Abstract:
The purpose of this research was to compare grade 10 students learning achievement inbiology and to compare scientific process skills by using the proactive learning management, and toexamine grade 10 students attitude towards learning management by using proactive learningmanagement. The sample selected by purposive random sampling consisted of 38 grade 10 studentsin Renunakhonwitthayanukul School academic year 2018. The instruments used to collect the datawere (1) the biology learning achievement test, (2) the scientific process skill test, and (3) the attitudetoward proactive learning management questionnaire. The information obtained was analyzed using
percentage, mean, median, mode, standard deviation, coefficient variance, and relative development score.
The results showed that (1) the students percentage of learning achievement after learning was found to be higher than that of the students learning achievement before learning (14.92 %), and the students development scores after learning by using the proactive learning management were found to be between high to very high levels (76.32%), and the students relative development scores
was found to increase 62.55 %; (2) the students scores from the scientific process skills based on quality criteria showed that after learning the good - level quality score increased while the fair-level quality score decreased and there was no poor-level score, and the relative development score was found to increase 54.54 percent; (3) studying the students attitude toward the proactive learning management after learning resulted in that the students could create knowledge on their own, choose to study according to their interests, and express their opinions freely, causing students to have a high attitude score average.
