Laboratory practices are a characteristic of undergraduate and master's programs in the science and technology field. In recent years, innovative teaching/learning approaches have been introduced in their implementation and assessment [1-2]. One proposed objective is to develop laboratory practices as a learning experience and a strategy allowing to find and build knowledge in critical and sensible scientific thinking. Thus, the laboratory activity is not considered just another activity performed by the student. This paper analyzes experiences conducted in recent years with first-year Physics laboratory practices in engineering degrees at the University of Girona. Supplementary material has been generated to the typical written script, specifically explanatory videos and minimum assessment criteria associated with the practice. Students are more receptive to videos presented by expert students than to videos presented by professors. Assessment rubrics have also been generated. One is general regarding attitudinal aspects (punctuality, attitude in the laboratory, degree of autonomy, care of experimental materials, etc.). Another is specific to the assessment of student reports. Student feedback has been collected. It was found that most students prefer video-based teaching materials to written materials and value the clear assessment of the practical exercises. Previous years' experience required students to complete a questionnaire about the practical exercises upon entering the laboratory, but most had not prepared for the practical exercises in advance, and the students' perception was negative because other subjects in the degree program did not require this prior preparation. Students' assessment of the practical exercises is now more positive, and the grades they receive are, on average, similar to those obtained before the introduction of innovative teaching methods.

The practical exercises grade for the course is complemented by a written exam.
