assessment; and 3) the effect of interaction between learning model and assessment model on concept understanding and ability to solve mathematical problems. This study was conducted at Politeknik Negeri Bali by using the 2x2 factorial experimental design. The sample consisted of 110 students. The data was collected using a test which has been validated, proved to have a reliability coefficient of 0.83 for concept comprehension test, and 0.88 for the problem-solving test. Furthermore, the data were analyzed with two-way Manova. The result of analysis showed significantly that: (1) there was a difference in concept understanding on mathematical problem-solving ability between the students facilitated with problem-based learning model and those facilitated with conventional model; (2) there was a difference in concept understanding and problem-solving ability between the students who were facilitated with authentic assessment, and those facilitated with conventional assessment; and (3) there was an effect of interaction between learning model and assessment on conceptual understanding and ability to solve mathematical problems.
