Body expression and dance are activities that contribute to the integral well-being of people. In an educational context, the process of evaluating our students implies variations in their moods. This study tackles the states of mind that students perceive before and after the evaluation of a practice in the subject of Body expression and dance, developed through choreographies, that were, previously rehearsed, and later presented to the rest of the class in a specific session. Our main interest was the obtention of information on the states of mind of the students prior to the evaluation of their choreographies (cooperative task), and again once they had been performed. The study design consisted of two phases: two different choreographies separated by an interval of 2 months. The students were asked about their moods before and after performing their choreographies, which were evaluated. The participants, 167 in total, 35 women (20.5%) and 132 men (79.5%), aged 18 to 22 years old, filled out a POMS (Profile of Mood States) questionnaire, before and after the evaluation of each occasion. Differences were found in the stress-anxiety, vigor-activity, fatigue-immobility scales and the total mood score (PGMS). In all of them, except for the fatigue-immobility scale, we found a decrease in scores after the performance, compared to scores before. For the Stress-Anxiety factor, lower values were observed in the post-tests in comparison to the pre-tests, and also lower values in the pre- and post-test scores regarding the second choreography. We conclude that the practical evaluation of the subject through choreography modifies the mood states of the students, favoring their well-being after its execution, which is why evaluation through practice is considered a positive element in the educational process.

Logic Gate is one of the materials in the subject of Computer Systems at the level of SMK in class X. However, until now the learning media only uses textbooks, power point slides and manual simulations using blackboards. While the material about logic gates is very difficult if it is not directly simulated because it is directly related to the interaction of inputs and outputs at each logic gate. During the use of textbooks and manual simulation media students find it difficult to understand the material about this logic gate. The advantage of learning that utilizes augmented reality is an attractive display and displays 3D logic gate objects and input buttons that can be used to interact directly and the output is also in the form of 3D lamp objects, with this augmented reality technology will be very helpful and useful for simulating the gate logic is directly and easily understood by students. 3D logic gate animations are created using the 3D Blender application and the Augmented Reality process is created using the Unity and Vuforia SDK Library. This logic gate learning application has been applied to two classes, namely the control class and the experimental class. From the results of the Pre Test and Post Test that have been done, the control class has a 22.0% increase in percentage, while the experimental class has a 33.4% increase in percentage. Thus the learning application that utilizes Augmented Reality technology can be applied as a medium for learning logic gates at the vocational level of class X
