The sample group consisted of Pathomsuksa 6/3 students at Tatsaban ๑ Watthepmongkol​ School​ in the second semester of 2019, number 25, which were acquired by cluster random sampling. The research instrument was 1) a instructional model based on constructivist theory to enhance knowledge ability in career courses using electronic books 2) electronic books. 3) fourteen lesson plans, 4) forty items of an achievement test 30 items, 4 choices of answers, which have difficulty (P) from 0.32 to 0.75 and the power of discrimination (B) from 0.32 to 0.71 and the confidence value of 0.88 and 5) the attitude scale With electronic books Is a 5-level estimation scale. 6) the teachers’ questionnaire. The statistics used were the percentage, mean, and standard deviation. Results of the research were as follows: (1) The results of the teachers have opinions about current conditions and requirements for Career teaching activities The overall picture is at the highest level (= 4.70), students have needs in organizing activities. The overall teaching and learning was at a high level (= 4.68), (2)The instructional model based on constructivist theory to enhance knowledge ability in career courses using electronic books consisting of 6 elements as follows : element 1) principles of form element 2) objectives element 3) teaching (Syntax) there are 4 steps as follows: step 1 Motivation, step 2 Action, step 3 Creation,  steps 4 Evaluation of Knowledge 4) social system, element 5) response principle element 6) support system. (3) The results of the use of the instructional model based on constructivist theory to enhance knowledge  ability in career courses using electronic books : 3.1) The effectiveness of the instructional model based on constructivist theory to enhance knowledge ability in career courses using electronic books the standardized criteria ware 84.03/80.93 3.2) The average effectiveness of the instructional model based on constructivist theory to enhance knowledge  ability in career courses using electronic books 0.6443. 3.3) The average score of the students after using the instructional model based on constructivist theory to enhance knowledge ability in career courses using electronic books was significantly higher than that of before using the model at the .01 level. 3.4) The result of the study of attitudes toward electronic books was at the highest level (= 4.68).
