This research used to action research that result from the implementation of a
training course to promote the lesson study process for lecturers at the higher
education in the Lao PDR. This study aimed to evaluate cognitive effectiveness,

development at Souphanouvong University, Lao PDR. This paper focuses on the
relevancy assessment, implementation, and evaluation of the lesson study skills

encompassing planning, four days of training, implementing teaching and
observation in the classroom, and finally evaluating its effectiveness as a
reflection of lesson study skills, which was a portion of lecturers' professional
development. 56 lecturers from six faculties were used as a sample for training,
and 10 lecturers who voluntarily participated were used in the application.
Testing, an assessment form for the ability to design lesson plans, a lesson study
skills assessment form, and the teaching record book were research tools. The
mean, standard deviation, and t-test were applied to statistical analysis. The
findings were: 1) the cognitive effectiveness of the lesson study process was
significantly improved over criteria on a double percentage at a level of .05; 2)
the design ability of the lesson plan was at a high level; and 3) the lesson study
skills for the lecturers’ professional development results were at good levels.
This is the first application of the lesson study process in the context of higher
education in Laos. Lesson study was an approach that assisted lecturers to
increase professional competency to be true "teacher professionals" in the
future.
