This study examined the effect of integrating Statistical concepts on Third year student teachers’ academic performance on Heredity in Biology. The study adopted purposive sampling where 93 participants were randomly assigned into two groups, i.e. an Experimental class (n = 45) and a Control group (n = 48).Three research questions and two hypotheses guided the study. The study used a quasi-experimental pretest-posttest control group design. Data were collected using a 8-item structured questionnaire which was used to obtain data on students’ attitude towards heredity while an Achievement Test’ (AT), which comprised 4 questions, was used to measure the students’ performance in genetics. The two null hypotheses were tested using the Independent Sample T-test (at α = 0.05) while the third question was analysed using percentages.The findings from the study showed that students taught Heredity by integrating statistical concepts achieved higher scores and significantly better than those taught using conventional methods (df = 91; p = 0.001 < α = 0.05) . There was also no better achievement in favour of the male students compared to their female counter parts when taught by integrating the statistical concepts in the experimental group (df = 43; p = 0.871 > α = 0.05). It further established that students developed positive attitude towards Heredity after integrating statistical concepts in the teaching of Heredity in Biology. The study recommends among other things, that since integrating statistical concepts is found to be an effective strategy and enhanced achievement among Biology students, teachers and lecturers of this subject should accept it as one of the strategies they can use in teaching Heredity in Biology so as to enhance students’ academic performance.

This research is intended to observe the effect of through sociodrama technique in improving students’ interpersonal communication skill at the tenth-grade students of SMK Ar-Rahman Misriadi Langkat. In the research methodology, the writer used quasi-experimental design, focusing on non- equivalent control group design. In addition, to decide the sample of the research the writer used non-probability sampling technique in the form of purposive sampling technique. There were twenty four  male students who had been chosen as the research sample.The sample chosen was classified based on the interpersonal communication  skill in the lower rate. Moreover, the instrument used to decide the sample was the instrument of interpersonal communication skill which provided four options on a Likert scale. The technique of analysis was carried out by using descriptive statistics which provided empirical mean to know the average scores between the pre-test and the posttest in the experimental group and controlled group respectively. The result showed that the score of Asymp. Sig were 0.000 which meant that the interpersonal communication skill of the male students Sig < 0.05. It can be concluded that the high number of increasing of interpersonal communication skill was experienced by the male students  in the experimental group than in the controlled group. Therefore, the result of this research was used to improve the interpersonal communication skill of the tenth- grade male students  at SMK Ar-Rahman Misriadi Langkat.

This research is motivated by the low mastery of basic movements due to the incorrect way of doing the passing technique. How to teach volleyball games using the lecture method so as to make students less interested so that students become less active during the learning process. The purpose of this study was to determine whether there was effectiveness in the problem based learning model on the psychomotor outcomes of volleyball underpassing in class XI students of SMK Negeri 2 Semarang and discovery learning models on psychomotor outcomes of volleyball underpassing in class XI students of SMK Negeri 2 Semarang. The research method used in this research is Quasi Experimental Design (quasi-experimental) with the design used in this study is the Noneequivalent Control Group Design. Data collection techniques using tests. The population in this study were students of class XI SMK N 2 Semarang, with samples of class XI BDP 1 and XI UPW 1 students. The results showed that the hypothesis test was obtained t count (22.669 < 29.556) which means that the problem based learning and discovery learning models are effective in psychomotor results of passing under volleyball in class XI students of SMK N 2 Semarang. The results of the effectiveness of passing down volleyball with a problem based learning model of 83.06. While the results of the effectiveness of passing down volleyball with the discovery learning model of 89.00. Based on the results above, it can be concluded that the discovery learning learning model is more effective than problem based learning exercises for the effectiveness of passing down volleyball in class XI students of SMK N 2 Semarang, because from the data the value of the discovery learning model is greater than problem based learning.
