Abstract
The following research aims to describe implementation of NHT type cooperative learning models, students activities, and students communication skills with the matery of electrolyte and non-electrolyte solution at SMAN 1 Sidoarjo. The design used in this research is one shoot case study design. Obtained results in the form of (1) The implementation of the syntax of the NHT type cooperative model gets the average consecutive percentage scores at meetings 1, 2, and 3 of 3.60; 3.81; and 3,875 with the criteria is very good in everymeetings of the maximum value is 4.00. (2) Students on relevant activities which means students practice communication skills with activities according to the NHT syntax have a score of the percentage of time in a row of activities in meetings 1, 2 and 3 of 95.93%, 98.15%, and 99.34% of the total amount of learning time. (3) Students' communication skills include quality and quantity. The percentage of quantity  scores asked students to obtain sufficient criteria in succession at meetings 1, 2, and 3 of 8.33%, 19.44%, and 41.67% of the quantity of opinion obtained sufficient criteria for three meetings of 36.11%, 41.67% and 58.33%. The percentage of the quality of asking students who obtained the criteria once in a row at meetings 1, 2, and 3 was 8.33%, 11.11%, and 19.44%, the percentage of the quality of opinion of students who obtained the criteria very well for three meetings of 22.22%, 27.78% and 30.56%.
